Long-term Stroke and Mortality Risk in Nonagenarians Following Transcatheter Aortic Valve Insertion. Ann Thorac Surg 2024:S0003-4975(24)00372-2. [PMID: 38763221 DOI: 10.1016/j.athoracsur.2024.04.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 03/05/2024] [Accepted: 04/22/2024] [Indexed: 05/21/2024]
Abstract
BACKGROUND Limited data exist on the long-term outcomes of transcatheter aortic valve insertion (TAVI) in nonagenarian patients. The purpose of this study is to investigate the relationship between patient baseline comorbidity and frailty on the long-term outcome of the nonagenarian population. METHODS Retrospective analysis of 187 consecutive nonagenarian patients who underwent TAVI from 2009 to 2020. Multivariable models were utilized to analyze the association between basleline patient and frailty variables and mortality, stroke, and repeat hospitalization. Long-term survival was compared to an age- and sex-matched US population. RESULTS The median STS-predicted risk of mortality (STS-PROM) was 10% (IQR, 7-17%). Frailty was met in 72% of patients based on the five-meter walk test, 13% based on KCCQ-12 score, 12% based on KATZ activities of daily living, and 8% based on serum albumin levels. Procedure-related mortality occured in 3 (2%) patients and stroke in 8 (4%). The median duration of follow-up was 3.4 years. Outcomes included death in 150 (80%) patients, stroke in 15, and repeat hospitalization in 114. Multivariable analysis identified no association between any of the baseline patient variables with mortality, stroke, repeat hospitalization, or the combined outcomes (all P>0.05). One- and five-year survival rates in TAVI-treated nonagenarians were similar to age- and sex-matched controls (P=0.27). CONCLUSIONS Long-term death or stroke is independent of STS-PROM and frailty risk variables in this nonagenarian patient population who received TAVI. Furthermore, survival is similar to age- and sex-matched controls.

Single-Center Prospective Study of Cross-Clamp vs Balloon Occlusion in Robotic Mitral Surgery. Ann Thorac Surg 2024:S0003-4975(24)00291-1. [PMID: 38657703 DOI: 10.1016/j.athoracsur.2024.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 03/08/2024] [Accepted: 04/02/2024] [Indexed: 04/26/2024]
Abstract
BACKGROUND Transthoracic aortic cross-clamp and endoaortic balloon occlusion have both been shown to have comparable safety profiles for aortic occlusion. Because most surgeons use only one technique, we sought to compare the outcomes when a homogeneous group of surgeons changed their occlusion technique from aortic cross-clamp to balloon occlusion. METHODS We changed our technique from aortic cross-clamp to balloon occlusion in November 2022. This allowed us to conduct a prospective treatment comparison study in the same group of surgeons. Propensity score matching was used to match cases (balloon occlusion) 1:3 to controls (aortic cross-clamp) based on age, sex, body mass index, concomitant maze procedure, and tricuspid valve repair. RESULTS Total of 411 patients underwent robotic mitral surgery from 2020 through 2023. Propensity score matching was used to match 56 balloon occlusion patients to 168 aortic cross-clamp patients. The 224 patients were a median age of 65 years (interquartile range, 55.6-70.0 years), and 119 (53%) were men. All valves were successfully repaired. Balloon occlusion had a shorter median cardiopulmonary bypass (CPB) time compared with aortic cross-clamp (84.0 vs 94.5 minutes, P = .006). Median cross-clamp time (64.0 vs 64.0 minutes, P = .483) and total surgery time (5.9 vs 6.1 hours, P = .495) did not differ between groups. There were no in-hospital deaths. There were 5 surgeons who performed various combinations of console and bedside roles. CPB, cross-clamp, and surgery durations were not significantly affected by the different surgeon combinations. CONCLUSIONS Compared with aortic cross-clamp, balloon occlusion has similar perioperative and early postoperative outcomes. Additionally, it likely introduces a 10-minute reduction in total CPB time.

Abstract
Papillary fibroelastomas (PFEs) are small, slowly growing benign cardiac tumors with clinically significant risk of embolization. Surgical excision is the definitive treatment of symptomatic PFE and is conventionally performed through a median sternotomy. In this study, we report a series of 12 patients, who underwent robotic-assisted PFE removal at the Mayo Clinic. PFE involved the mitral valve, left atrium, and tricuspid valve. No major complications occurred after the procedure, and most patients were discharged 4 days after the surgery. On follow-up, 1 patient demonstrated pericarditis.

Abstract
OBJECTIVE Papillary fibroelastomas are associated with an increased risk of embolic strokes. Excision of papillary fibroelastomas may be the primary indication for surgery (primary) or performed during other cardiac operations (secondary). The present study summarizes our experience with primary and secondary fibroelastoma surgery. METHODS We analyzed the medical records of patients who underwent surgical excision of papillary fibroelastoma between January 1998 and February 2020. Patient characteristics, indications for operation, tumor size and location, and operative and long-term outcomes were evaluated. RESULTS Among the 294 patients (median age: 66 years, 62% female), papillary fibroelastoma was the primary indication for surgery in 136 patients (46%), and 51% of patients had a history of stroke or transient ischemic attack. When papillary fibroelastoma was a secondary indication for surgery (158 patients, 54%), the lesion was identified preoperatively in 39%. Papillary fibroelastomas were located most commonly on the aortic valve and least commonly in the right side of the heart. For valvular papillary fibroelastoma resected from a normal valve, valve shave was sufficient in 96% (196/205). Operative mortality was low in both groups (primary, 0% vs secondary, 2.5%, P = .13), and early neurologic events occurred in 1.3%. Recurrence rate was 15.8% at 10 years. The estimated survival for patients with primary papillary fibroelastoma at 10 years was 78.4%, whereas for secondary papillary fibroelastoma removal it was 53.6% (log rank, P = .003). CONCLUSIONS Resection of papillary fibroelastomas can be performed safely, with preservation of the native valve, and with low rates of neurologic events. Operative and long-term outcomes after fibroelastoma resection are excellent.

Navigating missing link: innovative cannulation for robotic mitral valve repair in the absence of inferior vena cava. J Surg Case Rep 2024; 2024:rjae172. [PMID: 38524676 PMCID: PMC10960939 DOI: 10.1093/jscr/rjae172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 02/20/2024] [Indexed: 03/26/2024] Open
Abstract
Cardiac surgeries often require the use of cardiopulmonary bypass to allow visualization and manipulation of tissues. Vascular anomalies may impose challenges with access configuration. A patient was evaluated for robot-assisted mitral valve repair and found to have an atretic inferior vena cava secondary due to chronic occlusion. The patient was cannulated arterially through the left common femoral artery, and two cannulation sites were applied for venous drainage: the right intrajugular vein and a second percutaneous access site directly into the right atrium through the chest wall. The procedure was completed without immediate complications, and the patient's perioperative course was unremarkable.

Predicting postoperative systolic dysfunction in mitral regurgitation: CT vs. echocardiography. Front Cardiovasc Med 2024; 11:1297304. [PMID: 38464845 PMCID: PMC10920321 DOI: 10.3389/fcvm.2024.1297304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 02/07/2024] [Indexed: 03/12/2024] Open
Abstract
Introduction Volume overload from mitral regurgitation can result in left ventricular systolic dysfunction. To prevent this, it is essential to operate before irreversible dysfunction occurs, but the optimal timing of intervention remains unclear. Current echocardiographic guidelines are based on 2D linear measurement thresholds only. We compared volumetric CT-based and 2D echocardiographic indices of LV size and function as predictors of post-operative systolic dysfunction following mitral repair. Methods We retrospectively identified patients with primary mitral valve regurgitation who underwent repair between 2005 and 2021. Several indices of LV size and function measured on preoperative cardiac CT were compared with 2D echocardiography in predicting post-operative LV systolic dysfunction (LVEFecho <50%). Area under the curve (AUC) was the primary metric of predictive performance. Results A total of 243 patients were included (mean age 57 ± 12 years; 65 females). The most effective CT-based predictors of post-operative LV systolic dysfunction were ejection fraction [LVEFCT; AUC 0.84 (95% CI: 0.77-0.92)] and LV end systolic volume indexed to body surface area [LVESViCT; AUC 0.88 (0.82-0.95)]. The best echocardiographic predictors were LVEFecho [AUC 0.70 (0.58-0.82)] and LVESDecho [AUC 0.79 (0.70-0.89)]. LVEFCT was a significantly better predictor of post-operative LV systolic dysfunction than LVEFecho (p = 0.02) and LVESViCT was a significantly better predictor than LVESDecho (p = 0.03). Ejection fraction measured by CT demonstrated significantly greater reproducibility than echocardiography. Discussion CT-based volumetric measurements may be superior to established 2D echocardiographic parameters for predicting LV systolic dysfunction following mitral valve repair. Validation with prospective study is warranted.

Effects of RBT-1 on preconditioning response biomarkers in patients undergoing coronary artery bypass graft or heart valve surgery: a multicentre, double-blind, randomised, placebo-controlled phase 2 trial. EClinicalMedicine 2024; 68:102364. [PMID: 38586479 PMCID: PMC10994969 DOI: 10.1016/j.eclinm.2023.102364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/20/2023] [Accepted: 11/22/2023] [Indexed: 04/09/2024] Open
Abstract
Background RBT-1 is a combination drug of stannic protoporfin (SnPP) and iron sucrose (FeS) that elicits a preconditioning response through activation of antioxidant, anti-inflammatory, and iron-scavenging pathways, as measured by heme oxygenase-1 (HO-1), interleukin-10 (IL-10), and ferritin, respectively. Our primary aim was to determine whether RBT-1 administered before surgery would safely and effectively elicit a preconditioning response in patients undergoing cardiac surgery. Methods This phase 2, double-blind, randomised, placebo-controlled, parallel-group, adaptive trial, conducted in 19 centres across the USA, Canada, and Australia, enrolled patients scheduled to undergo non-emergent coronary artery bypass graft (CABG) and/or heart valve surgery with cardiopulmonary bypass. Patients were randomised (1:1:1) to receive either a single intravenous infusion of high-dose RBT-1 (90 mg SnPP/240 mg FeS), low-dose RBT-1 (45 mg SnPP/240 mg FeS), or placebo within 24-48 h before surgery. The primary outcome was a preoperative preconditioning response, measured by a composite of plasma HO-1, IL-10, and ferritin. Safety was assessed by adverse events and laboratory parameters. Prespecified adaptive criteria permitted early stopping and enrichment. This trial is registered with ClinicalTrials.gov, NCT04564833. Findings Between Aug 4, 2021, and Nov 9, 2022, of 135 patients who were enrolled and randomly allocated to a study group (46 high-dose, 45 low-dose, 44 placebo), 132 (98%) were included in the primary analysis (46 high-dose, 42 low-dose, 44 placebo). At interim, the trial proceeded to full enrollment without enrichment. RBT-1 led to a greater preconditioning response than did placebo at high-dose (geometric least squares mean [GLSM] ratio, 3.58; 95% CI, 2.91-4.41; p < 0.0001) and low-dose (GLSM ratio, 2.62; 95% CI, 2.11-3.24; p < 0.0001). RBT-1 was generally well tolerated by patients. The primary drug-related adverse event was dose-dependent photosensitivity, observed in 12 (26%) of 46 patients treated with high-dose RBT-1 and in six (13%) of 45 patients treated with low-dose RBT-1 (safety population). Interpretation RBT-1 demonstrated a statistically significant cytoprotective preconditioning response and a manageable safety profile. Further research is needed. A phase 3 trial is planned.

Abstract
A 73-year-old woman presented to the emergency department with a syncopal episode and a history of dizzy spells. A transthoracic echocardiogram demonstrated a large left atrial mass extending into the right upper pulmonary veins. Subsequently, cardiac magnetic resonance imaging and coronary computed tomography angiography with three-dimensional reconstruction and printing of the heart and mass were performed, which demonstrated a high index of suspicion for an atypical left atrial myxoma. The mass was excised robotically, and the pathology report confirmed a diagnosis of myxoma.

Abstract
OBJECTIVE To examine the analgesic efficacy of postoperative deep parasternal intercostal plane (DPIP) blocks for patients having cardiac surgery via median sternotomy. DESIGN This single-center retrospective study compared patients receiving bilateral DPIP blocks with a matched cohort of patients not receiving DPIP blocks. SETTING Large quaternary referral center. PARTICIPANTS Adult patients admitted to the authors' institution from January 1, 2016, to August 14, 2020, for elective cardiac surgery via median sternotomy. INTERVENTIONS Patients received ultrasound-guided bilateral DPIP blocks. MEASUREMENTS AND MAIN RESULTS A total of 113 patients received a DPIP block; 3,461 patients did not. The estimated multiplicative change in cumulative opioid consumption through 24 hours was 0.42 (95% CI 0.32-0.56; p < 0.001), indicating that patients receiving DPIP blocks required 60% fewer opioids than patients who did not. Proportional odds ratios for the average pain score on postoperative day (POD) 0 was 0.46 (95% CI 0.32-0.65; p < 0.001), and POD 1 was 0.67 (95% CI 0.47-0.94; p = 0.021), indicating lower pain scores for patients receiving blocks. The exploratory analysis identified an inverse correlation between DPIP blocks and atrial fibrillation incidence (2% v 15%; inverse probability of treatment weighting odds ratio 0.088, 95% CI 0.02-0.41; p = 0.002). CONCLUSIONS The use of DPIP blocks in patients undergoing cardiac surgery via median sternotomy was associated with less opioid use and improved pain scores in the early postoperative period compared with patients not receiving blocks. Prospective randomized controlled studies should further elucidate the efficacy and risks of DPIP blocks in cardiac surgery.

Abstract
Hepatocellular carcinoma (HCC), constituting the predominant manifestation of liver cancer, stands as a formidable medical challenge. The prognosis subsequent to surgical intervention, particularly for individuals presenting with a solitary tumor, relies heavily on the degree of invasiveness. The decision-making process surrounding therapeutic modalities in such cases assumes paramount importance. This case report illuminates a rather unusual clinical scenario. Here, we encounter a patient who, following a disease-free interval, manifested an atypical presentation of HCC, specifically, a solitary cardiac metastasis. The temporal interval of remission adds an additional layer of complexity to the case. Through a multidisciplinary planning process, the decision was made for surgical removal of the metastatic tumor.

Abstract
OBJECTIVE There is controversy on how to address mild aortic root dilation during concomitant aortic valve replacement: composite aortic valve conduit replacement or separate ascending aorta and aortic valve replacement. We reviewed our experience to address the issue. METHODS We retrospectively reviewed 778 adult nonsyndromic patients with aortic root diameter 55 mm or less who received replacement of the ascending aorta and aortic valve from January 1994 to June 2017. Patients were divided into 2 groups based on the type of aortic root intervention: composite aortic valve conduit replacement in 406 patients (52%) and separate ascending aorta and aortic valve replacement in 372 patients (48%). Propensity matching was used to mitigate differences in baseline patient characteristics and produced 188 matched pairs. RESULTS Sinus of Valsalva diameter was 43 mm (39-47). Operative mortality occurred in 3 patients (2%) in the composite aortic valve conduit replacement group and in 5 patients (3%) in the separate ascending aorta and aortic valve replacement group (P = .470). Median follow-up was 9.6 years (8.4-10.1). Long-term mortality was similar in the 2 groups (P = .083). Repeat operation was performed in 13 patients (7%) in the composite aortic valve conduit replacement group and in 19 patients (10%) in the separate ascending aorta and aortic valve replacement group (P = .365). Sinus of Valsalva diameter decreased 2 mm (-4-0; median follow-up 41 months) in the propensity-matched separate ascending aorta and aortic valve replacement group. CONCLUSIONS In patients with mild aortic root dilation, separate ascending aorta and aortic valve replacement results in a similar risk of repeat operation and mortality in comparison with composite aortic valve replacement. Separate ascending aorta and aortic valve replacement is not associated with subsequent aortic root dilation on medium-term echocardiography follow-up.

Abstract
OBJECTIVE Owing to a lack of supportive data, tricuspid regurgitation (TR) is usually not addressed in patients undergoing coronary artery bypass grafting (CABG). Here we evaluated changes in TR degrees over time and its impact on survival in patients undergoing CABG. METHODS We reviewed the data of 9726 patients who underwent isolated CABG between January 2000 and January 2021. According to preoperative TR severity, patients were stratified into nonsignificant (none to trivial, mild) and significant (moderate to severe) TR groups. We excluded patients who had undergone previous tricuspid valve surgery, pacemaker placement, and concomitant valve or ablative surgery. Propensity score matching and Cox proportional hazards models were used to identify associations between TR grade and the primary outcome of all-cause mortality. The secondary outcome was change in TR severity on the last echocardiogram. RESULTS After propensity score matching, 380 patients in each group were identified. At baseline, 359 patients had moderate TR (94.5%) and 21 (5.5%) had severe TR. On the last follow-up echocardiogram, TR had improved in 40.5% of the patients in the significant TR group. Kaplan-Meier survival curves showed significantly lower survival in patients with significant preoperative TR compared to those with nonsignificant TR (P < .001). After adjusting for other confounders, survival was no worse in the patients with significant TR group (hazard ratio, 1.05; 95% confidence interval, 0.80-1.38; P = .70). CONCLUSIONS Significant preoperative TR improved in 40.5% of patients after isolated CABG. After adjusting for other factors, significant TR did not affect long-term survival.

Abstract
BACKGROUND In this study, we aimed to evaluate the educational value and students' satisfaction with the hand-made low-cost cricothyrotomy simulation model. MATERIALS AND METHODS A low-cost and hand-made model and a high-fidelity model were used to assess the students. The students' knowledge and satisfaction were evaluated using a 10-item checklist and a satisfaction questionnaire, respectively. Medical interns in the present study participated in a two-hour briefing and debriefing session held in the Clinical Skills Training Center by an emergency attending doctor. RESULTS Based on the results of data analysis, no significant differences were found between the two groups in terms of gender, age, the month of internship, and last semester's grade (P = .628, .356, .847, and .421, respectively). We also found no significant differences between our groups in terms of the median score of each item in the assessment checklist (P = .838, .736, .805, .172, .439, .823, .243, .950, .812, and .756, respectively). The study groups had no significant difference in the median total scores of the checklist as well (P = .504). Regarding the students' satisfaction, our results showed that interns evaluated their experience of the model as positive (median scores of 4 and 5 out of 5). They also gave the hand-made model a median score of 7 in comparison with the high-fidelity model and 8 out of 10 for its usability. CONCLUSION The study results showed that a low-cost model could be as effective as an expensive high-fidelity model for teaching the necessary knowledge of cricothyrotomy techniques to medical trainees.

[PMID: 37036273 DOI: 10.1002/ccd.30658] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 02/01/2023] [Accepted: 03/19/2023] [Indexed: 04/11/2023]
Abstract
BACKGROUND Obesity has been associated with an increased risk of vascular complication during percutaneous coronary intervention, but there are no data on the risk of vascular complication during percutaneous transfemoral transcatheter aortic valve insertion (TAVI). OBJECTIVES We hypothesized there would be a similar increased risk associated with TAVI. METHODS We reviewed the records of 1176 patients who received percutaneous transfemoral transcatheter aortic valve insertion from September 2015 to September 2020. All patients received 1) preoperative computed tomoraphy angiography assessment of the abdomen and pelvis to delineate iliofemoral artery anatomy, 2) ultrasound-guided percutaneous femoral arterial access, and 3) pre-closure of the delivery sheath femoral access site. Vascular complication was recorded based on definitions set forth by Valve Academic Research Consortium 3. RESULTS The median age of patients was 81 years, and 60% were men. The median body mass index (BMI) was 29 kg/m2 (range, 11-67), and 91 (8%) patients had a value ≥40 kg/m2 (i.e., morbid obesity). Delivery sheath size was 14-French in 859 (73%) patients, 16-French in 311 (26%), and 18-French in 6 (1%). Vascular complication occurred in 53 (5%) patients, including 39 (7%) among the first half of procedures and 14 (2%) among the second half (p < 0.001). When stratified by obesity status (BMI < or ≥30 kg/m2 , p < 0.001), the complication rate was 4% in nonobese patients and 5% in obese patients. Multivariable analysis showed no overall association between risk of vascular complication and BMI categories (p = 0.583)BMI continuous values (p = 0.529), or sheath size (p = 0.217). CONCLUSIONS Obesity is not associated with a vascular complication during percutaneous transfemoral transcatheter aortic valve insertion. The operation should not be denied in obese patients.

Apixaban for Anticoagulation After Robotic Mitral Valve Repair. Ann Thorac Surg 2023; 115:966-973. [PMID: 35973484 DOI: 10.1016/j.athoracsur.2022.07.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 06/04/2022] [Accepted: 07/25/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND There is no consensus regarding postoperative anticoagulation after mitral valve repair (MVRep). We compared the outcomes of post-MVRep anticoagulation with apixaban compared to warfarin. METHODS We reviewed data of 666 patients who underwent isolated robotic MVRep between January 2008 and October 2019. We excluded patients who had conversion to sternotomy and those discharged without anticoagulation or on clopidogrel (n = 40). Baseline and intraoperative characteristics and antiplatelet/anticoagulation records were collected. In-hospital and post-discharge complications and overall survival were compared. RESULTS Among the 626 studied patients the median age was 58 years (interquartile range, 51-66), 71% were male, and 1% (n = 9) had atrial fibrillation. Eighty percent (n = 499) were discharged on warfarin and 20% on apixaban (n = 127). Almost all patients (126 of 127, 99%) in the apixaban group were also on aspirin at discharge, whereas in the warfarin group only 79% (n = 395) were also on aspirin at discharge. Baseline characteristics were similar, except that the apixaban group had more female patients (46 of 127, 36% vs 136 of 499, 27%, P = .047). There were no differences in in-hospital complications, including stroke. Readmission rate was higher in the apixaban group (15 of 127, 12% vs 30 of 499, 6%, P = .02), driven mostly by postoperative atrial fibrillation (6 of 127 [5%] vs 5 of 499 [1%], respectively; P = .01). There was no difference in other complications (including bleeding and thromboembolic events), or overall mortality within 3 years. Exclusion of patients who did not receive aspirin at discharge did not affect the results. CONCLUSIONS Anticoagulation with apixaban after minimally invasive robotic MVRep is safe and has similar rates of bleeding and thromboembolism compared to patients treated with warfarin.

Abstract
BACKGROUND Left (LAAA) and right atrial appendage aneurysms (RAAA) are rare entities, and their natural history, management, and long-term outcomes are not well studied. METHODS This retrospective review includes all patients from 2000 to 2021 with atrial appendage aneurysms at our institution identified using an electronic search tool. LAAA and RAAA were confirmed using multimodality imaging and intraoperative findings. RESULTS We identified 13 (87%) patients with LAAA and 2 (13%) with RAAA. At diagnosis, 11 (73%) were female, mean age was 51.4 ± 18.8 years, and ejection fraction 56.5 ± 13.1%. Three (20%) patients had congenital heart disease including 2 (13%) with atrioventricular septal defects and 1 (7%) with congenitally corrected transposition. LAAA/RAAA was diagnosed due to new-onset atrial fibrillation (AF) in 6 (40%) patients and embolic stroke in 2 (13%). Ten patients had preexisting AF diagnosed 2.9 ± 1.4 years earlier at a mean age of 50.2 ± 15.5 years. Thrombus within the aneurysm was identified in 2 (15%) LAAA patients. All patients were on anticoagulation and follow-up of the cohort from diagnosis was 7.1 ± 6.2 years. Eleven (73%) patients were surgically managed with 7 (64%) lesions excised, 1 (9%) stapled, and 3 (27%) ligated. Postoperative complications occurred in 2 (18%) patients with 1 (7%) developing tricuspid regurgitation and another with pericardial effusion and tamponade. CONCLUSIONS Atrial appendage aneurysm is a rare disease and nearly half of patients present with AF. Surgical treatment with concomitant AF ablation is a reasonable and safe management option.

Pectoral Fascial Plane Versus Paravertebral Blocks for Minimally Invasive Mitral Valve Surgery Analgesia. J Cardiothorac Vasc Anesth 2023:S1053-0770(23)00099-X. [PMID: 36948910 DOI: 10.1053/j.jvca.2023.02.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 01/24/2023] [Accepted: 02/06/2023] [Indexed: 02/13/2023]
Abstract
OBJECTIVES This study examined the postoperative analgesic efficacy of single-injection pectoral fascial plane (PECS) II blocks compared to paravertebral blocks for elective robotic mitral valve surgery. DESIGN A single-center retrospective study that reported patient and procedural characteristics, postoperative pain scores, and postoperative opioid use for patients undergoing robotic mitral valve surgery. SETTING This investigation was performed at a large quaternary referral center. PARTICIPANTS Adult patients (age ≥18) admitted to the authors' hospital from January 1, 2016, to August 14, 2020, for elective robotic mitral valve repair who received either a paravertebral or PECS II block for postoperative analgesia. INTERVENTIONS Patients received an ultrasound-guided, unilateral paravertebral or PECS II nerve block. MEASUREMENTS AND MAIN RESULTS One hundred twenty-three patients received a PECS II block, and 190 patients received a paravertebral block during the study period. The primary outcome measures were average postoperative pain scores and cumulative opioid use. Secondary outcomes included hospital and intensive care unit lengths of stay, need for reoperation, need for antiemetics, surgical wound infection, and atrial fibrillation incidence. Patients receiving the PECS II block required significantly fewer opioids in the immediate postoperative period than the paravertebral block group, and had comparable postoperative pain scores. No increase in adverse outcomes was noted for either group. CONCLUSIONS The PECS II block is a safe and highly effective option for regional analgesia for robotic mitral valve surgery, with demonstrated efficacy comparable to the paravertebral block.

Abstract
With broadening applications of transcatheter aortic valve replacement (TAVR) and increasing use in intermediate- and low-risk patients, the incidence of surgical re-interventions after TAVR is growing. Transcatheter heart valves suffer from similar long-term complications as surgical heart valve prostheses that require surgical re-intervention, including endocarditis and structural valve deterioration. Catastrophic periprocedural complications - such as annular or aortic rupture requiring urgent surgical intervention - may also occur during TAVR procedures. This review summarizes the current knowledge on indications, methods, and outcomes of cardiac operations after TAVR, with a focus on how to improve results in a rapidly growing patient population.

Does Minimally Invasive Mitral Valve Repair Mean Less Postoperative Pain? Ann Thorac Surg 2022; 115:1172-1178. [PMID: 36395877 DOI: 10.1016/j.athoracsur.2022.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 10/21/2022] [Accepted: 11/09/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Rapid recovery after minimally invasive mitral valve (MV) repair has been demonstrated in many studies, but the issue of postoperative pain has not been fully elucidated. We evaluated pain scores and medication use in patients undergoing MV repair by minimally invasive surgery (MIS) and open sternotomy (OS). METHODS Between 2008 and 2019, 1332 patients underwent isolated MV repair by OS, and 913 underwent minimally invasive MV repair. After 1:1 propensity score matching, the study included 709 patients in each group. Opioid use was quantified as oral morphine equivalents in milligrams for each hospital day. The highest pain scores were collected from a visual analogue scale at 6-hour intervals. Predictive modeling was employed to compare pain medications and pain scores between the groups. RESULTS The postoperative median length of stay was 3 (3-4) and 5 (4-5) days for the MIS and OS groups, respectively (P < .001). The predicted geometric mean oral morphine equivalents demonstrated lower opioid use for the MIS group compared with the OS group for the first 4 days. However, the predicted mean pain score was higher in the first 24 hours for the MIS group compared with the OS group (4.7 [4.5-4.8] vs 4.4 [4.3-4.5], respectively, on a visual analogue scale of 0 to 10). CONCLUSIONS MV repair by MIS methods was associated with decreased opioid use but not with decreased postoperative pain scores. Possible explanations include the difference in incision site pain and subjective differences in postoperative pain expectations.

Abstract
Background The management of severe mitral regurgitation (MR) after transcatheter edge‐to‐edge repair (TEER) remains a clinical conundrum. Considering the growing volume of TEER, more outcomes data for mitral surgery in this cohort are needed. Methods and Results Symptomatic patients with persistent or recurrent severe MR after TEER evaluated between May 2014 and June 2021 were included. The primary outcome was all‐cause mortality in patients who were treated with surgery versus medical therapy. The Kaplan–Meier and Cox regression methods were used to report risk‐adjusted survival analyses. Among the 142 included patients, 44 (31.0%) underwent mitral surgery. Patients who underwent surgery were younger than those treated medically (74.1±8.9 versus 78.6±10.5 years, P=0.01). Major comorbidities were similar except obesity, sleep apnea, left ventricular dimensions, and ejection fraction. Society of Thoracic Surgeons Predicted Risk of Operative Mortality was 9.0±4.7 versus 7.9±4.9 in the surgical versus medical therapy groups, respectively, P=0.22. Time from TEER to detection of severe MR was similar in both groups (median [interquartile range] 97.5 [39.5–384] versus 93.5 [40–389] days in the surgical versus medical groups, respectively [P>0.05]). In the surgical group, valve replacement was performed in all patients. Operative mortality was 4.5% (observed/expected ratio 0.55), and major complications were uncommon. After risk‐adjustment, surgery was associated with significantly lower all‐cause mortality (adjusted hazard ratio, 0.33 [95% CI, 0.12–0.92], P=0.001) compared with medial therapy. Conclusions Compared with medical therapy, mitral surgery in patients with severe persistent or recurrent MR after TEER is associated with lower mortality despite the high‐risk profile of these patients. Patients with severe MR after TEER should be considered for surgery at a referral mitral surgical center.

Abstract
BACKGROUND Minimally invasive mitral valve repair (MVr) is commonly performed. Data on the outcomes of robotic MVr versus nonrobotic minimally invasive MVr are lacking. We sought to compare the short-term and mid-term outcomes of robotic and nonrobotic MVr. METHODS We reviewed all patients who underwent robotic MVr (n = 424) or nonrobotic MVr via right mini-thoracotomy (n = 86) at Mayo Clinic, Rochester, MN, from January 2015 to February 2020. Data on baseline and operative characteristics, operative and long-term outcomes were analyzed. Patients were matched 1:1 using propensity scores. RESULTS Sixty-nine matched pairs were included in the study. The median age was 59 years (interquartile range [IQR]: 54-69) and 75% (n = 103) were male. Baseline characteristics were similar after matching. Robotic and nonrobotic MVr had similar operative characteristics, except that robotic had longer cross-clamp times (57 [48-67] vs. 47 [37-58] min, p < .001) and more P2 resections (83% vs. 68%, p = .05) compared to nonrobotic MVr. There was no difference in operative outcomes between groups. Hospital stay was shorter after robotic MVr (4 [3-4] vs. 4 [4-6] days, p = .003). After a median follow-up of 3.3 years (IQR, 2.1-4.5), there was no mortality in either group, and there was no difference in freedom from mitral valve reoperations between robotic and nonrobotic MVr (5 years: 97.1% vs. 95.7%, p = .63). Follow-up echocardiogram analysis predicted excellent freedom from recurrent moderate-or-severe mitral regurgitation at 3 years after robotic and nonrobotic MVr (90% vs. 92%, p = .18, respectively). CONCLUSIONS Both short-term and mid-term outcomes of robotic and nonrobotic minimally invasive mitral repair surgery are comparable.

Abstract
OBJECTIVES Our objective is to assess whether the presence of myocardial viability is a predictor of mortality among patients undergoing coronary artery bypasss grafting (CABG) through a systematic review meta-analysis. METHODS Comprehensive review of EMBASE and PubMed in accordance with PRISMA guidelines, including studies of patients undergoing CABG with assessment of myocardial viability and recorded long-term mortality, age and sex. Studies were restricted to the last decade, and data were stratified by imaging modality (magnetic resonance imaging [MRI] or nuclear medicine). Random-effects model for assessing pooled effect, heterogeneity assessment using Chi-square and I2 statistics, publication bias assessed by funnel plots and Egger's test. RESULTS Meta-analysis of contemporary data (January 2010 to October 2020) yielded 3,621 manuscripts of which 92 were relevant, and 6 appropriate for inclusion with 993 patients. Pooled analysis showed that patients with non-viable myocardium undergoing CABG are at 1.34 times the risk of mortality compared to those with viable myocardium (95% CI 1.01-1.79, p=0.05). Subgroup analysis of the MRI or nuclear medicine modalities was not statistically significant and there was no confounding by age or sex in meta-regression. There was significant heterogeneity in imaging modality and diagnostic criteria, but heterogeneity between study findings was low with an I2 statistic of 29%. The risk of publication bias was moderate on the Newcastle-Ottawa Scale), but not statistically significant (Egger's Test coefficient=1.3, 95%CI -0.35-2.61, p=0.10). CONCLUSIONS There is a multitude of methods for assessing cardiac viability for coronary revascularisation surgery, making meta-analyses fraught with limitations. Our meta-analysis demonstrates that the finding of non-viable myocardium can not be used draw conclusions for risk assessment in coronary surgery.

Abstract
OBJECTIVES This study analyzes the safety and outcomes of mitral valve repair for degenerative mitral valve regurgitation in patients 75 years of age or older. METHODS We retrospectively reviewed the clinical results of 343 patients aged ≥75 years who underwent mitral valve repair for degenerative mitral valve regurgitation as a primary indication between January 1998 and June 2017. RESULTS The median (IQR) age of the patients was 79.4 (76.9, 82.9) years, and 132 (38.5%) patients were women. Concomitant procedures were performed in 123 patients: tricuspid surgery in 68 (19.8%) and a maze procedure or pulmonary vein isolation in 55 (16.0%). Operative mortality was 1.2%. Operative complications included atrial fibrillation in 37.9%, prolonged ventilation in 7.0%, pacemaker implantation in 3.8, renal failure requiring dialysis in 1.5, and troke in 3 (0.9%). Median follow-up was 7.4 years (IQR, 3.5-14.1 years). The cumulative incidence rates of mitral valve reoperation were 2.2%, 3.2%, and 3.2% at 1, 5, and 10 years, respectively. Overall survival at 1, 5, and 10 years were 95%, 83%, and 51%, respectively. Older age, smoking, and over and under weight were associated with increased risk of mortality, while higher left ventricular ejection fraction and hypertension were associated with reduced risk. CONCLUSIONS Mitral valve repair in elderly patients can be accomplished with low operative mortality and complications. Mitral valve repair in the elderly remains the preferred treatment for degenerative mitral regurgitation.

Abstract
Background The aim of this study was to determine the incidence, epidemiology, and
associated risk factors of bloodstream infection (BSI) in patients who had
previously undergone cardiac valve repair. Methods A population-based study that included 7 counties in southeastern Minnesota
using the expanded Rochester Epidemiology Project (e-REP) for adults
(≥18 years) who underwent valve repair between 1 January 2010 and 31
December 2018 was conducted. Electronic health records were screened for
development of BSI and infective endocarditis (IE) from the date of valve
repair through 30 July 2020. A 1:4 nested case-control analysis was
performed to determine an association, if any, of male sex, Charlson
comorbidity index (CCI), and county of residence with BSI. Results A total of 335 patients underwent valve repair, of whom 28 (8.3%) developed
an index case of BSI, with 14 episodes occurring within 1 year of surgery.
The median age of patients with BSI was 70 years, and 79% were male. The
crude incidence of BSI was 1671 cases per 100000 person-years and
Escherichia coli was the most common pathogen.
Case-control analysis demonstrated a significant correlation between CCI and
incidence of BSI (P < .001). Only 4 (14.3%)
patients developed IE concurrent with the onset of BSI, and no patients
developed IE subsequent to BSI. Conclusions The crude incidence of BSI following valve repair was higher in our e-REP
cohort than previous population-based studies, and half of the BSI cases
occurred within 1 year of surgery. Patients with a higher CCI at baseline
were at increased risk of subsequent BSI.

Abstract
Introduction: Benign cardiac tumors and tumor like conditions are a heterogeneous collection of mass lesions that vary widely in their characteristics, such as presentation, size, and location. In some instances, these tumors are found incidentally, and therefore a broad differential diagnosis should be considered. Case: An elderly male with significant unintentional weight loss and a high risk for cancer presented with an incidental valvular cardiac mass. The mass was thought to be a non-bacterial thromboendocarditis on initial clinical evaluation. After multiple imaging modalities, the mass was suspected to be a papillary fibroelastoma (PFE), which was resected due to high stroke risk and multiple previous chronic infarcts on brain MRI. Conclusion: This case highlights the need for a comprehensive cardiac evaluation of a valvular tumor to discern the etiology and rule out other underlying pathophysiological processes that may require alternative interventions to cardiac surgery.

Robotic Mitral Valve Repair: A Decade of Experience with Echocardiographic Follow-up. Ann Thorac Surg 2021; 114:1587-1595. [PMID: 34800487 DOI: 10.1016/j.athoracsur.2021.08.083] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 07/31/2021] [Accepted: 08/03/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Surgical approaches for mitral valve (MV) disease have evolved with the aim of developing minimally invasive techniques. While the safety of robotic procedures has been documented, there are limited data on long-term echocardiographic follow-up. This review demonstrates outcomes of 11 years of robotic MV repair at a single, tertiary institution. METHODS From 2008 to 2019, 843 patients underwent robotic MV repair at our institution. Repeated measures generalized least squares (GLS) modelling was used to assess the echocardiographic changes over time. RESULTS The median age was 58 years (IQR 50.8, 65.5) (591 males, 70.1%). Mechanism of MR was posterior leaflet prolapse in 479 (56.8%), bileaflet prolapse in 325 (38.6%), and anterior leaflet prolapse in 36 (4.3%). There were 3 early deaths (0.4%) and 24 early reoperations (2.8%). Echocardiographic follow up demonstrated left ventricular end systolic and diastolic dimensions, left atrial volume index and pulmonary pressure all continuously improvement up to 2 years postoperatively. Ejection fraction immediately declined postoperatively but then gradually improved to near normal over 2 years. Survival and freedom from reoperation at 10 years were 93% and 92.6%, respectively. When surveyed after dismissal, 93.4% reported their activity level at or above their peers and 93.3% reported no activity limitation from cardiac symptoms. CONCLUSIONS Robotic MV repair is safe and effective with excellent long-term results, including echocardiographic parameters that demonstrated early improvement in cardiac chamber size and maintenance of postoperative cardiac function. Exceedingly low mortality rates and freedom from reoperation are comparable to those of the standard open repair.

Effects of Altering Mitochondrial Antioxidant Capacity on Molecular and Phenotypic Drivers of Fibrocalcific Aortic Valve Stenosis. Front Cardiovasc Med 2021; 8:694881. [PMID: 34250048 PMCID: PMC8263922 DOI: 10.3389/fcvm.2021.694881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 05/17/2021] [Indexed: 11/25/2022] Open
Abstract
Background: While a small number of studies suggest that oxidative stress has an influential role in fibrocalcific aortic valve disease (FCAVD), the roles of specific antioxidant enzymes in progression of this disease remain poorly understood. Here, we focused on selectively altering mitochondrial-derived oxidative stress—which has been shown to alter progression of a myriad of age-associated diseases—on the progression of molecular and phenotypic drivers of FCAVD. Methods: We generated low-density lipoprotein receptor-deficient, Apolipoprotein B100-only mice (LA) that were either haploinsufficient for MnSOD (LA-MnSOD+/−) or genetically overexpressing MnSOD (LA-MnSODTg/0). After 6 months of Western diet feeding, mice underwent echocardiography to assess valvular and cardiac function and tissues were harvested. Quantitative-RT PCR, immunohistochemistry, and histopathology were used to measure changes in molecular pathways related to oxidative stress, calcification, and fibrosis. Results: While reductions in MnSOD increased oxidative stress, there was not an overt phenotypic effect of MnSOD deficiency on valvular and cardiac function in LA-MnSOD+/− mice. While markers of canonical bone morphogenetic protein signaling tended to increase in valve tissue from LA-MnSOD+/− (e.g., p-SMAD1/5/8 and osterix), we did not observe statistically significant increases in osteogenic signaling. We did, however, observe highly significant reductions in expression of osteopontin, which were associated with significant increases in calcium burden in LA-MnSOD+/− mice. Reciprocally, genetically increasing MnSOD did not preserve valve function in LA-MnSODTg/0, but we did observe slight reductions in p-SMAD1/5/8 levels compared to their non-transgenic littermates. Interestingly, overexpression of MnSOD dramatically increased expression of osteopontin in valve tissue from LA-MnSODTg/0 mice, but was not sufficient to attenuate calcium burden when compared to their LA-MnSOD0/0 littermates. Conclusions: Collectively, this study demonstrates that maintenance of mitochondrial antioxidant capacity is important in preventing accelerated disease progression in a mouse model of FCAVD, but that effectively altering mitochondrial antioxidant capacity as a monotherapeutic approach to slow key histopathological and molecular drivers of FCAVD remains biologically and therapeutically challenging.

MnSOD protects against vascular calcification independent of changes in vascular function in hypercholesterolemic mice. Atherosclerosis 2021; 331:31-37. [PMID: 34147244 DOI: 10.1016/j.atherosclerosis.2021.06.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 05/05/2021] [Accepted: 06/04/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND AND AIMS The overall goal of this study was to determine the effects of MnSOD-deficiency on vascular structure and function in hypercholesterolemic mice. Previous work suggested that increases in mitochondrial-derived reactive oxygen species (ROS) can exacerbate vascular dysfunction and atherosclerosis. It remains unknown, however, how MnSOD-deficiency and local compensatory mechanisms impact atherosclerotic plaque composition. METHODS AND RESULTS We used a hypercholesterolemic mouse model (ldlr-/-/ApoB100/100; LA), either wild-type for MnSOD (LA-MnSOD+/+) or MnSOD-haploinsufficient (LA-MnSOD+/-), that was fed a western diet for either 3 or 6 months. Consistent with previous reports, reductions of MnSOD did not significantly worsen hypercholesterolemia-induced endothelial dysfunction in the aorta. Critically, dramatic impairment of vascular function with Nox2 inhibition or catalase pretreatment suggested the presence of a significant NO-independent vasodilatory mechanism in LA-MnSOD+/- mice (e.g. H2O2). Despite remarkably well-preserved overall vascular relaxation, loss of mitochondrial antioxidant capacity in LA-MnSOD+/- mice significantly increased osteogenic signalling and vascular calcification compared to the LA-MnSOD+/+ littermates. CONCLUSIONS Collectively, these data are the first to suggest that loss of mitochondrial antioxidant capacity in hypercholesterolemic mice results in dramatic upregulation of NADPH oxidase-derived H2O2. While this appears to be adaptive in the context of preserving overall endothelium-dependent relaxation and vascular function, these increases in ROS appear to be remarkably maladaptive and deleterious in the context of vascular calcification.

Severe tricuspid bioprosthetic valve stenosis as an unusual cause of pulmonary embolism: a case report. EUROPEAN HEART JOURNAL-CASE REPORTS 2021; 5:ytab169. [PMID: 34124568 PMCID: PMC8189298 DOI: 10.1093/ehjcr/ytab169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 02/18/2021] [Accepted: 04/07/2021] [Indexed: 12/03/2022]
Abstract
Background Bioprosthetic tricuspid valve stenosis (TS) is an uncommon and frequently under-diagnosed condition. Although the resulting right heart failure symptoms are well-known, the associated thrombogenic potential is under-recognized. Case summary A 44-year-old woman with bioprosthetic tricuspid valve (TV) replacement in 2001 was referred for urgent consultation due to acute worsening of dyspnoea and severe swelling and pain in her left arm and neck. She was diagnosed with atrial fibrillation 6 months before the presentation and was found to have right atrial (RA) thrombus with pulmonary embolism and extensive retrograde venous extension 1 month prior. Review of studies done at her local institution revealed 10 mmHg mean gradient (MG) across the bioprosthetic TV that was only reported as mild–moderate TS. Echocardiography done at our instruction confirmed suspicion of severe TS with calcified immobile leaflets. Computed tomography showed persistent RA thrombus and therefore surgical replacement of the TV was undertaken. Subsequently, patient’s dyspnoea rapidly improved. Discussion Progressive dyspnoea and symptoms of right heart failure in a patient with a history of bioprosthetic TV replacement should be investigated for prosthetic valve dysfunction. Due to its rarity, TS diagnosis can be overlooked on routine echocardiography. In our patient, despite a measured MG of 10 mmHg, the presence of critical TS was not initially recognized. As TS is associated with increased thrombogenic potential and given the rare occurrence of in situ RA thrombosis, physicians must have a high index of suspicion for TS in the appropriate clinical context.

701. Blood Stream Infection And Risk Of Endocarditis Following Cardiac Valve Repair: A Population-Based Study. Open Forum Infect Dis 2020.

Abstract
Background Bloodstream infections (BSIs) confer an increased risk of infective endocarditis (IE) in patients with a prosthetic cardiac valve. This relationship is less well established in patients undergoing valve repair. We conducted a retrospective population-based study to determine the incidence of BSIs following valve repair and identify risk factors associated with the development of IE. Methods The Rochester Epidemiology Project (REP) data linkage system was used to identify all persons who underwent valve repair in a 7-county region in Southeastern Minnesota between January 1, 2010 and December 31, 2018. Medical records were screened for the development of a BSI from time of procedure until May 15, 2020. Patients were classified as having BSI only, BSI with IE at outset, or BSI with subsequent development of new IE. IE at outset was defined as cases where IE was diagnosed at the time of initial positive blood culture. Results A total of 387 patients underwent valve repair surgery. A total of 31 (8%) patients subsequently developed a BSI, 4% within one year of surgery. Seventeen patients underwent mitral repair with annuloplasty, 9 underwent tricuspid annuloplasty, and 5 had concurrent repairs. Median time to the development of BSI was 338 days. Of the 31 patients with BSI, 4 (13%) had BSI with IE at outset. No patients developed IE subsequent to BSI, Enterococcus spp. was responsible for 3 cases of IE, and MSSA for 1. All cases occurred within one year of surgery. Given the low incidence, statistical analysis of associated risk factors for IE was not feasible. All patients with BSI and IE at outset, however, died by the end of the study period, versus 11/27 in the BSI only group. Conclusion Incidence of BSIs was higher in patients undergoing cardiac valve repair than in the general population. The incidence of IE with a BSI was 13%, which is lower than what has been previously published. It is notable that all cases of IE occurred within one year of surgery. Recognizing that endothelialization of device surfaces occurs, it is tempting to speculate that the risk of IE may be time dependent and may decline over time. Subsequent investigation of this theory is underway. Disclosures Larry M. Baddour, MD, Boston Scientific (Consultant)

Effect of Earlier Atrioventricular Valve Intervention on Survival After the Fontan Operation. Am J Cardiol 2020; 137:103-110.

Abstract
Whereas the prevalence and impact of atrioventricular valve (AVV) regurgitation in patients with single ventricle physiology has become increasingly apparent, the optimal timing for valve intervention is unclear. To investigate this, we performed a retrospective review of all 1,167 patients from the Mayo Clinic Fontan database. Thirteen percent (153 patients) had AVV repair or replacement during their staged single ventricle palliation. We found that patients with right ventricular morphology and common AVV were at increased risk for AVV intervention. Patients who underwent AVV intervention had increased risk of death/transplant compared with those who did not (hazards ratio [HR] = 1.75, 95% CI 1.37 to 2.23, p <0.001). With respect to valve intervention timing, whereas AVV intervention before Fontan presented similar risk for death/transplant compared with no AVV intervention (HR = 0.85, 95% CI 0.32 to 2.27, p = 0.74), intervention at time of Fontan had a significantly higher risk (HR = 1.46, 95% CI 1.09 to 1.97, p = 0.01), and intervention after Fontan had a much more substantial risk (HR = 3.83, 95% CI 2.54 to 5.79, p <0.001). AVV repair failure occurred in 11% of patients. In terms of relative risk of valve repair versus replacement, in post-Fontan AVV intervention patients, AVV replacement carried a 2.9 fold risk of death/transplant compared with AVV repair. In conclusion, AVV disease remains a considerable challenge for durable Fontan physiology. This data demonstrates that earlier intervention on valve pathology improves survival with the Fontan circulation. Continued surveillance of single ventricle patients and prompt referral of those with valve pathology can improve outcomes in this challenging population.

Comparative Effectiveness of Mechanical Valves and Homografts in Complex Aortic Endocarditis. Ann Thorac Surg 2020; 111:793-799.

Abstract
BACKGROUND The ideal surgical reconstruction of the aortic root in patients with complex endocarditis is controversial. We compared the short- and long-term outcomes between mechanical valves, bioprostheses, and homografts. METHODS We identified all patients undergoing an operation for active complex aortic endocarditis at our institution between 2003 and 2017. We grouped patients according to those who received a mechanical valve, bioprosthesis, or homograft. We used multiple logistic regression and proportional hazards models. To minimize confounding by indication, we used marginal risk adjustment to simulate that every patient would undergo (contrary to fact) all 3 operations. RESULTS Of 159 patients with complex active endocarditis, 48 (30.2%) had a valve plus patch reconstruction, and 85 (53.4%) had a root replacement. Of all, 50 (31.5%) had a mechanical valve, 56 (35.2%) had a bioprosthesis, and 53 (33.3%) had a homograft. The groups were similar in age, sex, body mass index, comorbid conditions, organism, abscess location, and mitral involvement (all P > .05). However, patients receiving mechanical reconstructions were more likely to have native valve endocarditis (46% vs 37.5% vs 17%; P = .005) and less likely to undergo root replacement (32% vs 28.6% vs 100%; P < .001). Marginal risk-adjusted operative mortality was lowest for mechanical valves (4.8%) and highest for homografts (16.9%; P = .041). Long-term survival after root replacement was worse with homografts than with mechanical valve conduits (adjusted hazard ratio, 2.9; P = .045). CONCLUSIONS In patients with complex endocarditis, mechanical valves are associated with similar, if not better, short- and long-term outcomes compared with homografts, even after adjusting for important baseline characteristics and limiting the analysis to root replacements only.

Abstract
BACKGROUND Previous studies suggest that patients with prior or current hematologic malignancy are at increased risk of intraoperative and postoperative complications when undergoing cardiac surgery. The aim of this review was to compare clinical outcomes of patients with a history of hematologic malignancy to those of similar patients with no known blood dyscrasia. METHODS From January 1993 to June 2017, 37,839 patients underwent elective cardiac surgery at Mayo Clinic. We matched 612 patients (1.6%) with a history of hematologic malignancy to 612 controls, and compared operative details, early postoperative complications, and late survival. RESULTS The median age of matched patients with hematologic malignancy was 71 years (interquartile range [IQR], 62 to 77) and 71 years (IQR, 62 to 77) for patients without cancer. Patients with prior diagnosis of malignancy had lower hemoglobin levels, 12.8 (IQR, 11.5 to 13.8) vs 13.5 (IQR, 12.2 to 14.6; P < .001), but similar platelet counts, 195 (IQR, 147 to 263) vs 203 (IQR, 170 to 245; P = .533). Patients with malignancy were at greater risk of receiving postoperative blood transfusions (47.4% vs 35.6%, P < .001). However, reoperations for postoperative bleeding (4.7% vs 3.3%, P = .253) and stroke (1.3% vs 1.3%, P > .999) were similar. Thirty-day mortality was 3.3% among patients with hematologic malignancy and 1.5% among matched controls (P = .061). Overall survival among patients with cancer was reduced (P < .0001). CONCLUSIONS Although late survival is reduced in patients with hematologic malignancies, early outcomes are generally similar to those of matched controls. Therefore, surgery should not be withheld from patients with a diagnosis of hematologic malignancy who would benefit from cardiac procedures.

Abstract
BACKGROUND The effect of intraoperative fluid balance on postoperative acute kidney injury (AKI) in cardiac surgical patients is poorly defined. METHODS In this retrospective study of patients undergoing aortic valve replacement for aortic stenosis, the primary outcome of interest was postoperative AKI. Secondary outcomes were postoperative fluid balance, cardiac index, vasopressor use, hospital-free days, stroke, myocardial infarction, hospital readmission, and 30- and 90-day mortality. RESULTS A total of 2327 patients were analyzed. Positive intraoperative fluid balance was associated with lower odds of AKI; the lowest odds were in the 20- to 39-mL/kg group (odds ratio, 0.56; 95% confidence interval, 0.38-0.81; P = .002). Positive intraoperative fluid balance was associated with a lower postoperative fluid balance. Increased ultrafiltration volume was associated with increased postoperative fluid resuscitation and vasopressor use. AKI was associated with increased 30- and 90-day mortality. Increased fluid balance was associated with increased odds of myocardial infarction and 30-day mortality. Increased ultrafiltration volume was associated with increased odds of 30- and 90-day mortality. CONCLUSIONS In patients who underwent aortic valve replacement for aortic stenosis, positive intraoperative fluid balance was associated with decreased odds of AKI. Patients developing AKI had increased 30- and 90-day mortality. Although the overall incidence was low, increased intraoperative fluid balance was associated with myocardial infarction and 30-day mortality, whereas increased ultrafiltration volume was associated with 30- and 90-day morality. Prospective studies are needed to better define proper intraoperative fluid management in patients undergoing cardiac surgery.
