[PMID: 38817650 PMCID: PMC11135327 DOI: 10.4330/wjc.v16.i5.274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 02/16/2024] [Accepted: 04/16/2024] [Indexed: 05/23/2024] Open
Abstract
BACKGROUND Mitral valvuloplasty using artificial chordae tendineae represents an effective surgical approach for treating mitral regurgitation. Achieving precise measurements of artificial chordae tendineae length (CL) is an important factor in the procedure; however, no objective index currently exists to facilitate this measurement. Therefore, preoperative assessment of CL is critical for surgical planning and support. Four-dimensional x-ray micro-computed tomography (4D-CT) may be useful for accurate CL measurement considering that it allows for dynamic three-dimensional (3D) evaluation compared to that with transthoracic echocardiography, a conventional inspection method. AIM To investigate the behavior and length of mitral chordae tendineae during systole using 4D-CT. METHODS Eleven adults aged > 70 years without mitral valve disease were evaluated. A 64-slice CT scanner was used to capture 20 phases in the cardiac cycle in electrocardiographic synchronization. The length of the primary chordae tendineae was measured from early systole to early diastole using the 3D image. The primary chordae tendineae originating from the anterior papillary muscle and attached to the A1-2 region and those from the posterior papillary muscle and attached to the A2-3 region were designated as cA and cP, respectively. The behavior and maximum lengths [cA (ma), cP (max)] were compared, and the correlation with body surface area (BSA) was evaluated. RESULTS In all cases, the mitral anterior leaflet chordae tendineae could be measured. In most cases, the cA and cP chordae tendineae could be measured visually. The mean cA (max) and cP (max) were 20.2 mm ± 1.95 mm and 23.5 mm ± 4.06 mm, respectively. cP (max) was significantly longer. The correlation coefficients (r) with BSA were 0.60 and 0.78 for cA (max) and cP (max), respectively. Both cA and cP exhibited constant variation in CL during systole, with a maximum 1.16-fold increase in cA and a 1.23-fold increase in cP from early to mid-systole. For cP, CL reached a plateau at 15% and remained elongated until end-systole, whereas for cA, after peaking at 15%, CL shortened slightly and then moved toward its peak again as end-systole approached. CONCLUSION The study suggests that 4D-CT is a valuable tool for accurate measurement of both the length and behavior of chordae tendineae within the anterior leaflet of the mitral valve.

Abstract
PURPOSE To compare the outcomes of left circumflex artery (LCx) revascularization using an internal thoracic artery (ITA) or radial artery (RA) as the second arterial graft. METHODS Patients who underwent primary isolated coronary artery bypass grafting with left anterior descending artery revascularization using an ITA and LCx revascularization using another bilateral ITA (BITA group) or an RA (ITA-RA group) were included. All-cause mortality (primary endpoint), cardiac death, major adverse cardiac events, in-hospital death, and deep sternal wound infection (secondary endpoints) were evaluated. RESULTS Among 790 patients (BITA, n = 548 (69%); ITA-RA, n = 242 (31%)), no significant difference in all-cause mortality between the groups was observed (hazard ratio (HR): 0.87; 95% confidence interval (CI): 0.67-1.12; p = 0.27) during follow-up (mean, 10 years). Multivariate analysis revealed that the BITA group exhibited significantly lower rates of long-term all-cause mortality (HR: 0.63; 95% CI: 0.48-0.84; p = 0.01). In the propensity-matched cohort (n = 480, 240 pairs), significantly fewer all-cause deaths occurred in the BITA group (HR: 0.66; 95% CI 0.47-0.93; p = 0.02). There were no significant differences in secondary outcomes. CONCLUSIONS When used as second grafts for LCx revascularization, ITA grafts may surpass RA grafts in reducing all-cause mortality 10 years postoperatively.

Abstract
BACKGROUND Median sternotomy is the most performed procedure in cardiac surgery; however, sternal displacement and bleeding remains a problem. This study aimed to investigate whether sternal reconstruction using a sandwiched three-piece bioresorbable mesh plate can prevent postoperative sternal displacement and bleeding more than a bioresorbable pin. METHODS Patients (n = 218) who underwent median sternotomy were classified according to whether a sandwiched three-piece bioresorbable mesh plate and wire cerclage (group M, n = 109) or a bioresorbable pin and wire cerclage (group P, n = 109) were used during sternal reconstruction. The causes of postoperative sternal displacement and bleeding with computed tomography data were analyzed and compared between the groups. RESULTS The preoperative patient characteristics did not significantly differ between the groups. However, the evaluation of sternal and substernal hematoma on postoperative day 5 using computed tomography showed sternal displacement in 4 (4%) and 22 (20%) patients, and substernal hematoma in 17 (16%) and 41 (38%) patients in groups M and P, respectively; this difference was significant. Furthermore, the amount of bleeding at 6 h postoperatively was lower in group M than in group P (235 ± 147 vs. 284 ± 175 mL, p = 0.0275). Chest reopening, intubation time, and length of intensive care unit and hospital stays did not differ between the groups. The evaluation of substernal hematoma based on computed tomography yielded a significantly lower for group M than for group P, revealing that the mesh plate was an independent predictor of substernal hematoma prevention. CONCLUSION Sternal fixation with a three-piece bioresorbable mesh plate could prevent postoperative sternal displacement, bleeding, and substernal hematoma more than sternal fixation with a pin.

Use of Renal Near-Infrared Spectroscopy and Urinary Neutrophil Gelatinase-Associated Lipocalin Monitoring as Indicators of Acute Kidney Injury in Pediatric Cardiac Surgery. J Clin Med 2023; 12:jcm12062085. [PMID: 36983088 PMCID: PMC10056572 DOI: 10.3390/jcm12062085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 02/28/2023] [Accepted: 03/06/2023] [Indexed: 03/09/2023] Open
Abstract
Acute kidney injury (AKI) is a common complication following cardiac surgery under cardiopulmonary bypass (CPB) in children. A prospective study for examining urinary neutrophil gelatinase-associated lipocalin (NGAL) and renal near-infrared spectroscopy (NIRS) trends during AKI was conducted among pediatric patients undergoing cardiac surgery with CPB. Urinary NGAL showed a significant difference between intensive care unit admission (0 h) and 2 h post-admission (p < 0.001) and remained significant up to 4 h (p < 0.05). The renal NIRS in the AKI group showed a significant rate of decrease and lower values during the intraoperative period (p < 0.05). The cumulative median saturation of renal regional saturation of oxygen (rSO2) during CPB was 1637.5% min in the AKI group and 943.0% min in the non-AKI group. The median renal rSO2 scores at a reduction of 20% and 25% were significantly higher (p < 0.001) in the AKI group. Our results suggest that monitoring renal rSO2 scores and limiting their decline might be useful in preventing AKI. The combination of NGAL, renal rSO2, and renal rSO2 scores might be useful in the early diagnosis of AKI during pediatric cardiac surgery.

Abstract
Systemic lupus erythematosus is a chronic autoimmune disease that affects most tissues. Cardiovascular events are critical, life-threatening, long-term complications of systemic lupus erythematosus (SLE). We report our single-center experience of performing cardiovascular surgery in patients with SLE while avoiding postoperative complications. We also suggest a new approach for cardiopulmonary bypass and perioperative management. We applied the antiphospholipid antibody syndrome (APS) severity classification published by the Japan Intractable Disease Information Center to patients with SLE for perioperative management. Patients with Grade III or higher severity are treated with a slightly relaxed version of catastrophic APS therapy. This treatment modality includes glucocorticoids, anticoagulation, intravenous immunoglobulin, and plasma exchange. Between April 2010 and January 2021, 26 patients (2 males, 24 females) with SLE underwent cardiovascular surgery. The mean age was 74.2 ± 13.0 years (38-84 years). The primary outcomes were in-hospital mortality and long-term results, and the secondary outcomes were related to bleeding/embolization and coagulation function/platelet count. A subset analysis was performed to examine treatment efficacy in the APS Grade III or higher group. Of the 26 patients, 17 underwent valve surgery, 4 underwent isolated coronary artery bypass grafting, and 5 underwent thoracic aortic aneurysm surgery. There were no in-hospital deaths or associated bleeding/embolic complications. Postoperative antithrombin III decreased in patients who underwent valvular and aortic surgery, and platelet counts recovered to preoperative levels within 7 to 10 days. The 5- and 10-year survival rates were 80.5% and 53.7%, respectively. In addition, there were 10 patients with APS Grade III or higher, but there was no significant difference in the frequency of complications other than platelet recovery after treatment. The surgical outcome of open-heart surgery in patients with SLE was good. Surgical treatment of cardiovascular disease in these patients is difficult and complex. We focused on blood coagulation abnormalities and treated each patient by selecting the best individual treatment protocol according to the severity of the disease, taking into account the risk of bleeding and thrombosis. Management of blood coagulation function in these patients is essential, and careful therapeutic management should be considered during open-heart surgery.

Abstract
Sutureless offers an alternative to standard valves in surgical aortic valve replacement (SAVR). We sought to confirm the efficacy and safety of the Perceval sutureless valve in Japanese patients. Prospective observational study of 204 patients who underwent SAVR with Perceval at 19 sites in Japan between March and December 2019. The primary outcomes were 30-day mortality and postoperative complications; the secondary outcome was all-cause mortality at 1 year. Efficacy outcomes were changed in New York Heart Association (NYHA) class, pressure gradients, effective orifice area (EOA), EOA indexed to body surface area (EOAi) and severity of aortic regurgitation. Mean age was 77.7 years, 62.7% were female. Procedural success rate was 99.0%. The median cross-clamp and cardiopulmonary bypass times were 68.0 and 108 min. Perceval size S and M were implanted in 95 (46.6%) and in 76 (37.3%) of patients, respectively. The 30-day and late mortality rate were 0.5% and 4.4%, while the new permanent pacemaker implantation rate was 4.4%. Mean pressure gradient was 13.0 mmHg at discharge, reaching 11.0 mmHg at 1 year; while the mean EOA was 1.5 cm2 at discharge remaining stable up to 1 year. No moderate or severe leakages were present at discharge or at 1 year. NYHA class improved by ≥ 1 level in 55.1% of the patients at discharge and in 69.4% of the patients at 1 year. 1-year outcomes of SAVR with the Perceval sutureless valve in Japanese patients were favorable. This valve offers a promising alternative to conventional biological AVR in this Japanese population.

Abstract
OBJECTIVES The reduction of postoperative acute kidney injury in patients undergoing cardiopulmonary bypass surgery using an oxygen delivery-guided perfusion strategy (oxygen delivery strategy) for cardiopulmonary bypass management compared with a fixed flow perfusion (conventional strategy) remains controversial. The purpose of this study was to determine whether a oxygen delivery strategy would reduce the incidence of postoperative acute kidney injury in patients undergoing cardiopulmonary bypass surgery. METHODS We randomly enrolled 300 patients undergoing cardiopulmonary bypass surgery. Patients were randomly assigned to a oxygen delivery strategy (maintaining a oxygen delivery index value >300 mL/min/m2 through pump flow adjustments during cardiopulmonary bypass) or a conventional strategy (a target pump flow was determined on the basis of the body surface area). The primary end point was the development of acute kidney injury. Secondary end points were the red blood cell transfusion rate and number of red blood cell units, intubation time, postoperative length of stay in the intensive care unit and the hospital, predischarge estimated glomerular filtration rate, and hospital mortality. RESULTS Acute kidney injury occurred in 20 patients (14.6%) receiving the oxygen delivery strategy and in 42 patients (30.4%) receiving the conventional strategy (relative risk, 0.48; 95% confidence interval, 0.30-0.77; P = .002). The secondary end points were not significantly different between strategies. In a prespecified subgroup analysis of patients who had nadir hematocrit less than 23% or body surface area less than 1.40 m2, the oxygen delivery strategy seemed to be superior to the conventional strategy and the existence of quantitative interactions was suggested. CONCLUSIONS An oxygen delivery strategy for cardiopulmonary bypass management was superior to a conventional strategy with respect to preventing the development of acute kidney injury.

Abstract
Abstract
Background
Studies have demonstrated the efficacy of oxygen delivery-guided perfusion (ODGP) in preventing postoperative acute kidney injury, but the benefit of ODGP for delirium has not been confirmed. We retrospectively investigated the risk factors for postoperative delirium in patients who underwent ODGP (with oxygen delivery index [DO2i] > 300 mL/min/m2).
Methods
Consecutive patients who underwent on-pump cardiovascular surgery with ODGP from January 2018 to December 2020 were retrospectively analyzed. In addition to examining patients’ DO2i during cardiopulmonary bypass (CPB), we quantified the two primary DO2 components-hematocrit (Hct) and pump flow. Delirium was defined based on the Intensive Care Delirium Screening Checklist (ICDSC). Patients were divided into three groups: no delirium (ICDSC score = 0), subsyndromal delirium (ICDSC score = 1–3), and clinical delirium (ICDSC score ≥ 4).
Results
Multivariate analysis identified only the number of red blood cell (RBC) units transfused, intubation time, and the cumulative time below the Hct threshold of 25% as predictive factors of postoperative delirium. Although patients with higher ICDSC scores had greater hemodilution during CPB, ODGP resulted in a higher pump flow, and DO2i was maintained above 300 mL/min/m2, with no significant difference between the three groups.
Conclusions
A low Hct level during CPB with ODGP, the number of RBC units transfused, and intubation time were associated with postoperative delirium. Further investigations are needed to determine the ability of ODGP to prevent low Hct during CPB.

Abstract
Background: Frailty is an important prognostic factor in patients with cardiovascular diseases (CVD), and patients with CVD have a high rate of concurrent psycho-emotional stress, as well as depressive mood and anxiety symptoms. Despite this, few reports have examined the effects of the efficacy of Phase II cardiac rehabilitation (CR) in frail patients, including improvements in anxiety levels. Methods and Results: In all, 137 patients (mean [±SD] age 65.8±13.0 years; 71% male) who participated in Phase II CR and were assessed after CR completion were included in this study. Patients were evaluated using the Kihon Checklist (KCL) form at the beginning of CR and were divided into the 3 groups according to KCL scores: frail (n=34, 25%), pre-frail (n=40, 29%), and non-frail (n=63, 46%). Physical function and anxiety levels were compared among the 3 groups. The pre-frail and frail groups had significantly higher state anxiety and trait anxiety than the non-frail group (P<0.01). At the end of Phase II CR, all 3 groups showed significant improvements in the 6-min walking distance (P<0.05). State anxiety improved significantly in the non-frail and pre-frail groups, whereas trait anxiety only improved in the non-frail group. Conclusions: Physical function was improved in frail patients who participated in Phase II CR. However, there was no significant improvement in their level of anxiety.

Abstract
In the surgical repair of the tetralogy of Fallot with a narrow pulmonary valve annulus, the transannular patch method is used for right ventricular outflow tract repair. To prevent pulmonary regurgitation and valve calcification, we created and applied a new transannular patch method using pedicled own pericardium in a 5-month-old boy with tetralogy of Fallot. After closing the ventricular septal defect as usual with a 0.4 mm Gore-Tex sheet, we decided that the pulmonary valve could not be spared, because the pulmonary valve opening size was 6 mm. After removing the right ventricular abnormal myocardium, each edge of the pedicled own pericardium patch was sewn from 5 mm above the pulmonary valve commissures toward the basis of the pulmonary valve ring. The transannular patch was created using a Gore-Tex graft sawn to the right ventricular outflow tract. Echocardiography performed 6 months post surgery showed no pulmonary stenosis and trivial pulmonary insufficiency.

Abstract
BackgroundIn cases of systematic lupus erythematosus (SLE) that lead to surgery due to the development of heart diseases such as valvular disease, ischemic heart disease and aortic aneurysm, early detection and careful monitoring are important. An absence of background diseases or immunopathological examination of the myocardial tissue in SLE cases with cardiovascular lesions demonstrates the lack of knowledge in this area. In recent years, however, there have been reports of neutrophil extracellular traps being involved in the fulminant onset of SLE.ObjectivesThis study aimed to analyze clinically and immunohistopathologically the pathophysiology of heart diseases associated with SLE.MethodsWe performed left atrial appendage resection in 34 patients, including patients with cardiovascular lesions, who underwent heart surgery for SLE complications from 2012 to 2021. Tissue analysis was conducted in 9 cases. The left atrial appendage, in cases of non-collagen valvular disease, was used as the control. Tissue staining of cardiomyocytes was carried out by adding anti-neutrophil extracellular(NE) antibodies(Abs) to anti-human IgG antibody (Ab), anti-IgM Ab and anti-C3 Ab.ResultsOf the 34 SLE patients 14 had valvular disease, 8 had ischemic heart disease and 12 had aneurysms. Preoperative SLE activity was relatively stable with only 1 patient below the CH50 standard and 6 patients above the anti-DNA Ab standard. The Ab positivity rate for the patients in this study was higher than that of the 687 SLE patients who were previously tested in 2019. The presence of anti-CL Abs was 55.6%, which was higher than the 25.5% observed in previous SLE patients. In this study, anti-SS-A and anti-RNP Abs tended to be relatively numerous. An example of immunohistochemical staining of IgG in the left atrial appendage is presented (Figure 1a). IgG deposits were not observed on the left side of the myocardial fibers in the control group, whereas IgG deposits were observed on the right side in the SLE group. Deposits were also observed in tissues that were not located in the affected areas. The presence or absence of tissue deposition in the myocardial fibers and clinical findings in 2 cases of the control group and 9 cases of the SLE complication group are reported in Table 1. IgG deposits were found in the myocardial fibers of 6 of the 9 patients in the SLE complication group, and deposits were found in the left atrial appendage tissue regardless of the type of heart disease, suggesting a potential change in the heart tissue. In the SLE group, 5 cases were positive for antiphospholipid (APS) Abs, while 7 cases were positive for either anti-SS-A or anti-RNP Abs. Only 2 cases had elevated preoperative anti-DNA Ab and complement reduction. Of the SLE complication group, 2 of the 9 cases were negative for all Abs but IgG deposits were observed in a case. Of these 4 cases were selected and stained with anti-IgM, anti-C3 and anti-NE Abs. However IgM and C3 deposits were only observed in one patient who developed myocardial infarction at the age of 39 and was triple positive for APS, anti-SS-A and anti-RNP Abs (Figure 1b). There were also no NE deposits in any of the cases. Even if complement and anti-DNA Ab levels in the serum are normal, attention should be paid to heart disease complications during the long-term observation of SLE patients. In particular, attention should be paid to various autoantibody-positive cases such as APS, anti-SS-A Ab and anti-RNP Ab. The anti-NE Ab was not stained in this study because the tissue was different from the lesion site and because it occurred during the chronic course.ConclusionIn SLE patients who developed cardiovascular lesions and required surgery, immunological abnormalities may occur in the myocardial tissue even if serum complement and anti-DNA Ab levels are stable.References[1]Stephane Zuily et al.

Abstract
Mid-aortic syndrome (MAS) is a rare vascular disorder that causes refractory hypertension. A 76-year-old woman was hospitalized for acute heart failure (HF) with drug-resistant hypertension; other comorbidities included epigastric artery rupture, old myocardial infarction, an intraventricular thrombus, and a cerebral artery aneurysm. Angiography revealed severe narrowing of the descending aorta, which led to the diagnosis of MAS. Although intensive medical treatment improved her HF, optimal blood pressure (BP) could not be achieved. Percutaneous coronary intervention and surgical bypass for diseased aorta was then performed in two stages, resulting in the achievement of optimal BP and alleviation of HF.

Surgical treatment of acute aortic dissection in a patient with SLE and prior antiphospholipid syndrome on therapy for over 30 years: a case report. BMC Cardiovasc Disord 2022; 22:216. [PMID: 35562652 PMCID: PMC9103044 DOI: 10.1186/s12872-022-02659-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 05/02/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND In patients with systemic lupus erythematosus (SLE), lengthy treatment and long-term steroid use are the main risk factors for developing aortic aneurysms or aortic dissections. In patients with cardiac tamponade, hemodynamic collapse may lead to acute renal and hepatic failure. CASE PRESENTATION We report the successful treatment of a 55-year-old woman with SLE since the age of 21. She suddenly felt chest pain approximately 2 weeks before developing fever and vomiting and was admitted to our hospital. Initially, she had severe liver dysfunction and was admitted to the hepatology department, where treatment for fulminant hepatitis was initiated. However, computed tomography (CT) showed an acute aortic dissection (DeBakey type II) and severe bloody pericardial effusion. Therefore, we performed emergency pericardial drainage. Plasma exchange therapy was initiated as emergency aortic surgery was deemed impossible due to impaired liver function tests and coagulation. Ten days later, the patient developed peritonitis due to small bowel perforation, and laparotomy was performed for abscess drainage and perforation closure. She had received steroid pulse therapy at the age of 21. At 40 years of age, she developed deep vein thrombosis due to antiphospholipid antibodies and was prescribed prednisolone. She was ambulatory at 3 months after the onset of acute aortic dissection, and CT revealed a rapidly enlarging true aneurysm in the distal arch. We performed elective aortic surgery. Although there were no antiphospholipid antibodies, surgery could have led to a devastating antiphospholipid syndrome. Therefore, we decided to treat the patient with triple therapy. Methylprednisolone was intravenously administered intraoperatively and at 1 day postoperatively. The patient was discharged without complications after returning to her usual oral prednisolone regimen. CONCLUSIONS The patient described herein had a systemic circulatory failure due to cardiac tamponade, accompanied by liver failure. This condition is a significant cause of death in patients with aortic dissection-associated SLE and is extremely dangerous. However, multi-specialty intervention helped the patient recover, and she has been attending the outpatient clinic. Aortic surgery requiring hypothermia in SLE patients with antiphospholipid syndrome and a history of thrombocytopenia or thrombosis requires a multi-disciplinary treatment team, including cardiac surgeons and medical experts.

Abstract
Atypical Shone's complex is a rare congenital anomaly involving a left-sided obstructive lesion of two or three cardiovascular levels. A 70-year-old man with dyspnea on exertion was diagnosed with severe aortic stenosis (AS) with a bicuspid valve, complicated by severe aortic coarctation (CoA) and a double-orifice mitral valve. He underwent surgery for AS and CoA in one session. It is important to search for complicated malformations, even in cases of bicuspid aortic valve found in old age.

Pseudoaneurysm with a fistula to the right ventricle late after surgical repair of type A aortic dissection in a patient with systemic lupus erythematosus. J Cardiothorac Surg 2022; 17:83. [PMID: 35477534 PMCID: PMC9044762 DOI: 10.1186/s13019-022-01827-5] [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: 06/11/2021] [Accepted: 04/11/2022] [Indexed: 11/18/2022] Open
Abstract
Background Pseudoaneurysm with a shunt to the right ventricle after aortic repair for acute aortic dissection is an extremely rare and life-threatening condition. Surgical treatment is unavoidable, but surgery is complicated, and there are some pitfalls. This study describes the reoperation performed in a patient at a high surgical risk by clarifying the shunt site using multimodality imaging before surgery. Case presentation A 69-year-old woman with a history of systemic lupus erythematosus (SLE) and Sjogren’s syndrome presented with a pseudoaneurysm 1 year after emergency surgery for acute type A aortic dissection. Eight years after the first surgery, she experienced sudden chest pain and presented to the emergency department. Her dyspnea worsened; therefore, echocardiography and three-dimensional computed tomography (3DCT) were performed, and a pseudoaneurysm and shunt to the right ventricle were identified. The medical team attempted to close the shunt with a percutaneous catheter but was unsuccessful, and she was referred to our department for surgical treatment. The pseudoaneurysm originating from the proximal side of the aorta was large (diameter = 55 mm), and echocardiography-gated 3DCT identified the shunt from the pseudoaneurysm to the right ventricle. First, extracorporeal circulation was initiated, and resternotomy was performed. We could not insert the left ventricular venting tube from the right side because of the pseudoaneurysm size. Instead, the tube was inserted from the left atrial appendage. We found a half-circumferential disengaged anastomosis around the proximal anastomosis, which formed the large pseudoaneurysm leading to a fistula in the right ventricle. We closed the fistula and performed a Bentall operation. The patient had a good postoperative course and was discharged on postoperative day 21. She continued treatment for SLE and Sjogren’s syndrome, and her inflammatory reaction improved. Conclusions We performed a Bentall operation and fistula closure with resternotomy in a patient with type A aortic dissection with SLE and Sjogren’s syndrome. Multimodal imaging is essential in defining the pseudoaneurysm and the fistula surrounding the anatomy while ensuring their resolution and guiding the approach for operation.

Abstract
We report a case of a 79-year-old man for a mycotic aortic arch aneurysm caused by Clostridium perfringens. The patient who had been hospitalized for cholangitis two months prior revisited the hospital for fever and left precordial pain. He was suspected of an infected aortic aneurysm in the distal arch due to emphysematous changes observed. After antibiotics treatment, the emphysematous changes disappeared. However, he underwent urgent total arch replacement due to a new ulcer-like projection and enlargement of the aortic aneurysm, which were observed at that time. Clostridium-infected infectious aneurysms require not only treatment for vascular lesions but also scrutiny of complications, such as cancer.

Abstract
Background Advanced glycation end-products, indicated by skin autofluorescence (SAF) levels, could be prognostic predictors of all-cause and cardiovascular mortality in patients with diabetes mellitus (DM) and renal disease. However, the clinical usefulness of SAF levels in patients with heart failure (HF) who underwent cardiac rehabilitation (CR) remains unclear. This study aimed to investigate the associations between SAF and MACE risk in patients with HF who underwent CR. Methods This study enrolled 204 consecutive patients with HF who had undergone CR at our university hospital between November 2015 and October 2017. Clinical characteristics and anthropometric data were collected at the beginning of CR. SAF levels were noninvasively measured with an autofluorescence reader. Major adverse cardiovascular event (MACE) was a composite of all-cause mortality and unplanned hospitalization for HF. Follow-up data concerning primary endpoints were collected until November 2017. Results Patients’ mean age was 68.1 years, and 61% were male. Patients were divided into two groups according to the median SAF levels (High and Low SAF groups). Patients in the High SAF group were significantly older, had a higher prevalence of chronic kidney disease, and more frequently had history of coronary artery bypass surgery; however, there were no significant between-group differences in sex, prevalence of DM, left ventricular ejection fraction, and physical function. During a mean follow-up period of 590 days, 18 patients had all-cause mortality and 36 were hospitalized for HF. Kaplan–Meier analysis showed that patients in the high SAF group had a higher incidence of MACE (log-rank P < 0.05). After adjusting for confounding factors, Cox regression multivariate analysis revealed that SAF levels were independently associated with the incidence of MACE (odds ratio, 1.86; 95% confidence interval, 1.08–3.12; P = 0.03). Conclusion SAF levels were significantly associated with the incidence of MACE in patients with HF and may be useful for risk stratification in patients with HF who underwent CR.

Abstract
BACKGROUND Coronary artery bypass grafting is a surgical treatment for ischemic heart disease. Although development in surgical technique and improvement of perioperative management reduced the postoperative complications, some patients still delayed in progress of postoperative rehabilitation. In this study, we aimed to investigate the effect of daily intake of an herbal medicine-containing drink for rehabilitation after surgery in patients with ischemic heart disease.
AIM To investigate the effect of taking an herbal medicine-containing, commercially available drink for postoperative rehabilitation in those patients.
METHODS Patients who underwent isolated off-pump coronary artery bypass (OPCAB) surgery were divided into two groups depend on the timing of the admission to the hospital: the Yunker (YKR) group, that consumed one bottle of a caffeine-free nutritional supplement drink on a daily basis and the control group (CTL) that underwent regular rehabilitation.
RESULTS A total of 229 patients (CTL = 130, YKR = 99) were enrolled. No significant differences were observed in the baseline characteristics between the two groups. The YKR group had a significantly increased number of daily steps postoperatively (P < 0.05) and had significantly lower postoperative serum tumor necrosis factor-alpha levels (P < 0.01), while no significant differences were observed in the levels of other inflammatory or stress-related cytokines (interleukin-6, adiponectin, superoxide dismutase, and urine 8-hydroxy-2′-deoxyguanosine) between the two groups. Also, the YKR group showed a significant improvement in the Hospital Anxiety and Depression Score (P < 0.05). Moreover, there were no differences in postoperative complications and the duration of postoperative hospital stay between the two groups.
CONCLUSION Our results demonstrated that the daily intake of an herbal medicine-containing drink after OPCAB surgery may have beneficial effects on cardiac rehabilitation by reducing inflammation markers and depression.

Abstract
BACKGROUND Middle aortic syndrome is a rare disease. Several surgical treatments are available; however, the optimal treatment strategy and long-term outcomes remain unelucidated. We herein report the 5-year outcomes of six patients treated with extra-anatomical bypass surgery for middle aortic syndrome. CASE PRESENTATIONS Between 2013 and 2016, six patients underwent extra-anatomical bypass for middle aortic syndrome at our institute: three had Takayasu's arteritis, one had vessel vasculitis, and two had middle aortic hypoplastic syndrome of unknown origin. The patients included five women and one man, with a mean age of 59.7 years. Four patients had uncontrolled hypertension and were receiving antihypertensive medications. The mean ankle-brachial pressure index was .61. The three patients with Takayasu's arteritis were hospitalized for congestive heart failure. These patients underwent bypass surgery from the descending aorta to the infrarenal abdominal aorta, and one also underwent concomitant heart surgery. The patient with microscopic polyangiitis underwent Y-grafting with an aortic aneurysmectomy. Subsequently, bypass surgery was performed from the descending aorta to the graft via the diaphragm. The two patients with unknown causes underwent bypass surgery from the proximal descending aorta to the distal descending thoracic aorta. There were no early or late deaths at the 5-year follow-up. We did not observe any changes in anastomotic site stenosis or new aneurysmal changes during the follow-up period. The number of antihypertensive medications was reduced in all cases, and critical symptoms, including headache, severe abdominal pain, claudication, and heart failure, improved in all patients. The ankle-brachial pressure index increased to 1.11 and did not change for five years. Renal function remained stable, and the brain natriuretic peptide level decreased from 302.8 to 74.5 pg/mL at follow-up. CONCLUSION Extra-anatomical bypass for middle aortic syndrome is safe and effective, and can help prevent renal failure, and relieve critical ischemic symptoms.

Abstract
This review aimed to discuss the anatomical properties of the left atrial appendage (LAA), its relationship with atrial fibrillation (AF), effectiveness of LAA occlusion (LAAO), techniques, and new devices used to perform this procedure. An electronic search was performed to identify studies, in the English language, on LAA management. Searches were performed on PubMed Central, Scopus, and Medline from the dates of database inception to February 2020. For the assessed papers, data were extracted from the reviewed text, tables, and figures, by two independent authors. Anticoagulant therapy for patients with AF has proven beneficial and is highly recommended, but it is challenging for many patients to maintain optimal treatment. Surgery is the most cost-effective option; surgical methods include simple LAA resection, thoracoscopic surgery, and catheter treatment. Each procedure has its advantages and disadvantages, and many prospective studies have been conducted to evaluate various treatment methods. In managing the LAA, dissection of the LAA, such as changes in its shape and size due to remodeling during AF, changes in autonomic nerve function, and thrombosis, must be understood anatomically and physiologically. We believe that early treatment intervention for the LAA should be considered particularly in cases of recurrent AF. Conclusion: SLET under artificial pneumothorax is feasible and safe in minimally invasive McKeown esophagectomy.

Abstract
OBJECTIVE The aim of this study was to examine whether preoperative phase angle (PhA) measured by bioelectrical impedance analysis was associated with a hospital-acquired functional decline in older patients undergoing cardiovascular surgery. METHODS This was an observational study of prospectively collected data of 114 patients (>65 y of age) with cardiovascular disease who underwent elective cardiovascular surgery between September 2019 and August 2020. Patients were classified into tertiles based on PhA levels. Factors associated with the occurrence of hospital-acquired functional decline (postoperative recovery to preoperative physical function was not possible) were analyzed using univariate and multivariate analyses. RESULTS Patients in the low PhA group were significantly older than those in the middle and high PhA groups; were predominantly women; had higher New York Heart Association cardiovascular and EuroSCORE severity scores; and had significantly lower levels of body mass index, Geriatric Nutritional Risk Index, hemoglobin, and albumin. There was a significant correlation between PhA and nutrition and physical function. The incidence of hospital-acquired functional decline occurred in 26.3% of all patients, with a significantly higher incidence in patients in the low PhA group. Multivariate analysis showed that PhA was extracted as a factor for the hospital-acquired functional decline in all the models. CONCLUSIONS PhA was associated with hospital-acquired functional decline in older patients undergoing cardiovascular surgery. PhA is likely to be a comprehensive indicator of physical health that indicates nutritional status, physical function, and geriatric syndrome (frailty/sarcopenia), and is an important predictor of hospital-acquired functional decline in this group of older patients.
