Investigation of outcomes following transcatheter edge to edge repair of the mitral valve versus medical management alone in patients with cardiogenic shock and mitral regurgitation. AMERICAN HEART JOURNAL PLUS : CARDIOLOGY RESEARCH AND PRACTICE 2024; 45:100430. [PMID: 39184147 PMCID: PMC11342276 DOI: 10.1016/j.ahjo.2024.100430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 07/20/2024] [Accepted: 07/22/2024] [Indexed: 08/27/2024]
Abstract
Study objective Assessing if Transcatheter Edge to Edge Repair (TEER) with Mitraclip™ in patients with moderate to severe mitral regurgitation (MR) and cardiogenic shock (CS) improves outcomes compared to medical management alone. Design A single-center, retrospective study was performed in an urban tertiary referral center. Setting Rush University Medical Center, United States. Participants Adult patients presenting with CS and moderate to severe MR between 2012 and 2021 were included. Interventions Undergoing Mitral TEER with Mitraclip versus medical management alone. Main outcome measures Major adverse cardiovascular events (MACE) defined as cardiovascular death, heart failure admission, stroke, and myocardial infarction assessed at 30 days, 6 months, and 1 year. The secondary outcome was a change in New York Heart Association (NYHA) classification at 30 days and 6 months. Results There were 28 patients included in the medical management and 33 in the mitral valve TEER groups. There was a decreased MACE in the intervention group at 30 days (24.2 % vs. 46.4 %, p ≤0.001) and 6 months (27 % vs. 75 %, p = 0.002), though not at 1 year (29.4 % vs. 41.7 %, p = 0.42). At 30 days, more patients in the mitral valve TEER group improved to NYHA classes I/II compared to medical management alone (10 [35.7 %] vs. 16 [50 %], p = 0.043). There were no differences in NYHA classes I/II at 6 months (7 [43.7 %] vs. 13 [54.2 %], p = 0.63). Conclusion Mitral valve TEER using the Mitraclip™ system improves mid-term cardiovascular compared to medical management alone in patients with CS but does not improve mortality.

Abstract
BACKGROUND Transcatheter edge-to-edge repair (TEER) with MitraClip is a safe and effective alternative to surgical mitral valve repair/replacement in patients with high operative risk. Pleth Variability Index (PVI) is a non-invasive, dynamic index based on analysis of the respiratory variations in the plethysmographic waveform recorded transcutaneously by the pulse oximeter. OBJECTIVES The objective of the study was to evaluate if the hemodynamic effect of improved left-sided output after successful transcatheter mitral valve repair would lead to a significant change in PVI, and if it would correlate with the decrease in left atrial pressure (LAP). DESIGN Prospective, observational cohort study (ClinicalTrials.gov NCT03993938). SETTING Single academic hospital in Detroit, Michigan (USA), from October 2019 to February 2021. PARTICIPANTS The authors included adult patients with severe mitral regurgitation who underwent successful MitraClip placement. MEASUREMENTS AND MAIN RESULTS Of 30 patients, all components of the LAP (a wave, v wave, and mean) decreased significantly after successful MitraClip placement (P < .01). The median (IQR) PVI increased from 21 (11-35) to 23 (13-38) after clip placement; however, this change was not statistically significant (P = .275). No significant correlation between change in PVI and change in LAP was observed (P = .235). CONCLUSIONS In patients with severe mitral regurgitation, successful MitraClip resulted in a significant reduction in LAP without a significant change in PVI. A larger sample size may provide more insight on the utility of using PVI as an indicator of LAP change in patients with mitral regurgitation.

Abstract
AIMS Achieving optimized guideline-directed medical therapy (GDMT) is recommended prior to transcatheter mitral valve edge-to-edge repair (M-TEER) for secondary mitral regurgitation (SMR). We aimed to propose and validate an easy-to-use score for assessing the quality of GDMT in patients with heart failure with reduced ejection fraction (HFrEF) undergoing M-TEER. METHODS AND RESULTS Among the 1641 EuroSMR patients enrolled in the EuroSMR Registry who underwent M-TEER, a total of 1072 patients [median age 74, interquartile range (IQR) 67-79 years, 29% female] had complete data on GDMT and a left ventricular ejection fraction ≤ 40% and were included in the current study. We proposed a GDMT score that considers the dosage levels of three medication classes (angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists), with a maximum score of 12 points indicating optimal GDMT. The primary outcome was all-cause mortality. The median GDMT score was 4 points (IQR 3-6). All three domains of the scoring system were associated with all-cause mortality (P < 0.05 for all). The overall GDMT score was associated with all-cause mortality (hazard ratio 0.90, 95% confidence interval 0.86-0.95 for each 1-point increase in the GDMT score). This association remained significant after adjusting for renal function and co-morbidities. CONCLUSIONS This study demonstrates the utility of a simple GDMT scoring system for assessing the adequacy of GDMT in HFrEF patients with relevant SMR undergoing M-TEER. The GDMT score has potential applications in guiding the design of future clinical trials and aiding clinical decision-making processes.

Abstract
Severe acute mitral regurgitation after myocardial infarction includes partial and complete papillary muscle rupture or functional mitral regurgitation. Although its incidence is <1%, mitral regurgitation after acute myocardial infarction frequently causes hemodynamic instability, pulmonary edema, and cardiogenic shock. Medical management has the worst prognosis, and mortality has not changed in decades. Surgery represents the gold standard, but it is associated with high rates of morbidity and mortality. Recently, transcatheter interventions have opened a new door for management that may improve survival. Mechanical circulatory support restores vital organ perfusion and offers the opportunity for a steadier surgical repair. This review focuses on the diagnosis and the interventional management, both surgical and transcatheter, with a glance on future perspectives to enhance patient management and eventually decrease mortality.

Abstract
Transcatheter edge-to-edge mitral valve repair is a minimally invasive treatment option for selected patients with moderate to severe or severe mitral regurgitation. Although transcatheter edge-to-edge mitral valve repair offers a significant step forward in the management of mitral regurgitation, the rate of procedural-related complications is not trivial. High-quality periprocedural imaging is important for optimal patient selection and procedural success. In this review, we present a step-by-step approach of the recommended echocardiographic views for transcatheter edge-to-edge mitral valve repair.

Abstract
The safety and feasibility are still not well known for exercise-induced mitral regurgitation (MR). This study is aimed to assess and compare the hemodynamic and symptomatic changes in patients with significant secondary MR during exercise stress echocardiography (ESE) before and after transcatheter edge-to-edge repair (TEER). The study included a total of 15 patients with secondary MR who underwent ESE before and after TEER using the MitraClip system (Abbott, Abbott Park, IL, USA). Echocardiographic data of ESE were collected both before the procedure and during the follow-up visit at 3 months. During the one-year postoperative observation period, the rate of readmission due to heart failure was 13% (n = 2), with no recorded fatalities. Although no significant differences of ESE data were observed in exercise-induced pulmonary hypertension or cardiac output before and after the repair, the severity of MR was significantly improved after the procedure, both at rest (2 [2-3] vs. 1 [1-2], p = 0.0125) and during ESE (3 [3-3] vs. 1 [1-1], p < 0.0001). Furthermore, the New York Heart Association Functional Classification was improved (3 [3-3] vs. 1 [1-1], p < 0.0001) after treatment. For a supplemental analysis, MR during ESE was significantly improved not only in cases with atrial secondary MR but also in ventricular secondary MR. Transcatheter edge-to-edge repair for exercise-induced MR resulted in a significant improvement in postoperative MR severity and subjective symptoms. These results are novel, as they have not been extensively reported previously, particularly among Japanese patients.

Correlates and prognostic implications of LVEF reduction after transcatheter edge-to-edge repair for primary mitral regurgitation. Eur Heart J Cardiovasc Imaging 2023; 25:136-147.

Abstract
AIMS To explore the characteristics and outcomes of patients undergoing transcatheter edge-to-edge repair (TEER) for primary mitral regurgitation (MR) according to the presence of left ventricular ejection fraction (LVEF) reduction post-procedure. METHODS AND RESULTS We retrospectively analysed 317 individuals [median age 83 (interquartile range, 75-88) years, 197 (62.1%) males] treated with an isolated, first-time TEER that was concluded by a successful clip deployment. Stratified by LVEF change at 1-month compared with baseline, the cohort was evaluated for residual MR and heart failure (HF) indices up to 1-year, as well as all-cause mortality and HF hospitalizations at 2-years. Overall, 212 (66.9%) patients displayed LVEF reduction, which was mainly driven by lowered total stroke volume and diffuse hypocontractility. While post-procedural MR, transmitral mean pressure gradient, and functional status were comparable in the two study groups, patients with LVEF reduction exhibited a greater decline in filling pressures intra-procedurally; left ventricular mass index, pulmonary arterial systolic pressure, and serum natriuretic peptide level at 1-month; and walking limitation at 1-year. Also, by 2 years, they were less likely to die (13.3% vs. 5.7%, P = 0.019), be readmitted for HF (17.1% vs. 9.0%, P = 0.033), and experience either of the two (23.8% vs. 12.7%, P = 0.012). Lastly, LVEF reduction was the only 1-month echocardiographic parameter to independently confer an attenuated risk for the composite of deaths or HF hospitalizations (HR 0.28, 95% CI 0.10-0.78, P = 0.016). CONCLUSION LVEF reduction at 1-month post-TEER for primary MR is associated with better clinical outcomes, possibly reflecting a more pronounced unloading effect of the procedure.

Abstract
Background The clinical significance of mitral annular calcification (MAC) in patients undergoing mitral transcatheter edge-to-edge repair is not well understood. There is limited evidence regarding the feasibility, durability of repair, and the prognostic value of MAC in this population. We sought to examine the prognostic value of MAC, its severity, and its impact on procedural success and durability of mitral transcatheter edge-to-edge repair. Methods and Results We reviewed the records of 280 patients with moderate-severe or severe mitral regurgitation who underwent mitral transcatheter edge-to-edge repair with MitraClip from March 2014 to March 2022. The primary end point was cumulative survival at 1 year. Independent factors associated with the primary end point were identified using multivariable Cox regression. Among 280 patients included in the final analysis, 249 had none/mild MAC, and 31 had moderate/severe MAC. Median follow-up was 23.1 months (interquartile range: 11.1-40.4). Procedural success was comparable in the MAC and non-MAC groups (92.6% versus 91.4%, P=0.79) with similar rates of residual mitral regurgitation ≤2 at 1 year (86.7% versus 93.2%, P=0.55). Moderate/severe MAC was associated with less improvement in New York Heart Association III/IV at 30 days when compared with none/mild MAC (45.8% versus 14.3%, P=0.001). The moderate/severe MAC group had lower cumulative 1-year survival (56.8% versus 80.0%, hazard ratio [HR], 1.98 [95% CI, 1.27-3.10], P=0.002). Moderate/severe MAC and Society of Thoracic Surgeons predicted risk of mortality for mitral valve repair were independently associated with the primary end point (HR, 2.20 [1.10-4.41], P=0.02; and HR, 1.014 [1.006-1.078], P=0.02, respectively). Conclusions Mitral TEER is a safe and feasible intervention in selected patients with significant MAC and associated with similar mitral regurgitation reduction at 1 year compared with patients with none/mild MAC. Patients with moderate/severe MAC had a high 1-year mortality and less improvement in their symptoms after TEER.

[PMID: 36975864 PMCID: PMC10051684 DOI: 10.3390/jcdd10030100] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 02/21/2023] [Accepted: 02/24/2023] [Indexed: 03/03/2023] Open
Abstract
BACKGROUND The noninvasive assessment of myocardial work (MW) allows for the evaluation of left ventricular (LV) performance by considering the effect of LV afterload. This study aims to evaluate the acute and chronic impact of transcatheter edge-to-edge repair (TEER) on MW parameters and LV remodeling in patients with severe primary mitral regurgitation (PMR). METHODS A total of 71 patients (age: 77 ± 9 years, females: 44%) with moderate-to-severe or severe PMR (effective regurgitant orifice: 0.57 ± 0.31 cm2; regurgitant volume: 80 ± 34 mL; LV end-systolic diameter: 42 ± 12 mm) underwent TEER after a global assessment by the heart team. MW indices were evaluated before the procedure, at hospital discharge, and at 1-year follow-up. LV remodeling was described as the percentage variation in LVEDV between baseline and 1-year follow-up. RESULTS TEER caused an acute reduction in LVEF, global longitudinal strain (GLS), global MW index (GWI), work efficiency (GWE), and mechanical dispersion (MD) and a significant increase in wasted work (GWW). One year after the procedure, GLS, GWI, GWE, and MD recovered, whereas GWW remained significantly impaired. Baseline GWW (β = -0.29, p = 0.03) was an independent predictor of LV reverse remodeling at 1-year follow-up. CONCLUSIONS In patients with severe PMR undergoing TEER, the acute reduction in LV preload causes significant impairment to all the parameters of LV performance. Baseline GWW was the only independent predictor of LV reverse remodeling, suggesting that a lower myocardial energetic efficiency in the context of chronic preload increase might impact the left ventricular response to mitral regurgitation correction.

Abstract
Acute mitral valve regurgitation (MR) is an emergency condition that requires an early diagnosis of the etiology and rapid management. Surgical intervention is the first-line treatment for acute severe MR. However, many patients are denied surgical intervention due to the acute risk of surgery. Transcatheter mitral valve repair (TMVr) is a less invasive technique and becoming a potential alternative to surgery in inoperable patients but is underrepresented in the literature. This review aims to discuss the published data on the use of TMVr in unstable MR patients presenting with acute or critical cardiac conditions.

Abstract
Background Transcatheter valvular interventions affect cardiac and hemodynamic physiology by changing ventricular (un-)loading and metabolic demand as reflected by cardiac mechanoenergetics. Real-time quantifications of these changes are scarce. Pressure-volume loop (PVL) monitoring appraises both load-dependent and load-independent compounds of cardiac physiology including myocardial work, ventricular unloading, and ventricular-vascular interactions. The primary objective is to describe changes in physiology induced by transcatheter valvular interventions using periprocedural invasive biventricular PVL monitoring. The study hypothesizes transcatheter valve interventions modify cardiac mechanoenergetics that translate into improved functional status at 1-month and 1-year follow-up. Methods In this single-center prospective study, invasive PVL analysis is performed in patients undergoing transcatheter aortic valve replacement or tricuspid or mitral transcatheter edge-to-edge repair. Clinical follow-up is per standard of care at 1 and 12 months. This study aims to include 75 transcatheter aortic valve replacement patients and 41 patients in both transcatheter edge-to-edge repair cohorts. Results The primary outcome is the periprocedural change in stroke work, potential energy, and pressure-volume area (mmHg mL-1). The secondary outcomes comprise changes in a myriad of parameters obtained by PVL measurements, including ventricular volumes and pressures and the end-systolic elastance-effective arterial elastance ratio as a reflection of ventricular-vascular coupling. A secondary endpoint associates these periprocedural changes in cardiac mechanoenergetics with functional status at 1 month and 1 year. Conclusions This prospective study aims to elucidate the fundamental changes in cardiac and hemodynamic physiology during contemporary transcatheter valvular interventions.

Ambulatory Pulmonary Artery Pressures After Transcatheter Edge-to-Edge Repair of the Mitral Valve in Patients With Heart Failure and Mitral Regurgitation. Am J Cardiol 2022; 184:90-95.

Abstract
The objective of this study was to assess ambulatory hemodynamics after transcatheter edge-to-edge repair (TEER) of the mitral valve. Pulmonary artery pressure (PAP) measurements from implanted sensors were collected through a remote monitoring database and linked to Medicare fee-for-service claims data. Among patients with linked data, those undergoing TEER were included if the ambulatory PAP monitor was implanted ≥3 months before TEER and ≥3 months of PAP data after TEER were available. The primary end point was diastolic PAP (dPAP) at 3 months after TEER compared with baseline. A total of 50 patients undergoing TEER between July 2014 and March 2020 were included, with an average age of 75 ± 8 years and 70% were men. dPAP was significantly lower at 3 months after TEER than baseline, -1.8 ± 4.8 mm Hg, p = 0.010. The cumulative reduction in dPAP (area under the curve) was significantly lower at 3 months after TEER, 113 ± 267 mm Hg-days, p = 0.004. A reduction in dPAP at 3 months after TEER was independently associated with a significantly lower risk of heart failure hospitalization (p = 0.023). TEER of the mitral valve is associated with a clinically relevant and sustained reduction in dPAP.

Abstract
Acute mitral regurgitation (MR) may develop in the setting of an acute myocardial infarction (AMI) because of papillary muscle dysfunction or rupture. Severe acute MR in this scenario is a life-threatening complication associated with hemodynamic instability and pulmonary edema, and has been linked to a worse prognosis even after reperfusion. Patients treated solely with medical therapy have the highest mortality rates. Surgery has been the only treatment strategy until recently, but the results of the technique are hindered by high rates of morbidity and mortality. Therefore, the development of less invasive interventions for correcting MR would be ideal. We aimed to review the current role of transcatheter interventions in this clinical setting.

Incidence and Predictors of New-Onset Atrial Fibrillation After Transcatheter Edge-to-Edge Repair of the Mitral Valve (from the Nationwide Readmissions Database). Am J Cardiol 2022; 182:55-62.

Abstract
Patients who underwent transcatheter edge-to-edge repair (TEER) for mitral regurgitation with atrial fibrillation (AF) at baseline have higher mortality than those without AF. Data on new-onset AF (NOAF) after TEER are limited. Using the 2016 to 2018 Nationwide Readmissions Database, we identified a cohort of patients who underwent TEER and classified them into 3 groups based on AF presence during the study period. The primary end point was the incidence and timing of NOAF up to 6 months after TEER. Logistic regression modeling identified independent predictors of NOAF at readmission. Of the 6,861patients that underwent TEER, 4,134 (59.9%) had AF at baseline, and 239 (3.5%) developed NOAF. Median time-to-NOAF admission was 47 days (interquartile range 16 to 113), and 37% of patients with NOAF presented within 30 days after TEER. Patients with NOAF experienced costlier and longer index-TEER hospitalization and had more co-morbidities. Chronic kidney disease (odds ratio [OR] 1.51, 95% confidence interval [CI] 1.03 to 2.20), fluid and electrolyte disorders (OR 1.59, 95% CI 1.01 to 2.52), and heart failure (OR 1.86, 95% CI 1.01 to 3.44) were identified as independent predictors of NOAF. Hypertensive complications and heart failure were the leading causes of readmission. In conclusion, those patients that developed NOAF after TEER tended to be an overall sicker group at baseline compared with the remainder of the study cohort. These data, obtained from a nationally representative cohort, highlight a particular group of patients subject to developing NOAF and their association with increased rehospitalization in the post-TEER setting. Predictors of NOAF can be screened for during TEER workup to identify patients at increased risk.

Abstract
Left ventricular (LV) myocardial work (LVMW) indexes have shown incremental value over LV ejection fraction and were found to have prognostic significance in patients with secondary mitral regurgitation. We therefore aimed to investigate the association between LVMW indexes and forward flow reserve in patients with secondary mitral regurgitation, treated with transcatheter edge-to-edge repair (TEER). LVMW indexes were evaluated at baseline and forward stroke volume index (FSVI) was evaluated at baseline and 6-month follow-up after TEER. Patients were divided in 2 groups: improvers (improvement in FSVI ≥20%) and nonimprovers (improvement in FSVI <20%). A total of 70 patients (median age 76 years, 59% men) were included. FSVI was the only echocardiographic parameter that improved after TEER. There was a significant decrease in LV global longitudinal strain in the nonimprovers (p = 0.002) but not in the improvers (p = 0.177). Global work index and global constructive work worsened in nonimprovers (p = 0.005 and p = 0.004, respectively), whereas no difference was seen in these indexes in improvers (p = 0.093 and p = 0.112, respectively). Global work efficiency remained independently associated with forward flow reserve after adjusting for a variety of potential confounders. In conclusion, FSVI nonimprovers demonstrated worsening of LV systolic function after TEER compared with improvers, in whom LV systolic function remained stable. Global work efficiency was associated with FSVI improvement after TEER, independent of LV systolic function.

Rescue transventricular off-pump mitral valve repair with artificial neochords for acute mitral regurgitation due to postinfarction papillary muscle rupture. JTCVS Tech 2021; 10:231-242.

Abstract
BACKGROUND We report 3 cases of rescue transventricular off-pump mitral valve (MV) repair in high-risk patients with acute mitral regurgitation (MR) due to post-myocardial infarction (MI) papillary muscle rupture (PMR). METHODS The 3 patients presented with acute inferior ST elevation myocardial infarction, cardiogenic shock, and pulmonary edema. Their preoperative peak troponin I levels were 1909 ng/L, 16,963 ng/L, and 8299 ng/L. All 3 patients underwent successful percutaneous intervention to the culprit coronary artery, and antiplatelet therapy was initiated. All patients required inotropic support and had an intra-aortic balloon pump inserted preoperatively. Transesophageal echocardiography (TEE) demonstrated severe eccentric MR due to the leaflet prolapse secondary to PMR. The patients' estimated EuroSCORE II scores were 16.03%, 16.68%, and 7.81%, and their Society of Thoracic Surgeons scores were 14.77%, 18.24%, and 9.8%, respectively. All 3 patients underwent urgent transventricular off-pump MV repair using artificial chords, with 2 or 3 three neochords implanted. The duration of operation was <2 hours, and intraoperative and postoperative drainage was minimal in all cases. MV function was assessed by qualitative and semiquantitative TEE. RESULTS Intraoperative MR reduction to a mild level was achieved in all 3 patients. All patients had moderate MR at discharge, likely due to left ventricular remodeling. Severe MR recurred in all patients, at 5, 4, and 2 months of follow-up, respectively. All 3 patients underwent an elective MV reoperation via conventional approach. CONCLUSIONS Off-pump transventricular MV repair may offer a safe and feasible alternative to stabilize high-risk patients with acute MR due to post-MI PMR. Although early MR recurrence is concerning, urgent transventricular MV repair may serve as a bridge to conventional surgery in such unstable patients.

Abstract
Background The change in right-ventricular function (RVF) after transcatheter mitral valve repair is still poorly understood. We assessed the early response of RVF to the MitraClip procedure and its clinical relevance. Methods We analyzed consecutive patients who underwent a MitraClip procedure to treat MR between August 2010 and March 2019 in the Heart Failure Network Rhineland registry. RVF was assessed before and after the procedure. Impaired RVF was defined as an RV fractional area change (RVFAC) < 35% or tricuspid annular plane systolic excursion (TAPSE) < 16 mm. Results 816 eligible patients (77 ± 9 years, 58.5% male) were included in the analysis. Baseline values of RVF were: RVFAC 38.6 (IQR 29.7–46.7) % and TAPSE 17.0 (IQR 14.0–21.0) mm. At a median time of 3 (IQR 2–5) days after the procedure, the RVF remained normal in 34% (n = 274), normalized in 17% (n = 140), deteriorated in 15% (n = 125), and was persistently impaired in 34% (n = 277) of patients. The RVF response was significantly associated with a composite outcome of all-cause mortality and hospitalization due to heart failure within a 2-year follow-up. Compared to stable/normal RVF, the adjusted hazard ratios for the outcome were 1.78 (95% CI 1.10–2.86) for normalized RVF, 1.89 (95% CI 1.34–3.15) for deteriorated RVF, and 2.25 (95% CI 1.47–3.44) for persistently impaired RVF. Changes in TAPSE and RVFAC as continuous variables were significantly correlated with the outcome. Conclusion An early change in RVF following transcatheter mitral valve repair is predictive of mortality and hospitalization due to heart failure during follow-up. Graphic abstract Early response of RVF after MitraClip and its clinical significance. An acute, early change in RVF can be observed following the MitraClip procedure, which is associated with the risk of mortality and hospitalization for HF. ![]()

Impact of Post-Procedural Change in Left Ventricle Systolic Function on Survival after Percutaneous Edge-to-Edge Mitral Valve Repair. J Clin Med 2021; 10:jcm10204748. [PMID: 34682871 PMCID: PMC8537749 DOI: 10.3390/jcm10204748] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/10/2021] [Accepted: 10/13/2021] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVES To investigate how the changes of left ventricle ejection fraction (LVEF) between admission and discharge affected the long-term outcome in patients who underwent percutaneous edge-to-edge mitral valve repair for secondary mitral regurgitation. BACKGROUND An acute impairment of LVEF after surgical repair of mitral regurgitation, known as afterload mismatch, has been associated with increased all-cause mortality. Afterload mismatch after percutaneous edge-to-edge mitral valve repair has been postulated to be a transient phenomenon. METHODS This study is based on a single-center, retrospective, observational registry of patients who underwent percutaneous edge-to-edge mitral valve repair with the MitraClip (Abbot Vascular) system for the treatment of symptomatic, moderate-to-severe mitral regurgitation. We included data on 399 patients who underwent percutaneous edge-to-edge mitral valve repair for secondary mitral regurgitation. Expert echocardiographers assessed LVEF before the procedure and at discharge. The patients were divided into three groups according to the difference of periprocedural LVEF measurements: unchanged (n = 318), improved (n = 40), and decreased (n = 41) LVEF. RESULTS The median follow-up time was 2.0 years. When adjusted for gender, NYHA class and estimated glomerular filtration rate, decreased postprocedural LVEF was associated with an increased risk of death (adjusted HR 2.05, 95% CI 1.26-3.34) and increased postprocedural LVEF with a reduced risk of death (adjusted HR 0.47, 95% CI 0.24-0.91) compared to unchanged LVEF. Conclusion: Among patients who underwent percutaneous edge-to-edge mitral valve repair, decreased postprocedural LVEF was associated with increased mortality, while improved LVEF was associated with lower mortality compared to unchanged LVEF.

Abstract
Aims Changes in peak exercise oxygen uptake (VO2) and cardiac output (CO) 6 months after successful percutaneous edge‐to‐edge mitral valve repair (pMVR) in severe primary (PMR) and functional mitral regurgitation (FMR) patients are unknown. The aim of the study was to assess the efficacy of pMVR at rest by echocardiography, VO2 and CO (inert gas rebreathing) measurement and during cardiopulmonary exercise test with CO measurement. Methods and results We evaluated 145 and 115 patients at rest and 98 and 66 during exercise before and after pMVR, respectively. After successful pMVR, significant reductions in MR and NYHA class were observed in FMR and PMR patients. Cardiac ultrasound showed reverse remodelling (left ventricular end‐diastolic volume from 158 ± 63 mL to 147 ± 64, P < 0.001; ejection fraction from 51 ± 15 to 48 ± 14, P < 0.001; pulmonary artery systolic pressure (PASP) from 43 ± 13 to 38 ± 8 mmHg, P < 0.001) in the entire population. These changes were significant in PMR (n = 62) and a trend in FMR (n = 53), except for PASP, which decreased in both groups. At rest, CO and stroke volume (SV) increased in FMR with a concomitant reduction in arteriovenous O2 content difference [ΔC(a‐v)O2]. Peak exercise, CO and SV increased significantly in both groups (CO from 5.5 ± 1.4 L/min to 6.3 ± 1.5 and from 6.2 ± 2.4 to 6.7 ± 2.0, SV from 57 ± 19 mL to 66 ± 20 and from 62 ± 20 to 69 ± 20, in FMR and PMR, respectively), whereas peak VO2 was unchanged and ΔC(a‐v)O2 decreased. Conclusions These data confirm pMVR‐induced clinical improvement and reverse ventricular remodelling at a 6‐month analysis and show, in spite of an increase in CO, an unchanged exercise performance, which is achieved through a ‘more physiological’ blood flow distribution and O2 extraction behaviour. Direct rest and exercise CO should be measured to assess pMVR efficacy.

Abstract
Transcatheter edge-to-edge mitral valve repair is a minimally invasive treatment option for selected patients with moderate to severe or severe mitral regurgitation. Although transcatheter edge-to-edge mitral valve repair offers a significant step forward in the management of mitral regurgitation, the rate of procedural-related complications is not trivial. High-quality periprocedural imaging is important for optimal patient selection and procedural success. In this review, we present a step-by-step approach of the recommended echocardiographic views for transcatheter edge-to-edge mitral valve repair.

Abstract
Background Edge‐to‐edge transcatheter mitral valve repair as salvage therapy in high surgical risk patients with severe mitral regurgitation presenting with cardiogenic shock (CS) has been described in small case series, but large clinical results have not been reported. This study aimed to evaluate outcomes of transcatheter mitral valve repair with MitraClip in patients with mitral regurgitation and CS using a large national database. Methods and Results From January 2014 to March 2019, we identified hospitalizations for CS in patients with mitral valve disease using data from Centers for Medicare and Medicaid Services. Those with a prior surgical or percutaneous mitral valve intervention were excluded. We compared survival between patients who underwent MitraClip during the index hospitalization and those who did not using propensity‐matched analysis. The analysis included 38 166 patients (mean age, 71±11 years, 41.6% women) of whom 622 (1.6%) underwent MitraClip. MitraClip was increasingly used during CS hospitalizations over the study period (P<0.001). After matching, patients receiving MitraClip had significantly lower in‐hospital mortality (odds ratio, 0.6; 95% CI, 0.47–0.77; P<0.001) and 1‐year mortality (hazard ratio, 0.76; 95% CI, 0.65–0.88; P<0.001) compared with those without MitraClip. The survival benefit associated with MitraClip was consistent across subgroups of interest, with the exception of patients requiring acute mechanical circulatory support or hemodialysis at index. Conclusions In patients with mitral regurgitation presenting with CS, use of MitraClip is increasing and associated with greater in‐hospital and 1‐year survival. Further studies are warranted to optimize patient selection and procedure timing for those receiving MitraClip as a treatment option in CS.

Abstract
BACKGROUND The aim of this study was to clarify the clinical outcomes of patients with atrial functional mitral regurgitation (FMR) who underwent the MitraClip procedure compared with those with conventional FMR and sinus rhythm (SR).Methods and Results:Of 303 patients with FMR who underwent the MitraClip procedure, 40 with "atrial-FMR" defined as FMR with permanent atrial fibrillation and normal left ventricular (LV) function/size and 115 with "sinus-FMR" defined as FMR with SR and LV dysfunction were reviewed. Transthoracic and 3D transesophageal echocardiography, and the cardiac complication rate (composite of all-cause death, heart failure admission, mitral valve (MV) surgery, and redo MitraClip procedure) during the 12-month follow-up were compared between the groups. After the MitraClip procedure, reductions in the mitral annular area and its anteroposterior dimension and in the leaflet closure area were observed in both groups. MV orifice area was smaller with greater transmitral pressure gradient (P<0.05) after the procedure in atrial-FMR patients than in those with sinus-FMR. The prevalence of residual MR was similar, but significant tricuspid regurgitation (TR) was more prevalent in the atrial-FMR group at follow-up. Cardiac complication rate was comparable between groups (20% vs. 25%, P=0.63). CONCLUSIONS Reduction of MR occurred in atrial-FMR probably because of the increase in leaflet coaptation area. Significant TR was more common after the MitraClip procedure in patients with atrial-FMR than with sinus-FMR. However, mid-term outcomes were comparable between patients with atrial-FMR and sinus-FMR.

Abstract
OBJECTIVES To assess outcomes in patients with acute mitral regurgitation (MR) following acute myocardial infarction (AMI) who received percutaneous mitral valve repair (PMVR) with the MitraClip device and to compare outcomes of patients who developed cardiogenic shock (CS) to those who did not (non-CS). BACKGROUND Acute MR after AMI may lead to CS and is associated with high mortality. METHODS This registry analyzed patients with MR after AMI who were treated with MitraClip at 18 centers within eight countries between January 2016 and February 2020. Patients were stratified into CS and non-CS groups. Primary outcomes were mortality and rehospitalization due to heart failure. Secondary outcomes were acute procedural success, functional improvement, and MR reduction. Multivariable Cox regression analysis evaluated association of CS with clinical outcomes. RESULTS Among 93 patients analyzed (age 70.3 ± 10.2 years), 50 patients (53.8%) experienced CS before PMVR. Mortality at 30 days (10% CS vs. 2.3% non-CS; p = .212) did not differ between groups. After median follow-up of 7 months (IQR 2.5-17 months), the combined event mortality/re-hospitalization was similar (28% CS vs. 25.6% non-CS; p = .793). Likewise, immediate procedural success (90% CS vs. 93% non-CS; p = .793) and need for reintervention (CS 6% vs. non-CS 2.3%, p = .621) or re-admission due to HF (CS 13% vs. NCS 23%, p = .253) at 3 months did not differ. CS was not independently associated with the combined end-point (hazard ratio 1.1; 95% CI, 0.3-4.6; p = .889). CONCLUSIONS Patients found to have significant MR during their index hospitalization for AMI had similar clinical outcomes with PMVR whether they presented in or out of cardiogenic shock, provided initial hemodynamic stabilization was first achieved before PMVR.

Abstract
Cardiac hypertrophy, defined as an increase in mass of the heart, is a complex process driven by simultaneous changes in hemodynamics, mechanical stimuli, and hormonal inputs. It occurs not only during pre- and post-natal development but also in adults in response to exercise, pregnancy, and a range of cardiovascular diseases. One of the most exciting recent developments in the field of cardiac biomechanics is the advent of computational models that are able to accurately predict patterns of heart growth in many of these settings, particularly in cases where changes in mechanical loading of the heart play an import role. These emerging models may soon be capable of making patient-specific growth predictions that can be used to guide clinical interventions. Here, we review the history and current state of cardiac growth models and highlight three main limitations of current approaches with regard to future clinical application: their inability to predict the regression of heart growth after removal of a mechanical overload, inability to account for evolving hemodynamics, and inability to incorporate known growth effects of drugs and hormones on heart growth. Next, we outline growth mechanics approaches used in other fields of biomechanics and highlight some potential lessons for cardiac growth modeling. Finally, we propose a multiscale modeling approach for future studies that blends tissue-level growth models with cell-level signaling models to incorporate the effects of hormones in the context of pregnancy-induced heart growth.

Insufficient Mitral Leaflet Remodeling in Relation to Annular Dilation and Risk of Residual Mitral Regurgitation After MitraClip Implantation. JACC Cardiovasc Imaging 2020; 14:756-765. [PMID: 33129743 DOI: 10.1016/j.jcmg.2020.08.019] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 08/17/2020] [Accepted: 08/19/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVES The purpose of this study was to determine whether the mitral valve (MV) total leaflet area (TLA)-to-mitral annular area (MAA) (TLA/MAA) ratio measured using 3-dimensional (3D) transesophageal echocardiography (TEE) was associated with residual mitral regurgitation (MR) after MitraClip implantation in patients with secondary MR. BACKGROUND The factors influencing the results of MitraClip implantation for secondary MR are controversial. This study hypothesized that insufficient remodeling of the mitral leaflets relative to the annular dilation may be associated with significant MR after MitraClip implantation. METHODS This study included patients with secondary MR treated with MitraClips. Using 3D TEE dataset, the TLA in diastole and MAA in systole were measured with dedicated software. RESULTS In a total cohort of 119 patients (mean age 74 ± 9 years; 61% male), significant residual MR (≥2+) was present in 43 patients (36%). In patients with significant residual MR, MAA was greater than in patients without residual MR (10.7 ± 2.4 cm2 vs. 9.0 ± 2.1 cm2; p < 0.001) whereas no significant difference was observed in TLA (12.2 ± 2.6 cm2 vs. 12.0 ± 2.9 cm2; p = 0.836). TLA/MAA ratio was lower in patients with significant residual MR as compared to their counterparts (1.14 ± 0.15 vs. 1.34 ± 0.16; p < 0.001), suggesting insufficient leaflet remodeling relative to annular dilation. On receiver-operating characteristic curve analysis, the TLA/MAA ratio had better discriminative power to identify patients who will have significant residual MR compared to MAA alone (area under the curve [AUC]: 0.830 vs. 0.723; p = 0.049). CONCLUSIONS In patients with secondary MR, insufficient mitral leaflet remodeling relative to the annulus dilation, as reflected by a lower TLA/MAA ratio, is associated with significant residual MR after MitraClip implantation.

Eden M, Leeb L, Frey N, Rosenberg M. Haemodynamics of an iatrogenic atrial septal defect after MitraClip implantation. Eur J Clin Invest 2020; 50:e13295. [PMID: 32474906 DOI: 10.1111/eci.13295] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 05/01/2020] [Accepted: 05/23/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND The MitraClip procedure requires transseptal access of the left atrium with a 24F guiding sheath. We evaluated invasively whether a MitraClip induced iatrogenic atrial septal defect (IASD) leads to development of a relevant interatrial shunt and right ventricular overload. METHODS A total of 69 patients who underwent a MitraClip procedure due to a severe mitral valve regurgitation (MVR) were included in the observational, retrospective cohort study. All pressures were directly measured throughout the procedure. Cardiac index (CI), systemic (Qs) and pulmonary (Qp) flow were calculated using the Fick method. RESULTS Successful MitraClip implantation increased CI (2.5 ± 0.62 vs 3.05 ± 0.77 L/min/m2 ; P < .0001), whereas SVR (1491 ± 474 vs 997 ± 301 dyn s/cm5 ; P < .0001), PVR (226 ± 121 vs 188 ± 96 dyn/s/cm5 ; P = .04), PCWP (23 ± 6.1 vs 20 ± 4.7 mm Hg; P = .0031), PA pressure (33.6 ± 7.2 vs 31.9 ± 6.6 mm Hg; P = .1437) and LA pressure (21.5 ± 5.4 vs 18.7 ± 4.9 mm Hg; P < .0001) all decreased. The effect on LA pressure was further enhanced by guiding catheter retrieval (14.4 ± 4.6 mm Hg; P < .0001). At the end of the procedure, Qp (6.033 ± 1.3 L/min) exceeded Qs (5.537 ± 1.3 L/min) by 0.496 L/min leading to a Qp:Qs ratio of 1.09 (P = .007). After 6 months, echocardiography revealed no changes in RV diameter (42.96 ± 6.95 mm vs 43.81 ± 7.67 mm; P = .62) and TAPSE (17.13 ± 3.33 mm vs 17.36 ± 3.24 mm; P = .48). CONCLUSION Our data show that the MitraClip procedure does not induce a relevant interatrial shunt or right ventricular overload. In fact, future studies will have to show whether the IASD may even be beneficial in selected patient populations by left atrial volume and pressure relief.

Abstract
INTRODUCTION Percutaneous mitral valve repair with MitraClip device has been approved for treatment of mitral regurgitation in symptomatic patients deemed high risk for surgical repair. This study compares outcomes of Mitraclip in patients with systolic (SHF) versus diastolic heart failure (DHF). METHODS The study population was extracted from the 2016 Nationwide Readmissions Data (NRD) using International Classification of Diseases, tenth edition, clinical modifications/procedure coding system (ICD-9-CM/PCS) codes for the Mitraclip, SHF, DHF, and procedural complications. Study endpoints included in-hospital all-cause mortality, cardiogenic shock, acute myocardial infarction (AMI), acute kidney injury (AKI), stroke, acute respiratory failure, bleeding, blood transfusion, length of hospital stay (LOS) as well as 30-day readmission rate. RESULTS A total of 1681 discharges that had Mitraclip during the index hospitalization and had a history of SHF (909) or DHF (772) were included in this analysis. The mean age was 78.5 years and 46.6% were female. SHF group was associated with higher post-procedural cardiogenic shock (7.3% versus 2.0%, p < 0.01), AMI (2.1% versus 0.8%, p = 0.03), AKI (21.0 versus 14.2%, p < 0.01), acute respiratory failure (13.2% versus 9.6%, p = 0.02), and longer LOS (9.6 versus 5.7 days, p < 0.01). There were no significant differences between groups in terms of in-hospital all-cause mortality (3.4% versus 2.3%, p = 0.18), stroke (0.7% versus 1.4%, p = 0.15), bleeding (10.7% versus 8.9%, p = 0.23), need for blood transfusion (5.7% versus 3.6%, p = 0.05), or 30-day readmission rate (15.7% versus 16.1%, p = 0.86). CONCLUSIONS In comparison to DHF, patients with SHF undergoing the MitraClip had higher in-hospital morbidities and longer LOS but comparable mortality and 30-day readmission rates.

Abstract
Mitral valvulopathy presents as regurgitation, stenosis, or mixed disease and can occur in both native and prosthetic valves. Such disease develops in conjunction with pathophysiologic changes in the left atrium (LA) and drives changes in LA compliance, pressure, and thus clinical syndromes. With advances in the understanding and treatment of structural heart disease and in the setting of higher-risk patient populations, less-invasive transcatheter approaches have become increasingly commonplace in the treatment of mitral valve disease. Over time, transcatheter mitral valve interventions have evolved to include paravalvular leak closure, mitral valve repair, and mitral valve replacement. Parallel to this evolution, advances in invasive intracardiac pressure monitoring, particularly at the level of the LA, have also occurred. These advances emphasize the unique interplay between mitral valve disease and LA function; account for limitations of noninvasive assessment; and guide beneficial outcomes in each area of transcatheter mitral valve intervention. As a result, continuous transseptal LA pressure monitoring has developed into an indispensable instrument in successful percutaneous mitral valve intervention, complementing traditional noninvasive assessment.

Abstract
Secondary (also known as functional) mitral regurgitation (MR) has increased substantially over the last several decades due to an increase in the prevalence of dilated cardiomyopathy (ischemic and non-ischemic). Mortality and morbidity in patients with dilated cardiomyopathy is much greater when associated with MR as compared to without MR. MR will result in further left ventricular (LV) volume overload, LV dilation, and pupillary muscle displacement resulting in deterioration of the severity of MR leading to a vicious cycle. Optimization of heart failure medical therapy, and cardiac resynchronization therapy for those that qualify, can improve severity of MR; however, significant MR will persist in certain patients. Transcatheter mitral valve repair to treat significant MR using the MitraClip (Abbott, Menlo Park, California), which grasps and coapts the posterior and anterior mitral valve leaflets, in appropriately selected patients with dilated cardiomyopathy and secondary MR has been shown to improve quality of life and prolong survival.

Abstract
Although mitral regurgitation (MR) is the most common valvular heart disease, it should be regarded as a complex multifactorial disease that involves multiple entities. Optimal medical therapy alone does not hinder the progression of the disease, and in the 1980s it was already recognised that corrective surgery is indicated if MR is severe and patients are symptomatic (except for those with the most severe left ventricle dysfunction). Later on, asymptomatic patients with deterioration of the left ventricular ejection fraction were also operated on to avoid irreversible left ventricular dysfunction, heart failure and eventually death. However, a major drawback remains the fact that a significant group of patients is considered to have a high perioperative risk due to their advanced age or severe comorbidities. Since less invasive, percutaneous interventions have been developed and recently thoroughly investigated in the MITRA-FR and the COAPT studies, the type of intervention and also the timing have become more crucial. In this critical review of the literature, we describe what we should have learned from the past and which (haemodynamic) parameters can best predict the outcome in patients with MR.

Abstract
The goal of this study was to determine the predictors of adverse clinical outcomes in patients treated with the MitraClip for significant mitral regurgitation (MR) with a focus on acute changes in hemodynamics and cardiac function. This retrospective study included 63 patients (mean age 82 ± 8 years, 48% male) with moderate to severe or severe MR. Cardiac catheterization was performed before and immediately after MitraClip repair. Volumetric and functional changes were assessed in both ventricles. A major adverse cardiac event was defined as a composite of cardiac death and readmission for heart failure. Patients were followed up on average for 380 days. MR was improved in 92% of patients after MitraClip therapy from an average grade of 4+ to <2+ (p <0.001). The pulmonary capillary wedge pressure decreased from 22 ± 7 mm Hg to 19 ± 6 mm Hg (p <0.001), and the cardiac stroke volume increased by 28% from 102 ± 53 ml to 131 ± 54 ml (p <0.001). The left ventricular end-diastolic volume was significantly reduced 24 hours after MitraClip therapy compared to that at baseline (p = 0.001). In the multivariate Cox proportion hazard regression model, an age ≥85 years (p <0.001) and residual MR >1+ (p <0.048) were predictors of an adverse prognosis at follow-up. In conclusion, a reduced left ventricular end-diastolic volume and improved hemodynamics occurred early after MitraClip therapy. An advanced age (≥85 years) and residual MR >1+ were associated with an increased risk of mortality and heart failure.

Abstract
Introduction In this study, we evaluated right ventricular (RV) function before and after percutaneous mitral valve repair (PMVR) using conventional echocardiographic parameters and novel 3DE data sets acquired prior to and directly after the procedure. Patients and methods Observational study on 45 patients undergoing PMVR at an university hospital. Results In the overall collective, the 3D RV-EF before and after PMVR showed no significant change (p = 0.16). While there was a significant increase of the fractional area change (FAC, from 23 [19–29] % to 28 [24–33] %, p = 0.001), no significant change of the tricuspid annular plane systolic excursion (TAPSE, from 17 ± 6 mm to 18 ± 5 mm (standard deviation), p = 0.33) was observed. Regarding patients with a reduced RV-EF (< 35%), a significant RV-EF improvement was observed (from 27 [23–34] % to 32.5 [30–39] % (p = 0.001). 71.4% of patients had an improved clinical outcome (improvement in 6-minute walk test and/or improvement in NYHA class of more than one grade), whereas clinical outcome did not improve in 28.6% of patients. Using univariate logistic regression analysis, the post-PMVR RV-EF (OR 1.15: 95% CI 1.02–1.29; p = 0.02) and the change in RV-EF (OR 1.13: 95% CI 1.02–1.25; p = 0.02) were significant predictors for improved clinical outcome at 6 months follow up. Conclusion Thus, RV function may be an important non-invasive parameter to add to the predictive parameters indicating a potential clinical benefit from treatment of severe mitral regurgitation using PMVR.

Abstract
Surgery has been the standard of care for mitral valve diseases to date. In the last fifteen years, due to increased aging of the population, with a great number of patients being high-risk for surgical treatment, transcatheter treatments for mitral valve disease have greatly developed. Further development and expansion of transcatheter treatments are expected. However, some limitations remain, such as efficacy and durability, which impact the widespread use of these devices.

Abstract
BACKGROUND Functional mitral regurgitation (FMR) is a common finding among patients with heart failure (HF) and it is related to adverse events. Outcomes in patients undergoing transcatheter mitral valve repair (TMVR) are still a matter of debate. We performed a meta-analysis to assess mid- and long-term outcomes of patients with FMR treated with MitraClip® compared to medical management. METHODS We conducted an electronic database search of all published data PubMed Central, Embase, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and Google Scholar databases. The primary end-point was all-cause mortality. The secondary end-points were hospitalizations for HF, need for heart transplantation or left ventricular assist device, unplanned mitral valve surgery, myocardial infarction and stroke. RESULTS Five studies (n = 1513 patients) were included in the analysis. The summary estimate including all the available studies showed a statistically significant reduction in all-cause mortality favoring MitraClip® (HR 0.56, CI 95% [0.38-0.84]) and HF hospitalizations (HR 0.65; CI 95% [0.46-0.92]). A significant reduction in the indication for advanced HF therapies (OR 0.48; CI 95% [0.25-0.90]) or the need for unplanned mitral valve surgery (OR 0.20; CI 95% [0.07-0.57]) was also found in the group of patients that underwent TMVR. No differences in the incidence of myocardial infarction or stroke were found between both groups of treatment. No publication bias was detected. CONCLUSION TMVR with MitraClip® system was related to a significant reduction in all-cause mortality, hospitalizations for HF and the need for HF transplant, left ventricular assist device or unplanned surgery beyond 1-year follow up.

Abstract
Background This study analyzed the effects on long-term outcome of residual mitral regurgitation ( MR ) and mean mitral valve pressure gradient ( MVPG ) after percutaneous edge-to-edge mitral valve repair using the MitraClip system. Methods and Results Two hundred fifty-five patients who underwent percutaneous edge-to-edge mitral valve repair were analyzed. Kaplan-Meier and Cox regression analyses were performed to evaluate the impact of residual MR and MVPG on clinical outcome. A combined clinical end point (all-cause mortality, MV surgery, redo procedure, implantation of a left ventricular assist device) was used. After percutaneous edge-to-edge mitral valve repair, mean MVPG increased from 1.6±1.0 to 3.1±1.5 mm Hg ( P<0.001). Reduction of MR severity to ≤2+ postintervention was achieved in 98.4% of all patients. In the overall patient cohort, residual MR was predictive of the combined end point while elevated MVPG >4.4 mm Hg was not according to Kaplan-Meier and Cox regression analyses. We then analyzed the cohort with degenerative and that with functional MR separately to account for these different entities. In the cohort with degenerative MR , elevated MVPG was associated with increased occurrence of the primary end point, whereas this was not observed in the cohort with functional MR . Conclusions MVPG >4.4 mm Hg after MitraClip implantation was predictive of clinical outcome in the patient cohort with degenerative MR . In the patient cohort with functional MR , MVPG >4.4 mm Hg was not associated with increased clinical events.

Abstract
Percutaneous mitral valve repair is emerging as a reasonable alternative especially in those with an unfavorable surgical risk profile in the repair of mitral regurgitation. At this time, our understanding of the effects of underlying renal dysfunction on outcomes with percutaneous mitral valve repair and the effects of this procedure itself on renal function is evolving, as more data emerges in this field. The current evidence suggests that the correction of mitral regurgitation via percutaneous mitral valve repair is associated with some degree of improvement in cardiac function, hemodynamics and renal function. The improvement in renal function was more significant for those with greater renal dysfunction at baseline. The presence of Chronic Kidney Disease (CKD) in turn has been associated with poor long-term outcomes including increased mortality and hospitalization among patients who undergo percutaneous mitral valve repair. This was true regardless of the degree of improvement in GFR post repair advanced CKD. The adverse impact of CKD on long-term outcomes was consistent across all studies and was more prominent in those with GFR<30 mL/min/1.73 m². It is clear that from these contrasting evidences of improved renal function post mitral valve repair but poor long-term outcomes including increased mortality in patients with CKD, that proper patient selection for percutaneous mitral valve repair is key. There is a need to have better-standardized criteria for patients who should qualify to have percutaneous mitral valve replacement with Mitraclip. In this new era of percutaneous mitral valve repair, much work needs to be done to optimize long-term patient outcomes.

Abstract
Aims Improved mitral valve leaflet coaptation with consecutive reduction of mitral regurgitation (MR) is a central goal of percutaneous mitral valve repair (PMVR) with the MitraClip® system. As influences of PMVR on mitral valve geometry have been suggested before, we examined the effect of the procedure on mitral annular size in relation to procedural outcome. Methods and results Geometry of the mitral valve annulus was evaluated in 183 patients undergoing PMVR using echocardiography before and after the procedure and at follow-up. Mitral valve annular anterior-posterior (ap) diameter decreased from 34.0 ± 4.3 to 31.3 ± 4.9 mm (P < 0.001), and medio-lateral (ml) diameter from 33.2 ± 4.8 to 32.4 ± 4.9 mm (P < 0.001). Accordingly, we observed an increase in MV leaflet coaptation after PMVR. The reduction of mitral valve ap diameter showed a significant inverse correlation with residual MR. Importantly, the reduction of mitral valve ap diameter persisted at follow-up (31.3 ± 4.9 mm post PMVR, 28.4 ± 5.3 mm at follow-up). Conclusion This study demonstrates mechanical approximation of both mitral valve annulus edges with improved mitral valve annular coaptation by PMVR using the MitraClip® system, which correlates with residual MR in patients with MR.
