A Novel Hemodynamic Index Characterizing Mitral Regurgitation Undergoing Transcatheter Edge-to-Edge Repair: The MPF. JACC. ADVANCES 2024; 3:101099. [PMID: 39105121 PMCID: PMC11299577 DOI: 10.1016/j.jacadv.2024.101099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 12/12/2023] [Accepted: 01/23/2024] [Indexed: 08/07/2024]
Abstract
Background Hemodynamic impact of residual mitral regurgitation (MR) after transcatheter edge-to-edge repair (TEER) is not always univocally measured by transesophageal echocardiographic (TEE) assessment alone. When analyzing TEER procedure result, operators often encounter discrepancy between TEE guidance and invasive hemodynamic monitoring. Objectives This study sought to investigate the role of invasive hemodynamic monitoring during mitral valve TEER procedure on top of TEE guidance. Methods We analyzed 78 patients with moderate-to-severe or severe MR who underwent TEER. Mitral pulse pressure fraction (MPF) was extracted from intraprocedural continuous left atrial pressure monitoring. Twenty-three patients with the same grade of MR not undergoing TEER were included as a control group. At follow-up, clinical and functional status in the majority of patients undergoing TEER were reassessed by NYHA classification and the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ). Results TEER significantly reduced MR burden on both TEE guidance and invasive hemodynamic monitoring. Post-TEER MPF was significantly reduced compared to both pre-TEER setting (P < 0.001) and control group (P < 0.001). At follow-up, while MR reduction assessed by TEE was associated with an improved functional status in terms of the 12-item KCCQ but not of NYHA classification, a greater reduction in MPF was associated with a significant amelioration of both NYHA classification (P = 0.036) and 12-item KCCQ (P = 0.032). Conclusions MPF could provide an immediate estimate of the real hemodynamic impact of MR and a prompt prediction of the functional improvement after TEER.

Abstract
Heart failure (HF) and moderate-to-severe mitral regurgitation (MR) with residual elevations in left atrial pressure (LAP) after MitraClip may remain symptomatic and experience subsequent HF readmissions. The V-Wave interatrial shunt system is a permanent interatrial septal implant that shunts blood from the left-to-right atrium and serves to continuously unload the left atrium. Although the V-Wave shunt has previously been studied in patients with HF, the safety and feasibility of its deployment at the time of the MitraClip procedure is unknown. The V-Wave Shunt MitraClip Study (NCT04729933) is an early feasibility study that aims to demonstrate the safety and efficacy of implantation of the V-Wave shunt device at the time of MitraClip procedure. Patients with moderate-to-severe secondary MR with left ventricular ejection fraction 20% to 50% and New York Heart Association functional class III/IV symptoms despite optimal medical therapy, residual mean LAP ≥20 mm Hg after MitraClip, and mean LAP-right atrial pressure difference ≥5 mm Hg are included. The primary safety end point is a composite outcome of all-cause death, stroke, myocardial infarction device embolization, cardiac tamponade, or device-related re-intervention or surgery at 30 days. Patients will be followed up to 5 years. Enrollment is ongoing, with 30-day results expected by the end of 2024. The V-Wave Shunt Mitraclip Study aims to demonstrate the safety and efficacy of the implantation of the V-Wave interatrial shunt device at the time of index MitraClip placement which may serve as an adjunctive method by which continuous left atrial unloading may be achieved.

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.

Pulmonary Vein Flow Morphology After Transcatheter Mitral Valve Edge-to-Edge Repair as Predictor of Survival. J Am Soc Echocardiogr 2024; 37:530-537.

Abstract
BACKGROUND Data on the prognostic factors after mitral valve (MV) transcatheter edge-to-edge repair (TEER; MV-TEER) are limited. Pulsed-wave Doppler interrogation of pulmonary vein flow (PVF) is a convenient method to assess the hemodynamic burden of residual mitral regurgitation (MR), which could be of utility as a predictor of outcomes. METHODS Patients that underwent MV-TEER between May 2014 and December 2021 at our institution were evaluated. Pulmonary vein flow patterns post-MV-TEER were reviewed on the procedural transesophageal echocardiogram and classified as normal (systolic dominant or codominant) or abnormal (systolic blunting or reversal). The PVF pattern was correlated with all-cause mortality at follow-up. RESULTS Two-hundred sixty-five patients had diagnostic PVF post-MV-TEER, with 73 (27.5%) categorized as normal and 192 (72.5%) categorized as abnormal. Patients with abnormal PVF morphology were more likely to have atrial fibrillation (70% vs 42%, P < .001) and greater than moderate residual MR (16% vs 3%, P = .01) and had higher mean left atrial pressure (18.1 ± 5.0 vs 15.9 ± 4.2 mm Hg, P = .002) and left atrial V wave (26.6 ± 8.5 vs 21.4 ± 7.3 mm Hg, P < .001) postprocedure. In multivariable analysis, abnormal PVF morphology post-MV-TEER was independently associated with mortality at follow-up (hazard ratio = 1.70; 95% CI, 1.06-2.74; P = .03) after correction for end-stage renal disease, atrial fibrillation, and residual MR. Results were similar in subgroups of patients with moderate or less and those with mild or less residual MR. CONCLUSIONS Pulmonary vein flow morphology is a simple and objective tool to assess MR severity immediately post-MV-TEER and offers important prognostic information to optimize procedural results. Additional studies are needed to determine whether patients with abnormal PVF pattern post-MV-TEER would benefit from more intensive goal-directed medical therapy postprocedure.

Long-Term Mortality after Transcatheter Edge-to-Edge Mitral Valve Repair Significantly Decreased over the Last Decade: Comparison between Initial and Current Experience from the MiTra Ulm Registry. J Clin Med 2024; 13:2172. [PMID: 38673445 PMCID: PMC11050104 DOI: 10.3390/jcm13082172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/01/2024] [Accepted: 04/05/2024] [Indexed: 04/28/2024] Open
Abstract
(1) Objective: We aimed to assess whether the candidate profile, the long-term outcomes and the predictors for long-term mortality after transcatheter edge-to-edge mitral valve repair (M-TEER) have changed over the last decade; (2) Methods: Long-term follow-up data (median time of 1202 days) including mortality, MACCE and functional status were available for 677 consecutive patients enrolled in the prospective MiTra Ulm registry from January 2010 to April 2019. The initial 340 patients treated in our institution before January 2016 were compared with the following 337 patients; (3) Results: Patients treated after 2016 showed significantly less ventricular dilatation (left ventricular end-systolic diameter of 43 ± 13 mm vs. 49 ± 16 mm, p < 0.007), lower systolic pulmonary pressures (50 ± 15 mmHg vs. 57 ± 21 mmHg, p = 0.01) and a lower prevalence of severe tricuspid regurgitation (27.2% vs. 47.3%, p < 0.001) at baseline than patients treated before 2016. Compared to the cohort treated before 2016, patients treated afterwards showed a significantly lower all-cause 3-year mortality (29.4% vs. 43.8%, p < 0.001) and lower MACCE (38.6% vs. 54.1%, p < 0.001), without differences for MR etiology. While severe tricuspid regurgitation and NYHA class IV remained independently associated with an increased long-term mortality over the last decade, severe left ventricular dilatation (hazard ratio, HR 2.12, p = 0.047) and severe pulmonary hypertension (HR 2.18, p = 0.047) were predictors of long-term mortality only in patients treated before 2016. (4) Conclusions: The M-TEER candidates are currently treated earlier in the course of disease and benefit significantly in terms of a better long-term survival than patients treated at the beginning of the M-TEER era.

Abstract
BACKGROUND Alcohol septal ablation (ASA) is a minimally invasive treatment for drug-refractory obstructive hypertrophic cardiomyopathy. Detailed assessment of pressure changes and predictors of mortality and procedure success are not well defined. METHODS This is a single-center study evaluating pressure changes and predictors of mortality and procedure success in transseptal ASA. Survival analysis and predictors of mortality were assessed using the Kaplan-Meier analysis and Cox regression, respectively. RESULTS A total of 156 patients were included (mean age, 67.3 years; 46.8% women). Left atrial (LA) pressure and left ventricular outflow tract (LVOT) gradient decreased, whereas aortic pulse pressure (PP) increased post-ASA. Patients with lower baseline mean LA pressure ( 82% (gradient change median), and PP increase >19% (PP change median) had superior survival. On Cox univariable regression, baseline mean LA pressure >median (19 mm Hg; hazard ratio [HR], 2.09 [95% CI, 1.05-4.18]; P=0.036), residual LVOT gradient (HR, 1.02 [95% CI, 1.01-1.03]; P=0.003), and LVOT gradient percent reduction median (28 mm Hg; HR, 2.36 [95% CI, 1.17-4.76]; P=0.016), baseline mean LA pressure >median (19 mm Hg; HR, 2.70 [95% CI, 1.33-5.50]; P=0.006), percentage reduction in gradient CONCLUSIONS ASA is associated with an acute decrease in the LVOT gradient and LA pressures and increase in aortic PP. Mean LA pressure, percentage decrease in LVOT gradient, and increase in PP are strong predictors of survival free of all-cause mortality following ASA and are important variables for procedural guidance.

Abstract
Background There are limited data on repeat mitral transcatheter edge-to-edge repair for recurrent significant mitral regurgitation (MR). Methods and Results We conducted a single-center, retrospective analysis of consecutive patients referred to a second mitral transcatheter edge-to-edge repair after a technically successful first procedure. Clinical, laboratory, and echocardiographic measures were assessed up to 1 year after the intervention. The composite of all-cause death or heart failure (HF) hospitalizations constituted the primary outcome. A total of 52 patients (median age, 81 [interquartile range, 76-87] years, 29 [55.8%] men, 26 [50.0%] with functional MR) met the inclusion criteria. MR recurrences were mostly related to progression of the underlying cardiac pathology. All procedures were technically successful. At 1 year, most patients with available records (n=24; 96.0%) experienced improvement in MR severity or New York Heart Association functional class that was statistically significant but numerically modest. Fourteen (26.9%) patients died or were hospitalized due to HF. These were higher-risk cases with predominantly functional MR who mostly underwent an urgent procedure and exhibited more severe HF indices before the intervention, as well as an attenuated 1-month clinical and echocardiographic response. Overall, 1-year course was comparable to that experienced by patients who underwent only a first transcatheter edge-to-edge repair at our institution (n=902). Tricuspid regurgitation of greater than moderate grade was the only baseline parameter to independently predict the primary outcome. Conclusions Repeat mitral transcatheter edge-to-edge repair is feasible, safe, and clinically effective, especially in non-functional MR patients without concomitant significant tricuspid regurgitation.

Abstract
INTRODUCTION Mitral regurgitation (MR) is associated with substantial morbidity and mortality. Within the past 15 years, mitral valve edge-to-edge repair (M-TEER) has developed from an experimental approach to a guideline-recommended, safe, and effective treatment option for patients with severe primary or secondary mitral regurgitation. AREAS COVERED This review covered relevant publications of M-TEER and summarizes the development of M-TEER devices within the last 15 years. It outlines anatomical challenges which drove the evolution of M-TEER devices, provides an overview about the current state of clinical application and research, and offers an outlook into the future of transcatheter mitral valve treatment. EXPERT OPINION The development and refinement of new M-TEER device generations offer the possibility to treat a wide range of mitral valve anatomies. Choosing the best device for the individual anatomic properties of the patients and considering comorbidities is the key to maximized MR reduction, minimalized complication rates, and thus optimized postinterventional prognosis. Independent from prognostic implications, quality of life has become an important patient-centered outcome that can be improved by M-TEER in virtually all patients treated.

The impact of baseline transmitral diastolic mean gradient on left atrial pressure reduction in patients undergoing transcatheter mitral valve edge-to-edge repair. Catheter Cardiovasc Interv 2023; 101:605-609. [PMID: 36718052 DOI: 10.1002/ccd.30577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 12/23/2022] [Accepted: 01/15/2023] [Indexed: 02/01/2023]
Abstract
BACKGROUND Elevated transmitral gradient post transcatheter mitral valve edge-to-edge repair (TEER) has been associated with worse outcomes. Whether an elevated baseline transmitral diastolic mean gradient (MG) ≥5 mmHg is associated with hemodynamic outcomes after TEER is unknown. METHODS A total of 164 consecutive patients undergoing TEER at Mayo Clinic between June 2014 and May 2018 were analyzed in this retrospective study. Baseline demographics, as well as clinical, echocardiographic, and procedural data were obtained. Data on direct left atrial pressure (LAP) before and after TEER were recorded. Logistic regression models were constructed to evaluate the association between preprocedure transmitral diastolic mean gradient (pre-MG) and (1) improvement in LAP following TEER, (2) postprocedure transmitral diastolic mean gradient (post-MG). A decrease in LAP post TEER was considered an improvement in hemodynamic response. Pre-MG was categorized as: ≥5 and <5 mmHg. RESULTS Median age of the cohort was 81.5 years (Q1: 76.3, Q3: 87) and 34% were female. At baseline, median transmitral diastolic MG was 4 mmHg (Q1: 3, Q3: 5) and median LAP was 19 mmHg (Q1:16, Q3: 23.5). In a multivariable model, adjusted for age and sex, patients with pre-MG ≥ 5 mmHg were less likely to see an improvement in LAP post TEER (adjusted odds ratio [aOR]: 0.22, 95% confidence interval [CI]: 0.09, 0.55; p = 0.001) and more likely to have elevated post-MG (aOR; 7.08, 95% CI: 2.93, 17.13; p < 0.001). CONCLUSION Higher pre-MG (≥5 mmHg) was associated with a lower reduction in LAP and higher residual transmitral gradient following TEER suggesting other potential contributors to increased LAP besides mitral regurgitation as a cause of elevated baseline MG.

Abstract
BACKGROUND Limited data exist regarding the performance of the Society of Thoracic Surgeons (STS) risk score among transcatheter mitral edge-to-edge repair (TEER) patients. OBJECTIVE Evaluate STS score accuracy, and the incremental value of post-procedural left atrial pressure (LAP). METHODS A retrospective analysis of TEER patients between 2013 and 2020. Patients were allocated into 3 groups: high (≥8% [n = 298, 31%]), intermediate (4%-8% [n = 318, 33%]), and low (<4% [n = 344, 36%]). Primary outcomes included 1-year mortality or cardiovascular hospitalizations. Cox proportional hazards regression modeling was used to determine the hazard ratio of the primary outcome, and STS score accuracy was assessed by receiver operating characteristic. A spline curve was used to display the relationship between LAP and the primary endpoint. Continuous net reclassification improvement (NRI) was used to determine the incremental value of LAP. RESULTS We included 960 patients, primarily elderly (79 [70-85]), with a median STS risk of 5.6 (3-9). High-risk patients were older (83 [75-89], 81 [74-87], 72 [64-79], p < 0.001), and had more comorbidities compared to intermediate and low-risk groups. Upon Cox regression, STS score (high vs. low: HR 2.5 [1.7-3.8]; Intermediate vs. low: HR 1.8 [1.2-2.7] and LAP HR 1.03 [1.01-1.06], p = 0.007) were associated with the outcome. C statistics analysis revealed low accuracy of the STS score (AUC-0.61 [0.58-0.65, p < 0.001]). Continuous NRI analysis indicated an improvement in risk prediction of 17% (6.9-26.2), p < 0.001. CONCLUSION STS risk score has low accuracy in predicting clinical outcomes after TEER. Adding LAP measurements can improve reclassification and identify those prone to adverse outcomes.

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. [PMID: 36163050 DOI: 10.1016/j.amjcard.2022.08.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/06/2022] [Accepted: 08/29/2022] [Indexed: 11/29/2022]
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.

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. [PMID: 36075754 DOI: 10.1016/j.amjcard.2022.07.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 07/17/2022] [Accepted: 07/18/2022] [Indexed: 11/29/2022]
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
BACKGROUND Mitral transcatheter edge-to-edge repair (MTEER) is an established therapeutic approach for mitral regurgitation (MR). Functional mitral regurgitation originating from atrial myopathy (A-FMR) has been described. OBJECTIVES We sought to assess the clinical, echocardiographic and hemodynamic considerations in A-FMR patients undergoing MTEER. METHODS From 2014 to 2020, patients undergoing MTEER for degenerative MR (DMR), functional MR (FMR), and mixed MR were assessed. A-FMR was defined by the presence of MR > moderate in severity; left ventricular (LV) ejection fraction (LVEF) ≥ 50%; and severe left atrial (LA) enlargement in the absence of LV dysfunction, leaflet pathology, or LV tethering. The diagnosis of A-FMR (vs. ventricular-FMR [V-FMR]) was confirmed by three independent echocardiographers. Baseline characteristics, procedural outcomes as well as clinical and echocardiographic follow-up are reported. Device success was defined as final MR grade ≤ moderate; MR reduction ≥1 grade; and final transmitral gradient <5 mmHg. RESULTS 306 patients underwent MTEER, including DMR (62%), FMR (19%), and mixed MR (19%). FMR cases included 37 (63.8%) V-FMR and 21 (36.2%) A-FMR. Tricuspid regurgitation (≥ moderate) was higher in A-FMR (80.1%) compared to V-FMR (54%) and DMR (42%). Device success did not significantly differ between A-FMR and V-FMR (57% vs. 73%, p = 0.34) or DMR (57% vs. 64%, p = 1.0). The A-FMR cohort was less likely to achieve ≥3 grades of MR reduction compared to V-FMR (19% vs. 54%, p = 0.01) and DMR (19% vs. 49.7%, p = 0.01). Patients with V-FMR and DMR demonstrated significant reductions in mean left atrial pressure (LAP) and peak LA V-wave, though A-FMR did not (LAP -0.24 ± 4.9, p = 0.83; peak V-wave -1.76 ± 9.1, p = 0.39). In follow-up, echocardiographic and clinical outcomes were similar. CONCLUSIONS In patients undergoing MTEER, A-FMR represents one-third of FMR cases. A-FMR demonstrates similar procedural success but blunted acute hemodynamic responses compared with DMR and V-FMR following MTEER. Dedicated studies specifically considering A-FMR are needed to discern the optimal therapeutic approaches.

Abstract
Objectives To evaluate invasive hemodynamics in assessing MC therapy success as well as evaluate its effectiveness as a predictor of functional outcomes. Background Mitral regurgitation grade is a poor predictor of functional outcomes after a MitraClip. There is a paucity of data on invasive hemodynamics as a predictor of outcomes. Methods Sixty-nine patients underwent MC between 2015 and 2018 at the University of Minnesota Medical Center and were retrospectively analyzed. Invasive hemodynamics were performed before and after device deployment with transesophageal echocardiographic guidance. Statistical analysis was performed using STATA version 16. Student's t test was used for continuous variables and Pearson's chi-squared test for categorical variables. Mann-Whitney test was performed for continuous variables where data were not normally distributed. Logistic and linear regression were used to investigate relationships between variables and outcomes. Results A total of 69 patients were included in the study. The mean age was 83 (75-87) years and 38 (55%) were male. Eighty-one percentage had >/= NYHA III symptoms. Eighty-seven percentage had severe MR. Pulmonary capillary wedge pressure was 20 (15-24). Overall, there was significant improvement in left atrial pressure including mean left atrial pressure index, MR, and NYHA class after MC (<.001). There was no significant association between invasive hemodynamics (including left atrial mean pressure index or its reduction rate) and functional outcomes (p = NS). MR grade was also not predictive of functional outcomes. Conclusion Left atrial pressure may not be a significant predictor of functional outcomes, and, in isolation, may not be an improvement over MR grade.

Abstract
BACKGROUND Transcatheter mitral valve replacement (TMVR) has emerged as a feasible alternative to redo surgical mitral valve replacement (SMVR) in patients with degenerated mitral prostheses, with limited comparative data. METHODS We compared mid-term outcomes in patients with degenerated mitral valve prostheses treated with TMVR or redo SMVR. The primary endpoint was survival at 5 years of follow-up. RESULTS From 2014 to 2020, 215 patients presented with degenerated mitral valve prostheses. Of whom 86 (40%) were treated with TMVR (75[87%] valve-in-valve and 11[13%] valve-in-ring), while 129 patients (60%) underwent SMVR. The TMVR cohort was older (p < 0.0001), more symptomatic (p = 0.0003) and had more chronic lung disease (p = 0.02), worse renal function (p = 0.02) and higher right ventricular systolic pressures (p < 0.0001). Thirty-day mortality was lower with TMVR versus SMVR (2.4% vs. 10.2%, OR4.69 [95% CI 1.25-30.5], p = 0.04) with probability of mortality at 1, 2, and 5 years being 14.7% versus 17.5%, 24.5% versus 20.7%, and 49.9% versus 34.0%, respectively. Mode of prosthesis degeneration, baseline hemodynamics, and valve selection did not appreciably impact outcomes. CONCLUSIONS TMVR for degenerated mitral prostheses is associated with better early survival compared to SMVR despite a greater burden of comorbidities. In contrast, 5 year survival rates appear more favorable with SMVR, which may reflect the lower baseline risk of this population. Clinical, hemodynamic, and echocardiographic follow-up support the mid-term durability of TMVR for degenerated mitral prostheses. Further dedicated studies, however, are required to optimize outcomes in this challenging patient cohort and to navigate the choice of approach for each individual patient.

Abstract
BACKGROUND Investigational transcatheter edge-to-edge repair (TEER) for severe tricuspid regurgitation (TR) has shown promise as an alternative to surgery, but factors influencing outcomes, optimal patient selection, and procedural timing remain incompletely defined. Given the limitations of determining TR severity by conventional echocardiography, our objectives were to determine whether invasive right atrial (RA) pressures performed during the procedure are related to patient outcomes. METHODS This study was a retrospective review of patients who underwent off-label tricuspid TEER using MitraClip (Abbott Vascular, Menlo Park, CA) for significant TR at a single institution. Intraprocedural mean RA pressure, RA peak V-wave, RA pressure nadir, and systolic increase in RA pressure (XV height) were recorded. RESULTS Thirty-eight patients underwent tricuspid TEER; 33 underwent concomitant mitral TEER for mitral regurgitation. The study cohort was 39% female with a mean age of 78.6±14.3 years. Median follow-up was 339 days (interquartile range, 100-601). Any reduction in mean RA pressure, RA peak V-wave, RA nadir, and XV height occurred in 74%, 82%, 45%, and 87% of patients, respectively. At 1 year, event-free survival was 47%. Postprocedure XV height correlated with TR severity as determined by echocardiography (P<0.0001). The highest quartile of postprocedure XV height (>8 mm Hg) had worse event-free survival compared with those who had concluding XV height ≤8 mm Hg (P=0.02). Attainment of a concluding XV height less than or equal to median value was associated with a lower creatinine the next day (1.27±0.47 versus 1.64±0.47 mg/dL, P=0.04). CONCLUSIONS Intraprocedural XV height correlates with TR severity after tricuspid TEER, and lower concluding pressures are associated with improved outcomes. Analysis of RA pressures may serve as a complementary tool for the evaluation of disease severity and procedural guidance.

Change in Invasively Measured Mean Pulmonary Artery Pressure After Transcatheter Mitral Valve Repair Is Associated With Heart Failure Readmission. Cardiol Res 2021; 12:302-308. [PMID: 34691328 PMCID: PMC8510655 DOI: 10.14740/cr1284] [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: 05/27/2021] [Accepted: 07/02/2021] [Indexed: 11/30/2022] Open
Abstract
Background Pre-existing pulmonary hypertension is associated with poor outcomes after transcatheter mitral valve repair (TMVr) for mitral regurgitation (MR). However, the impact of an immediate change in mean pulmonary artery pressure (ΔmPAP) following TMVr on outcomes is unknown. Methods Patients who underwent TMVr from December 2015 to February 18, 2020 at our institution for symptomatic 3-4+ MR and who had invasive hemodynamics measured immediately pre- and post-TMVR were included. Multivariate Cox regression analysis was performed to examine the association of ΔmPAP (post-TMVr - pre-TMVr mPAP) with the primary endpoint of heart failure (HF) readmission at 1 year. Secondary endpoints included all-cause mortality and the composite endpoint of HF readmission or all-cause mortality at 1 year. Results Among 55 patients, 55% were men, mean age was 72 ± 14.2 years, and mean ΔmPAP was -1.4 ± 8.2 mm Hg. Overall, HF readmission occurred in 14 (25%), death in 10 (18%), and the composite endpoint in 20 (36%) patients. In multivariable analyses, higher ΔmPAP was significantly associated with HF readmission (hazard ratio (HR) = 1.10, 95% confidence interval (CI): 1.00 - 1.21; P = 0.04). ΔmPAP was not associated with death (HR = 1.04, 95% CI: 0.96 - 1.14; P = 0.33), though there was a numerical but statistically non-significant trend towards the composite endpoint (HR = 1.06, 95% CI: 1.00 - 1.13; P = 0.06) driven by HF readmission. Conclusion Higher ΔmPAP immediately following TMVr was associated with increased HF readmission at 1 year. Larger prospective studies are needed to validate these data and further explore the utility of ΔmPAP as a novel hemodynamic parameter to predict post-TMVR outcomes.

Abstract
This series reports the safety and feasibility of MitraClip (Abbott Vascular) in 7 high surgical risk Indian patients with symptomatic mitral regurgitation (MR). The clip was deployed successfully in all patients, and more than one clip was required in 5. All had reduction in MR to ≤2+. Mean mitral valve gradient was 3.0 ± 0.8 mmHg. At 12 months follow up, all were alive, and the MR grade was 1+ in 6 patients and 2+ in one. Mean MV gradient was 3.4 ± 1.0 mmHg. The modified Kansas City Quality of life (KCQ) analysis revealed significant improvement in their quality of life (p < 0.0001).

The effects of interventional mitral valve repair using the MitraClip System on the results of pulmonary function testing, pulmonary pressure and diffusing capacity of the lung. BMC Cardiovasc Disord 2021; 21:235. [PMID: 33975538 PMCID: PMC8112049 DOI: 10.1186/s12872-021-02042-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Accepted: 04/27/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The study analyzes changes in lung function, pulmonary pressure and diffusing capacity of the lung in patients with mitral valve regurgitation (MR) treated by MitraClip implantation. METHODS A total of 43 patients (19 women and 24 men with an average age of 78.0 ± 6.6 years) who were able to perform pulmonary function testing including diffusing capacity of the lung for carbon monoxide (DLCO), vital capacity (VC), total lung capacity (TLC), residual volume (RV) and forced expiratory volume in 1 s (FEV1) before and 6 weeks after MitraClip implantation participated in this study. Furthermore, clinical and echocardiographic parameters including systolic pulmonary artery pressure (sPAP), left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) measurements were recorded in all patients. RESULTS The procedure was performed successfully in all 43 patients leading to a reduction of MR in 97.7% of cases. One patient died on day 4 after the intervention most likely due to pulmonary artery embolism. Six weeks after the implantation 79.1% of patients showed a MR of at most mild to moderate. Furthermore, we could demonstrate a significant reduction of systolic pulmonary artery pressure during follow-up (from 48.8 ± 11.4 mmHg to 42.9 ± 9.0 mmHg (t(41) = - 2.6, p = 0.01). However, no changes in LVEF were detected. Comparing pre and post implant lung function tests, no significant alterations were seen for VC, TLC, DLCO and FEV1. Though, in a subgroup of patients with moderate to severe preexisting deterioration of DLCO at the baseline (max. 50%) the MitraClip procedure resulted in a significant improvement in DLCO (37.8% ± 9.0 to 41.6% ± 10.0, p < 0.001). CONCLUSIONS Treatment of MR with the MitraClip system successfully reduces MR severity in the vast majority of patients. Consecutively, a reduction in pulmonary pressure could be observed, however no changes in LVEF were obvious. Lung function tests remained unaltered during follow-up. However, in a subgroup of patients with severe preexisting deterioration of DLCO the MitraClip procedure resulted in a significant improvement in DLCO.

Abstract
BACKGROUND Change in left atrial pressure (LAP) has been shown to be associated with symptom improvement post-MitraClip; however, the association between acute procedural changes in transmitral diastolic mean gradient (MG) compared to LAP and symptom improvement is not well established. METHODS 164 consecutive patients undergoing MitraClip at Mayo Clinic between June 2014 and May 2018 were included. Preclip and postclip MG and LAP were recorded. Baseline demographics, clinical, and echocardiographic outcomes, including 30-day New York Heart Association (NYHA) functional status were obtained from patient charts. RESULTS Median age was 81.5 years (IQR: 76.3, 87), 34% were female and 94.5% had NYHA class III and IV functional status at baseline. At baseline, median MG was 4 mmHg (IQR: 3, 5) and LAP was 19 mmHg (IQR: 16, 23.5). Following MitraClip deployment, the median MG was 4 mmHg (IQR: 3, 6) and the median LAP was 17 mmHg (IQR: 14, 21), 69.5% of patients had less than moderate MR. There was no statistically significant association between change in MG and NYHA functional class at 30 days (OR = 0.95, 95% CI: 0.76-1.20). However, a reduction in LAP following MitraClip deployment was significantly associated with improvement in NYHA functional status at 30 days following adjustments for age and sex (aOR 3.36, 95% CI: 1.34-8.65). There was no significant correlation between change in mean LAP and change in MG (p = .98). CONCLUSION Unlike change in left atrial pressure, change in MG post-MitraClip was not associated with patient reported outcomes at 30 days and did not correlate with change in left atrial pressure. Long-term follow up is needed to evaluate the impact of LA pressure on symptoms.

Abstract
Transcatheter edge-to-edge mitral valve repair has revolutionized the treatment of primary and secondary mitral regurgitation. The landmark EVEREST (Endovascular Valve Edge-to-Edge Repair Study) and COAPT (Clinical Outcomes Assessment of the MitraClip Percutaneous Therapy for High Surgical Risk Patients) trials included only clinically stable patients with favorable mitral valve anatomy for edge-to-edge repair. However, since its initial commercial approval in the United States, growing operator experience, device iterations, and improvements in intraprocedural imaging have led to an expansion in the use of transcatheter edge-to-edge repair to more complex mitral valve pathologies and clinical scenarios, many of which were previously considered contraindications for the procedure. Because patients with prohibitive surgical risk are often older and present with complex mitral valve disease, knowledge of the potential effectiveness, versatility, and technical approach to a broad range of anatomy is clinically relevant. In this review the authors examine the current experience with mitral valve transcatheter edge-to-edge repair in various pathologies and scenarios that go well beyond the EVEREST II trial inclusion criteria.

Abstract
Transcatheter mitral valve repair with MitraClip is a novel, intricate therapy for mitral regurgitation that improves survival and quality of life. Similar to other medical procedures, there is a relationship between procedural experience and clinical outcomes. MitraClip results and the efficiency and safety of the procedure all improved with increasing experience at both the institutional and operator level in two large studies from the Society of Thoracic Surgeons and American College of Cardiology Transcatheter Valve Therapy Registry. Patient selection was also found to have a significant role in procedure success. The old adage of “See one, do one, teach one” does not necessarily apply to complex interventions, such as MitraClip, given that the learning curve does not appear to plateau even as operators approach a 150-case experience.

Association of transcatheter direct mitral annuloplasty with acute anatomic, haemodynamic, and clinical outcomes in severe mitral valve regurgitation. ESC Heart Fail 2020; 7:3336-3344. [PMID: 32915515 PMCID: PMC7755018 DOI: 10.1002/ehf2.12957] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 07/08/2020] [Accepted: 08/03/2020] [Indexed: 11/06/2022] Open
Abstract
AIMS Several approaches for transcatheter mitral valve repair for functional mitral valve regurgitation are established. Interventional direct annuloplasty is a novel trans-venous, trans-septal approach. While feasibility was proven recently, knowledge on its influence on cardiac dimensions, pressures, biomarkers, and clinical outcomes is sparse. METHODS AND RESULTS Patients consecutively treated with direct annuloplasty-only procedures between December 2015 and April 2018 were included in this monocentric analysis. Echocardiographic measurements, biomarker levels, clinical status [New York Heart Association (NYHA) class and 6 min walk test] were assessed at baseline, at discharge, and at a 30 day follow-up. Overall, 18 patients (in mean 77.0 ± 7.4 years, 44.4% women) with initially all high-grade mitral valve regurgitation (MR) were included in this study. Procedural success rate was high (94.4%) without severe complications. Direct annuloplasty resulted in MR-reduction (post-procedural-MR mild or no/trace: 72.2%) and the proportion of patients with severe dyspnoea (NYHA III/IV) was reduced (88.9% vs. 50%, P = 0.008). Clinical results were associated with a relevant diminution of left atrial volumes (-16.5%, P < 0.001) and cardiac pressures [left atrial pressure (-32.3%, P = 0.019) and systolic pulmonary arterial pressure (PAP, -15.8%, P = 0.025)]. Patients with lower baseline levels of PAP (P = 0.022) as well as elevated highly sensitive troponin (P = 0.034) were more likely to archive clinical benefit (improvement in NYHA class ≥1 grade) after 1 month, which could not be correlated with the grade of MR-reduction. CONCLUSIONS Transcatheter mitral valve repair by direct annuloplasty results in a relevant reduction of intracardiac pressures, left atrial volumes, dyspnoea, and MR. Lower PAP and higher troponin values at baseline could be associated to dyspnoea reduction.

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
Background and objectives MitraClip implantation is an established therapy for secondary mitral regurgitation (MR) in high-risk patients and has shown to improve several important outcome parameters such as functional capacity. Patient selection is both challenging and crucial for achieving therapeutic success. This study investigated baseline predictors of functional improvement as it was quantified by the six-minute walk distance (6MWD) after transcatheter mitral valve repair. Methods and results We retrospectively analyzed 79 patients with secondary MR treated with MitraClip implantation at an academic tertiary care center. Before and four weeks after the procedure, all patients underwent comprehensive clinical assessment, six-minute walk tests and echocardiography. 6MWD significantly improved after MitraClip therapy (295 m vs. 265 m, p < 0.001). A linear regression model including seven clinical baseline variables significantly predicted the change in 6MWD (p = 0.002, R2 = 0.387). Female gender, diabetes mellitus and arterial hypertension were found to be significant negative predictors of 6MWD improvement. At baseline, female patients had significant higher left ventricular ejection fraction (49% vs. 42%, p = 0.019) and lower 6MWD (240 m vs. 288 m, p = 0.034) than male patients. Conclusion MitraClip implantation in secondary MR significantly improves functional capacity in high-risk patients even in the short term of four weeks after the procedure. Female gender, diabetes mellitus and arterial hypertension are baseline predictors of a less favourable functional outcome. While further validation in a larger cohort is recommended, these parameters may improve patient selection for MitraClip therapy.

Abstract
OBJECTIVE Determine the rates, reasons, predictors, and costs of 30-day readmissions following transcatheter mitral valve repair (TMVR) versus surgical mitral valve repair (SMVR) in the United States. BACKGROUND Data on 30-day readmissions after TMVR are limited. METHODS High-risk patients with mitral regurgitation (MR) undergoing TMVR or SMVR were identified from the 2014-2015 Nationwide Readmissions Databases. Multivariable stepwise regression models were used to identify independent predictors of 30-day readmission. Risk of 30-day readmission was compared between the two groups using univariate and propensity score adjusted regression models. RESULTS Among 8,912 patients undergoing mitral valve repair during 2014-2015 (national estimate 17,809), we identified 7,510 (84.7%) that underwent SMVR and 1,402 (15.3%) that underwent TMVR. Thirty-day readmission rates after SMVR and TMVR were 10.7% and 11.7%, respectively (unadjusted OR 1.11, 95% CI 0.89-1.39, p = .35). After propensity score adjustment, TMVR was associated with a lower risk of 30-day readmissions compared with SMVR (adjusted OR 0.70, 95% CI 0.51-0.95, p = .02). Heart failure and arrhythmias were the leading cardiac reasons for readmission. Anemia and fluid and electrolyte disorder were independent predictors of 30-day readmission after TMVR. Demographics, comorbidities, and length of stay were independent predictors of 30-day readmission after SMVR. CONCLUSIONS One in 10 patients are readmitted within 30 days following TMVR or SMVR. Approximately half of the readmissions are for cardiac reasons. The predictors of 30-day readmission are different among patients undergoing TMVR and SMVR, but can be easily screened for to identify patients at highest risk for readmission.

Abstract
Significant mitral regurgitation (MR) may be present in up to half of patients with heart failure (HF) and it is associated with adverse cardiac remodeling and myocardial stretch. These are potential triggers for ventricular arrhythmias (VA) in patients with HF, and therefore MR may enhance electrical ventricular vulnerability. Our aim was to evaluate VA burden before and after percutaneous mitral valve repair (PMVR) in patients with implantable cardiac devices. We conducted a prospective registry of all consecutive patients (n = 34, age 69.0 ± 12.2 years, 77% male) with significant functional mitral regurgitation (FMR) who underwent MitraClip implantation in 2 centers between June 2014 and July 2018. VA burden was defined as the total number of events during device follow-up before and after PMVR. Among patients presenting VA during follow-up before or after PMVR, device success at hospital discharge was related to a significant reduction in the incidence of Nonsustained ventricular tachycardia (VT, p = 0.002) and any sustained VT or rapid VT/ventricular fibrillation (p = 0.034). Regarding implantable cardiac defibrillator (ICD) therapies, successful PMVR was related to a reduction in incidence of either antitachycardia pacing or appropriate shocks (p = 0.045) and in the occurrence of any defibrillation shocks (p = 0.045). Overall, effective repair lead to a significant reduction in the VA burden, with a significant decrease in the occurrence of any VA (p = 0.004) and any ICD therapies (p = 0.045). In conclusion, device success after PMVR was related to a reduction in overall arrhythmic burden and ICD therapies in our cohort.

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
Aims The aim of this study is to evaluate changes in cardiopulmonary exercise test (CPET) after percutaneous mitral valve repair (PMVR) with MitraClip in patients with heart failure with reduced ejection fraction who are potentially candidates for heart transplantation or destination left ventricular assist device. Methods and results Prospective registry of all consecutive patients with heart failure with reduced ejection fraction and functional mitral regurgitation (MR) underwent elective PMVR between October 2015 and March 2018 in our institution. Patients with preserved or mid‐range left ventricular ejection fraction (>40%), advanced age (>75 years old), or severe co‐morbidities (end‐stage organ damage) were not included. Treadmill exercise testing with respiratory gas exchange analysis was carried out in 11 patients (male, 72.7%; median age, 67 years old) within the month prior to the procedure and at 6 month follow‐up. PMVR was successfully performed in all patients. At 6 month follow‐up, PMVR was associated with an improvement in New York Heart Association functional class (P = 0.021) and a reduction in MR severity (P = 0.013) and N‐terminal pro‐brain natriuretic peptide levels (2805 [1878–5022] vs. 1485 [654–3032] pg/mL; P = 0.012). All patients completed pre‐procedural and post‐procedural CPET, and all the studies showed a respiratory exchange ratio ≥1 and were consistent with sufficient exercise effort. Compared with pre‐procedural CPET, patients showed a significant increase in exercise time (295 [110–335] vs. 405 [261–540] s; P = 0.047), VO2 (9.8 [9.1–13.4] vs. 13.5 [12.1–16.8] mL/kg/min; P = 0.033), ventilatory anaerobic threshold (510 [430–950] vs. 850 [670–1070] mL/kg/min; P = 0.033), peak O2 pulse (7.2 [4.3–8.6] vs. 8.3 [6.2–11.8] mL/beat; P = 0.033), and workload (5 [3–6] vs. 6 [5–8] metabolic equivalents; P = 0.049). Conclusions Percutaneous mitral valve repair with MitraClip was associated with an enhancement in cardiopulmonary performance in patients with systolic heart failure and secondary MR.

Abstract
OBJECTIVES To assess impact of left ventricular (LV) chamber remodeling on MitraClip (MClp) response. BACKGROUND MitraClip is the sole percutaneous therapy approved for mitral regurgitation (MR) but response varies. LV dilation affects mitral coaptation; determinants of MClp response are uncertain. METHODS LV and mitral geometry were quantified on pre- and post-procedure two-dimensional (2D) transthoracic echocardiography (TTE) and intra-procedural three-dimensional (3D) transesophageal echocardiography (TEE). Optimal MClp response was defined as ≤mild MR at early (1-6 month) follow-up. RESULTS Sixty-seven degenerative MR patients underwent MClp: Whereas MR decreased ≥1 grade in 94%, 39% of patients had optimal response (≤mild MR). Responders had smaller pre-procedural LV end-diastolic volume (94 ± 24 vs. 109 ± 25 mL/m2 , p = 0.02), paralleling smaller annular diameter (3.1 ± 0.4 vs. 3.5 ± 0.5 cm, p = 0.002), and inter-papillary distance (2.2 ± 0.7 vs. 2.5 ± 0.6 cm, p = 0.04). 3D TEE-derived annular area correlated with 2D TTE (r = 0.59, p < 0.001) and was smaller among optimal responders (12.8 ± 2.1 cm2 vs. 16.8 ± 4.4 cm2 , p = 0.001). Both 2D and 3D mitral annular size yielded good diagnostic performance for optimal MClp response (AUC 0.73-0.84, p < 0.01). In multivariate analysis, sub-optimal MClp response was associated with LV end-diastolic diameter (OR 3.10 per-cm [1.26-7.62], p = 0.01) independent of LA size (1.10 per-cm2 [1.02-1.19], p = 0.01); substitution of mitral annular diameter for LV size yielded an independent association with MClp response (4.06 per-cm2 [1.03-15.96], p = 0.045). CONCLUSIONS Among degenerative MR patients undergoing MClp, LV and mitral annular dilation augment risk for residual or recurrent MR, supporting the concept that MClp therapeutic response is linked to sub-valvular remodeling.

Abstract
BACKGROUND MitraClip is an effective transcatheter therapy for mitral regurgitation (MR). However, MitraClip is challenging in commissural MR and the optimal therapeutic approach is unclear. METHODS We describe a case series of six consecutive patients with severe commissural primary mitral regurgitation who underwent MitraClip insertion followed by an Amplatzer Vascular Plug (AVP) II occluder between the commissure and the MitraClip. RESULTS The procedure was successful in all patients. MR was reduced from severe to mild/trivial in 50% and moderate in 50% of cases. On 30-day follow-up, NYHA class had improved from III (6 patients) to I (2 patients), II (2 patients), and III (2 patients). The mean transmitral gradient was 2.5 ± 1.8 mmHg at baseline and 4.8 ± 2.6 mmHg following the procedure. One patient developed hemolysis immediately post procedure. The other five patients remained well during a median follow-up of 20 months (range 5-50 months) with no reported device dislodgement. CONCLUSIONS Elective treatment of severe commissural MR with a laterally or medially placed MitraClip coupled with an AVP II occluder between the clip and the commissure is feasible and safe. This approach may provide a useful management alternative in selected patients.

Abstract
OBJECTIVES To measure the intraprocedural change in left atrial pressure (LAP) with saline administration during transcatheter mitral valve repair (TMVR). BACKGROUND TMVR with MitraClip offers an alternative to surgery in select patients. During this procedure, large volumes of fluid are routinely administered with anesthesia and to facilitate transcatheter valve repair. LAP, a measure used to guide repair, may thereby change as a result of volume expansion, suggesting a need for continuous intracardiac pressure monitoring. METHODS Consecutive patients with severe mitral regurgitation underwent TMVR with MitraClip and continuous LAP monitoring through a dedicated sampling catheter. Specific LAP values were acquired immediately after transseptal access; before first clip deployment; and after deployment of the last clip. RESULTS 151 patients (age 80 ± 8 years, 64% male) underwent TMVR with MitraClip and continuous LAP monitoring. Mean LAP and v-wave pressure increased significantly from baseline to pre-MitraClip deployment (P < 0.0001) and decreased significantly from deployment to procedure end (P < 0.0001). Linear regression of v-wave pressure change (from procedure start to clip deployment) relative to volume administration yielded a significantly nonzero slope (0.28 mmHg/min, P < 0.0001, r = 0.30). CONCLUSION Fluid administration during TMVR leads to time-dependent increases in LAP. Such intraprocedural change underscores the need for targeted, if not continuous, LAP measurement during TMVR to optimize MitraClip placement and mitral regurgitation reduction.

Effect of Atrial Fibrillation and Mitral Valve Gradients on Response to Percutaneous Mitral Valve Repair With the MitraClip System. Am J Cardiol 2018; 122:1371-1378. [PMID: 30103906 DOI: 10.1016/j.amjcard.2018.06.050] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Revised: 06/26/2018] [Accepted: 06/28/2018] [Indexed: 11/23/2022]
Abstract
Both pre-existing atrial fibrillation (AF) and mitral valve pressure gradients (MVPG) created by MitraClip implantation have demonstrated predictive power for unfavorable outcomes. Therefore, we aimed to assess the impact of MVPG following MitraClip on outcomes in patients with and without AF. A total of 200 patients who underwent MitraClip implantation in our institution were enrolled. Echocardiography was obtained before and after the procedure. The primary endpoint of the study was all-cause mortality 1-year after MitraClip implantation. Secondary end points were clinical improvements in NYHA functional class and reduction in MR severity after MitraClip implantation. Two hundred patients (74 ± 10 years, left ventricular ejection fraction 41% ± 14%, logistic EuroSCORE I 21 ± 15) were enrolled into the final analysis. One hundred twelve patients (56%) had pre-existing AF. One-year all-cause mortality was 17% without any differences between patients with or without pre-existing AF. Comparing postprocedural MVPG of surviving and deceased patients, deceased patients with pre-existing AF exhibited significantly elevated postprocedural MVPG compared with surviving patients without AF (4.8 ± 2.1 mm Hg vs 3.6 ± 1.8 mm Hg; p = 0.010). ROC analysis and Kaplan-Meier survival curves identified significantly reduced survival in AF patients with postprocedural MVPG above 4.0 mm Hg (p = 0.011). After MitraClip, a MVPG above 4.0 mm Hg in patients with pre-existing AF was a significant outcome predictor in univariate and multivariate analysis. In conclusion, we identified a high-risk cohort characterized by postprocedural MVPG above 4.0 mm Hg and pre-existing AF predicting poor long-term outcome.

Abstract
Background: Large V waves in the pulmonary capillary wedge pressure (PCWP) waveform traditionally indicate severe mitral regurgitation (MR). However, our understanding of MR etiology and hemodynamics has changed in recent decades. Objectives: We aimed to reevaluate the association between large V waves and current MR to determine whether traditional large V wave criteria remain optimal. Method: We reviewed 1,964 right heart catheterizations (RHCs) performed at our institution from 2010 to 2017, and retrospectively selected 126 patients with sinus rhythm who underwent echocardiography within 2 days (0.3 ± 0.5 days) of the RHC. The diagnostic accuracy of 3 traditional criteria for large V waves was assessed, and the optimal cut-off points were determined as those with the maximal Youden indices. Results: Severe MR was observed on echocardiography in 26 (21%) patients, including 15 (58%) with Carpentier classification type II MR and 11 (42%) with type IIIB MR. Large V waves, defined as a difference between the peak V wave and mean PCWP ≥10 mm Hg, had a high specificity of 94% (95% confidence interval: 87–98%), but a low sensitivity of 27% (12–48%) for diagnosing severe MR. The optimal cut-off point for the V wave was 3 mm Hg above the mean PCWP, with a sensitivity of 73% (52–88%) and a specificity of 64% (54–73%). Conclusions: For diagnosing current MR, the cut-off point for a large V wave should be reduced from that previously employed for rheumatic valvular heart disease. This information may be useful in guiding contemporary transcatheter therapies for MR under RHC monitoring.

Continuous invasive hemodynamic monitoring using steerable guide catheter to optimize mitraclip transcatheter mitral valve repair: A multicenter, proof-of-concept study. J Interv Cardiol 2018; 31:907-915.

Abstract
OBJECTIVES We report our multicenter experience on continuous hemodynamic monitoring using exclusively the steerable guide catheter (SGC) during MitraClip repair. BACKGROUND Left atrial pressure (LAP) and V-wave are useful to evaluate MitraClip repair but no simple method of continuous monitoring exists. METHODS From 11/2016 to 8/2017, 74 patients from four centers with symptomatic moderate-severe to severe mitral regurgitation (MR), underwent MitraClip NT repair with continuous hemodynamic monitoring via the SGC. Real-time LAP/V-wave changes were compared with transesophageal echocardiography (TEE). When mitral stenosis was suspected, transmitral gradients were verified by invasive hemodynamics. Clinical and echocardiographic outcomes were determined. RESULTS Mean age was 78 ± 10 years and STS score 9.1 ± 11.0%. Pathology included leaflet prolapse/flail (45%), restriction (35%), and mixed (20%). Number of clips averaged 1.7 ± 0.7 per case. There was a significant reduction in LAP (21 ± 10 to 15 ± 7 mmHg, P < 0.0001) and V-wave(37 ± 19 to 24 ± 10 mmHg, P < 0.0001) post MitraClip, but the decrease was less in patients with atrial fibrillation (P < 0.05). Transmitral gradient significantly increased from 2.0 ± 1.2 to 4.0 ± 1.7 mmHg (P < 0.0001). Paradoxical increases in LAP and V-wave despite MR reduction were observed in three cases requiring MitraClip repositioning or retrieval to avoid stenosis. Follow-up averaged 5.0 ± 2.9 months and was 100% complete. KCCQ improvement was significant and MR reduction to <1+ was 67% and <2+ was 93% at 30 days. CONCLUSIONS Continuous hemodynamic monitoring using the SGC complements TEE to assess and optimize MitraClip repair in real-time. Further validation is necessary but this feature may be part of future MitraClip and other transcatheter mitral repair systems.
