Prognostic Implications of Right Ventricular Dysfunction in Severe Degenerative Mitral Regurgitation.

Background: The prevalence and impact of right ventricular dysfunction (RVD) in degenerative mitral regurgitation (DMR) is unknown. We aimed to determine whether RVD assessed by echocardiography in routine clinical practice is independently associated with mortality in patients with DMR.

Methods And Results: We used data from the MIDA-Q (Mitral Regurgitation International DAtabase-Quantitative) registry, which included patients with isolated DMR due to mitral valve prolapse from January 2003 to January 2020 from 5 tertiary centers across North America, Europe, and the Middle East.

Incidence, Predictors, and Outcomes of Unplanned Coronary Angiography After Transcatheter Aortic Valve Replacement.

Background: Assessment of coronary artery disease (CAD) is critical in managing severe aortic stenosis. Unplanned coronary angiography after TAVR, with or without percutaneous coronary intervention, may present significant challenges.

Objectives: The aim of this study was to evaluate the incidence, predictors, and outcomes of unplanned coronary angiography after transcatheter aortic valve replacement (TAVR).

TRIVALVE Score: A Risk Score for Mortality/Hospitalization Prediction in Patients Undergoing Transcatheter Tricuspid Valve Intervention.

Background: Transcatheter tricuspid valve intervention (TTVI) has been increasingly adopted in recent years for the treatment of patients with tricuspid regurgitation (TR). However, no dedicated risk stratification has been established for patients undergoing TTVI.

Objectives: The aim of the present study was to propose a dedicated risk score for patients affected by severe TR undergoing TTVI.

Degenerative Mitral Stenosis by echocardiography: presentation and outcome.

Backgroud: Degenerative-mitral-stenosis (DMS) is due to degenerative mitral-annular (MAC) and valvular calcification. However, DMS impacts on outcome, and therefore potential treatment needs are poorly-known. We aimed at evaluating survival after DMS diagnosis by Doppler-Echocardiography in routine-practice.

Benefit of isolated surgical valve repair or replacement for functional tricuspid regurgitation and long-term outcomes stratified by the TRI-SCORE.

Background And Aims: Severe tricuspid regurgitation is associated with increased mortality rates, but benefit of its correction and ideal timing are not clearly determined. This study aimed to identify patient subsets who might benefit from the surgery.

Methods: In TRIGISTRY, an international cohort study of consecutive patients with severe isolated functional tricuspid regurgitation (33 centres, 10 countries), survival rates up to 10 years were compared between patients who underwent isolated tricuspid valve surgery (repair or replacement) and those conservatively managed, overall and according to TRI-SCORE category (low: ≤3, intermediate: 4-5, and high: ≥6).

Indexing left ventricular end-systolic dimension to body size: Association with mortality in patients with degenerative mitral regurgitation.

Aims: In patients with degenerative mitral regurgitation (DMR), left ventricular (LV) dysfunction is associated with increased risk of heart failure and excess mortality. LV end-systolic diameter (LVESD) is an established trigger for intervention, yet recommended LVESD thresholds apply poorly to patients with small body size. Whether LV normalization to body surface area (BSA) may be used as a trigger for DMR correction is unknown.

Quantification of anatomical aortic valve area by multi-detector computed tomography: A pilot 3D-morphological modeling of the stenotic aortic valve.

Background: Aortic-valve-stenosis (AS) is a frequent degenerative valvular-disease and carries dismal outcome under-medical-treatment. Transvalvular pressure gradient reflects severity of the valve-disease but is highly dependent on flow-conditions and on other valvular/aortic characteristics. Alternatively, aortic-valve-area (AVA) represents a measure of aortic-valve lesion severity conceptually essential and practically widely-recognized but exhibits multiple-limitations.

Clinical Outcomes in Patients With Bicuspid Aortic Valves and Ascending Aorta ≥50 mm Under Surveillance.

Background: Clinical outcomes of bicuspid aortic valve (BAV) patients with ascending aortic diameters ≥50 mm who are under surveillance are poorly defined.

Objectives: The purpose of this study was to assess clinical outcomes in BAV patients with ascending aorta ≥50 mm.

Methods: Multicenter retrospective cohort study of BAV adults with ascending aorta diameters ≥50 mm by transthoracic echocardiography (TTE).

Reappraisal of the Concept and Implications of Pulmonary Hypertension in Degenerative Mitral Regurgitation.

Background: European and U.S. clinical guidelines diverge regarding pulmonary hypertension (PHTN) in degenerative mitral regurgitation (DMR).

Sex-Specific Left Ventricular and Aorta Size Cut-Off Values for Hemodynamically Significant Chronic Aortic Regurgitation - Implications for Treatment in Asian Populations.

Background: There are no sex-specific guidelines for chronic aortic regurgitation (AR). This retrospective study examined sex-specific differences and propose treatment criteria from an Asian AR cohort.

Methods and results: Consecutive 1,305 patients with moderate-severe AR or greater at 3 tertiary centers in Taiwan and Japan (2008-2022) were identified.

Technical and Clinical Outcomes After Transcatheter Edge-to-Edge Repair of Mitral Regurgitation in Male and Female Patients: Is Equality Achieved?

Background: Currently, no clear impact of sex on short- and long-term survival following transcatheter edge-to-edge mitral valve repair (TEER) is evident, although no data are available on postprocedural life expectancy. Our aim was to assess sex-specific differences in outcomes of patients with mitral regurgitation (MR) treated by TEER.

Methods And Results: Short-term and 5-year outcomes in men and women undergoing TEER between 2011 and 2018 who were included in the large, multicenter, real-world MitraSwiss registry were analyzed.

Tricuspid Valve Leaflets-Lead Interaction: Adjunctive Role of Functional Cardiac Computed Tomography for Clinical Decision Making.

The diagnostic approach toward the management of cardiac implantable electronic device-related tricuspid regurgitation is challenging and undefined. Functional cardiac computed tomography angiography provides a complementary role to echocardiography in the evaluation of lead-leaflet interaction which can help the clinical decision-making process, as presented in this case series.

Degenerative mitral regurgitation due to flail leaflet: sex-related differences in presentation, management, and outcomes.

Background And Aims: Presentation, outcome, and management of females with degenerative mitral regurgitation (DMR) are undefined. We analysed sex-specific baseline clinical and echocardiographic characteristics at referral for DMR due to flail leaflets and subsequent management and outcomes.

Methods: In the Mitral Regurgitation International Database (MIDA) international registry, females were compared with males regarding presentation at referral, management, and outcome (survival/heart failure), under medical treatment, post-operatively, and encompassing all follow-up.

Mitral Annular Disjunction in the Context of Mitral Valve Prolapse: Identifying the At-Risk Patient.

Mitral annular disjunction (MAD), a separation between the left atrium/mitral valve annulus and the left ventricular myocardium, is frequently seen in patients with arrhythmic mitral valve prolapse. Although an association exists between MAD and ventricular arrhythmias, little is known regarding the identification of individuals at high risk. Multimodality imaging including echocardiography, computed tomography, cardiac magnetic resonance, and positron emission tomography can play an important role in both the diagnosis and risk stratification of MAD.
