Machine Learning‐Based Prediction of Mortality in Patients With Mitral Regurgitation: Results From Two Nationwide, Prospective Studies

MedComm, Volume 7, Issue 10, October 2026.
Using two nationwide prospective Chinese cohorts totaling nearly 11,000 patients with significant mitral regurgitation, we developed and externally validated a CatBoost‐based machine learning model for all‐cause mortality prediction. The model achieved AUCs of 0.783 internally and 0.703 externally, outperforming the Cox model, MitraScore, and EuroSCORE

Clinical, Functional, and Quality‐of‐Life Outcomes After Contemporary Transcatheter Edge‐to‐Edge Repair for Primary Mitral Regurgitation in the Very Elderly

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Advanced age may influence the benefits derived from transcatheter edge‐to‐edge repair for primary mitral regurgitation (MR). We explored the impact of age on clinical, echocardiographic, functional, and patient‐reported outcomes after ...

Pulmonary Artery Denervation for Persistent Pulmonary Hypertension After Transcatheter Mitral Edge‐to‐Edge Repair: A Pilot Study and First Application in the Post M‐TEER Setting

Pulmonary Circulation, Volume 16, Issue 4, October 2026.
ABSTRACT Pulmonary hypertension (PH) is common in patients undergoing transcatheter mitral edge‐to‐edge repair (M‐TEER) and is an established determinant of adverse outcomes after intervention. Importantly, persistent PH after technically successful M‐TEER remains associated with ongoing symptoms, right ventricular dysfunction and poor prognosis, yet ...

Nine‐Year Follow‐Up After M‐TEER for Secondary Mitral Regurgitation in a Patient With Cardiogenic Shock

Catheterization and Cardiovascular Interventions, Volume 108, Issue 2, Page 483-488, August 1, 2026.
ABSTRACT Background Transcatheter edge‐to‐edge repair (TEER) has become an established therapeutic option for patients with severe secondary mitral regurgitation (SMR). While randomized trials and registry data have reported outcomes up to 5 years, longer follow‐up data remain scarce.

Impella‐Assisted High‐Risk Percutaneous Coronary Intervention in Cardiogenic Shock With Low‐Flow, Low‐Gradient Aortic Stenosis and Multivessel Coronary Artery Disease: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Patients with cardiogenic shock, low‐flow, low‐gradient aortic stenosis, and multivessel coronary artery disease who are ineligible for surgery present a major therapeutic challenge. Percutaneous mechanical circulatory support may facilitate revascularization in this high‐risk population. A 69‐year‐old man presented after a mechanical fall and

A Case of Venous Tissue Dissection During Transcatheter MitraClip Surgery

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 42-45, July 1, 2026.
ABSTRACT The MitraClip system has been widely used to treat mitral regurgitation. The complications associated with MitraClip surgery typically include clip detachment and mitral valve injury. However, cases of venous tissue dissection during surgery are relatively rare.

Mitral Transcatheter Edge‐to‐Edge Repair in Younger Adults

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Younger patients aged ≤65 years who have significant comorbidities deemed unsuitable for surgery, transcatheter edge‐to‐edge repair (TEER) may serve as an alternative, although the long‐term outcomes remain uncertain.
