With improved life expectancy and increased use of bioprosthetic heart valves, more elderly and frail patients present with degenerative surgical heart valve disease. The valve-in-valve procedure is an attractive alternative to a conventional open redo procedure. Although it is a novel extension of established transcatheter aortic valve implantation for severe aortic stenosis in a high-risk population, it is gaining momentum worldwide, particularly for aortic and mitral positions. Success depends on the operator being familiar with emerging transcatheter heart valve technology and morphology as well as that of the existing surgical heart valve, patient selection, accurate sizing, an ideal implantation position.

Effects of aortic valve calcification on transcatheter aortic valve replacement for low-flow, low-gradient aortic stenosis.
Cardiovasc Revasc Med
January 2025
Mount Sinai Fuster Heart Hospital, Icahn School of Medicine at Mount Sinai, New York, NY, USA. Electronic address:
Background: Patients with low-flow, low-gradient (LFLG) aortic stenosis (AS) have precarious hemodynamics and are a fragile population for intervention. Quantification of aortic valve calcification (AVC) severity is a critical component of the evaluation for transcatheter aortic valve replacement (TAVR); this study aims to further clarify its utility for risk stratification in LFLG AS.
Methods: This retrospective study evaluated 467 patients with LFLG AS undergoing TAVR at a large quaternary-care hospital from January 2019 to December 2021.
Simplified Outcome Prediction in Patients Undergoing Transcatheter Tricuspid Valve Intervention by Survival Tree-Based Modelling.
JACC Adv
January 2025
Department of General and Interventional Cardiology, Heart and Diabetes Center North Rhine-Westphalia, Ruhr University Bochum, Bad Oeynhausen, Germany. Electronic address:
Background: Patients with severe tricuspid regurgitation (TR) typically present with heterogeneity in the extent of cardiac dysfunction and extra-cardiac comorbidities, which play a decisive role for survival after transcatheter tricuspid valve intervention (TTVI).
Objectives: This aim of this study was to create a survival tree-based model to determine the cardiac and extra-cardiac features associated with 2-year survival after TTVI.
Methods: The study included 918 patients (derivation set, n = 631; validation set, n = 287) undergoing TTVI for severe TR.

Department of Medicine, HeartOtago, Dunedin School of Medicine, University of Otago, Dunedin, New Zealand; Department of Cardiology, Dunedin Hospital, Southern District Health Board, Dunedin, New Zealand.
Aim: There are limited data on the prevalence of calcific aortic valve disease (CAVD) in Māori and known inequities in outcomes after aortic valve intervention. Our study aimed to investigate the prevalence of CAVD in Māori.
Methods: Data from initial clinically indicated echocardiograms performed between 2010 to 2018 in patients aged ≥18 years were linked to nationally collected outcome data.

E-point septal separation (EPSS) and tricuspid annular plane systolic excursion (TAPSE) are M-mode measures of left and right ventricular systolic function, with limited pediatric point-of-care ultrasound (POCUS) research. We conducted a cross-sectional study in a pediatric emergency department, enrolling 12-17-year-olds without cardiopulmonary complaints. Exclusion criteria included abnormal vital signs, fever, altered mental status, or psychiatric illness.

Background: Calcium-mediated autonomic denervation has been shown to suppress postoperative atrial fibrillation (POAF) after coronary artery bypass grafting.
Objectives: This study sought to evaluate whether similar autonomic denervation can prevent POAF after mitral or aortic valve surgeries.
Methods: This research consisted of 2 single-center, randomized, double-blind, sham-controlled trials: CAP-AF2 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Mitral Valve Surgery for Mitral Regurgitation) for mitral valve (MV) surgery and CAP-AF3 (Calcium Autonomic Denervation Prevents Postoperative Atrial Fibrillation in Patients Undergoing Isolated Aortic Valve Surgery) for aortic valve surgery.
