Minimally invasive mitral valve replacement redo surgery under ventricular fibrillation in a patient with dextrocardia and situs inversus totalis: a case report.
J Cardiothorac Surg
January 2025
Department of Cardiovascular Surgery, The First Affiliated Hospital, School of Medicine, Zhejiang University, 79#, Qingchun Road, Hangzhou, 310003, China.
Background: Dextrocardia is a rare cardiac malposition where the heart's normal orientation is reversed and is most commonly associated with situs inversus totalis (SIT). Such cases are technically challenging when heart surgery is needed, especially re-do surgery.
Case Presentation: A 72-year-old female patient was referred to our hospital with complaints of chest tightness and reduced activity tolerance.
Risk factors for long-term severe tricuspid regurgitation following mitral valve replacement: a retrospective study.
BMC Cardiovasc Disord
January 2025
Department of Cardiology, Xuzhou Central Hospital, No.199 Jiefang South Road, Quanshan District, Xuzhou, 221009, People's Republic of China.
Background: The aim of this study is to identify factors associated with the development of long-term severe tricuspid regurgitation (TR) following mitral valve replacement (MVR).
Methods: A retrospective analysis was conducted involving 308 patients who underwent single-valve MVR at Xuzhou Central Hospital between April 2017 and December 2022. Preoperative color Doppler ultrasound indicated that all patients had either no or mild to moderate tricuspid regurgitation.
Transcatheter edge to edge compared with surgery in older patients with degenerative mitral valve regurgitation.
J Cardiothorac Surg
January 2025
Cardiology Bichat, AP-HP, Paris, France.
Objectives: Transcatheter edge-to-edge repair (TEER) is an alternative for patients with severe degenerative mitral regurgitation (MR). The objective of this study was to compare the outcomes of surgery and TEER in older patients with degenerative MR patients using real life data.
Methods: Consecutives older patients (≥ 65 years-old), with severe symptomatic, degenerative MR requiring surgery or TEER between 2013 and 2023 were included.
Transcatheter closure of paravalvular leakage through multiple approaches after surgical mechanical valve replacements: A retrospective study.
Medicine (Baltimore)
November 2024
Department of Cardiovascular Surgery, Xijing Hospital, Air Force Medical University, Xi'an, Shaanxi Province, China.
Background: Transcatheter closure of percutaneous paravalvular leak (PVL) is a technically challenging procedure, especially after surgical mechanical valve replacements (SMVR), as the risk of interference with the prosthetic valve discs and the complex interventional techniques required for mitral PVL closure. Our study was designed to review the results with transcatheter closure of PVL after SMVR.
Methods: From January 2018 through December 2023, a total of 64 patients with PVL after SMVR underwent transcatheter closure with the help of preoperative 3-dimensional printing model and simulator for image evaluation.
"A Bridge-over-the Bar": A Novel Strategy to Prevent Paravalvular Regurgitation during Mitral Valve Replacement for Severe Mitral Annular Calcifications.
Ann Thorac Cardiovasc Surg
January 2025
Division of Pediatric and Adult Congenital Cardiac Surgery, Maria Fareri Children's Hospital, Department of Surgery, Westchester Medical Center, New York Medical College, Valhalla, NY, USA.
Mitral annular calcifications have been known to increase complexity during mitral valve replacement (MVR). Standard procedure requires decalcification followed by reconstruction of the mitral annulus prior to placing the prosthesis. While this is the ideal technique, it is not feasible in every patient due to the associated risks.
