We describe a 3-month-old girl who presented with massive and restrictive tricuspid regurgitation due to shortened chordae attached to an abnormal papillary muscle. The condition was improved by myotomy, which resulted in papillary muscle-splitting technique. We successfully treated tricuspid valve dysplasia in a young infant using a rare procedure based on a thorough understanding of the heart's morphologic features.

We report 3 cases of papillary fibroelastoma of the tricuspid valve. Two of them manifested with atypical symptoms of chest pressure and chest pain. Robot-assisted resection was performed to remove the mass while preserving the native valve.

Division of Cardiothoracic Surgery, Department of Surgery, Duke University Medical Center, Durham, North Carolina.
Background: Permanent pacemaker (PPM) placement after mitral valve (MV) repair is affected by concomitant procedures, yet existing literature reports conflicting rates. We aimed to characterize the effect of concomitant operation on risk of need for postoperative PPM in patients who underwent MV repair.
Methods: A retrospective review of a prospectively maintained institutional database (1996-2020) was conducted of consecutive patients undergoing MV repair, including concomitant procedures.
A Novel Template and Cylinder Bioprosthetic Atrioventricular Valve: An Ex Vivo Study.
Ann Thorac Surg Short Rep
December 2023
Division of Cardiac Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania.
Purpose: This ex vivo study aimed to develop and evaluate a novel cylinder bioprosthetic valve for mitral and tricuspid valve replacements, addressing concerns related to valve size, anticoagulation, and postoperative morbidity.
Description: Existing bioprosthetic valves lack annulus-papillary muscle continuity. In contrast, our valve, which is crafted from autologous pericardium, maintains annulus-papillary muscle continuity, maximizes the orifice area when open, and closes in response to rising ventricular pressure, thus preserving mitral valve complexity.
Percutaneous Thrombovegectomy as an Alternative to Surgery for Tricuspid Valve Endocarditis.
Ann Thorac Surg Short Rep
December 2024
Department of Surgery, Virginia Tech Carilion School of Medicine, Roanoke, Virginia.
Background: Undergoing an urgent valve surgical procedure to treat patients with tricuspid valve endocarditis carries a high risk of operative morbidity and mortality. Use of a percutaneous vacuum-assisted system to treat tricuspid valve endocarditis is an alternative to surgical procedures.
Methods: This study retrospectively analyzed data from 187 transcatheter vacuum-assisted aspiration procedures performed in 177 patients with tricuspid valve vegetations at 3 different centers between 2017 and April 2022.
