We report on a man with bioprosthetic mitral valve perforation who presented late after transcatheter aortic valve replacement with a balloon-expandable transcatheter heart valve (THV). The protrusion of the commissural strut of the bioprosthetic mitral valve coupled with the low implanted THV resulted in repetitive trauma leading to rupture of a mitral leaflet. Potential preventive strategies are discussed. This case illustrates the importance of preprocedural imaging screening and cautious THV deployment in patients with a bioprosthetic mitral valve.

Clinical Outcomes After Mitral Valve Replacement With Epic and Mosaic Bioprosthetic Valves.
Ann Thorac Surg Short Rep
June 2024
University Department of Cardiac Surgery, Leipzig Heart Center, Leipzig, Germany.
Background: Comparative studies of outcomes between different biological mitral valve prostheses are scarce. This study compares the late clinical results of valve replacement with the Epic and Mosaic bioprostheses.
Methods: Patients undergoing isolated elective mitral valve replacement (MVR) between 2005 and 2019 were eligible for inclusion.
Reintervention after aortic root replacement with allograft, xenograft, and stented bioprosthetic valves.
Cardiovasc Revasc Med
December 2024
Division of Cardiac Surgery, Department of Cardiothoracic Surgery, University of Pittsburgh, Pittsburgh, PA, United States of America; Heart and Vascular Institute, University of Pittsburgh Medical Center, Pittsburgh, PA, United States of America. Electronic address:
Background: There has been a significant increase in the utilization of non-mechanical valves in the aortic position over time. However, details in reinterventions after aortic root replacement (ARR) with non-mechanical prosthesis were limited in the literature, despite the potential importance of reinterventions in the lifetime management of aortic valve disease.
Methods: This is a single-center retrospective study, identifying all patients who underwent ARR with allograft, xenografts, and stented bioprosthetic valved conduit from 2010 to 2020.
Surgical explantation of an infected Lotus Edge valve: a case report.
Gen Thorac Cardiovasc Surg Cases
December 2024
Department of Cardiovascular Surgery, National Cerebral and Cardiovascular Center, Osaka, 564-8565, Japan.
Background: With the rapid expansion of transcatheter aortic valve replacement (TAVR), TAVR valve explantation is also increasing. Nevertheless, previous reports on Lotus Edge valve explantation are limited to only two reports, none of which include intraoperative videos. Therefore, we report the case of an older adult who underwent a 2-year-old Lotus Edge valve explantation, after developing prosthetic valve endocarditis (PVE) and aortic annular abscess, with a strong indication for a TAVR explantation and surgical aortic valve replacement (AVR).

Aorta (Stamford)
April 2024
Division of Cardiovascular Surgery, Department of Surgery, University of Florida Health, Gainesville, Florida.
A 71-year-old gentleman with prior bioprosthetic aortic valve replacement was admitted with aortic valve dehiscence and an aortic root abscess. He underwent reoperative sternotomy, aortic root, mitral valve, and hemiarch replacement. To augment hemostasis, we implanted the "Martin Mattress"-a pericardial patch sutured to the fibrous ridge within the innominate vein, superior vena cava, right atrium, right ventricular outflow tract, and pulmonary artery-which is preferred to modified Cabrol fistula techniques in infectious root pathology.

ARYA Atheroscler
January 2024
Townsville University Hospital, Townsville, Queensland Australia.
Background: Coronary air embolism (CAE) is a complication that can lead to catastrophic outcomes, including myocardial infarction, stroke, and death. It is reported to occur during cardiac catheterization, within a few hours after cardiac surgery, or as a result of chest trauma. This is a case report of delayed coronary air embolism following cardiac surgery.
