Am J Emerg Med 2021 Apr 26. Epub 2021 Apr 26.

Coronary Intensive Care Unit, Instituto Nacional de Cardiología Ignacio Chávez, México City, Mexico.

Prosthetic valve thrombosis (PVT) is considered an exceptionally rare condition, often associated with pro-thrombotic factors or suboptimal anticoagulant therapy. Guidelines recommend emergent surgery for patients with left heart valve prosthetic thrombosis who present in cardiogenic shock, and systemic thrombolysis is reserved in scenarios where surgery is not immediately available. However, several factors may affect surgical prognosis and are overlooked by current recommendations. Read More

Narrative review of the contemporary surgical treatment of unicuspid aortic valve disease.

Cardiovasc Diagn Ther 2021 Apr;11(2):503-517

Department of Cardiovascular Surgery, University Heart & Vascular Center, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.

Unicuspid aortic valve disease (UAVD) is a frequent and long-lasting challenge for adult congenital heart disease centers. UAVD patients become usually symptomatic in their twenties or thirties and require a surgical treatment plan which should respect their complete lifespan combined with an adequate quality of life. Unfortunately, all current surgical strategies of congenital aortic valve disease bear some important limitations: (I) Aortic valve replacement using bioprosthetic valves is associated with early structural degeneration and leads frequently to re-operations.
