Abstract:
We report a single center experience of surgical treatment of 30 cases of left-sided prosthetic valve thrombosis (PVT). In our series, a diagnosis of PVT was established based on clinical and echocardiographic examinations. Thrombosis was the major etiologic factor in 25 patients (83.3%), while 22 of 25 patients (88%) had a subtherapeutic anticoagulation level. The early hospital mortality rate was 7.1% in patients with New York Heart Association (NYHA) functional classes II - III, and 31.3% in NYHA functional class IV. The median interval from the surgical procedure to follow-up for these patients was 29.2 months. No recurrence or deaths were observed during 3 to 73 months following the surgical procedure.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
