A rare case of prosthetic aortic valve endocarditis complicated with multiple fistula to peri aortic structure
Multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. The case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. A brief review of surgical reconstruction and the existing literature are presented, i...
متن کاملProsthetic Aortic Valve: Current Status.
D RAMATIC ADVANCES HAVE TAKEN place in the surgical treatment of aortic valve disease since 1951 when Huf-nagel' introduced the plastic ball valve for preventing backflow of blood from the descending thoracic aorta. Yet the basic principles of his valve prosthesis9 were those of the currently popular Starr-Edwards valve that is now being implanted in the sub-coronary portion of the excised anat...
متن کاملEffect of prosthetic valve malfunction on the Doppler-catheter gradient relation for bileaflet aortic valve prostheses.
BACKGROUND Considerable discrepancies between Doppler and catheter gradients caused by localized gradients and pressure recovery have been reported for normal bileaflet aortic valve prostheses. METHODS AND RESULTS To examine whether this Doppler-catheter gradient relation is affected by prosthetic valve malfunction, a 19-mm CarboMedics aortic valve was simultaneously studied with continuous-w...
متن کاملSuccessful Use of Two Thrombolytic Drugs in Prosthetic Mitral and Aortic Valve Thrombosis
Introduction: Prosthetic valve thrombosis is a rare and severe complication of valve replacement, most often encountered with a mechanical prosthesis. The significant morbidity and mortality associated with this condition warrant rapid diagnostic evaluation. Although surgery is the first-line therapy in symptomatic obstructive mechanical valve thrombosis, thrombolytic therapy has been used as a...
