Aortic to right atrial fistula secondary to chronic ruptured sinus of Valsalva aneurysm
نویسندگان
چکیده
A sinus of Valsalva aneurysm (SOVA) is an uncommon cardiac anomaly occurring in less than 1% of patients undergoing open cardiac surgical procedures (1). Approximately 65-85% of SOVAs originate from the right sinus of Valsalva, while SOVAs originating from noncoronary (10-30%) and left sinuses (<5%) are less common (2). It may be congenital or acquired in origin and may rupture into any of the cardiac chambers to form an aorto-cardiac fistula. When intra-cardiac rupture occurs, early surgical intervention is indicated as rupture may lead to serious hemodynamic instability, acute heart failure and, if left untreated, has a mean survival period of 1-2 years (3). Although there have been suc

A rare cause of sudden dyspnea and unexpected death in adolescence: fistula from aortic sinus of Valsalva to right atrium.
Aneurysm of the sinus of Valsalva is a rare cardiac abnormality. Unruptured sinus of Valsalva aneurysm is usually asymptomatic, however, a ruptured aneurysm typically leads to an aortocardiac shunt and progressively worsening heart failure. We report a case of a 17-year-old male who suffered an aneurysm of the sinus of Valsalva rupture into the right atrium who manifested sudden dyspnea and acu...

The surgical approach to the repair of a ruptured sinus of Valsalva aneurysm can depend on the cardiac chamber into which rupture occurs. This report details the color flow Doppler images in two patients who developed a right sinus of Valsalva aneurysm to right atrial fistula owing to bacterial endocarditis. In both cases, the color flow Doppler image was superior to contrast aortography in ide...

A N EXPERIMENTAL method for the surgical repair of ruptured sinus of Valsalva aneurysm has previously been described.' In these experiments, acute cardio-aortic fistulas were produced in dogs and subsequently closed by means of a plastic prosthesis introduced through the aorta during a brief period of occlusion of inflow. We have recently had the opportunity to perform this operation in a patie...

متن کاملRuptured congenital sinus of valsalva aneurysms.
BACKGROUND AND AIM OF THE STUDY Rupture of the sinus of Valsalva is rare, and there is a higher incidence of such rupture in Oriental countries than elsewhere. The objective of this study is to present the pathologic features and the clinical outcome after surgery in such patients. METHODS Between 1980 and 2001, a total of 17 patients (15 males and 2 females) with ruptured aneurysm of sinus o...
