Case ReportsType 1 aortic dissection with right coronary artery occlusion and fistula to right atrium and right ventricle.
A fistula between the aorta and right atrium which communicates with the right ventricle is an extremely rare and rapidly lethal complication of aortic dissection. There are only three previously reported cases of survival after operative repair of aorto-right atrial fistulae in the literature. We describe a patient who experienced acute aortic dissection with fistula formation to the right atrium and to the right ventricle. The patient underwent successful operative repair.

Case ReportsSystemic atrioventricular conduit for extracardiac bypass of hypoplastic systemic atrioventricular valve.
The management of severe congenital mitral stenosis in infants and children is still controversial. We describe our experience with the use of a systemic atrioventricular (SAV) extracardiac conduit to bypass a hypoplastic systemic atrioventricular valve. An SAV extracardiac conduit has been used in six patients (left atrium--left ventricle in five, right atrium--right ventricle in one). ⋯ Postoperative cardiac catheterization performed in five patients showed reduction of the transmitral gradient from a mean of 16 mmHg to a mean of 5 mmHg. Calcification of the bioprosthetic valve occurred in two patients 3 1/2 years and 2 years respectively after the operation; one died from concomitant subaortic stenosis and one underwent conduit replacement. Although its long-term efficacy is limited, the SAV conduit seems the most reliable surgical option for infants and children with hypoplastic systemic atrioventricular valves unsuited to conventional surgery.
