Aorto-ventricular tunnel is a congenital, extracardiac channel which connects the ascending aorta above the sinutubular junction to the cavity of the left, or (less commonly) right ventricle. The exact incidence is unknown, estimates ranging from 0.5% of fetal cardiac malformations to less than 0.1% of congenitally malformed hearts in clinico-pathological series. Approximately 130 cases have be...

متن کاملAorto-Right Ventricular Tunnel in Transposition of the Great Arteries

In all published reports the leaflet involved was either the right coronary leaflet, most frequently, or the left coronary leaflet, in most of the cases opening toward the left ventricle, with only one-eighth of the reported cases communicati...
متن کاملAorto-right ventricular tunnel causing functional tricuspid atresia.
A girl with symmetrical intrauterine growth retardation and a birth weight of 2240 g was delivered at term by primary cesarean section to a 27-year-old primiparous woman. Fetal echocardiography had shown a nearly atretic tricuspid valve. Postnatally, the child stabilized rapidly but showed signs of heart failure with tachypnea and general weakness, as well as cyanosis (transcutaneous oxygen sat...
متن کاملAorto-left ventricular tunnel in a multianeurysmal heart.
A 25-year-old male presented to us with multiple episodes of syncope during the past 6 months. Physical examination was remarkable for bradycardia, an increased pulse pressure, and a systolico-diastolic murmur associated with thrill at the aortic area. ECG (Figure 1) showed complete heart block with a wide QRS escape. Two-dimensional transthoracic echocardiography with color Doppler (Figures 2 ...
