Aortico-Right Ventricular Tunnel

Aorto–Right Ventricular Tunnel Causing Functional Tricuspid Atresia

“…ARVT is a rare entity thought to represent abnormal formation of the arterial valvar sinuses and leaflets during embryonic development of the outflow tracts, 1 with only 16 patients reported in the English-language literature to date (Table). [2][3][4] We demonstrate a neonate with ARVT in whom both preoperative echocardiography and angiogra- …”

Successful repair of aortico-left ventricular tunnel associated with severe aortic stenosis in a newborn

“…Our patient had associated severe valvar aortic stenosis and a patent ductus arteriosus, both of which have been reported to occur in conjunction with aortico-left ventricular tunnel [ 1,9,111 . Aortography in this patient demonstrated the pathognomonic finding, a round density just anterior and superior to the origin of the right coronary artery, and filling of the left ventricle without filling of other cardiac chambers [3,6], The diagnosis can be made using two-dimensional and Doppler echocardiography [4,12] .…”

Aorta-right atrial tunnel—a novel therapeutic option

“…The differentiation from coronary-cameral fistula is often difficult [2]. Anatomically aortico-cameral fistula is characterized by its origin above the supra-aortic ridge, with separation of the tunnel orifice from the adjacent sinus of valsalva by a fibrous ridge [6,7]. Rosenberg and colleagues described the characteristic pattern on angiogram of a large tortuous tunnel arisingsuperior to the left Sinus of Valsalva (SOV), passing posterior to the aortic root and opening into the right atriasuperior vena-caval junction.…”
