Aortico-left ventricular tunnel in fetuses and infants

Surgical Repair of an Aortico-Left Ventricular Tunnel with Acute Infective Endocarditis

“…Surgical repair is believed to be the proper treatment for ALVT with good late functional results anticipated, according to the type of surgery used in different ways. 2) Several surgical techniques for aorto-left ventricular tunnel repair have been reported in the literature, [1][2][3][7][8][9] the standard technique being closure of the aortic and ventricular openings with two separate patches accompanied by valvular involvement which valvul oplasty or valve replacement may be considered, and transfer of the coronary artery. Type I can be directly sutured.…”

“…Ao-LVT has a congenital etiology [1][2][3], which can be associated with anomalies of the aortic valve and fetal hydrops or not [2]. Depending of the severity of the aortic regurgitation, intrauterine death can occur or the newborn can die within a few hours of birth [2].…”

“…[7] Treatment is basically surgical at any age [1,2,[4][5][6][7] and it is important to avoid distortion of the aortic valve and/or the annulus as well as dilation of the left ventricle, which can in turn cause aortic valve insufficiency and the necessity of reoperation for valve replacement [8]. Regarding the surgical technique, the fistula can be closed by direct suturing through of aortic orifice [6], as demonstrated in this report, or using bovine pericardium patches to close the aortic orifice [5], to occlude the ventricular orifice [4] or to occlude both ventricular and aortic orifices [4].…”

“…The aorta-left ventricle tunnel (Ao-LVT) is considered to be a rare congenital disease [1][2][3], in which there is an abnormal connection between the left ventricle and the aorta, that is, a connection bypassing the aortic valve. Generally, this condition results in severe aortic regurgitation, rapidly evolving to cardiac decompensation and death [l,2].…”
