A newborn with aortico-left ventricular tunnel mimicking sinus of valsalva aneurysm.

ABSTRACT

Aortico-left ventricular tunnel (ALVT) is a rare congenital cardiac anomaly and constitutes less than 0.1% of all congenital cardiac defects (1). ALVT is described as an abnormal connection between the ascending aorta and the left ventricle which originates commonly above the right sinus of valsalva. Most patients are diagnosed with an ALVT during early infancy (2). Although transthoracic echocardiography (TTEAQ5) is more effective in diagnosis of ALVT, misdiagnosis rate was 17.1% (3). Sinus of valsalva aneurysm (SVA) is frequently confused with ALVT (3). We report a term female newborn with SVA in echocardiographic examination, but in surgery, she was diagnosed with ALVT.
