A sinus of Valsalva-right atrium fistula without aneurysm formation.
A 61-year-old man was admitted to the hospital because of orthopnea and was diagnosed with heart failure with a continuous heart murmur. A transthoracic echocardiogram revealed turbulent flow from the right coronary sinus of Valsalva to the right atrium throughout the cardiac cycle. Aortography confirmed the presence of a shunt jet from the right coronary sinus of Valsalva to the right atrium. Cardiac catheterization revealed a left-right shunt rate of 47% and a pulmonary to systemic blood flow ratio of 1.81. Transesophageal echocardiography confirmed the existence of the shunt jet and revealed no deformity of the sinus of Valsalva. We report a rare case of sinus of Valsalva-right atrium fistula without typical aneurysmal formation.
