Aneurysms of the sinus of Valsalva

To evaluate the properties of the coexistent cardiac anomalies associated with the aneurysm of sinus of Valsalva (ASV) and examine the long-term surgical results after operation.

From 1980 to 1994, nine patients (median age 22 years) underwent surgical correction of ASV. Aneurysms originated from the right (n = 5), noncoronary (n = 3) and left coronary sinus (n = 1) and entered into right ventricle (n = 5), right atrium (n = 3). In one patient, ASV originated from the left coronary sinus and unruptured. Coexistent cardiac lesions were aortic valve insufficiency (n = 4), ventricular septal defect (n = 5), patent foramen ovale (n = 1), right ventricular outflow tract obstruction (n = 1) and coronary artery anomaly (n = 2). All patients were symptomatic (sudden onset of symptoms in 3, gradual onset in 6).

Ruptured ASVs were repaired by double approach in which both the involved chamber and the aortic root. Concomitant aortic surgery was performed in four patients (2 replacement, 2 valvuloplasty). VSDs were closed by patch in 4 and by direct suture in 1.

The incidence of coexisting coronary artery anomaly was 22.2%. There was no hospital and late mortality. The mean follow-up period was 6.8 years (range 1 to 14 years). There were no reoperation for leaks of VSD, recurrence of aneurysm and aortic regurgitation. Eight patients were found to be in New York Heart Association class I, one patient in class II.

The risk of the recurrent fistula or VSD is prevented by double approach technique, and also this approach reduces the incidence of late aortic insufficiency. Routinely preoperative coronary angiography must be performed for determine of coronary anomaly.
