Comparison of immediate results and mid-term follow-up of surgical and percutaneous closure of ruptured sinus of Valsalva aneurysm.

BACKGROUND: The past decade has witnessed considerable improvement in implantation techniques for percutaneous closure of ruptured sinus of Valsalva aneurysm. This study was undertaken to compare the immediate results and mid-term follow-up of traditional surgery and percutaneous closure of ruptured sinus of Valsalva aneurysm in China.

METHODS: Between January 1993 and January 2013, a total of 35 patients with ruptured sinus of Valsalva aneurysm were enrolled for attempted closure in our institution. Twenty patients (57.1%) underwent surgical repair and the other 15 patients (42.9%) underwent percutaneous closure.

RESULTS: Nineteen patients (95.0%) in the surgical group had complete closure and 14 patients (93.3%) in the percutaneous closure group were treated successfully (p=0.681). Twelve patients with ruptured sinus of Valsalva aneurysm combined with subarterial ventricular septal defect (VSD) underwent surgical repair concomitantly. Two patients in the percutaneous closure group were treated for ruptured sinus of Valsalva aneurysm and perimembranous VSD using occluders concomitantly. One case of severe hemolysis developed 8h after the procedure in the percutaneous closure group. One death and one case of patch leak occurred in the surgical group during hospitalization. The time of hospital stay in the percutaneous closure group was shorter than that in the surgical group (p=0.004). The total medical cost of isolated ruptured sinus of Valsalva aneurysm in the percutaneous closure group was lower compared with that in the surgical group (p=0.046). During a median follow-up of 15 months (2-240 months), there were no deaths, infective endocarditis, device embolization, or malposition.

CONCLUSIONS: Percutaneous closure is an attractive alternative to surgery in selected patients with ruptured sinus of Valsalva aneurysm for the better clinical advantages and economic benefits.
