Transcatheter Versus Surgical Closure of Acute Ruptured Sinus of Valsalva Aneurysms with Associated Ventricular Septal Defects.

Transcatheter ruptured sinus of valsalva aneurysm (RSOVA) closure is an alternative to surgery. When a restrictive ventricular septal defect (rVSD) coexists, there are doubts about support for an occluder and persistent left ventricular (LV) dilatation. We compared the outcomes of patients from a single centre with rVSD and RSOVA after surgery or transcatheter intervention in the past 8 years in this study. Location of rVSD did not alter the approach. Compliant balloon interrogation before transcatheter closure was occasionally used to assess significance of interventricular shunt or aortic regurgitation. Procedural success and LV dimensions before and after treatment were analyzed. Seventeen patients with a mean age of 36.64 ± 12.58 years were analyzed. 12/13 catheter procedures (92%) were successful, of whom eight patients had an outlet VSD. rVSD was closed with device in one patient with perimembranous rVSD, but unaddressed in others. Four patients underwent balloon interrogation. Surgery included the single patient who failed intervention. Transcatheter group had more acute symptoms and advanced functional class than surgical group, though not significant. At a median follow-up of 4.5 (1-7.5) years, the mean LV dimensions (50.3 ± 10.1 mm and 50.1 ± 3.1 mm, p = 0.46) were not different in the transcatheter and surgical groups. Mean end-diastolic volumes (110.5 ± 42. 1 ml and 98.5 ± 37.5 ml, p = 0.91) were not significantly different either. Transcatheter RSOVA closure success was not altered by rVSD despite their location underneath the aneurysms, including outlet rVSD with defect in aortoventricular junction. Persistent LV dilatation was not observed after catheter intervention even when the VSD was not closed.
