title: Ruptured sinus of Valsalva aneurysm: transaortic repair may cause sinus of Valsalva distortion and aortic regurgitation.
abstract: OBJECTIVE
  Recurrent or newly developing aortic regurgitation is a critical problem after the repair of ruptured sinus of Valsalva aneurysm.
  
  
  METHODS
  A retrospective review of 56 patients who underwent surgical repair of ruptured sinus of Valsalva aneurysm between June 1990 and August 2006 was performed. Rupture of the right coronary sinus into the right ventricle was the most common anatomic type (39/56, 69.6%). Preoperative aortic regurgitation equal to or greater than grade II (n = 8, 17.9%) was managed by repair (aortic valvuloplasty, n = 5) or replacement (n = 3). Ruptured sinus of Valsalva aneurysm was repaired primarily (n = 7) or by patching (n = 10) through an aortotomy in 17 patients (transaortic group). In the remaining patients (n = 39), ruptured sinus of Valsalva aneurysm was repaired primarily from the chamber into which the corresponding aortic sinus ruptured, and the aneurysmal sac was reinforced with a supporting patch (non-transaortic group).
  
  
  RESULTS
  Median follow-up duration was 46 months (0.4-177 months). There were 2 late deaths. Excluding 3 patients with aortic valve replacement on aneurysm repair, 11 patients (11/53, 21%) had recurrent or new-onset significant aortic regurgitation (> or = II/IV) during the follow-up period. By multivariable analysis, aortic valvuloplasty at initial operation was the only significant risk factor for postoperative aortic regurgitation (P < .001). After adjustment, the non-transaortic approach appeared to be associated with a lower risk of postoperative aortic regurgitation, with marginal significance (hazard ratio 0.28; P = .058). Five-year freedom from significant aortic regurgitation in the transaortic and non-transaortic groups was 68% +/- 12% and 94% +/- 4%, respectively.
  
  
  CONCLUSIONS
  Transaortic repair of ruptured sinus of Valsalva aneurysm may cause postoperative aortic regurgitation by progressive distortion of the aortic sinus geometry.
