title: A new and simple classification for sinus of Valsalva aneurysms and the corresponding surgical procedure.
abstract: OBJECTIVE
  The classification system of Sakakibara and Konno for sinus of Valsalva aneurysm (SVA) is highly complex and seldom utilized in clinical practice. In this study, we propose a new and simple classification system; we suggest a novel approach that utilizes four distinct types of SVAs.
  
  
  METHODS
  We retrospectively studied 257 cases of SVAs in which surgical repair was performed between October 1996 and December 2009 and divided these cases into four types: I, rupture or protrusion into the right atrium; II, rupture or protrusion into the right atrium or right ventricle near or at the tricuspid annulus; III, rupture or protrusion into the right ventricular outflow tract under pulmonary valve and IV, others. The surgical results of the different approaches in each respective type were compared as follows: cardiopulmonary bypass time, clamp aorta time, mechanical ventilation time, intensive care unit time and postoperative stay time.
  
  
  RESULTS
  In all the patients, there was no early postoperative death; all the patients recovered and were discharged as expected. There were no significant differences in intensive care unit time and postoperative stay time among different approaches in each type (P > 0.05). Two hundred and thirty-eight (92.61%) patients were followed up.
  
  
  CONCLUSIONS
  Surgical repair of SVAs exhibited good long-term results. Our classification of SVA could be potentially helpful for surgical practice. For Type I, the right atrium approach is advised; for Type II, the transaortic approach with a right atrium incision is advised; for Type III, the transaortic approach with pulmonary incision is advised while for Type IV, repair according to the respective situation is advisable.
