title: Right coronary system grafts: alone or together with left system grafts--angiographic results.
abstract: OBJECTIVE
  The aim of this study is to compare the long-term graft patency between patients who had sequential or individual right posterior descending artery (RPDA) anastomosis.
  
  
  METHODS
  Two hundred and forty-two patients underwent coronary artery bypass grafting (CABG) between June 1994 and December 2003. They were examined retrospectively with respect to coronary angiograghic data. [Group 1] Individually right system grafts in RPDA position (n=139). [Group 2] RPDA anastomosis sequentially with left system (n=103). Patency rates for posterior descending arteries in each group were separately calculated for each vessel quality category.
  
  
  RESULTS
  The mean interval from operation to angiography was 50.6+/-48.9 months in group 1 vs 57.5+/-39.2 months in group 2 respectively. The overall patency rate was 66.2% (92/139) in group 1 and 78.6% (81/103) in group 2 (p=0.04). When the RPDA has good run-off capacity, the patency rate was 69.1% in group 1 and 85.2% in group 2.
  
  
  CONCLUSIONS
  When the RPDA has good run-off capacity, snake grafts show excellent results and right and left coronary systems could be anastomosed sequentially.
