PG  - 3017-21
AB  - BACKGROUND: Off-pump coronary artery bypass surgery (OPCAB) has been widely 
      applied in recent years as a less invasive method of myocardial 
      revascularization. This study evaluated the sequential bilateral internal mammary 
      artery grafting combined with selective arterialization of the coronary venous 
      system during OPCAB. METHODS: From April 2004 to August 2010, patients with 
      diffuse right coronary lesions were studied retrospectively and divided into two 
      groups. Group 1 included seventeen patients who underwent this surgery while 
      group 2 included twenty-one patients without right coronary artery surgical 
      therapy. All patients presented with symptoms of angina. Blood flow of bridged 
      vessels was measured. The perioperative ventricular parameters including left 
      ventricular ejection fraction and end diastolic diameter were compared. During 
      follow-up, myocardial nuclide imaging and coronary angiography were carried out. 
      RESULTS: Off-pump coronary artery bypass was performed with an average of 3.6 
      grafts per patient. Hospital mortality was zero. At the time of follow-up, the 
      patients in group 1 recovered better than in group 2 (P < 0.05). In both groups, 
      the mean New York Heart Association (NYHA) class and ejection fraction increased 
      significantly (P < 0.001) and the mean left ventricular end-diastolic diameter 
      decreased significantly (P < 0.05). Myocardial blood supply of inferior wall in 
      group 1 was obviously improved by myocardial nuclide imaging. Coronary 
      angiography for eight patients in group 1 verified that there was blood flow to 
      myocardium in the arterialized vein. CONCLUSIONS: Sequential bilateral internal 
      mammary artery grafting combined with selective arterialization of the coronary 
      venous system can be performed during OPCAB. A postoperative improvement in the 
      cardiac functions and the quality of life was documented, increasing our 
      expectation for extensive application.
