Two cases of coronary artery disease coexisting with abdominal aortic aneurysm were treated with off-pump coronary artery bypass grafting combined with repair of the aneurysm. The first patient was a 67-year-old man exhibiting a large pulsating abdominal mass. Abdominal computed tomography demonstrated a 9-cm aneurysm and coronary angiogram revealed a 90% stenosis of the obtuse marginal branch ...

OBJECTIVE To determine whether graft patency after on-pump and off-pump coronary artery bypass surgery is similar when performed using the same heparinization protocol. METHODS In a randomized, controlled, multicenter trial, 900 patients more than 70 years of age received either on-pump or off-pump coronary artery bypass surgery. Heparin was given to achieve an activated clotting time of 400 ...

In coronary artery surgery the superiority of the internal mammary artery graft in 10-year survival was documented in 1986. In 1999 it was demonstrated that death, reoperation and percutaneous transluminary coronary angioplasty were more frequent in patients undergoing single rather than bilateral internal mammary artery grafting. Today coronary artery bypass grafting surgery is challenged by t...

BACKGROUND The effect of the use of coronary-artery bypass surgery without cardiopulmonary bypass and cardiac arrest ("off pump") on graft patency remains uncertain. We undertook a prospective, randomized, controlled study to compare graft-patency rates and clinical outcomes in off-pump surgery with conventional, "on-pump" surgery. METHODS We randomly assigned 50 patients to undergo on-pump c...

The development of new mechanical stabilizer in the market encouraged a lot of surgeons to practice offpump coronary artery bypass as this procedure avoids all the possible risks of cardio-pulmonary bypass, an essential element in the conventional coronary bypass operations. During a period of 50 months, the cardiac surgery unit in King Khalid University Hospital performed 85 cases of off-pump ...

the term “stunned myocardium” refers to abnormalities in the myocardial function following reperfusion and is common in on-pump coronary artery bypass grafting (cabg) and is exceedingly rare in off- pump cabg. a 53-year-old man presented with unstable angina due to the severe stenosis of the left anterior descending coronary artery (lad) and the obtuse marginal. laboratory findings and chest x-...

Twelve years after receiving a renal transplant, a 50-year-old woman developed asthmatic symptoms. Chest CT revealed a descending thoracic aortic aneurysm. She had undergone percutaneous coronary intervention to treat the left anterior descending artery 10 years earlier. Coronary artery angiography revealed restenosis of the left anterior descending artery (99%, #6 in-stent). Because cardiopulm...
