Abstract

We performed early postoperative angiography to assess anastomosis accuracy and patency after off-pump coronary artery bypass grafting. One thousand three hundred forty-five patients who underwent off-pump coronary artery bypass grafting between January 1998 and December 2007 were studied. Grafts for distal anastomoses were left internal thoracic artery (n=1281), right internal thoracic artery (n=679), right gastroepiploic artery (n=836), radial artery (n=14), and saphenous vein (n=188). Groups underwent off-pump coronary artery bypass grafting without (group I, n=234) or with (group II, n=1111) intraoperative graft flowmetry. Early postoperative (< or = 7 days) angiography was performed in 1278 cases (95.0%) at 1.6+/-1.2 postoperative days. Operative mortality was 1.6%. Average number of distal anastomoses was 3.0+/-1.0. Postoperative angiography showed early patencies of 98.9% for arterial grafts and 88.2% for venous grafts (P < .001). In group II, intraoperative flowmetry-guided revision was performed in 2.2% of distal anastomoses. Patency of arterial grafts was significantly higher in group II than group I (97.2% vs 99.1%, P < .001); however, patency of venous grafts was not significantly different (86.0% vs 92.2%, P=.099)....Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Antianginal Drugs: Mechanisms of Action

Antianginal drugs, including nitrates, beta-blockers, and calcium channel blockers, are used in the treatment of angina pectoris. Here is the latest research on their use and their mechanism of action.
