Right atrial overdrive pacing does not prevent atrial fibrillation after coronary artery bypass surgery.

Aims: The purpose of this prospective randomized study was to investigate the efficacy of atrial overdrive pacing (AOP) and bradycardia prevention pacing (BPP) in the prophylaxis of atrial fibrillation (AF) after coronary artery bypass surgery (CABG).

Methods: One hundred and twenty-four on-pump CABG patients were randomized into three groups: AOP, BPP, and NP (no pacing). AOP patients were paced via epicardial wires using an atrial preference pacing algorithm, and BPP patients were paced in the AAI mode with a base rate of 60/min.

Angiographic predictors of graft patency and disease progression after coronary artery bypass grafting with arterial and venous grafts.

Background: There are few data about angiographic determinants of functional graft patency and native artery disease progression after coronary artery bypass grafting operation with arterial grafts compared with venous grafts.

Methods: Baseline and follow-up coronary angiograms at a mean of 2 years after operation in 91 patients with 194 arterial and 204 venous graft anastomoses were analyzed.

Results: Ninety-two percent of the arterial and 87% of the venous graft anastomoses were patent at follow-up angiography (p = 0.

Asymptomatic carotid artery occlusion from a gunshot. The role of angiography in penetrating neck trauma.

Recognition of a carotid artery injury after a gunshot neck wound can be difficult to make in the absence of physical signs. Currently, the usefulness of preoperative angiography in detecting penetrating neck trauma is controversial. We present a case of an angiography proven asymptomatic carotid artery occlusion after a gunshot.
