Abstract

The use of cardiopulmonary bypass (CPB) may contribute to post-operative complications and organ dysfunction. Off pump coronary artery bypass grafting (OPCABG) avoids the use of CPB and hence is proposed to reduce these complications. We present the results of OPCABG in Northern Ireland over ten years. Data was collected retrospectively from 1995 to 2005. Follow-up was done by telephonic questionnaire and from medical records within a closing interval of two months. 324 patients (224 male) underwent OPCABG with a median age of 62 years (range 35 to 79 years). There were 149 patients with CCS class III/IV angina and 48 with NYHA class III/IV. 148 patients had suffered a myocardial infarction in the past. 36 patients had a pre-operative predictive mortality score (EuroSCORE) of >5 and 48 patients had a preoperative LVEF of <30%. 585 bypass grafts were constructed (LAD=260, Diagonal=27, LCX/OM=123, RCA/PDA=103, RCA/PLV=72). Four patients needed to be converted from OPCABG to CPB on table. Another four patients needed re-operation due to graft related problems in the post-operative period and 6 needed post-operative Intra-aortic Balloon Pump (IABP) support. Post-operative complications included 3 TIAs, 1 complete stroke, 9 patients...Continue Reading

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

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.

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.
