Abstract

To determine whether cut and sew Cox maze III procedure is still associated with adequate safety endpoints when performed in conjunction with other open-heart procedures. Between January 2008 and January 2015, 113 consecutive adult patients were submitted to cut and sew Cox maze III procedure in association with other operations for structural heart disease. Mean age was 49 years and 80 (70.8%) were females. Longstanding or persistent atrial fibrillation has occurred in 87.6% and rheumatic heart disease in 80.7%. Valve surgery was performed in 98.2%. The number of associated procedures was correlated with morbidity and hospital mortality. Overall mean cardiopulmonary bypass and aortic cross-clamping times were 129 ± 26 and 105 ± 23 minutes, respectively. Hospital mortality was 1.77%, re-exploration for bleeding 0.9%, cerebrovascular accident 1.8%, and acute renal failure requiring hemodialysis 2.6%. The greater number of associated procedures did not correlate with poorer safety outcomes. Permanent pacemaker was required in 18.2% of those with three associated procedures, as opposed to 4% with two procedures and no requirement with one procedure (P = .01). Frequency of sinus rhythm was 88%, 88%, and 85% at 6, 12, and 24 months,...Continue Reading

Atrial Filbrillation

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.
