Most coronary artery fistulas were reported as congenital. Acquired coronary artery fistula occurring after cardiac surgery has rarely been reported. ⋯ Acquired coronary artery fistula is a rare complication after cardiac surgery. Reoperation and resection of right ventricular hypertrophic muscle increase the risk of this complication. Although shunt flow did not increase during follow-up, the significance of acquired coronary artery fistula needs further investigation.

Comparative Study
Trends in incidence and mortality in the hospital diagnosis of atrial fibrillation or flutter in Denmark, 1980-1999.
The incidence of diagnosed atrial fibrillation is increasing in the USA, England, Wales, Scotland and Denmark, and the mortality rate in patients with diagnosed atrial fibrillation has been reported to be declining in Scotland and Denmark. We undertook this study to examine recent trends in incidence and mortality in subjects with a hospital diagnosis of atrial fibrillation or flutter in Denmark from 1980 to 1999 by sex, 10-year age group and conditions of comorbidity. ⋯ The incidence of a hospital diagnosis of atrial fibrillation or flutter more than doubled, and the 10-year age group- and comorbidity- and general population-adjusted mortality decreased, equally, from the first to the last 5-year period by 20% in men and 18% in women.

Comparative Study
Preoperative statin use and outcomes following cardiac surgery.
Cardiac surgery carries a 2-3% early mortality due in part to perioperative myocardial infarction (PMI), low-output syndrome (LOS), and arrhythmias. Statins attenuate thrombogenesis, normalize endothelial dysfunction, and mitigate the oxidative stress and reperfusion injury characteristic of such complications. We sought to determine whether preoperative statin use is associated with reduced early mortality and major morbidity following cardiac surgery. ⋯ Preoperative statin use is not associated with a reduction in IHM or major morbidity following cardiac surgery.
