Using MR scans and computational fluid dynamics, the authors sought to evaluate differences in flow, shear stress, and oscillatory shear stress in normal individuals and patients with 1 of 4 different categories of aortic valvular disease. The flow patterns were patient and category specific, and may provide the ability to determine interventions on an individualized basis.

The authors randomized 68 patients undergoing CABG to three treatment groups:
- ASA 81 mg QD
- ASA 325 mg QD
- ASA 162 mg BID
On the 4th day following CABG, the authors measured serum thromboxane B2 (TXB2) as an inverse surrogate for ASA effect. The order of TXB2 levels were as follows: 162 mg BID << 81 mg BID ≈ 81 mg QD. Thus, the optimal regimen, according to this small study, would be ASA 162 mg BID.

31 pts who underwent arterial switch at a weight of 2.5 kg or less were evaluated for outcomes. Surgery was performed at an average of 16 days of life. Mortality was 2.8% for those weighing 2.0-2.5 kg, and was 50% for those under 2 kg. At a mean follow-up of 13 years, 8% had required late reoperation. There were no late deaths, and all pts were NYHA Class I at last follow-up.

The authors describe a 10-year experience with extended arteriotomy for endarterectomy of a diffusely diseased LAD, using an internal mammary artery for reconstruction. Perioperative mortality was 1.1% and postoperative MI occurred in 9%. Survival at 5 years was 89% and freedom from acute cardiovascular events was 74%.
