Comparative Study
Is body mass index a risk factor for isolated off-pump coronary revascularization?
The influence of body mass index (BMI) as a risk factor for isolated off-pump coronary artery bypass (OPCAB) surgery is unknown. We postulated that BMI ≥ 30 kg/m(2) would adversely affect outcomes following OPCAB at our institution. ⋯ Obesity does not influence operative characteristics or effect outcomes after OPCAB. BMI ≥ 30 kg/m(2) should not be considered a prohibitive risk factor in isolated off-pump coronary revascularization.

Valve deterioration following aortic valve replacement using the Freestyle stentless bioprosthesis is related to cusp tear, operative injury, or infection. We report a patient with aortic regurgitation due to perforation of the right coronary cusp 10 years after implantation of a Freestyle stentless bioprosthesis in the absence of endocarditis.

Case Reports
Echocardiographic diagnosis and surgical closure of coronary sinus type of atrial septal defect.
Coronary sinus type of atrial septal defect (ASD CS) is a rare cardiac anomaly and is rarely diagnosed by only transthoracic echocardiography prior to surgical operation. We now describe a technique to treat this defect with the aid of two-dimensional echocardiography, which prevents trauma to the conduction system and maintains drainage from the coronary sinus into the right atrium (RA).
