Multicenter Study Comparative Study
Postoperative inotrope and vasopressor use following CABG: outcome data from the CAPS-care study.
Limited clinical data exist to guide practice patterns and evidence-based use of inotropes and vasopressors following coronary artery bypass grafting (CABG). ⋯ While considerable variability is present among hospitals in inotrope use following CABG, observational comparison of outcomes did not distinguish a superior pattern; thus, randomized prospective data are needed to better guide clinical practice.

A 60-year-old femalepresented with progressive dysphagia and was found to have a right-sided aortic arch with external posterior compression of the upper esophagus due to severe compression from a Kommerell's diverticulum with an aberrant left subclavian artery. This patient underwent division of the diverticulum with an aorto-subclavian graft implantation under femoro-femoral bypass and recovered uneventfully. A review of the literature and discussion of the surgical management is presented.

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.

Comparative Study
Left internal thoracic artery composite grafting with the right internal thoracic versus radial artery in coronary artery bypass grafting.
The aim of this study was to compare the results of all arterial multivessel coronary artery bypass grafting using the left internal thoracic artery composite bypass graft constructed with the right internal thoracic artery or radial artery. ⋯ Although superior patency was observed with the right internal thoracic artery over the radial artery graft, a significant commensurate benefit in reducing the incidence of major adverse clinical outcomes was not necessarily shown.

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.
