Randomized Controlled Trial Comparative Study Clinical Trial
Intracoronary shunts reduce transient intraoperative myocardial dysfunction during off-pump coronary operations.
This study investigated the hemodynamic changes in patients undergoing multiple vessel beating heart coronary revascularization in the presence or absence of an intracoronary shunt. ⋯ Stabilization of the left anterior descending coronary artery to perform the anastomosis resulted in temporary hemodynamic changes, which are prevented by the use of an intracoronary shunt. The hemodynamic deterioration during the construction of the posterior descending coronary artery and circumflex coronary artery anastomoses is transient in the shunt group, whereas the snaring technique is associated with an impairment of early functional recovery.

Hospital readmission after coronary artery bypass grafting: are women doing worse?
In studies of gender effects on outcome after coronary artery bypass grafting, early mortality has consistently tended to be higher among women, whereas long-term results have varied. The aim of this study was to identify predictors of hospital readmission and assess the effect of gender. ⋯ This study showed an acceptable risk of readmission after coronary artery bypass grafting. Women more often had risk factors related to readmission. However, given identical disease severity, the risk was similar in men and women.

Review Comparative Study
Mechanical circulatory support for infants and children with cardiac disease.
Mechanical circulatory support is assuming an expanding role in the practice of congenital cardiac surgery. Extracorporeal membrane oxygenation and centrifugal ventricular assist devices are still the mainstay of mechanical circulatory support for children; however, newly developed pulsatile, paracorporeal ventricular assist devices designed for pediatric applications are achieving increased utilization. In addition, several new, continuous flow devices that are under development as fully implantable systems for adults, ultimately may be useful for pediatric patients.

Fistulous communication between the aorta and the pulmonary parenchyma developed in a 38-year-old woman 19 years after repair of a congenital aortic coarctation with Dacron patch aortoplasty. The fistula, inducing intermittent hemoptysis, arose from the suture line between the prosthetic fabric and the aorta. There was no infectious background or aneurysm at the primary repair site. The aortic segment including the prosthetic patch was resected and replaced with a Dacron tubular vascular prosthesis.
