Randomized Controlled Trial Comparative Study
Sustained supervised practice on a coronary anastomosis simulator increases medical student interest in surgery, unsupervised practice does not.
Given declining interest in cardiothoracic (CT) training programs during the last decade, increasing emphasis has been placed on engaging candidates early in their training. We examined the effect of supervised and unsupervised practice on medical students' interest in CT surgery. ⋯ Supervised training on low-fidelity simulators enhances interest in a career in surgery. Practice that lacks supervision does not, possibly related to the complexity of the simulated task. Mentorship efforts may need to involve sustained interaction to provide medical students with enough exposure to appreciate a surgical career.

Multicenter Study
Surgical management of neonatal atrioventricular septal defect with aortic arch obstruction.
For neonates with atrioventricular septal defect and aortic arch obstruction including coarctation of the aorta, we sought to determine whether a difference in outcomes exists after a primary neonatal versus staged surgical repair (neonatal arch repair with delayed intracardiac repair). ⋯ For neonates with atrioventricular septal defect and aortic arch obstruction, when compared with neonatal repair, a staged approach was associated with improved survival and lower morbidity.

Changes in health-related quality of life in off-pump versus on-pump cardiac surgery: Veterans Affairs Randomized On/Off Bypass trial.
The relative benefits of performing coronary artery bypass graft surgery off-pump versus on-pump continue to be debated. A critical, patient-centered outcome is health-related quality of life; yet there has been limited evaluation in large-scale, multicenter trials of the off-pump versus on-pump impact upon quality of life. ⋯ For this trial's male, low-to-moderate risk, veteran population, there were no significant differences between off-pump and on-pump with regard to 1-year general and disease-specific quality of life outcomes. Both treatment arms experienced some improvements by 3 months, with continued improvements through 1-year post-bypass.

Comparative Study
Surgical strategy for atrioventricular septal defect and tetralogy of Fallot or double-outlet right ventricle.
Tetralogy of Fallot, or double-outlet right ventricle with atrioventricular (AV) septal defect (TOF/DORV-AVSD), is rare, with limited long-term data available. We report our institutional experience and outcome over a 50-year period. ⋯ Complete repair of TOF/DORV-AVSD is standard of care and associated with low early mortality rate in the current era, with reasonable long-term outcome. SV palliation continues to have significant risk. The presence of AVV regurgitation is a significant risk factor for death and reoperation.

Comparative Study
Variation in warfarin thromboprophylaxis after mitral valve repair: does equipoise exist and is a randomized trial warranted?
There are limited data available to inform decision making regarding warfarin thromboprophylaxis early after mitral valve repair. ⋯ At present, half of patients are prescribed warfarin after isolated mitral valve repair in North American cardiac surgical practice which may impact the length of hospital stay. Although patient-level predictors of warfarin prescription exist, center- and surgeon-level variations are prominent. There is a pressing need for a randomized trial both to guide therapy and to ascertain the potential for resource conservation.
