Patients with double inlet left ventricle (DILV)/transposition and similar morphologies have their systemic outflow traverse a bulboventricular foramen (BVF), which has a propensity to narrow over time. The aim of this study is to evaluate the outcomes of initial pulmonary artery banding (PAB) compared with the Norwood-type reconstruction in neonates. ⋯ The Norwood-type reconstruction provides good palliation in this subgroup of patients and avoids the need for subsequent intracardiac operations, maintaining an unobstructed systemic outflow tract and avoiding the risk of heart block. Survival does not differ depending on the type of procedure. Patients with PAB show comparable satisfactory early and long-term results, with an increasing reoperation risk and heart block remaining a major concern.

Postoperative atrial fibrillation (POAF) is a known predictor of in-hospital morbidity and short-term survival after coronary artery bypass grafting (CABG). The impact of race and long-term survival has not been examined in this population. We aimed to examine the influence of these factors on long-term survival in patients undergoing CABG. ⋯ Black race was a statistically significant predictor of decreased survival among POAF patients after CABG. This finding provides useful outcome information for surgeons and their patients.

Comparative Study
Clinical differences between continuous flow ventricular assist devices: a comparison between HeartMate II and HeartWare HVAD.
The HeartWare ventricular assist device (HVAD) is a new generation centrifugal flow VAD recently introduced in Canada. The objective of this study was to compare the HVAD device to the HeartMate II (HMII) axial flow device. Very few studies have compared clinical outcomes between newer generation VADs. ⋯ While device complications were comparable, patients with HVAD experienced a significantly higher incidence of stroke and GI bleeding and therefore refinement in patients' management may decrease incidence of these complications.

Transcatheter aortic valve replacement (TAVR) is performed as a stand-alone procedure in patients that are not suitable for surgical aortic valve replacement. However, a significant proportion of patients with severe aortic stenosis have coexisting coronary artery disease (CAD). We report concomitant TAVR and percutaneous coronary intervention (PCI) as a single procedure in such patients. ⋯ In our small series of patients presented we demonstrate that PCI and TAVR performed concurrently in the hybrid operating room is a feasible option in patients undergoing TAVR with coexisting CAD. Furthermore, we propose this single-stage approach in such high-risk patients as it decreases the number of procedures performed and may theoretically lower cost and hospital stay.

In spite of being a less-invasive technique, transcatheter aortic valve implantation (TAVI) remains associated with potential serious complications. Left ventricular pseudoaneurysm (LVP) is a known, serious complication of transapical TAVI. However, this complication has not been described after the trans-femoral approach. We describe a case of LVP after transfemoral TAVI, emphasizing the importance of an immediate diagnosis of this potential life-threatening complication.
