The axillary artery is an established alternative cannulation site for peripheral cardiopulmonary bypass (CPB). However, axillary vein cannulation is not as common. Here, we present our experience with an axillo-axillary CPB combined with a femoro-femoral CPB in redo aortic root replacement. ⋯ Cerebral protection could be achieved in both antegrade and retrograde fashion when the circulatory arrest was required for an additional arch procedure. Our strategy based on axillo-axillary and femoro-femoral CPB was effective and feasible in redo aortic root replacement. We consider that it simplified the complex aortic reoperation.

Less-invasive techniques for left ventricular assist device (LVAD) implantation have shown promising outcomes but are associated with significant postoperative pain. We aim to investigate the use of ultrasound-guided regional nerve blocks to improve pain management during these procedures. ⋯ Optimizing postoperative analgesia using a regional nerve block is associated with decreased opioid use and decreased postoperative pain after CSS LVAD implantation. Regional nerve blocks should be included as part of a protocol-based postoperative pain management program.

Case Reports
The role of surgical transcatheter valve implantation for the treatment of severe mitral annular calcification.
With a rise in the aging population, mitral annular calcification is increasingly encountered with an incidence of 10% in over 70 years old. This with increasing patient comorbidities presents a technical challenge due to the risk of atrioventricular disruption which is associated with high operative mortality of up to 75%. We describe two cases of severe mitral disease with marked annular calcification successfully treated with a balloon expandable transcatheter valve which was deployed on cardiopulmonary bypass via a trans-atrial approach.

Meta Analysis Comparative Study
Bilateral versus single internal thoracic artery for coronary artery bypass grafting with end-stage renal disease: A systematic review and meta-analysis.
The incidence of severe coronary artery disease (CAD) in patients with end-stage renal disease (ESRD) on dialysis is high. Coronary artery bypass grafting (CABG) is the preferred treatment in those with severe CAD. Bilateral internal thoracic artery (BITA) vs single internal thoracic artery (SITA) grafting has been shown to improve late survival in other high-risk populations. In ESRD, comparative studies are limited by sample size to detect outcome differences. We sought to determine the late survival and early outcomes of BITA compared with SITA in patients with ESRD. ⋯ BITA grafting is safe in patients with ESRD although there was no survival benefit at 3.7 years. Additional studies with longer follow-up are required to determine the potential late benefits of BITA grafting in patients with ESRD.

Observational Study
Outcomes after extracorporeal life support for postcardiotomy cardiogenic shock.
Extracorporeal life support (ECLS) may be necessary in refractory postcardiotomy cardiogenic shock (PCS) unresponsive to optimal medical treatment. We sought to analyze the results and temporal outcomes of ECLS for PCS. ⋯ Outcomes following ECLS remained stable over an 11-year period. ECLS may be limited in patients with severe preoperative cardiac dysfunction. Our data suggest that these patients may be better served with less invasive, percutaneous procedures.
