Right ventricular (RV) failure is associated with poor outcome and increased mortality in cardiac surgery. Aim of our study was to analyze the outcome of veno arterial extracorporeal membrane oxygenation (va ECMO) therapy in patients with isolated RV failure in postcardiotomy cardiogenic shock (PCS) and to evaluate risk factors associated with 30-day-mortality. ⋯ ECMO therapy in RV failure due to PCS is shown to be associated with an excessive mortality. Regarding our data, va ECMO might only be an appropriate short-term mechanical assist device separating patients form cardiopulmonary bypass with an acceptable weaning rate. Particularly, in case of failed hemodynamic recovery of the right heart on va ECMO, direct RV bypass systems might function as a bailout option. Additionally, cardiac enzymes and lactic acid might provide valuable information in meeting therapy-related decisions.

Few studies have evaluated preoperative respiratory muscle strength as a risk factor for postoperative morbidity and mortality. The objective of this study was to evaluate the association of preoperative inspiratory muscle weakness (IMW) and preoperative expiratory muscle weakness (EMW) with duration of mechanical ventilation, length of stay in the intensive care unit (ICU), incidence of postoperative pulmonary complications (PPCs), and mortality in patients undergoing elective cardiac surgery. ⋯ In patients undergoing elective cardiac surgery, preoperative IMW is associated with the duration of mechanical ventilation while preoperative EMW is associated with a decrease in PPCs.

We sought to determine the indications, type, and outcomes of reoperations on the aortic root after repair of tetralogy of Fallot (TOF). ⋯ Reoperations on the aortic root are infrequent but may become necessary late after TOF repair. The main indications for reoperation are aortic insufficiency, either isolated or associated with a dilatation of the ascending aorta. The surgical risk at reoperation was high and the presence of ascending aorta dilation is related to higher mortality.

Surgical aortic valve replacement (SAVR) is the most common valvular surgery and thus needs to be widely available including minorities and socially disadvantaged patients. SAVR outcomes at safety-net hospitals, which serve a high percentage of these patients, are limited. We aimed to compare the outcomes of SAVR at different safety-net burden hospitals. ⋯ SAVR outcomes are reassuring at MBHs and HBHs.

Minimally invasive cardiac surgery (MICS) has expanded during the recent years due to interest in improved patient satisfaction and decreased stay in the hospital. To assist in these interests, postoperative pain control is aimed at decreasing opioid usage but maintaining adequate pain control. Regional anesthesia has the ability to provide these goals. This review article will describe different regional anesthesia techniques and discuss the evidence of their use in MICS. ⋯ As cardiac surgery moves toward smaller incisions and MICS with the goal of enhanced recovery, multimodal analgesic techniques should be explored for postoperative pain control. The regional techniques discussed in this article show a trend toward improved pain control and decreased stay in the intensive care unit.
