The aim of this study was to examine the impact of prolonged intensive care unit (ICU) stay on in-hospital mortality and long-term survival. ⋯ Prolonged ICU stay is an important predictor of adverse immediate, short-term, and long-term outcomes after cardiac operations.

Acute kidney injury requiring renal replacement therapy (RRT) is associated with increased mortality after cardiac surgery. Studies examining the impact of RRT after lung transplantation (LTx) are limited. We evaluated risk factors and outcomes associated with RRT after LTx. ⋯ In the largest study to evaluate acute kidney injury after LTx, the incidence of RRT is 5.51%. The need for post-LTx RRT dramatically increases both short- and long-term mortality. Several variables, including preoperative renal function, are predictors of post-LTx RRT and could be used to identify transplant candidates at risk for acute kidney injury.

Although commonly reserved as a last line of defense, experienced centers have reported excellent results with pulmonary embolectomy for massive and submassive pulmonary embolism (PE). We present a contemporary surgical series for PE that demonstrates the utility of peripheral extracorporeal membrane oxygenation (pECMO) for high-risk surgical candidates. ⋯ Heparin therapy with pECMO support is a rapid, effective option for patients who might benefit from pulmonary embolectomy but are at high risk for surgery.

Morbid obesity is associated with increased resource utilization in coronary artery bypass grafting.
Studies have shown good outcomes for morbidly obese patients who undergo cardiac surgery. However, little is known about how much additional resource utilization treating these challenging patients requires. We hypothesized that morbidly obese patients (body mass index ≥40 kg/m(2)) undergoing coronary artery bypass grafting needed longer operating room times and had longer hospital and intensive care unit stays than non-morbidly obese patients. ⋯ Although good outcomes can be achieved for morbidly obese patients who undergo coronary artery bypass grafting, these patients require considerably more resource utilization in the operating room and intensive care unit, and they spend more time in the hospital after surgery. At a cardiac surgical operating room cost of approximately $50 per minute and $4,500 per intensive care unit day, the financial implications for morbidly obese patients who need coronary artery bypass grafting are not insignificant.

Few data are available on the clinical outcome of patients with acute coronary syndrome (ACS) complicated by refractory cardiogenic shock or cardiac arrest who receive percutaneous extracorporeal life support (ECLS). We investigated the in-hospital outcome and predictors of mortality in these patients. ⋯ Despite hemodynamic support with ECLS, patients with ACS complicated by cardiogenic shock or cardiac arrest refractory to conventional treatment had high mortality. However, the higher than 30% in-hospital survival rate in this extremely critical population indicates that ECLS might improve outcomes in ACS by saving the lives of patients in this specialized category. Unsuccessful angioplasty, asystole or pulseless electrical activity before ECLS introduction, and ECLS-related complications were predictors of in-hospital mortality.
