Comparative Study
Impact of preoperative anemia on outcome in adult cardiac surgery: a propensity-matched analysis.
Preoperative anemia is not considered an operative mortality risk factor by the majority of the risk stratification tools used in cardiac surgery. However, retrospective studies have found associations between preoperative anemia and morbidity and mortality in cardiac operations. The present study compares the postoperative outcome of a group of moderate-to-severe anemic patients with a propensity-matched group of nonanemic patients undergoing cardiac operations. ⋯ Moderate-to-severe preoperative anemia is a risk factor for major morbidity and operative mortality in adult cardiac operations. This finding is confirmative of the role of preoperative anemia in determining adverse events in major noncardiac operations. The exclusion of preoperative anemia from the existing risk scores is probably a statistical consequence of the associated comorbid conditions that confound the specific role of anemia as a risk factor.

Case Reports
Three-dimensional transesophageal echocardiography of a thrombus entrapped by a patent foramen ovale.
The substrate of paradoxic embolization is a patent foramen ovale allowing right-to-left passage of embolic material. A thrombus in transit entrapped by a patent foramen straddling an atrial septal aneurysm is an exceedingly transient condition rarely documented on imaging studies. ⋯ Intraoperative real-time three-dimensional transesophageal echocardiography allowed accurate spatial characterization of the thrombus and correlated closely with surgical findings. It provided more realistic intraoperative guidance compared with conventional two-dimensional transesophageal echocardiography.

An interventional lung assist membrane ventilator (iLA) for arteriovenous extracorporeal CO2 removal was connected to a small-diameter femoral artery by use of a chimney graft in an underweight patient with acute respiratory failure and a previous history of heart-lung transplantation. This concept offers additional therapeutic options in underweight patients requiring extracorporeal CO2 removal with arterial vessels that are too small for percutaneous arterial cannulation with standard-sized percutaneous insertable iLA cannulae.

Case Reports
Surgical repair of a left atrial-esophageal fistula after radiofrequency catheter ablation for atrial fibrillation.
Left atrial-esophageal fistula is a highly lethal complication of ablative therapy for atrial fibrillation. Because of its unusual rate of occurrence, there has not been a uniform approach to either the diagnosis or corrective therapy. We offer 1 such surgical option based on presumptive and early diagnosis-left atrial repair with cardiopulmonary bypass followed by repair of the esophagus with an omental wrap and supported with decompressive gastrostomy and feeding jejunostomy.

Most cases of blunt cardiac rupture (BCR) are associated with mortality at the scene of the injury. For the fortunate 13% to 17% of patients who survive the journey to the hospital, the treatment is definitive surgical repair. ⋯ We describe a patient who sustained 2 right ventricular tears from blunt trauma in a motor vehicle accident 18 years after coronary artery bypass graft surgery. He did not demonstrate hemodynamic compromise and was successfully managed conservatively.
