The CentriMag left ventricular assist system can be used for perioperative or postcardiotomy circulatory support of the failing heart. The device resides at the patient's bedside, and the cannulae are usually inserted through a midline sternotomy, with the inflow cannula in the left ventricle or right superior pulmonary vein and the outflow cannula in the(More)
IMPORTANCE Recent trials of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) for multivessel disease were not designed to detect a difference in mortality and therefore were underpowered for this outcome. Consequently, the comparative effects of these 2 revascularization methods on long-term mortality are still unclear. In(More)
BACKGROUND Postcardiotomy cardiogenic shock (PCS) is often fatal despite inotropic and circulatory support. We compared our experience with the CentriMag left ventricular assist device (LVAD) for patients with PCS at two time periods: in the operating room (OR) after unsuccessful weaning from cardiopulmonary bypass (CPB) and after transfer to the intensive(More)
BACKGROUND In patients with a left ventricular assist device (LVAD), pump-related infection can cause adverse effects that may result in death. METHODS We describe three patients who had infections related to a fistula between the gastrointestinal (GI) tract and the LVAD pocket and who subsequently underwent successful heart transplantation without(More)
Finding the source of a fungal infection and selecting the most appropriate treatment for candidemia is often challenging for physicians, especially when the patient has a complex medical history. We describe the case of a 48-year-old woman who had persistent candidemia after undergoing explantation of a left ventricular assist device. The source of the(More)
Pulmonary pneumatoceles are air-filled, thin-walled cavities that may develop within the lung parenchyma. Pneumatoceles typically develop as a complication of pneumonia, but they may also result from infections, trauma, or positive pressure ventilation. We describe the case of a patient with a left ventricular assist device for whom surgical resection of a(More)
Cardiovascular complications during or after transcatheter aortic valve replacement (TAVR) are associated with extremely high mortality, but extracorporeal membrane oxygenation (ECMO) can be used as procedural rescue option to improve outcomes when patients experience respiratory or cardiac arrest. From 2012 to 2014, 230 patients underwent TAVR and 10(More)
Left ventricular pseudoaneurysm is a rare lesion that occurs when a contained free-wall rupture occurs after a transmural myocardial infarction. Such a pseudoaneurysm may be lethal if subsequent rupture or progressive heart failure occurs. We describe a 67-year-old man who, one year after undergoing coronary artery bypass grafting, developed an(More)
A growing number of patients have undergone the Mustard procedure for transposition of the great arteries, after which the morphologic right ventricle serves as the systemic ventricle. If this ventricle fails, ventricular assist device support may be necessary, but implanting the inflow cannula can be challenging in these patients because of the moderator(More)
Diagnostic evaluation of embolic neurologic events requires the consideration of cardiac causes. We recently encountered a case that emphasizes the importance of cardiac tumor as a source of embolic events. We present herein the case of a 42-year-old woman who suffered a transient ischemic attack caused by a papillary fibroelastoma that originated from the(More)
