A 62-year-old man with coronary artery disease and ischemic cardiomyopathy after coronary artery bypass grafting and insertion of a HeartMate II (Thoratec, Pleasanton, CA) left ventricular assist device (LVAD) presented with spontaneous incisional bleeding and an ascending aortic pseudoaneurysm. Aortic angiography revealed an anomalous connection between the pseudoaneurysm and the LVAD conduit. We were able to partially embolize the tract with standard techniques, but the patient returned with repeated bleeding...

Percutaneous mechanical circulatory support devices, such as intra-aortic balloon pump (IABP), active left ventricular assist devices (LVAD) or extracorporeal life support (ECLS), are treatment options for selected patients in cardiogenic shock, undergoing cardiopulmonary resuscitation, or high-risk percutaneous coronary intervention and coronary artery bypass grafting. Potential benefits include the maintenance of organ function and the reduction of intracardiac pressures, volumes, and oxygen consumption. On the other hand, they are invasive, resource intensive, and can be associated with serious complications...

BACKGROUND: Mitral regurgitation (MR) is very rare in patients with type A dissection. We retrospectively reviewed our experience of total arch replacement (TAR) with mitral valve surgery for type A dissection with MR. METHODS: From November 2009 to October 2012, 14 patients with type A dissection (chronic = 11; acute = 3) with MR underwent TAR combined with mitral valve surgery under hypothermic cardiopulmonary bypass with selective cerebral perfusion. The Bentall procedure was performed in 11 patients, aortic valve replacement (AVR) in one patient, coronary artery bypass grafting (CABG) in three patients, and tricuspid valvuloplasty (TVP) in one patient...

The use of extracorporeal life support systems (ECLS) in patients with postcardiotomy low cardiac output syndrome (LCO) as a bridge to recovery and bridge to implantation of ventricular assist device (VAD) is common nowadays. A 59-year-old patient with acute myocardial infarction received a percutaneous transluminal angioplasty and stenting of the circumflex artery. During catheterization of the left coronary artery (LAD), the patient showed ventricular fibrillation and required defibrillation and cardiopulmonary resuscitation...

Coronary artery disease (CAD) involving the left main (LM) artery has traditionally been considered an indication for coronary artery bypass surgery (CABG). With recent advances in the field of percutaneous coronary interventions (PCI), angioplasty and stenting of the unprotected' LM has been performed in patients at high surgical risk. This is a challenging intervention as a large area of myocardium is at risk during the procedure. Features that make it especially high risk are distal stenosis of this vessel and presence of coronary disease in other territories...

Intra-aortic balloon pump (IABP) counterpulsation has been the most widely used left ventricular assist device for nearly five decades. Due to diastolic inflation and systolic deflation, coronary blood flow is increased and afterload decreased translating into augmentation of oxygen supply and lowering of oxygen demand. However, IABP may be associated with serious complications, including major bleeding, stroke, local and systemic infections and vascular complications. These might counterbalance the potential beneficial hemodynamic effects...

OBJECTIVE: We previously developed a native heart load control system for a continuous-flow left ventricular assist device and demonstrated that the rotational speed synchronized with the cardiac cycle can alter left ventricular preload and myocardial oxygen consumption. In the present study, we assessed this system in a conscious goat model of chronic heart failure. METHODS: Chronic heart failure was induced by coronary microsphere embolization of the left ascending artery and subsequent rapid ventricular pacing in 6 goats...

Patients with high-risk coronary lesions may be denied coronary artery bypass grafting due to excessive comorbidities. Percutaneous coronary intervention (PCI) may be a feasible revascularization strategy in high-risk patients who present with ST-elevation myocardial infarction and cardiogenic shock. Historically, the use if intra-aortic balloon pump (IABP) has been used in high-risk PCI and cardiogenic shock. However, recent data has shown that elective IABP insertion did not reduce the incidence of major cardiovascular events following PCI...

AIM: Postcardiotomy cardiogenic shock (PCCS) is associated with high mortality rates, despite full conventional treatment. Although the results of treatment with surgically implantable ventricular assist devices have been encouraging, the invasiveness of this treatment limits its applicability. Several less invasive devices have been developed, including the Impella system. The objective of this study was to describe our three-center experience with the Impella 5.0 device in the setting of PCCS...
