Sleeve Gastrectomy and Left Ventricular Assist Device for Heart Transplant

BACKGROUND AND OBJECTIVES Heart failure (HF) is a severe obesity-related comorbidity. Many patients with end-stage HF eventually require cardiac transplantation for long-term survival. These patients may be precluded from enrollment in heart transplant programs secondary to morbid obesity. We propose a pathway involving sleeve gastrectomy (SG) for patients with morbid obesity and HF to afford c...

Pre-explant stability of unloading-promoted cardiac improvement predicts outcome after weaning from ventricular assist devices.

BACKGROUND Detection of cardiac recovery that allows long-term cardiac stability after ventricular assist device (VAD) explantation is a major goal. After normalization of ventricular diameters during unloading, the pre-explant left ventricular ejection fraction (LVEF) allows the detection of patients with the potential to remain stable after VAD explantation. However, some patients with LVEF >...

Ventricular Assist Device-Specific Infections

Ventricular assist devices (VADs) have been shown to offer a significant survival benefit over medical therapy in patients with advanced heart failure. Despite significant advances in device technology and surgical technique, VAD-specific infections still remain among the most common causes of morbidity and mortality in patients with VADs. VAD-specific infections may involve the driveline exit ...

Improvement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization

In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...
