Mitral valve regurgitation (MR) causes blood to flow in two directions during contraction of the left ventricle (LV), that is, forward into the aorta and backward into the left atrium (LA). In aortic valve regurgitation (AR), leakage occurs from the aorta into the LV during diastole. Our objective is to analyze the contribution of a left ventricular assist device (LVAD) to MR and AR for the fol...

Patients with left ventricular assist devices (LVADs) are at high risk of sustained ventricular arrhythmias, but these may be remarkably well tolerated and the association with sudden death is unclear. Many patients who receive an LVAD already have an implantable cardioverter defibrillator (ICD). While it is standard practice to reactivate a previously implanted ICD in an LVAD recipient, this s...

Heart failure (HF) is a potentially fatal disease that affects increasing number of people worldwide. Although heart transplant is the "gold standard" therapy for HF, due to the limited availability of organs, many patients died when waiting for the transplant. Left ventricular assist device (LVAD), as a mechanical circulatory support, has become a new light for patients with HF. With the techn...

BACKGROUND Heart failure is associated with prolonged stress and inflammation characterized by elevated levels of cortisol and circulating catecholamines. Persistent sympathetic stimulation secondary to the stress of heart failure causes an induced insulin resistance, which creates a need for higher doses of insulin to adequately manage hyperglycemia in this patient population. We hypothesized ...

LVAD is a mechanical pump supporting a weak heart function and blood flow. Sometimes, the heart may not recover fast enough to take over the pumping action immediately after surgery, in such patients a temporary support device has been employed to maintain the pumping action until the patient’s own heart recovers. This device can be considered as a temporary alternative before the process of ar...

Patent foramen ovale (PFO) may complicate left ventricular assist device (LVAD) therapy. We report a 70-year-old male with a HeartMate II LVAD at increased risk for thromboembolic stroke secondary to a PFO with right-to-left shunting and a large mobile thrombus on his right atrial pacing lead. Via percutaneous intervention, a 25 mm Cribiform Amplatzer atrial septal occluder was successfully dep...

A young man with Duchenne muscular dystrophy presented to the UT Southwestern Neuromuscular Cardiomyopathy Clinic with advanced heart failure. Despite maximal medical therapy, his cardiac function continued to decline requiring initiation of inotrope therapy. Given the patient's clinical deterioration, a left ventricular assist device (LVAD) was implanted as destination therapy after undergoing...

BACKGROUND How caregivers contribute to positive or negative outcomes for left ventricular assist device (LVAD) patients remains unclear. Our primary study objectives were to (1) identify caregiver support attributes through a retrospective chart review of social workers' psychosocial assessments for LVAD patients and (2) determine how these attributes associated with patients' post-LVAD placem...

To the best of our knowledge this is the first case of this nature described in the literature. Sharing the authors experience with this case, particularly the technical challenges and post-operative management may aid other physicians facing similar scenarios. In this report, we describe a pancreaticoduodenectomy for pancreatic adenocarcinoma in a patient with a previous left ventricular assis...

The 2013 International Society for Heart and Lung Transplantation Guidelines for Mechanical Circulatory Support emphasize the importance of caregiver support for left ventricular assist device (LVAD) placement, recommending that a lack of support should serve as a relative contraindication to device placement. Despite the integral role that caregivers are expected to play, findings from studies...
