Advanced heart failure is a rare but important complication of hypertrophic cardiomyopathy (HCM). The only definitive treatment is heart transplantation and the role of ventricular assist devices remains uncertain. We describe the use of implantable biventricular assist devices in the treatment of a patient with 'end-stage' non-dilated HCM.

Heart failure (HF) is a complex clinical condition with symptoms that result from ineffective ejection of blood due to functional or structural impairment of the heart. The most common causes of HF include ischemic heart disease, myocardial infarction (MI), hypertension, and valvular heart disease (VHD). As HF progresses to advanced stages, interventions, like left ventricular assist devices (LVADs), become essential, especially for patients ineligible for heart transplantation.

Background: The study assesses the feasibility of the DuoCor BiVAS, a novel biventricular assist system integrating magnetic levitation technology.
Methods: In an acute large animal model involving five sheep, each received the DuoCor BiVAS without cardiopulmonary bypass. Hemodynamic and device parameters were monitored continuously for 1-h post-implantation.

Objective: After Fontan palliation, patients with single-ventricle physiology are committed to chronic circulatory inefficiency for the duration of their lives. This is due in large part to the lack of a subpulmonary ventricle. A low-pressure rise cavopulmonary assist device can address the subpulmonary deficit and offset the Fontan paradox.

Background: Cardiovascular magnetic resonance (CMR) is the gold-standard to estimate right ventricular (RV) volumes, which are key for clinical management of patients with repaired tetralogy of Fallot (rTOF). Semi-automated threshold-based methods (SAT) have been proposed for CMR post-processing as alternatives to fully manual standard tracing. We investigated the impact of SAT on RV analysis using different thresholds in rTOF patients.
