BACKGROUND Heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication of heparin administration. It can present a major clinical dilemma for physicians caring for patients requiring life-saving urgent or emergent cardiac surgery. Studies have been published examining the use of alternative anticoagulants for patients undergoing cardiopulmonary bypass (CPB), however, evidence does not clearly support any particular approach. Presently, there are no large-scale, prospective randomized studies examining the impact of alternative anticoagulants on clinical outcomes for HIT-positive patients requiring cardiac surgery...

Advanced percutaneous and surgical procedures in structural and congenital heart disease require precise pre-procedural planning and continuous quality control. Although current imaging modalities and post-processing software assists with peri-procedural guidance, their capabilities for spatial conceptualization remain limited in two- and three-dimensional representations. In contrast, 3D printing offers not only improved visualization for procedural planning, but provides substantial information on the accuracy of surgical reconstruction and device implantations...

BACKGROUND: Diastolic pressure gradient (DPG) of ≥7 mmHg has been proposed to distinguish mixed pulmonary hypertension from isolated post-capillary pulmonary hypertension in heart failure (HF). We evaluated the changes in pulmonary hemodynamics with left ventricular assist devices (LVADs) in patients with DPG of ≥7 or <7 mmHg, and effects on peak oxygen uptake (VO2) in patients with advanced HF. METHODS: Pre- and post-LVAD implant pulmonary hemodynamics (including right atrial (RA) pressures, DPG, pulmonary vascular resistance (PVR), pulmonary capacitance (PCap) and cardiac output), echocardiography, cardiopulmonary exercise test were measured in 38 consecutive patients...

OBJECTIVES: To assess safety and clinical performance of a novel bioabsorbable vascular graft in pediatric patients with univentricular cardiac malformation who received surgical correction via an extracardiac cavopulmonary conduit. METHODS: The implanted graft material is designed to attract patient's own cells and proteins, which trigger a cascade of physiological events leading to endogenous tissue restoration. As the graft resorbs progressively after implantation, components of native tissue including collagen, endothelial lining, and capillary blood vessels develop and organize into a natural tissue...

Right ventricular failure (RVF) affects up to 50% of patients post-left ventricular assist device (LVAD) implantation, and carries significant morbidity and mortality. There is no widely-used long-term mechanical support option for the right ventricle, thus early identification, prevention and medical treatment of RVF is of the upmost importance. Areas covered: A PubMed search was first completed searching "Right ventricular failure post-LVAD" which yielded 152 results, and a subsequent search was performed under "RV mechanical support" which yielded 374 results, and was filtered to "humans" and literature written in English, generating 219 results...
