Multicenter StudyThe Society of Thoracic Surgeons Intermacs database annual report: Evolving indications, outcomes, and scientific partnerships.
The Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs), a joint effort among the National Heart, Lung, and Blood Institute, the Food and Drug Administration, the Centers for Medicare and Medicaid Services, and others, was established in 2005 at the University of Alabama at Birmingham. The registry examined clinical outcomes and quality-of-life metrics of patients who received an Food and Drug Administration-approved durable mechanical circulatory support (MCS) device to treat advanced heart failure. On January 1, 2018, the Intermacs Database became part of The Society of Thoracic Surgeons National Database, providing additional resources for quality assessment and improvement and scientific advancement. ⋯ With the evolution of MCS, patient phenotype and outcomes are also changing over time. CF LVAD support is increasingly being used in the less ill patient phenotype and more patients are supported for destination therapy. Mean survival is now approaching 5 years, but adverse events, especially neurologic events, continue to have a detrimental impact on the success of CF LVAD support.

Randomized Controlled Trial Multicenter StudySafety and tolerability of transition from inhaled treprostinil to oral selexipag in pulmonary arterial hypertension: Results from the TRANSIT-1 study.
A long-term trial showed that the oral prostacyclin (PGl2) receptor (IP) agonist, selexipag, delayed disease progression in patients with pulmonary arterial hypertension (PAH). Transition to selexipag in patients treated with more burdensome inhaled therapies that target the prostacyclin pathway may be considered by patients and physicians. The Phase 3b, prospective, open-label TRANSIT-1 (Tolerability and Safety of the Transition From Inhaled Treprostinil to Oral Selexipag in Patients With Pulmonary Arterial Hypertension) study evaluated the safety and tolerability of transition from inhaled treprostinil to oral selexipag. ⋯ NCT02471183.

Multicenter StudyAn international multicenter experience of biventricular support with HeartMate 3 ventricular assist systems.
Significant right ventricular failure accompanying left ventricular failure was treated by implantation of the fully magnetically levitated centrifugal HeartMate 3 ventricular assist device as biventricular (BiVAD) support in 14 patients at 6 medical centers worldwide. The clinical details of this first multicenter experience are presented. Nine of these patients (64%) were alive as of January 1, 2018. Eight of the 9 have continued on BiVAD support for 95 to 636 (mean 266) days: 7 at home, and 1 successfully transplanted after 98 days of support.

Multicenter StudyMulticenter experience with durable biventricular assist devices.
Severe right ventricular failure necessitating a right ventricular assist device (RVAD) complicates 6% to 11% of left ventricular assist device (LVAD) implants. Patient outcomes for those receiving durable continuous-flow VADs in a biventricular configuration (i.e., BiVAD) have been reported in limited case series. ⋯ Patients receiving durable BiVADs represent a critically ill patient population with severe biventricular failure who have high operative mortality and RVAD thrombosis rates. The 1-year survival for patients receiving contemporaneous BiVADs in experienced centers mirrors other contemporary durable biventricular support strategies.

Multicenter Study Observational StudyPrediction of potential for organ donation after circulatory death in neurocritical patients.
The success or failure of donation after circulatory death depends largely on the functional warm ischemia time, which is closely related to the duration between withdrawal of life-sustaining treatment and circulatory arrest. However, a reliable predictive model for the duration is absent. We aimed to compare the performance of the Chinese Donation after Circulatory Death Nomogram (C-DCD-Nomogram) and 3 other tools in a cohort of potential donors. ⋯ The C-DCD-Nomogram is superior to the other 3 tools for predicting death within a limited duration after withdrawal of life-sustaining treatment in Chinese neurocritical patients. Thus, it appears to be a reliable tool identifying potential donors after circulatory death.
