OBJECTIVES: The study reports for the first time the 30-day outcomes of the first U.S. study with the Cardioband tricuspid valve reconstruction system for the treatment of functional tricuspid regurgitation (TR). BACKGROUND: Increasing severity of TR is associated with progressively higher morbidity and mortality; however, treatment options for isolated significant disease are limited. METHODS: In this single-arm, multicenter, prospective Food and Drug Administration-approved early feasibility study (EFS), 30 patients with severe or greater symptomatic functional TR were enrolled who were deemed candidates for transcatheter tricuspid repair with the Cardioband tricuspid system by the local heart team and multidisciplinary screening committee. RESULTS: The mean patient age was 77 years, 80% were women, 97% had atrial fibrillation, 70% were in New York Heart Association functional class III to IV with mean left ventricular ejection fraction of 58%, and 27% had severe, 20% massive, and 53% torrential TR. Device success was 93% and all patients were alive at 30 days. Between baseline and 30 days, septolateral tricuspid annular diameter was reduced by 13% (p < 0.001), 85% of patients had ≥1 grade TR reduction and 44% had ≤moderate TR, 75% were in New York Heart Association functional class I to II (p < 0.001), and overall Kansas City Cardiomyopathy Questionnaire score improved by 16 points (p < 0.001). CONCLUSIONS: In patients with severe symptomatic functional TR, this is the first study in the United States with the Cardioband tricuspid system for direct transcatheter annular reduction. This early feasibility study demonstrates high procedural feasibility with no 30-day mortality. There is significant reduction of functional TR with clinically significant improvements in functional status and quality of life.

The cardiac intensive care unit (CICU) has changed considerably over time and now serves a unique patient population with a high burden of cardiovascular and noncardiovascular critical illness. Patient complexity and technological evolutions in the CICU have catalyzed the development of critical care cardiology, a fledgling discipline that combines specialization in cardiovascular diseases with knowledge and experience in critical care medicine. Numerous uncertainties and challenges threaten to stymie the growth of this field. A multidisciplinary dialogue focused on the best care design for the CICU patient is needed as we consider alternative approaches to clinical training, staffing, and investigation in this rapidly evolving arena.
