Severe tricuspid regurgitation (TR) is a common problem, affecting approximately 1.6 million Americans, with the majority (85%) of TR being functional in nature. When left untreated, TR is associated with progressive right-sided heart failure, with a poor prognosis entailing high morbidity and mortality. Surgical repair is still the gold standard for TR, but only a small proportion of patients undergo surgical repair leaving a high clinical demand for alternatives to conventional surgery. Percutaneous repair and replacement of cardiac valves have exponentially advanced in the past decade, including transcatheter tricuspid valve repair. There are still anatomical challenges that need to be addressed when performing a percutaneous transcatheter annuloplasty compared to a surgical annuloplasty, such as approach, access, landing zone, proximal structures and visibility. Current percutaneous annuloplasty systems either obtain a direct (Cardioband) or indirect (TriCinch and Trialign) annuloplasty. Both direct and indirect percutaneous annuloplasties are modeled after surgical experiences. This review will investigate novel direct and indirect transcatheter annuloplasty devices for repair of severe tricuspid regurgitation.

UI MeSH Term Description Entries
D011379 Prognosis A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations. Prognostic Factor,Prognostic Factors,Factor, Prognostic,Factors, Prognostic,Prognoses
D006328 Cardiac Catheterization Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures. Catheterization, Cardiac,Catheterization, Heart,Heart Catheterization,Cardiac Catheterizations,Catheterizations, Cardiac,Catheterizations, Heart,Heart Catheterizations
D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION. Cardiac Failure,Heart Decompensation,Congestive Heart Failure,Heart Failure, Congestive,Heart Failure, Left-Sided,Heart Failure, Right-Sided,Left-Sided Heart Failure,Myocardial Failure,Right-Sided Heart Failure,Decompensation, Heart,Heart Failure, Left Sided,Heart Failure, Right Sided,Left Sided Heart Failure,Right Sided Heart Failure
D006350 Heart Valve Prosthesis A device that substitutes for a heart valve. It may be composed of biological material (BIOPROSTHESIS) and/or synthetic material. Prosthesis, Heart Valve,Cardiac Valve Prosthesis,Cardiac Valve Prostheses,Heart Valve Prostheses,Prostheses, Cardiac Valve,Prostheses, Heart Valve,Prosthesis, Cardiac Valve,Valve Prostheses, Cardiac,Valve Prostheses, Heart,Valve Prosthesis, Cardiac,Valve Prosthesis, Heart
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012720 Severity of Illness Index Levels within a diagnostic group which are established by various measurement criteria applied to the seriousness of a patient's disorder. Illness Index Severities,Illness Index Severity
D014261 Tricuspid Valve The valve consisting of three cusps situated between the right atrium and right ventricle of the heart. Tricuspid Valves,Valve, Tricuspid,Valves, Tricuspid
D014262 Tricuspid Valve Insufficiency Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE. Tricuspid Incompetence,Tricuspid Regurgitation,Tricuspid Valve Incompetence,Tricuspid Valve Regurgitation,Incompetence, Tricuspid,Incompetence, Tricuspid Valve,Insufficiency, Tricuspid Valve,Regurgitation, Tricuspid,Regurgitation, Tricuspid Valve,Valve Incompetence, Tricuspid,Valve Insufficiency, Tricuspid,Valve Regurgitation, Tricuspid
D058385 Cardiac Valve Annuloplasty A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annuli of HEART VALVES. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
