Summary of "Transcatheter innovations in tricuspid regurgitation: Navigate."

Patients with isolated functional or recurrent tricuspid regurgitation are often considered high risk and denied surgery. There has been growing experience for transcatheter tricuspid valve implantation through valve-in-valve or valve-in-ring, and recently, but to a lesser extent, in native annulus. The NaviGate is a novel self-expanding valved-stent designed with unique features to treat tricuspid regurgitation, particularly, in the settings of severely dilated tricuspid annulus. Herein, we present the innovation facets and clinical application of the NaviGate system.

Transcatheter versus medical treatment of symptomatic severe tricuspid regurgitation.

Tricuspid Regurgitation (TR) is associated with increased rates of heart failure (HF) and mortality. Transcatheter tricuspid valve interventions (TTVI) are promising, but the clinical benefit is unkno...

Combined Tricuspid and Mitral Versus Isolated Mitral Valve Repair for Severe Mitral and Tricuspid Regurgitation: An Analysis From the TriValve and TRAMI Registries.

The aim of this study was to retrospectively compare the characteristics, procedural courses, and outcomes of patients presenting with concomitant mitral regurgitation (MR) and tricuspid regurgitation...

Clinical characteristics, diagnosis, and risk stratification of pulmonary hypertension in severe tricuspid regurgitation and implications for transcatheter tricuspid valve repair.

Patients with pulmonary hypertension (PHT) are often excluded from surgical therapies for tricuspid regurgitation (TR). Transcatheter tricuspid valve repair (TTVR) with the MitraClip™ technique is a...

Transcatheter edge-to-edge tricuspid repair for recurrence of valvular regurgitation after left ventricular assist device and tricuspid ring implantation.

Tricuspid regurgitation in patients with left ventricular assist device (LVAD) has a significant impact on prognosis and quality of life, and its effects on liver and renal function could negatively i...

Medical and Biotech [MESH] Definitions

Abnormal protrusion of one or more of the leaflets of TRICUSPID VALVE into the RIGHT ATRIUM during SYSTOLE. This allows the backflow of blood into right atrium leading to TRICUSPID VALVE INSUFFICIENCY; SYSTOLIC MURMURS. Its most common cause is not primary valve abnormality but rather the dilation of the RIGHT VENTRICLE and the tricuspid annulus.

Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.

The pathologic narrowing of the orifice of the TRICUSPID VALVE. This hinders the emptying of RIGHT ATRIUM leading to elevated right atrial pressure and systemic venous congestion. Tricuspid valve stenosis is almost always due to RHEUMATIC FEVER.

Cardiac manifestation of gastrointestinal CARCINOID TUMOR that metastasizes to the liver. Substances secreted by the tumor cells, including SEROTONIN, promote fibrous plaque formation in ENDOCARDIUM and its underlying layers. These deposits cause distortion of the TRICUSPID VALVE and the PULMONARY VALVE eventually leading to STENOSIS and valve regurgitation.

Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE.
