Improvement of tricuspid regurgitation after pulmonary thromboendarterectomy

2002

For patients with chronic thromboembolic pulmonary hypertension who undergo pulmonary thromboendarterectomy (PTE) it has not yet been systematically investigated how operation affects the severity of tricuspid regurgitation (TR). This study sought (1) to evaluate the extent of TR reversibility after operation, (2) to identify potential predictors of the reversibility of TR, and (3) to investigate the influence of geometric and hemodynamic alterations on the extent of TR severity.Thirty-nine patients (55+/-12 years) undergoing PTE without tricuspid valve repair were investigated before and 13+/-8 days after operation by Doppler color flow mapping. Geometry of the tricuspid valve as well as r…

Intraoperative Evaluation of Reconstruction of the Atrio ventricular Valves by Transesophageal Echocardiography

1987

In a total of 30 operations the mitral valve was reconstructed in 18, the tricuspid valve in 11, and both AV-valves in one patient. The result of reconstruction was tested first in the open arrested heart by injection of crystalloid solution into the appropriate ventricle either through the reconstructed valve or one of the great arteries. Upon termination of cardiopulmonary bypass the valve function was examined in the beating heart by means of transesophageal contrast echocardiography (TEE). For visualization 0.5-1.0 cc of agitated Gelifundol was injected into the ventricle. In 22 patients open testing as well as echocardiographic visualization showed identical and good operative results.…

Assessment of the Tricuspid Valve Morphology by Transthoracic Real-Time-3D-Echocardiography

2005

Aim: To demonstrate the feasibility of transthoracic three-dimensional real-time echocardiography (3D-TTE) supplemental to routine assessments of the tricuspid valve and to analyze interrater agreement. Methods: Twenty healthy subjects and 74 patients with right ventricular failure were examined with conventional 2D and additionally 3D-TTE (SONOS 7500, Philips, Netherlands). The 3D exams were performed and recorded by one of two raters. The recordings were evaluated offline and independently by both raters for visualization of morphological and functional features of the tricuspid valve according to a subjective 3-point scale. Statistical analyses were performed for interrater agreement and…

Heart Valve Abnormalities in Systemic Sclerosis Patients; A Multicenter Cohort Study and Review of the Literature

2020

Background Systemic sclerosis (SSc) is a chronic autoimmune disease that is characterized by vasculopathy and fibrosis of the skin and visceral organs. Heart valve diseases are poorly described and generally not considered typical of SSc. We aimed to describe valvular abnormalities in a multicenter cohort of SSc patients and to investigate their correlation with SSc features. Methods We recruited 118 consecutive SSc patients (male/female, 14/104; mean age, 55.2 ± 12.1 years) in 3 rheumatology centers in Sicily, Italy, from January to October 2019. Results Mitral and tricuspid valve insufficiency was found in 85% and 91% of patients, respectively; regurgitations were generally mild and never…

Computed tomography imaging needs for novel transcatheter tricuspid valve repair and replacement therapies

2020

Abstract Transcatheter tricuspid valve therapies are an emerging field in structural heart interventions due to the rising number of patients with severe tricuspid regurgitation and the high risk for surgical treatment. Computed tomography (CT) allows exact measurements of the annular plane, evaluation of adjacent structures, assessment of the access route, and can also be used to identify optimal fluoroscopic projection planes to enhance periprocedural imaging. This review provides an overview of current transcatheter tricuspid valve repair and replacement therapies and to what extent CT can support these interventions.

Tricuspid valve repair with the Cardioband system: two-year outcomes of the multicentre, prospective TRI-REPAIR study

2021

AIMS: Tricuspid regurgitation (TR) is associated with high morbidity and mortality rates with limited treatment options. We report one- and two-year outcomes of the Cardioband tricuspid valve reconstruction system in the treatment of ≥moderate functional TR in the TRI-REPAIR study. METHODS AND RESULTS: Thirty patients were enrolled in this single-arm, multicentre, prospective study. Patients were evaluated as having ≥moderate, symptomatic functional TR and deemed inoperable due to unacceptable surgical risk. Clinical, functional, and echocardiographic data were prospectively collected up to two years (mean duration 604±227 days). At baseline, 83% were in NYHA Class III-IV, and the mean LVEF…

Update on tricuspid regurgitation

2014

Although commonly detected by transthoracic echocardiography, tricuspid regurgitation (TR) has been somehow neglected, and recent data have emerged on the need for careful examination of the tricuspid valve. Functional or secondary TR is the most frequent etiology of tricuspid valve pathology in western countries and is related to tricuspid annular dilation and leaflet tethering. The prognostic role of TR associated with organic left-sided valvular heart disease is well known. However, the value of functional TR in outcome stratification of patients with advanced left ventricular dysfunction is less clear. Surgical tricuspid repair has been avoided for years, because of the misconception th…

Impact of Prosthesis-Patient Mismatch after Mitral Valve Replacement

2016

Background and aim of the study: The study aim was to determine the impact of prosthesis-patient mismatch (PPM) on early and late clinical outcomes, left atrial and ventricular remodeling, late tricuspid valve regurgitation and pulmonary hypertension (PH) in patients after mitral valve replacement (MVR). Methods: A total of 46 patients (mean age 66 ± 9.3 years) with mitral valve diseases and undergoing isolated MVR was enrolled in the study. The mitral valve effective orifice area (EOA) was determined using the continuity equation and indexed for the patient’s body surface area (EOAi). PPM was defined as EOAi ≤1.2 cm2/m2. PH was defined as a systolic pulmonary artery pressure (sPAP) >40 mmH…
