T ricuspid regurgitation (TR) is a common finding in patients with left-sided disease, and is associated with poor outcome and predicts poor survival, heart failure, and reduced functional capacity (1). It is common after mitral valve treatment in rheumatic or ischemic mitral regurgitation, if left untreated at the time of mitral surgery. In this subgroup with long-standing TR, managed medicall...
Prenatal Diagnosis and Management of Tricuspid Valve Atresia: A Case Report and Review of Literature
Aim To describe the prenatal features, diagnosis, post-natal follow up and the strategy of treatment of patients suffering from Tricuspid Valve Atresia (TvAtr). Methods We describe a case and its outcome on a three-year follow-up. We review the existing literature on the pre-natal diagnosis, post-natal management and late outcome. Results Based on this case, We present the key findings for diag...
Objective: The present study aims atinvestigating the behavior of realized volatility for high-frequency data of Tehran Stock Index from April28th, 2012 to August 8th, 2018. Methods: Three different types of HAR models including of HAR-RV-CJ, HAR-RV and HAR-RVJ were used to analyze the Realized Volatility. Results: The obtained results of three diverse models revealed that the estimated Reali...
BACKGROUND The outcome of patients with corrected transposition of the great arteries (CTGA) is variably affected by associated intracardiac defects, tricuspid valve competence, and systemic right ventricular (RV) function. The relative importance of these factors in long-term outcome has not been evaluated. METHODS AND RESULTS Since 1958, 40 patients with CTGA were studied to determine risk ...
Abstract Funding Acknowledgements Type of funding sources: None. BACKGROUND. Stress echocardiography (SE) is widely used for the assessment left ventricular (LV) function, diagnostic and prognostic stratification patients with coronary artery disease mitral aortic valve disease. However, right ventricle (RV) in general, particular regard to contractile reserve RV tricuspid (TV) an area that has...
The aim of this study was to investigate the effects of dietary garlic on the growth performance, intestinal mucosa morphology, and pulmonary hypertensive response in broiler chickens with pulmonary hypertension induced by 3, 5, 3′-l triiodothyronine. Chicks were reared for 42 days and treated with triiodothyronine (1.5 mg/kg diet) and 0 (control), 0.2, 0.6 or 1% garlic powder. Intestinal segme...
The bias stress effect in pentacene organic thinfilm transistors has been investigated. The transistors utilize a thin gate dielectric based on an organic self-assembled monolayer and thus can be operated at low voltages. The bias stress-induced threshold voltage shift has been analyzed for different drain-source voltages. By fitting the timedependent threshold voltage shift to a stretched expo...
Abstract Background Anatomic knowledge of the tricuspid valve (TV) is first step in diagnostic algorithm patients with regurgitation (TR), who are candidates for transcatheter intervention (TTVI). Currently, echocardiography and computed tomography (CT) available instruments to study TV anatomy, guide decision-making process support development novel therapies. Purpose The Tricuspid Regurgitati...
