BACKGROUND AND OBJECTIVES Right ventricle (RV) remodeling can determine tricuspid valve (TV) geometry and the severity of functional tricuspid regurgitation (TR). SUBJECTS AND METHODS In 53 patients with various degrees of functional TR and in sinus rhythm, RV and TV geometries were analyzed using real-time 3-dimensional echocardiography, including tenting angles of 3 leaflets, septal-lateral...

The ability to accurately monitor tidal volume (TV) from electrocardiographic (ECG) signals holds significant promise for improving diagnosis treatment across a variety of clinical settings. The objective of this study was to develop a novel method for estimating the TV from ECG signals. In 10 mechanically ventilated swine, we collected intracardiac electrograms from catheters in the coronary s...

BACKGROUND Carcinoid heart disease characteristically affects tricuspid (TV) and pulmonary valves (PV), and TV replacement is helpful in selected patients. There is uncertainty, however, regarding optimal surgical management of PV regurgitation. METHODS AND RESULTS We reviewed 22 patients having operation for carcinoid heart disease and compared those having TV and PV replacement (n=12), to t...

Thirty patients with right ventricular (RV) and 15 with coronary sinus (CS) pacing catheters were studied by M-mode echocardiography. RV catheters, detected in 23, appeared as linear echoes in the right ventricle during mitral valve recordings in 12, adjacent or superimposed on the tricuspid valve (TV) in 14, and immediately anterior to aortic root and pulmonary valve echoes in two with a redun...

to investigate the effects of zataria multiflora boiss essential oil (zmb) on incidence of ascites syndrome and blood parameters of arian broiler chicks, an experiment with 500 one-day-old chicks were conducted. this experiment was based on completely randomized design with 5 treatments including 1) control (basal diet), 2) basal diet with 100 mg/kg probiotic, 3) basal diet with 150 mg/kg avila...

Background The right ventricular infundibular sparing approach (RVIS) to repair tetralogy of Fallot (TOF) avoids a ventricular incision used in the transventricular (TV) approach. Recent data has demonstrated better global right ventricular systolic function in patients who underwent RVIS compared to those who had a TV repair, however the impact of surgical strategy on RV infundibular size and ...
