Lower than expected elevated tricuspid regurgitant jet velocity in adults with sickle cell disease in Nigeria.

Summary of "Lower than expected elevated tricuspid regurgitant jet velocity in adults with sickle cell disease in Nigeria."

Cardiopulmonary disease is a major cause of morbidity and mortality in persons with sickle cell disease (SCD). Tricuspid regurgitant jet velocity (TRJV) and predicted forced expiratory volume in 1 s (FEV1%) predicted are independently associated with death in SCD. The goal of this study was to determine the prevalence of elevated TRJV and the association, if any, between TRJV and FEV1% predicted among persons with sickle cell anaemia (SCA) in Nigeria.

Reference Ranges and Determinants of Tricuspid Regurgitation Velocity in Healthy Adults Assessed by Two-Dimensional Doppler-Echocardiography.

Tricuspid regurgitation velocity (TRV) is the most widely used parameter by transthoracic echocardiography (TTE) in the evaluation of patients with suspected pulmonary hypertension (PH).

Impact of right ventricular dysfunction and end-diastolic pulmonary artery pressure estimated from analysis of tricuspid regurgitant velocity spectrum in patients with preserved ejection fraction.

We aimed to analyse the association between right haemodynamic parameters, right ventricular (RV) dysfunction parameters, and outcomes in patients with preserved ejection fraction (EF).

First-in-man implantation of the Tricento® transcatheter heart valve for the treatment of severe tricuspid regurgitation.

Here we describe the first implantation of the novel bicavally anchored Tricento® transcatheter heart valve via transvenous transfemoral access in a 74-year-old woman with severe tricuspid regurgitat...

Lower limb angular velocity during walking at various speeds.

Although it is well established that lower limb joint angles adapt to walking at various speeds, limited research has examined the modifications in joint angular velocity. There is currently no normat...

Physical Activity and Cognitive Function Among Older Adults with an Elevated Gamma Gap.

We evaluated whether gamma gap is associated with cognitive function among older adults and whether physical activity is favorably associated with cognition among those with an elevated gamma gap. Ma...

Medical and Biotech [MESH] Definitions

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.

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.

Heart murmurs which are systolic in timing. They occur between the first and the second HEART SOUNDS, between the closure of MITRAL VALVE and TRICUSPID VALVE and the closure of semilunar aortic and pulmonary valves. Systolic murmurs include ejection murmurs and regurgitant murmurs.

Measurement of the index of refraction (the ratio of the velocity of light or other radiation in the first of two media to its velocity in the second as it passes from one into the other).

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