The clinical diagnosis of the presence and severity of tricuspid insufficiency is difficult and is complicated by the transient nature of this abnormality as well as its usual occurrence in subjects with other valve disease. This paper presents correlative hemodynamic data from 100 consecutive catheterized patients with valvular heart disease in 90 of whom the presence of tricuspid insufficienc...

Valvular endocarditis was diagnosed during a routine flock screen for ovine pulmonary adenocarcinoma (OPA) in 10-month-old ewe lamb with 2-month history of weight loss. Ultrasound examination demonstrated right caudoventral pleuritis presenting as hyperechoic thickening the pleura and irregular lesions measuring approximately 12–15 mm, replacing normal tricuspid mitral valves. The sheep euthana...

T HE PATHOGENESIS of congestive failure is still uncertain. In 1910 Bolton and Starling (I) wrote that the analysis of the factors involved in the production of the disease was rendered difficult by the impossibility of accurately reproducing these states in animals. Since that time numerous methods have been tried to precipitate congestive failure in dogs. The attempts have met with limited su...

In lymphedema, various types of congenital and acquired anomalies opened vessels nodes are observed. They often lead to cardiac hypertension, valvular insufficiency, lymphedema. Today, secondary lymphostasis ranks first among the pathologies system extremities. The etiology this situation, which results in a mechanical disease current lymphatic system, is very different. However, most common ca...

Twenty-four healthy subjects and 33 patients with left-sided valvular heart disease in atrial fibrillation were studied using a pulsed-wave Doppler ultrasound system connected to a 900 two-dimensional echocardiography device. Systolic turbulence in the right atrium (RAST) was studied, and the ratio of maximum systolic velocity to maximum diastolic velocity ratio (MSV:MDV) was determined in the ...
