Pulmonary valve echo motion in pulmonary regurgitation.
Four cases are presented to illustrate the echo patterns of pulmonary valve motion in patients with pulmonary regurgitation caused by pulmonary hypertension, idiopathic dilatation of the pulmonary artery, or congenital absence of the pulmonary valve or in association with pulmonary stenosis. Absence of the pulmonary 'a' wave, fluttering of the e-f slope, and midsystolic closure or 'notching' of...
متن کاملEchocardiographic findings in athletic horses with pulmonary regurgitation
BACKGROUND: Determining the clinical significance of cardiac murmurs is widely considered in equine practice. Pulmonary murmurs are commonly detected in athletic horses. Echocardiography plays a leading role in assessment of these murmurs. OBJECTIVES: Echocardiographic evaluation of horses with pulmonary regurgitation and determining the importance of pulmonary valve murmurs. METHODS: A total n...
متن کاملNorepinephrine induced pulmonary congestion in patients with aortic valve regurgitation.
The regulation of venous blood flow into the heart and the effects of blood volume redistribution upon cardiac function have not been amply defined. While enhanced venomotor tone induced by norepinephrine has been found to increase the volume of a central reservoir in the dog (1), such a volume shift has not been demonstrated in man, except inferentially by the finding of a decrease in the limb...
متن کاملAn efficient way to make a trileaflet conduit for pulmonary valve replacement.
Pulmonary regurgitation after repair of tetralogy of Fallot has always been an important issue for pediatric cardiac surgeons. Some of the patients may need pulmonary valve replacement in the future. Conventional prosthesis valves were seldom custom made for the pulmonary valve and were often inadequate to use because of variable age and size of these patients. Through evolution of techniques, ...
متن کاملElectrospun bioresorbable trileaflet heart valve prosthesis for tissue engineering: in vitro functional assessment of a pulmonary cardiac valve design.
SUMMARY Currently implanted prosthetic heart valves, both mechanical or biological ones, are used to restore the proper blood hemodynamics when the native valves fail. However, these medical devices are not free from drawbacks, such as hemolysis or calcification, also presenting the relevant disadvantage of being unable to growth, repair and remodel. An improvement could be represented by biore...
