Effects of myocardial contractility on microemboli production by mechanical heart valves in a bovine model

Autor: G, Deklunder, J L, Lecroart, J L, Conger, D, Lapeyre, I, Gregoric, H, Rose, D, Tamez, O H, Frazier

Publikováno v: Texas Heart Institute journal. 27(3)

Microemboli caused by mechanical heart valves have the potential to cause cerebrovascular events. We investigated the effects of myocardial contractility and heart rate on microemboli production in association with conventional and experimental mecha

Transcranial high-intensity Doppler signals in patients with mechanical heart valve prostheses: their relationship with abnormal intracavitary echoes

Autor: G, Deklunder, J L, Lecroart, C, Savoye, B, Coquet, Y, Houdas

Publikováno v: The Journal of heart valve disease. 5(6)

In preceding studies, we reported that abnormal Doppler signals of high intensity (HITS) were frequently found in the cerebral arteries of patients with prosthetic mechanical heart valves. These signals should be attributed either to air microbubbles

Intracardiac hemodynamics in man during short periods of head-down and head-up tilt

Autor: G, Deklunder, J L, Lecroart, E, Chammas, L, Goullard, Y, Houdas

Publikováno v: Aviation, space, and environmental medicine. 64(1)

The intracardiac hemodynamic responses to short periods of 70 degrees head-down and head-up tilts were studied in 12 normal male subjects, ages 19-24 years. Echo-Doppler techniques were used to measure the transmitral and transaortic flow velocities

Cold exposure and ischemic heart disease

Autor: Houdas Y, G. Deklunder, J.-L. Lecroart

Publikováno v: International journal of sports medicine. 13

Exposure to cold causes a vasoconstriction and a tachycardia, both resulting in a rise of blood pressure and cardiac work. This last effect may have a deleterious influence on people suffering from ischaemic heart disease (IHD). Moreover, coronary ar

[Blood flow measurement in arteriovenous fistula. Comparison of 2 ultrasonic methods, direct and indirect by compression of the fistula]

Autor: G, Deklunder, L, Goullard, J L, Lecroart, M, Foulard, Y, Houdas

Publikováno v: Presse medicale (Paris, France : 1983). 19(20)

Measuring blood flow in arteriovenous fistulae in patients under chronic dialysis is of interest to evaluate the repercussions of the fistula on the heart. The apparently simplest method is direct measurement of the mean blood flow velocity by the pu
