Rest and exercise potassium-43 myocardial perfusion imaging for the noninvasive evaluation of aortocoronary bypass surgery.
Sixteen patients undergoing aortocoronary bypass surgery were evaluated with rest and exercise potassium-43 (43K) myocardial imaging and contrast angiography an average of 5.5 months postoperatively. The results of 43K imaging allowed the division of these patients into two groups. Group 1 consisted of patients in whom there was either normalization or significant improvement in postoperative i...
متن کاملCine computed tomographic evaluation of aortocoronary bypass graft patency.
Evaluation of the patency of coronary bypass grafts has previously required hospitalization for invasive angiography. This report of three cases documents the unique capability of cardiac cine computed tomography to easily and accurately define coronary bypass graft patency. In each case, the findings altered therapeutic decisions. This early experience justifies wider application of this techn...
متن کاملNoninvasive assessment of mitral insufficiency by transcutaneous Doppler ultrasound.
Instantaneous aortic arch blood velocity was recorded transcutaneously from the suprasternal notch, using a 2.2 MHz Doppler ultrasound unit, in 18 normals and 16 patients undergoing cardiac catheterization who had murmurs of mitral regurgitation. In normals aortic blood velocity rose rapidly in early systole to a midsystolic peak then fell to zero velocity. These roughly parabolic patterns had ...
متن کاملNoninvasive assessment of atrioventricular pressure half-time by Doppler ultrasound.
The mean pressure drop across the mitral valve and atrioventricular pressure half-time were measured noninvasively by Doppler ultrasound in 40 normal subjects, in 17 patients with mitral regurgitation, 32 patients with mitral stenosis and 12 with combined stenosis and regurgitation. In normal subjects pressure half-times were 20--60 msec, in patients with isolated mitral regurgitation 35--80 ms...
متن کاملEvaluation of renal cortical perfusion by noninvasive power Doppler ultrasound during vascular occlusion and reperfusion.
BACKGROUND Urine output, a frequently used resuscitation end point, is presumed to represent renal cortical perfusion. However, no noninvasive method for direct measurement of renal perfusion exists. Power Doppler ultrasound (PDUS) is a method that reportedly is sensitive to low-velocity and microvascular blood flow and can depict it. This study aimed to develop a quantitative technique for PDU...
