Load dependence of left ventricular diastolic pressure-volume relations during short-term coronary artery occlusion.
We evaluated the effect of altered loading conditions on left ventricular (LV) diastolic pressure-volume relations during acute coronary artery occlusion that was produced by inflation of an intracoronary balloon. Open-chest anesthetized dogs (n = 18) were instrumented so that LV pressure (micromanometer) and LV volume (conductance) could be measured without disturbing the pericardium. The effe...
متن کاملThe electrocardiogram change of conus branch occlusion during right coronary artery angioplasty
There are few reports of electrocardiogram (ECG) changes of conus branch occlusion. A conus branch artery supply to the outflow tract of right ventricle. A conus branch artery is considered as the substrate of Brugada syndrome. We report a case of conus branch occlusion during angioplasty with ST segment elevation in V1-3 like Brugada syndrome ECG. We need to bear in mind that this ECG change m...
متن کاملDiastolic aortic pressure rise during percutaneous transluminal coronary angioplasty: an index of left ventricular systolic dysfunction.
OBJECTIVES To investigate the relation between diastolic aortic pressure response and left ventricular systolic dysfunction during percutaneous transluminal coronary angioplasty. BACKGROUND The abnormal diastolic blood pressure rise during exercise in patients with coronary artery disease probably reflects left ventricular systolic dysfunction rather than the number of stenosed coronary arter...
متن کاملAcute Coronary Artery Occlusion During and After Percutaneous Transluminal Coronary Angioplasty
Background. Acute coronary artery occlusion after percutaneous transluminal coronary angioplasty (PTCA) continues to remain a serious complication despite significant improvement in operator performance and technological advancements. This retrospective study was performed to ascertain the frequency, predictive variables, management, and outcome of acute coronary artery occlusion. Methods and R...
متن کاملRight coronary occlusion during tricuspid band annuloplasty.
CLINICAL SUMMARY A 38-year-old man was referred to the University of Catania for severe mitral regurgitation caused by bacterial endocarditis in a myxomatous mitral valve, with prolapse and chordal rupture of the posterior leaflet. The patient was symptomatic for effort dyspnea. A preoperative echocardiogram showed a dilated left ventricle with 62% ejection fraction. Moderate to severe tricuspi...
