Coronary occlusion during coronary angiography.
Between January 1, 1970, and December 31, 1974, 2981 patients underwent coronary arteriography. Twelve acute coronary dissections or embolizations occurred, an incidence of 0.4%. The incidences of acute occlusions for the Sones and Judkins techniques were 0.19% (4/2077 studies) and 0.88% (8/940), respectively. No instance of acute occlusion has occurred during the past 490 studies performed by ...
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...
متن کاملEffects of coronary collaterals on regional myocardial function during temporary coronary occlusion and hypoxic coronary perfusion.
The effects of coronary collaterals on regional myocardial function during temporary ischemia and hypoxia were studied in 12 open-chest dogs. Using an ultrasonic dimension gauge, systolic segment shortening in the left anterior descending coronary artery (LAD) area was measured at 1 min after the following three experimental conditions: LAD occlusion and LAD hypoxic perfusion with nonoxygenated...
متن کاملAntiarrhythmic effects of aspirin during nonthrombotic coronary occlusion.
To study the action of aspirin upon the myocardium per se, independent of thrombosis, coronary occlusion with a balloon catheter was induced in 53 anesthetized dogs divided into two groups. One group (N = 20) was treated daily with aspirin (600 mg/dog) for seven days and another (N = 33) was untreated. Left ventricular hemodynamics and precordial ECG mapping were used to assess the influence o...
متن کاملArterial baroreflex impairment in patients during acute coronary occlusion.
OBJECTIVES We tested whether acute coronary occlusion interferes with arterial baroreceptor control of heart rate in humans. BACKGROUND Subnormal baroreflex sensitivity (BRS) is an important risk indicator for sudden death. Animal research indicates that both chronic myocardial infarction and acute coronary occlusion impair baroreflex modulation of heart rate. METHODS We measured RR interva...
