The patient, a 69-year-old woman, had been diagnosed with a heart murmur. A chest X-ray at a local clinic had shown an abnormal shadow. Since CT revealed a 3-cm-diameter mass close to the pulmonary artery, we performed a coronary angiography and diagnosed her as having a coronary artery aneurysm associated with a coronary-pulmonary artery fistula. We incised the aneurysm under cardiac arrest, t...
background: practice of interventional cardiology procedures such as coronary angiography (ca) and percutaneous transluminal coronary angioplasty (ptca) has largely increased in recent years and is now changing to a matter of routine in many hospitals. the purpose of this study was to measure skin and organ doses in patients undergoing ca and ptca and to find a probable relation with cardiologi...
transcatheteraortic valve implantation, first introduced in 2002, has been established as an alternative modality for patients deemed not suitable for open-heart surgery. the anatomical vicinity of the atrioventricular node and the his bundle to the non-coronary and rightcoronary aortic cusps predisposes patients to conduction abnormalities in case of severe calcification or mechanical trauma d...
Coronary angiography, cine left ventriculography, and the cardiovascular hemodynamics of 24 patients with left bundle branch block were studied. Seven patients were found to have significant coronary artery disease, always severe. Five had cardiomyopathy and seven had valvular disease. Only those with coronary artery disease or cardiomyopathy had abnormal left ventricular contraction patterns. ...
BACKGROUND The location of acute myocardial infarction (MI) is an important prognostic factor for risk stratification of patients with first ST-segment elevation MI (STEMI). The main goal of this study was to compare the severity and extension of coronary involvement in inferior and anterior MI. METHODS This study reviewed angiographic reports of 579 patients with a first anterior wall STEMI ...
A 68-year-old male with a history of hypertension and hypercholesterolemia presented with recurrent episodes of chest discomfort. A 12-lead ECG and an echocardiogram were normal. A myocardial perfusion study could not rule out ischemia in the inferior wall. At coronary angiography using the transradial approach, the right coronary artery (RCA) could not be visualized. Angiography of the left co...
Coronary heart disease (CAD) is the leading cause of death specially among elderly. Coronary angiography is the best diagnostic method in the patients, but is unfortunately an invasive procedure with its inherent risks. Myocardial perfusion scan is a noninvasive and sensitive method for evaluation of CAD and is suggested by many investigators in recent years. In this study, 64 patients wh...
A 58-year-old man was admitted with a 6-week history of fever, lethargy, arthralgia, and dyspnea on exertion. He had no prior illness or cardiovascular risk factors, and with the exception of a pyrexia, his physical examination was unremarkable. Investigations were performed, including blood and urine cultures and a connective tissue screen. He was subsequently discharged with a view to an earl...
background coronary artery disease is the single most important cause of mortality and morbidity in diabetic patients. electrocardiographic stress test is a non-invasive modality to screen significant coronary involvement in minimally symptomatic diabetics. objectives we investigated the positive predictive value (ppv) of this test in comparison with coronary angiography. materials and methods ...
DESCRIPTION A 71-year-old man was admitted with a 2-day history of intermittent palpitations. His initial ECG demonstrated a supraventricular tachycardia with a heart rate of 170 bpm. Following treatment with verapamil he reverted to sinus rhythm. As part of his initial investigations he had a two dimensional transthoracic echocardiogram. The parasternal long axis view demonstrated a well-circu...
