چکیده
Case History: A 62-year-old male with a history of hypertension and coronary artery disease with prior stenting to the left circumflex artery presented with chest pain. Echocardiography on admission demonstrated a globally reduced ejection fraction of 10% to 15% with regional wall-motion abnormality consistent with prior anterior and inferolateral infarction. End-diastolic volume of the left ventricle (LV) was 210 mL. Coronary angiography showed evidence of multivessel disease, with 100% occlusion of the left anterior descending coronary artery, 70% in-stent restenosis of the left circumflex artery, and 90% stenosis of the posterior descending artery. To evaluate for the presence of ischemia, the patient underwent a rest-stress myocardial perfusion imaging study, which showed a large area of moderate ischemia throughout the mid left anterior descending coronary artery territory. In addition, there was a small area of scar in the proximal left circumflex artery territory (Figure 1). Clinical discussion ensued as to whether this patient would benefit from bypass surgery or percutaneous revascularization.

The value of myocardial perfusion imaging with Tc-99m MIBI for the prediction of perfusion improvement after percutaneous transluminal coronary angioplasty
Introduction: Percutaneous transluminal coronary angioplasty (PTCA) is an effective method for revascularizing of stenotic coronary vessels. Lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. Introduction of a noninvasive metho...

Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...

Ischemic left ventricular (LV) dysfunction due to coronary artery disease (CAD) is steadily increasing as a consequence of the aging of the population and of improved survival of patients with acute coronary syndromes and currently represents the first cause of heart failure (1). Mechanisms of LV dysfunction in CAD patients are complex and have been elucidated in recent years. A landmark unders...

Chronic heart failure is a major public-health problem with a high prevalence, complex treatment, and high mortality. A careful and comprehensive analysis is needed to provide optimal (and personalized) therapy to heart failure patients. The main 4 non-invasive imaging techniques (echocardiography, magnetic resonance imaging, multi-detector-computed tomography, and nuclear imaging) provide info...
