Fro Un an Ca pa R0 Fe su an Ca Sa He oth OBJECTIVES The purpose of this study was to determine whether noninvasive fractional flow reserve derived from computed tomography (FFRCT) predicts coronary revascularization and outcomes and whether its addition improves efficiency of referral to invasive coronary angiography (ICA) after coronary computed tomography

Background: Coronary angiography consists of the selective injection of contrast agents in coronary arteries. Optimal strategy for heparin administration during coronary angiography has yet to be determined. We assessed the effect of heparin administration during coronary angiography on vascular, hemorrhagic, and ischemic complications.Methods: Five hundred candiates for diagnostic coronary ang...

Abstract Background Coronary CT (CCT) is one of the most used noninvasive imaging for detection coronary artery disease (CAD) in US, especially patients with intermediate CAD risk. European Society Cardiology also recommends risk stratifications using angiography suspected (level IB). Purpose purpose study was to evaluate a population that underwent CCT screening, how many had significant lesio...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

Background and Objectives: Studies have shown that patients awaiting coronary angiography (CA) are often anxious. High level of anxiety can lead to physical and psychological stress with adverse effects on organs, es‌pecially heart. There is limited information on state and trait anxiety level in these patients in the literature. This study was thus designed to investigate the level of these tw...

coronary-cameral fistulas (ccfs) constitute a rare anomaly that can be incidentally detected during angiography. ccfs are solitary, large or small assemblies that originate from coronary arteries and enter one of the cardiac chambers. we describe a 29-year-old woman, who referred to our clinic with the chief complaints of palpitation, atypical chest pain, and dyspnea on exertion (functional cla...

Background In patients newly diagnosed with heart failure, coronary angiography is the current gold standard in differentiating underlying coronary artery disease and non-ischemic cardiomyopathy. However, CMR is emerging as an attractive alternative that can provide substantially more diagnostic information with its multiple sequences, while also demonstrating a superior safety profile. In this...

A 23-year-old man was hospitalized with the complaint of exertion dyspnea. Physical examination revealed a third degree diastolic murmur best heard at the left parasternal area. Electrocardiogram showed normal sinus rhythm. Transthoracic echocardiography revealed aneurysmatic dilatation of the left main coronary artery (CA) in addition to the large coronary cameral fistula between the left CA a...
