The surgical management of tetralogy of Fallot (TF) may be complicated by anomalies in the course and distribution of coronary arteries. Selective coronary angiography was performed in 119 cases of TF in order to prevent injury of aberrant vessels. In 11 patients, anomalies in the origin of coronary branches were revealed (five patients with a single coronary ostium, five with the anterior desc...

introduction:patients with the coronary slow flow phenomenon (scf) frequently experience angina episodes. the purpose of this study was to determine efficacy of nicorandil in myocardial perfusion in patients with scf. methods: twenty patients (50.85 ± 12.96 y) with scf were studied.  we evaluate coronary slow flow according to protracted thrombolysis in myocardial infarction (timi) frame count....

OBJECTIVE To determine the association between an abnormal ankle brachial index (ABI) and the presence of significant coronary artery disease (CAD) on coronary angiography. STUDY DESIGN Cross-sectional, observational study. PLACE AND DURATION OF STUDY The study was carried out at Sheikh Zayed Hospital, Lahore, from July to October 2007. METHODOLOGY A series of 41 patients undergoing coron...

OBJECTIVES To evaluate the usefulness of the information obtained with SPECT, coronary angio-CT and fusion images, in patients with stable ischemic disease who need invasive coronary angiography (IA). MATERIAL AND METHODS Forty-six patients (65.98±8.3 years) with coronary disease were prospectively included. The fusion images generated after undergoing IA were used to evaluate the performance...

Coronary vessel development is a highly coordinated process during heart formation. Abnormal development and dysfunction of the coronary network are contributory factors in the majority of heart disease. Understanding the molecular mechanisms that regulate coronary vessel formation is crucial for preventing and treating the disease. We report a zebrafish gene-trap vinculin b (vclb) mutant that ...

Congenitally corrected transposition of the great arteries is an unusual cardiac malformation with discordant atrioventricular and ventriculoarterial alignments. Because knowledge of the coronary artery anatomy is a prerequisite for successful repair of this cardiac anomaly, selective coronary arteriography was performed in 13 children (4 male and 9 female; age range 18 months to 16 years) and ...

Coronary artery anomalies (CAAs) occur in 0.64 % to 5.6% of patients undergoing coronary angiography. Most pathophysiology and clinical histories involving CCAs have been fully clarified in the past 30 years. Isolated congenital coronary artery-left ventricle direct microfistulas (CVmF) have been recently described, but the clinical significance and anatomical characteristics associated with th...

INTRODUCTION Recently, the prognostic value of ST segment elevation in lead aVR in acute coronary syndrome (ACS) and its relationship with significant stenosis of the left main coronary artery (LMCAS) and three-vessel disease have been highlighted. AIM Analysis of the relationship between ST segment elevation observed in aVR lead and angiographic severity of coronary artery disease in patient...

Introduction Despite technical progress, coronary magnetic resonance imaging (MRI) still faces multiple challenges including low SNR and small vessel size. Coronary vasodilators, such as sublingual nitroglycerin (NTG) or longer acting nitrates (e.g., isosorbide dinitrate), are commonly used to study coronary circulation. Terashima et al. [1] reported on the impact of sublingual NTG on coronary ...

Coronary heart disease has been one of the main threats to human health. Coronary angiography is taken as the gold standard for the assessment of coronary artery disease. However, sometimes the images are difficult to visually interpret because of the crossing and overlapping of vessels in the angiogram. Also due to the low contrast of the image between the backdrop and the small blood vessels,...
