OBJECTIVES Our study objective was to determine whether the presence of steal-prone anatomy conferred an increased risk in the development of intraoperative myocardial ischemia. BACKGROUND Coronary artery steal of collateral blood flow has been demonstrated for many vasodilators, including isoflurane, the most commonly used inhalational anesthetic agent in the United States. It has been postu...

Coronary bifurcation is defined by the European Bifurcation Consensus as a coronary artery stenosis adjacent to origin of significant side branch. Its anatomy composed 3 different segments: proximal main vessel, distal vessel and lesions are encountered in approximately 15–20% all percutaneous interventions constitute complex subgroup characterized lower procedural success rates higher adverse ...

We read with great interest a report by Gallo et al. [1] on a very rare coronary artery anatomy. In a classification of single coronary artery (SCA) by Lipton et al. [2] with modifications by Yamanaka and Hobbs [3], this case refers to the R-IIIC type of SCA. Indeed, there is little discrepancy between terminology and anatomy in this type of SCA, which is very apparent in the present case. Acco...

BACKGROUND A normal anatomy of coronary arteries is important to have adequate cardiac muscle blood supply especially during extraneous physical activities. This case report describes a rare coronary anomaly in which the accessory coronary artery arose from the right coronary artery, reentered the left anterior descending coronary artery, and then ran as a single vessel. CASE PRESENTATION We ...

OBJECTIVE In this part one of a two-part article, we aim to illustrate our understanding of and approach to comprehensive cardiac CT reporting, cardiac CT technique, and coronary calcium scoring CT, as well as normal and anomalous coronary artery anatomy. CONCLUSION Structured cardiac CT reporting is important to effectively communicate with referring clinicians. Knowledge of cardiac CT techn...

BACKGROUND A previous study has shown an increased prevalence of late gadolinium enhancement cardiovascular magnetic resonance (LGE CMR) detected unrecognized myocardial infarction (UMI) with increasing extent and severity of coronary artery disease. However, the coronary artery disease was evaluated on a patient level assuming normal coronary anatomy. Therefore, the aims of the present study w...

we report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. we present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery – the theories and treatments are discussed. a 85 year-old female was admitted under the care of the  cardiothoracic team with signs ...

introduction: the aim of this study was to evaluate the impact of measurement of coronary artery calcification score (cac) in patients with suspected coronary artery disease (cad) and a normal myocardial perfusion scan. methods: in a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of cad and a normal perfusion scan. in ...
