Transcatheter aortic valve replacement (TAVR) has recently emerged as a therapeutic option for patients with severe aortic stenosis who are considered inoperable.1 To avoid potential complications related to this novel procedure (such as coronary artery obstruction or perivalvular leakage), detailed information on the aortic valve anatomy is critically important.1,2 Multislice computed tomograp...
The electrocardiogram (ECG) remains a crucial tool in the identification and management of acute myocardial infarction (MI). A detailed analysis of patterns of ST-segment elevation may influence decisions regarding the use of reperfusion therapy. The early and accurate identification of the infarct-related artery on the ECG can help predict the amount of myocardium at risk and guide decisions r...
BACKGROUND The number of women veterans is increasing, yet little is known about their cardiovascular risk factors, coronary anatomy, cardiac treatments, and outcomes after cardiac catheterization. Prior studies have shown that nonveteran women have more risk factors, receive less aggressive treatment, and have worse outcomes, despite having less obstructive coronary artery disease than men. Wh...
Coronary artery disease (CAD) is the leading cause of death in the United States and the world. Identifying new risk factors and improving the screening methods for CAD are continuously evolving processes. The coronary artery calcification (CAC) score, as measured by computed tomographic coronary angiography (CTCA) is of intense interest to clinicians and investigators because of its potential ...
Coronary artery anomalies are rare, and their incidence varies from 0.6% to 1.3%. Conventional angiography is a commonly used modality for the assessment of coronary artery anomalies, but it may not identify and define the anatomy of anomalous arteries due to the complexity of the course and three-dimensional orientation of the arteries. We present a rare case of duplicated right coronary arter...
OBJECTIVES This study sought to determine the diagnostic accuracy and impact of the systematic use of coronary echocardiography in a large group of preoperative patients with tetralogy of Fallot (TOF). BACKGROUND Accurate preoperative identification of an anomalous coronary artery crossing the right ventricular outflow tract (RVOT) in patients with TOF is important to prevent coronary injury ...
Coronary artery anomalies are uncommon, with an incidence ranging between 0.2% and 1.4%. Among those least frequently observed is left main coronary artery atresia. We report the case of a 72-year-old man, with asymptomatic severe aortic stenosis and moderate ventricular dysfunction. He underwent preoperative coronary angiography in which it was not possible to examine the left main coronary ar...
Anomalous origin of the right coronary artery: right internal thoracic artery of the right coronary artery bypass is not the answer. Minimally invasive direct coronary artery bypass – a surgical approach for anomalous right coronary artery from left aortic sinus of Valsalva. Anomalous right or left coronary artery from the contralateral coronary sinus: " high-risk " abnormalities in the initial...
BACKGROUND The prevalence of heart failure (HF) is rising in industrialized and developing countries. Though invasive coronary angiography (ICA) remains the gold standard for anatomical assessment of coronary artery disease in HF patients, alternatives are being sought. Computed tomographic coronary angiography (CTA) has emerged as an accurate non-invasive diagnostic tool for coronary artery di...
background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...
