BACKGROUND: Trans-radial coronary intervention is a popular technique due to patient comfort and lower complication rate. The main complications of this method are artery spasm, vessel perforation, and formation of pseudo-aneurysm. CASE REPORT: In this report, an unusual complication of radial access angiography was encountered. Shortly after the procedure, the patient's right arm began to swell and a pulsating mass grew over the medial aspect of the arm. Right brachial artery angiography was performed immediately for rolling out brachial artery perforation...

Coronary angiography has been the principle modality for assessing the severity of atherosclerotic coronary artery disease for several decades. However, there is a complex relationship between angiographic coronary stenosis and the presence or absence of myocardial ischemia. Recent technological advances now allow for the assessment of coronary physiology in the catheterization laboratory at the time of diagnostic coronary angiography. Early studies focused on coronary flow reserve (CFR) but more recent work has demonstrated the physiologic accuracy and prognostic value of the fractional flow reserve (FFR) and instantaneous wave free ratio (iFR) for the assessment of coronary artery disease...

Cardiovascular disease continues to be the leading cause of death among women in the United States. One of the barriers to improving cardiovascular disease outcomes in women is the lack of reliable, effective screening modalities. Breast arterial calcification has emerged as a potential risk stratification tool. Localized deposition in the media of the artery, known as Mönckeberg medial calcific sclerosis, is notably different from the intimal atherosclerotic process commonly associated with coronary artery disease...

BACKGROUND: Ageing is a risk factor for both coronary artery disease (CAD) and reduced renal function (RRF), and it is also associated with poor prognosis in patients with CAD or RRF. However, little is known about whether the impact of RRF on clinical outcomes are different in CAD patients at different age groups. This study aimed to investigate whether ageing influences the effect of RRF on long-term risk of death in patients with CAD. METHODS: A retrospective analysis was conducted using data from a single-center cohort study...

Computed tomographic (CT) coronary calcium scoring has been established by large prospective, population-based studies as the single best noninvasive predictor of atherosclerotic cardiovascular risk available today. The calcium score correlates highly with the total burden of coronary atherosclerosis demonstrated at autopsy. It adds significantly to traditional risk calculators such as the Framingham Risk Calculator or the Pooled Cohort Equations. The 2018 U.S. Cholesterol Guidelines endorse the use of CT coronary calcium scoring to refine risk estimates in the intermediate range of 7...

A 73-year-old male was referred to our hospital for acute congestive heart failure. His cardiac and respiratory conditions were worsening with cardiogenic shock requiring intubation. Coronary angiography revealed severe triple vessel disease, and echocardiography showed severe left ventricular dysfunction. Therefore, he underwent veno artery extracorporeal membrane oxygenation (VA-ECMO) followed by percutaneous left ventricular assist device (Impella). His cardiac condition improved and VA-ECMO and Impella were removed on the 2nd day and the 4th day after surgery, respectively...
