Background: Improvements in ultrasound technology has enabled direct, transthoracic visualization of long portions of coronary arteries : the left anterior descending (LAD), circumflex (Cx) and right coronary artery (RCA). Transthoracic measurements of coronary flow velocity were proved to be highly reproducible and correlated with invasive measurements. While clinical applications of transthoracic echocardiography (TTE) of principal coronary arteries are still very limited they will likely grow. The echocardiographers may therefore be interested to know the ultrasonic views, technique of examination and be aware where to look for coronary arteries and how to optimize the images.
Methods: A step-by-step approach to direct, transthoracic visualization of the LAD, Cx and RCA is presented. The technique of examination is discussed, correlations with basic coronary angiography views and heart anatomy are shown and extensively illustrated with photographs and movie-pictures. Hints concerning optimization of ultrasound images are presented and artifacts of imaging are discussed.
Conclusions: Direct, transthoracic examination of the LAD, Cx and RCA in adults is possible and may become a useful adjunct to other methods of coronary artery examination but studies are needed to establish its role.

Background: Transcatheter aortic valve replacement (TAVR) has significantly advanced the treatment of severe aortic stenosis (AS), particularly in elderly patients who often have coexisting coronary artery disease (CAD). Chronic total occlusion (CTO), a severe form of CAD, may negatively impact outcomes in TAVR patients, though data are limited. This meta-analysis aims to evaluate the impact of CTO on TAVR outcomes.

Background: Acute myocardial infarction during pregnancy is a rare condition with an incidence of 1 to 10 per 100,000 deliveries. ST-elevation myocardial infarction (STEMI) is dominating the clinical presentation. It is estimated that 29% of the patients had normal coronary arteries, and hyperthyroidism may be associated with coronary vasospasm.

This study aimed to examine the employment status of patients who have experienced ischemic heart disease one year after undergoing cardiac rehabilitation. For this, a quasi-experimental pre-post study without a control group of active workers aged 18 to 65 years diagnosed with ischemic heart disease and included in a cardiac rehabilitation programme was conducted. Sociodemographic and occupational data, cardiovascular risk factors and clinical-therapeutic data on heart disease were collected.

The aim of this study is to conduct a comprehensive bibliometric analysis of CT-based adipose tissue imaging related to coronary artery disease (CAD) to investigate the dynamic development of this field. Web of Science Core Collection was used as our data source to identify relevant documents limited to articles or review articles and written in English with no time restrictions. Then we analyzed the whole trend of publications and utilized VOSviewer and Bibliometrix to conduct a bibliometric analysis including citations, keywords, countries, institutions, authors as well as co-citation analyses of cited references and sources.
