Single Coronary Artery [PDF]

Texas Heart Institute Journal, 2015
To the Editor: Njeim and colleagues1 reported on a patient in whom the common trunk arising from the right coronary sinus gave rise to all coronary arteries that supplied the myocardium. This anomaly is called single coronary artery. The authors stated that, after the large common trunk, a right coronary artery (RCA) coursed along the ...

Treatment Strategies for Chronic Coronary Heart Disease with Left Ventricular Systolic Dysfunction or Preserved Ejection Fraction—A Systematic Review and Meta-Analysis

Pathophysiology, 2023
In this meta-analysis, we examine the advantages of invasive strategies for patients diagnosed with chronic coronary heart disease (CHD) and preserved left ventricular (LV) function, as well as those with significant LV systolic dysfunction (LV ejection ...

Upregulation of 5-hydroxytryptamine receptor signaling in coronary arteries after organ culture. [PDF]

PLoS ONE, 2014
5-Hydroxytryptamine (5-HT) is a powerful constrictor of coronary arteries and is considered to be involved in the pathophysiological mechanisms of coronary-artery spasm. However, the mechanism of enhancement of coronary-artery constriction to 5-HT during

Localization of coronary bypass targets in hard-to-see coronary arteries

Journal of Cardiothoracic Surgery, 2023
Background Precise identification of coronary arteries and selection of anastomotic sites are critical stages of coronary bypass surgery. Visualization of coronary arteries is occasionally challenging when the heart is covered with a thick layer of fat ...

A Single Coronary Artery Originating from the Right Coronary Sinus with a Typical Course of the Right Coronary Artery and the Interarterial Course of the Left Main, Left Anterior Descending, and Left Circumflex as an Example of a Rare Case of High-Risk Coronary Anomaly

Diagnostics, 2022
In the typical course of the coronary arteries, the right coronary artery comes from the right coronary sinus and descends in the right atrioventricular groove. The left coronary artery trunk begins from the left coronary sinus.

Coronary arterial spasm in single right coronary artery [PDF]

Journal of Zhejiang University SCIENCE B, 2009
We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that

Aneurysmal coronary artery disease of the right coronary artery [PDF]

European Journal of Cardio-Thoracic Surgery, 2003
Coronary artery aneurysms are uncommon, with male dominance and uncertain natural history. The RCA is predilected in 50% of cases. Complications are thrombus, risk of rupture and vasospasm. Treatment is not clearly defined, only anecdotal experience exists. We treated two elder male patients with isolated large aneurysm of the RCA (Fig. 1a,b) presented
