BACKGROUND: Coronary artery bypass grafting (CABG) is the standard of care for treating left main coronary lesions. However, recently published randomized controlled trials (RCT) have shown conflicting results. We sought to compare clinical outcomes of percutaneous coronary intervention (PCI) with drug-eluting stent placement to CABG using a meta-analysis of randomized controlled trials. METHODS: A systemic search of Pubmed, Scopus, Cochrane library, and Clinicaltrials...

BACKGROUND: Coronary anomalies are rare heart diseases that can cause sudden cardiac death, especially in young individuals. Coronary computed tomography angiography delivers a three-dimensional view of excellent quality with information of the origin, course and anatomic relationships of the anomalous vessel, allowing differentiation between benign and malignant variants, entities that require different management and treatment. AIM: To show that coronary computed tomography angiography is the non-invasive technique of choice for the evaluation of a coronary anomaly due to its high diagnostic accuracy...

BACKGROUND: Kissing-balloon technique (KBT) is commonly performed during percutaneous coronary intervention of distal unprotected left main coronary artery (ULM) aiming at obtaining optimal opening of the side branch (left circumflex artery; LCX) ostium. Nonetheless, detailed evaluation of vascular response to stents in LCX ostium is lacking. We therefore evaluated the vascular response to different drug-eluting stents (DES) in ostial LCX after ULM by means of optical coherence tomography (OCT)...

Obstructive sleep apnea (OSA) results in cardiac dysfunction and vascular endothelium injury. Chronic intermittent hypoxia (CIH), the main characteristic of OSAS, is considered to be mainly responsible for cardiovascular system impairment. This study is aimed to evaluate the role of endothelin-1(ET-1) system in coronary injury and cardiac dysfunction in CIH rats. In our study, Sprague-Dawley rats were exposed to CIH (FiO2 9% for 1.5 min, repeated every 3 min for 8 h/d, 7 days/week for 3 weeks). After 3 weeks, the left ventricular developed pressure (LVDP) and coronary resistance (CR) were measured with the langendorff mode in isolated hearts...

The anomalous origin of the coronary artery from the pulmonary artery (ALCAPA) is the most common congenital coronary artery anomaly. Up to 90% of patients die during the first year of life. It is unusual for an ALCAPA patient to survive to adulthood. We present a case of an asymptomatic young athlete with ALCAPA, in which the diagnosis was established by echocardiography during pre-participation physical evaluation. The patient underwent surgical closure of the left main coronary artery ostium through the inside of the main pulmonary artery and coronary artery bypass grafting...

Coronary artery spasm is a known cause of acute coronary syndrome. However, left main coronary spasm is an extremely rare entity and can present in different ways depending on the duration and severity of the spasm. We present a 44-year-old female patient who presented with transient ST elevation in the lead aVR and ST depression in the lateral and inferior leads. Coronary angiography showed mid left main and ostial right coronary artery spasm that significantly improved after intracoronary nitroglycerine administration...

A 12-year-old boy with intermittent syncope associated with exercise. Exercise stress testing suggested myocardial ischemia and 2D echocardiography failed to confirm antegrade flow in the left main stem. Advanced imaging techniques including cardiac-gated computed tomography angiography and stress cardiac magnetic resonance imaging were falsely reassuring. Cardiac catheterization demonstrated left coronary artery ostial atresia with a good caliber left coronary system supplied by generous collaterals from the right coronary artery...

Importance: Although much less frequent than in adults, coronary artery disease requiring revascularization may develop in children because of homozygous familial hypercholesterolemia or other underlying conditions. Percutaneous coronary intervention (PCI) with a bioresorbable scaffold (BRS) may have advantages over metallic coronary stents in this population. Objective: To present a case of the successful treatment of unstable, multivessel coronary artery disease in a child with PCI with BRS implantation...

Limited data are available on the impact of concomitant left main coronary artery disease (CAD) on mortality after revascularization of multivessel coronary artery disease (MVD) alone or multivessel plus left main coronary artery disease (MVLMD). This study compared long-term mortality between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) with drug-eluting stents in 2,887 patients with MVD or MVLMD. Data were pooled from the BEST, PRECOMBAT, and SYNTAX trials. The primary outcome was death due to any cause...

During percutaneous coronary intervention, stents are placed in narrowings of the arteries to restore normal blood flow. Despite improvements in stent design, deployment techniques and drug-eluting coatings, restenosis and stent thrombosis remain a significant problem. Population stent design based on statistical shape analysis may improve clinical outcomes. Computed tomographic (CT) coronary angiography scans from 211 patients with a zero calcium score, no stenoses and no intermediate artery, were used to create statistical shape models of 446 major coronary artery bifurcations (left main, first diagonal and obtuse marginal and right coronary crux)...

AIMS: Coronary artery aneurysms (CAAs) are incidentally revealed by coronary angiography and consist in a localized dilation of a coronary artery. Although invasive coronary angiography (ICA) is the gold standard imaging technique, it can lead to the underestimation of CAAs diameter in presence of parietal thrombi. Computed tomography coronary angiography (CTCA) is a very sensitive tool in CAAs detection and provides a clear visualization of coronary lumen highlighting intraluminal thrombi...
