coronary artery ectasia

Coronary artery ectasia (CAE), defined as a 1.5-fold or greater enlargement of a coronary artery segment compared to the adjacent normal coronary artery, is frequently associated with atherosclerotic coronary artery disease (CAD). Membrane-bound endothelin converting enzyme-1 (ECE-1) is involved in the maturation process of the most potent vasoconstrictor ET-1. Polymorphisms in the endothelin (ET) gene family have been shown associated with the development of atherosclerosis. This study aims to investigate the effects of rs213045 and rs2038089 polymorphisms in the ECE-1 gene which have been previously shown to be associated with atherosclerosis and hypertension (HT), in CAE patients...

BACKGROUND: Although the implication of receptor of advanced glycation endproducts (RAGE) has been reported in coronary artery disease, its roles in coronary artery ectasia (CAE) have remained undetermined. Furthermore, the effect of RAGE polymorfisms were not well-defined in scope of soluble RAGE (sRAGE) levels. Thus, we aimed to investigate the influence of the functional polymorphisms of RAGE -374T > A (rs1800624) and G82S (rs2070600) in CAE development. METHODS: This prospective observational study was conducted in 2 groups selected of 2452 patients who underwent elective coronary angiography (CAG) for evaluation after positive noninvasive heart tests...

Coronary artery ectasia (CAE) is characterized by the abnormal dilation of coronary arteries, resulting in disturbed or slow blood flow, which causes angina pectoris-the most prevalent symptom of CAE. To date, there is no consensus on the therapeutic management of CAE due to its rarity and the scarcity of research. We present a case series of five patients with different ethnicities, including both men and women, whose CAE was successfully managed by the administration of ranolazine. All five patients were found to have CAE by coronary angiography, which was also associated with slow blood flow...

A coronary artery aneurysm (CAA) is defined as the dilatation of a vessel with a diameter of ≥1.5 times that of the adjacent normal vessel. Occasionally, aneurysms can be large enough to be characterized as giant CAAs, but there is no universally accepted definition. We discuss the case of a 45-year-old male patient who presented to the hospital with substernal chest pain. His ECG revealed ST depression and T wave inversions in precordial leads. Cardiac biomarkers were within normal limits. Due to concerns about coronary artery disease, cardiac catheterization was done, which revealed CAAs in the distribution of the right coronary artery (RCA), left anterior descending (LAD) and left circumflex (LCX) artery...

AIMS: Coronary artery ectasia (CAE) has been linked to the occurrence of adverse events in patients with ischemia/angina and no obstructive coronary arteries (INOCA/ANOCA), while the relationship between CAE and myocardial infarction with nonobstructive coronary arteries (MINOCA) has been poorly investigated. In our study we aimed at assessing differences in clinical, angiographic and prognostic features among patients with CAE and MINOCA vs. INOCA/ANOCA presentation. METHODS: Patients with angiographic evidence of CAE were enrolled at the University Hospital of Parma and divided into MINOCA vs...

Coronary artery ectasia (CAE) is defined as abnormal dilation of a coronary artery with a diameter exceeding that of adjacent normal arterial segment by >1.5 times. CAE is a pathological entity of the coronary arteries and characterized as a variant of coronary atherosclerosis. CAE frequently coexists with coronary artery disease (CAD). While inflammation appears to be involved, the pathophysiology of CAE remains unclear. Damage-associated molecular patterns (DAMPs), defined as endogenous molecules released from stressed or damaged tissue, are deemed as alarm signals by the innate immune system...

OBJECTIVE: Earthquakes can significantly impact both the occurrence and the management of acute coronary syndromes (ACS). This study aimed to investigate the effects of an earthquake on patients with ACS by comparing their clinical and angiographic features before and after the event. METHODS: We utilized a retrospective observational cohort design, involving 260 ACS patients who underwent coronary angiography. Data on patient characteristics, clinical variables, and procedural details were extracted from medical records...

PURPOSE OF REVIEW: Coronary artery fistulas (CAFs) are rare coronary anomalies that most often occur as congenital malformations in children. Although most children with CAFs are asymptomatic at the time of diagnosis, some present with symptoms of congestive heart failure in the setting of large left-to-right shunts. Others may develop additional complications including coronary artery ectasia and coronary thrombosis. Surgical and transcatheter closure techniques have been previously described...

There was an 83-year-old man having coronary artery disease associated with coronary artery ectasia who occurred ventricular fibrillation suddenly during coronary artery angiography. As Kawasaki disease was suspected to the most likely reason which led to coronary artery lesion.

In an adult patient, coronary artery fistula involving the circumflex artery (CX) connected to the coronary sinus caused aneurysm of the left main and CX associated with ectasia of the intermediate branch. The patient had posterolateral infarction with severe ischemic mitral regurgitation and moderate tricuspid regurgitation. A rare venous return anomaly was also present. The inferior vena cava, which was interrupted at the level of the liver, continued with the hemiazygos to drain into a persistent left superior vena cava, which in turn drained into the coronary sinus...

The Ross-Personalized External Aortic Root Support procedure is a surgical aortic valve replacement technique in which the autologous pulmonary valve is transposed in the aortic position to replace the malfunctioning aortic valve and a homograft is implanted in the pulmonary position. To prevent autograft dilatation, a Personalized External Aortic Root Support prosthesis is included in the proximal autograft anastomosis and wrapped around the ascending aorta. The aorta is transected transversely, the aortic valve is resected, and the coronary arteries are mobilized and cut out of the sinuses, leaving a rim...

BACKGROUND: Population-wide, paraganglioma (PGL) is uncommon. The incidence of Takotsubo syndrome (TTS) ranges from 0.5% to 0.9% and also is an exceedingly rare manifestation of PGL. Coronary artery ectasia (CAE) is also uncommon, with an incidence ranging from 1.2% to 4.9%. Herein, we present a case of PGL, TTS, and Markis type I CAE that occured in the same patient. CASE PRESENTATION: A man in his early 40s was admitted to our hospital with a 16-hour history of abdominal colic...

We present a case of recurrent myocardial infarction with coronary artery ectasia that had progressive dilation. Both implanting drug-eluting stent and antithrombotic therapy with warfarin plus P2Y12 inhibitor were feasible. The careful follow-up including morphologic evaluation may be needed for this specific lesion. ( Level of Difficulty: Intermediate. ).
