Coronary Artery Diameter

This study aims to assess the normal coronary diameters of patient who underwent coronary angiogram in Patan Hospital. Angiographic and demographic data of a total of 307 patients (155 males, 152 females; mean age 62.09±11.06 years) who underwent elective coronary angiography in Patan Hospital due to suspicion of coronary artery disease between 2017 and 2020 and in whom coronary angiography documented normal coronary arteries without any intra-luminal irregularity were analyzed retrospectively. Proximal diameters of the main epicardial coronary arteries were measured quantitatively using automated software analysis (Allura, Philips). The mean diameter of unadjusted/adjusted left main coronary artery, proximal left anterior descending artery, proximal left circumflex artery, proximal right coronary artery were 4.87±0.85mm/2.8±0.54, 3.8±0.7/2.19±0.439, 3.4±0.7/1.98±0.44, 3.6±0.85/2.07±0.53 respectively. Our study findings contradict the traditional belief that females have narrower coronary arteries than males. Our study showed the females have statistically significant larger unadjusted Right Coronary Artery diameter and adjusted Left Main Coronary Artery diameter. We believe that our findings may contribute to the global data pool of normal coronary diameters and can be utilized in future studies as a database.

Right Coronary Cusp

Introduction: Anomalous aortic origin of coronary arteries (AAOCA) is uncommon congenital anomalies of the coronary circulation. Anomalous left main coronary artery (LMCA) originating from the right cusp is one of the rarer anomalies (incidence ~ 0.03% of patients undergoing coronary angiography). Mostly asymptomatic, however, this may become clinically significant with symptoms ranging from atypical chest discomfort to sudden cardiac death. We present a case of anomalous origin LMCA from the right coronary cusp. Case presentation: A 47-year-old female presented to the ED with three days of substernal chest pressure at rest. BP 106/71 mmHg, pulse 72 bpm, normal regular heart sounds, and clear lungs. The ECG showed new anterolateral T-wave inversions. Troponin-I was 0.31 ng/ mL. Echocardiogram showed normal LVEF without focal wall motion abnormalities. Coronary angiography revealed a dominant patent RCA without any disease. LMCA originated from the right coronary cusp with focal 90% ostial LAD stenosis. The rest of the coronary tree was free of disease. CABG with LIMA to LAD and SVG to OM1 was performed. Discussion: AAOCA presents a unique challenge to diagnosis and management. CT coronary angiogram or magnetic resonance angiography is recommended for more accurate delineation of the course of the coronary vessel. The diagnostic challenge to effectively engage the anomalous artery and to obtain coronary angiogram to delineate anatomy is critical in further management. As seen in our case, this is easy to overlook and in the acute event could lead to unnecessary delay.

Common Area

Prevalence of anomalous origin of right coronary artery (RCA) from left coronary sinus in population according to autopsy studies is 0.026%. Origin of left main coronary artery and RCA from opposite sinus of Valsalva with further course of anomalous vessels between aorta and pulmonary artery often is linked to sudden death.  We present a case of anomalous origin of RCA from left coronary sinus and aneurysm of aortic root. Our case demonstrates that when both coronary arteries` ostia are close to each other coronary arteries can be re-implanted on common area.  Firstly, this prevents distention and deformation of coronary arteries that might cause myocardial infarction. Secondly, it reduces time of placing anastomosis thus decreasing period of myocardial ischemia and cardiopulmonary bypass time.

We report a case of a malignant course of left main coronary artery in a patient presenting with sudden onset chest pain and shortness of breath. The patient is a 44-year-old African American male with a past medical history of hypertension, diabetes mellitus type 2 as well as dyslipidemia presented to the emergency department with non-exertional chest pain radiating to the left arm and shortness of breath. A coronary angiography and CT angiography (CTA) of heart was performed and it demonstrated an aberrant malignant course of the left main coronary artery coming from the right coronary ostium and coursing between the aorta and pulmonary artery. The left ventricular dysfunction was thought to be a consequence of this malignant course. Cardiothoracic surgery was consulted which determined the need for CABG. The incidence of coronary anomalies and patterns in a series of 1,950 angiograms was determined to be 5.64% with the left main coronary artery (LMCA) arising from the right sinus in 0.15% of the angiograms Diagnostic approach for malignant coronary arteries involves coronary angiography and cardiac CT. A widely accepted treatment approach for left main coronary arteries originating from the right sinus is through surgical repair. Our case urges the clinician to expand the differential diagnosis in young to middle age patient presenting with chest pain. In addition, our case reinforces the concept of the detrimental impact of malignant left coronary arteries on cardiac function. This should prompt the physician to consider coronary anomalies as a possible differential diagnosis as part of the evaluation and management of these patients.

Congenital coronary artery fistula is an extremely rare anomaly that may involve any of the coronary arteries and any of the cardiac chambers. We report the case of a 14-year-old female patient with a symptomatic congenital coronary fistula starting from the left main coronary artery and draining to the coronary sinus. The patient underwent surgical ligation of the fistula and had an excellent outcome.

Abstract Background: With the increased training loads at very early ages in European elite youth soccer, there is an interest to analyse coronary artery remodelling due to high-intensity exercise. Design and methods: Prospective echocardiographic study in 259 adolescent elite male soccer players and 48 matched controls. Results: The mean age was 12.7 ± 0.63 years in soccer players and 12.6 ± 0.7 years in controls (p > 0.05). Soccer players had significant greater indexed left ventricular mass (93 ± 13 g/m2 versus 79 ± 12 g/m2, p = 0.001). Both coronary arteries origin could be identified in every participant. In soccer players, the mean diameter of the left main coronary artery was 3.67 mm (SD ± 0.59) and 2.61 mm (SD ± 0.48) for right main coronary artery. Controls showed smaller mean luminal diameter (left main coronary artery, p = 0.01; right main coronary artery, p = 0.025). In soccer players, a total of 91% (n = 196) and in controls a total of 94% (n = 45) showed left main coronary artery z scores within the normal range: −2.0 to 2.0. In right main coronary artery, a pattern of z score values distribution was comparable (soccer players 94%, n = 202 vs. controls 84%, n = 40). A subgroup of soccer players had supernormal z score values (>2.0 to 2.5) for left main coronary artery (9%, n = 19, p = 0.01) and right main coronary artery (6%, n = 10, p = 0.025), respectively. Conclusion: Elite soccer training in early adolescence may be a stimulus strong enough to develop increased coronary arteries diameters. In soccer players, a coronary artery z score >2.0–2.5 might reflect a physiologic response induced by multiannual high-intensity training.

Abstract Background Takayasu's arteritis (TA) is an inflammatory vascular disease of the young involving the large elastic arteries resulting in occlusive or ectatic changes, mainly in the aorta and its major branches as well as the pulmonary artery and its branches. Materials and Methods The authors reviewed the TA patients admitted over 2 years in their department and who underwent catheterization. They noted the clinical presentations, two-dimensional (2D) echocardiographic features, and angiogram details of all these patients. Results The study population constituted 24 patients with mean age of 28 years. Out of them, 21 (87.5%) were females. Most of the admitted TA patients presented with claudication complaints (79.2%), 37.5% patients had breathlessness, and 12.5% patients had typical stable angina symptoms. Five patients had 2D echo abnormalities, and rest of the patients had normal echocardiogram. Coronary angiogram (CAG) along with aortogram and selective peripheral arteriograms were performed of all these patients. Left main coronary artery (LMCA) disease was seen in three (12.5%) patients. Case details of two (8.3%) patients with multiple anomalous communications of the coronaries with pulmonary vasculature were described. Conclusion TA patients who came for catheterization were predominantly females, mainly involving the aorta and its main branches. In the authors’ TA series of patients, type 5 presentation was there in five (20.8%) patients (three cases of LMCA + two cases of coronary artery to pulmonary parenchymal fistulas). They propose to subclassify type 5 of TA, as they report coronary artery to pulmonary parenchymal fistulas along with the previous literature.
