Anomalous aortic origin of the right coronary artery from the non-coronary sinus of Valsalva.

We report a rare case of anomalous aortic origin of the right coronary artery from the posterior/non-coronary sinus of Valsalva in a 9-year-old male diagnosed during the workup of premature ventricular contractions. The finding was initially noted on transthoracic echocardiogram and further confirmed with computed tomography. The anomalous coronary artery shows a wide ostium with no intramural or interarterial course.

Stress test to STEMI: Utility of coronary CTA in the diagnosis and management of anomalous right coronary artery from the left coronary cusp.

A 42-year-old woman presented to the emergency department with chest pain. Acute coronary syndrome was ruled out. During dobutamine stress echocardiography (DSE), she developed chest pain and inferior ST elevation. Emergent coronary angiography revealed no culprit lesions but did show an anomalous right coronary artery (RCA). Coronary CT angiography (CCTA) confirmed an anomalous RCA arising from the left coronary cusp with a slit-like ostium and interarterial course (ARCA-LCC-IA). Herein, we review the extant literature on ARCA-LCC-IA, its clinical presentation, the vital role of CTA and MRI in its diagnosis, as well as challenges and controversies surrounding management.

A different kind of Christmas tree: anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA).

Anomalous right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that has an incidence of 0.002%. We report a case of a previously healthy female who presented to our hospital with pneumonia and was incidentally discovered to have ARCAPA. This was initially diagnosed on echocardiography by the unusual echocardiographic finding of multiple color flow Doppler signals around the right ventricular free wall and apex which were subsequently confirmed by angiography to be due to extensive collateral circulation between the left and right coronary arteries. This represents an unusual echocardiographic manifestation of this very rare condition.

A Cardiologist's Clinical Dilemma: An Incidental Finding of a Potentially High-Risk Anomalous Right Coronary Artery Origin.

Coronary artery anomalies may place patients at risk for various adverse events. We present a case of a 62-year-old male with a two-year history of intermittent chest pain. A computed tomography coronary angiogram revealed a rare finding of an anomalous right coronary artery (ARCA) originating from the left ascending aorta, with high-risk features. This case highlights the complexities in diagnosing and managing ARCA, underscoring the importance of individualized care and careful consideration of invasive intervention risks versus potential benefits.

Anomalous Right Coronary Artery Clinical Presentations and Considerations.

Anomalous coronary artery presenting as syncope or acute decompensated heart failure complicated by cardiogenic shock is a relatively rare finding. Here, two unusual presentations are described in which an anomalous right coronary artery (RCA) with interarterial course was found following an initially negative workup. The first case describes a 71-year-old male with known non-ischemic cardiomyopathy presenting with acute decompensated heart failure and cardiogenic shock. The second case highlights a 44-year-old female presenting with intermittent angina and recurrent syncope of unknown etiology. These two cases suggest that the anatomy of coronary arteries and their anatomical variants may play a crucial role in the development of adverse cardiovascular outcomes. Utilizing cardiac computed tomography angiography with a lower threshold in patients presenting with cardiac signs, symptoms, and risk factors would lead to earlier detection of these anatomic anomalies and intervention either medically or surgically for potentially improved long-term outcomes.

Non-selective Aortic Root Angiographic Contrast Injection in a Case of Anomalous Right Coronary Artery Ostium.

Anomalous origin of the right coronary artery (RCA) is a rare congenital cardiovascular anomaly that can pose significant diagnostic challenges during cardiac evaluation. We present a case of a 54-year-old male patient with chest pain and a syncopal episode and subsequently diagnosed with non-ST-elevated myocardial infarction (NSTEMI). Coronary angiography revealed an anomalous origin of the RCA, making it difficult to precisely locate the artery's point of origin with selective contrast injection. During coronary angiography, the use of aortic root non-selective angiographic contrast injection aided in localizing the RCA ostium. Our case highlights the clinical significance of aortic contrast injection as a valuable and safe adjunctive technique in cases of anomalous coronary artery origins. Early detection and precise localization of such anomalies are essential for effective treatment planning and improved patient outcomes. Further studies may help validate the utility of aortic contrast injection in similar cases, thereby enhancing diagnostic accuracy and patient care in the management of anomalous coronary artery ostium.

Anomalous Coronary Arteries: A Cause for Malignant Arrhythmias.

Anomalous aortic origin of a coronary artery (AAOCA) is a congenital condition that can lead to sudden cardiac death (SCD), particularly among young individuals. The cause of SCD is thought to be ischemia, primarily related to the course of the anomalous coronary artery. Surgical intervention, such as unroofing or coronary revascularization, is the preferred management modality for patients with evidence of ischemia or concomitant fixed obstruction. Herein, we presented a case of a 24-year-old male admitted to the emergency department with a history of palpitations, dyspnea, diaphoresis, and syncope. The patient had no prior medical diseases and was eventually diagnosed with an anomalous right coronary artery (ARCA) originating from the left coronary sinus. The patient underwent surgical unroofing of the ARCA to prevent further episodes of ischemia and ventricular arrhythmias. The case highlights that coronary artery anomalies can be life-threatening and lead to SCD, especially in young individuals with no risk factors. Investigating coronary anomalies in medically free patients presenting with cardiac symptoms and arrhythmias is crucial.

Two Cases of Highly Symptomatic Interarterial Anomalous Right Coronary Arteries.

Coronary artery anomalies are a broad group of congenital coronary artery variations. Anomalous aortic origin of a coronary artery is a variant that occurs when a coronary artery arises from an inappropriate sinus of Valsalva. While most patients are asymptomatic, these congenital variants may predispose them to symptoms or even sudden cardiac death (SCD). Unfortunately, no unified consensus exists on risk stratification or management of patients with these congenital variants. We present two unique cases of symptomatic anomalous right coronary arteries and discuss their presentations, imaging findings, and management.

Anomalous Interarterial Right Coronary Artery: Approach to a High-Risk Course.

Congenital coronary anomalies can be an incidental finding in the adult population. Implications of an anomalous coronary artery vary depending on its course and the anomaly. An interarterial course of an anomalous coronary artery is considered malignant with a high risk of sudden cardiac death. The presentation of the interarterial course of an anomalous coronary artery is variable. We report a rare case of an anomalous origin of a right coronary artery presenting with vague symptoms without any evidence of inducible ischemia. Given the rarity of an anomalous interarterial right coronary artery, the implications of this congenital anomaly on physical activity, treatment options including surgical correction, and estimating the risk of sudden cardiac death are difficult based on currently available data.

Surgical management of anomalous origin of coronary artery from pulmonary artery.

BACKGROUND: Anomalous origin of coronary artery from pulmonary artery (AOCAPA), as is evident from the name, is defined as abnormal origin of either coronary artery from the pulmonary artery. The consequences vary in most cases and these anomalies lead to severe coronary hypo-perfusion and ventricular dysfunction. The common variants of this cardiac malformation are an anomalous origin of a left coronary artery from a pulmonary artery (ALCAPA) and anomalous origin of the right coronary artery from a pulmonary artery (ARCAPA). Another rare variant is left main coronary artery atresia that resembles ALCAPA in its mode of presentation. This article presents a single surgeon experience of managing this complex subset of the coronary anomaly from April 2006 to July 2019. MATERIAL AND METHODS: The 105 patients, who underwent surgery for AOCAPA from April 2006 to July 2019, have been included in the study. The patients have been analysed by follow-up echocardiography and electrocardiography (ECG) at our hospital by paediatric cardiologists. Out of 105 patients of AOCAPA, 98 (93.3%) patients underwent ALCAPA repair, of which 59 (60.2%) were males and 39 (39.7%) were females. Four out of five patients, who had an anomalous origin of the left coronary artery from the right pulmonary artery (ALCARPA), had an intramural aortic course. Three patients (3%) had left main coronary artery atresia and four patients (4%) had ARCAPA. It may be mentioned that seven infants (7.14%) and one adult patient (1%) underwent concomitant mitral valve repair. All the patients with ALCAPA, left main coronary artery atresia and ARCAPA, and 1 of the patients with ALCARPA, underwent coronary relocation. In four out of five patients with ALCARPA, unroofing of intra-aortic intramural course was performed. RESULTS: Out of 105 patients of AOCAPA, 9 (8.5%) patients had in-hospital mortality. Five infants (5.0%) with ALCAPA and one patient (1%) with ALCARPA died in the post-operative period due to severe left ventricular dysfunction, mitral regurgitation (MR) and sepsis. One adult patient (1%) with ALCAPA, who underwent coronary relocation using in situ trap door technique and mitral valve (MV) repair, died due to massive intracranial bleeding. Two patients out of three (66.6%) with left main coronary atresia died in intensive care unit (ICU) after 3rd and 4th postoperative day, due to low cardiac output, severe ventricular dysfunction and severe MR. Patients were followed up for a median 5.9 years. Seven patients were lost to follow-up, including the sole survivor of left main coronary atresia, after a median follow-up of 4 years after surgery. Three patients underwent mitral valve replacement for progressive residual MR. There has been no late mortality. CONCLUSION: AOCAPA is a rare congenital cardiac anomaly, which usually presents in infancy with left ventricular dysfunction and mitral valve regurgitation. Early diagnosis and surgical re-establishment of the dual coronary system has given gratifying results, with improvement in left ventricular function in survivors. Mitral valve intervention for MR was required, in both early and late phases.

Anomalous Origin of a Right Coronary Artery from the Pulmonary Artery in a Middle-Aged Woman.

A 53-year-old female patient presented for evaluation of a murmur. The examination revealed a 2/6 systolic ejection murmur in the left upper sternal border. Transthoracic echocardiography with color Doppler showed increased blood flow around the apex of the right ventricle. Further imaging revealed the right coronary artery emerging from the pulmonary artery. (Level of Difficulty: Beginner.).

Valve-sparing root reimplantation in anomalous right coronary origin.

Anomalous origin of coronary artery is a rare anomaly. Performing valve-sparing root reimplantation for aortic root pathology in these patients is challenging. There are modified techniques for performing valve-sparing procedures in this rare subset of patients. Herein, we present a case of anomalous right coronary origin from left ostium managed by conventional valve-sparing root reimplantation.

Anomalous Origin of Right Coronary Artery From Left Sinus of Valsalva.

We present the imaging series of a 52-year-old woman with no cardiovascular risk factors who was admitted for acute coronary syndrome without persistent ST elevation (NSTEMI). Coronary angiography and cardiac computed tomography demonstrated anomalous origination of the coronary artery from the opposite sinus (ACAOS), which is an uncommon coronary anomaly; the incidence is about 1.07% in general, and only 0.12%-0.9% in the case of right ACAOS. The clinical consequences can be relevant if the ectopic artery has intramural intussusception or courses between the aorta and pulmonary artery.

Aorto-left ventricular tunnel with anomalous origin of right coronary artery and bicuspid aortic valve: a case report.

BACKGROUND: Aorto-left ventricular tunnel (ALVT) is a rare congenital extracardiac channel that connects the ascending aorta to the left ventricle. To our knowledge, no case has been thus far reported as ALVT with both anomalous origin of right coronary artery (AORCA) and bicuspid aortic valve (BAV). CASE PRESENTATION: We reported a case of a 5-year-old female diagnosed as ALVT with accompanying AORCA and BAV which had been previously misdiagnosed as aortic regurgitation (AR) triggered by BAV. Additionally, a special modality of ALVT was confirmed in this case during the surgery in which the tunnel was formed by the separation between the roots of two aortic leaflets during the diastolic period. CONCLUSIONS: ALVT with both AORCA and BAV is clinically uncommon and the aberrant tunnel in ALVT can be formed by the gap between the roots of two aortic leaflets. Besides, ALVT with BAV might easily lead to an inaccurate diagnose as aortic regurgitation caused by BAV. Cardiac surgeons should be alerted for differential diagnosis of ALVT with BAV and isolated bicuspid aortic valve (BAV) causing aortic regurgitation (AR).

Intramural Anomalous Right Coronary Artery From the Main Pulmonary Artery.

Anomalous origin of the right coronary artery from the main pulmonary artery (anomalous right coronary artery from pulmonary artery; ARCAPA) is a rare congenital anomaly. Here, we present an unusual case of anomalous right coronary artery from the main pulmonary artery with proximal intramural course.

Anomalous origin of the right coronary artery from the pulmonary artery with aortopulmonary window.

This report describes a rare case of anomalous origin of the right coronary artery from the pulmonary artery associated with a large aortopulmonary window in a 2-month-old boy. The right coronary artery was exposed to systemic pressure and carried fairly well-oxygenated blood to the myocardium. Closure of the aortopulmonary window alone could have caused acute myocardial ischemia. The purpose of this case report is to describe successful diagnosis and management of anomalous origin of the right coronary artery associated with an aortopulmonary window. The pathological findings and the physiological effects, clinical importance, and method of correction used are discussed.
