Single Coronary Artery Anomaly Research Articles

A rare coronary anomaly: the right coronary artery originating from the left anterior descending artery

Coronary artery anomalies are structural variations which are usually detected incidentally as a result of coronary angiographies. Clinically, they are usually asymptomatic. The prevalence of the coronary anomalies was detected to be 1.3% in patients undergoing coronary angiography. Among coronary artery anomalies; the anomaly in which all coronary arteries are originating from a single coronary is called the single coronary artery (SCA). Among the single coronary artery anomalies; the right coronary artery (RCA) originating from the left anterior descending artery (LAD) is an even rarer condition with a rate around 0.009%. In this anomaly, while the RCA usually originates from the left main coronary artery (LMCA), it may also rarely be seen as a branch of the LAD.

Isolated Single Left Coronary Artery Anomalies as An Incidental Finding in ST-Elevation Myocardial Infarction: A Rare Case

Úvod: Solitární koronární tepna (single coronary artery, SCA) bez přidruženého vrozeného srdečního onemocnění představuje vzácnou vrozenou anomálii. Ve většině případů, asymptomatických a zjištěných zcela náhodně, může být SCA příčinou ischemie, městnavého srdečního selhání a náhlé srdeční smrti. Kazuistika: Čtyřiačtyřicetiletá žena byla přivezena na naše oddělení akutních příjmů s typickou bolestí na hrudi. Po vyšetření byla u ní stanovena diagnóza infarktu myokardu zadní stěny s elevací úseku ST. Pacientka následně podstoupila perkutánní koronární intervenci. Selektivní kanylaci pravé koronární tepny (right coronary artery, RCA) nebylo možno provést. Angiografické vyšetření levé koronární tepny prokázalo kritickou stenózu (99%) středního segmentu levé přední sestupné větve (RIA). Byla provedena perkutánní transluminální koronární angioplastika se zavedením stentu do středního segmentu RIA. Dva týdny po intervenci byla provedena tomografická koronární angiografie (coronary computed tomography angiography, CCTA), která potvrdila absenci pravé koronární tepny i stenózu RIA. Závěr: Jednou z nejvzácnějších anomálií je solitární levá koronární tepna při vrozené absenci RCA. U některých pacientů je tato anomálie spojena s rozvojem ischemie; přitom může být život ohrožující. Pro stanovení diagnózy a stratifikaci rizika se přednostně používá metoda CCTA. Přestože si jsme vědomi mezer v našich znalostech o těchto anomáliích, mohou si některé případy vyžádat intervenci, aby se předešlo náhlé srdeční smrti a zvýšila se kvalita života.

A Difficult Route for Percutaneous Coronary Intervention: Single Coronary Artery Anomaly

A Difficult Route for Percutaneous Coronary Intervention: Single Coronary Artery Anomaly

Successful Implantation of Two Stents in the Right Coronary Artery in a Patient with a Single Coronary Artery Anomaly

Single coronary artery is a congenital cardiac anomaly in which the right coronary artery or left main coronary artery originates from a single aortic ostium. Although this coronary anomaly is rare, it has a wide range of clinical manifestations, from being asymptomatic to sudden cardiac death, and the treatment strategies in this anomaly are not clear yet. In this report; we presented single coronary artery originating from the right sinus of valsalva, and successful stenting of the middle and distal right coronary artery in a patient with acute coronary syndrome.

Combined Surgical Treatment of Atherosclerotic Coronary Artery Disease and Moderate Aortic Valve Stenosis in Patient with Concomitant Lipton’s R-III Type of Single Coronary Artery Anomaly

A single coronary artery is a very rare condition, commonly associated with other congenital anomalies. It could be generally considered as neither benign nor malignant form of congenital coronary artery anomalies since its pathophysiological and clinical implications grossly depend on different anatomical patterns defined by the site of origin and distribution of the branches. By presenting the patient who underwent successful coronary artery bypass grafting and aortic valve replacement surgery in a presence of isolated single coronary artery, we intend to emphasize natural and procedural risks and distinguish casual from causal in this extremely rare clinical and surgical scenario.

Although coronary artery anomalies have been accepted as benign conditions, clinical presentations have a large spectrum including chest pain, dyspnea, palpitations, malign arrhythmias, myocardial infarction, syncope and sudden death. An atypical anomalous form of single coronary artery in which the right coronary artery originates from the left anterior descending coronary artery is an extremely rare situaiton. In this report, we presented a case of 63 years old woman who was taken to the coronary angiography due to recurrent chest pain and acute coronary syndrome. Coronary angiography revealed an atypical form of single coronary artery anomaly that the right coronary artery originates from the left anterior descending coronary artery. The treatment strategy was discussed with heart team and patient. Percutaneous coronary intervention (PCI) was performed because of her recurrent chest pain and isolated LAD lesion and preference of the patient. In conclusion, this case is important for demonstrating the feasibility of PCI in patients with single coronary artery anomaly.

A review on single coronary artery

Coronary artery anomalies are rare congenital disorders. They are usually diagnosed incidentally during coronary artery angiogram or post mortem examinations. Single coronary artery (SCA) anomalies are a subset of coronary artery anomalies. The prevalence of single coronary anomalies in the general population is approximately 0.024% according to Lipton’s reports. The various patterns of SCA are difficult to understand. Lipton et al. systematically classified the different types of SCA. Most of the cases of SCA are asymptomatic .The malignant variety of SCA is the type in which the coronary artery courses between the great vessels (Aorta and Pulmonary artery).

Transcatheter coil embolization of a coronary artery-left ventricular fistula associated with single coronary artery anomaly.

Single coronary artery anomaly associated with coronary fistula is a rare entity. Transcatheter coil embolization is the treatment of choice for coronary artery fistulas. In this case report, we describe a patient with both single coronary artery anomaly and coronary fistula who was successfully treated with coil embolization.

Single Coronary Artery Anomaly: Classification and Evaluation Using Multidetector Computed Tomography and Magnetic Resonance Angiography

The aim of this study was to use multidetector computed tomography (MDCT) and magnetic resonance (MRA) angiography to illustrate the classification and clinical characteristics of single coronary artery anomaly (SCAA). Retrospective evaluation of 22 adult and pediatric patients with SCAA by way of a medical archiving system was performed between June 2001 and August 2012. Imaging modalities used for coronary artery evaluation included MRA and MDCT angiography. Of the 22 patients, the majority (n = 8; 36%) showed an interarterial course, the subtype having the worst prognosis. The retroaortic course (n = 3; 14%) and course anterior to the pulmonary trunk (n = 3; 14%) were the next most frequent patterns. Additional types (n = 8; 36%) included the following: L-I, R-III, septal, and combined. Four patients (18%) showed atherosclerotic involvement. SCAA anomaly was diagnosed as an incidental finding in the majority of patients evaluated initially for cardiovascular diseases (n = 19; 86%). Two patients (9%) required surgical interventions solely for their anomaly. Nine patients (41%) were found to have coexisting congenital heart disease. Although conventional catheter angiography is responsible for the current classification of SCAA, advanced imaging modalities are useful in the evaluation of morphological and clinical characteristics of single coronary arteries.

Right coronary artery emerging as a septal branch from the left anterior descending artery

Coronary artery anomalies are detected on approximately 1.3% of coronary angiograms. Single coronary artery anomaly (SCA) is defined as the coronary artery arising from a single coronary ostium, nourishing the entire heart. SCA anomalies are usually benign; however, serious complications such as sudden cardiac death and myocardial infarction resulting from these anomalies are also reported in the literature. We report the anomalous origin of the right coronary artery (RCA) as a continuum of the septal branch from the left anterior descending (LAD) artery, which is a very rare variation of a single coronary artery.

Anomalous Single Coronary Artery on Low Dose MDCT

Coronary artery anomalies may involve the origin, course, and structure of epicardial coronary arteries and occur in less than 1% of the general population. Clinical presentation ranges from being completely asymptomatic to sudden death. Multi-detector computed tomography has come a long way in the diagnosis of coronary artery anomalies since the introduction of 4 rows of detectors in scanners, considering its non invasive nature and the benefits of 3D reconstruction. Defining the coronary anatomy helps in clinical decision making and timely intervention. Since repeated angiographies may be required, low dose CT is an excellent investigation for diagnosis and post interventional follow up rather than repeated invasive catheter angiographies or high dose CT examination. We report two cases of clinically significant single coronary artery anomalies; a case of single Right coronary artery and another case of single Left coronary artery (Anomaly of origin & course).

Coexistence of postpartum cardiomyopathy and single coronary artery anomaly

Postpartum cardiomyopathy (PPCM) is dilated cardiomyopathy seen in the postpartum period in women who no prior history of cardiac diseases. In this case study, coronary angiography was used to determine the etiology of the cardiomyopathy after the decompensated heart failure had regressed. A congenital single coronary artery anomaly was detected by coronary angiography. In this case, PPCM can mimic pneumonia, thus making diagnosis difficult. When there is no response to antibiotic therapy, the obstetrician must consider cardiac disease and appropriate consultation should be obtained as soon as possible. To the best of our knowledge, single coronary artery anomalies coexisting with PPCM has only been documented in one other case in the literature. An association of single coronary artery anomalies with PPCM may be random, or, alternative, might contribute to the composition of the PPCM.

Coronary CTA assessment of coronary anomalies

Coronary anomalies occur in <1% of the general population and can range from a benign incidental finding to the cause of sudden cardiac death. The coronary anomalies are classified here according to the traditional grouping into those of origin and course, intrinsic arterial anatomy, and termination. Classic coronary anomalies of origin and course include those in which a coronary artery originates from the contralateral aortic sinus or the pulmonary artery with anomalous course. Single coronary artery anomalies, in which single coronary artery branches to supply the entire coronary tree, are also included in this category. Anomalies of intrinsic arterial anatomy are a broad class that includes myocardial bridges, coronary ectasia and aneurysms, subendocardial coursing arteries, and coronary artery duplication. Coronary anomalies of termination are those in which a coronary artery terminates in a fistulous connection to a great vessel or cardiac chamber. In the case of those anomalies associated with a risk of sudden cardiac death, the relevant imaging features on CT angiography (CTA) associated with poorer prognosis are reviewed. Recent guidelines and appropriateness criteria favor the use of coronary CTA for the evaluation of coronary anomalies. Although invasive angiography has historically been used to diagnose coronary anomalies, multidetector CT imaging techniques have now become an accurate noninvasive alternative. Cardiac CTA provides excellent spatial and temporal resolution, allowing accurate anatomical assessment of these anomalies.
