Anomalous Origin of Left Circumflex Coronary Artery From Right Pulmonary Artery: An Unusual Cause of Sudden Cardiac Arrest

Anomalous origin of the left circumflex coronary artery from the right pulmonary artery is an extremely rare coronary anomaly out of the group of anomalous coronary arteries arising from the pulmonary artery. We present the case of a 27-year-old male, in whom the diagnosis of an anomalous left circumflex coronary artery from the pulmonary artery was made after sudden cardiac arrest. The diagnosis was confirmed by multimodal imaging and the patient underwent successful surgical correction. Abnormal origins of a coronary artery may become symptomatic later in life and may occur as an isolated cardiac malformation. Due to a potentially unfavorable clinical course, surgical correction should be considered as soon as a diagnosis is made.

CT Detection of an Anomalous Left Circumflex Coronary Artery from Pulmonary Artery (ALXCAPA) in 81-Year-Old Female Patient

The left circumflex coronary artery from the pulmonary artery is a very rare congenital anomaly with few cases described, so far, worldwide. An 81-year-old female presented complaining of dyspnea. The transthoracic echocardiogram revealed severe degenerative aortic stenosis in addition to a hypertrophied left ventricle with normal function and no wall motion abnormalities. As part of the pre-TAVI planning, she underwent a CT examination, which revealed an anomalous left circumflex artery originating from the right pulmonary artery. The case is currently being managed conservatively. The presented congenital coronary anomaly is, to our knowledge, the first to be described in the literature in this age group (80+).

Acute Coronary Artery Occlusion during Transcatheter Aortic Valve Replacement in a Patient with an Anomalous Left Circumflex Coronary Artery

Background Acute coronary artery occlusion (CAO) during transcatheter aortic valve replacement (TAVR) is a rare but life-threatening complication during the procedure; there were a few case reports about an anomalous LCX during perioperative period. We report a case of successful coronary protection using the chimney stenting technique in a patient with a severely calcified aortic valve and an anomalous LCX. Case Summary. A 75-year-old man was found an anomalous left circumflex coronary artery (LCX) originating from the right coronary cusp with severely calcified aortic valve stenosis requiring TAVR. When a self-expanding aortic valve was deployed, we found flow compromise in the right coronary system and circumflex to TIMI-0 flow. By using the chimney stenting technique, we rapidly planted 2 stents from the proximal CX branch to the sinotubular junction and the coronary flow was maintained. Conclusion Chimney stenting protection as a bailout technique is safe and feasible and should be considered in patients deemed to be at high risk of coronary flow compromise, especially with an anomalous LCX.

Successful PCI of Anomalous Left Circumflex Coronary Artery Arising from Right Coronary Sinus – A Case Report

Coronary artery anomalies occur in 1.3-5.6% of patients undergoing coronary arteriography. An anomalous origin of LCX from right coronary sinus is the most common congenital variant. It is usually considered “benign” since it is not known to predispose individuals to sudden cardiac death. Such vessels are particularly predisposed to atherosclerotic disease in their proximal portion, due to the acute angulation of its origin from the aorta and its posterior retro aortic course. We present a case of 55 years old female admitted with acute coronary syndrome. Coronary angiogram showed the anomalous origin of the left circumflex artery from right coronary sinus. This artery had a significant lesion which was successfully stented with a drug-eluting stent.

Australian women's health literacy and complex decision-making to use complementary medicines in pregnancy and lactation – a qualitative investigation

This study reports a case of partial atrioventricular canal defect with an anomalous left circumflex coronary artery in an elderly veteran presenting with unexplained dyspnea on exertion. This is a rare finding in this population and emphasizes the importance of a broad differential diagnosis and meticulous evaluation when more common conditions have been excluded. (Level of Difficulty: Intermediate.)

Successful percutaneous treatment of an anomalous left circumflex coronary artery occlusion after tricuspid valve repair.

The risk of coronary artery injury during valve surgery is higher in case of anomalous coronary artery origin and trajectory. Unlike previous reports on coronary obstruction related to aortic or mitral surgery, we report the first case, to the best of our knowledge, of an anomalous left circumflex artery occlusion after tricuspid valve repair, and its successful percutaneous treatment.

Anomalous origin of circumflex coronary artery from right pulmonary artery associated with atrial septal defect

We describe a 4-year-old girl with anomalous origin of the left circumflex coronary artery from the right pulmonary artery and large atrial septal defect. This is the first reported case of such association. Surgical reimplantation of the anomalous left circumflex coronary artery to the aorta and atrial septal defect surgical closure was performed, with no postoperative complications.

Anomalous Left Circumflex Artery Originating from Right Sinus of Valsalva: A Case Report

Anomalous coronary arteries are known to occur in the general population at a rate of 1-2% however the significance has been the subject of uncertainty throughout the literature. In particular, there is limited data on the clinical significance of an anomalous left circumflex artery originating from the right sinus of valsalva with only a handful of case reports to be found. The aim of this case report is to add to the body of literature indicating that anomalous left circumflex artery originating from the right sinus of valsalva are not all ‘benign’ but in fact can be ‘malignant’ and can result in a patient developing an acute coronary syndrome. Furthermore, this case also adds to the increasing role of computed tomography coronary angiography in the delineation and characterization of coronary anatomy, in particular acute angulation of take off and the slit-like ostium which under exertion may reduce coronary perfusion. We describe a 38 year old male patient who had a non-ST-elevation myocardial infarction after experiencing exertional angina, without evidence of coronary artery disease or inflammatory carditis, and in whom an anomalous left circumflex coronary artery was subsequently.

Complex single ostium coronary artery from the right coronary sinus with unique course of anomalous left circumflex coronary artery

Single ostium coronary artery is a rare coronary artery anomaly. It is reported to occur in only 0.0448% of cases who underwent invasive coronary angiography. It can be associated with angina, arrhythmias, and possibly sudden death and is a clinically important entity to rule out in patients presenting with chest pain. We report the case of a 68-year old man who presented with worsening resting chest pain and underwent invasive coronary angiography and a single ostium coronary artery was identified. Subsequent coronary computed tomography (CT) angiography revealed it to be a unique variation of class R-III of Lipton classification of single ostium coronary artery. Lipton R-III single ostium coronary artery is rare and its incidence is reported to be 0.004% in patients who had invasive coronary angiography. In our case, anomalous left coronary circumflex artery was retroaortic course combined with intramyocardial course. It also divided into multiple obtuse marginal branches in the myocardium and never coursed along the anterior and lateral aspects of the arterioventricular groove. This variation has not been reported in the literature. Coronary CT angiography played an essential role to delineate this complex coronary anomaly.<Learning objective: Single ostium coronary artery is a rare coronary artery anomaly. However, it is a clinically important entity to rule out in the evaluation of patients with chest pain. Invasive coronary angiography can identify this anomaly; however, coronary computed tomography angiography is recommended to fully characterize this condition as demonstrated in our case. Depending on the detailed anatomical information of the anomaly, the clinical management needs to be tailored for these cases.>

Aortic valve/root procedures in patients with an anomalous left circumflex coronary artery and a bicuspid aortic valve: anatomical and technical implications.

An anomalous origin of the left circumflex coronary artery that arises as a side branch of the right coronary artery from the right coronary sinus of Valsalva encircling the aortic annulus is usually an incidental finding. However, in patients undergoing aortic valve procedures, its existence can significantly complicate the surgical treatment. We report our operative strategy in patients with an anomalous left circumflex coronary artery, a bicuspid aortic valve morphology and different aortic valve pathologies.

ST-segment elevation myocardial infarction in a patient with anomalous origin of left circumflex coronary artery

We present a case of ST-segment elevation myocardial infarction in the territory of an anomalous left circumflex coronary artery running through the retroaortic region. In vivo coronary imaging with intravascular ultrasound visualized the usual atherosclerotic change and subsequent plaque rupture and thrombus formation at the culprit lesion. The clarification of pathologic mechanisms underlying the myocardial infarction case could provide information about pathophysiology of atherosclerotic development in anomalous left circumflex coronary artery, and could help in decision-making regarding the management strategy.<Learning objective: Intravascular ultrasound (IVUS) imaging indicated that ordinary atherosclerosis could develop at retroaortic anomalous course of left circumflex coronary artery (LCX) despite absence of mechanical cause of ischemia. IVUS screening could provide significant information about pathophysiology of atherosclerotic development in anomalous LCX, and could help in decision-making regarding the management strategy. The images and discussion have high educational value for clinical cardiologists alike.>

Anomalous dominant left circumflex coronary artery presenting as acute coronary syndrome – STEMI

Among anomalous origin of coronaries, origin of LCX (left circumflex coronary artery) from right sinus is well known. Most of coronary anomalies are silent except a few. Our case is unique in a way that LCX was arising from right sinus & even it was dominant. Above all, it was presented as ACS (acute coronary syndrome). A very few cases among anomalous LCX, are presented as ACS. This case has undergone successful angioplasty (a unique case).
