Coronary artery anomalies are often discovered incidentally during cardiac catheterization or computed tomography coronary angiography and may involve the affected coronary artery origin and its course. Coronary artery anomalies are associated with congenital heart disease. The affected coronary arteries may have an unusual high take off origin, origin from contralateral or non-coronary sinus, origin from the pulmonary artery, single coronary system or coronary artery fistula.

Tetralogy of Fallot correction with transannular patch reconstruction in a patient with an anomalous right coronary artery and an unusual course of the right ventricular branch

Anomalous coronary arteries occur in as many as 12% of patients with tetralogy of Fallot (TOF). In patients with this condition, pulmonary hypoplasia can be prohibitive in performing a valve-sparing repair, subsequently resulting in various techniques to preserve the anomalous coronary artery. The management strategy is often complex in such a situation. We report on a case of TOF with an anomalous right coronary artery crossing the right ventricular outflow tract, with an unusual course of the right ventricular (RV) branch, which precluded placement of a valved conduit. In this case, we performed a successful repair with mobilization of the anomalous coronary artery and reconstruction of the right ventricular outflow tract with a limited transannular patch.

Anatomic variants and anomalies of coronary arteries detected by computed tomography angiography in southern Thailand

Kultida CHY, Ruedeekorn SW, Keerati HS

Med J Malaysia, 2018 06;73(3):131-136.

PMID: 29962495

OBJECTIVE: To evaluate the prevalence of coronary artery anatomic variants and anomalies detected by computed tomography angiography (CTA) MATERIALS AND METHODS: A retrospective study was conducted on all patients undergoing coronary CTA using a 64-detector row CT in the Radiology Department, Songklanagarind Hospital, from January 2010 to January 2013. Data were recorded and analyzed.

RESULTS: The imaging results of 279 patients were reviewed. One hundred and twenty-two females (43.7%) and 157 males (56.3%) [age range, 26-82 years] were reviewed for coronary artery variants and anomalies with post-processing images. The right coronary dominance was the most common dominant type (91.4%). The prevalence of ramus intermedius was 68.8%; those of the absence of the left main coronary artery and left circumflex artery were 0.4%, respectively; and of the high takeoff of the coronary artery was 3.6%. Anomalies of origin and course were detected as the right coronary artery originating from the left coronary sinus in 1.1% of the patients. Myocardial bridging and coronary fistulas were demonstrated in 55.6% and 0.7% of our subjects, respectively.

CONCLUSION: A coronary CTA can effectively represent the complex anatomy of the coronaries as well as their anatomic variations and anomalies. The prevalence of most coronary variations were in concordance with the data of previous reports.

Fulltext Severe left anterior descending artery stenosis with proximal arteriovenous malformation presenting as acute myocardial infarction

Oteh M, Azarisman SM, Hanim NM, Noorfaizan S

Singapore Med J, 2009 Feb;50(2):e76-8.

PMID: 19296018

Congenital coronary artery anomalies are rare, with an incidence of about 0.06-1.3 percent of all patients undergoing cardiac catheterisation. They are commonly asymptomatic, but potentially serious lesions may lead to myocardial ischaemia, infarction and/or sudden cardiac death. The occurrence of a concomitant stenotic lesion is exceedingly rare. We report an 80-year-old man who presented with acute anterior myocardial infarction. Coronary angiography revealed severe proximal left anterior descending (LAD) and arteriovenous malformation (AVM) from the first septal branch of the LAD. The LAD stenosis and the AVM were successfully treated with two Jomed covered stents.

Sudden cardiac death in a young adult man due to spontaneous coronary artery dissection

Subramaniam K, Siew SF, Mahmood MS

Malays J Pathol, 2019 Apr;41(1):51-54.

PMID: 31025638

Spontaneous coronary artery dissection is a rare event and commonly associated with pregnancy and female gender. This condition can reduce or completely obstruct the blood flow to the heart, causing a myocardial ischaemia, abnormalities in heart rhythm or sudden death. We present a case of a 28-year-old Indian male with no previous medical illness who complained sudden onset of chest pain prior to his death. Autopsy revealed a left anterior descending coronary artery dissection associated with plaque rupture. The anterior wall of left ventricle showed contraction band necrosis. There was also atheroma present in the right coronary artery which was insignificant. Histologically, dissection was associated with atherosclerosis. There was no evidence of vasculitis. The cause of death was given as coronary artery dissection due to coronary artery atherosclerosis.

Congenital cyanotic heart disease with situs inversus totalis: an autopsy case report

Dayapala A, Kumar V

Am J Forensic Med Pathol, 2009 Jun;30(2):171-4.

PMID: 19465810 DOI: 10.1097/PAF.0b013e3181875a79

Sudden deaths because of congenital heart diseases are infrequently referred to the forensic pathologist for autopsy. Many of such deaths, if already diagnosed are released directly from the hospital without autopsy. Even forensic pathologists face a few difficulties in performing the autopsy on such infrequent cases, as they are not always updated with the anatomy of anomalies. While dealing with such cases, the concerned forensic pathologist is compelled to refer literature and textbooks again to understand the nature of developmental defects. This is especially so when dealing with cases of situs inversus accompanied by transposition of great arteries and other congenital cardiac abnormalities and variants such as single ventricle, double outlet right ventricle, Taussig-Bing variety etc. In the present case also, situs inversus with transposition of great vessels and other anomalies have been noted and studied.
