“…In the literature, 86%-87% of the general population show right coronary dominance, while 9%-9.5% show left dominance, and 3%-4% show co-dominance (15,16). Results from our dual LAD series are in accordance with the general population in terms of coronary dominance (89% right-dominance and 11% left dominance), ex- cept for the absence of codominance in this study.…”

ORIGINAL ARTICLE PURPOSEWe aimed to evaluate the frequency and features of dual left anterior descending artery (LAD) variants using computed tomography (CT) angiography. METHODSA total of 1337 consecutive coronary CT angiography examinations performed between April 2010 and December 2013 were retrospectively evaluated for the presence of dual LAD. CT examinations were performed with either 64-or 320-row multidetector CT scanners. All CT angiography images were evaluated for the presence and morphologic features of dual LAD subtypes. RESULTSFifty-six dual LAD variations (4%) were identified in this study population. Type 1 was the most common type of dual LAD (n=48), while Type 3 (n=3) and Type 4 (n=2) were infrequent and Type 2 was not detected. Additionally, we detected previously unclassified dual LAD variations in three cases. CONCLUSIONDual LAD may be a relatively more common variant than described in the medical literature, which is mostly based on catheter angiography studies. Coronary CT angiography seems markedly efficacious for detecting and documenting the anatomical details of dual LAD subtypes, as well as showing other associated cardiocoronary anomalies. Dual left anterior descending (LAD) coronary artery is a rare congenital anomaly (1), basically defined as the existence of two distinct segments of the vessel occupying the anterior interventricular sulcus (AIS) of the heart.First study classifying dual LAD anomalies based on coronary catheter angiography was published in 1983 by Spindola-Franco et al. (2), which has served as a primary classification system. However, individual reports further described previously unclassified LAD variants (3, 4). Most of the recent publications about dual LAD anomalies involve case reports and there is a paucity of large series using coronary computed tomography (CT) angiography (3-8).At present, quite a large number of coronary CT angiography examinations are being performed and recognition of dual LAD variations by CT angiography requires familiarity. Being aware of dual LAD anomalies could be critical for coronary bypass surgery and interventions. Surely, sound knowledge on dual LAD anomalies is a prerequisite for proper management of patients with coronary artery disease.In this study, we aimed to identify the frequency of dual LAD variations, and define the morphoanatomical features based on Spindola-Franco classification, using CT angiography. Appendageal subtypes of this variation were also documented and discussed. Methods PatientsThe study was approved by our institutional review board. A total of 1337 consecutive coronary CT angiography examinations performed in our department from April 2010 to December 2013 were retrospectively evaluated for dual LAD anomalies. These examinations had been performed for various reasons including, but not limited to, the assessment of coronary and cardiac morphology, electrocardiography (ECG) abnormalities, coronary bypass graft evaluation, coronary stent evaluation, coronary atherosclerosis evaluation and screening fo...

“…Due to its three-dimensional nature and the high soft tissue contrast, coronary MDCT angiography is an effective method for imaging the myocardial arterial supply [8] and to determine variations of coronary arterial supply patterns [20]. In this study, we could evaluate SANA and AVNA in all MDCT coronary angiography studies.…”

“…In the study by Ozturk et al ( 8 ) which studied the frequency of different types of dominance is determined that the frequency of left dominance in females was 8.3%, 3.7% with balanced and 88% with the right coronary dominance. Female gender is an independent predictor of morbidity and mortality after cardiac surgery and is included in most of the scores used for risk calculation ( 9 , 10 , 11 , 12 , 13 ).…”

Introduction:This study evaluated the frequency of domination of the coronary arteries types in patients treated by surgical myocardial revascularization. The aim of the study was to determine whether the left coronary circulation dominance is a prognostic factor for poorer outcome in patients undergoing coronary artery bypass surgery.Material and methods:A total sample consisted of 100 patients with coronary artery disease that were treated with coronary artery bypass grafting at the Clinic for Cardiac Surgery, Clinical Center of the University of Sarajevo. To all patients on the basis of preoperative coronary angiography was determined the dominance of the coronary arteries. Patients included in the study were divided into two groups, with the left and right with coronary dominance.Results:Left coronary dominance in a sample of patients was present in 21/100 (21%), right in 69/100 (69%) and balanced in 10/100 (10%) cases. Female gender was significantly more frequent in patients with left coronary dominance and proved to be a stronger predictor of poorer outcome, especially in combination with left main stenosis of the left coronary artery and left coronary dominance. Inability of revascularization of the r. interventricularis posterior (RIVP) was statistically significantly higher in case of left dominance 9/21 (42.9%), compared to the right 16/79 (20.3%), p=0.033. Lethal outcome was more common in case of left dominance in relation to the right (9.4% vs 0.9%). The incidence of surgical complications, respiratory, neurological and renal complications was not significantly different between groups, while the length of hospital stay was significantly higher in the group of patients with left dominance, p = 0.003.Conclusion:Left coronary dominance is an important risk factor for patients undergoing surgical myocardial revascularization.

Arterial supply of the posterior interventricular sulcus: a CT coronary angiographic study

Abstract: CCTA allows detailed assessment of the arterial supply of the PIS, and allowed to describe 25 subtypes. This information is of potential value to both cardiac surgeons and interventional cardiologists who plan bypass surgery or angioplasty aiming at the posterior interventricular artery.
