“…Origination of the LMCA outside the coronary sinus, above the junctional zone is referred to as a high takeoff (11,18,19). Montaudon et al (18) stated that the LMCA originating from the proximal 1-cm segment of the ascending aorta might be considered as a normal variant, while a takeoff distal to the first 1-cm segment of the ascending aorta should be considered as an anomaly.…”

The small dimensions and rapid movement of coronary arteries have made their evaluation with computed tomography (CT) challenging. However, because of the dramatic development of multislice CT (MSCT) technology in the last decade, coronary CT angiography (CTA) has become an increasingly important noninvasive modality in the diagnosis of coronary artery diseases. High temporal and spatial resolution capabilities of MSCT scanners enable detailed 3D visualization of complex coronary artery anatomy without motion artifact.To be able to interpret the coronary CTA correctly, radiologists should be familiar with normal anatomy, anatomic variants, and anomalies of the coronary arteries and their cross-sectional appearances. In this study, we aimed to identify the 64-slice CTA appearance of the anatomic variations and anomalies of the coronary arteries and determine their incidence in a population of 700 patients. Materials and methodsCT data of 700 patients (405 males, 295 females; age range, 17-85 years) who underwent 64-slice coronary CTA in our institution were retrospectively reviewed to identify the coronary anatomy and determine anatomic variants and anomalies. Patients were referred for coronary CTA because of known or suspected coronary artery disease (CAD). The institutional review board approved the study. CT scanAll CT examinations were performed by a 64-slice CT scanner (Aquillon 64, Toshiba Medical Systems, Tochigi, Japan) with retrospective ECG gating (scan protocol is given in Table 1). Patients with a heart rate greater than 75 beats/min were premedicated with an oral dose of 40 mg propronalol one hour before the scan. Sublingual nitroglycerine was delivered to the patient just before the scan. For venous access, an upper extremity vein (antecubital vein of the right arm) and a 20-gauge IV cannula was used. A total of 80-85 mL of contrast media with high iodine concentration (≥350 mg/mL) was injected with a flow rate of 5 mL/s, followed by a 20 mL saline chaser. The scan timing was determined with automated bolus tracking technique by placing the region of interest over the proximal descending aorta and setting the trigger threshold to 180 HU.Raw spiral CT data were reconstructed in various phases of the cardiac cycle to obtain images with the highest quality (without motion artifact). Reconstruction performed at 75% of R-R interval was found to be optimal for image analysis in most patients. Image analysisImages reconstructed at the optimal phase were transferred to another workstation (Vitrea 2 workstation, Vital Images Inc., Plymouth, Minne- CARDIOVASCULAR IMAGING PURPOSETo retrospectively review the 64-slice computed tomography (CT) appearance of coronary artery anatomic variants and anomalies and determine their incidence in 700 patients. MATERIALS AND METHODSCT data of 700 patients who underwent 64-slice CT angiography (CTA) because of known or suspected coronary artery disease were retrospectively reviewed by two radiologists experienced in cardiovascular radiology.

“…Se ha descrito que la aortografía, puede facilitar su demostración angiográfica cuando un ostium coronario no puede ser cateterizable dada su "ausencia" en un primer intento 13 . La TC y la RM son muy útiles para el estudio tridimensional de las ACA y su relación con los grades vasos 5,12,14,15 .…”

“…Therefore, it is important to know that such anomalies exist before performing an invasive procedure for the left coronary arteries. [17,18] The absence of the LMCA has been reported at around 0.41-0.52% in several studies, [16][17][18] but Cademartiri et al [19] reported an incidence rate of 3.3%. In our study, the absence of the LMCA in combination with the associated origin of the LAD and Cx from the left sinus valsalva via separate ostiums was observed in only one case (1.2%).…”

Bul gu lar: Sağ dominans, sol dominans ve kodominans oranı sırasıyla %80.7, %8.4 ve %10.8 idi. Konus arterin %16.86 oranında sağ sinüs valsalvadan ve %83.1 oranında sağ koroner arterden (sağ KA) köken aldığı gözlemlendi. Sinüs nod arterin (SNA) %77.1 oranında sağ KA'dan, %18.1 oranında sirkumfleks (Cx) arterden, %2.4 oranında sol ana koroner arterden (sol ana KA) ve %2.4 oranında sağ sinüs valsalvadan köken aldığı belirlendi. Hastaların %30.12'sinde ramus intermedius mevcuttu. Kırk sekiz hastada (%57.8) koroner arter anomalisi saptandı. Bu hastaların %1.2'sinde sol ana KA noksanlığı; %6'sında komissural köken; %1.2'sinde koroner hipoplazi; %4.8'inde kontralateral sinüs köken anomalisi ve %43.3'ünde miyokard köprüsü mevcuttu.So nuç:128 kesitli BT, koroner arter varyasyonlarının ve anomalilerinin saptanmasında güvenilir, ayrıntılı ve doğru bilgi sağla-yan invaziv olmayan bir yöntemdir. 128 kesitli BT'nin koroner arter anomalilerinin tanı ve cerrahi tedavisinde yüksek öneme sahip olduğu kanısındayız.Anah tar söz cük ler: Anjiyografi; anomali; bilgisayarlı tomografi; koroner damarlar; tanı.Background:In this study, we aimed to investigate the efficacy of a 128-slice computed tomography (CT) device in detecting anatomical variations and anomalies of coronary arteries and to compare the results obtained with literature data.
