Background Isolated single coronary artery (SCA) is an extremely rare congenital coronary anomaly. Some subgroups of SCA can lead to angina pectoris, acute myocardial infarction or even sudden death in the absence of atherosclerosis. Young patients, especially, have the risk of serious clinical events, but middle-aged-to elderly patients have a variable clinical course. Methods and Results The aim of this study was to present the clinical and angiographic properties, relatively long-term follow-up (54 14 months) and management of adult patients (mean age 57 12 years) with SCA. The records of 70,850 patients undergoing coronary angiography between 1999 and 2005 were reviewed. Ten patients (0.024%) were found to have SCA, originating from the left sinus of Valsalva in 3 (30%) patients and from the right sinus of Valsalva in 7 patients (70%). No atherosclerotic involvement was seen in 7 (70%) patients. One patient was also treated by stent implantation to the SCA. Other patients were followed medically. All patients have been followed uneventfully. Conclusion Medical treatment is usually adequate for middle-aged to elderly patients with SCA in the absence of ischemia and/or acute coronary syndrome.
Origin and Distribution Anomalies of the Left Anterior Descending Artery in 70,850 Adult Patients: Multicenter Data Collection

Objectives: To present the clinical and angiographic properties of the left anterior descending artery anomalies. Background: Coronary artery anomalies are discovered in less than 1% of angiography series. Since the number of angiographies and coronary bypass operations are increasing significantly every day, these anomalies are of clinical importance. However, data about left anterior descending artery anomalies in literature is still scarce. Methods: We reviewed the records of 70,850 patients who had undergone coronary angiographies at 4 different cardiology center from 1999 to 2005 years. Results: Major congenital coronary anomalies were discovered in 171 of these cases (0,24%). The mean age of these patients was 61 +/- 11 (18-84) years. Ninety nine patients (58%) were male. Left anterior descending artery was involved in 12 patients (0.017%). In nine patients with the anomalous LAD there were concomittant congenital coronary artery anomalies. Concurrent coronary artery anomalies encountered were double left anterior descending artery type 4 (2 cases), double left anterior descending artery type 4 with double right coronary artery (1), double right coronary artery (1), double circumflex artery with anomalous left anterior descending artery (1), circumflex artery from right sinus of Valsalva (1), separate septal perforator and myocardial bridging of posterior descending artery (1), intercoronary communication, and ostial atresia of the left anterior descending artery and anomalous circumflex artery (1). Conclusion: Our series is the biggest series where relatively sufficient clinical and angiographic information about the LAD anomalies were provided. (c) 2006 Wiley-Liss, Inc.
Relationship Between Slow Coronary Flow and Left Atrial Appendage Blood Flow Velocities
(Blackwell Publishing, 2007) Demirbag, Recep; Gur, Mustafa; Yilmaz, Remzi; Arslan, Sukru; Guler, Niyazi
Aims: This study was undertaken to assess whether slow coronary flow (SCF) is related to low left atrial appendage (LAA) blood flow velocities. Methods: Study subjects consist of 44 patients with SCF and 11 volunteer subjects with normal coronary angiogram. The diagnosis of SCF was made using the TIMI frame count method. The blood flow velocities were obtained by placing a pulsed-wave Doppler sample volume inside the proximal third of the LAA. Results: The mean LAA emptying velocities (MEV) were significantly lower in patients than control subjects (34.5 +/- 9.9 cm/sec vs 84.0 +/- 12.1 cm/sec; P < 0.001). In bivariate analysis, significant correlation was found between MEV, and systolic pulmonary venous flow, mean TIMI frame count, deceleration time, and isovolumetric relaxation time (P < 0.05). By multiple linear regression analysis, mean TIMI frame count (ss =-0.865, P < 0.001) was identified as independent predictors of MEV. Conclusion: This study indicates that SCF phenomenon may be related to low LAA blood flows.
