Abstract

Objective: Sinoatrial node (SAN) artery originates from proximal segment of right coronary artery (RCA) or from left circumflex artery. Sinoatrial node artery artery originating from posterolateral (PL) branch of RCA is very rare. Only several cases have been reported. The study was performed to seek the frequency of this variation, evaluate clinical relevance, and describe electrocardiographic, angiographic characteristics of patients. Methods: Consecutive 1500 coronary angiography were screened to detect specifically SAN artery originating from PL branch of RCA. Patients with this variation were followed-up for one year regarding the arrhythmic events. Results: The origin of SAN artery was proximal RCA in 1280 (85%), circumflex artery in 208 (14%), and PL branch of RCA in 12 (0.8%) patients (8 male, 4 female, mean age 64±9 years). There was no history of arrhythmia in all patients. One patient presented with atrioventricular block. Indications of angiography were stable angina in 5, unstable angina in 5, and acute myocardial infarction in 2 patients. The patient with inferior myocardial infarction due to RCA total occlusion did not develop bradycardia or conduction defect. In four patients (33%) there was another artery originating from proximal RCA, ending at same territory with the variant artery suggesting dual blood supply. During one-year follow-up none of the patients experienced arrhythmic event. Conclusions: Sinoatrial node artery originating from distal RCA is very rare. This variation, even in patients with severe RCA disease is not associated with severe arrhythmia. Dual blood supply may be a protective factor in this subgroup of patients from arrhythmic events. To be aware of the origin and course of variant SAN artery may provide safe approach to interventional cardiologist and cardiac surgeon during percutaneous and surgical coronary and atrial interventions.

Özet

Amaç: Sinoatriyal nod (SAN) arteri sağ koroner arter (SKA) proksimal segmenti ya da sol sirkumfleks arterden çıkar. Sağ koroner arterin posterolateral dalından (PL) çıkan SAN arteri oldukça nadirdir. Bu güne kadar sadece bir kaç olguda saptanmıştır. Araştırma bu varyasyonun sıklığını saptamak, klinik önemini değerlendirmek ve bu varyasyona sahip hastaların elektrokardiyografik, anjiyografik özelliklerini tanımlamak amacıyla planlanmıştır. Yöntemler: Ardışık 1500 koroner anjiyografi özellikle SKA PL dalından çıkan SAN arterini tespit etmek amacıyla tarandı. Bu varyasyona sahip hastalar aritmik olaylar açısından bir yıl takip edildi. Bulgular: Sinoatriyal nod arteri çıkış noktası 1280 hastada (%85) proksimal SKA, 208 hastada (%14) sirkumfleks arter ve 12 hastada (%0.8) SKA PL dalı olarak saptandı (8 erkek, 4 kadın, ort yaş 64±9 yıl). Hastaların hiçbirinde daha önce aritmi hikayesi yoktu. Bir hastada AV tam blok mevcuttu. Koroner anjiyografi endikasyonları 5 hastada kararlı angina, 5 hastada kararsız angina ve 2 hastada akut miyokard infarktüsüydü. Sağ koroner arteri tam tıkalı olan alt duvar infarktüslü hastada bradikardi ya da ileti kusuru gelişmedi. Dört hastada (%33) proksimal SKA'den çıkan, varyant SAN ile aynı bölgede sonlanan ve bu nedenle ikili kanlanmayı düşündüren ikinci bir arter mevcuttu. Bir yıllık takiplerde hiçbir hastada aritmik olay gelişmedi. Sonuç: Sağ koroner arter distal segmentinden çıkan SAN arteri oldukça nadirdir. Bu varyasyon ciddi SKA darlığı olanlarda dahi ciddi aritmi ile beraber değildir. İkili kanlanma bu alt grupta aritmik olaylardan koruyucu bir faktör olabilir. Sinuatriyal nod arterinin çıkış noktası ve seyrinin farkında olmak girişimsel kardiyologlara ve kalp cerrahlarına perkütan koroner girişimler, aritmi tedavileri ve cerrahi atriyal işlemlerde güvenli bir yaklaşım sağlayabilir.
