[Pacemaker implantation in a patient with sick sinus syndrome, complicated with persistent left superior vena cava and absent right superior vena cava; report of a case].

A 78-year-old man was referred to our hospital with syncope and palpitation. A Holter electrocardiography (ECG) revealed sick sinus syndrome (SSS), and an enhanced chest computed tomography (CT) scan showed persistent left superior vena cava (PLSVC) and absent right superior vena cava. Myocardial leads and a pacemaker implantation were peformed through left anterior thoracotomy approach. There were only 10 reports of pacemaker implantation in a patient with SSS complicated with PLSVC and absent right superior vena cava in Japan. Open thoracotomy approach was thought to be usuful for these patients.
