We report a case of atrioventricular reentrant tachycardia (AVRT) with ostial atresia of the coronary sinus (CS). Without the anatomic angiography, radiofrequency (RF) energy was applied at the mitral valve annulus and the bypass tract was eliminated. After the therapy procedure, by CS angiography, we knew the persistent left superior vena cava (PLSVC), and the coronary sinus was connected with vena cava superior, very thin in a diameter. The therapy procedure was successful. The patient has remained completely symptom free.
