Figure 4.
Representative fluoroscopic images of successful ablation sites in two patients with Mahaim-type accessory pathway of 17 patients. (A) The fluoroscopic images in a patient with right-sided MAP. (B) Solid circles show radiofrequency ablation targets around the tricuspid and mitral annuli. There were 13 patients showing MAPs around the tricuspid annulus, but for most patients they were located at the free wall. In total, four patients had them around the mitral annulus, but in most of the patients, it was located at the free wall. The dot was represented as his bundle. (C) The fluoroscopic images in a patient with left-sided MAP. ABL, ablation catheter; CS, coronary sinus; L, patient with left-sided Mahaim; LAO, left anterior oblique; R, patient with right-sided Mahaim; RAO, right anterior oblique; RV, right ventricular.
