Nonsurgical transthoracic epicardial ablation for the treatment of a resistant posteroseptal accessory pathway

A case of Wolff-Parkinson-White syndrome successfully treated by transcutaneous epicardial radiofrequency ablation is described in a patient with a posteroseptal accessory pathway who had failed prior attempts of conventional endocardial and coronary venous system approaches. Simultaneous endocardial and pericardial space mapping was performed and only ablation from the pericardial space was successful, suggesting an epicardial course of the accessory pathway.Universidade Federal de São Paulo, Paulista Sch Med, Dept Clin Cardiac Electrophysiol, BR-04024002 São Paulo, BrazilUniversidade Federal de São Paulo, Paulista Sch Med, Dept Clin Cardiac Electrophysiol, BR-04024002 São Paulo, BrazilWeb of Scienc

Bidirectional ventricular tachycardia with alternating right and left bundle branch block morphology in a patient with metastatic cardiac tumors

A case is reported of bidirectional ventricular tachycardia and syncope in a 16-year-old male with a previous history of a paratesticular rhabdomyosarcoma that achieved complete remission with treatment. At the electrophysiological study, frequent ectopy of both right and left bundle branch block pattern were present, with runs of monomorphic and bidirectional VT alternating the two morphologies. the study suggested a single focus at the interventricular septum with two exit sites, depolarizing the right and left ventricle in an alternate fashion. Reassessment of the malignancy status showed multiple cardiac metastases with a 4 mm nodule at the interventricular septum.Fed Univ São Paulo, Paulista Sch Med, Dept Clin Cardiac Electrophysiol, São Paulo, SP, BrazilFed Univ São Paulo, Paulista Sch Med, Dept Clin Cardiac Electrophysiol, São Paulo, SP, BrazilWeb of Scienc
