RESUMO
INTRODUCTION: Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the superior venous system that may be discovered at the time of cardiac implantable electronic device (CIED) implantation. METHODS AND RESULTS: We present a subject who needed cardiac resynchronization therapy (CRT)-CIED implantation and was discovered to have PLSVC with absent innominate vein during the implant procedure. We were able to successfully implant a CRT-CIED using a right-sided approach via the right superior vena cava (SVC). We present a description of our implant technique and a brief review of the different aspects of CIED implantation in subjects with variants of PLSVC. CONCLUSION: Superior venous anomalies such as PLSVC can make CIED implantation technically challenging. However, with increasing operator experience, cardiac imaging and appropriate tools successful CIED implantation is possible in almost all cases.
RESUMO
We present a case of cardiac lipofibromatosis associated with atrial fibrillation and complete heart block requiring permanent pacemaker implantation. Multimodality cardiac imaging including transthoracic echocardiography and cardiac magnetic resonance were useful for tissue characterization of this rare cardiac diagnosis.

Idiopathic ventricular tachycardia (VT) is usually a benign arrhythmia with good prognosis that can be managed with antiarrhythmic agents and is often cured using ablation. There is, however, a malignant potential in a subset of patients with idiopathic VT as was the case for our patient whom we discuss in this case report. After a review of the medical literature, and to our knowledge, this is the first case of a successful idiopathic VT ablation in an adult while extracorporeal membrane oxygenation was being used.
