Hoarseness associated with mitral stenosis was initially described by Ortner. Several cardiopulmonary conditions were associated with left recurrent laryngeal nerve palsy over the last 100 years; thus, the syndrome is termed as cardiovocal syndrome or Ortner's syndrome. This study aimed to classify the various predisposing conditions and to explain the(More)
BACKGROUND Prior cardiac surgery, especially the presence of coronary artery bypass grafts, is thought to preclude percutaneous epicardial access (EpiAcc) and, therefore, mapping and ablation. We evaluated the feasibility and safety of EpiAcc in patients with a prior cardiac operation. METHODS AND RESULTS We retrospectively analyzed all patients who(More)
BACKGROUND Stroke is the major cause of morbidity and mortality related to atrial fibrillation (AF). Catheter ablation for AF is effective in reducing AF burden, but its impact on long-term stroke risk is unknown. OBJECTIVE We sought to evaluate the periprocedural and long-term stroke risk after catheter ablation or cardioversion for AF. METHODS This(More)
BACKGROUND With the increasing use, complexity, anatomical approaches, and tools related to epicardial procedures, complications previously not seen during endovascular ablation are now well recognized with epicardial ablation. Whether newer approaches and the regional anatomy of the pericardial space contribute to unexpected complications after epicardial(More)
INTRODUCTION Catheter ablation of ventricular arrhythmia (VA) at the fibrous aortic mitral continuity (AMC) has been described, yet the nature of the arrhythmogenic substrate remains unknown. METHODS Procedural records of 528 consecutive patients undergoing ablation of VA at Mayo Clinic, Rochester, MN, were reviewed. The electrocardiographic and(More)
Question An 85 year old male presents to the emergency room with presyncopal episode associated with nausea and diaphoresis that lasted for 10 minutes. He has past medical history of hypertension and paroxysmal atrial fibrillation on anticoagulation. He also had complete AV block that necessitated the implantation of a dual chamber pacemaker (Medtronic(More)
