BACKGROUND Atrial fibrillation is common among older persons. Catheter ablation is increasingly used in patients for whom medical therapy has failed. METHODS AND RESULTS We conducted a retrospective cohort study of all fee-for-service Medicare beneficiaries ≥65 years of age who underwent catheter ablation for atrial fibrillation between July 1, 2007, and December 31, 2009. The main outcome me...
BACKGROUND Catheter ablation has become an established treatment modality for a broad spectrum of ventricular tachycardias (VTs). We analyzed incidence and predictors of major complications of VT ablation procedures in a high-volume expert center. METHODS AND RESULTS We evaluated 548 consecutive patients who underwent 722 ablation procedures, 473 (65.5%) for structural heart disease VT in the...
BACKGROUND Thromboembolism due to atrial fibrillation (AF) is a frequent cause of stroke. More than 90% of thrombi in AF form in the left atrial appendage (LAA). Obliteration of the appendage may prevent embolic complications. METHODS AND RESULTS We evaluated the feasibility and safety of implanting a novel device for percutaneous left atrial appendage transcatheter occlusion (PLAATO). LAA oc...
A 71-year-old man who had undergone coronary artery surgery (coronary artery bypass graft) 9 years previously was admitted to a peripheral hospital with sudden-onset chest pain and progressive dyspnea. Clinical examination revealed reduced basal air entry and crepitations suggestive of heart failure. His ECG demonstrated new-onset atrial fibrillation and T-wave depression in leads , aVL, and V2...
INTRODUCTION Localized pericardial constriction is a rare form of constrictive pericarditis CP. Depending on the CP location, clinical presentation may be variable, including compression and obstruction of right ventricular inflow tract(RVIT), coronary obstruction, or pulmonary stenosis. CASE PRESENTATION A 72-year-old man presented a 2-year history of dyspnea and atrial fibrillation. A contr...
BACKGROUND The implantation of left atrial appendage closure device (WATCHMAN, Boston Scientific, Natick, MA) is an alternative option to oral anticoagulation (OAC) for stroke prevention in atrial fibrillation. Patients require short-term OAC after implantation to avoid device thrombosis. The 2 clinical trials that assessed this device excluded patients thought not to be candidates for OAC. As ...
BACKGROUND The most common complication of coronary artery perforation, a rare complication of percutaneous coronary intervention (PCI), is hemopericardium with cardiac tamponade. However, localized extra-coronary bleeding can lead to epicardial hematoma, which is a rare phenomenon. We report the case of an unusual delayed presentation of post-PCI hematoma with unrecognized guidewire perforatio...
Rapidly progressive dyspnea developed in a 73-year-old male patient with maintenance hemodialysis. His heart sounds were diminished. Heart rate was 102 bpm, and blood pressure was 92/53 mm Hg. Pulsus paradoxus of 20 mm Hg was present. Three months earlier, the patient had undergone extracorporeal membrane oxygenation-assisted percutaneous coronary intervention to implant 4 drug-eluting stents f...
Chemodectoma is a neoplasm arising from the carotid and aortic bodies, having neuroectodermic origin. It has been related mainly in human beings and dogs. Among the later, the brachiocephalics are the most susceptible, mainly the ones older than six. This case reports a seven year old, maie Boxer dog, presenting convulsion and dry cough. The animal died and it was sent to the Pathological Anato...
