Tuberculous aneurysm of the aorta is an extremely rare disease with a high mortality rate. Only 32 patients treated surgically have been reported in the literature. These reports indicate an 84.4% operative survival rate. We present a case of a tuberculous false aneurysm in the descending thoracic aorta that was successfully treated surgically with an(More)
We report an elderly woman with multiple sclerosis who showed an extensive cavity formation in the midthoracic cord in addition to multiple abnormal intensity signals in the central nervous system on magnetic resonance imaging (MRI). The cavity decreased in size in response to corticosteroid therapy with an improvement in neurological symptoms. The autopsy(More)
BACKGROUND Few studies have explored risk stratification of arrhythmic events in patients with ischemic heart diseases according to T-wave alternans (TWA) using modified moving average (MMA) method and heart rate turbulence (HRT). METHODS AND RESULTS A retrospective analysis of 63 patients who underwent MMA-based TWA and HRT divided the patients into 3(More)
Calcium antagonists, nicorandil and long-acting nitrates are highly effective for preventing coronary spasm. The withdrawal of coronary vasodilators, especially calcium antagonists, is risky in cases of vasospastic angina. We herein present a case of cardiopulmonary arrest that occurred due to coronary spasm triggered by the discontinuation of coronary(More)
BACKGROUND Diaphragmatic electrogram recording during cryoballoon ablation (CB-A) of atrial fibrillation is commonly used to predict phrenic nerve palsy (PNP). OBJECTIVE The purpose of this study was to investigate a novel method for predicting PNP at an earlier stage to prevent sustained PNP. METHODS A total of 197 patients undergoing CB-A were(More)
BACKGROUND As the technique for radiofrequency catheter ablation for atrial fibrillation (AF) has progressed, so has our knowledge of both normal and abnormal anatomy of the left atrium and pulmonary veins (PV). We treated several AF patients with accessory conduction pathways (ACP) who were also found to have a common ostium of inferior PVs (CIPV), a(More)
