A case of congenital rhabdomyoma of the heart in a 5-month-old Korean infant is described. The patient presented with a congenital supraventricular tachyarrhymia that was detected in utero by fetal sonography. The tumor was multiple, but no obvious association with tuberous sclerosis complex was demonstrated. Microscopic examination revealed classic "spider cells" with rich glycogen content. Ultrastructurally, the cells contained numerous leptofibrils, clumped Z band material, and desmosome-like cell junctions. The case is a second documented case of cardiac rhabdomyoma in this country, and its presentation as an etiological factor of supraventricular tachycardia is a very unusual manifestation.

A patient with non-ischaemic cardiomyopathy, and pre-existing atypical atrial flutter and left bundle branch block, developed broad complex tachycardia. In this unique and uncommon case of double tachycardia, we discuss the diagnostic approach of ventricular tachycardia in patients with broad complex tachycardia, and the use of different contemporary algorithms to help diagnose ventricular tachycardia and differentiate it from supraventricular tachycardia with aberrant conduction.

In order to assess the diagnostic value of invasive electrophysiologic study (EPS) in the patients with unexplained syncope, the electrophysiologic findings of 268 patients with unexplained syncope despite a complete clinical evaluation were analyzed. Results showed positive EPS finding was 38% in total patients and 50% in the patients aged > 70 years. With increasing age, the diagnostic yield of EPS also increased. No significant differences of complication rate were found among the different age groups. It was concluded that EPS have high diagnostic value in the patients with unexplained syncope. Its complications are few and mild. EPS may be recommended in elderly patients with unexplained syncope.

PURPOSE: The significant drastic complications of performing laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients are gastric staple line leakage and bleeding. The aim of our study is to evaluate the efficacy of the clinical data for detecting postoperative complications after LSG. METHODS: The study enrolled 150 consecutive patients who underwent LSG from January 2003 to July 2006. When abnormal data (heart rate > or = 10/min, or temperature > or = 7.5degrees C) was detected on postoperative day 1, then laboratory tests (blood, urine, chest X-ray and abdominal sonogram) and water soluble gastrografin UGIS were performed to detect the postoperative complications after LSG (group A). The patients who had normal postoperative clinical data (group B) were compared with group A. RESULTS: Of the 150 patients who underwent LSG, 9 patients (6%) had postoperative complications. Two patients had major complications: 1 case of leakage (0.6%) and 1 case of delayed bleeding (0.6%), and 4 patients had minor complications in group A. But no major complications were detected in group B (P<0.01). The heart rate and body temperature in group A were significantly faster and higher than those in group B (P<0.01). Especially, 2 patients who had major complications had severe tachycardia over 120 beats per minute (bpm). However, when the body temperature of a patient was elevated, there was no high grade fever in all the cases ( > 39degrees C). CONCLUSION: Evidence of tachycardia or a high body temperature may be useful to detect major complications after LSG. We also recommend performing laboratory test and UGIS when clinically indicated.

Ventricular premature complexes (VPCs) are known to be one of the most benign cardiac arrhythmias when they occur in structurally normal hearts. We experienced a 32-year old man who presented with dyspnea, palpitations and very frequent VPCs (31% of the total heart beats). Echocardiography revealed a dilated left ventricle (LV 66 mm at end-diastole and 57 mm at end-systole) and a decreased ejection fraction (34%). Very frequent VPCs had been detected 10 years previously and he underwent a failed radiofrequency catheter ablation (RFCA) procedure at that time. The patient had been treated with heart failure medications including betablockers, ACE inhibitors and spironolactone for the two most recent years. Six months after we eliminated these VPCs with a second RFCA procedure, the heart returned to normal function and size. Long standing and very frequent VPCs could be the cause of left ventricular dysfunction in a subset of patients who suffer with dilated cardiomyopathy, and RFCA should be the choice of therapy for these patients.
