Giant pheochromocytomas (Pheo) are rare entities requiring clinical suspicion coupled with strategic diagnostic evaluation to confirm the diagnosis. The majority of cases are discovered incidentally. The diagnosis consists of biochemical evaluation and imaging study to localize the mass. Pathological examination confirms the diagnosis. The female patient in this case report presented with chest...

A 32-year-old man with a 20-year history of palpitation showed a short PQ interval and delta wave on 12-lead ECG. An electrophysiological study showed that the atrio-His (AH) and His-ventricular intervals were not influenced by rapid right atrial pacing or by bolus injection of adenosine triphosphate (ATP). The AH interval was shortened by coronary sinus ostium (CSos) pacing. Ventricular stimul...

Chylopericardium is a rare disease entity characterized by the accumulation of chylous fluid in the pericardial sac. It usually arises from mediastinal neoplasms, thrombosis of the subclavian vein, tuberculosis, nonsurgical trauma, thoracic or cardiac surgery. The spectrum of symptoms for chylopericardium varies from an incidental finding of cardiomegaly to dyspnea, upper abdominal discomfort, ...

Thyrotoxicosis along with its usual signs and symptoms like palpitation, weight loss, tremors, sweating, heat intolerance, diarrhea, exophthalmos, tachycardia, and warm extremities, can also present with gynaecomastia and as many as 80% of the patients may have histological evidence of gynaecomastia 1-4 . Although association of thyrotoxicosis with gynaecomastia is well documented, its presenta...

A 42-year-old man was referred to our hospital for an electrophysiologic study because of recurrent episodes of palpitation. On coronary angiogram, an anomalous atresia of the coronary sinus (CS) ostium was discovered. The ablation catheter was inserted from the right femoral artery to the accessory pathway (AP) of posterior paraseptal area. The earliest retrograde atrial activation was recorde...

A 30-year-old male visited the Cardiology Department of our hospital with dyspnea and palpitation complaints. 2/6 systolic murmur at the pulmonary focus and fixed split S2 were detected on auscultation. Right branch bundle block was observed on electrocardiography. On transthoracic echocardiography, the right heart cavities were dilated. SVASD was detected on transesophageal echocardiography. I...

PROPER MANAGEMENT of ventricular tachycardia (VT) should take into consideration: (1) the type of VT (nonsustained or sustained, monomorphic or polymorphic), (2) the probable electrophysiologic mechanism, (3) the anatomic and functional substrates (minimal or no structural heart disease or organic heart disease, normal or depressed ventricular function), and (4) the clinical presentation (palpi...

A 41-year-old man visited our hospital with the complaint of palpitation by atrial flutter. He was finally diagnosed as total anomalous pulmonary vein drainage by helical computed tomography (CT). This case is very unusual due to the lack of symptoms until the age of 41. The absence of pulmonary artery stenosis, and the presence of atrial septal defect providing sufficient right to left shunt f...

A 36-year-old man visited Yeungnam University Hospital with a sudden onset of palpitation, headache, and was found to be hypertensive. Chest radiography showed a 6 cm sized mass lesion on the posterior mediastinum. A biochemical study showed elevated levels of catecholamines. An I-123 metaiodobenzylguanidine scan revealed a hot uptake lesion on the posterior mediastinum. The patient was prepare...
