PURPOSE: Patients requiring urethral reconstruction due to failed hypospadias repairs present a considerable technical challenge. Herein we report the experience of redo urethroplasties for complicated recurrent hypospadias. MATERIALS AND METHODS: From 1987 to 1997, we performed redo urethroplasty in 11 cases with complicated recurrent hypospadias. Types of recurrent hypospadias were coronal (1 case), distal shaft (4 cases), mid-shaft (1 case), and penoscrotal (5 cases) hypospadias. The interval between the last operation and redo operation was distributed from 8 months to 5 years. We analysed preoperative status, operative methods and their complications retrospectively. RESULTS: We performed urethroplasties using scrotal skin flap or buccal mucosal graft in only 2 cases. In spite of a paucity of usable penile skin, we performed urethroplasties with maximal use of remaining penile skin. Mathieu method was used in one case with coronal type. Mustarde operation was used in 4 cases with distal shaft hypospadias. And in 5 cases with penoscrotal type, we used Thiersch-Duplay method. Six of 11 patients had complications such as urethrocutaneous fistulas (4 cases) or recurrent hypospadias (2 cases) which were managed successfully later. CONCLUSIONS: Urethroplasty using penile skin maximally such as Mathieu, Mustarde, or Thiersch-Duplay methods appears to achieve success in patient with recurrent hypospadias subsequent to previous failed repairs.

BACKGROUND: Transcatheter closure of patent ductus arteriosus, using the Rashkind double umbrella occluder system, had been attempted in mulitcenter since non-surgical closure of patent ductus arteriosus by Rashkind. METHODS: Between July 1991 and June 1993, transcatheter closure of patent ductus arterious was attempted in 20 adult patients(21 trials). RESULTS: Seventeen female and 3 male patients was consisted of the study. The patient age ranged from 17 to 54 years(mean 30+/-9 years). Mean pulmonary artery pressure before closure was 18.5+/-6.0mmHg(range from 10mmHg to 30mmHg). The diameter of ductus ranged from 3.5mm to 8.0mm(mean 5.2+/-1.5mm), as determined by contrast injection through 11F Mullin sheath or 7F catheter. There was significant decrease of Qp/Qs from 2.6+/-1.1 to 1.5+/-0.4 immediately after transcatheter closure of ductus(p<0.01). There was significant decrease of left ventricular end-diastolic dimension by echocardiogram from 58.7+/-7.6mm to 53.6+/-6.5mm after transcatheter closure of ductus(p<0.01). Among the 21 cases, 16 cases(76.2%) had the clinical improvement without the support of surgical closure. One 17mm Rashkind umbrella was retrieved because of position and problem of deployment. There was no device embolic experience in 21 cases. There were 2 cases of hemolytic anemia during the follow-up period ; one case was surgically ligated and another 17mm device was implanted in the other case. CONCLUSIONS: Transcatheter closure of patent ductus arteriosus in adult patients can replace the surgical correction in selected patients.

A 46-year-old man presented to our institution with inappropriate implantable cardioverter-defibrillator (ICD) shock delivery. The ICD (single chamber, dual shock coils) was implanted for sustained monomorphic ventricular tachycardia with unstable hemodynamics and underlying systolic left ventricular dysfunction. ICD interrogation revealed recurrent episodes of ICD shock due to noise sensing and increased impedance of right ventricular (RV)-lead. With the impression of lead fracture, ICD lead extraction was performed. The fractured ICD lead was completely removed by traction of locking stylet and counter-traction of polypropylene dilator sheath. A new lead was inserted and the patient was discharged without complications after 2 days. To our knowledge, this is the first report on ICD lead extraction by conventional traction and counter-traction technique in Korea.

Pacemaker lead endocarditis is treated with total removal of the infected device and proper antibiotics. The outcomes of patients undergoing percutaneous lead extraction for large vegetations (>2 cm) have not yet been shown. In this case report, we present two patients with pacemaker lead endocarditis with large vegetations of maximum diameter 2.4 cm and 3.2 cm. The first patient had multiple vegetations attached to the tricuspid and mitral valves and developed septic emboli to the brain, lung, and liver. The second patient had a large, persistent vegetation on the tricuspid valve, even two weeks after complete removal of the leads. Both patients were successfully treated with transvenous pacemaker lead removal and antibiotics.

Torsades de Pointes is a life-threatening arrhythmia associated with a number of causes, but is very rare among endocrinologic disorders. We report a case of male pseudohermaphroditism with hyperaldosteronism due to a 17alpha-hydroxylase deficiency presented with sudden cardiac arrest.

In hypertrophic cardiomyopathy, the distribution and extent of left ventricular hypertrophy is known to be variable. Among the subtypes of hypertrophic cardiomyopathy, midventricular obstruction is a rare variant of obstructive hypertrophic cardiomyopathy. This variant is at higher risk of apical wall motion abnormality and/or infarction. We report 4 patients with midventricular obstructive hypertrophic cardiomyopathy who presented with chest pain. Significant systolic pressure gradients between basal and apical chamber of left ventricle were documented by cardiac catheterization and Doppler echocardiography in all patients, and left ventricular apical infarction was noted in one of them. During mean follow-up period of 32 months(21 months to 5 years), one patient with apical infarction died of malignant ventricular arrhythmia.
