Objective: We tested the hypotheses that volume overload and cyanosis observed in the pre-Fontan single ventricular circulation are associated with increased ventricular fibrogenesis, that the Fontan procedure helps to reduce fibrogenesis, and that persistently increased fibrogenesis in the Fontan ventricle is associated with ventricular diastolic dysfunction.
Methods: Levels of serum amino-terminal procollagen type III, a marker of tissue fibrogenesis, were measured in 172 patients with single ventricle circulation and 149 controls. Patients were divided into 3 groups according to surgical stage: 59 patients after Blalock-Taussig shunt or pulmonary banding, 60 patients after Glenn surgery (Glenn group), and 53 patients after Fontan surgery (Fontan group).
Chylothorax is a serious complication of congenital cardiac surgery and is significantly associated with increased morbidity and mortality. Central venous obstruction, which is often related to the insertion of central venous catheters for postoperative management, is known to be an important risk factor for treatment failure and mortality associated with this condition. We present the case of a 6-month-old girl with refractory chylothorax after surgical repair of tetralogy of Fallot.

The aim of this study was to test the hypothesis that pulmonary arterial wall properties and hemodynamics are abnormal after the resolution of KD. Pulmonary arterial input impedance was measured during cardiac catheterization (4.

Methods: We report a patient in whom premature closure of FO in fetal life was associated with late clinical onset of mitral valve stenosis and subsequent development of irreversible pulmonary hypertension (PH).
Results: The patient showed persistent PH after birth, which completely regressed at the age of 8 months.
Stent implantation is an effective alternative to surgery and balloon angioplasty for the treatment of stenotic vascular lesions. However, there is concern about the hemodynamic consequences related to the loss of vascular elasticity caused by the non-compliant property of the implanted stent. Here we report data for pulmonary vascular impedance and right ventricular performance after implantation of balloon-expanded stents for peripheral pulmonary stenosis in a 13-year-old girl with repaired pulmonary atresia and ventricular septal defect.

Methods And Results: The study involved consecutive pediatric patients (n = 118) with various heart diseases who either had a central venous catheter in the cardiac intensive care unit or underwent cardiac catheterization. The maximum (IVCD(max)) and minimum (IVCD(min)) diameters of IVC were measured on ultrasound simultaneously with measurements of mean CVP.
Objective: To evaluate the efficacy of primary treatment for ovarian cancer from overall survival and progression-free survival.
Patients And Methods: A total of 28 patients with epithelial ovarian cancer in stages III and IV who were primarily treated in our ward from 1993 were examined retrospectively. The Kaplan-Meier method and Harrington-Fleming test were carried out for the cumulative survival rate and analysis.
