Severe pulmonary vascular disease consisting of ventricular septal defect and patent ductus arteriosus. A case diagnosed as the indication for total correction by the hemodynamic study.

A 12-year-old girl with ventricular septal defect, patent ductus arteriosus and pulmonary hypertension was hemodynamically diagnosed as the indication for total correction by the initial cardiac catheterization. However, histologic assessment by lung biopsy revealed the terminal stage of plexogenic pulmonary arteriopathy, i.e.

Histologic findings of ductus arteriosus and pulmonary vascular disease in interrupted aortic arch.

There are still a number of unsolved problems concerning the total correction of interruption of the aortic arch. Here we report a histopathological investigation of the patent ductus arterious and pulmonary vascular disease using autopsy material of a patient with Celoria type B interruption of the aortic arch who died postoperatively. The so-called ductus arteriosus between the pulmonary arterial trunk and the descending aorta was lacking in elastic fibers and smooth muscle cells at the media showing discontinuous, transverse fibrous tissue.

Successful surgical correction in two patients with tricuspid atresia using autologous pericardial valve-bearing tube graft.

A modification of the Fontan procedure has been used successfully to correct tricuspid atresia in two children who had severe hypoplasia of pulmonary artery. In the first patient (who had functioning Gleen anastomosis) the hypoplastic left pulmonary artery was widened by an angioplasty, and then a Dacron external conduit containing an autologous pericardial valve (an autologous pericardial valve-bearing tube graft) was positioned to lead from the right atrial appendage to the left pulmonary artery. A large secondum type atrial septal defect was closed by a Dacron patch.

Surgical treatment for hypoplastic left heart syndrome: case reports.

A 58-day-old girl with hypoplastic left heart syndrome underwent bypass grafting from the pulmonary artery to the descending aorta, ligation of the ductus arteriosus, and banding of the main pulmonary artery distal to the graft. Anastomoses of the graft were performed by partial clamping of the arteries under moderate surface hypothermia. The patient tolerated the procedure well and was discharged from the intensive care unit on the eleventh postoperative day, but she died on the twentieth day of metabolic derangement.

Surgical treatment of annuloaortic estasia: experience in 7 consecutive patients.

Seven patients with annuloaortic ectasia were treated according to the method described by Bentall and De Bono. A Björk-Shiley valve in a composite graft was the prosthesis of choice and was used in all patients except 1, who received a Starr-Edwards valve. Profound topical cooling without selective coronary perfusion was applied in 5 patients for myocardial preservation during aortic occlusion.
