A successful repair of tricuspid atresia by modified Björk's procedure--a case report.

A ten-year-old Japanese boy with tricuspid atresia type IB was treated by direct anastomosis from the right atrium (RA) to the right ventricle (RV), entirely with autogenous material. An incision of the RA anterior wall was designed for a flap of RA appendage. A valveless conduit was created, with this flap and a large piece of pericardium. Atrial septal defect (ASD) and ventricular septal defect (VSD) were closed with a patch. Cardiac catheterization and angiocardiography two months postoperatively, showed good results of the surgery.

Kay's mitral valve repair for mitral regurgitation due to ruptured chordae tendineae--clinical and hemodynamic observations.

Kay's mitral valve repair was performed in six consecutive patients with symptomatic mitral regurgitation due to ruptured chordae tendineae of the posterior leaflet. All patients including one with mild residual murmur showed a marked decrease in the heart size and significant clinical improvement. Postoperative hemodynamic studies, performed in four patients, showed restoration of normal or near-normal dynamics. The medium-term follow-up, 15 to 30 months after the operation, revealed continuing asymptomatic states in all. The function of the repaired valves was significantly better than that of the Hancock mitral bioprostheses. The advantages of this procedure compared with mitral valve replacement for the same condition were stressed.

Bentall's operation. A modification for coronary-graft anastomosis in an annuloaortic ectasia without displacement of the coronary origins.

Bentall's operation using a composite graft for complete replacement of an ascending aortic aneurysm and associated incompetent aortic valve is being widely used. In case of no displacement of the coronary origins, however, this technique often leads to difficulties in restoring the coronary flow. We now report a successful modification for this coronary-graft anastomosis.

Coenzyme Q10: the prophylactic effect on low cardiac output following cardiac valve replacement.

A randomized, prospective study of the effectiveness of preoperative administration of coenzyme Q10 on the prophylaxis of postoperative low cardiac output state was performed in 50 patients with acquired valvular diseases necessitating valve replacement. There were 25 patients in the treatment group and 25 in the control group. Patients in the treatment group received 30 to 60 mg of coenzyme Q10 orally for six days before operation. Preoperative clinical variables, operative procedures, total cardiopulmonary bypass time, and aortic cross-clamping time were similar for the two groups. Postoperatively, mild to severe low cardiac output state developed in 28 of 50 patients (56%) and necessitated the administration of considerable amounts of inotropic agent. The treatment group showed a significantly lower incidence of low cardiac output state during the recovery period than the control group (p less than 0.05). These results suggest that preoperative administration of coenzyme Q10 will increase the tolerance of human hearts to ischemia during aortic cross-clamping.

Lung function in adults with mycoplasmal pneumonia.

We prospectively studied on lung function of 17 patients (7 men and 10 women) of acute Mycoplasma pneumoniae pneumonia. Lung function tests including %VC, FEV1.0%, Peak flow, V75/HT, V25/HT, V50/V25 and MMF were measured during the acute and convalescent stage. The results showed dysfunction of peripheral airway because of reduction in V50/HT, V25/HT and MMF. It was suggested that lung function in patients with Mycoplasma pneumoniae pneumonia was impaired at the high lung volume as well as low lung volume.
