Out of 104 patients with perimembranous or infundibular-isolated ventricular septal defect (VSD), causative factors of Prol and AR, and the operative indication were studied in 17 with prolapse of the aortic cusp (Prol) and 10 with aortic valve regurgitation (AR). The left to right shunt ratio and the size of VSD were smaller in patients with Prol or AR than in those with the normal aortic cusp, suggesting that hemodynamics might take part in the cause of Prol or AR. Twenty-two patients underwent VSD closure only, four valvuloplasty and one aortic valve replacement. Residual AR was occurred in three out of ten patients. After surgery, AR was disappeared in six out of seven patients with the first grade preoperative AR, but AR remained in all two patients with the second grade preoperative AR. Careful preoperative observation and early operation before the appearance of AR are the important factors for avoiding residual regurgitation after aortic valvuloplasty.

Surgical interventions for aorto-iliac obstructive diseases were studied through the operative results. Eighteen patients underwent aorto-femeral bypass (AOF) and 23 who were over 70 years of age or who had serious preoperative complications had axillofemoral bypass (AXF). No perioperative death occurred in AOF patients, while the mortality rate of AXF patients was 8%. Postoperative ankle pressure indexes were significantly higher in AOF patients than in AXF patients. Follow-up graft patency rate was 100% in AOF patients at 54 months (mean), and 85% in AXF patients at 44 months respectively. AOF should be the first choice for patients with aorto-iliac obstructive disease, and AXF is suitable only for high-risk patients.

A 51-year-old woman, who had undergone mitral valve replacement with the Starr-Edwards ball valve 21 years ago, was hospitalized with cardiac failure. Preoperative cineangiograms showed delay of the ball movement during the early diastolic phase. Re-replacement of the mitral prosthetic valve with a CarboMedics prosthetic valve and tricuspid annuloplasty was successfully performed. The postoperative period after the initial implantation of the Starr-Edwards ball valve is the longest among patients reported in Japan. The cause of prosthetic valve insufficiency may have been granulomatous hyperplasia on the valve seat.

PURPOSE: Endoscopic diagnosis of gastric cancer (GC) that emerges after eradication of Helicobacter pylori may be affected by unique morphological changes. Using comprehensive endoscopic imaging, which can reveal biological alterations in gastric mucosa after eradication, previous studies demonstrated that Congo red chromoendoscopy (CRE) might clearly show an acid non-secretory area (ANA) with malignant potential, while autofluorescence imaging (AFI) without drug injection or dyeing may achieve early detection or prediction of GC. We aimed to determine whether AFI might be an alternative to CRE for identification of high-risk areas of gastric carcinogenesis after eradication. MATERIALS AND METHODS: We included 27 sequential patients with metachronous GC detected during endoscopic surveillance for a mean of 82.8 months after curative endoscopic resection for primary GC and eradication. After their H. pylori infection status was evaluated by clinical interviews and ¹³C-urea breath tests, the consistency in the extension of corpus atrophy (e.g., open-type or closed-type atrophy) between AFI and CRE was investigated as a primary endpoint. RESULTS: Inconsistencies in atrophic extension between AFI and CRE were observed in 6 of 27 patients, although CRE revealed all GC cases in the ANA. Interobserver and intraobserver agreements in the evaluation of atrophic extension by AFI were significantly less than those for CRE. CONCLUSIONS: We demonstrated that AFI findings might be less reliable for the evaluation of gastric mucosa with malignant potential after eradication than CRE findings. Therefore, special attention should be paid when we clinically evaluate AFI findings of background gastric mucosa after eradication (University Hospital Medical Information Network Center registration number: UMIN000020849).
