A 61-year-old woman had extracardiac unruptured aneurysms of the right and noncoronary sinuses of Valsalva, detected incidentally on electrocardiogram taken for a physical checkup. Two-dimensional echocardiography revealed that the sizes of the aneurysm of the right and noncoronary sinuses were 41×40 and 38×28mm respectively, but the shape of left coronary sinus was almost normal. The aortic valve leaflet was normal and the diameter of the aortic annulus and sinotubular junction was 23 and 27mm respectively. The Doppler color-flow echocardiogram showed moderate aortic regurgitation which resulted in prolapse of the right aortic cusp due to deformity of the annulus. We performed modified aortic root remodeling using a tailored Dacron graft to preserve the native aortic valve. Right and noncoronary sinuses of Valsalva were all excised with a small button of the aortic wall around the ostia of the right coronary artery. The left coronary sinus was left as it was. Then each commissure received sub-commissural annuloplasty and was pulled up. The defect of Valsalva was reconstructed with a 26mm Dacron tube graft, the proximal end of which was tailored to a scallop shape and that correspond to left coronary sinus was excised. The right coronary artery was reimplanted utilizing the Carrel patch method. Although we needed additional CABG to the right coronary artery and IABP support due to vasospasm of the right coronary artery, the postoperative course was uneventful. Echocardiography of the aortic valve before discharge showed a normal function without regurgitation.

A 31-year-old woman was admitted to our hospital with a sudden onset of chest pain and dyspnea. Echocardiography, chest CT, and chest MRI revealed a huge mass in the right atrium. She underwent pericardial drainage to alleviate cardiac tamponade. Emergency surgery was performed because of superior vena cava syndrome and the risk of tricuspid valve obstruction by the mass. The tumor was resected en bloc, including the right atrial wall and a large segment of the proximal superior vena cava. The right atrium was then reconstructed with a Xenomedica patch and the superior vena cava was reconstructed using an expanded polytetrafluoroethylene (ePTFE) vascular graft. The pathological diagnosis was haemangiosarcoma. Cardiac angiosarcoma is a rare tumor, and its prognosis is very poor. The patient could survive for about 5 months after surgical resection.

An 83-year-old man had acute type B aortic dissection combined with a large athelosclerotic abdominal aortic aneurysm (AAA) over 8cm in diameter. The dissection advanced into the wall of the AAA. The patient was treated with strict medical therapy for two months and successfully underwent an early elective abdominal aortic repair concomitant with off-pump aortocoronary bypass grafting. This strategy of meticulous medical management may improve clinical outcome for the acute phase in such rare cases.

In the past 9 years, 37 patients with infective endocarditis underwent valve replacement. The aortic valve was involved in 17 patients, the mitral valve in 10, and both valves in 10, respectively. 35 patients had native valve and 2 had prosthetic valve endocarditis. Bacterial findings were Streptococcus in 20 patients (54%), Staphylococcus in 5 (13.5%), gram-negative in 3 (8%), and undetected in 10 (27%). 10 patients developed aortic annular abscess. After aggressive debridement of all apparently infected tissue of annular abscess, the defects left in the left ventricular outflow tract were repaired by interrupted mattress sutures with pledgets in 4 patients, by autologous pericardial patch in 4, and by valved conduit in 2 PVE patients, respectively. Retrograde cardioplegic infusion from the coronary sinus not only facilitated operative manipulation but also provided superior myocardial protection in such patients. Operative mortality was 11% (4/37). Reoperation was necessary in 2 patients; one for periprosthetic leak, and the other for newly developed severe left coronary ostial stenosis after the first operation, but both died eventually. Late mortality was 8% (3/37). Mean follow-up of 31 months was achieved in all 30 survivors, in whom there was no recurrence of infection and clinical improvement was excellent.

PURPOSE: High tibial valgus osteotomy (HTO) is a well-established surgical procedure for patients with medial compartment osteoarthritis (OA) of the knee. The hybrid closed-wedge HTO (CWHTO) procedure permits extensive correction in patients with severe deformities or patellofemoral joint OA. The aim of this study was to report the short-term results in a consecutive series of patients treated with hybrid CWHTO. MATERIALS AND METHODS: We retrospectively evaluated the clinical outcomes and radiographic parameters in 29 consecutive knees that underwent hybrid CWTHO to correct medial compartment OA at an average follow-up of 52.6 months. Clinical outcomes were assessed using the Lysholm score and knee scoring system of the Japanese Orthopedic Association (JOA). The Kellgren-Lawrence grading system and pre- and postoperative mechanical axis (MA), femorotibial angle (FTA), posterior tibial slope, and patella height were assessed. RESULTS: The FTA and MA significantly changed from 180.7° to 170.4° and from 22.0° to 60.2°, respectively. No significant differences were observed between the mean pre- and postoperative posterior tibial slope, Insall-Salvati ratio, or Caton-Deschamps index. The postoperative JOA and Lysholm scores significantly improved from 76.7 to 95.8 and from 58.8 to 90.2, respectively. CONCLUSIONS: Satisfactory outcomes can be achieved with hybrid CWHTO in patients with medial OA.

Background/Aims:
Gastric acid secretion is suspected to be a pivotal contributor to the pathogenesis of functional dyspepsia. The present study investigates the potential association of the gastric acid secretion estimated by measuring serum pepsinogen with therapeutic responsiveness to the prokinetic drug acotiamide.
Methods:
Dyspeptic patients consulting participating clinics from October 2017 to March 2019 were prospectively enrolled in the study. The dyspeptic symptoms were classified into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). Gastric acid secretion levels were estimated by the Helicobacter pylori infection status and serum pepsinogen using established criteria and classified into hypo-, normo-, and hyper-secretion. Each patient was then administered 100 mg acotiamide thrice daily for 4 weeks, and the response rate to the treatment was evaluated using the overall treatment efficacy scale.
Results:
Of the 86 enrolled patients, 56 (65.1%) and 26 (30.2%) were classified into PDS and EPS, respectively. The estimated gastric acid secretion was not significantly different between PDS and EPS. The response rates were 66.0% for PDS and 73.1% for EPS, showing no significant difference. While the response rates were stable, ranging from 61.0% to 75.0% regardless of the estimated gastric acid secretion level among subjects with PDF, the rates were significantly lower in hyper-secretors than in non-hyper-secretors among subjects with EPS (42.0% vs 83.0%, P = 0.046).
Conclusion
Although acotiamide is effective for treating EPS as well as PDS overall, the efficacy is somewhat limited in EPS with gastric acid hypersecretion, with gastric acid suppressants, such as proton pump inhibitors, being more suitable.
