Approximately 100 kinds of Foods for Specified Health Use (FOSHU) are used to “control postprandial elevated blood glucose level”. In this review, we describe their safety and effectiveness.

We performed aortic remodeling using a tailored Dacron graft (Yacoub's procedure) in two cases of root aneurysm combined with aortic regurgitation. The cases were 20-year-old and 45-year-old women. The leaflets did not coapt at a central portion, but the lack of coaptation did not produce significant prolapse. No organic change was found, so we attributed aortic regurgitation to sinotubular junction. Remodeling of the root was selected as the operative procedure because degeneration in the annulus was unlikely in these two cases. All three sinuses were excised, with 3mm of the arterial wall left above the aortic annulus and a small button of the aortic wall around the ostia of the coronary arteries. Then each commissure was pulled up and the height of the commissure was measured. The proximal end of the graft was then tailored to a scallop shape, so that the top of the scallop matched the commissure level. The graft was then sutured to the aortic rim with continuous 5-0 polypropylene sutures. Both coronary arteries were reimplanted utilizing the Carrel patch method and the distal graft anastomosis was completed. The aortic crossclamp times were 147 minutes and 163 minutes and the total pump times were 166 minutes and 189 minutes. One patient has mild or 1+ aortic regurgitation on postoperative echocardiogram and aortography, but she has no activity restrictions, and no evidence of congestive symptoms. Yacoub's remodeling procedure which spares the aortic valve, requires no anticoagulant therapy in the post-operative period. Aortic valve-sparing replacement of the aortic root is an excellent procedure for any patient with an ascending aneurysm and an anatomically salvageable valve. Although further long-term follow-up is required, we believe that preserving the native aortic valve is useful for preventing complications associated with mechanical valves.

During the past 7 years from January 1991 through October 1997, we treated 30 cases of aortic root reconstruction by the Carrel patch method. The cases included annulo-aortic ectasia (AAE), root aneurysm with aortic regurgitation (AR), aortic dissection with AR, and true aneurysm (ascending and arch) with AR. The surgical treatment consisted of 28 modified Bentall operations and 2 aortic root remodelings, similar to the Yacoub operation. The aortic root and valve were resected, the coronary arteries were dissected free, mobilized, and then implanted into the composite graft. Coronary anastomosis was performed by mattress suture reinforced by Teflon felt strips. In 5 cases it was necessary to undergo coronary artery bypass grafting for myocardial ischemia. Blood transfusion was unnecessary in 11 cases. Post operative death was seen in only one patient who underwent an emergency operation for cardiac tamponade due to aortic dissection on the 25th postoperative day. The operative mortality rate was 3.3%. The complications of anastomosis, for example leakage and dilatation of the coronary ostia, were not seen in our experience. Reoperation and late death were not observed during the follow-up period (average 23 months). Cerebral hemorrhage occurred in only one case, at 5 years after the operation, and all other patients had an uneventful postoperative course. The event-free rate is 75% (n=1) at 6 years. The operative procedure is considered feasible in any anatomic variation of aortic root diseases, even if dislocation of the coronary ostia is minimal, and this method holds hope for the prevention of anastomotic pseudoaneurysm formation and long-term survival. Although further long-term follow-up study is necessary, our experience suggests that the Carrel patch procedure has few late term complications.

An 84-year-old woman with severe aortic stenosis (AS) and coronary artery disease (CAD) was admitted repeatedly with syncope and heart failure. Due to her comorbidities, concomitant transapical transcatheter aortic valve replacement (TAVR) and off-pump coronary artery bypass grafting (OPCAB) were performed. She did well postoperatively. CAD is often found concurrently in patients presenting with severe symptomatic AS. Concomitant TAVR and OPCAB is considered as a less invasive and more feasible treatment option in high-risk patients.

A 58-year-old man who complained of dyspnea on effort was given a diagnosis of decompensated congestive heart failure. Echocardiography revealed severe aortic regurgitation and cardiomegaly. We decided to perform aortic valve replacement with a mechanical valve, however his past history made us suspicious of allergy to metal. From his previous patient records, we determined he was allergic to many metals : gold, iron, platinum, cobalt, chrome, bronze, and zinc. Newly performed skin patch tests showed positive reactions to aluminum, tin, palladium, indium, iridium and stainless steel. We selected a CarboMedics mechanical valve made of nickel-titanium alloy. Aortic valve replacement with a 27-mm CarboMedics mechanical valve was performed by median sternotomy. At sternum closure, we used polyester non-absorbable suture thread, instead of surgical steel wire, because it contains stainless steel. His postoperative progress was good and he was discharged on the 10th postoperative day. One year after surgery he is doing well without any allergic symptoms.

A 34-year-old woman was admitted with a history of syncope and a mass was detected in the right atrium (RA) by transthoracic echocardiography (TTE). Preoperative chest computed tomography (CT) also demonstrated an RA tumor measuring 4×3 cm. We performed resection of the RA tumor under cardiopulmonary bypass. Histopathological findings showed that the tumor was an angiomyolipoma. It is well known that angiomyolipomas are most frequently found in the kidney and are associated with tuberous scleroses. There was no evidence of tuberous sclerosis in this case. Primary tumors of the heart are rare. However, there have been a few intracardiac angiomyolipomas reported previously.
