40 Years experience in mitral valve replacement using Starr-Edwards, St. Jude Medical and ATS valves.

Background: We have used the Starr-Edwards ball (S-E) valve since 1963, the St. Jude Medical (SJM) valve since 1978, and the ATS valve, since 1993 as the first choice of mechanical valve. In this study, the results with each valve during the 40 years were investigated in single mitral valve replacement (MVR) cases.

Efficacy of continuous low-dose human atrial natriuretic peptide given from the beginning of cardiopulmonary bypass for thoracic aortic surgery.

Purpose: Cardiac surgery performed under cardiopulmonary bypass (CPB) causes abnormalities of the renin-angiotensin-aldosterone system, resulting in decreased urine output and an accumulation of water in the third space. We studied the efficacy of continuous low-dose human atrial natriuretic peptide (hANP) in patients undergoing thoracic aortic surgery.

Methods: We divided 40 patients undergoing thoracic aortic surgery into two groups: the hANP group, which received 0.

A successfully operated case of prosthetic valve thrombosis during planned pregnancy.

The patient was a 29-year-old woman who, when she was an 8-year-old, had undergone atrial septal defect (ASD) closure and mitral valve replacement (MVR) using a Björk-Shiley valve (25 mm) for Lutembacher syndrome. Because of a planned pregnancy, warfarin had been replaced by heparin. During the 7th week of pregnancy, she was admitted to our hospital because of dyspnea.

Outcome of emergency conventional coronary surgery for acute coronary syndrome due to left main coronary disease.

Background: Outcomes of emergency coronary artery bypass grafting (CABG) for acute coronary syndrome (ACS) due to left main coronary (LMT) disease remain unclear. This study aimed to assess prognoses for patients undergoing emergency CABG for ACS due to LMT disease.

Methods: One hundred and four patients undergoing emergency CABG for ACS due to LMT disease were retrospectively reviewed.

Efficacy of a proton pump inhibitor given in the early postoperative period to relieve symptoms of hiatal hernia after open heart surgery.

Purpose: To evaluate the efficacy of a proton pump inhibitor, we retrospectively reviewed patients who underwent gastric fiberscopy (GFS) in the early phase after cardiac surgery.

Methods: The subjects were 103 patients who underwent GFS for poor appetite, gastric pain, heartburn, or hematemesis after cardiac surgery. We divided the patients into two groups: group I consisted of 49 patients who received an H2-receptor antagonist (ranitidine hydrochloride 300 mg/day), and group II consisted of 54 patients who received a proton pump inhibitor (PPI; sodium rabeprazole 10 mg/day) as prophylactic treatment.

Effects of pulsatile CPB on interleukin-8 and endothelin-1 levels.

Studies on pulsatile and nonpulsatile perfusion have long been performed. However, investigators have not reached a conclusion on which is more effective. In the present study, pulsatile cardiopulmonary bypass (CPB) was investigated in terms of the effects on cytokines, endothelin, catecholamine, and pulmonary and renal functions.

Comparative study of harvest-site complications following coronary artery bypass grafting between the radial artery and the saphenous vein in identical patients.

Purpose: The aim of this study was to assess the early outcome for complications associated with the radial artery harvest site, in comparison to using the saphenous vein, in patients harvested for both vessels.

Methods: During the last 2 years, 134 radial arteries were used in 133 patients, and the saphenous vein was also concomitantly used in 94 patients. We assessed the post-harvest forearm perception using a questionnaire that contained two statements regarding pain and numbness in those 94 patients.

Reoperation for ascending aortic aneurysm, coronary ostial aneurysm and patent Cabrol trick after bentall operation for aortitis syndrome.

A 38-year-old woman who had undergone an original Bentall operation in December 1995 for annuloaortic ectasia associated with ulcerative colitis required reoperation for ascending aortic aneurysm, coronary ostial aneurysm, and patent Cabrol trick. The initial Bentall operation included aortic root replacement using a valved conduit and reconstruction of the coronary arteries. Both coronary ostia were directly anastomosed to the composite valved graft, which was wrapped with the dilated aortic wall, and a Cabrol trick was added at the same time.

Valve dysfunction of the cloth-covered Starr-Edwards ball valve.

Background: Between June 1968 and March 1977, Starr-Edwards cloth-covered ball valves were used for valve replacement on a routine basis.

Methods And Results: Among the 66 operative survivors who underwent an isolated aortic or mitral valve replacement, 20 patients required reoperation 22 times because of valve dysfunction, thromboembolic complication, paravalvular leakage, hemolytic anemia, and/or prosthetic valve endocarditis. Reoperation was performed at a mean of 15.

Determining the best procedure for radial artery harvest: prospective randomized trial for early postharvest complications.

Objective: Although useful procedures for radial artery harvest have been reported, forearm circulation and collateral perfusion after radial artery harvesting remain unknown. To assess an optimal radial artery harvest technique for forearm circulation, we designed a prospective randomized trial.

Methods: Ninety patients were divided into 3 groups of 30 patients.

Surgical treatment for innominate artery aneurysm with a coronary pulmonary artery fistula: a case report.

A 50-year-old woman complained of hoarseness and chest X-ray demonstrated a widening of the superior mediastinum. Computed tomography scanning and aortography demonstrated aneurysmal dilatation at the innominate artery. Coronary arteriography showed a coronary pulmonary artery fistula originating from the left anterior descending artery.

Surgical results in acute type A aortic dissection.

Currently international registry data present the patient mortality with acute type A aortic dissection managed non-surgically to be 58%, and managed surgically to be 26%. Many articles consistently report the hospital mortality exceeding 20% in western countries. Many factors, such as cardiac tamponade and dissection-related organ malperfusion, contribute to hospital mortality and morbidity.
