[A case of infective endocarditis with subtotal rupture of the posterior papillary muscle].

We recently experienced a case of infective endocarditis with multiple embolic complications. The patient was a 21-year-old male who was admitted to our hospital with high fever and dyspnea. Echocardiography showed vegetation on the aortic valve, severe aortic regurgitation and mild mitral regurgitation. Abdominal echography revealed large splenic infarction. First we performed aortic valve replacement and splenectomy. But infective endocarditis developed after surgery, and echocardiography revealed severe mitral regurgitation, which has been a change for the worse. After treatment with antibiotics, mitral valve replacement (the second surgery) was performed. Intraoperative findings were confirmative of subtotal rupture of the posterior papillary muscle. Histological examination of the subtotal ruptured muscle revealed presence of coagulation necrosis. The patient is healthy without recurrence of infective endocarditis after the second surgery. It is exceedingly rare to experience a case of surgically treated subtotal papillary muscle rupture due to infective endocarditis.

[Surgical treatment of atherosclerotic vascular diseases associated with coronary artery disease].

Selective coronary angiography to determine the incidence of coronary artery disease (CAD) has been performed in the 38 patients with atherosclerotic vascular disease. significant CAD was demonstrated in 17 of 23 (73.8%) patients with angina pectoris or previous myocardial infarction, in 4/15 (26.7%) patients who had no clinical evidence of CAD. There were no early and late postoperative death in the 9 patients who underwent simultaneous coronary artery bypass graft and vascular operations or percutaneous coronary angioplasty, on the other hand, there were one early and four late death in the 11 patients who underwent only vascular procedure.

Breast angiosarcoma metastatic to the maxillary gingiva. Case report.

A case of breast angiosarcoma metastatic to the maxillary gingiva is reported. A review of the literature revealed only three previously reported cases. Angiosarcomas often present as benign lesions. The surgeon should maintain a high level of vigilance when patients present with oral lesions and a history of breast tumor.

[Myocardial structure and left ventricular function in aortic valvular diseases].

In this study 13 patients with aortic stenosis (AS) and 19 patients with aortic regurgitation (AR) were analyzed to investigate the correlation between myocardial structure and left ventricular (LV) function. LV end-diastolic dimension (Dd), LV end-systolic dimension (Ds), LV Mass Index (LVMI), FS, mVcf and the normalized rate of change of LV dimensions during systole and diastole (-V/Dd, +V/Dd) were assessed using M-mode echocardiography before and after aortic valve replacement. The myocardial structures were investigated from the biopsied specimen in the operation using both light and electron microscopes. Then muscle fiber diameter (Diameter), the degree of interstitial fibrosis (%Fibrosis) and the myocyte volume fraction (%MF, %MT, %SA) were quantitatively evaluated by using a computerized system. And semi-quantitative analysis was made with electron microscopic score (EM-score). The results were as follows. 1. AS group: Left ventricular myocardial degeneration was mild. Significant positive correlationships were found between preoperative LVMI and Diameter (p < 0.01), and between the former and the volume fraction of the myofibrils (%MF) (p < 0.05). And significant positive correlationship was seen between Diameter and %MF (p < 0.05). However, no significant correlationship was seen between preoperative LVMI and %Fibrosis. Both LV systolic and diastolic function (-V/Dd, +V/Dd) showed significantly negative correlationship to LVMI preoperatively (p < 0.01, p < 0.05) and postoperatively (p < 0.05, p < 0.05). And in the patients with preoperative LVMI larger than 300 g/m2 and Diameter larger than 30 microns, +V/Dd was irreversible postoperatively. 2. AR group: EM-score in AR was significantly higher than that in AS (p < 0.05). Preoperative LVMI showed significantly positive correlationship to %Fibrosis (p < 0.01). And postoperative LVMI showed significantly positive correlationship to fibrous content (p < 0.01). Both LV systolic and diastolic function -V/Dd, +V/Dd) showed significantly negative correlationship to LVMI preoperatively (p < 0.05, p < 0.01) and postoperatively (p < 0.01, p < 0.01). And in the patients with preoperative LVMI larger than 300 g/m2 and %Fibrosis larger than 16%, both -V/Dd and +V/Dd were irreversible postoperatively. The above mentioned results indicated that preoperative LVMI and the morphologic parameters were useful to predict the reversibility of the postoperative LV function in both AS and AR.

[Report of three cases of emergency surgical salvage for acute pulmonary embolism].

Pulmonary embolism (PE) is one of the increasing diseases in Japan, which is aggravated rapidly and early diagnosis is necessary to improve its prognosis. We experienced three cases of successful surgical salvage. It is emphasized that the Doppler ultrasonic echocardiography plays important part in diagnosing PE early and noninvasively. Namely, it shows a appearance of acute cor pulmonale, and is usually able to guess the pulmonary artery pressure by using the simplified formula of Bernoulli's equation. We believe that the surgical pulmonary embolectomy under the cardiopulmonary bypass should be immediately considered in case of unsatisfactory conservative thrombolytic therapy.

[A case of the emergency salvage from the thrombotic occlusion of the Fontan conduit in tricuspid atresia].

The thrombotic occlusion of the Fontan conduit is one of the most fatal complications after Fontan procedure. Its survival case by the successful emergency surgery is reported. A 17-year-old male who had undergone Fontan procedure three years before for tricuspid atresia, using the expanded PTFE graft of 19 mm in internal diameter, had several episodes of palpitation due to probable paroxysmal atrial fibrillation. He suddenly complained chest oppression feeling and suffered paroxysmal atrial tachycardia following after atrial fibrillation. The radionuclide angiocardiography was performed immediately, which revealed clearly that the Fontan conduit had occluded by the thromboembolism in spite of the prophylactic anticoagulant therapy. Then the emergency surgery was performed successfully, in which the occluded Fontan conduit was replaced with another expanded PTFE graft of 20 mm in internal diameter under the extracorporeal circulation. It seemed that the inducement of this thrombotic occlusion of the Fontan conduit was paroxysmal atrial fibrillation. We emphasize the importance of the prevention of arrhythmias in the postoperative care of the Fontan procedure. Additionally we do emphasize the usefulness of the radionuclide angiocardiography which is available and non-invasive. Especially, first-pass study is much informative to elucidate the circulatory states in the cardiac anomalies.

A human skeleton from the Ohguruwa remains.

In 1941, the Ohguruwa remains were discovered at the Mizuho sports ground site in Nagoya. They date from about 3000 B.C., which is the early Jomon era. When the stadium was reconstructed in 1980, four human skeletons were found. Three of them, however, were in poor condition and moreover, were incomplete. However, the second skeleton was in good condition and could almost be reconstructed, and this skeleton (No. 2) was used for our study. It was found in the classic posture with arms and legs folded. Some pieces of a dog's skeleton were also discovered near the No. 2 skeleton's chest. This particular skeleton generally showed characteristics typical of the Jomon era. It had a stout structure and was judged to be a middle aged male because of the following features. There was considerable attrition of the occlusal surfaces on the remaining teeth. The teeth were worn flat, probably owing to the hard food and to their use as a tool. Both canines and first premolars of the upper and lower arches had been extracted in accordance with the custom of the time. Typical caries and localized periodontal breakdown were not observed, although there was horizontal alveolar bone loss, especially in the anterior regions. The mastoid process was extremely large and prominent. The lateral prominence of the mandible was developed. Analysis of lateral cephalogram revealed that the mandible was in the anterior position. The angles of SNA, SNB and ANB were 89.6 degrees, 89.2 degrees and 0.4 degrees, respectively. The skeletal pattern was definitive Class III. The adaptive changes in the teeth, their supporting tissues, temporomandibular joints and the related muscles--the harmonious masticatory system--were all estimated.

Topical PUVA, etretinate, and combined PUVA and etretinate for palmoplantar pustulosis: comparison of therapeutic efficacy and the influences of tonsillar and dental focal infections.

Twenty patients with palmoplantar pustulosis (PPP) were treated with topical PUVA, oral etretinate (Re), or combined PUVA and etretinate (Re-PUVA). Re and Re-PUVA treated sites improved and/or cleared more rapidly than PUVA treated sites. Complete clearance was observed in six of ten sites treated with Re-PUVA, two of ten with Re, and one of ten sites with PUVA within 12 weeks. UVA-control sites failed to be cleared within 12 weeks. Remission periods after stopping the treatment were 1.5 +/- 0.5 weeks (n = 2) with Re, 10.5 +/- 11.4 weeks (n = 6) with Re-PUVA, and one year (n = 1) with PUVA. These results overall suggested that Re-PUVA is the most effective treatment for PPP. Tonsillar focal infection (TFI) and dental focal infection (DFI) were found in 6/20 and 17/20 patients, respectively. However, the presence of focal infection (FI), TFI and/or DFI, did not appear to interfere with the therapeutic activities of Re and/or PUVA, because the complete clearance rates and remission periods in FI(+) patients were comparable with those in FI(-) patients.

[Elective prosthetic valve reoperation to relieve unacceptably high gradient].

Pressure gradients of Lillehei-Kaster valve (13 patients), Omniscience valve (26 patients) and Omnicarbon valve (7 patients) in the aortic position were evaluated by Doppler echocardiography. Twenty-three out of 46 patients revealed unacceptably high gradients. Seven prostheses were removed because the valve design that they had high gradients across them. Clinical findings including left ventricular function and symptoms improved after the reoperation. Patients who underwent aortic valve replacement with this series of valve prostheses should be followed up cautiously.
