Mitral commissurotomy is the treatment of choice for mitral stenosis. If this is not feasible, replacement of the valve becomes necessary. Open commissurotomy has been performed at Loyola University Medical Center, Maywood, Ill, in 105 patients since 1970. The mean age was 45 years. The indication for surgery was heart failure in 92 of the cases. Sixty of the patients were in class 3 of the New York Heart Association (NYHA) classification. Eighty-five underwent open mitral commissurotomy alone. This was not feasible in 42 patients scheduled for it who required valvular replacement. Twenty-five patients had a left atrial thrombus. Two patients died, one from aortic dissection and the other from acute infarction in the perioperative period. Ninety-eight patients are NYHA class 1 or 2 at present. Two patients required valvular replacement following the commissurotomy. The low mobidity and mortality with excellent long-term results support our contention that open mitral commissurotomy is the treatment of choice for mitral stenosis.

Brucella endocarditis is a rare, but often fatal, complication of brucellosis. A 32 year old man acquired brucellosis while on a visit to his former home in Greece and presented six months later with malaise, fever and aortic regurgitation. Blood cultures grew Brucella melitensis biotype 1. Combined chemotherapy with streptomycin, tetracycline and rifampin sterilized his blood; however, his aortic valve was replaced owing to recurrent emboli and cardiac failure. Over the next 18 months the patient's antibody titer to Brucella fell and his blood reamined sterile. Cure was achieved by resection of the infected aortic valve and 10 weeks of bactericidal therapy for B. melitensis.

During January 1982 to June 1989, there were 105 evaluable adult cases of native valve infective endocarditis admitted to Department of Medicine, Siriraj Hospital. The incidence was approximately 2.6 per 1,000 admissions. The male to female ratio was 1.4 and the mean age was 31.6 years. Thirty (28.5%) were cases associated with intravenous drug abuse. All non-addicts had pre-existing cardiac lesions susceptible to endocarditis especially rheumatic mitral regurgitation, aortic regurgitation, VSD and PDA. The clinical features of cases without intravenous drug abuse were low grade fever for few weeks, malaise, dyspnea and heart murmur. The addicts with endocarditis presented with acute febrile illness and pulmonary symptoms. Mucocutaneous embolic lesions were detected in one third of the patients. Echocardiography detected vegetations in 50 per cent of the patients. Streptococci were the most common causative agent in 93 per cent of non-addicts whereas the same percentage in addicts were caused by S. aureus. Most of the patients were treated with beta lactams (pen G, ampicillin or cloxacillin) alone or combined with aminoglycosides (streptomycin or gentamicin) for a duration from 10 days to 16 week. Six cases had valve replacement operation due to intractable heart failure and valve ring abscess, 2 had embolectomy of major arteries and 2 had craniotomy due to intracerebral hemorrhage. The overall case fatality rate was 14 per cent. The causes of death were heart failure, cerebral complications and severe pulmonary infections. Clinical response was observed sooner in non-addict patients.

Heart transplantation (HTx) has now become an accepted treatment modality for end-stage heart disease. The limited supply of suitable donor organs imposes constraints upon the decision of who should be selected for transplantation. Usually patients are candidates for HTx, who remain NYHA functional class III or IV despite maximal medical therapy. Further criteria are low left ventricular ejection fraction (less than 20%) with heart rhythm disturbances class IIIA-V (LOWN), which are associated with poor prognosis. Additionally, the suffering of the patient and also the course of heart failure are essential for judging the urgency of HTx. Contraindications are absolute in patients with untreated infections, fixed pulmonary vascular resistance (PVR) above 8 WOOD-degrees, severe irreversible kidney and liver disease, active ventricular or duodenal ulcers and acute, psychiatric illness. HTx is relatively contraindicated in patients with diabetes mellitus, age over 60 years, PVR above 6 WOOD-degrees and an unstable psychosocial situation. To prevent rejection of the transplant heart, live-long immunosuppressive therapy is needed. Most immunosuppressive regimes consist of Cyclosporine A and Azathioprine (double drug therapy) or in combination (tripple drug therapy) with Prednisolone. For monitoring of this therapy, control of hole blood cyclosporine A level and white blood count is needed. Rejection episodes can be suspected if there is a greater than 20 mmHg decrease of systolic blood pressure, elevated body temperature, malaise, tachycardia or heart rhythm disturbance. The diagnosis of cardiac rejection can be established by endomyocardial biopsy. Measurement of the voltage of either the surface or intramyocardial ECG, echocardiography with special consideration to early left ventricular filling time as well as immunological methods are additionally used tools. Graft sclerosis as the main risk factor of the late transplant period remains an unsolved problem.

The patient responded to treatment at the first onset of heart failure but gradually became irresponsive to treatment, experiencing fatigue and malaise as the chief complaints and suffering from gradually progressive decrease in exercise capacity and body weight. Dose of DOA gradually increased to maintain well clinical state of the patient. Unusual for heart failure, he had bradycardia as the basal rhythm without showing a tendency for tachycardia. Cardiac catheterization revealed pulmonary hypertension and low cardiac output, however, left ventricular ejection fraction was 37%. There were no notable changes in ultrasonic cardiogram or CTR through the clinical course. Tl-201 myocardial images and pulmonary perfusion images showed gradual worsening corresponding to progressive worsening of clinical state. From these findings, the patient was determined as a candidate for heart transplantation.

A case of Erysipelothrix rhusiopathiae endocarditis involving the aortic and mitral valves in a 70-year-old male farmer is reported. The onset of infection was insidious, with a five-month history of low grade fever, malaise and a 20 kg weight loss. The patient eventually developed severe heart failure requiring surgery and died postoperatively of Pseudomonas aeruginosa pneumonia. In vitro studies showed the isolate to be highly susceptible to penicillin, ciprofloxacin and ofloxacin, and resistant to vancomycin.

A retrospective survey of patients with pneumococcal infective endocarditis at the University Hospital, Leiden, over a 10-year period (1976-1986) yielded five cases. Applying strict case definitions, four patients had definite and one patient possible pneumococcal endocarditis. The commonest presenting signs and symptoms were malaise, fever, and congestive heart failure. Predisposing conditions were previous splenectomy in one case and a valve prosthesis in another. The aortic valve was the most common site of infection. In four of the five patients the diagnosis of endocarditis was made during life. These patients were treated appropriately, i.e. with antibiotics to which S. pneumoniae is sensitive. In three patients, surgical intervention was performed in the acute phase because of progressive heart failure. Paravalvular abscesses were observed at surgery in all these cases. The four patients treated in our series recovered fully; the single fatal case constituted an unrecognized case of pneumococcal endocarditis. If recognized and treated appropriately (particularly with early selective surgery) endocarditis can be cured. In a statistical analysis of 36 patients with pneumococcal endocarditis reported during the past five years, we found a significantly higher occurrence and mortality in men than in women; no other clinical features were associated with a poor outcome of illness.

An 82-year-old woman was admitted to Iwamizawa Rosai Hospital, Cardiovascular Medicine, for detailed examination of an aneurysm of abdominal aorta. CT scan revealed marked swelling of para-aortic lymph nodes which regressed spontaneously in three months. She was re-admitted to our hospital because of general malaise and gait disturbance. Her chest X-ray on the second admission revealed miliary disseminated shadows, which were confirmed to be tuberculous granuloma by lung biopsy. She was initially well controlled with anti-tuberculosis drugs, followed by severe liver dysfunction and pancytopenia, and died of respiratory and cardiac failure. At autopsy, wide-spread malignant lymphoma and miliary tuberculosis of the lung were found. The cause of liver dysfunction was strongly suspected to be due to infiltration of the lymphoma cells to portal triads of the liver. Hemophagocytosis found in the bone marrow, spleen and liver might be consistent with clinically so-called "hemophagocytic syndrome", causing pancytopenia, associated with infection.

A case of Takayasu's disease presenting in a young man as a solid abdominal mass is described. The literature is reviewed and classifications of the disease are discussed. Occlusive thromboaortopathy, also known as "pulseless disease" or Takayasu's disease, was first described in 1908 by Takayasu, who observed cataracts and peculiar arteriovenous anastamoses around the optic papillae in a young woman. It is a vasculitic disorder of uncertain etiology occurring mainly in young women and may involve part or most of the aorta, as well as the pulmonary artery. Early features include fever, malaise, weight loss, and a high ESR, and, later on, absent pulses, aneurysms, hypertension, and heart failure may occur. The authors describe an unusual case of Takayasu's disease in a young black South African man.

The combination of nifedipine and atenolol must be evaluated in terms of risks and benefits to the hypertensive patient. Disadvantages with single-agent therapy justify trials of combination regimens. beta-Blockers may be unacceptable to some patients because of gastrointestinal upset, musculoskeletal symptoms, tiredness, malaise, insomnia, depression or confusion, sweating, breathlessness or cold extremities. The side effect profile varies from patient to patient and between different beta-blockers. Calcium antagonists also have characteristic side effects, including severe headaches, flushing and oedema, tachycardia and possibly worrying palpitations, and polyuria. Combining a calcium antagonist and a beta-blocker can reduce some side effects; for example, tachycardia is offset by addition of beta-blocker to calcium antagonist therapy, and beta-blocker-induced cold extremities may be reversed with a drug such as nifedipine. Moreover, the antihypertensive efficacy is increased, which is useful in previously resistant patients. However, an excessive fall in blood pressure is a possible adverse effect of the combination. There is also the possibility of precipitating heart failure in patients with cardiomegaly and severely compromised left ventricular function. The combination of nifedipine and atenolol was evaluated in 25 patients in a randomised, crossover trial following a month's treatment with atenolol 50mg twice daily. Patients received either atenolol 50mg twice daily alone, or atenolol 50mg twice daily with sustained release nifedipine 20mg or 40mg twice daily, or placebo twice daily during three 4-week treatment periods. Additional antihypertensive benefit was obtained by addition of the low dose of nifedipine compared with atenolol alone, but no further advantage was obtained with the higher nifedipine dose.(ABSTRACT TRUNCATED AT 400 WORDS)
