We report a case of rhabdomyosarcoma involving the mitral valve of a 57-year-old female. She was referred to our hospital for progressive orthopnea and edema. Chest X-ray showed marked cardiomegaly and pulmonary congestion. Echocardiogram revealed solid mass in left atrium involving the mitral valve. Emergency operation was required because of acute heart failure. At the operation, the mitral orifice was obstructed by the tumor arising from the left atrium. After partial resection of the left atrium, mitral valve replacement with a Carpentier-Edward prosthesis was performed. Subsequently microscopic examination diagnosed as rhabdomyosarcoma. She died three months after the operation of heart failure probably due to progression of the remnant of the tumor. This, to our knowledge, is the first case of mitral valve replacement for a primary rhabdomyosarcoma of the heart in Japan.

A 57-year-old man was admitted with dyspnea and bloody sputum. The chest X-ray showed unilateral alveolar infiltration, and alveolar cell carcinoma was suspected. Physical examination showed orthopnea and a loud systolic murmur, and the echocardiogram showed mitral valve prolapse. A chest X-ray 4 days later revealed bilateral infiltration. The cardiac catheterization showed pulmonary congestion and the capillary wedge pressure revealed a prominent V wave. Papanicolaou's test of sputum was negative. These findings suggested heart failure due to mitral regurgitation rather than lung carcinoma. The patient underwent mitral valve replacement because of his refractoriness to the medical treatment. During the operation, the chordae tendineae of the anterior mitral leaflet was found to be completely ruptured. The mechanisms of unilateral pulmonary edema could not be ascertained, but the effect of posture and gravity was thought to be a possible mechanism.

A 65 year-old-man was admitted to our hospital complaining of orthopnea and precordial oppressive feeling. Chest roentgenogram revealed congestive heart failure. Electrocardiogram revealed acute myocardial infarction-like pattern. Serum enzymes (CPK, GOT, LDH) were slightly elevated, but serum antiviral antibodies were not elevated. Echocardiogram showed severe symmetrical left ventricular (LV) hypertrophy, but there was no abnormality of LV wall motion. He died of progressive heart failure and ventricular fibrillation on the second hospital day. A necropsy was performed within one hour of death. The heart was enlarged (690 g) with both left and right ventricular hypertrophy. The myocardium disclosed a diffuse infiltration predominantly of eosinophilic leucocytes. Histopathological study revealed giant cell formation and granulomatous lesions in the myocardium. There was no overt endocarditis or pericarditis. We concluded that the severe LV hypertrophy was due to myocardial inflammatory swelling. From these findings, we diagnosed this case as acute isolated (Fielder's) myocarditis.

A large-scale, prospective, 8-week, office-based study was conducted to evaluate the effects of adding captopril to a therapeutic regimen of diuretic and digoxin or diuretic alone in the management of patients with mild to moderate congestive heart failure (CHF). A total of 2218 primary care physicians evaluated 6669 patients over the study period for efficacy parameters, which included changes in a modified New York Heart Association (NYHA) functional classification, symptomatology, and daily activity levels. Overall, 63.8% of evaluated patients improved with regard to functional ability, with 19% improving two or more modified NYHA classes. Symptoms of CHF, including dyspnea on exertion, fatigue, and orthopnea and signs, including rales and peripheral edema, were reduced in 86% of these patients: 41.5% demonstrated mild improvement; 30.0%, moderate improvement; and 14.5%, marked improvement. Three parameters, with which patients reported having difficulty at study entry, were assessed serially to evaluate changes in functional capacity; 78.5% of patients reported an increased walking distance, 72.3% had increased capacity for climbing stairs, and 60.2% had improved capacity for individual recreational activities. Adverse experiences were reported in 18.1% of all patients; 4.9% of patients withdrew from the study because of an adverse effect. Combination therapy with captopril and diuretic for CHF was shown to be safe and effective regardless of patient age (less than 70 years vs. greater than or equal to 70 years), duration of heart failure (less than 1 year vs. greater than 1 year), presence of digoxin treatment, or the dosing schedule employed.(ABSTRACT TRUNCATED AT 250 WORDS)

The response of patients with chronic severe heart failure to extended infusions (greater than or equal to 48 hours) of milrinone was evaluated in a multicenter, baseline-controlled, phase III efficacy and safety trial in 189 patients in the United States. Milrinone was given as loading and maintenance infusions according to one of four dose regimens. An effective response was defined as greater than or equal to 20% increases in cardiac index or decreases in pulmonary wedge pressure. All loading doses (range, 37.5 to 75 micrograms/kg/10 min) were effective short term, and maximum response occurred at 15 minutes. For the three effective regimens, cardiac index increased initially (at 15 minutes) by 24% to 42%, and pulmonary wedge pressure decreased by 24% to 33%. Systemic vascular resistance was reduced by 15% to 31%. The maximal acute response was effective in 99% of individual patients. During maintenance therapy, effective responses were seen at infusion doses of 0.375, 0.50, and 0.75 micrograms/kg/min, whereas an infusion of 0.25 micrograms/kg/min was ineffective. During 2 days of maintenance therapy, cardiac index remained augmented by 34% to 39% for the low and intermediate doses and by 44% to 73% for the high-dose infusion regimen. Pulmonary wedge pressure decreased an average of 18% on day 1 and 30% on day 2. Systemic vascular resistance was reduced by 20% to 25%, and stroke work index was augmented by 21% to 58%. Symptomatic improvement was common during intravenous milrinone therapy for symptoms of dyspnea (61% response), orthopnea (63%), edema (62%), and fatigue (40%). Improvement occurred more frequently in those with worse baseline functional indexes and in those with greater hemodynamic responses to therapy. Safety and tolerance were exceptionally good for these patients with advanced heart failure.(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 71 patients with cardiac failure requiring diuretic treatment were randomly allocated to receive either 20 mg frusemide/2.5 mg amiloride or 0.25 mg cyclopenthiazide/8.1 mmol sustained release potassium once daily for 12 weeks. Of the 35 patients treated with cyclopenthiazide/potassium, in 47% of patients the daily dose was doubled compared with in only 30% of the 36 patients treated with frusemide/amiloride. Both treatments significantly improved crepitations, oedema, orthopnoea and patient self-assessments of dyspnoea on effort; there were no significant differences between the two treatments. Plasma potassium concentrations were unaffected by either treatment and there were no clinically significant changes in laboratory data. Of the five patients receiving frusemide/amiloride and of the eight receiving cyclopenthiazide/potassium who withdrew from the trial, three and four, respectively, were due to possible drug-related effects. It is concluded that frusemide/amiloride is efficacious and acceptable for the treatment of congestive heart failure.

Two patients with similar symptoms referred for diagnosis and treatment of hepatic failure subsequently proved to have cardiomyopathy as the cause of their hepatic decompensation. Except for fatigue and edema, symptoms of congestive heart failure were absent and no history of dyspnea, orthopnea, or paroxysmal nocturnal dyspnea could be elicited. Hepatomegaly was present in both patients, but neck venous distension and hypotension were not apparent, and both patients were able to lie flat. The diagnosis of cardiomyopathy was made by echocardiogram showing global hypokinesis and low ejection fractions; right atrial pressures were markedly increased. Liver biopsies demonstrated centrilobular necrosis and congestion. Treatment for heart failure led to a prompt response in both patients with rapid return of all hepatic parameters toward normal. Paradoxically, our patients had striking evidence of hepatic failure and a notable absence of symptoms and signs of congestive heart failure. An awareness of this unique presentation may avoid prolonged evaluations in such critically ill patients.

This is a case report of a pheochromocytoma which developed in a 67-year-old man. The patient presented himself with a productive cough and orthopnea, both of which were subsequently proved to be due to hypertensive heart failure. The diagnosis of a pheochromocytoma originating from the left adrenal gland was established endocrinologically and roentgenologically. Transperitoneal adrenalectomy was undertaken, and a tumor weighing 300 g was obtained. Histopathologically, the tumor was composed of two elements: cells with profuse cytoplasma having chromaffin-positive granules, and other cells consisting of spindle cells with mitosis. Surgical exploration could not identify another tumor or metastasis, and his blood pressure returned to normal, with normal catecholamine levels, after surgery. This is the first reported case of an elderly person with a pheochromocytoma complicated by congestive heart failure and renal insufficiency preoperatively; however, it was controlled well, and he underwent surgery successfully. This case constitutes the 64th report on a pheochromocytoma in persons over 60 years of age in the Japanese literature.

In rare instances, chronic alcoholism leads to the congestive heart failure which is characteristic of alcoholic beriberi with edema. The affected patients is usually a young man with longstanding alcoholic intoxication and often with neurologic features. Onset is often sudden, with dyspnea on exertion, orthopnea, and palpitations. The clinical sings of cardiac failure are unequivocal. Roentgenography shows cardiomegaly mainly due to enlargement of the right cavities and of the pulmonary artery. ECG shows sinus tachycardia and abnormal repolarisation in the precordium. The cardiac output and the cardiac index are increased, as well as the coronary output. Pyruvic acid levels exceed 15 mg/l, the provoked hyperpyruvicemia test is abnormal, thiamine levels are low, and the tryptophane test is normal. The course is variable. Cardiac beriberi progresses by exacerbation and remissions. Prognosis is poor, with a risk of sudden death. However, with adequate treatment combining rest, a low sodium diet, alcohol withdrawal, diuretics, and vitamin B1 (IV) recovery occurs. Our two observations clearly fit this description.

Ninety-two patients with heart failure refractory to digitalis and diuretic therapy had captopril (n = 50) or placebo (n = 42) added to their therapeutic regimen in a randomized, double-blind trial. During a 2 week dosage titration period, one captopril-treated patient died of an intracerebral hemorrhage. Over the remaining 10 week evaluation period, 1 captopril-treated patient (2%) was excluded from the study because of treatment failure as compared with 12 discontinuations (4 deaths and 8 failures [29%]) among the placebo group (p less than 0.001). Eighty percent of patients in the captopril group exhibited some degree of clinical improvement, whereas only 27% in the placebo group did so (p less than 0.001). The therapeutic advantage of captopril over placebo was evidenced by a mean improvement of 0.52 (2.8 +/- 0.1 to 2.3 +/- 0.1) in the New York Heart Association functional class value as compared with 0.03 (2.9 +/- 0.1 to 2.8 +/- 0.1) with placebo (p less than 0.0001). There was a 24% mean increase in exercise tolerance with captopril (495 +/- 22 to 614 +/- 27 seconds) as compared with 0.4% with placebo (480 +/- 28 to 483 +/- 43 seconds) (p less than 0.01); the captopril group had an increase in the ejection fraction from a mean baseline value of 0.19 +/- 0.02 to 0.22 +2- 0.02 as compared with 0.19 +/- 0.02 to 0.18 +/- 0.002 (p less than 0.05) in the placebo group. A cohort analysis revealed that improvement in exercise tolerance with captopril was gradual and progressive throughout the 12 weeks. Improvement in specific symptoms of heart failure, that is, dyspnea, fatigue and orthopnea, and the reduction of edema also were greater in the captopril-treated patients (p less than 0.05 to p less than 0.001). Captopril therapy was well tolerated, although symptomatic hypotension after the first dose caused withdrawal of three patients (3%) from the study. It was concluded that captopril is an effective adjunctive treatment to digitalis and diuretic drugs for patients with refractory heart failure.
