Left atrial calcification in a hemodialysis patient with cor triatriatum.

Myocardial calcification is a rare manifestation of abnormal calcium metabolism seen in some patients with chronic renal failure. This report describes the transesophageal echocardiographic and spiral computed tomography (CT) findings in a young hemodialysis female with severe secondary hyperparathyroidism. These findings included calcification of the multiperforated membrane of a cor triatriatum and the wall of the left atrium.

Double-chamber right ventricle in a 63-year-old woman.

Double-chamber right ventricle (DCRV) is a rare congenital heart disease consisting in right ventricular obstruction due to one or several anomalous muscle bundles that divide the right ventricle into two chambers. Because of the rarity of this anomaly in adults, we present the case of a 63-year-old woman suffering from this heart disease, being on the other hand, one of the few cases described in the literature in such an old patient.

Myocardial infarction with thrombus formation during prolonged intense exercise.

We present the case of a healthy young white man, who suddenly complained of strong pain in the lower extremities while he was cycling. An emergency bilateral femoral thromboembolectomy was carried out and thrombotic material was obtained. A two-dimensional echocardiogram showed a mobile mass adhered to the apex. Pathological study of the mass revealed a small myocardial infarction with thrombus.

[Infectious endocarditis of the native valve: its epidemiological profile and an analysis of its mortality between the years 1984 and 1993].

BACKGROUND: The description of the epidemiologic profile and analysis of the mortality of infectious endocarditis (IE) observed from 1984-1993. METHODS: One hundred thirty episodes of IE in a native valve (30 in drug addicts [IVDA] and 20 cases of nosocomial acquisition) were analyzed with right/left/bilateral localization (42/84/4, respectively), infection of the mitral/aortic/tricuspid valve (52/47/34, respectively) and the etiology was determined as Staphylococcus aureus in 52 cases, 41 Streptococcus, 13 negative coagulase Staphylococcus, and 11 Enterococcus. High risk IE were identified by uni and multivariate analysis (MVA). RESULTS: The incidence of IE ranged from 0.36 and 0.70 cases x 1.000 admitted adults/year (mean: 0.50). Transthoracic echocardiography detected bacterial vegetations in 67% of the cases with the validity to predict the development of embolisms being 55%. MVA showed the embolic episodes (present in 45% of the IE) to be associated with the IVDA patients and prolonged fever. The latter complication, being defined as > or = 10 days of fever under appropriate treatment, was observed in 32% of the cases and was due to mild (n = 15) and severe causes (n = 27). Postembolic septic complications were associated to fever with MVA. Twenty three patients died (18%), 2 IVDA and 5 nosocomial IE, mainly due to heart failure (n = 13). The independent risk factor predictors for death (p < 0.05) were: age > or = 60 years (mortality 34%), cerebral embolisms (55%), severe heart failure (37%), and the exclusion of the patient as a candidate for surgery (73%). To the contrary, right IE (mortality 0%) and cardiac surgery (5%) favoured survival. CONCLUSIONS: To improve the prognosis of infectious endocarditis in high risk patients more opportune cardiac surgery accepting greater risks should be performed.

[The long-term evolution of patients with senile aortic stenosis undergoing percutaneous valve dilatation].

The long-term follow-up of 35 patients with mean age of 74.3 +/- 8 years (64-86) who underwent percutaneous aortic valvuloplasty (PAV) is presented. The mean duration of the follow-up study was 33 months (range 1-48). Global mortality was 42% (14 patients) and was related to post-PAV aortic valvular area (47% mortality in less than 0.7 cm2 area group vs 28% in greater than or equal to 0.7 cm2 group) and left ventricular ejection fraction (67% in EF less than 35% group vs 35% in EF greater than or equal to 35% group). The actuarial probability of remaining alive and free of symptoms and of cardiac surgery or new PAV was 57, 41, 33, and 20% at 1, 2, 3 and 4 years. After PAV clinical improvement was obtained in most of the patients (68%), but only 42% of those with successful dilatation remain asymptomatic after a 24 months period (85 +/- 28 mmHg, p = NS). Transvalvular gradient studied by Doppler decreased immediately after PAV (92.8 +/- 26 mmHg vs 51 +/- 16 mmHg, p less than 0.001), but returned to baseline values after 12 months. These results show that PAV yields a clinical improvement in most of the patients, but this improvement is transitory, does not modify the natural history of the disease and has a high degree of restenosis. Thus, its use must be limited to a reduced group of patients who are not candidates for cardiac surgery.
