[Tolerance to valsartan in office practice in 3,197 hypertensive patients (the VALSE study)].

Valsartan, an angiotensin II antagonist with a potent and highly selective effect on AT1 receptors, has been found effective and safe in several randomized, controlled studies versus a placebo, other antihypertensive agents, or other angiotensin II antagonists. An eight-week, open-label, multicenter, prospective, pragmatic, phase IV trial was conducted by office-based cardiologists to evaluate the clinical safety and efficacy of valsartan 80 mg in everyday practice. The efficacy analysis included 3084 patients given valsartan alone for four weeks then, during the next four weeks, either valsartan alone or, if the diastolic blood pressure was still > or = 90 mmHg, valsartan in combination with another antihypertensive agent. The valsartan dosage was 80 mg/day. On day 28, 64% of patients were controlled and 78% were responders. The safety analysis included 3,108 patients. Of the 239 medical adverse events ascribed by the investigators to the study treatment, 72 led to premature study discontinuation. This figure translated into a 2.68% rate among treated patients, which is similar to the 2.3% rate recorded during the placebo-controlled trials performed as part of the valsartan clinical development program. These results confirm the outstanding safety profile of valsartan.

Role of tricuspid regurgitation and left ventricular damage in the treatment of right ventricular infarction-induced low cardiac output syndrome.

To evaluate, in right ventricular (RV) myocardial infarction, the role of tricuspid regurgitation (TR) and left ventricular (LV) damage and the response to treatment of low cardiac output, 20 patients were prospectively studied. Volume infusion increased cardiac output only slightly (11%, p less than 0.001), despite a dramatic increase in ventricular filling pressures. Dobutamine (4 micrograms.kg-1.min-1) markedly increased cardiac output (24%, p less than 0.001) with a decrease in ventricular filling pressures. In the 5 patients with TR, dobutamine only modestly increased cardiac output (9 vs 26%, p less than 0.001), while stroke index and LV end-diastolic dimensions decreased in comparison (-5 vs 33% and -6 vs 9%, respectively, p less than 0.001). In the absence of TR (n = 15), there was no significant difference in response to volume expansion between patients with normal (n = 7) and depressed LV ejection fraction (n = 8). In contrast, dobutamine, in patients with depressed LV function, induced a greater increase in cardiac output (38 vs 17%, p less than 0.01) and RV ejection fraction (36 vs 12%, p less than 0.05). All patients with RV infarction-induced low cardiac output responded only modestly to volume loading. Dobutamine is particularly efficacious in patients without TR who have depressed LV function by improving RV function and, consequently, LV preload. In the 5 patients with TR, increasing RV contractility failed to improve the forward stroke volume by increasing the regurgitant fraction.

[Copious pericardial and pleural effusion of hypothyroid origin. Report of a case and review of the literature].

The authors report the case of a female of 57 years presenting hypothyroidism with pericardial tamponade followed by development of copious pleural extravasation. The present observation and those reported in the literature are used to evoke the characteristics of copious pericardial and pleural extravasation during hypothyroidism. The authors emphasize the importance of cardiac echography during myxedema. A few exceptional observations aside, extravasation is reduced by supplementary hormone therapy.

[Cardiac hydatidosis].

Cardiac localizations in hydatid disease are uncommon and often latent. A mass at the apex of the heart was discovered in a 42-year-old patient who presented with abnormal EKG repolarization. This mass was anechoic. Coronography demonstrated an avascular lesion with displaced coronary arteries. A hydatid cyst was suspected. No other visceral localizations of hydatid disease were detected. The patient refused surgery and was seen two years later with acute pericarditis and rapidly developing cardiac tamponade. A very large amount of pericardial fluid and a single hydatid cyst were discovered upon surgery. The cyst was aspirated and sterilized and the protruding cyst wall was resected. A severe postpericardotomy syndrome and positivation of hydatid disease serological tests occurred during the postoperative course. The patient was then given flubendazole. Prompt recovery occurred and the patient is still doing well under therapy two years later. In hydatid disease, an isolated cardiac localization is uncommon and often latent and may be revealed by complications. Prompt diagnosis should be made by echocardiography.
