This study presents the determination of reference values for MMG in order to validate this novel technique in gastric emptying measurements.

Improvement of diastolic function after regression of left ventricular hypertrophy.

Objective: To evaluate the diastolic function after regression of left ventricular hypertrophy, in mild to moderate hypertension treated with angiotensin converting enzyme(ACE) inhibitor and, if necessary, with a diuretic.

Methods: Ninety-eight hypertensive patients with left ventricular hypertrophy (LVH) and abnormal left ventricle diastolic function indexes received captopril (Capotena) 50 to 200 mg/day plus chlortalidone during 12 months to reach blood pressure control, defined as a diastolic blood pressure < or =90 and systolic blood pressure < or =140 mm Hg. Left ventricular (LV) mass index was calculated by M mode and two-dimensional echocardiography, and left ventricular diastolic function was assessed by transmitral pulsed Doppler ultrasound every 3 months.

[Cardiovascular magnetic resonance evaluation of left-to-right shunts due to cardiac septal defects in patients with pulmonary arterial hypertension].

Introduction And Objectives: As cardiac septal defects are frequently associated with pulmonary arterial hypertension, hemodynamic assessment is essential before deciding on surgery. The aim of this study was to evaluate the use of cardiovascular magnetic resonance imaging for assessing cardiac shunts and for quantifying pulmonary artery systolic pressure in patients with cardiac septal defects.

Methods: This cross-sectional study involved patients with cardiac septal defects and clinically suspected severe pulmonary arterial hypertension who had an indication for cardiac catheterization and in whom magnetic resonance imaging was not contraindicated.

Magnetogastrography (MGG) reproducibility assessments of gastric emptying on healthy subjects.

The aim of this study was to evaluate the half-time gastric emptying reproducibility measured by magnetogastrography (MGG). Seven healthy subjects were subjected to a magnetic pulse of 32 mT for 17 ms, seven times in 90 min. The procedure was repeated one and two weeks later.

[Pentalogy of Cantrell. A case report].

Ectopia cordis is an extremely rare cardiac anomaly. The heart is localized partially or totally outside the thorax cavity. This anomaly occurs as an isolated defect or combined with others midline defects.

Intraluminal aortoplasty vs. surgical aortic resection in congenital aortic coarctation. A clinical random study in pediatric patients.

Background: Our objective was to compare results of two therapeutic modalities to treat congenital aortic coarctation: intraluminal aortoplasty without endoluminal stent installation (patients in group A) vs. surgical aortic resection (patients in group B). Trans-coarctation gradient pressure was evaluated prior to and immediately after treatment.

[Multiple coronary arteriovenous fistulae. Hazard or predetermination?].

Objective: The authors present the clinical cases of three adult patients (49, 53 and 61 year-old), with rheumatic cardiac valvulopathy, and bilateral coronary arteriovenous fistulae draining in the main pulmonary artery. Based on documental investigation, the authors speculate about the predeterminate origin of coronary arteriovenous fistulae.

Discussion: At first glance, it seems obvious that congenital cardiopathies occur at random, i.

Angiographic concurrence of coronary artery disease and aortoiliac lesions.

The importance of recognizing the association between aortoiliac disease and coronary artery disease includes the following: (1) Long-term morbidity is higher and survival ratio poorer in patients with coronary heart disease compared with isolated lower extremity revascularization surgery. (2) Coronary artery bypass grafting is a relatively high-risk procedure in patients with severe vascular disease. (3) There is the prospect that the patient will eventually face simultaneous coronary artery and vascular surgery, or coronary artery angioplasty previous to aortoiliac surgery.

[Stenting and redilatation of the ductus arteriosus in univentricular heart with pulmonary atresia. A case report].

Complex congenital heart disease with pulmonary atresia is ductus arteriosus-dependent. Two palliative treatments have been available for years: a systemic pulmonary shunt and prostaglandin E1 infusion. Recently, interventional cardiology has offered a new procedure for these patients: stenting of the patent arterial duct.

Three pregnant women with 5 +/- 1.7 weeks of pregnancy and mitral stenosis are described. Their valve area were < 1.

[Low-molecular-weight heparin in unstable angina pectoris].

We studied the therapeutic effect of standard heparin (HS) compared with low-molecular-weight (HBPM) in two homogeneous groups of 14 patients heparin selected at random, with clinical history and electrocardiographic signs of unstable angina pectoris. Patients received the conventional treatment with platelets' inhibitors, nitrates, adrenergic beta-blockers or calcium antagonists. Both heparins, separately, showed statistical therapeutic effect on the symptoms and signs of unstable angina pectoris.

[Percutaneous mitral commissurotomy in patients with mitral valve stenosis and thrombosis of the left atrium].

Unlabelled: Mitral percutaneous valvotomy (MPV) is an effective therapeutic alternative in the treatment of patients with mitral stenosis (MS) and thrombus in the left atrium have been an absolute contraindication to this procedure. The aim of our study is to evaluate the safety of MPV in patients with MS and thrombus in the appendix of the left atrium (ALA). Between September 1996 and April 1997, we performed ten procedures of MPV with Inoue's technique in patients with MS and thrombus in ALA.

[Acute myocardial infarction with normal coronary arteries as initial manifestation of polyarteritis nodosa. A case report].

A thirty four-year-old-white man in good health developed an acute anterior wall myocardial infarction (AMI), Killip II with normal coronary arteries. No thrombolytic therapy was given. Selective angiography revealed multiple aneurysms in mesenteric and renal arteries.

[Effectiveness of anticoagulant oral treatment in patients with thrombus in left ventricle after acute myocardial infarction].

Left ventricular mural thrombi (LVMT) is a complication of acute myocardial infarction (AMI), that may produce peripheral embolism which could be fatal. In order to establish an adequate time of oral anticoagulant (OA) therapy, we undertook a prospective study that included 45 patients with AMI and left ventricular thrombi detected by echocardiographic study, in the first 5 to 10 days postinfarction, the study was repeated, in 3 and 6 months. Treatment with oral anticoagulant was initiated at the point of the detection of thrombi maintaining an INR of 1.
