Echocardiographic findings in patent ductus arteriosus-associated infective endarteritis.

Background: Infectious endarteritis associated with patent ductus arteriosus (PDA-IE) is an uncommon complication in the era of antibiotics. However, it implies a clinical challenge in patients with a fever of undetermined origin; Two-dimensional transthoracic echocardiography (TTE) performs a fundamental role in diagnosis and follow-up.

Methods: A retrospective analysis was then made of the data of all patients admitted at our center with PDA-IE within 15 years, and a review of the literature regarding diagnosis, TTE findings, and treatment was performed.

[Cor Triatriatum Dexter: an unusual cause of neonatal cyanosis].

We present the case of a term newborn, with no significant perinatal history, who was taken to the emergency room at 18 days old for intermittent episodes of cyanosis, with no signs of respiratory distress, oxygensaturation of 85%, arterial gases with moderate hypoxemia, and chest X-ray.

Subclinical cardiac alterations detected by echocardiography in Mexican schoolchildren with overweight and obesity.

Objective: The purpose of this study was to evaluate early changes in myocardial function in overweight and obese children without hypertension.

Methods: This was a cross-sectional study involving 150 participants of both sexes between 6 and 15 years old. Anthropometric and biochemical evaluations were performed.

Left ventricular longitudinal strain measured by speckle tracking as a predictor of the decrease in left ventricular deformation in children with congenital stenosis of the aorta or coarctation of the aorta.

Children born with a left ventricular outflow tract obstruction (LVOTO) can present with symptoms of left ventricular (LV) failure while ejection fraction (EF) is normal. A more sensitive parameter of systolic function might be obtained with speckle tracking echocardiography, which describes ventricular longitudinal deformation in strain values. It is presumed that despite a normal or only slight decrease in ejection fraction, patients with a LVOTO demonstrate aberrations in the longitudinal deformation of the left ventricle.

[Anatomic spectrum between complete and partial atrioventricular septal defect. Two and three-dimensional echocardiography approach].

Introduction: It has been postulated that there is a morphogenetic relation between the atrioventricular septal defect (AVSD) type A of Rastelli and the type of two separated orifices, this so called partial forms, existent between both types a spectrum of anatomical forms in which interchordal spaces determinate the ventricular septal defects (VSD) size to forms in which the VSD is closed by fusion of the left septal valves to the crest of ventricular septum.

Methods: We present five patients which illustrates the variability of the atrioventricular defect by means of two dimensional and three-dimensional echocardiography. In each case was made a transesophagic echocardiogram using three-dimensional reconstruction with an Echo-Scan system (4.

[Acute right atrial and ventricular infarction].

Acute coronary syndromes involving the right side of the heart are associated with increased mortality, a complex clinical course, and lengthy hospitalization, as well as with frequent mechanical and electrical complications. It is important that the signs and symptoms associated with the spread of ischemic disease to the right heart chambers are recognized so that the patient can be given appropriate treatment, which can improve short-term and long-term prognosis. The purpose of this review was to summarize key aspects of the diagnosis, prognosis and treatment of this condition.

[Pulmonary hypertension in children with Down's syndrome and congenital heart disease. Is it really more severe?].

Objective: To compare the hemodynamic state, the severity and reversibility of pulmonary arterial hypertension (PAH) in patients with Down's syndrome and congenital heart disease (CHD) with respect to those without chromosomal pathologies.

Material And Methods: 30 patients with congenital heart disease and left to right shunt were studied, corroborated by echocardiography; 16 patients had Down's syndrome and CHD and the control group was constituted by 14 patients without chromosomal abnormalities and with CHD. The age was R = 4.

[Recurrent myxoma. Bi and three-dimensional echocardiography approach].

The case of a 16-years old female patient with left atrial myxoma and cerebral embolism is reported. She was subjected to surgical excision of the mass. At 40 months of follow-up she initiates with dyspnea and an aortic murmur is detected.

[Double symmetrical aortic arch. Case report].

We report a six-month-old patient with a double symmetrical aortic arch with tracheal and esophageal obstructive symptoms, who was treated surgically. The diagnostic images consisting of esophagogram, echocardiography and angiography were correlated with an anatomical specimen; the usefulness of the echocardiogram as an initial test is emphasized.

[Unruptured sinus of Valsalva aneurysm. Bi and three-dimensional echocardiography approach].

Aneurysm of the sinus of Valsalva is a rare anomaly that can be congenital or acquire. The most common among the acquire is aortic endocarditis. At the present time echocardiography has be come the election diagnostic method.

[Treatment of patent ductus arteriosus. Comparison of costs between surgical and trans-catheter closures in a public institution].

Unlabelled: The costs of transcatheter closure of patent ductus arteriosus in relation to the surgical closure still a controvertial issue in our hospitals. The aim of the study was compared the costs of both treatments.

Methods: We included 57 patients treated with transcatheter occlusion and 26 underwent surgery.

[Perioperative transesophageal echocardiography in congenital cardiopathies].

The usefulness of the perioperative transesophagical echocardiography has been well established in the treatment of patients with congenital heart disease. This modality provides additional anatomical information to transthoracic images and the opportunity of confirming the diagnoses, and according to the findings, deciding if surgical plan changes are require or if a surgical review is needed before leaving the operating room. The perioperative and post-repair examinations are indicated when operations are performed on cardiac defects in which there are echocardiogram residual abnormalities than can be anticipated such as outflow tract obstructions, valve regurgitation or stenosis or residual communications, as a rule in most congenital heart defects surgeries under cardiopulmonary bypass.

[Left ventricular outflow tract obstruction in transposition of the great arteries. Correlation between anatomic and echocardiographic findings].

Introduction And Objectives: Left ventricle outflow tract obstructions in transposition of the great arteries are frequent. We report the correlations between two-dimensional echocardiographic and autopsy findings to draw attention to the usefulness of this diagnostic method in the preoperative evaluation of these anomalies.

Material And Methods: Of 73 hearts with transposition of great arteries, 26 specimens (38%) with different types of left ventricular outflow tract obstruction were selected to establish the relationship between an anatomical substrate of obstruction and echocardiographic findings in equivalent hearts.

[Aortic valve complications associated with subarterial infundibular ventricular septal defect. Echocardiograpic follow-up].

Introduction And Objectives: Interventricular fibromuscular septal defects of the outlet tract are subarterial infundibular ventricular septal defects (VSDs). This anatomical situation predisposes to aortic cusp prolapse (AoP) and/or regurgitation (AoR).

Methods: In order to determinate the frequency of VSDs and the presence or development of aortic valve alterations detected by two-dimensional echocardiography, we studied 35 patients with VSDs.

[Role of the echocardiogram in adults with congenital cardiopathy].

Advances in cardiac surgery, intensive care and non-invasive diagnostic methods in congenital heart diseases have allowed ford a high percentage of these patients to arrive to adult hood. Initial presentation of this type of anomalies in adult life is now uncommon. Most of these lesions are not arribe complex and easily acknowledged, but occasionally complex defects that represent a challenge for the diagnostic and treatment options.
