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.

Applicability of the Leiden Convention and the Lipton Classification in Patients with a Single Coronary Artery in the Setting of Congenital Heart Disease.

In single coronary artery (SCA) anatomy, all coronary tributaries arise from a single ostium, providing perfusion to the entire myocardium. Coronary classification systems can facilitate the description of SCA anatomy. Evaluation of the applicability of Lipton classification and the Leiden Convention coronary coding system in SCA.

[Evaluation of cardiac tumors by multidetector computed tomography and magnetic resonance imaging].

Cardiac tumors, are a rare pathology (0.002-0.3%) in all age groups, however, they have a clinic importance, due the affected organ.

Dual-source 256-MDCT for diagnosis of anomalous pulmonary venous drainage in pediatric population.

Objective: The purpose of this study is to describe the MDCT findings of anomalous pulmonary venous drainage (APVD) in a pediatric population using a 256-MDCT dual-source scanner with a high-pitch protocol.

Conclusion: MDCT is a fast and noninvasive technique that allows detailed and comprehensive visualization of APVD characteristics in a pediatric population. High-pitch acquisitions with scanners using a high volume of coverage permit low radiation doses and are an accurate modality for assessing these patients.

Left ventricular noncompaction: a proposal of new diagnostic criteria by multidetector computed tomography.

Background: Left ventricular noncompaction (LVNC) is a cardiomyopathy characterized by a noncompacted myocardial layer in the left ventricle, primarily diagnosed by echocardiographic and magnetic resonance criteria. Multidetector computed tomography (MDCT) is an imaging method that has been increasingly used in cardiac evaluation. However, tomographic criteria to diagnose LVNC have not been determined.

Cor triatriatum sinister versus bowed septum primum in an infant with total anomalous pulmonary venous connection: a difficult imaging distinction.

In cor triatriatum sinister, a membrane divides the left atrium into a posterior chamber that receives the pulmonary veins and an anterior chamber that communicates with the mitral valve. With right-side chamber overload, the septum primum can separate from the muscular septum and bow toward the left atrial cavity, leading to a thin membrane within the left atrium and imaging findings that may mimic cor triatriatum. We report the multidetector CT findings of a 3-month-old infant with a supracardiac total anomalous pulmonary venous connection with a bowed septum primum.
