Primary Arterial Switch Operation for Late Presentation of Transposition of the Great Arteries With Intact Ventricular Septum.

Transposition of the great arteries (TGA) with intact ventricular septum (IVS) are subject to neonatal arterial switch operation (ASO) to avoid deconditioning of the left ventricle (LV). Often an early repair is not feasible in developing countries where late referral is frequent. We aim to explore ASO outcomes in late TGA-IVS and compare "unfavorable candidates" (LV myocardial mass <35gr/m unfavorable geometry.

A Misdiagnosed Case of Double Outlet Right Atrium Associated With Hypoplastic Right Ventricle.

Double outlet right atrium (DORA) is a rare congenital heart disease in which the right atrium opens into both ventricles. The reduced leftward motion of the interventricular septum causes a malalignment between the atrial and the ventricular septum at the cardiac crux, which is the pathognomonic feature of this heart defect. We describe a case of significant exertional desaturation in an adult patient who was diagnosed with DORA, restrictive right ventricle, and anomalous tricuspid valve.

How to deal with atrial septal defect closure from right internal jugular vein: Role of venous-arterial circuit for sizing and over-the-wire device implantation.

Secundum atrial septum defect (ASD) is the most common congenital heart disease. It is usually treated by a transcatheter approach using a femoral venous access. In case of bilateral femoral vein occlusion, the internal jugular venous approach for ASD closure is an option, in particular in cases where ASD balloon occlusion test and sizing is needed.

Goose-neck snare-assisted transcatheter ASD closure: A safety procedure for large and complex ASDs.

Objective: To report on a new technique that increases the safety of percutaneous atrial septal defect (ASD) closure using a goose-neck snare system.

Background: ASD transcatheter closure is a widespread procedure. However, in some cases, ASDs may be large and with soft rims.

Patent ductus arteriosus balloon sizing: A new technique to evaluate the size in complex cases.

Patent ductus arteriosus (PDA) transcatheter closure is a widespread procedure. However in some cases PDA measurements may be unclear and choice of the proper device could be quite difficult. This may happen in large PDA and in particular in adults.

[Anomalous origin of the coronary arteries: five case reports and review of the literature].

Background: Although individual patient outcomes are highly variable, coronary artery anomalies may be associated with sudden cardiac death or acute coronary syndrome.

Methods: We report 5 cases of anomalous origin of coronary arteries: a single coronary artery originating from the right sinus of Valsalva, a case of isolated anomalous right coronary artery originating separately from the left sinus of Valsalva, a case of right coronary artery originating between the right and left sinus of Valsalva, a case of anomalous left circumflex artery originating from the right sinus of Valsalva, and a case of anomalous left anterior descending coronary artery originating from the right sinus of Valsalva.

Results: Although in one case the right coronary artery runned between the aorta and the right pulmonary artery, no significant alterations due to coronary artery compression or atheromatous lesions at the anomalous coronary ostia were observed.
