Coronary sinus defects refer to interatrial communications that lie out of the confines of the atrial septum and leads from left to right shunt through the ostium of the coronary sinus. When associated with persistent left superior vena cava (PLSVC), mild systemic desaturation may occur depending on the extent of unroofing of the coronary sinus. Isolated defects without PLSVC are rare. Three-dimensional echocardiographic and surgical images are presented.

Aims: Phosphodiesterase 2A, a cAMP-hydrolysing enzyme, is essential for mouse development, however the cause of Pde2A knockout embryonic lethality is unknown. To understand if Pde2A plays a role in cardiac development, hearts of Pde2A deficient embryos were analysed at different stage of development. Methods and Results: At the stage of four chambers, Pde2A deficient hearts were enlarged compared to the hearts of Pde2A heterozygous and wild-type. Pde2A knockout embryos revealed cardiac defects such as absence of atrial trabeculation, interventricular septum defects, hypertrabeculation and thinning of the myocardial wall and in rare cases they had overriding aorta and valves defects...

We report a newborn female baby who presented at 6 hours of age with cyanosis without any signs of respiratory distress. Cardiovascular and systemic examination was unremarkable apart from cyanosis (saturation 75%). An echocardiogram showed multiple echogenic and homogeneous masses in the interventricular septum, one of which was big and protruding through the tricuspid valve causing right ventricular inflow obstruction. There was a small atrial septal defect (ASD) shunting right to left and patent ductus arteriosus (PDA) shunting left to right...

INTRODUCTION: Transcatheter closure has become the treatment of choice for secundum atrial septal defects (ASD II), but particularly in small children, there is concern regarding procedure-related complications. CASE DESCRIPTION: We report on a 10-month-old infant, body weight of 6.4 kg, with a large ASD who was referred for failure to thrive and dyspnea on exertion. Echocardiography showed two neighboring ASDs centrally located within an atrial septum with a length of 27 mm resulting in significant left-to-right shunting...

Atrial septal aneurysm (ASA) is a localized deformity of the interatrial septum, which protrudes into the right and/or left atrium. ASA with defects is a source of cardiac embolism. Although transcatheter closure is now a common procedure, it is still challenging in patients with complicated ASA. We describe a case of giant atypical multiperforated ASA with irregular mobility, which showed a rare "aneurysm in aneurysm" structure. Real-time three-dimensional transesophageal echocardiography showed vivid images, which clearly demonstrated these irregular shaped defects mimicking the atriotomy view, and played a crucial role in guiding the transcatheter closure...

Alongside the mitral repair or replacement, a considerable number of concomitant procedures can be performed with the minimally invasive mitral valve surgical approach. Some of these concomitant procedures comprise the tricuspid valve repair or replacement, left atrial appendage (LAA) exclusion, Interatrial septum defects correction and atrial fibrillation (AF) ablation.

BACKGROUND: Right ventricular (RV) dysfunction may be caused by either pressure or volume overload. RV function is conventionally assessed with echocardiography using tricuspid annular plane systolic excursion (TAPSE), RV fractional area change (RVFAC), tricuspid lateral annular systolic velocity (S') and RV index of myocardial performance (RIMP). The purpose of this study was to evaluate whether RV global longitudinal strain (RVGLS) and RV-free wall strain (RV-free) could add additional information to differentiate these two causes of RV overload...

We describe an unusual case of partial atrioventricular septal defect with malalignment of the septum primum to the left atrium with respect to the ventricular septum, committing the tricuspid valve to both ventricles (double-outlet right atrium). Abnormal attachment of the septum primum to the lateral aspect of mitral annulus resulted in left atrial outflow obstruction. The patient underwent successful surgical correction.

Percutaneous closure is the treatment of choice for secundum-type atrial septal defects (ASD). Balloon sizing (BS) has been the method of choice for deciding on device size. Improved 2D- and 3D-transesophageal echocardiographic (TEE) imaging challenged the necessity of BS. Balloon sizing was performed with two additional techniques to measure the stretched dimension of the ASD. The 1st method uses a stiff guide wire which stretches the ASD and 2D TEE. The second technique uses 3D TEE. Two hundred and thirty-six patients with minimum 1-year follow-up were enrolled...

Transcatheter closure of atrial septal defects and patent foramen ovale has become increasingly common with advances in device and imaging technology. The percutaneous approach is now the preferred method of closure when anatomically suitable. Two-dimensional and 3-dimensional echocardiography determines anatomic suitability by characterizing the interatrial defect and its surrounding structures, and is critical for intraprocedural guidance and postprocedure follow-up. This article provides an overview of interatrial anatomy as it pertains to interventional considerations and discusses the transthoracic, transesophageal, and intracardiac echocardiographic modalities used for periprocedural and intraprocedural imaging of the interatrial septum...

Fetal cardiac intervention (FCI) is a relatively new and continually evolving field, and, for select cardiac defects, offers the potential to alter the progression of the disease and improve outcomes. It is a procedure that requires a collaborative effort between maternal-fetal medicine, interventional cardiology and fetal echo/ultrasound specialists, as well as fetal and maternal anesthesiologists, nursing specialists, and social workers. This article reviews the most recently reported data and advances in FCI...
