cardiac ct in mixed type atrial septum defects

Atrial septum fat deposition and atrial anatomy assessed by cardiac magnetic resonance: relationship to atrial electrophysiology

Methods 44 consecutive patients with normal left ventricular ejection fraction (LVEF> 35%), age<70 years old, were enrolled in a research study exploring the underlying myocardial substrate of ECG findings. The presence of interatrial fat was assessed with a complete CMR study including Dark-blood DIR-prepared Fat-Water-separated sequence3 in the horizontal longitudinal axis (4 chamber view). T...

Atrial pressure-flow dynamics in atrial septal defects (secundum type).

Imaging of adult atrial septal defects with CT angiography.

ATRIAL SEPTAL DEFECTS (ASD) ACCOUNT FOR 5% TO 10% OF ALL CASES OF CONGENITAL heart disease and as many as 30% of cases of congenital heart disease presenting in adulthood. These defects make up a spectrum of interesting and distinct entities. The ostium secundum ASD accounts for 70% to 80% of all adult ASDs. Other less common forms of adult ASDs include ostium primum ASD (15% of ASDs), sinus ve...

Translocation of the atrial septum.

[Lipomatous hypertrophy in the atrial septum].

Subcostal 4-chamber view of transthoracic echocardiography revealed abnormal thickening of atrial septum (arrow) in a 43-year-old Japanese woman with frequent atrial premature beats (A). MRI was obtained by the ECG-gated spin-echo technique. T1-weighted image of the heart demonstrated large fatty deposits (arrow) in the atrial septum, which have been referred to as lipomatous hypertrophy of the...

Diastolic Function in Paced Children with Cardiac Defects: Septum vs Apex

In children with structural congenital heart disease (CHD), the effects of chronic ventricular pacing on diastolic function are not well known. On the other hand, the beneficial effect of septal pacing over apical pacing is still controversial.The aim of this study was to evaluate the influence of different right ventricular (RV) pacing site on left ventricular (LV) diastolic function in childr...
