Four-dimensional endocardial surface imaging with dynamic virtual reality rendering: a technical note.

Open heart surgery requires a proper understanding of the endocardial surface of the heart and vascular structures. While modern four-dimensional (4D) imaging enables excellent dynamic visualization of the blood pool, endocardial surface anatomy has not routinely been assessed. 4D image data were post-processed using commercially available virtual reality (VR) software.

Multidetector Computed Tomography Assessment of Anatomical Ventricular Tachycardia Isthmuses in Repaired Tetralogy of Fallot.

Background: Tetralogy of Fallot (TOF) is associated with risk for sustained monomorphic ventricular tachycardia (VT). Preemptive electrophysiology study before transcatheter pulmonary valve placement is increasing, but the value of MDCT for anatomical VT isthmus assessment is unknown.

Objectives: The purpose of this study was to determine the impact of multidetector computed tomography (MDCT) in the evaluation of sustained monomorphic VT for repaired TOF.

Apical muscular ventricular septal defect closure via hybrid approach using a right ventricular stay suture.

Transcatheter closure of large apical muscular ventricular septal defects (VSDs) can be performed via transfemoral or hybrid approach. A very large apical muscular VSD was closed via a hybrid approach. A strategy for deployment of a right ventricular stay suture was utilized to minimize the risk of device embolization without the use of bypass and without externalization of a portion of the device.

Ten-year outcomes of transcaval cardiac puncture for catheter ablation after extracardiac Fontan surgery.

Background: Although they are at lower risk, patients with previous extracardiac conduit (EC) Fontan still may require catheter ablation for supraventricular arrhythmia.

Objective: The purpose of this study was to determine the optimal approach to pulmonary venous atrium (PVA) access after EC Fontan operation.

Methods: All electrophysiological procedures requiring PVA over a 10-year period at the UCLA Medical Center were reviewed.

Growth and weight gain of prepubertal children after cardiac transplantation.

This study evaluated changes in growth parameters after pediatric heart transplantation and identified factors associated with the changes after pediatric heart transplantation (OHT). We retrospectively evaluated the somatic growth of 46 children <11 yr of age who underwent OHT for changes in weight, height, and BMI. The patient age range was 3.
