ReviewReal-time magnetic resonance imaging: diagnostic and interventional applications.
The advent of ultra-fast imaging techniques has extended the utility of magnetic resonance imaging (MRI) from a static and purely diagnostic status to an imaging modality ideally suited for a number of therapeutic applications. These advances--along with the recent development and refinement of miniature intravascular imaging catheters and MRI-compatible guidewires, balloon catheters, and radiofrequency ablation catheters--have created an exciting forum of novel approaches for detecting and treating both acquired and congenital cardiovascular disease. ⋯ Early diagnostic and therapeutic applications, such as high-resolution intravascular and intracardiac imaging, balloon angioplasty, stent placement, and radiofrequency ablation techniques, are discussed and extended to several potential approaches specific to pediatric cardiac therapeutic catheterization. Lastly, safety aspects of MR-guided interventional procedures are presented.

ReviewAortic arch anomalies associated with chromosome 22q11 deletion (CATCH 22).
Chromosome 22q11 deletion or CATCH 22 is associated with DiGeorge syndrome, conotruncal anomaly face syndrome, and velocardiofacial syndrome. Associated congenital heart diseases include tetralogy of Fallot, truncus arteriosus, and ventricular septal defect. Associated anomalies of the aortic arch, aortic branches, ductus arteriosus, and pulmonary arteries are more frequent in patients with the deletion than in those without the deletion. Associated anomalies include right aortic arch, cervical aorta, aberrant origin or isolation of the subclavian artery, the absence of the ductus arteriosus, major aortopulmonary collateral arteries, isolation of the left pulmonary artery, and vascular ring formed by the right aortic arch, retroesophageal aortic arch, and left descending aorta.

ReviewTetralogy of Fallot with major aortopulmonary collaterals: early total repair.
Tetralogy of Fallot with pulmonary atresia and major aortopulmonary collaterals is a complex lesion distinguished by marked heterogeneity of pulmonary blood supply. Over the past two decades, investigators have developed various approaches to the management of this anomaly generally based on the concept of staged unifocalization of pulmonary blood supply. ⋯ We aim to repair these patients early in infancy, with an emphasis on native tissue-tissue reconstruction, in order to optimize prospects for survival with a good functional outcome in as many patients as possible. In this review, we present our philosophy and our experience with unifocalization and repair in 72 patients.
