Transcatheter Recanalization of Atretic Pulmonary Veins in Infants and Children

Utility of simultaneous triple balloon inflation technique through a single 6-French sheath in treating pulmonary vein stenosis

Pulmonary vein stenosis continues to pose significant challenges in children, frequently requiring repeated cardiac catheterisation procedures. This report describes a successful application of a "triple kissing balloon" technique to treat complex pulmonary vein stenosis in two patients, all accomplished with the use of a single 6-French sheath.

Transcatheter recanalization of chronic total occlusion in congenital heart disease: case reports and lessons from percutaneous coronary interventions

Background

Chronic complete vascular occlusion causes significant morbidity and mortality in patients with congenital heart disease (CHD). The diversity of lesions, lack of dedicated equipment, and small number of procedures performed by individual operator continue to pose a challenge to congenital interventional cardiologists.

Case summary

We report two cases of percutaneous recanalization in CHD using percutaneous coronary intervention (PCI) equipment for chronic total occlusion (CTO).

Discussion

Careful pre-procedural planning, access site choice, use of catheter guiding systems for support, and selection of penetrating guidewires and techniques used in CTO-PCIs are key steps to a successful outcome.
