Simultaneous Balloon Technique for Adjusting Placement of a Self-Expanding Pulmonary Valve.

ABSTRACT:

Objective

To describe the use of a balloon-assisted technique for placement of a Harmony valve in a patient with tetralogy of Fallot and a dilated right ventricular outflow tract (RVOT).

Key steps

Harmony valve malalignment can happen with pyramidal-type outflow tracts. Using a large compliant balloon, we inflated the balloon across the misaligned segment of the partially deployed Harmony valve. Once correctly aligned in the RVOT, we proceeded with standard deployment.

Potential pitfalls

Retrieval of the valve back into the delivery catheter can be difficult to impossible and may require use of a Gore 26-F DrySeal sheath to retrieve.

Take-home messages

Complex and dilated RVOTs make deployment of self-expanding valves difficult, with a higher probability of mal
