Pulmonary valve replacement in a large and tortuous right ventricle outflow tract with a 32 mm Myval valve under local anaesthesia: challenges and technical considerations: a case report

Abstract

Background: Pulmonary valve replacement in patients with congenital heart diseases and heart failure is challenging.

Case summary: Here, we describe a case of a patient who had surgical fallot repair with chronic heart failure. Investigations found severe biventricular dysfunction and enlargement due to chronic pulmonary regurgitation. The right ventricle outflow tract was tortuous and large with a diameter of 35 mm. Percutaneous pulmonary valve implantation (PPVI) was done after a challenging pre-stenting. A 32 mm Myval valve over-sized to 35 mm was used for PPVI, which yielded a good result.

Discussion: A 32 mm Myval valve is effective at extending the possibilities of PPVI in a large and tortuous right ventricle outflow tract not accessible for the other valves.
