Key result
A hybrid approach using large low-pressure balloons successfully treated severe paravalvar leaks in a child with a mitral Melody valve, with good technical outcomes and no symptoms at 18 months.
Why the study?
There are limited technically oriented reports describing catheter techniques to address Melody valve-related issues, such as paravalvar regurgitation, in infants and young children.
Case Report (n=1)
A hybrid transapical approach using large low-pressure balloons is a feasible technique for managing severe paravalvar leaks in children with a Melody valve in the mitral position.
Hybrid balloon dilatation may manage paravalvar leaks after pediatric Melody implantation; hypothesis-generating and requires prospective validation.
The surgical placement of the Melody®valve in the mitral position in infants and young children was first reported in 2012. Since then, there have only been a limited number of technically oriented reports describing catheter techniques to tackle valve-related issues such as valve adjustment for somatic growth or the management of haemodynamically significant paravalvar regurgitation. We present a case study where severe paravalvar leaks were tackled using a hybrid approach and large low-pressure balloons in a child who had previously undergone Melody® valve implantation in the mitral position. The technical outcome remains very good at 18 months follow-up and the patient remains symptom-free.

Kantzis et al. (2021) conducted a case report in Severe paravalvar leaks after Melody valve implantation in the mitral position (n=1). Hybrid approach using large low-pressure balloons (transapical access for dilatation) was evaluated on Technical outcome and symptom status. A hybrid approach using large low-pressure balloons successfully treated severe paravalvar leaks in a child with a mitral Melody valve, with good technical outcomes and no symptoms at 18 months.
