Outcomes of percutaneous balloon pulmonary valvuloplasty in congenital pulmonary valve stenosis

Abstract

Percutaneous balloon pulmonary valvuloplasty (PBPV) is the primary treatment for pulmonary valve stenosis (PVS). The study consisted of 228 children with PVS who underwent PBPV from January 2004 to October 2019 at a single center. The risk factors for ≥moderate pulmonary regurgitation (PR), residual stenosis, and restenosis were analyzed based on the baseline patient characteristics and measured value of corresponding inspection results. Among 228 patients, follow‐up results were obtained in 193 patients. The univariate analysis demonstrated that young age, low weight, small pulmonary annulus diameter, higher initial RV‐PA PSEG, increased RV/systemic pressure ratio, and severe PVS were associated with ≥moderate PR. The multivariate analysis demonstrated that higher initial RV‐PA PSEG and low weight were independently associated with ≥moderate PR, while higher initial RV‐PA PSEG was independently associated with residual stenosis and restenosis. PBPV is a preferred tre atment in PVS children with a higher success rate. Higher initial RV‐PA PSEG was a significant factor for ≥moderate PR, residual stenosis, and restenosis.

Outcome of Balloon Valvuloplasty in Children with Pulmonary Valve Stenosis – Multi-Center Experience

“…Jaing et al (22) reported that the success rate was 90%. The immediate success rate was 89.6% with Yin et al (23) . The possible cause of this difference may be due to the selection bias in our study.…”

“…This result is equivalent to that of Peterson et al (25) , who discovered the development of restenosis in 13 (14.1%) of patients who had undergone BPV; 6 individuals were re-dilated, and 7 individuals required surgery (their study involved 108 patients with a mean age of 3.6 years). According to Yin et al (23) , reported 16.6% of 193 individuals with follow-up data with residual stenosis or restenosis after initial BPV, with 9 needing reintervention.…”

Resultados de la valvuloplastia percutánea con balón en la estenosis valvular pulmonar en población pediátrica en el Instituto Nacional Cardiovascular – INCOR, Lima – Perú

“…La estenosis pulmonar es una cardiopatía congénita acianótica que representa, aproximadamente, 8 a 10% de los defectos cardiacos al nacimiento 1 , 2 . Su presentación puede ser asintomática, con un hallazgo incidental de un soplo, o de grado severo con cianosis, dolor torácico, disnea y falla cardiaca 3 - 5 .…”

Alternative Approach for Pulmonary Valvuloplasty in Critical Congenital Pulmonary Stenosis

“…3 Studies have described percutaneous balloon valvuloplasty to have immediate success with reintervention requirement in fewer cases along with reasonable growth of the RV and that of the pulmonary valve in infants with critical pulmonary valve stenosis. 4,5 However, the procedure often presents technical difficulties because of increased pressure in the RV making it difficult to reach the stenotic pulmonary valve. To overcome this issue certain methods have been devised and used around the world like using a catheter with bent hard end of a guide wire and using trans-jugular approach instead of the routinely used femoral vein.…”
