Minimally invasive pulmonary valve replacement for patient with poststernotomy via left thoracotomy: How to do it?

Objective: To describe the procedure of minimally invasive pulmonary valve replacement for patient with poststernotomy via left thoracotomy. Abstract: minimally invasive surgery (MIS) for congenital heart disease is increasingly with more benifits than traditional heart surgery. MIS is not only applied to the primary heart surgery but is being applied to patient who have undergone traditional heart surgery (sternotomy). We conducted this study to describe the procedure of minimally invasive pulmonary valve replacement for patient with poststernotomy via left thoracotomy. Methods: Desctiptive. From 1/2023 to 11/2024, there were 23 patients who undergone pulmonary valve replacement. They were divided to two groups: Group I included patients with resternotomy and Group II included MIS via left thoracotomy. The mean of age was 9,6 year olds and weight was 24,8 kilograms. Results: no mortality; Group I: the time of cardiopulmonary bypass (CPB) and cardioplegia were 72 mins and 48 mins. Group II: all patients were established with peripheral CPB with beating heart, no patient had to resternotomy. The time of ventilator of group I was 8,4 hours and group II was 1,2 hours. The hospital stay was 12,7 days in group I and 7,4 days in group II. Echocardiography before discharge: all pulmonary valve conduit were competence without stenosis and regurgitation. Conclusion: minimally invasive pulmonary valve replacement for patient with poststernotomy via left thoracotomy was feasible with good early outcome.
