Cierre percutáneo del conducto arterioso persistente en pacientes pediátricos con hipertensión pulmonar en un centro cardiovascular en Bogotá entre 2019-2022: resultados a corto plazo
Thesis
Background: Treatment of large PDA with pulmonary hypertension (PH) is challenging. If it is not occluded, large PDA could result in irreversible pulmonary vascular disease. If it is occluded, it can lead right ventricular failure. Objective: To describe the short-term outcomes of interventional therapy for PDA in children with PH at a cardiovascular center in Bogotá between 2019-2022. Methodology: A descriptive and retrospective study was conducted to describe the short-term outcomes of interventional therapy for PDA in children with PH at a cardiovascular center in Bogotá between 2019-2022. Results: Patent ductus arteriosus associated with PH was more frequent in women at 79%. The maximum height was 2782 meters. The average PDA size was 4.6 mm. Those with moderate and large ductus had moderate and severe PH respectively. PASP and mPAP decreased after ductus was occluded. A decrease in RVSP was documented 24 hours after procedure. At one month of follow-up, pressures had normalized. There were no complications. Conclusions: PDA associated with PH was more frequent in girls. A decrease in pressures and normalization was observed at one month of follow-up, despite the altitude. The link between PDA size and PH severity was documented. The results will allow establishing the time and safety of ductal closure in patients with PH caused by PDA.
