Background and Keywords:
OBJECTIVE Patent ductus arteriosus (PDA) has a high incidence, is larger and associated with elevated pulmonary hypertension in patients living at high altitude. The aim of this study is to evaluate the hemodynamic and morphological features of PDA and also investigate the transcatheter closure procedures with various devices in this group.
METHODS A total of 327 patients, living at an altitude of at least 1600 meters above sea level and undergone cardiac catheterization for isolated PDA between May 2010 and July 2018, were analyzed.
RESULTS The mean age was 7.33±7.67 years, 62.4% of the patients were females. The mean ductal diameter was 3.74±2.14 mm. 57.8% of the patients had pulmonary hypertension. Transcatheter closure were performed in 322 patients with a %97.3 success rate. Amplatzer duct occluder I was the most used device. Amplatzer vascular plug (AVP) II and Amplatzer muscular ventricular septal defect occluder (AMVSDO) was the used off-label devices. Pulmonary artery pressure decreased immediately in the vast majority after percutaneous closure. Transient left ventricular systolic dysfunction after ductal closure was observed rarely. Follow-up course was uneventful.
CONCLUSION Transcatheter PDA closure can be performed with high success rate in highlanders. Device embolization is mostly seen in patients with type A duct. Oversizing the device may reduce the incidence of device embolization. Off-label devices such as AVP II and AMVSDO can be safely used in these patients. Transient left ventricular dysfunction is rarely seen in these patients but mostly impairs without any medication.
