Successful closure of left-to-right patent ductus arteriosus in three dogs with concurrent pulmonary hypertension.
Closure of reversed patent ductus arteriosus (PDA) is generally accepted to be contraindicated due to case based evidence of worsened outcomes, but little is known about closure of left-to-right PDA with concurrent pulmonary hypertension (PH). This report describes three dogs presenting with varying severity of PH and clinical signs, all with documented left-to-right PDA. The PDA was closed in each case; either by surgical ligation or transarterial device occlusion, and follow up was available for a minimum of 8 months. Every case had a successful outcome with improvement or resolution of PH and associated clinical signs.
