Transthoracic open surgical ligation (TTOSL) of patent ductus arteriosus (PDA) remains the most readily available and affordable treatment option in resource-poor countries such as Nigeria.To determine the incidence and outcome of aortic valve regurgitation (AR) following TTOSL of PDA.Retrospective audit of consecutive patients who underwent TTOSL of PDA over a 4½-year period (January 2015 to June 2019) at the OAUTHC, Ile-Ife, Nigeria. Hospital records including echocardiograms (pre-operative, immediate post-operative and follow-up performed a day after TTOSL, at 1, 3 and 12 months) were reviewed for presence and severity of AR.Twenty-six patients (11 males and 15 females) aged 3 months 24 years (Mean = 3.16 years) had TTOS PDA ligation. Only 3 (11.5%) patients had AR pre-operatively; 2 graded moderate AR and 1 graded mild. Twenty (76.9 %) patients had immediate post-operative AR; 4 (20.0%) of which were moderate and the others (80.0%) were mild. Eighteen (69.2%) patients still had AR post-operative day 1; 16 were mild and the rest 2 which were moderate were the same patients that had AR pre-operatively. At 3 months follow-up, 6 of 20 patients (30.0%) had AR; all were mild. Only 2 of 18 (11.1%) followed up for 12 months had AR. They both had had moderate AR pre-operatively which were now graded as mild. There was no mortality.Aortic regurgitation is common after TTOSL of PDA. However, in most instances, it is mild and transient. |
