Evaluation of the short-term outcomes of Ross-Konno operation at Heart Center, Vietnam National Children’s Hospital. Methods: From August 2016 to May 2022, 20 consecutive patients underwe22nt Ross-Konno operation at Heart Center, Vietnam National Children’s Hospital was retrospectively reviewed. Results: The median age and median weight of the patients in our study were 1.02 years (0.14 - 6.07 years) and 7.75 kg (3.7 - 26 kg), respectively. There were 15 males and 5 females. Preoperative diagnosis was: severe aortic valve stenosis (8 patients), severe aortic valve insufficiency (4 patients), and coarctation of the aorta-ventricular septal defect-left ventricular outflow tract obstruction (4 patients). The preoperative median Z-score of the aortic valve was -4.53 (-10.5, 0.75) in 16 patients who have aortic valve stenosis of left ventricular outflow tract obstruction. The mean aortic cross-clamp time was 131 39.7 minutes, the mean bypass time was 190 44 minutes, and the ventilation time was 168 hours (16.5 – 2420 hours). In-hospital mortality was 5% (1 patient) and late mortality was 5% (1 patient). The latest echocardiography showed 1 patient have mild-moderate aortic valve insufficiency, and all survivor have none or trivial aortic valve insufficiency. The median time of follow-up was 12 months (0.5 – 60 months), with 1 patient requiring reintervention due to right pulmonary stenosis. The survival of these patients was 88.2% at 5 years of follow-up. Conclusions: Primary results of the Ross-Konno operation at Heart Center, Vietnam National Children Hospital were good and effective. Another study with longer follow-up and a bigger number of patients was essential.
