The Ross–Konno procedure in neonates and infants less than 3 months of age†

Abstract

The early Ross-Konno procedure can enable biventricular repair even in borderline left ventricles with good long-term outcome. Thus far, there were no reoperations at the level of the autograft or the left ventricular outflow tract in our cohort. The highest operative risk was observed in patients with critical aortic stenosis and aortic arch hypoplasia.

Fetal aortic valvuloplasty may rescue fetuses with critical aortic stenosis and hydrops

“…One of these had only coarctation repair and the other only aortic valve balloon valvuloplasty, leaving significant residual pressure and/or volume load on the already impaired left ventricle. One could speculate that timely Ross–Konno surgery could have been beneficial in this group of patients, as reported previously by our center 9 .…”

Valvuloplasty in 103 fetuses with critical aortic stenosis: outcome and new predictors for postnatal circulation

“…At the age of 1 year, the BV-outcome rate in our cohort of liveborn fetuses with technically successful FAV dropped to 55% owing to postoperative complications and severe persistent diastolic LV dysfunction with increased pulmonary artery pressures in some patients. Postnatal treatment was not uniform among all the managing centers, and not all centers could offer the full spectrum of postnatal treatment 19,20 . However, it has been shown previously that there is a high level of agreement between a multidisciplinary team and surgical centers with respect to postnatal decision-making following fetal cardiac intervention for aortic stenosis 21 .…”

Commentary: Ross procedure in neonates and infants: Withstanding the litmus test of time

“…In other series, the average early mortality of the Ross procedure in infants varies from 7% to 27%. [3][4][5][6] In this retrospective analysis of 35 patients, there was no surgical mortality. Therefore, we have the privilege to comment on a study with among the best early surgical results for Ross/Ross-Konno in infants and neonates.…”
