Key result
Foetal percutaneous aortic valve balloon valvuloplasty followed by a postnatal Ross-Konno procedure with fibroelastosis resection allowed left ventricular growth and conversion to a biventricular circulation.
Case Report (n=1)
A complex sequence of foetal and postnatal interventions, including a Ross-Konno procedure, can successfully achieve biventricular circulation in patients with foetal aortic stenosis and borderline left ventricle.
We report a case of a patient who presented with aortic stenosis and a borderline left ventricle during foetal life. A balloon aortic valve valvuloplasty was performed in uterus, and in the postnatal period for relief of the left ventricular outflow tract obstruction followed by a Ross-Konno procedure with fibroelastosis resection. These successful interventions allowed left ventricular growth and the conversion to a biventricular circulation after a single-stage surgery.

Pérez-Negueruela et al. (2014) conducted a case report in Aortic stenosis and borderline left ventricle (n=1). Foetal percutaneous aortic valve balloon valvuloplasty followed by postnatal balloon valvuloplasty and Ross-Konno procedure with fibroelastosis resection was evaluated on Left ventricular growth and conversion to a biventricular circulation. Foetal percutaneous aortic valve balloon valvuloplasty followed by a postnatal Ross-Konno procedure with fibroelastosis resection allowed left ventricular growth and conversion to a biventricular circulation.
