Cited in Scopus: 12Ross and Ross-Konno operations are associated with the inherent risk of residual ventricular septal dysfunction and injury to the conduction system. However, comprehensive biventricular functional outcomes on magnetic resonance imaging after Ross and Ross-Konno procedures are unknown. The purpose of this study was to evaluate and compare the degree of electrical and mechanical dyssynchrony using cardiac magnetic resonance imaging in patients late after Ross and Ross-Konno operations. - Congenital heart diseaseOpen Archive
A composite semiresorbable armoured scaffold stabilizes pulmonary autograft after the Ross operation: Mr Ross's dream fulfilled

Cited in Scopus: 34Use of resorbable external reinforcement of the pulmonary autograft during the Ross operation has been suggested, but the differential regional potential for dilation of the aorta, mainly regarding the neo-root and the neo-Valsalva sinuses, represents an unresolved issue. Auxetic materials could be useful in preventing dilation given their favorable mechanical properties. We designed a composite semiresorbable armoured bioprosthesis constituted by polydioxanone and expanded polytetrafluoroethylene and evaluated its effectiveness as a pulmonary autograft reinforcement device in an animal model of the Ross procedure.
