Ross Operation in the Adult: Long-Term Outcomes After Root Replacement and Inclusion Techniques

Modification of the Ross aortic valve replacement to prevent late autograft dilatation☆

“…Regarding the role of autograft length in the root techniques, de Kerchove and colleagues found that systematic dilatation in patients with long autograft and maximal diameter more frequently observed at the level of the STJ [21]. They conclude that in the root technique, autograft is better when it is as short as possible, with the distal suture line reinforced with a Teflon strip or extended with a Dacron graft [21].…”

“…They conclude that in the root technique, autograft is better when it is as short as possible, with the distal suture line reinforced with a Teflon strip or extended with a Dacron graft [21]. If those reinforcement techniques do not fully protect against autograft root dilatation, some data suggest a benefit from such support of the STJ [22].…”

Left Ventricular Outflow Tract Obstruction

“…For root replacement, autograft dilatation was the main cause of failure. For the inclusion technique, autograft valve prolapse was the main cause of failure [96].…”

Ross Procedure: Prognosis of Pulmonary Autografts

“…De Kerchove et al 5) found that the 10-year rate of survival and freedom from reoperation were the same for both techniques. They concluded that the main causes of failure were autograft dilation and aortic valve prolapse in the full-root and inclusion groups, respectively.…”
