Oct 1, 2006 · The Ross-Konno procedure is an excellent technique to treat complex multilevel left ventricular outflow tract obstruction in children with significant annular and subannular hypoplasia. The autograft demonstrated durability without development of aortic stenosis or progressive dilation and a low incidence of developing progressive aortic ...

Ross-Konno procedure provides better hemodynamic profile, decreased need for anticoagulation, life expectancy similar to healthy age matched controls, and improved quality of life

May 1, 2021 · We aimed to identify demographic and echocardiographic correlates of transplantation-free survival and reintervention in patients with critical aortic stenosis who underwent the Ross procedure in infancy. We hypothesized that preoperative echocardiographic measures of LV function would relate to transplantation-free survival.

Apr 29, 2020 · Subsequent echocardiograms demonstrated worsening left ventricular outflow tract obstruction with a peak gradient of 67 mm Hg and moderate aortic valve regurgitation. By echocardiogram, the aortic annulus measured 11 mm with preservation of left ventricular function.

The Ross procedure is the only available living aortic valve substitute, preserves mobility of the neo-aortic root, and is the only option for adults, providing a life expectancy that resembles life expectancy in the general population.

Aortoventriculoplasty with pulmonary autograft, “The Ross-Konno” operation, provides more or less a radical solution to multilevel LVOT obstruction by enlarging the aortic annulus and the subvalvular area, thus relieving both valvular and subvalvular obstructions.

An earlier experience from St. Louis with the Ross procedure also documented very good functional results. 15 Thirty-three patients (mean age of 31.4) with aortic valve disease underwent a Ross procedure. Serial echocardiograms were obtained and, at a mean follow up of 24 months, showed good autograft function without late onset aortic ...

Patient 1 presented to the University Hospital in San Antonio on day 1 of life with congestive heart failure requiring intubation and administration of prostaglandin Ep An echocardiogram revealed severe congenital aortic stenosis with a 4-mm aortic annulus and a tremendously dysplastic unicusp-appearing aortic valve.

Oct 15, 2016 · Late follow-up echocardiogram measurements were available in 20 subjects (66%) at a mean of 10.3±5.2 years post-Ross and were compared to an early post-operative echocardiogram obtained at a mean 11±8 days after Ross.

Our data demonstrate that mean age (R, 12.9 years versus RK, 5.3 years; p < 0.001), mean size of allograft (R, 23.3 mm versus RK, 20.1 mm; p < 0.001), previous surgery (R, 51% versus RK, 83%; p = 0.05), and postoperative morbidity (R, 3% versus RK, 28%; p = 0.003) were significantly different between the groups.
