The Konno-Rastan procedure.

ABSTRACT

The Konno-Rastan procedure is an anterior aortoventriculoplasty that has  the aim of relieving subvalvar, valvar, and supravalvar stenosis. It can be helpful for patients with aortic stenosis at any level and also for those with a prior implanted aortic and/or mitral prosthesis.  The patient presented in this video tutorial had a history of rheumatic heart disease with previously implanted mechanical prostheses in the aortic as well as the mitral position. We provide detailed insight on how to perform the Konno incision safely and demonstrate the reconstruction of the aortic root, as well as the ventricular septum and the right ventricular outflow tract using a patch of bovine pericardium.
