Transvalvular leakage after the implantation of stented bovine pericardial valves is not only central

Technical Details of Aortic Valve Replacement using Carpentier–Edwards PERIMOUNT Magna Ease Aortic Bioprosthesis in a Sexagenarian Patient with Severe Calcific Aortic Stenosis: A Video Presentation

“…Three patients with cuff leakage were managed conservatively, and in one patient, it was sutured using polypropylene suture. [26][27][28][29] Pledgeted mattress sutures like we have used in our case in this manuscript have been advocated by other authors to prevent this complication. 29 We report herein a 61-year-old male patient (body surface area 1.7 m 2 ) diagnosed with severe calcific aortic stenosis, with a peak systolic left ventricle-to-aortic gradient of 110 mm Hg and normal coronaries undergoing aortic valve replacement using a 21 mm Carpentier-Edwards PERIMOUNT Magna Ease aortic prosthesis under moderately hypothermic cardiopulmonary bypass, St. Thomas (II)-based cold blood cardioplegia and iced normal saline.…”

Regurgitant leak from the area between the stent post and the sewing ring of a stented bovine pericardial valve implanted in the aortic valve position

“…This is physiologic regurgitation that usually only requires monitoring, and not treatment. Another non-central type of leakage within the sewing ring is also known, though only a few cases have been reported [2,3]. The leak, which originates from the fabric-covered regions of the stent struts or from the region between the stent and the sewing ring in stented porcine heterografts or stented bovine pericardial valves [1-3], is not classified as a paravalvular leak because it originates inside the sewing ring.…”

Instead, it is classified as non-central transvalvular leakage which originates outside the bioprosthetic annulus [2,3]. The leak might be due to a structural problem associated with the material of the fabric, because these regurgitant jets leak through the fabric of the bioprosthetic valve [1].…”
