I have performed a total of 35 minimally invasive MVRepairs with an anterior leaflet augmentation for multiple different pathologies including rheumatic disease. severe MAC, radiation valvulopathy, and severe SAM with IHHS.
33 have been with bovine pericardium, 1 with untreated autologous pericardium and 1 with CardioCel. I have not used CorMatrix because of the multiple reports claiming that on the left side of the heart, there can be a disruption of the patch. I cannot personally attest to this since I have only used it once on a tricuspid valve reconstruction.
The last of the 35 cases that I performed an anterior leaflet augmentation was with CardioCel. I found it very comfortable to work with. It is very flexible and soft and it is easy to pass a 5-0 needle through it. A saline test of the valve can be performed with this material as opposed to bovine pericardium which is very stiff and competency of the repair can only be assessed once the heart is beating.
I think this will be my go to patch for now and would like to eventually compare its results with the bovine pericardial cases. Of note, I have been told that all of the bovine pericardial patches will eventually calcify but I have not seen that yet since my follow up is not long enough.
I have enclosed pictures. All of my cases have been performed via a right lateral mini thoracotomy. I truly believe that the visualization is superior to a sternotomy in addition to the fact that a more extensive and complete myectomy can be performed via the mitral valve.
