I just received a great question from Mary Anne about heart valve anatomy. Specifically, she is interested to learn more about valvular function within the heart.<\/p>\n

Mary Anne writes, “Dear Adam – I was recently diagnosed with severe mitral regurgitation<\/a>. As an active 67-year old grandmother, this has been a difficult time – especially since I’m asymptomatic. However, my heart is already dilated so I’m preparing for surgery. Quick question… If the surgeon can’t repair the valve, I’m thinking about a tissue valve replacement. Do you have any videos that show how tissue heart valves open-and-close? Thanks, Mary Anne”<\/p>\n

So you know, I had this exact question prior to my aortic valve replacement surgery<\/a>. I remember thinking, “How do heart valves replacements work? How do the heart valve leaflets seal?”<\/p>\n

<\/p>\n

To answer those questions, I located three videos (shown below) which illustrate exactly how tissue valve replacements open-and-close. Here is a video of a tissue heart valve replacement made from the leaflets of a pig (also known as a porcine valve<\/a>).<\/p>\n

Here is a video of a valve replacement made from the pericardial tissue of a cow’s heart (Edwards Perimount):<\/p>\n

Here is the video of the stentless valve replacement we discussed yesterday – the ATS 3f Aortic Bioprosthesis.<\/p>\n

I hope this helps Mary Anne (and perhaps you) visually understand how the leaflets of tissue heart valve replacements open and close.<\/p>\n

Keep on tickin!
