The size of the valve must match the size of the person or else the patient is at risk for <a href=\"https:\/\/www.heart-valve-surgery.com\/learning\/patient-prosthesis-mismatch\/\">patient prosthesis mismatch<\/a>. The size is also crucial when considering a future valve-in-valve replacement.<\/p>\n<p>We recently received a patient question about aortic valve size and re-replacement from Charlie, who asked, \u201cI had my aortic valve replaced with a 25-millimeter bovine tissue valve. If I need another heart surgery, could transcatheter aortic valve replacement, TAVR, be used to replace that valve?\u201d<\/p>\n<p>I was thrilled when Dr. Nicholas Lopez, a leading cardiac surgeon, agreed to weigh in on Charlie\u2019s question while we were at the Annual Meeting of the Society for Thoracic Surgeons in San Antonio.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.heart-valve-surgery.com\/surgeons\/dr-Nicholas-Lopez-Paducah-Kentucky.php\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full\" src=\"https:\/\/www.heart-valve-surgery.com\/profileImages\/465_129_170.jpg?d=20241206\" alt=\"Dr. Nicholas Lopez (Heart Surgeon)\" width=\"129\" height=\"170\" \/><\/a><br \/>\nDr. Nicholas Lopez (Heart Surgeon)<\/p>\n<p>&nbsp;<\/p>\n<h2>Key Learnings About Aortic Valve Sizing<\/h2>\n<p>Here are important insights shared by Dr. Nicholas Lopez during our interview:<\/p>\n<ul>\n<li>Correct sizing of the valve is a priority. Lopez stated, \u201cSo, sometimes knowing a little more about somebody actually helps to get a better answer. But in general, the larger the size of the valve, the better that valve is going to fit that person. When that person is getting surgery, we absolutely want to try to size that valve to that person. And we have some measurements that we can get that valve to what we think they are.\u201d<\/li>\n<li>Upsizing will help with valve efficiency. \u201cAs surgeons, we try to upsize once, if not twice, to fit that person and give them a little more leeway for the most effective, efficient valve,\u201d said Dr. Lopez. \u201cIf that valve is a 25, very likely a TAVR valve can be placed without much difficulty and still achieve a highly efficient valve and not have some stenosis, which is what we do not want to have.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5196 size-full aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/upsizing-aortic-valve-tavr.jpg\" alt=\"Upsizing an aortic valve for TAVR\" width=\"650\" height=\"365\" \/><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>\u201cFracturing\u201d can help make a valve larger. Dr. Lopez said, \u201cAnother solution that can be done is to sometimes open that valve up with a balloon so we can make that valve larger. The term is called fracturing, and that can allow us to squeeze in another valve that may be too small for that individual.\u201d<\/li>\n<li>As Dr. Lopez was explaining fracturing, we received another patient email from Valerie, who has a 21-millimeter valve. I asked if fracturing could be applied with a valve of Valerie\u2019s size. Dr. Lopez said, \u201cAbsolutely. When you start looking at the different valves available, a 19-millimeter tends to be the smallest tissue valve, a 21-millimeter is the next size up. That valve may be perfectly appropriate for her. The problem is as you start getting toward the smaller size valves, sometimes it may not be the most effective valve with another placed within it because, at the end of the day, it will be slightly smaller inside every time. So that\u2019s where you can go ahead and take a balloon and literally crack open the actual rim of that valve. Then that gives us new space to go ahead and put in a valve that is appropriate for her.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h1>Thanks Dr. Lopez!<\/h1>\n<p>On behalf of the patients at HeartValveSurgery.com and patients across the world, thank you, Dr. Lopez, for sharing your expert insight into aortic valve sizing for TAVR re-replacement procedures.<\/p>\n<p>Related Links:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.heart-valve-surgery.com\/learning\/home-alone-after-tavr\/\">Surgeon Q&amp;A With Dr. Lopez: Is It Safe To Be Home Alone After TAVR?<\/a><\/li>\n<li><a href=\"https:\/\/www.acc.org\/Latest-in-Cardiology\/Articles\/2022\/09\/08\/12\/21\/Bioprosthetic-Valve-Fracture-and-Remodeling-During-Valve-in-Valve-TAVR\">Bioprosthetic Valve Fracturing and Remodeling During Valve-in-Valve TAVR <\/a><\/li>\n<\/ul>\n<p>Keep on tickin!<br \/>\nAdam<\/p>\n<p>P.S.
