Needless to say, this is very exciting!<\/p>\n<p>Keep on tickin!<br \/>\nAdam<\/p>\n<p><!--more--><\/p>\n<p>P.S. for the hearing impaired members of our community, I have provided a written transcript of my interview with Dr. Bae below:<\/p>\n<p>Adam: Hi, everybody. It\u2019s Adam with HeartValveSurgery.com. We\u2019re here at the Heart Valve Summit in Chicago, Illinois, and I\u2019m here with Dr. Richard Bae who leads the Interventional Echo Lab at Minneapolis Heart Institute in Minneapolis, Minnesota. Dr. Bae, thanks for being with us.<\/p>\n<p>Dr. Bae: Thanks for having me, Adam.<\/p>\n<p>Adam: We\u2019ve been answering your questions on Facebook that our community posted. I have a question for you, Dr. Bae, because I understand you\u2019re doing some very new cutting edge implantations of transcatheter devices for mitral valve replacement. Can you share a little bit about what has happened? I had heard that this technology wasn\u2019t going to be ready for years and years.<\/p>\n<p>Dr. Bae: Right. We\u2019ve been working with a company called Tendyne, and they\u2019ve developed a percutaneous mitral valve replacement strategy which goes in through a small incision in the left ventricular apex. It\u2019s a small incision on the side of the chest. Then, the catheter is delivered through a small hole in the tip of the heart and delivered under ultrasound guidance which I\u2019m helping with. Then, it is attached to the outside of the heart by a little tether. It\u2019s a very slick procedure.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-20472\" src=\"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/..\/Images\/Bae_Richard-001-web.jpg\" alt=\"Dr. Richard Bae\" width=\"133\" height=\"200\" \/>Dr. Richard Bae<\/p>\n<p>&nbsp;<\/p>\n<p>We are in the feasibility part of the study. Initially, it was approved by the FDA for ten patients. Now, I think it\u2019s been expanded to 20 patients. We\u2019ve done all seven patients in the United States up to this point. It started in April so we just did our seventh patient earlier this week. Obviously, it\u2019s very early on into the experience, but it\u2019s been moving quickly. So far, all the patients have done well. They\u2019re typically extubated in the operating room, and we\u2019ve had no strokes, no deaths so far.<\/p>\n<p>It looks like a promising technology; a less invasive approach for patients that aren\u2019t good surgical candidates. Obviously, it\u2019s early on, more to come, but so far, it looks promising.<\/p>\n<p>Adam: Great. Dr. Bae, thanks for all the work you\u2019re doing. I do have one follow up questions. You mentioned the candidates; the patients who this technology is potentially suited for. Can you describe about who it might be for and who it is not for?<\/p>\n<p>Dr. Bae: At this point, we\u2019re looking at patients who have leaky mitral valves, severely leakiness who are symptomatic, and who would normally meet the criteria to have their mitral valve operated on, but for other reasons, other health problems, they are not felt to be surgical candidates. This is an option for them to get therapy without the high risk of the open-heart surgery if they\u2019re too high risk patients.<\/p>\n<p>At this point as it\u2019s a feasibility study, it can be due to leakiness because of a problem with the valve, or a problem from a previous heart attack; anything that\u2019s causing severe leakiness of the valve in patients that are not considered surgical candidates. There are some technical factors they have to look at with a CAT scan of the heart before the procedure to make sure that the heart is big enough, that if the valve isn\u2019t going to cause problems inside the ventricle, cause problems with the other valves, that sort of thing. Those are the patients that we\u2019re looking at at this point.<\/p>\n<p>Adam: Great. Dr. Bae, thank you so much for all the great work you\u2019re doing. This feasibility study we really appreciate it. Congratulations on your success. Thanks for coming by and meeting with us.<\/p>\n<p>Dr. Bae: Thanks for having me.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":20470,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[68],"tags":[],"class_list":["post-20461","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-medical-technology"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/posts\/20461","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/comments?post=20461"}],"version-history":[{"count":0,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/posts\/20461\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/media\/20470"}],"wp:attachment":[{"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/media?parent=20461"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/categories?post=20461"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/tags?post=20461"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
