There are stark differences in size, structure, and function.<sup>1,2<\/sup>\u00a0 Yet, for decades, most clinical heart research and diagnostic criteria have centered around men. This lack of differentiation has led to mis-diagnosis and under-treatment of women with symptoms of heart disease.<\/p>\n<p>Aortic stenosis is a prime example of the structural heart differences in men and women. Women tend to have a smaller aortic annulus, or valve opening, than men. This anatomical difference has sometimes led to considerable challenges for doctors and how they choose to treat aortic stenosis. Despite women\u2019s longer life expectancy, once impacted by severe aortic stenosis, they suffer from higher mortality than men, even after matching for age.<sup>3<\/sup>\u00a0\u00a0 However, if women do receive treatment, they have a lower mortality rate and excellent outcomes with TAVR compared to SAVR.<sup>4,5<\/sup><\/p>\n<p>Until recently, there has been limited randomized controlled data regarding the treatment for aortic stenosis for patients with a small aortic annulus, most of whom are women. Medtronic\u2019s SMART Clinical Trial <a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa2312573\">results<\/a> now shed light on this patient population. To learn more, we recently traveled to the Women\u2019s Heart Health Congressional Day in Washington, D.C., where we met with <a href=\"https:\/\/profiles.mountsinai.org\/roxana-mehran\">Dr. Roxana Mehan<\/a>, who is a Professor of Medicine and Director of Interventional Cardiovascular Research and Clinical Trials at Mount Sinai School of Medicine in New York City, New York.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/dyzHQ6MnrqA?rel=0?si=ig3LS1G0avP39UcN\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h2><\/h2>\n<h2>Key Learnings About The SMART Clinical Trial<\/h2>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5100 aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/smart-trial-evolut.jpg\" alt=\"Smart Clinical Trial\" width=\"650\" height=\"346\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Here are the important insights shared by Dr. Mehran during our interview:<\/p>\n<ul>\n<li>What should patients know about Women\u2019s Heart Health Congressional Day? \u201cIt\u2019s historic if you think about it,\u201d said Dr. Mehran. \u201cI don\u2019t remember that we would have a whole day dedicated to women\u2019s heart health on The Hill, and here we are talking to our representatives from around the country about the importance and the crucial time point we\u2019re in. We are at an inflection point of saving women\u2019s lives.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5101 aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/women-heart-health-challenges-mehran.jpg\" alt=\"Women Heart Health Challenges\" width=\"650\" height=\"365\" \/><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>Based on your professional experience, what are the fundamental challenges for women with heart disease? \u201cWell, it\u2019s a huge challenge,\u201d said Dr. Mehran. \u201cWomen aren\u2019t believed. They come in with really serious symptoms, and they\u2019re ignored. Heart disease is the number one killer, yet awareness that heart disease is the number one killer has decreased over the last couple of decades. We\u2019re losing lives every few seconds, and we\u2019re starting to see, especially in younger women, higher death rates. We have to put a stop to that.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Studies show that women are underdiagnosed, under-treated, and under-represented in clinical trials. Is this accurate and what can patients learn from this information? \u201cIt\u2019s totally accurate when they come in with a heart attack or symptoms of a heart attack. They\u2019re often under-recognized, pushed aside, told they&#8217;re fine and to go home,\u201d said Dr. Mehran. \u201cOn the clinical trial side, almost every device and drug out there has been studied in white men. Do we have answers for women? Do the results we use for our guidelines and how clinicians make decisions relate to women? Many don\u2019t.\u201d<sup>,1, 2,6,7<\/sup><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Is it true that about 35 percent of women who are indicated for surgery because of aortic stenosis don\u2019t get an aortic valve replacement? Mehran said, \u201cYes. Aortic stenosis is a disease that\u2019s prevalent in women. Yet, the diagnosis is not well done. When there is a diagnosis, they wait longer to be referred for definitive therapy, which is an aortic valve replacement, whether it\u2019s going to be surgery or a minimally invasive approach, with what we call TAVR. These are the big questions that women should be asking their doctors.\u201d<sup>7<\/sup><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Does heart valve disease impact women differently than men? \u201cAbsolutely,\u201d said Dr. Mehran. \u201cWomen are not small men. We keep hearing this, and I keep saying it. The pathology or the way our valves are blocked differs greatly from how men\u2019s valves get blocked. We know that there are important sex differences. The way the heart responds to the blocked valve is different than in men.\u201d Dr. Mehran explained that looking at women\u2019s distinct biology is imperative to understand how best to treat them.<sup>1, 2<\/sup><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5102 aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/Smart-Clinical-Trial-Women-Enrollment.jpg\" alt=\"Smart Clinical Trial Women Enrollment\" width=\"650\" height=\"366\" \/><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>What is the SMART Clinical Trial, and how does it relate to today\u2019s event? Dr. Mehran said, \u201cThe SMART Clinical Trial is a pivotal trial that we are very proud of.\u201d She explained that for the first time, they looked at aortic stenosis in patients with small annuli, which is more prevalent in women. \u201cFor the first time, we enrolled almost 90 percent of women, and now we have an answer for our women who have aortic stenosis with a small annulus and which valve they should get.\u201d<sup>8<\/sup><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5104 aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/learning\/..\/Images\/evolut-smart-clinical-trial-medtronic.jpg\" alt=\"Evolut TAVR Valve Smart Clinical Trial\" width=\"650\" height=\"363\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>What were the key one-year findings of the SMART Clinical Trial? \u201cWe showed that the Medtronic Evolut self-expanding valve had similar clinical outcomes with the balloon-expandable SAPIEN valve, but with the very important difference of how patients felt,\u201d Dr. Mehran explained. \u201cThey felt better with the Evolut valve. As we followed these patients with the ultrasound, it looked like their valves were more open, more functional, and better regarding how much blood was getting to the rest of their bodies. It is a very important finding, and over time, I think it will show a difference in the clinical outcome.\u201d<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>TAVR risks may include, but are not limited to, death, stroke, damage\u00a0to the arteries, bleeding, and need for permanent pacemaker.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>What can patients in the HeartValveSurgery.com community do to improve women\u2019s heart health? Mehran explained that patients with aortic stenosis can ask their doctor these critical questions:\n<ul>\n<li>Is my heart valve small?<\/li>\n<li>Is my annulus small?<\/li>\n<li>Which valve will you put in?<\/li>\n<li>Does the valve open by itself?<\/li>\n<li>Does the valve open with a balloon?<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h1>Thanks Dr. Mehran, Mount Sinai and Medtronic!<\/h1>\n<p>On behalf of patients at HeartValveSurgery.com and patients worldwide, thank you, <a href=\"https:\/\/profiles.mountsinai.org\/roxana-mehran\">Dr. Mehran<\/a>, for everything you and your team are doing at Mount Sinai Health for patients with aortic stenosis and heart valve patients everywhere.\u00a0 We also need to thank Medtronic, the manufacturer of the Evolut TAVR that was studied in the landmark SMART Clinical Trial.<\/p>\n<p>Related Links:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.heart-valve-surgery.com\/medtronic-tavr-procedure\">See the new Medtronic TAVR Procedure Educational Microsite<\/a><\/li>\n<li><a href=\"https:\/\/www.heart-valve-surgery.com\/medtronic-tavr-heart-team-finder\">Research 50 Leading Heart Teams the Specialize in Medtronic TAVR<\/a><\/li>\n<li><a href=\"https:\/\/tavrfinder.com\/3cfjym95\">Free eBook: What 7 Facts Should You Know About TAVR?<\/a><\/li>\n<\/ul>\n<p>Keep on tickin!<br \/>\nAdam<\/p>\n<p>References:<\/p>\n<ol>\n<li>Nau DP, Ellis JJ, Kline-Rogers EM, Mallya U, Eagle KA, Erickson SR.
