For the hearing impaired members of our community, I posted a written transcript of my interviews with John and Dr. Malaisrie below.<\/p>\n<p class=\"Interviewer\">John Pascarella: My name&#8217;s John Pascarella. I live in Frankfurt, Illinois. My father, he was 58 years old when he had coronary bypass surgery, and on my mom&#8217;s side, a couple of my uncle&#8217;s on her side had heart attacks. It&#8217;s definitely in my family, so I really didn&#8217;t go to the doctor until I was 65 and went for my Medicare physical. He asked me if I had any problems. I told him I had a slight heart murmur. He says, \u201cJohn,\u201d he says, \u201cYou have a severe aortic stenosis, and it&#8217;s something you&#8217;re going to have to go see a cardiologist. This is something we&#8217;ve got to take seriously. \u201cWhat I&#8217;m going to want you to do,\u201d he says, \u201cI&#8217;m going to send you to a surgeon,\u201d he says, \u201cDr. Chris Malaisrie at Northwestern.\u201d \u00a0My first reaction was, well, if I go see the surgeon, he&#8217;s going to want to do surgery. He says, \u201cNo, not necessarily. He&#8217;s going to tell you what it is, you know.\u201d<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full aligncenter\" src=\"https:\/\/www.heart-valve-surgery.com\/profileImages\/312_129_159.jpg\" width=\"129\" height=\"159\" \/>Dr. Chris Malaisrie<\/p>\n<p>&nbsp;<\/p>\n<p class=\"Interviewer\">Dr. Chris Malaisrie: \u00a0Bicuspid aortic valve is one of the most common congenital heart problems. We estimate that approximately 1 to 2% of the general population will have a bicuspid aortic valve. Mr. Pascarella was born with an abnormal heart valve. He eventually developed aortic stenosis, which is calcification of the aortic valve, restricting the blood flow out of the heart. In addition, he also had an aortic aneurysm, which is common in patients with bicuspid aortic valve.<\/p>\n<p class=\"Interviewer\">John Pascarella: I didn&#8217;t feel like I was ready at that time because I had no symptoms.<\/p>\n<p class=\"Interviewer\">Dr. Chris Malaisrie: Many patients with bicuspid aortic valve don&#8217;t need surgery right away, so we follow our patients with 4D MRI. The MRI flow with the advanced technology we have is able to demonstrate wall shear stress and abnormal blood flow. We can follow these patients and follow their abnormal blood flow within the aorta. The pattern of blood flow does make a difference in terms of progression, and when is the appropriate time to recommend surgery. When he developed symptoms, he came to see us and we had recommended a minimum invasive approach to fix both his aortic valve and his aortic aneurysm.<\/p>\n<p class=\"Interviewer\">John Pascarella: I had minimally invasive surgery, so I had a small incision. It was only about four inches, maybe at the most. I had my aorta repaired and aortic valve replaced. The recovery was great.<\/p>\n<p class=\"Interviewer\">Dr. Chris Malaisrie: Mr. Pascarella did great after his minimally invasive aortic valve replacement and aneurysm repair. We know that minimally invasive cardiac surgery can reduce the trauma associated with open-heart surgery and enhance recovery for our patients. We&#8217;re glad to see him get back to work very quickly with great results.<\/p>\n<p class=\"Interviewer\">John Pascarella: Everybody was great, from the nurses, to technicians, to the \u2013 everyone. Dr. Malaisrie and his team, they&#8217;re awesome.<\/p>\n<p class=\"Interviewer\">Dr. Chris Malaisrie: Our BAV program has been in existence now for five years, and we have brought together a multi-disciplinary approach for the treatment and management of our patients with a bicuspid aortic valve. We&#8217;d like to finally thank all of our patients who&#8217;ve contributed data to our bicuspid aortic valve program in order to make lives for future patients with bicuspid valves better.<\/p>\n<p class=\"Interviewer\">John Pascarella: I can run. I can lift weights. I can do whatever I want. Before that, I couldn&#8217;t. I had all the restrictions on me leading up to the surgery. Overall, it was a good experience. It wasn&#8217;t something I was actually looking forward to, but now that it is completed, I mean, it gives you a new outlook on life.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-24700\" src=\"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/..\/Images\/fb-john.jpg\" alt=\"\" width=\"600\" height=\"314\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":24685,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[68],"tags":[],"class_list":["post-24681","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\/24681","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=24681"}],"version-history":[{"count":1,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/posts\/24681\/revisions"}],"predecessor-version":[{"id":38013,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/posts\/24681\/revisions\/38013"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/media\/24685"}],"wp:attachment":[{"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/media?parent=24681"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/categories?post=24681"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.heart-valve-surgery.com\/heart-surgery-blog\/wp-json\/wp\/v2\/tags?post=24681"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
