valve disease occurs when one or more heart valves do not open or close properly.<br \/>\n        This may cause blood to flow backward (regurgitation) or restrict forward flow (stenosis),<br \/>\n        leading to symptoms such as shortness of breath, fatigue, or heart failure.\n      <\/p>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"disease-row\">\n<div class=\"disease-row__h\">\n<h2>Our treatment<\/h2>\n<\/p><\/div>\n<div class=\"disease-row__b\">\n<p>\n        Treatment is determined by the affected valve and the type of valve problem, such as regurgitation or stenosis.\n      <\/p>\n<div class=\"disease-callout\">\n<ul class=\"disease-bullets\">\n<li>\n            <strong>Mitral and tricuspid regurgitation:<\/strong><br \/>\n            Valve repair is our preferred approach whenever feasible, in order to preserve the patient\u2019s own valve.\n          <\/li>\n<li>\n            <strong>Aortic valve disease and mitral stenosis:<\/strong><br \/>\n            Valve replacement is often required.\n          <\/li>\n<li>\n            <strong>Aortic valve stenosis:<\/strong><br \/>\n            Transcatheter aortic valve implantation (TAVI) may be an option in selected patients.\n          <\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"disease-row\">\n<div class=\"disease-row__h\">\n<h2>How we individualize treatment<\/h2>\n<\/p><\/div>\n<div class=\"disease-row__b\">\n<div class=\"disease-callout\">\n<ul class=\"disease-bullets\">\n<li>\n          <strong>Repair vs. replacement:<\/strong><br \/>\n          Valve repair is prioritized when appropriate to reduce long-term burden and preserve native valve function.\n        <\/li>\n<li>\n          <strong>Mechanical vs. biological valve:<\/strong><br \/>\n          Mechanical valves are durable but typically require long-term anticoagulation (warfarin).<br \/>\n          Biological valves have a limited lifespan but usually do not require long-term anticoagulation.\n        <\/li>\n<li>\n          <strong>Patient-centered planning:<\/strong><br \/>\n          Treatment options are discussed with each patient, taking into account age, comorbidities, and lifestyle.\n        <\/li>\n<\/ul><\/div>\n<p class=\"disease-muted\">\n      With improvements in the durability of biological valves and the availability of valve-in-valve procedures (such as TAVI in SAV), biological valves are now selected more frequently in appropriate cases.\n    <\/p>\n<\/p><\/div>\n<\/div>\n<div class=\"disease-row\">\n<div class=\"disease-row__h\">\n<h2>Minimally invasive approach \u2014 robotic MICS<\/h2>\n<\/p><\/div>\n<div class=\"disease-row__b\">\n<p>\n      For selected valve procedures, our center performs<br \/>\n      <strong>robotic minimally invasive cardiac surgery (MICS)<\/strong><br \/>\n      using the da Vinci surgical system, without full sternotomy (opening of the breastbone).<br \/>\n      All procedures are performed fully endoscopically.\n    <\/p>\n<div class=\"disease-callout\">\n<ul class=\"disease-bullets\">\n<li>\n          <strong>No sternotomy:<\/strong><br \/>\n          Surgery is performed through small incisions in the chest, avoiding full opening of the breastbone.\n        <\/li>\n<li>\n          <strong>Smaller scars, less pain:<\/strong><br \/>\n          Postoperative discomfort is typically reduced, with a shorter recovery period compared with conventional open-heart surgery.\n        <\/li>\n<li>\n          <strong>Fully endoscopic:<\/strong><br \/>\n          All procedures are performed under complete endoscopic guidance using the da Vinci system.\n        <\/li>\n<li>\n          <strong>Clinical experience:<\/strong><br \/>\n          A total of 40 cases were performed in 2023.\n        <\/li>\n<\/ul><\/div>\n<p class=\"disease-muted\">\n      Robotic MICS is available as a self-funded option.<br \/>\n      Suitability depends on the valve involved,

options are available through the Cardiology Department at the same hospital, including TAVI for aortic stenosis and MitraClip for mitral regurgitation.<br \/>\n      All structural heart cases are evaluated jointly by the Heart Team.\n    <\/p>\n<p class=\"disease-muted\">\n      <a href=\"\/en\/departments\/cardiology\/valvular-heart-disease\/\"><br \/>\n        TAVI &amp; MitraClip \u2014
