from flowing back between the left atrium and left ventricle malfunctions, causing blood to flow backward in the heart. This puts strain on the heart and leads to symptoms of heart failure such as shortness of breath.<\/h4>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-36705fc4 elementor-widget elementor-widget-text-editor\" data-id=\"36705fc4\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The heart works as a pump to send blood throughout the body and is divided into four chambers. The two on the right are called the right atrium and right ventricle, while the two on the left are called the left atrium and left ventricle. Each chamber is separated by valves. Oxygenated blood from the lungs is sent to the left atrium, passes through the mitral valve, and enters the left ventricle, which plays a central role in pumping blood to the entire body. The mitral valve is shaped like a parachute and is fixed to the left ventricle by numerous string-like tissues called chordae tendineae. This allows the mitral valve to close completely and prevent backflow when the left ventricle contracts to send blood throughout the body. <strong>If these chordae tendineae are stretched or torn, the mitral valve cannot close completely when the heart contracts, resulting in regurgitation<\/strong>. This condition is <strong>mitral valve regurgitation<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-55cd8d31 elementor-widget elementor-widget-image\" data-id=\"55cd8d31\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"365\" src=\"https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/01\/mr_\u56f31-1024x467.jpg\" class=\"attachment-large size-large wp-image-8926\" alt=\"\" srcset=\"https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/01\/mr_\u56f31-1024x467.jpg 1024w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/01\/mr_\u56f31-500x228.jpg 500w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/01\/mr_\u56f31-768x350.jpg 768w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/01\/mr_\u56f31.jpg 1298w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-34353233 elementor-widget elementor-widget-text-editor\" data-id=\"34353233\" data-element_type=\"widget\" id=\"cardiogram\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4><strong>Symptoms of Mitral Valve Regurgitation<\/strong><\/h4><p>When regurgitation becomes severe, the backflowing blood accumulates in the lungs, causing <strong>shortness of breath and swelling<\/strong>. When symptoms first appear, drug therapy such as diuretics can be used to reduce blood volume, alleviate lung swelling, reduce the burden on the heart, and relieve symptoms. However, as the condition progresses, these medications may become ineffective, making it difficult to breathe even when lying down, necessitating hospitalization. Even after hospitalization and temporary improvement of heart failure, the condition is progressive, leading to repeated hospitalizations and potentially life-threatening situations. To prevent the exacerbation of heart failure, surgery to reduce regurgitation is the most effective measure.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element

Safe, Reassuring, and Comfortable Healing Environment with All Private Rooms<\/strong><\/h5><p>If post-operative progress is favorable, patients are transferred to the general ward the day after surgery to focus on rehabilitation (*this may vary depending on individual patient progress). All rooms in our general ward are private, allowing patients to relax in a quiet environment and focus on post-operative recovery. This not only protects your privacy but also provides a safe and reassuring environment by reducing the risk of infection from other patients.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a274375 elementor-widget elementor-widget-image\" data-id=\"a274375\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"459\" src=\"https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/03\/\u30cf\u30fc\u30c8\u30c1\u30fc\u30e03-1024x588.jpg\" class=\"attachment-large size-large wp-image-8941\" alt=\"\" srcset=\"https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/03\/\u30cf\u30fc\u30c8\u30c1\u30fc\u30e03-1024x588.jpg 1024w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/03\/\u30cf\u30fc\u30c8\u30c1\u30fc\u30e03-500x287.jpg 500w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/03\/\u30cf\u30fc\u30c8\u30c1\u30fc\u30e03-768x441.jpg 768w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/03\/\u30cf\u30fc\u30c8\u30c1\u30fc\u30e03-1536x882.jpg 1536w, https:\/\/cardiovascularcenter.luke.ac.jp\/wpdata\/wp-content\/uploads\/2023\/03\/\u30cf\u30fc\u30c8\u30c1\u30fc\u30e03-2048x1176.jpg 2048w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-227b9785 back-to-top elementor-widget elementor-widget-heading\" data-id=\"227b9785\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<span class=\"elementor-heading-title elementor-size-default\"><a href=\"#link-list-treatment\">TOP<\/a><\/span>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-207c01d6 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"207c01d6\" data-element_type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-28f4167d\" data-id=\"28f4167d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-470de9ae elementor-align-center elementor-widget elementor-widget-button\" data-id=\"470de9ae\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm elementor-animation-shrink\" href=\"https:\/\/cardiovascularcenter.luke.ac.jp\/treatments\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon\">\n\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-arrow-circle-left\"><\/i>\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Return to Main Diseases<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Mitral valve regurgitation (MR) is a condition where the valve that prevents blood from flowing back between the left atrium and left ventricle malfunctions, causing blood to flow backward in the heart.
