The medical term for "click-murmur syndrome" is "mitral valve prolapse" (MVP). Mitral valve prolapse is a common condition where the valve between the left atrium and the left ventricle of the heart doesn't close properly. Instead of closing tightly, the valve's leaflets bulge back into the left atrium during the contraction of the heart. This bulging can create a clicking sound (click) and may cause a heart murmur (murmur) as blood flows through the valve. Mitral valve prolapse is typically benign and doesn't always require treatment, but in some cases, it can lead to complications such as mitral regurgitation or infective endocarditis. It's important for individuals with mitral valve prolapse to have regular check-ups with a healthcare professional to monitor their condition.
