MSK: Marfan Syndrome: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Marfan Syndrome🎧 A high-yield breakdown of this genetic connective tissue disorder – ideal for MSRA prep and clinical understanding.🧠 Key Learning Points📌 Definition• Marfan syndrome is a genetic disorder of connective tissue caused by a mutation in the FBN1 gene.• Affects multiple systems: skeletal, cardiovascular, and ocular.📌 Causes & Risk Factors• Mutation in the FBN1 gene on chromosome 15• Inherited in an autosomal dominant pattern• 25% of cases are sporadic (de novo mutations)• Increased risk with positive family history🧠 Mnemonic: “SCAR” – Skeleton, Cardiovascular, Aorta, Retina📌 Pathophysiology• Abnormal or deficient fibrillin-1 → weak connective tissue• Leads to elongation, hypermobility, and aortic wall defects• Aortic root dilatation is a critical complication📌 Symptoms• Tall stature, long limbs, arachnodactyly• Joint hypermobility• Aortic root dilatation, murmur (mitral valve prolapse)• Ectopia lentis (lens dislocation), high myopia• Scoliosis, high-arched palate, spontaneous pneumothorax🧠 Signs: Walker’s sign, Steinberg’s thumb sign📌 Differential Diagnosis• Ehlers-Danlos syndrome• Loeys-Dietz syndrome• Familial thoracic aortic aneurysm• Acromegaly, Fragile X• Homocystinuria (lens dislocation + thrombosis)📌 Diagnosis• Clinical history + exam (multisystem involvement)• Echocardiogram (aortic root) – annually• MRI/CT of aorta if needed• Ophthalmology assessment• Pelvic X-ray for protrusio acetabuli• Genetic testing for FBN1• Use Ghent criteria for structured diagnosis📌 Management• MDT approach: cardiology, ophthalmology, genetics• Lifestyle: avoid contact sports, heavy lifting• Beta-blockers or ARBs (e.g. losartan) to reduce aortic stress• Surgical repair if aortic root > certain size threshold• Valve-sparing aortic root replacement preferred• Pregnancy = high risk, needs specialist care• Annual surveillance essential📌 Complications• Aortic dissection/rupture – major cause of death• Mitral valve prolapse• Retinal detachment• Scoliosis, pneumothorax, dural ectasia📌 Prognosis• Life expectancy is now normal with early diagnosis and proper monitoring• Cardiovascular complications remain the key threat• Lifelong surveillance is critical for long-term outcomes📎 More MSRA Resources for Marfan Syndrome📝 Revision Notes:https://www.passthemsra.com/topic/marfans-syndrome-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/marfans-syndrome-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/marfans-syndrome-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/marfans-syndrome-rapid-quiz/🎓 Full MSK Course:https://www.passthemsra.com/courses/msk-for-the-msra/🧪 Quiz Bank:https://www.passthemsra.com/quizzes/marfans-syndrome/#MSRA #MSRARevision #MarfanSyndrome #Genetics #CardiovascularRisk #MSRAFlashcards #MSRAQuiz #PassTheMSRA #MSRAQuestionBank #MSRAQandA #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #ConnectiveTissueDisorder
