Paediatrics: Ventricular Septal Defects: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Ventricular Septal Defect (VSD)🎧 A clear, high-yield breakdown of this common congenital heart defect – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• A ventricular septal defect (VSD) is a congenital hole in the septum dividing the right and left ventricles• Allows oxygenated blood to mix with deoxygenated blood📌 Causes & Risk Factors• Congenital (incomplete septal formation in utero)• Genetic syndromes: Down syndrome, Trisomy 13/18, Turner syndrome• Maternal factors: diabetes, rubella infection, alcohol, cannabis use💡 Mnemonic: MAGIC – Maternal diabetes, Alcohol, Genetics, Infections, Chromosomal issues📌 Pathophysiology• Left-to-right shunt → increased pulmonary blood flow• Leads to pulmonary hypertension, right heart strain, and eventual heart failure if untreated📌 Symptoms• Small VSDs: asymptomatic + systolic murmur• Moderate/large VSDs: poor feeding, sweating, breathlessness, failure to thrive• Severe: cyanosis (Eisenmenger’s syndrome)💡 Mnemonic: FAST BREATH – Feeding difficulty, Apical impulse, Sweating, Tachypnoea, Breath sounds harsh📌 Differential Diagnosis• Atrial septal defect (ASD)• Patent ductus arteriosus (PDA)• Tetralogy of Fallot• Pulmonary stenosis• Innocent murmurs📌 Diagnosis• Echo – gold standard to assess size, location, flow• ECG – may show LVH or RVH depending on severity• CXR – cardiomegaly, ↑ pulmonary markings• Cardiac catheterisation – if echo unclear or for surgical planning💡 Mnemonic: EEC – Echo, ECG, CXR📌 Management• Small VSDs: monitor, many close spontaneously• Medical: diuretics, ACEi, high-calorie feeds, ± digoxin• Surgical: open repair for significant symptoms• Catheter-based closure: for selected muscular or perimembranous defects• Specialist referral always for symptomatic or large VSDs📌 Complications• Heart failure• Pulmonary hypertension• Eisenmenger’s syndrome• Arrhythmias• Aortic regurgitation (esp. perimembranous)• Infective endocarditis (rare)📌 Prognosis• Small VSDs: excellent prognosis, often close spontaneously• Large VSDs: good outcome with timely surgery• Poor prognosis if Eisenmenger syndrome develops• Most patients can lead normal lives with proper management📎 More MSRA Resources for Ventricular Septal Defect (VSD)📝 Revision Notes: https://www.passthemsra.com/topic/ventricular-septal-defects-vsd-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/ventricular-septal-defects-vsd-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/ventricular-septal-defects-vsd-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/ventricular-septal-defects-vsd-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #VentricularSeptalDefects #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #VSD #PaediatricsMSRA
