Acyanotic

Ventricular septal defect

  • incidence 20%

  • large range

    • fulminant heart failure -> asymptomatic
  • pansystolic murmur (thrill)

  • features of heart failure

  • pulomnary htn if large

    • sternal heave

    • increase p2

  • may decrease in size or close spont

  • treat if large/symptomatic

    • heart fialure

    • ftt

  • surgical repair

  • increase risk of endocarditis

  • Eisenmenger’s syndrome

    • L -> R shunt

    • increase pulm blood flow - pulm. HTN

    • pulm pressures > systemic

    • reversal of shunt R -> L

    • cyansois

    • may occur with untreated BSD/PDA or ASD (rarely)

    • decrease QOL - cyanosis

    • die prematurely

      • arrhythmia and sudden cardiac death

      • bleeding and clotting issues

      • increase risk of systemic emboli

      • haemoptysis

        • pulmonary infarct/haemorrhoage
    • Heart/lung transplant

Atrial septal defect

  • 10-15%

  • F>M

  • Types

    • secundum (commonest)

    • primum ASD (AVSD)

      • common Trisomy 21
    • sinus venosus (near SVC juntion)

  • largely asymptomatic in childhood

  • symptoms often 4th decade and beyond

    • heart failure

    • atrial arrhythmia

  • signs

    • RV overload

    • ESM in pulmonary region

    • fixed splitting S2

  • needs closure

    • usually by 5

    • AVSD in infancy

    • surgical/percutaneous

Patent ductus arteriosus

Tetralogy of Fallot

  • features

    • VSD

    • overriding aorta

    • right ventricular hypertrophy

  • primary repair before later repair

Transposition of great arteries

  • ventriculo-arterial discordance

  • parallel circulation
