        FRCA questions No previous FRCA question on Peripartum Cardiomyopathy

        Please find example CRQ below

        Cardiomyopathy Example CRQ  a) What are the diagnostic criteria for peripartum cardiomyopathy? (4 marks)

        • Heart failure developing towards the end of pregnancy or up to five months post-partum
        • Absence of another identifiable cause of cardiac failure
        • Absence of cardiac symptoms or disease prior to late pregnancy
        • Left ventricular dysfunction - defined as an ejection fraction less than 45% or reduced fractional shortening of less than 30%

        b) What are the risk factors for peripartum cardiomyopathy? (4 marks)

        • Maternal age >30 yrs
        • Multiparity
        • Ethnic group – e.g. African descent
        • Obesity
        • Multiple pregnancy
        • Pregnancy associated hypertensive disorders
        • Essential hypertension
        • Tocolytic therapy with β-agonists
        • Cocaine use

        c) What are the anaesthetic management aims during labour for a woman with peripartum cardiomyopathy, and how can these be achieved? (12marks)

         Anaesthetic Aims  Management strategies
         Maintain myocardial perfusion  
        - avoid hypotension
        - avoid tachycardia
        - avoid arrhythmia
         Consider invasive blood pressure monitoring
        Smooth induction of general anaesthetic
        Titrated combined spinal epidural technique
        Maintain intravascular volume
        ECG monitoring and early intervention
         Reduce myocardial workload  
         - avoid catecholamine surges  Early epidural
        Opiates to attenuate response to laryngoscopy
        Good intra and post-operative analgesia e.g. Continue epidural post-operatively
         Optimise cardiac output  
        - maintain preload
        - maintain/increase contractility
        - prevent increased afterload/ reduce systemic vascular resistance.
        Consider cardiac output monitoring
        Avoid prolonged Valsalva – consider instrumental second stage of labour
        Neuraxial anaesthesia achieves this better than general anaesthesia
        Avoid aortocaval compression
        Neuraxial anaesthesia
        Try to avoid ergometrine
