The correct answer is (E) arterio-venous fistula.
High-output heart failure occurs when the heart is unable to meet the body’s increased demand for blood flow, leading to an excessive workload on the heart. Causes of high-output heart failure include:
– Arterio-venous fistula (AVF): an abnormal connection between an artery and a vein, causing increased blood flow and workload on the heart.
– Anemia
– Thyrotoxicosis (hyperthyroidism)
– Paget’s disease
– Beriberi (thiamine deficiency
