CLINICAL INTRODUCTION: A woman in her 80s with a medical history of uncontrolled hypertension, hyperlipidaemia and diet-controlled pre-diabetes presented to a primary care physician’s office with fatigue and dyspnoea on exertion of 2–3 months’ duration.

QUESTION: Which of the following explains the pulmonary vein pulsed wave Doppler flow signal, as shown in figure 1?
A. Blunting of systolic flow due to severe mitral regurgitation
B. Atrioventricular conduction block
C. Normal Doppler flow pattern
D. Restrictive diastolic filling of the left ventricle
