A 62-year-old woman presented herself to the Cardiology Department with a 3-month history of repeated episodes of sudden-onset palpitations and dizziness. Physical examination revealed a 2/6 holosystolic murmur at the apex. ECGs showed frequent premature ventricular contractions (PVCs). On Holter ECG monitoring, PVCs accounted for 21.9% of all heart beats and an episode of non-sustained ventricular tachycardia was recorded. Transthoracic echocardiography showed a dilated left atrium, moderate mitral regurgitation and preserved left ventricular (LV) function. Cardiac CT revealed normal structured epicardial coronary arteries. Further, pulmonary CT scan (figure 1A) and cardiac MRI (cMRI) (figure 1B …
