An 84-year-old man presented urgently to the cardiology clinic with rapid onset exertional dyspnoea while walking on the flat. Five months previously, he underwent implantation of a balloon-expandable 26 mm transcatheter heart valve (SAPIEN 3, Edwards Lifesciences) for severe aortic stenosis. On clinical examination, the jugular venous pressure was elevated and a mid-late ejection systolic murmur was audible in the aortic region. ECG demonstrated sinus rhythm with a left ventricular (LV) strain pattern. Transthoracic echocardiography and cardiac CT were performed (figure 1).
