A woman in her 60s had 4 months of malaise, fatigue, dyspnoea, night sweats and grade 3 clubbing. She had a pansystolic murmur and signs of congestive heart failure. Multimodal imaging with a transthoracic echocardiogram, transoesophageal echocardiogram and CT was carried out to diagnose and reconstruct the mass for surgical planning.
