Day 1	Admission to the emergency department for acute heart failure, evidence of bi-atrial masses at the urgent ultrasound scan.
Day 2	Transthoracic echocardiography: confirmation of bi-atrial masses.
Day 3	Transoesophageal echocardiography: vacuolated and inhomogeneous areas, cardiac myxomas are suspected.
Day 5	Computed tomography evaluation: morphologically compatible with myxomas, but they did not enhance iodine contrast agent as a typical thrombus behaviour.
Day 6	Contrast echocardiography: mild late contrast enhancement of left atrial mass suggesting the diagnostic hypothesis of bilateral myxomas.
Day 9	Surgical resection: inspection of the masses was suggestive for neoplastic origin.
Day 11	Histological examination: aspect of vascularized thrombotic material.
