EACVI Club 35 Committee member



  • 68 year-old woman with arterial hypertension and no other history of cardiovascular disease
  • Due to ECG changes (repolarization abnormalities) she is referred to EchoCG

Clinical case information

EKG member leads EKG precordial leads
A tumor mass is seen between left atrium and left ventricle, with an echo-density somewhat greater than that of the myocardium The mass is moving in and out of plane on the parasternal long axis view and seems attached to the mitral valve


The inflow through the mitral valve is not impeded
There is minimal mitral regurgitation
The mass measures around 22/18 mm
Looks situated at the base of the posterior mitral valve leafle
Anterior and apical part of posterior mitral valve leaftets seem intact The movement of the tumor mass is concordant with the movement of mitral valve ring
The mass is not infiltrating atrial or ventricular myocardium



  • A clinical decision was made for this patient to be sent to cardiac surgery
  • Coronary angiography showed no significant coronary artery lesions
  • Surgery findings:
    • At the base of posterior mitral valve leaflet aprominent formation with yellow color was found
    • After opening it 3 ml necrotic material was aspirated leaving a cavity 25/15 mm
    • Mitral valvuloplasty was performed
  • Final histological diagnosis: Old abscess cavity
