A teenager with pectus excavatum was sent to the public clinic for follow-up echocardiography due to previously identified mitral valve prolapse with regurgitation of 1 st, with complaints of rapid fatigue during physical exertion.
On the current ultrasound of the heart, prolapse and regurgitation were not detected, but in the projection of the apex of the heart, free fluid is visualized, presumably in the pericardial cavity, a layer of free fluid in different views up to about 1.5 cm.
Inferior vena cava 16 mm, collapses during breathing less than 50%.
An urgent consultation with a cardiologist was recommended.
