Non-painful, innocuous and atraumatic technique essential for the study of cardiac functionality. It consists of performing an ultrasound of the heart structures (chambers, valves, muscles, pericardium and blood vessels) and allows us to detect both congenital anomalies and degenerative, tumor or traumatic processes as well as diagnose cardiac pathologies and their staging. This technique allows us to establish treatments and monitor the evolution of pathologies over time.
