[Post-infarction anterior septal rupture. Aspects of the IVC flux on bidimensional Doppler with color coding].
In a case of anterior septal rupture complicating a transeptal myocardial infarction, the diagnosis of IVC is immediately confirmed by bidimensional Doppler with color coding. The abnormal flow and its three components are studied in multiple section planes. Incidences permitting the best visualization of the shunt are the longitudinal sections: left parasternal and apical-long axis. The parasternal short axis section only visualizes an abnormal intraventricular flow. Sweeping of the septum by caudal tilting of the probe, from an apical section of the 4 cavities, successively studies the three portions: left intraventricular, trans-septal, and right intraventricular of the abnormal flow. The size of the defect seems underestimated on bidimensional ultrasonograms as well as color Doppler. Speed, sensitivity and reliability of the color coded bidimensional Doppler, places it as the reference diagnostic test in this type of pathology. Catheterization still has a place in evaluating the severity of the shunt.
