Hoge frequentie Doppler-echografie is een nieuwe technologie voor de beoordeling van regionale myocardiale functie. Dit werk presenteert eerste bewijs waaruit de toepasselijkheid van deze veelzijdige imaging platform voor de herhaalde meting van het myocard stam, dp / dt, en mitralisinsufficiëntie in de ischemie-reperfusie (IR) muizen hart.
