Linksventrikuläre Funktionsdiagnostik

Zusammenfassung

Die Analyse der linksventrikulären (LV) Funktion ist eine der Hauptaufgaben in der Echokardiografie und hat entscheidende Bedeutung für Therapieentscheidungen (medikamentös, chirurgisch/interventionell, Device-Implantation) und Prognose. Aus diesen Gründen ist sie Bestandteil jeder echokardiografischen Evaluation. Seit den Anfängen mittels M-Mode hat die Methode eine Entwicklung mit Implementierung neuer Technologien wie 2-D- und 3-D-Echokardiografie und Doppler- sowie zuletzt Mustererkennungs-basierte Strainanalyse genommen. So wird eine exaktere Quantifizierung der LV-Funktion ermöglicht, die die Therapiesteuerung mittels Echokardiografie verbessert. Hier wird die aktuelle echokardiografische Evaluation der systolischen und diastolischen LV-Funktion dargestellt.

Abstract

Analysis of left ventricular (LV) function is a cornerstone of echocardiography with substantial impact on therapy (medical, surgical/interventional, device implantation) and prognosis. Therefore, this assessment is part of every routine echocardiography exam. Since the first attempts using M-Mode, technical and methodological improvements resulted in the implementation of 2D and 3D technology, and doppler- or speckle tracking-based strain analyses. These approaches allow an exact quantification of LV function and improve echocardiography-based guiding of therapy. This article reviews the state-of-the-art evaluation of systolic and diastolic LV function.

Was ist wichtig?
