Zusammenfassung
Die Magnetresonanztomographie ermöglicht es, sowohl die Klappenmorphologie als auch die Flussgeschwindigkeit über eine Klappe darzustellen. Mit dieser Technik können der Echokardiographie entsprechende Befunde erhoben werden; die Visualisierung der Klappen selbst gelingt zur Zeit allerdings meist besser mit der Echokardiographie. Die Vorteile der Magnetresonanztomographie liegen in der Quantifizierung von Flussvolumina und der Möglichkeit, Insuffizienzen durch den Vergleich von rechts- und linksventrikulären Schlagvolumina zu quantifizieren. Dies gelingt allerdings nur bei Befall lediglich einer Herzklappe. Der folgende Text bezieht sich weitgehend auf chronische Klappenerkrankungen.
