Overview

Retrospective analysis reveals consistent left ventricular mass in healthy individuals and heart failure patients, highlighting ECG-gated imaging potential.

Key Points

  • Time-resolved ventricular cines were effectively constructed from real-time exercise-CMR, demonstrating promising utility.
  • Consistency of left ventricular mass between rest and exercise was maintained, with bias around 1.5 g for healthy volunteers at end diastole.
  • The methodology involved semi-automatic construction of time-resolved cines by synchronizing R-R intervals across slice positions.
  • These findings underscore the potential of real-time exercise-CMR in assessing cardiac function, particularly in heart failure patients.
