CMR strain-rate predicts ventricular tachyarrhythmia

Quint Hagdorn, MD and co-authors from Groningen University Medical Center in the Netherlands under the supervision of Tineke Willems, MD studied a group of 172 patients with repaired tetralogy of Fallot (rTOF) and followed these over a median period of 7.4 years. Patients underwent CMR investigation and and strain and strain-rate of both LV and RV were assesses using Medis’ QStrain. During the FU period, 9 patients (4.5%) experienced the primary endpoint of ventricular tachycardia (VT). The paper is published in the International Journal of Cardiology 2019.

The authors concluded that in patients with rTOF, LV systolic circumferential strain-rate is an independent predictor for the development of VT. On the other hand, ventricular strain parameters did not predict deterioration of ventricular function in the studied population.
