Abstract: BACKGROUND: The aim of this study was to assess speckle tracking-derived fetal cardiac function in a normal population and in recipient fetuses of twin-to-twin transfusion syndrome (TTTS). METHODS: A case-control study was conducted of 59 uncomplicated singleton pregnancies and 17 recipient fetuses of TTTS. Peak systolic strain, strain rate, velocity, and displacement were calculated, corrected for gestational age, and compared between patients with TTTS and controls. RESULTS: The feasibility of speckle tracking was 83% in controls but only 61% in patients with TTTS. Myocardial velocity and displacement increased over gestation, and regional differences were present within each wall and between walls. Strain and strain rate were stable within each wall but were higher in the right ventricle than in the left ventricle and septum. Right ventricular strain was decreased in patients with TTTS compared with controls (0.75 +/- 0.34 vs 1.00 +/- 0.37 multiples of the median, P = .04). CONCLUSION: The feasibility of speckle tracking is low when imaging conditions are challenging, but it can identify right ventricular failure in selected patients with TTTS.
