Right ventricular tissue Doppler parameters in a patient with massive pulmonary embolus.

We present right ventricular tissue Doppler findings in a 41-year-old man with pelvic fracture who had a near-fatal pulmonary embolus. We found small early systolic lengthening and reduced delayed systolic shortening using strain and strain rate imaging. There were also delayed and fused diastolic waves. Normal systolic tricuspid annular velocities were absent and there was only one late tricuspid annular ascent velocity. Strain, strain rate, and tricuspid annular velocities were normalized early after surgical embolectomy.
