Abstract | OBJECTIVE: METHODS: Patients who underwent PEA with preoperative and postoperative transthoracic echocardiograms at our center between June 2010 and July 2019 were retrospectively reviewed. The composite end point was defined as death or hospitalization due to worsening heart failure, bleeding, or recurrent pulmonary embolism. RESULTS: In total, 158 patients were included for analysis. Right ventricular basal (48 [45-52] vs 43 [39-47] mm, P < .001), midcavitary (46 [42-50] vs 38 [34-42] mm, P < .001), and longitudinal dimensions (87 [83-93] vs 80 [75-84] mm, P < .001), along with the right atrial volume index (37 [25-51] vs 24 [18-34] mL/m2, P < .001), significantly decreased, whereas left ventricular and atrial sizes and left ventricular ejection fraction increased after PEA. Overall, 78 patients (49%) showed significant TR on preoperative transthoracic echocardiograms, and 33 (21%) had significant residual TR after PEA. Fourteen patients died, and 24 patients met the composite end point. Residual TR after PEA was independently associated with mortality (P = .005) and the composite end point (P = .003). Patients with residual TR had significantly worse survival (log-rank P < .001) and greater event rates (log-rank P = .003) than those without residual TR. CONCLUSIONS: Significant improvements in right heart remodeling were seen following PEA. However, residual TR was a poor prognostic marker.
