Abstract:
Objective:To evaluate and compare cardiac structure and function pre- and post-percutaneous interventional treatment of pulmonary hypertension (PH) using echocardiography.
Methods:Eight female patients received percutaneous interventional treatment in our hospital were enrolled. All of them were suffered moderate to severe PH. Echocardiographic parameters included: right ventricular diameter (RVD), left ventricular diameter (LVD), right atrial diameter (RAD), left atrial diameter (LAD), main pulmonary arterial diameter (DMPA), left ventricular eccentric index (EI), left ventricular ejection fraction (LVEF), right ventricular systolic pressure (RVSP), tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RVFAC), tissue Doppler-derived tricuspid lateral annular systolic velocity (s′), right ventricular index of myocardial performance (RIMP) and right ventricular free wall longitudinal strain (RVLSFW). The median time for follow-up after interventional treatment was 98 d.
Results:①In our study, 8 patients had no significant serious complications, and only one patient had mild intimal avulsion during stenting. ②RVSP and RVD/LVD increased significantly before intervention in patients with PH (P<0.05). After interventional treatment, RVSP (P<0.01) and RVD/LVD decreased significantly (P<0.05). ③The result of follow-up showed that RVFAC, RIMP, s′and RVLSFW improved significantly(P<0.05).
Conclusions:Echocardiography could evaluate the recent effect of interventional treatment and illustrates that the interventional treatment for pulmonary artery stenosis is effective and safe.
