Acute Changes in LV Function as Assessed by Strain and Myocardial Performance Index (MPI) in Post Tricuspid Shunts Following Closure

Lakshmi Sadasivan Pillai¹

Abstract: Background: Hemodynamically significant left to right shunts, once closed, decreases the left ventricular (LV) preload and increases the after load by isolating the low resistance pulmonary circulation from LV outflow circulation. The simultaneous reduction in the LV preload and increase in after load

Background: Patent ductus arteriosus (PDA) closure results in a sudden drop in left ventricular (LV) preload, and this may affect the LV functions. Aim: The aim was to evaluate the immediate- and short-term changes in LV functions by speckle tracking echocardiography (STE) post percutaneous PDA closure. Materials and Methods: The study included 45 patients with PDA who were referred for PDA trans-catheter closure. All the patients included in the study underwent full echocardiographic examination and speckle tracking analysis before PDA closure, immediately after closure, and 1 month after the PDA closure. Results: There was no statistically significant change in LV functions by two-dimensional transthoracic echocardiography; the LV end-diastolic volume (EDV) decreased significantly in the immediate follow-up from 41.608 ± 25.8846 ml before duct closure to 36.317 ± 21.6945 ml. The drop in the LV EDV continued in the 1-month follow-up. The LV end-systolic volume decreased as well, however it took 1 month for this drop to be statistically significant. The LV end-diastolic dimension also decreased significantly after duct closure. Regarding STE results, the global LV strain and strain rate values did not significantly change. The global strain values had a mean of −22.944% ± 3.5128% before duct closure and decreased to a mean −22.028% ± 2.8932% immediately after duct closure. Conclusion: The study concluded that STE could be used to detect subtle changes in LV deformation. Time to peak systolic strain is an understudied parameter that needs further evaluation to provide a better understanding regarding its role in myocardial function assessment.
