Background Τhe influence of atrial septal occluders in left atrial ( LA ) function after percutaneous closure of patent foramen ovale ( PFO ) has not been thoroughly studied. Methods Twenty‐five patients (mean age 40.7 ± 12 years) undergoing percutaneous PFO closure were enrolled in this study. Transthoracic echocardiogram ( TTE ) was performed 3 and 6 months before the procedure. Volumetric indices (active emptying fraction: LA AEF , expansion index: LA EI , and passive emptying fraction: LA PEF ), strain and strain rate ( SR ), were calculated during the contractile, reservoir, and conduit LA phases for the lateral, anterior, and inferior LA walls with TTE . Results After 3 months, a decrease in the SR of the LA anterior wall was observed (from 2.12 ± 0.22 to 1.66 ± 0.26, P < 0.045), while the LA lateral wall strain was found to be increased (from 0.708 ± 0.15 to 0.783 ± 0.159, P < 0.001). Moreover, simultaneously LA AEF was greater compared with baseline (from 31.0 ± 1.6 to 34.0 ± 1.6, P < 0.004). However, all these alterations reversed at 6 months. Conclusions Segmental LA function is altered transiently after percutaneous PFO closure with a septal occlude. The LA anterior wall SR decreases, while the lateral wall strain increases. The impact of these alterations needs further clarification.
