Optimal left atrial pressure reduction according to imaging–anatomic composite score. Echocardiographic imaging–anatomic composite score was associated with the likelihood of successful left atrial pressure reduction postprocedure (P=0.0001). A score of 2 points was assigned for a flail scallop, a score of 2 points was assigned for a single regurgitant jet, and a score of 3 points was assigned for optimal 3‐dimensional echocardiographic image quality in proportion to their adjusted risk ratios. Optimal left atrial pressure reduction was not observed in patients with a score of 0 to 2 (n=17). By contrast, 56% of patients with all 3 favorable characteristics achieved optimal left atrial pressure reduction (score >5, n=27). Patients with a score of 3 to 5 had intermediate likelihood of optimal left atrial pressure reduction.
