Repeated Catheter Ablation Induced Intra‐atrial Conduction Delay Mimicking Atrial Stiffness Syndrome

F IGURE 1 A, We noted sinus rhythm with P-wave prolongation on 12-lead electrocardiography. B, Atrial wave was absent in the transmitral flow by echocardiography. C, Lateral mitral annular tissue velocity associated with atrial contraction was absent by echocardiography. D, Atrial wave (arrow) was apparent in the trans-tricuspid flow. E, Lateral tricuspid annular tissue velocity associated with atrial contraction (arrow) was apparent. F, Atrial wave (arrow) was detected by pulmonary venous flow on transthoracic echocardiography. G, Atrial wave (arrow) was detected by pulmonary venous flow on transesophageal echocardiography 1 | CASE
