Pseudo dilated cardiomyopathy: Dilated cardiomyopathy-like changes due to a combination of stuck mechanical mitral valve and coronary microvascular dysfunction-An autopsy case.

Thrombus formation in the microvessels and endocardium was suggestive of endothelial cell damage, myocardial ischemia, and a decreased coronary flow reserve. Sustained pulmonary hypertension due to thrombosis worsened the biventricular dysfunction.

The importance of pre-ablation atrial septal evaluation for a patient with surgical patch closure history.

Limited studies report on the status of surgical closure patches for atrial septal defect (ASD) in the remote period. In our case, transthoracic echocardiography revealed a fistula of ASD patch before pulmonary vein isolation for atrial fibrillation. Preoperative Imaging examinations aid in evaluating the effect of the needle puncture around the artificial material of the atrial septum and catheter manipulation for patients with a history of ASD closure.
