RESUMEN
Ventricular septal rupture (VSR) is a rare but highly lethal (â¼60%) mechanical complication of myocardial infarction (MI). Although surgical repair has been the gold standard to correct the structural anomaly, percutaneous closure of the defect may represent a valuable therapeutic alternative, with the advantage of immediate shunt reduction to prevent further hemodynamic deterioration in patients with prohibitive surgical risk. Nonetheless, catheter-based VSR closure has faced certain drawbacks that have hampered its application. We describe a clinical case of postinfarction VSR treated with a percutaneous closure device and discuss the procedure's failure mechanism. (Level of Difficulty: Intermediate.).
RESUMEN
ST-segment elevation in aVR has traditionally been used for electrocardiographic identification of left main coronary artery (LM) myocardial infarction. We present two ST-segment elevation myocardial infarction (STEMI) cases with acute total occlusion of the LM without aVR ST-segment elevation. This report reviews the different electrocardiographic discriminators suggestive of unprotected LM STEMI. (Level of Difficulty: Intermediate.).
RESUMEN
Intramural coronary hematoma (IMCH) is a rare cause of acute myocardial infarction (MI). We aim to review the current knowledge and share our experience with the diagnosis and management of a patient presenting with traumatic IMCH leading to an acute ST-segment elevation MI.
