Left ventricular free wall rupture: clinical presentation and ...

In patients with acute myocardial infarction, left ventricular free wall rupture is an infrequent complication (2–4%) but it is associated with a high mortality from pericardial tamponade. 1-8 It accounts for 5–24% of all in hospital deaths related to acute myocardial infarction. 4 6 9 10 To reduce this high mortality it is important to improve the way in which these patients are classified, as this may help clinicians anticipate myocardial rupture, prevent it occurring, and achieve better therapeutic results when it does occur.

Treatment strategies for post-infarction left ventricular free-wall ...

Left ventricular free-wall rupture (LVFWR) may represent a dramatic and life-threatening event, occurring in up to 2% of patients with acute myocardial infarction (AMI).1,2The clinical presentation varies from a catastrophic blowout type characterized by cardiogenic shock and eventually cardiac arrest, to the oozing type with

Left Ventricular Free Wall Rupture in Transmural Myocardial ...

Left ventricular free wall rupture (LVFWR) is a grave complication of acute myocardial infarction (MI). We report a case of a 73-year-old male who developed LVFWR five days after a transmural MI. The diagnosis was confirmed with echocardiography, which showed a large pericardial effusion with a clot in the pericardial sac.
