Left ventricular wall rupture. In patients with acute myocardial infarction left ventricular free wall rupture is an infrequent complication 24 but it is associated with a high mortality from pericardial tamponade1-8 It accounts for 524 of all in hospital deaths related to acute myocardial infarction4 6 9 10 To reduce this high mortality it is important to improve the way in which these patients are. Left Ventricular Rupture Left ventricular LV rupture is a catastrophic but a common occurrence with acute myocardial infarction patients. Incidence of LV free-wall rupture post-acute myocardial infarction AMI is less than 1 but mortality is extremely high.
Left ventricular rupture is rarely described in myocardial infarction with nonobstructive coronary arteries MINOCA. In our patient imaging and intraoperative findings support the hypothesis that coronary vasospasm determined myocardial necrosis followed by LV free wall rupture. Pericardial adhesions and prompt cardiac surgery prevented cardiac tamponade.
Transthoracic echocardiogram could not clearly identify a free-wall rupture so a left ventricular angiogram was performed and showed evidence of a posterobasal inferior wall rupture with double density in the right and trabeculated appearance in the left anterior oblique views attributed to extravasated and clotted blood in the pericardium Figure 2C and 2D and Movies I. Left ventricular free wall rupture after myocardial infarction. Still a challenging complication.

During emergency coronary angiography his condition became hemodynamically unstable. Left ventriculography shown in a video revealed rupture of the left ventricular free wall. Left ventricular free wall rupture LVFWR is a fearful complication of acute myocardial infarction in which a swift diagnosis and emergency surgery can be crucial for successful treatment.
Because a significant number of cases occur subacutely clinicians should be aware of the risk factors clinical features and diagnostic criteria of this complication. An autopsy revealed mainly hemopericardium 150 ml due to 2 mm wide rupture in apical segment of the left ventricle free wall. Another tiny rupture was identified in apical part of interventricular septum and in trabecular part of the muscle.
There were atherosclerotic changes with stenosis up to 50 inside coronary arteries. Left ventricular free wall rupture LVFWR is a rare and fatal mechanical complication following an acute myocardial infarction AMI. Cases of survival after LVFWR due to ST-segment elevation myocardial infarction STEMI treated with a conservative treatment strategy are extremely rare.
Left ventricular free wall rupture LVFWR is a rare complication after myocardial infarction and usually occurs 1 to 4 days after the infarct. Over the past decade the overall incidence of LVFWR has decreased given the advancements in reperfusion therapies. Rupture of left ventricular free wall complicates the in- hospital course of 23-32 of patients with acute my- mardial infarction and accounts for 126-17 of in- hospital fatalities of acute myocardial infarction.
Risk fac- tors include hypertension no prior myocardial infarction. The left ventricular free-wall rupture is a serious and often lethal complication following an ST elevation myocardial infarction. However very rarely this rupture can be contained by the pericardium forming a pseudoaneurysm.
Left Ventricular Free Wall Rupture Coronal CT of the abdomen and pelvis with intravenous contrast demonstrates an outpouching along the inferior wall of the heart red arrows which represents an acute contained left ventricular free wall rupture. The adjacent myocardium is not enhancing compatible with myocardial infarction. Left ventricular free-wall rupture is one of the most fatal complications after acute myocardial infarction.
Surgical treatment of post-infarction left ventricular free-wall rupture has evolved over time. Direct closure of the ventricular wall defect linear closure and resection of the infarcted m. Left ventricular rupture is usually a fatal complication following MI.
Several autopsy series have accurately defined this entity 1 2. Approximately 4 of myocardial infarctions will develop ventricular free wall rupture 2 3. It accounts for 1221 of deaths following myocardial infarction 2 3.
Following cardiogenic shock and fatal ventricular arrhythmias left ventricular free wall rupture LVFWR is ranked third as the leading cause of all infarct-related deaths. 1 Post infarction LVFWR was first described by William Harvey in 1647 as a finding at autopsy of a knight who suffered severe chest pain. 2 Fitzgibbon reported in 1972 the first successful surgical repair of left.
Left ventricular LV free wall rupture is a catastrophic complication after acute myocardial infarction. The optimal therapeutic strategy is controversial and.
