Diagnosis Of Free Wall Rupture Research Articles

Syncope and undifferentiated shock.

Ventricular free wall rupture is a rare post myocardial complication with a high associated mortality. In this article we discuss the case of an elderly patient who presented to our emergency department in shock after an episode of syncope. Using Point Of Care Ultrasound (POCUS), identification of cardiac tamponade and pericardial thrombus was possible, signs indicating a diagnosis of free wall rupture. Early initiation of transfer proceedings to a tertiary cardio-thoracic unit was therefore possible, resulting in a positive patient outcome.

Role of contrast-enhanced magnetic resonance imaging in detecting early adverse remodeling and subacute ventricular wall rupture complicating myocardial infarction

Ventricular free wall rupture is a catastrophic complication of acute myocardial infarction accounting for a significant proportion of in-patient deaths. Various imaging modalities including two-dimensional and contrast echocardiography have been applied for the early diagnosis of free wall rupture. Cardiac magnetic resonance imaging has recently gained favor as a tool providing accurate diagnosis and visualization of the site of rupture to enable planned surgery. We present a case of subacute free wall rupture where contrast enhanced myocardial resonance imaging helped to delineate the location and extent of the myocardial tear, thereby prompting appropriate surgical intervention.

Primary angioplasty reduces the risk of left ventricular free wall rupture compared with thrombolysis in patients with acute myocardial infarction

ObjectivesThis study aimed to evaluate the effect of primary angioplasty (PA) over the risk of free wall rupture (FWR) in reperfused acute myocardial infarction (AMI). BackgroundIt has been suggested that PA reduces the risk of FWR compared with thrombolysis. However, few studies have evaluated this issue, and there are no data demonstrating this hypothesis. MethodsA total of 1,375 patients with AMI treated with PA (n = 762, 55.4%) or thrombolysis (n = 613, 44.6%) within 12 h after symptoms onset were included. The diagnosis of FWR was made either in the presence of sudden death due to electromechanical dissociation with large pericardial effusion on an echocardiogram or when demonstrated post mortem or at surgery. A multivariable analysis was performed including type of reperfusion strategy. ResultsThe overall incidence of FWR was 2.5% (n = 34): 1.8% and 3.3% in patients treated with PA and with thrombolysis, respectively (p = 0.686). The following characteristics were associated with a higher rate of FWR in the univariable analysis: age >70 (5.2% vs. 1.2%, p < 0.001), female gender (5.1% vs. 1.8%, p = 0.006), anterior location (3.3% vs. 1.4%, p = 0.020) and treatment >2 h after symptoms onset (3.6% vs. 1.7%, p = 0.043). In the multivariable analysis, age >70 (odds ratio [OR]: 4.12, 95% confidence interval [CI]: 2.04 to 8.62, p < 0.001) and anterior location (OR: 2.91, 95% CI: 1.36 to 6.63, p = 0.008) were independent risk factors of FWR, whereas treatment with PA was an independent protective factor (OR: 0.46, 95% CI: 0.22 to 0.96, p = 0.0371). ConclusionsIn patients with AMI, PA reduces the risk of FWR in comparison with thrombolysis.
