Insights
Left ventricular free wall rupture (LVFWR), a fatal heart attack complication, was successfully treated with intra-pericardial thrombin injection. This innovative approach offered a favorable outcome for a patient experiencing LVFWR and cardiac tamponade.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Innovation
Background:
- Left ventricular free wall rupture (LVFWR) is a rare but fatal complication following acute myocardial infarction (MI).
- Existing treatments for LVFWR, including surgical repair and medical management, carry significant risks and variable outcomes.
- Cardiac tamponade frequently complicates LVFWR, necessitating urgent intervention.
Purpose of the Study:
- To present a novel therapeutic approach for managing left ventricular free wall rupture (LVFWR) with cardiac tamponade.
- To evaluate the efficacy and safety of intra-pericardial thrombin injection as a treatment modality for LVFWR.
Main Methods:
- A case report detailing the management of a patient with acute myocardial infarction complicated by LVFWR and cardiac tamponade.
- Administration of intra-pericardial thrombin injection as a minimally invasive therapeutic intervention.
- Monitoring of patient's hemodynamic status and echocardiographic findings post-intervention.
Main Results:
- The intra-pericardial thrombin injection resulted in successful cessation of bleeding and resolution of cardiac tamponade.
- The patient demonstrated a favorable clinical outcome with hemodynamic stability following the procedure.
- No major adverse events or complications were observed during the follow-up period.
Conclusions:
- Intra-pericardial thrombin injection represents a promising and potentially life-saving alternative treatment for left ventricular free wall rupture (LVFWR) with cardiac tamponade.
- This minimally invasive technique may offer a favorable risk-benefit profile compared to traditional surgical interventions.
- Further research and larger studies are warranted to establish the role of thrombin injection in the management of LVFWR.
Abstract:
Left ventricular free wall rupture (LVFWR) is a fatal complication of acute myocardial infarction. Different modalities of treatment were previously described, including surgical intervention and medical treatment. We report a case treated with intra-pericardial thrombin injection that gave a favourable outcome for a patient who presented with LVFWR and cardiac tamponade, following acute myocardial infarction.
