Left ventricular free wall rupture: A real nightmare
1Department of Cardiothoracic Surgery, Faculty of Medicine, University of Coimbra, Coimbra, Portugal.
Abstract:
Left ventricular free wall rupture (LVFWR) is a rarest but often lethal mechanical complication of acute myocardial infarction (AMI). The mortality rate for LVFWR is described from 75% to 90% and it is the cause for 20% of in-hospital deaths after AMI. Death results essentially from the limited time available for emergent intervention after onset of symptoms. Emergency surgery is indicated and normally the rupture site is easily identified, but it may not be apparent macroscopically, corresponding to transmyocardial or subepicardial dissection with an external rupture far from the infarction site, or already thrombosed and contained. Repair of the ventricular wall is usually achieved either by suturing the edges of the tear or closing it with patches of artificial material or biological tissues, usually using some kind of biological glue. However, several cases of successful conservative management have been described. In this Editorial, I comment on the metanalysis conducted by Matteucci et al, published in this issue of the Journal, including 11 nonrandomized studies and enrolling a total of 363 patients, which brings a great deal of new knowledge that can help not only in the prevention but also in the management of this dreadful complication of AMI.
Insights
Left ventricular free wall rupture (LVFWR), a lethal complication of acute myocardial infarction (AMI), has high mortality. A new meta-analysis offers insights into preventing and managing this critical cardiac event.
Area of Science:
- Cardiology
- Cardiac Surgery
- Critical Care Medicine
Background:
- Left ventricular free wall rupture (LVFWR) is a rare but frequently fatal mechanical complication following acute myocardial infarction (AMI).
- Mortality rates for LVFWR range from 75% to 90%, accounting for 20% of in-hospital deaths post-AMI.
- Limited time for intervention after symptom onset is a primary driver of mortality.
Purpose of the Study:
- To comment on a meta-analysis by Matteucci et al. concerning LVFWR.
- To provide new knowledge for the prevention and management of LVFWR.
- To discuss the complexities in identifying and repairing LVFWR sites.
Main Methods:
- Commentary on a meta-analysis of 11 nonrandomized studies.
- Inclusion of data from 363 patients with LVFWR.
- Review of surgical and conservative management strategies.
Main Results:
- The meta-analysis provides significant new insights into LVFWR.
- Discusses challenges in macroscopic identification of rupture sites.
- Highlights successful conservative management cases alongside standard surgical repair.
Conclusions:
- The meta-analysis offers valuable information for clinicians managing LVFWR.
- Emphasizes the need for improved strategies in preventing and treating this complication.
- Underscores the potential for conservative management in select cases.
