Abstract
Background
Minimally invasive surgery (MIS) is a rising trend in medicine, having been adopted into nearly every medical field.
Rather than single approach, Minimally Invasive Mitral Valve Surgery (MIMVS) refers to a collection of techniques and operation-specific technologies such as modified perfusion and visualization techniques that are directed toward minimizing surgical access and trauma.
The aortic occlusion has been extensively reviewed by two techniques in the literature; transthoracic clamp (TTC) and Endo-aortic balloon occlusion (EABO).
Methods
Nine electronic databases were screened for published observational studies comparing EndoAortic (EABO) versus Transthoracic (TTC) for aortic occlusion during MIMVS. Furthermore, the titles and abstracts of the studies resulted from the search were screened for the inclusion in the systematic review and the meta-analysis based on the inclusion and exclusion criteria. Subsequently, the intraoperative data including cross-clamp time, bypass time, conversion, dissection, were extracted. Moreover, the postoperative data including 30 days mortality rate, stroke occurrence, minor neurological events, re-exploration for bleeding, blood transfusion, post hospital ICU stay, post hospital stay, wound infection, recurrence of the mitral valve lesion, respiratory failure, renal failure, myocardial infarction, major vascular complication, and groin lymphocele.
Results
The current meta-analysis highlights the comparative safety of the two most commonly employed aortic clamping techniques for small thoracotomy Mitral Valve Surgeries, TTC, and Endo-aortic clamp. By inclusion of 23 studies with 8829 patients, it represents the largest database on the direct comparison of these two devices ever analyzed.
EABO approach was associated with a trend toward longer cross-clamp, CPB time, postoperative hospital stay and a higher risk of intraoperative aortic dissection.
Conclusion
Our meta-analysis demonstrated that patients undergoing EABO may experience slightly more risk of occurrence of intraoperative aortic dissection, longer bypass time and cross clamp time and longer postoperative hospital stay.
