RESUMO
Thoracic aortic diseases contribute to a major part of cardiac surgeries. The severity of pathologies varies significantly from emergency and life-threatening to conservatively managed conditions. Life-threatening conditions include type A aortic dissection and rupture. Aortic aneurysm is an example of a conservatively managed condition. Pathologies that affect the arterial wall can have a profound impact on the presentation of such cases. Several risk factors have been identified that increase the risk of emergency presentations such as connective tissue disease, hypertension, and vasculitis. The understanding of aortic pathologies is essential to improve management and clinical outcomes.

OBJECTIVE: The Cor-Knot automated fastener has been used to eliminate the need for manual knot-tying in cardiac valve surgery for over a decade. We review the current literature pertaining to Cor-Knot and discuss its benefits and shortcomings with respect to cardiac valve surgery. METHODS: A comprehensive literature search was conducted to identify articles discussing the use of automated fasteners and manually tied knots in the setting of cardiac valve surgery. The search terms used were "heart", "valve surgery", "cardiac", "Cor-Knot", "fastener", "automated fastener", "aortic valve", "mitral valve", "minimally invasive", and "titanium". These terms were used as keywords and, in combination, as MeSH terms to maximize the output of literature searches. Twenty-four relevant articles were identified and reviewed. RESULTS: Current literature provides evidence to support the role of Cor-Knot in facilitating enhanced intraoperative efficacy by reducing total operation times as compared with manual knot-tying. However, studies to date fail to provide evidence for the translation of these intraoperative advantages into improved patient outcomes. Moreover, Cor-Knot is associated with a significant financial burden. CONCLUSION: A plethora of evidence exists to support the intraoperative advantages provided by Cor-Knot. However, the literature is yet to support its role in facilitating superior clinical outcomes as compared with manual knot tying. Larger high-quality trials and studies are required to provide evidence supporting the ongoing use of Cor-Knot in valve surgery.
