A new proximal anastomosis technique in two patients with severely calcified aorta

Area of Science:

• Cardiovascular Surgery
• Aortic Disease
• Surgical Techniques

Background:

• A severely calcified aorta presents significant risks, including atheroemboli and bleeding, during cardiac surgery, with reported incidences ranging from 14% to 29%.
• Traditional methods involving aortic cannulation and clamping are associated with elevated risks in these patients.
• The no-touch beating heart technique has emerged as a preferred alternative for managing calcific aorta during cardiac procedures.

Observation:

• This study introduces a specific closed proximal anastomosis technique designed for patients with severely calcified aortas.
• The technique aims to mitigate the risks associated with aortic manipulation in this high-risk cohort.
• It focuses on performing the anastomosis without direct aortic clamping or cannulation.

Findings:

• The presented closed proximal anastomosis technique is a viable option for cardiac surgery in patients with severely calcified aortas.
• This approach potentially reduces the incidence of atheroemboli and bleeding compared to conventional methods.
• It allows for a beating heart procedure, further enhancing patient safety.

Implications:

• This technique offers a promising solution for improving outcomes in a challenging patient population undergoing cardiac surgery.
• It may become a valuable addition to the armamentarium for managing complex aortic disease.
• Further studies are warranted to validate the long-term efficacy and safety of this innovative approach.
