Intra-aortic balloon counterpulsation via the ascending aorta

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Thoracic Surgery

Background:

• Intra-aortic balloon pumps (IABP) are crucial for hemodynamic support.
• Traditional IABP insertion methods can be invasive and carry risks.
• Exploring safer and more direct insertion techniques is essential.

Purpose of the Study:

• To evaluate the safety and efficacy of direct intra-aortic balloon insertion via the ascending aorta.
• To assess the feasibility of this technique in both operating room and surgical intensive care unit settings.

Main Methods:

• Twenty-three patients underwent direct insertion of intra-aortic balloons into the ascending aorta.
• Concentric purse-string sutures were used for direct aortic access.
• Repeat explorations allowed for safe balloon removal and bypass graft assessment.

Main Results:

• The procedure was performed in 21 patients in the operating room and 2 in the surgical intensive care unit.
• Only one patient experienced adverse sequelae.
• Thirteen patients achieved long-term survival, ranging from one month to four years.

Conclusions:

• Direct intra-aortic balloon insertion via the ascending aorta is a safe and effective technique.
• This method offers advantages for hemodynamic support and allows for graft inspection.
• The procedure demonstrates a favorable safety profile and contributes to positive patient outcomes.
