Experience in 100 transthoracic balloon pumps

Area of Science:

• Cardiology
• Cardiothoracic Surgery
• Medical Devices

Background:

• Postoperative cardiogenic shock is a critical complication requiring circulatory support.
• Intraaortic balloon pumps (IABPs) are commonly used for hemodynamic stabilization.
• Ascending aorta access for IABP placement offers an alternative to traditional femoral access.

Purpose of the Study:

• To evaluate the safety and complication rates of transthoracic intraaortic balloon pump (IABP) placement.
• To compare complication rates with expected rates in high-risk patients undergoing IABP therapy.
• To assess the utility of the transthoracic route for IABP introduction.

Main Methods:

• Retrospective review of 100 consecutive patients receiving transthoracic IABP for postoperative cardiogenic shock.
• Evaluation of complication rates in 81 patients who survived IABP removal.
• Analysis of specific complications including balloon rupture, cerebrovascular accident, transient ischemic attack, bleeding, and mediastinitis.

Main Results:

• Complications potentially related to transthoracic IABP included balloon rupture (6.2%), cerebrovascular accident (2.5%), transient ischemic attack (1.2%), bleeding at arteriotomy site (3.7%), and mediastinitis (3.7%).
• Balloon rupture and mediastinal bleeding rates appeared increased compared to expected rates.
• Neurologic event and mediastinal infection rates did not appear elevated.

Conclusions:

• Transthoracic IABP placement may increase risks of balloon rupture and mediastinal bleeding.
• This approach avoids lower extremity ischemic complications associated with femoral access.
• Transthoracic IABP insertion is a viable and useful route for managing cardiogenic shock.
