Intra-aortic balloon assist: initial Mayo Clinic experience and current concepts
Insights
Intra-aortic balloon assist (IABA) shows hemodynamic improvement in critically ill patients, but initial high complication rates led to technique modifications. Experience has evolved, enabling less reluctant use of this cardiac-assist modality.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Critical Care Medicine
Background:
- Intra-aortic balloon assist (IABA) is a cardiac-assist modality.
- Initial use of IABA in critically ill patients presents challenges.
Purpose of the Study:
- To report the initial experience with IABA at Mayo Clinic.
- To describe the evolution of IABA techniques, patient selection, and applications.
Main Methods:
- Retrospective review of 34 patients receiving IABA.
- Analysis of hemodynamic data and complication rates.
- Literature review to inform technique modifications.
Main Results:
- 17 out of 34 patients survived hospitalization.
- Documented hemodynamic improvement was observed with IABA.
- An initial complication rate of 26% necessitated technique modifications.
Conclusions:
- IABA can provide hemodynamic support in critically ill patients.
- Modifications in technique and patient selection have improved IABA utilization.
- Experience has led to a less reluctant application of IABA as a cardiac-assist modality.
Abstract:
The initial experience with intra-aortic balloon assist (IABA) at the Mayo Clinic has been with 34 desperately ill individuals; 17 survived hospitalization. Hemodynamic improvement associated with institution of IABA can be documented. An unacceptably high complication rate (26%) has resulted in extensive modification in the technique of employing IABA. Concepts of patient selection and applications of IABA have evolved from this initial experience and from a review of the literature and have resulted in less reluctant use of this cardiac-assist modality.
