A 72-year-old man with an ejection fraction of 25% is scheduled to undergo elective coronary artery bypass graft using cardiopulmonary bypass. Because of the high-risk nature of the operation, the surgeon wants to insert an intraaortic balloon pump (IABP) before initiating cardiopulmonary bypass. An intraoperative transesophageal echocardiogram (TEE) is requested to ensure correct placement.

Intraaortic Balloon Pump Counterpulsation, Part I: History, Technical Aspects, Physiologic Effects, Contraindications, Medical Applications/Outcomes

TLDR
The history of the development of counterpulsation, technical considerations, and complications associated with its use, its physiologic effects, and evidence for its use in myocardial ischemia and cardiogenic shock are focused on.

Resuscitative Endovascular Balloon Occlusion of the Aorta: Principles, Initial Clinical Experience, and Considerations for the Anesthesiologist

TLDR
Suggestions and recommendations for intraoperative management are made based on extrapolation from initial surgical-based reports, opinions from a team with increasing experience, and translated experience from emergency aortic vascular surgical procedures to conclusively guide anesthetic management.

A Narrative Review of the 2020 Guidelines for Use of Transesophageal Echocardiography to Assist with Surgical Decision- Making by the Cardiac Anesthesiologist in the Operating Room.

TLDR
A narrative review focuses and expands upon the relevant portions for the cardiac anesthesiologist for conducting a TEE examination for different cardiac surgeries and for using the information obtained to interpret and to communicate findings to the surgical team.

Transesophageal Echocardiography: Guidelines for Point‐of‐Care Applications in Cardiac Arrest Resuscitation

Transesophageal echocardiography in the emergency department: A comprehensive guide for acquisition, implementation, and quality assurance

TLDR
This paper serves to provide an updated and in‐depth description of these processes to assist with the initiation of such a program, including a detailed discussion of budgetary considerations, physician credentialing, and device use and maintenance protocols.

Influence of Aortic Outflow Cannula Orientation on Epiaortic Flow Pattern During Pulsed Cardiopulmonary Bypass

TLDR
Pulsed CPB may reduce brain damage during heart surgery, so the evaluation of epiaortic flow during the extracorporeal circulation with various arterial cannula orientations is useful for the analysis of hemodynamic modifications.

Intraoperative transesophageal echocardiography to assist the insertion and positioning of the intraaortic balloon pump.

TLDR
Because of its ability to image the thoracic aorta in real time, transesophageal echocardiography (TEE) is very useful in inserting and positioning the IABP during surgery.

Visceral Arterial Compromise During Intra-Aortic Balloon Counterpulsation Therapy

TLDR
IABP malposition was commonly identified by CT and reasons included incorrect proximal balloon position as well as an anatomic-to-balloon length mismatch, which meant shorter than recommended balloon sizes and better positioning strategies had to be considered.

Basic Principles of the Intraaortic Balloon Pump and Mechanisms Affecting Its Performance

TLDR
The basic disciplines of counterpulsation by IABP and the induced hemodynamic changes while clarifying the biologic mechanisms that play a crucial role in the modification of IABp acute hemodynamic performance are described.

The Carina as a Useful Radiographic Landmark for Positioning the Intraaortic Balloon Pump

TLDR
In 16% of patients, the IABP was too close to the LSCA origin when it was placed at the aortic knob, whereas positioning the I ABP at 2 cm above the carina provided an adequate position for the IabP tip.

Preoperative Intra‐Aortic Balloon Pump in Patients Undergoing Coronary Bypass Surgery: A Systematic Review and Meta‐Analysis

TLDR
Evidence from this meta‐analysis support the use of preoperative IABP in high‐risk patients to reduce hospital mortality and most of these complications improved after discontinuation of IABp.

Practice Guidelines for Perioperative Transesophageal Echocardiography

TLDR
This update includes data published since the Practice Guidelines for Perioperative Transesophageal Echocardiography were adopted by the ASA and the Society of Cardiovascular Anesthesiologists in 1995 and published in 1996.
