A 6-Year Single-Center Experience of Intra-aortic Balloon Pump Treatment—Retrospective Analysis of 223 Patients

Analysis of risk factors for in-hospital mortality in 177 patients who underwent isolated coronary bypass grafting and received intra aortic balloon pump

BACKGROUND AND AIM OF THE STUDY

Intra-aortic balloon pump (IABP) is the most commonly used device for circulatory support of patients with heart disease. The aim of this study evaluated the risk factors for outcomes of patients who underwent isolated coronary bypass grafting and received IABP.

METHODS

One hundred-seventy-seven patients underwent isolated coronary bypass grafting and received intraoperative IABP. All perioperative data were recorded. The primary end-point was in-hospital mortality, while the secondary end-points were the length of intensive care unit (ICU) stay and hospital length of stay (LOS).

RESULTS

In-hospital mortality was 5.6% (10 patients). Multivariable logistic regression analysis showed that the risk factors for in-hospital mortality were preoperative plasma creatinine level and cardiopulmonary bypass (CPB) time (for both p < .05). Multivariable linear regression analysis showed that postoperative acute kidney injury (AKI), immediate plasma troponin after operation, numbers of grafts, and CPB time were predicted the hospital LOS, while postoperative AKI, preoperative left ventricular ejection fraction, and immediate plasma troponin after operation were predicted the lengths of ICU stay.

CONCLUSION

Our analysis showed that increased preoperative plasma creatinine, postoperative renal dysfunction, and CPB time negatively affected the outcomes of patients who received intraoperative IABP insertion.

Complications of Temporary Percutaneous Mechanical Circulatory Support for Cardiogenic Shock: An Appraisal of Contemporary Literature

Cardiogenic shock (CS) is associated with hemodynamic compromise and end-organ hypoperfusion due to a primary cardiac etiology. In addition to vasoactive medications, percutaneous mechanical circulatory support (MCS) devices offer the ability to support the hemodynamics and prevent acute organ failure. Despite the wide array of available MCS devices for CS, there are limited data on the complications from these devices. In this review, we seek to summarize the complications of MCS devices in the contemporary era. Using a systems-based approach, this review covers domains of hematological, neurological, vascular, infectious, mechanical, and miscellaneous complications. These data are intended to provide a balanced narrative and aid in risk-benefit decision-making in this acutely ill population.

Training in Coronary Artery Bypass Surgery: Tips and Tricks of the Trade

Coronary artery bypass is often the first procedure cardiac surgeons are confronted with during their residencies. This article discusses the surgical steps and the potential difficulties encountered during this procedure and how they can be solved. The "point of view" of an experienced surgeon is provided to the trainees and to the readers.

IABP: history-evolution-pathophysiology-indications: what we need to know

Treatment with the intraaortic balloon pump (IABP) is the most common form of mechanical support for the failing heart. Augmentation of diastolic pressure during balloon inflation contributes to the coronary circulation and the presystolic deflation of the balloon reduces the resistance to systolic output. Consequently, the myocardial work is reduced. The overall effect of the IABP therapy is an increase in the myocardial oxygen supply/demand ratio and thus in endocardial viability.

This is an overall synopsis of what we need to know regarding IABP. Furthermore, this review article attempts to systematically delineate the pathophysiology linked with the hemodynamic consequences of IABP therapy. The authors also look at the future of the use of the balloon pump and conclude that the positive multi-systemic hemodynamic regulation during IABP treatment should further justify its use.
