An intra-aortic balloon pump (IABP) is a device of internal counterpulsation. Inflation of the balloon in diastole results in a potential increase in coronary blood flow and an improvement in systemic perfusion, and deflation at the end of diastole reduces left ventricular afterload, although the hemodynamic effects are relatively small. ⋯ Meanwhile, novel improvements in knowledge and technology are pushing the boundaries of this device. In this review, we summarize the basic physiology and current evidence of this device and then discuss the outlook and implications of IABP in the future.

We experienced a 33-year-old patient with D-looped transposition of the great arteries (D-TGA) and a history of Senning operation who was referred to our institute with cardiogenic shock and subsequently underwent urgent paracorporeal ventricular assist device (VAD) implantation, which was a first in Japan, that was eventually converted to a durable VAD. Central venous pressure was maintained relatively high to obtain VAD filling and recover end-organ dysfunction, given the migration of the inflow cannula due to rich trabeculae carneae of the anatomical right ventricle (systemic ventricle in this case).

The purpose of this article is to systematically evaluate the prevalence, outcomes, and risk factors of new-onset atrial fibrillation (AF) in critically ill patients. Medline, Embase, Science Citation Index, Wanfang, CNKI, and Wiley Online Library were thoroughly searched to identify relevant studies. Studies were assessed for methodological quality using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. ⋯ New-onset AF incidence rate is high in critically ill patients. New-onset AF is associated with worse outcomes. Further studies should be done to explore how to prevent and treat new-onset AF in critically ill patients.
