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.

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).

Case Reports
Atypical Slow-Slow Atrioventricular Nodal Reentrant Tachycardia with Use of a Superior Slow Pathway.
We report a case of atypical slow-slow atrioventricular nodal reentrant tachycardia (AVNRT) utilizing a superior slow pathway as a retrograde limb. The standard electrophysiological criteria confirm the diagnosis of this AVNRT by successfully excluding a diagnosis of atrial tachycardia and atrioventricular reentrant tachycardia. The earliest atrial activation during tachycardia was found at the interatrial septum 17.5 mm superior to the site identified during retrograde conduction with the fast pathway. The tachycardia was not inducible after ablation at the right posterior septum, consistent with successful ablation of the typical slow pathway.

Transcatheter aortic valve implantation (TAVI) using a transfemoral approach under local anesthesia with conscious sedation (LACS) is becoming an increasingly common TAVI strategy. However, patients who are awake during the TAVI procedure can experience stress, anxiety, and pain, even when LACS is used. Clinical hypnotherapy is an anxiolytic intervention that can be beneficial for patients undergoing invasive surgery. ⋯ The multiple regression analysis showed that being male, hypnotherapy, and the composite complication score were independently associated with the length of stay in the ICU. The adjunctive hypnotherapy on LACS among transfemoral TAVI patients may facilitate perioperative management. However, a prospective randomized study is necessary to confirm the efficacy of hypnotherapy among TAVI patients.
