AI Article Synopsis
- * Researchers analyzed data from 148 patients who had normal heart rhythms before surgery, finding that 33.1% experienced PNAF post-surgery.
- * The results indicate that higher preoperative RDW levels are significantly linked to an increased risk of PNAF, suggesting that measuring RDW might help identify patients at risk during cardiac surgery.
Article Abstract
Purpose: The aim of this study was to evaluate the impact of preoperative red blood cell distribution width (RDW) values on the risk of post-operative new-onset atrial fibrillation (PNAF) during hospitalization following cardiac valve replacement surgery.
Materials And Methods: The clinical data of 148 patients with preoperative sinus rhythm who underwent cardiac valve replacement surgery at The First Affiliated Hospital of Anhui Medical University from September 2017 to June 2018 were retrospectively analysed. Univariate and multivariate logistic regression analyses were used to determine the relationship between preoperative RDW values and the development of PNAF.
Results: Forty-nine of the 148 patients (33.1%) developed PNAF. The median preoperative RDW was 13.1 (12.6-17.2), while the median RDW value was significantly higher in patients with PNAF than in those without PNAF [14.1 (13.2-15.0) 12.9 (12.4-13.5), < 0.001]. Multivariate logistic regression analysis showed that preoperative RDW values were significantly correlated with the occurrence of PNAF (odds ratio: 1.940, 95% confidence interval: 1.377-2.731, < 0.001).
Conclusions: Preoperative RDW is an independent risk factor for PNAF during hospitalization following cardiac valve replacement surgery. This finding suggests that preoperative RDW measurement may be used to stratify the risk for PNAF development in patients undergoing cardiac surgery.

Background: The lacking proper regulation of International Normalized Ratio (INR) as the main problem in patients with mechanical valve replacement surgery poses the risk of thrombosis and embolism on the one hand and the risk of bleeding on the other. For this reason, the correct monitoring of INR via the Time in Therapeutic Range (TTR) is needed. The present study aimed to explore the blood coagulation monitoring of patients with mechanical heart valve in Imam Ali Hospital of Kermanshah in 2021.

Background: The aim of this study is to identify factors associated with the development of long-term severe tricuspid regurgitation (TR) following mitral valve replacement (MVR).
Methods: A retrospective analysis was conducted involving 308 patients who underwent single-valve MVR at Xuzhou Central Hospital between April 2017 and December 2022. Preoperative color Doppler ultrasound indicated that all patients had either no or mild to moderate tricuspid regurgitation.

Background: Given the prevalence of cardiovascular disease, encountering difficult airways in this patient population is quite common. The challenge for anesthesiologists lies not only in establishing the airway but also in managing the hemodynamic instability caused by sympathetic activation during intubation. The purpose of this report is to describe the anesthetic experience of this patient with severe mitral and tricuspid regurgitation, atrial fibrillation with rapid ventricular response, and moderate pulmonary hypertension with an anticipated difficult airway.

Computed tomography (CT)-derived Epicardial Adipose Tissue (EAT) is linked to cardiovascular disease outcomes. However, its role in patients undergoing Transcatheter Aortic Valve Replacement (TAVR) and the interplay with aortic stenosis (AS) cardiac damage (CD) remains unexplored. We aim to investigate the relationship between EAT characteristics, AS CD, and all-cause mortality.

Background: Untreated severe heart valve disease (HVD) is associated with premature mortality. Research shows low population awareness of when to seek assessment and low focus on cardiac auscultation by physicians in primary care settings. We studied contemporary public knowledge of HVD and assessment by their general practitioner (GP) in Australia.
