Summary: Objective of this study was to determine the impact of pulmonary artery catheter insertion on short-term postoperative outcomes in patients undergoing open cardiac surgery. The study found that pulmonary artery catheter use did not improve operative mortality in the overall cohort or in specific subgroups. Although there were longer intensive care unit stays and more red blood cell transfusions in the pulmonary artery catheterization group, the postoperative outcomes were otherwise similar.

Summary: In Fontan patients with junctional rhythm, atrial pacing decreased left atrial pressure, increased cardiac output, and did not significantly change pulmonary artery pressure.

Summary: This study investigates the characteristics and predictors of acute and delayed sinus node dysfunction (SND) after ablation of atrial flutter (AFL). The majority of patients with acute SND still require pacemaker implantation despite initial improvement. Close monitoring of patients for at least one year after AFL ablation is reasonable.

Summary: Atrial flutter is the second most common atrial tachyarrhythmia, and catheter ablation is a commonly used treatment. However, it may lead to sick sinus syndrome after terminating long-term persistent atrial flutter. The prediction of this syndrome before surgery has not been explored.

Summary: In patients undergoing catheter ablation for atrial fibrillation with coexisting heart failure, all cardiac disorders showed significant improvement after the procedure and most of these improvements were maintained during the 5-year follow-up period.

Summary: The sinoatrial node (SAN) is important for maintaining proper cardiac rhythm and contraction, but abnormalities within it can cause sinus node dysfunction (SND), leading to increased risk of cardiac arrhythmias. Current treatment for SND is limited to pacemaker implantation, but emerging evidence on genetic abnormalities associated with SND may lead to the development of more effective therapies. This review article examines the anatomy and pathophysiology of the SAN, the epidemiology of SND, and discusses the most common genetic mutations correlated with SND, as well as future research and therapeutic opportunities in this field.

Summary: This study analyzed the relationship between the timing of catheter ablation for atrial fibrillation (AF) and the need for permanent pacemaker (PPM) implantation in patients with sick sinus syndrome. The results showed that patients who underwent catheter ablation within 5 years of sick sinus syndrome diagnosis had the lowest rate of PPM implantation.

Summary: This study found that a higher pulmonary artery pressure (PAP) is associated with an increased risk of recurrence after radiofrequency catheter ablation in patients with paroxysmal atrial fibrillation, suggesting a mechanism by which pulmonary vascular dysfunction may lead to pulmonary vein impairment and left atrial remodeling.

Summary: This study aimed to explore the current use of PACs in cardiac intensive care units and investigate the factors influencing their use. The study found that mechanical circulatory support and heart failure were the most influential patient-level factors for PAC use. There was significant variation in the proportion of PAC use among different study centers, and the use of PACs was associated with higher survival in cardiac patients with shock.

Summary: Sinus node dysfunction is a common arrhythmia disorder associated with aging, fibrosis, inflammation, oxidative stress, and autonomic dysfunction. Currently, there are no effective drugs for treating chronic sinus node dysfunction. Natural active substances and Chinese herbal medicines, such as astragaloside IV, quercetin, and ginsenosides, have shown antioxidant effects, reduce fibrosis, and maintain ion channel stability, providing promising drugs for treating sinus node dysfunction.

Summary: This study compared the procedural characteristics and outcomes of cryoablation and radiofrequency ablation for AVN ablation in patients with HBP. Cryoablation did not show any advantage over RFA and tended to require more redo procedures. Maintaining a distance of >= 6 mm from the His lead tip is recommended to avoid a rise in capture thresholds.

Summary: This study systematically reviewed the evidence on the prevalence of sinus node dysfunction (SND), permanent pacemaker (PPM) implantation, and their management approaches following cardiac surgeries. The results showed that patients undergoing maze and maze-valve procedures are at higher risk of post-op SND, while lone valve surgery had the lowest prevalence of PPM implantation. Rating: 8/10

Summary: Sinus node artery occlusion (SNO) is a rare complication of percutaneous coronary intervention (PCI) that often occurs during interventions for acute coronary syndrome (ACS), leading to sinus node dysfunction. The majority of patients with SNO responded to medical treatment for sinus node dysfunction, with only a few cases requiring permanent pacemaker implantation.

Summary: Sinus node dysfunction (SND) with junctional rhythm (JR) is common after the Fontan operation. Atrial pacing (AP) can restore atrioventricular (AV) synchrony, but carries significant morbidity. This study found that compared to AP, JR was associated with a significant reduction in cardiac output and diastolic function, and an increased prevalence of pulmonary vein flow reversal. There were no differences between paced and slow-paced conditions.
