Systematic analysis of myocardial immune progression in septic cardiomyopathy: Immune-related mechanisms in septic cardiomyopathy.

Background: The immune infiltration and molecular mechanisms underlying septic cardiomyopathy (SC) have not been completely elucidated. This study aimed to identify key genes related to SC and elucidate the potential molecular mechanisms.

Methods: The weighted correlation network analysis (WGCNA), linear models for microarray analysis (LIMMA), protein-protein interaction (PPI) network, CIBERSORT, Kyoto Encyclopedia of Genes and Genomes pathway (KEGG), and gene set enrichment analysis (GSEA) were applied to assess the key pathway and hub genes involved in SC.

Myocardial contrast echocardiographic diagnosis and follow-up of interventricular septal hematoma after retrograde intervention for a chronic total occlusion of a right coronary artery: a case report.

Background: Chronic total occlusion percutaneous coronary interventions (CTO-PCI) can be highly complex and are associated with an increased risk of complications. Coronary perforation (CP) is one of the most feared complications of CTO-PCI. Awareness of the potential consequence, as well as meticulous attention to patient monitoring, can aid in rapid treatment if it happens.

A deep learning approach with temporal consistency for automatic myocardial segmentation of quantitative myocardial contrast echocardiography.

Quantitative myocardial contrast echocardiography (MCE) has been proved to be valuable in detecting myocardial ischemia. During quantitative MCE analysis, myocardial segmentation is a critical step in determining accurate region of interests (ROIs). However, traditional myocardial segmentation mainly relies on manual tracing of myocardial contours, which is time-consuming and laborious.

Epicardial collateral channel for retrograded recanalization of chronic total occlusion percutaneous coronary intervention: Predictors of failure and procedural outcome.

Objectives: This study set out to identify significant lesion features of chronic total occlusion (CTO) that predict successful retrograde recanalization via epicardial collateral channels (CCs).

Background: Epicardial CCs remain essential in retrograde percutaneous coronary intervention (PCI) of CTO. However, the unpredictability of success and occurrence of complications limit the application of epicardial CCs for retrograde PCI technique for CTO.

Usefulness and Safety of a Novel Modification of the Retrograde Approach for the Long Tortuous Chronic Total Occlusion of Coronary Arteries.

The aim of this study was to evaluate the feasibility and efficacy of the Guidezilla guide extension catheter in a reverse controlled antegrade and retrograde subintimal tracking (CART) technique for chronic total occlusion (CTO) recanalization.We retrospectively collected 80 CTO cases using reverse CART technology from January 2015 to October 2015 and 20 CTO cases using Guidezilla reverse-CART technology from October 2015 to March 2016. Guidezilla was applied in cases when it was difficult to advance a retro-guidewire through an occlusion segment into the antegrade guide catheter.

Clinical Prediction Score for Successful Retrograde Procedure in Chronic Total Occlusion Percutaneous Coronary Intervention.

Objective: To develop and validate a prediction score for a successful retrograde procedure in chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Methods: A total of 228 CTO lesions in 223 patients who underwent PCI by retrograde approach were analyzed. All subjects were randomly grouped to a derivation set and a validation set at a ratio of 2:1.
