Long-term results of edge-to-edge and neochordal mitral repair for isolated anterior leaflet lesion: a propensity match analysis.

Objectives: Mitral regurgitation due to anterior mitral leaflet lesions is associated with an increased risk of mitral regurgitation recurrence after mitral valve repair compared with posterior leaflet-related lesions. Both edge-to-edge (E-to-E) and neochordal repair, associated with ring annuloplasty, have been used in our institution to address isolated anterior mitral leaflet lesions. The aim of this study was to compare the clinical and echocardiographic long-term results of those two approaches for isolated anterior mitral leaflet lesions by means of a propensity match analysis.

Distinct Responses of Cystic Fibrosis Epithelial Cells to SARS-CoV-2 and Influenza A Virus.

The COVID-19 pandemic has underscored the impact of viral infections on individuals with cystic fibrosis (CF). Initial observations suggested lower COVID-19 rates among CF populations; however, subsequent clinical data have presented a more complex scenario. This study aimed to investigate how bronchial epithelial cells from CF and non-CF individuals, including various CF transmembrane conductance regulator (CFTR) mutations, respond to infection with SARS-CoV-2 variants and SARS-CoV.

Long-term Results of Clover and Edge-to-Edge Leaflet Repair for Complex Tricuspid Regurgitation.

Background: The aim of this study was to report the long-term results of the clover and edge-to-edge repair techniques for complex tricuspid regurgitation (TR).

Methods: This was a single-center observational study. A competing risks proportional-hazards regression model, using the Fine and Gray model, was performed to analyze the time to TR ≥2+, considering death as a competing risk.

Modeling instream temperature from solar insolation under varying timber harvesting intensities using RPAS laser scanning.

Stream temperatures are influenced by the amount of solar insolation they receive. Increasing stream temperatures associated with climate warming pose detrimental health risks to freshwater ecosystems. In British Columbia (BC), Canada, timber harvesting along forested streams is managed using riparian buffer zones of varying widths and designations.

Neochordae implantation versus leaflet resection in mitral valve posterior leaflet prolapse and dilated left ventricle: a propensity score matching comparison with long-term follow-up.

Objectives: Uncorrected severe mitral regurgitation (MR) due to posterior prolapse leads to left ventricular dilatation. At this stage, mitral valve repair becomes mandatory to avoid permanent myocardial injury. However, which technique among neochoardae implantation and leaflet resection provides the best results in this scenario remains unknown.
