Background: Percutaneous left atrial appendage occlusion (LAAO) is an alternative for stroke prevention in patients with atrial fibrillation with contraindications to oral anticoagulation. Population-level real-world data describing the use and outcomes of LAAO procedures are evolving, with a paucity of longer-term follow-up data. We report on the patient characteristics, procedure complications, and longer-term clinical outcomes in all patients undergoing LAAO procedures in Ontario, Canada.

We sought to understand if there was variation in the use of OMT between hospitals for patients with nonobstructive coronary artery disease, the factors associated with such variation, and its clinical consequences.
Methods And Results: Using a population-level clinical registry in Ontario, Canada, we identified all patients >66 years undergoing coronary angiography for the indication of stable angina, who had nonobstructive coronary artery disease between November 1, 2010, and October 31, 2013.
Article Synopsis
- Elderly patients who undergo transcatheter aortic valve replacement (TAVR) may face hospital readmissions, and this study aims to understand the relationship between hospital stay length and readmission risk.
- Researchers analyzed data from 709 patients who had elective TAVR procedures, measuring their hospital stay length and tracking readmissions at 30 days and 1 year.
- The findings revealed that a shorter hospital stay after TAVR was not linked to increased readmission within 30 days or 1 year, but longer stays were associated with a higher risk of readmission after one year.
Background: Little is known about variations in the quality of ambulatory care between urban and rural communities for patients with stable ischemic heart disease. The objectives of this study were to understand the effect of rurality on variations of ambulatory processes of care and outcomes for patients with stable ischemic heart disease.
Methods And Results: A population-based cohort study was conducted, which included all Ontario patients with stable ischemic heart disease confirmed on cardiac catheterization between October 1, 2008, and September 30, 2011.
