The purpose of this study is to examine if the measurements that we make by current standards for patients with both aortic stenosis (narrowed aortic valve) and atrial fibrillation underestimate severity of aortic stenosis and if that has any effect on timing of aortic valve surgery
The objective of this study is to determine the safety and efficacy of transcatheter aortic valve replacement (TAVR) via a transfemoral approach in HF patients with moderate AS as compared with OHFT.
The purpose of this study is to determine if aortic valve stenosis severity is underestimated in patients with a diagnosis of atrial fibrillation and aortic stenosis who are scheduled for cardioversion.
When the upper chambers of a person's heart receive irregular electrical signals it causes abnormal rhythm in the heart beat. This is called atrial fibrillation. Atrial fibrillation increases the chance of having a heart attack or stroke. Some patients also get new heart valves using a catheter. Often doctors give patients a medicine called a vitamin K antagonist (VKA), because it is considered the standard care. This study will see how edoxaban compares to VKA in patients who got a new heart valve by using a catheter. The study will compare the two drugs for up to three years after heart valve replacement, looking at the drug's overall side effects (called adverse events) and major bleeding.
Our overall goal is to determine whether the AVR improves SDB where present and sleep profiles (including sleepiness symptoms, quality of life and hypoxia).
