coMparison Between invAsive and Non-invasive assessmenT on Blood Pressure and Cardiac Function in HealthY Participants

This is a cross-sectional cohort study which aims to compare the invasive and non-invasive assessments on aortic blood pressure and cardiac funtion in subjects without history of cardio-vascular disease. Left ventricular (LV) filling pressure, LV volume, and aortic blood pressure will be measured invasively. Non-invasive assessment includes echocardiography,aortic, and carotid blood pressure measurement.

Renal Artery Sympathetic Denervation by Catheter Ablation After Pulmonary Vein Isolation (PVI) for Persistent Atrial Fibrillation

Atrial fibrillation (AF) is the most common arrhythmia and it is associated with significant morbidity and mortality. Electrical isolation of the pulmonary vein (PVI) by radiofrequency energy or cryoablation has been shown to be an effective treatment of AF by reducing morbidity, improving quality of life and functional capacity. Renal artery sympathetic denervation (RND) by catheter ablation has been shown in a preliminary study to improve outcome of PVI in patients with paro...


People: The absolute prevalence of undiagnosed atrial fibrillation in individuals over 60 years of age is 2.2%, equivalent to 20.1% of the overall prevalence of AF and there is not sufficient evidence regarding the procedures that may be most effective for achieving an early diagnosis of AF and reducing the associated stroke risks. Intervention: Characterize the ideal population for searching unknown atrial fibrillation and develop an understanding of actions that could be tak...

The Genetic Basis for Atrial Fibrillation

Atrial fibrillation (AF) is reaching epidemic proportions in the aging U.S. and European populations, but the mechanisms of increased susceptibility to atrial fibrillation are still unknown. In this study, we look to further examine genetic and medical co-morbidity influence of atrial fibrillation duration and response to medications. In Specific Aim 1, we propose the creation of a Veterans Affairs AF Biorepository (VAAFBio), which is a resource that will collect and store clin...

Home Blood Pressure in Hypertension Management

This is a prospective randomized study with two arms: the Conventional and Ambulatory blood pressure monitoring arm and the Home blood pressure monitoring arm. The study will include both previously treated and untreated individuals.

Femoral Vein Hemostasis After Ablation for Atrial Fibrillation With Manual Pressure Versus a Figure of 8 Suture

Patients who undergo ablation for AF typically have 2 sheaths placed in each groin, including a large sheath when the Cryo Balloon is used for pulmonary vein isolation. During the procedure, heparin is administered to maintain a target ACT > 300 seconds. At the conclusion of the procedure, the venous sheaths are removed and hemostasis is obtained. There are at least 2 ways of obtaining hemostasis after venous access. In the manual hemostasis approach, an ACT is checked and prot...

Biological Bank for Atrial Fibrillation and Stroke

Atrial fibrillation (AF) is the most common cardiac arrhythmia encountered in clinical practice. This arrhythmia is responsible for 15% of strokes and more than 30% of strokes on people over 65 years. According to studies, 30 to 40% of isolated atrial fibrillations could be familial.
