Structural Heart Interventions
TAVI (Transcatheter Aortic Valve Implantation)
The minimally invasive placement under X-ray guidance of a bioprosthetic aortic valve, typically via a puncture of the femoral artery (groin) to the position of the old poorly functioning aortic valve, where the new valve is expanded, pushing the old valve out of the way and taking over valve function.
PFO (Patent Foramen Ovale) Closure
Increasingly indicated in patients with their first Stroke prior to age 60 years. The Foramen Ovale is a congenital communication allowing blood flow from the right to left atrium present in all prior to birth, but remaining patent in 25% of the general population, but nearly 50% of those with stroke prior to age 60 years. PFO Closure is typically performed via placement of an Amplatzer PFO device under Xray guidance via puncture of the femoral vein (groin).
ASD (Atrial Septal Defect) Closure
A Congenital defect (hole) in the atrial septum which allows blood flow from the left to right atrium increasing strain on the right side of the heart leading to complications in adult life if untreated. ASD Closure is performed under Xray and Ultrasound guidance via puncture of the femoral vein (groin).
LAA (Left Atrial Appendage) Closure
The LAA is a small outpouching of the Left Atrium responsible for the majority of strokes in Atrial Fibrillation. LAA Closure with with either a Watchman or Amulet device is indicated in patients unable to take anticoagulation therapy to reduce stroke risk
