Criteria for Transcatheter Aortic Valve Replacement (TAVR)
Any patient diagnosed with severe aortic stenosis that is deemed inoperable or high risk for open aortic valve replacement can be referred for TAVR evaluation. All potential candidates seen for evaluation will be educated and assessed by the multidisciplinary Robert Wood Johnson University Hospital team that includes cardiac surgeons, vascular surgeons, interventional cardiologists, cardiac anesthesiologists, echocardiologists, and a clinical nurse coordinator. Although some contraindications to TAVR are absolute, many are relative and are determined by individual program policy and experience. Patients should be presumed to be acceptable candidates until proven otherwise. If there is any question regarding an individual’s candidacy, the patient should be referred and the TAVR team will make the final determination.
Inclusion Criteria
- Patient has severe aortic valve stenosis per echo: mean gradient >40 mmHg or jet velocity greater than 4.0m/s and an aortic valve area of <0.8 cm2 or indexed EOA <0.5 cm2/m2
- NYHA >2
- Probability of death or serious, irreversible morbidity >50%
Exclusion criteria
- MI < 1 month before treatment
