Transcatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کامل“Silent” Acute Native Valve Leaflet Avulsion during Transcatheter Aortic Valve Replacement
An 86 year old female was referred to our facility for management of severe symptomatic aortic stenosis manifested as dyspnea at rest and syncope. Our multidisciplinary heart valve team deemed her to be high risk for surgical AVR due to NYHA functional class IV congestive heart failure, severe right ventricular dysfunction, pulmonary hypertension, chronic lung disease and diabetes mellitus. Tra...
متن کاملTranscatheter Aortic Valve Replacement
With the worldwide number of TAVR procedures rapidly approaching 200,000, coupled with an amassed knowledge spanning over a decade, we are able to now reflect on the evolution of TAVR and how changes in technology, operator/institution experience, and patient selection have ultimately affected clinical outcomes. With this in mind, in this issue of JACC: Cardiovascular Interventions, Beohar et a...
متن کاملTranscatheter Aortic Valve Implantation
A 97-year-old man was referred for assessment to our transcather aortic valve implantation (TAVI) team. He had suffered multiple hospitalizations for heart failure with a signifi cantly elevated BNP at 1830 pg/mL. At the time of assessment, he had grade IV New York Heart Association (NYHA) symptoms. Until recently, he had been working actively, but this had subsequently been severely limited by...
متن کاملTranscatheter Aortic Valve Implantation
Calcific aortic stenosis (AS) is the most common form of degenerative heart valve disease in developed countries. AS predominantly affects the elderly with a prevalence of 4% in people over the age of 80 years. With increasing longevity and an ageing population the absolute number of people afflicted with AS is set to rise. The clinical course of the disease is insidious at first (Ross & Braunw...
