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 کاملWE-C-217BCD-02: Design of an MR Compatible Rotating Anode X-Ray Tube.
PURPOSE To design a rotating anode X-ray tube capable of operating in strong magnetic field environments. This tube design can be used in 'close proximity" hybrid X-ray/MR system geometries where the imaging fields of view are separated by only ∼1.2 meters. METHODS Existing rotating anode X-ray tube designs fail in strong magnetic field environments because the fields alter the electron traje...
متن کاملAortic valve replacement after esophagectomy with substernal gastric tube reconstruction.
A 67-year-old woman with a history of esophagectomy with substernal gastric tube (GT) reconstruction and left lower lobectomy required aortic valve replacement (AVR) for aortic valve regurgitation and stenosis. Through a median sternotomy (MS) with cardiopulmonary bypass (CPB), we performed AVR without injury to the GT. Careful peeling of the GT and detailed information of the operative field b...
متن کاملUse of aortic valve homografts for aortic valve replacement.
One hundred sixty-nine patients underwent replacement of the aortic valve with an aortic valve homograft; of these patients 17 had concomitant commissurotomy or annuloplasty for an associated mitral valve lesion. Homografts were prepared by sterilization with beta-propiolactone solution and stored in Hanks' solution, or were prepared by sterilization with irradiation and stored at -70 C. Operat...
