Editorial Valve in Valve Another Milestone for Transcatheter Valve Therapy

چکیده
The first mechanical heart valve prosthesis, designed by Dr Charles Hufnagel, was implanted to the descending aorta of a 30-year-old woman with severe aortic regurgitation in 1952.1 Eight years after the initial successful prosthetic valve implantation, Dr Harken sutured a prosthetic valve (Starr Edwards Valve) to the aortic annulus after removing the diseased native valve. During the ensuing years, different types of valves made from pyrolytic carbon were tried. Though they successfully remedied the aortic valve disease, mechanical prosthesis required lifelong anticoagulation, resulting in high rates of bleeding and thrombosis complications.

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...

Certain subsets of high-risk mitral valve patients are not suitable candidates for transcatheter therapies. The objective of this report is to present a young patient with combined mitral valve and coronary artery disease to illustrate these challenges.In this report, we present a 47-year-old man with longstanding HIV infection who was referred with severe mitral regurgitation (MR) and profound...

متن کاملTranscranial Doppler application for risk assessment of stroke in patients with mechanical mitral valve
Introduction: Observing microembolic signals in brain vessels by transcranial Doppler technology is a very common finding in patients with mechanical heart valve. These signals are almost always clinically asymptomatic. The aim of this study was assessment of transcranial Doppler in detecting probability of stroke in patients with mechanical heart valve. Methods: This descriptive study was ca...
