Valvular heart disease and pregnancy: part II: prosthetic valves.

A large number of prosthetic heart valves (PHV) are being implanted in patients with both congenital and acquired valvular disease. Many of the recipients of such valves are women of childbearing age who desire to have children. The main issues involved with pregnancy in a patient with PHV include the selection of PHV in women during their childbearing age, risks to both the mother and the fetu...

Acupuncture in patients with valvular heart disease and prosthetic valves.

Endocarditis has been reported in patients with valvular heart disease who have undergone acupuncture treatment, although most have been associated with the use of semi-permanent needles. This has led reviewers to suggest that acupuncture may not only be contraindicated in such patients but that prophylactic antibiotics should be given. This study investigated the use of acupuncture treatment i...

Prosthetic Aortic Heart Valves

In this review, the anatomy and structure of the aortic valve and its prostheses are comprehensively discussed. Cardiac anatomy and function, human heart valves and their prostheses are also extensively discussed. The current status of prosthetic heart valves along with the next generation of these devices is broadly deliberated. Ather promising options such astranscatheter technologies (percut...

Prosthetic heart valves.

The first prosthetic valve was implanted by Hufnagel in 1952 in a patient with aortic insufficiency. Since then, prosthetic valves have evolved into various mechanical and bioprosthetic shapes and sizes. Despite the excitement surrounding the current development of prosthetic heart valves, surgically implanted valves remain the mainstay of current practice, and this article discusses the hemody...
