Telemedicine-guided, very low-dose international normalized ratio self-control in patients with mechanical heart valve implants.

Aim: To study in patients performing international normalized ratio (INR) self-control the efficacy and safety of an INR target range of 1.6-2.1 for aortic valve replacement (AVR) and 2.

Paraprosthetic leak closure 28 years after mitral caged-ball Starr-Edwards implantation.

In this case report, we present a patient 28 years after mitral valve replacement with the Starr-Edwards prosthesis complicated by periprosthetic leak with severe aortic stenosis and moderate tricuspid regurgitation. We successfully repaired the periprosthetic regurgitation in a patient with extensive mitral annular calcification, without replacement of the valve. No apparent structural deterioration on the caged-ball valve was found.
