Long-term evaluation of venous tissue in the construction of cardiac valves
Abstract:
We present the evolution of venous tissue, used as a mitral or tricuspid prosthesis or in the reconstruction of the right ventricular outlet tract, for periods of up to 18 months. A histological and hydrodynamic study is made of the valves after sacrificing the animals. The venous tissue showed fibrosis, structural disorganization, elastosis, elastorexis and, above all, intense calcification in heavy deposits. Since the venous tissue evolved toward fibrosis and calcification, its use is considered contraindicated.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
