Comprehensive Echocardiographic Assessment of Mechanical Tricuspid Valve Prostheses Based on Early Post-Implantation Echocardiographic Studies

These calculated threshold values (mean + 2 SD) are useful for identifying normal tricuspid mechanical valve function. Prostheses with values for hemodynamic variables that are outside the mean + 2 SD parameters that we have calculated are most likely to be dysfunctional. However, in rare cases, mechanical tricuspid valve prostheses may be dysfunctional even when their hemodynamic parameters are within these specified ranges because of small body surface area or other factors.
