Detailed explanation-1: -(T/F) The manufacturer’s prosthesis statistics and the patient’s previous echo reports should be used asa. comparison during serial echo exams. True.
Detailed explanation-2: -Echocardiography is the key noninvasive modality for evaluation of prosthetic valve structure and function [1]. Transthoracic echocardiography (TTE) is the mainstay for monitoring prosthetic valves and can generally identify normal function as well as evidence of valve dysfunction (stenosis).
Detailed explanation-3: -Biologic prosthetic valves are associated with a higher risk of reoperation than mechanical valves because of structural valve deterioration, but mechanical valves typically necessitate lifelong anticoagulation, which increases the risk of hemorrhage and thromboembolism.
Detailed explanation-4: -Issues of Concern Design of prosthetic heart valves focuses on four components: improved optimal hemodynamics, mechanical/biological durability, minimizing biological response to the prosthetic heart valve, and optimal delivery system.
Detailed explanation-5: -The type and size of the replacement valve. The date of surgery. Blood pressure and heart rate. The patient’s height, weight, and body surface area (BSA) to identify a possible patient prosthesis mismatch (PPM).
