A client is scheduled for percutaneous balloon valvuloplasty to treat mitral stenosis. When explaining the advantage of valvuloplasty instead of valve replacement to the client, which information will the nurse include?
Ongoing cardiac care by a health care provider is unnecessary after valvuloplasty
Lifelong anticoagulant therapy is needed after mechanical valve replacement
Biologic replacement valves require the use of immunosuppressive drugs
Mechanical mitral valves require replacement approximately every 5-years
The Correct Answer is B
A. Ongoing cardiac care is still necessary after valvuloplasty to monitor valve function and complications.
B. Mechanical valve replacements require lifelong anticoagulant therapy to prevent thromboembolism, which is an important consideration when comparing with valvuloplasty.
C. Biologic valves do not require immunosuppressive drugs because they are derived from animal tissue.
D. Mechanical valves are durable and often last longer than 5 years, usually 10-20 years or more before replacement might be needed.

Correct Answer is A
Explanation
A. An echocardiogram is the most helpful noninvasive tool for diagnosing cardiomyopathy. It provides detailed information about chamber size, wall motion, ventricular function, and left ventricular hypertrophy, all of which are essential in evaluating cardiomyopathy.
B. Arterial blood gases (ABGs) assess oxygenation and acid-base balance but do not provide structural or functional cardiac details.
C. Swan-Ganz analysis (pulmonary artery catheter) can measure pressures in the heart but is invasive and typically used for hemodynamic monitoring, not initial diagnosis.
D. Cardiac catheterization can show coronary anatomy and pressures, but it is not the first-line test for evaluating cardiomyopathy unless ischemic disease is suspected.
