Which finding is a contraindication to valvuloplasty?

• A. Atrial thrombus
• B. Severe aortic stenosis
• C. Recent myocardial infarction
• D. Uncontrolled hypertension

Answer: (A)

A left atrial thrombus presents an absolute contraindication to valvuloplasty because manipulating or dilating the valve can dislodge the thrombus and send clots into the systemic circulation, risking a serious stroke or other embolic events. In mitral stenosis, this is especially critical, so the thrombus is treated and resolved with anticoagulation and follow-up imaging before attempting any balloon valvuloplasty. Other conditions may raise peri-procedural risk or influence timing, but they do not carry the same immediate risk of catastrophic embolization if the thrombus is present.
