AF Regulatory Compliance & Standards 4

Question 1

The FDA-approved indication for left atrial appendage closure (LAAC) devices such as WATCHMAN is limited to patients who:

Accepted Answer

Have non-valvular AF with elevated stroke risk and long-term anticoagulation contraindications

Answer

FDA labeling for WATCHMAN specifies non-valvular AF patients at elevated stroke risk who have a reason to seek non-pharmacologic alternatives to long-term anticoagulation.

Question 2

Which of the following best describes the role of an Institutional Review Board (IRB) in the context of AF clinical trials?

Accepted Answer

IRBs review and approve research protocols to protect the rights and welfare of human subjects

Answer

IRBs review clinical trial protocols, including AF studies, to ensure research meets ethical standards and protects participant rights under 45 CFR Part 46.

Question 3

The AFFIRM trial findings influenced AF management guidelines primarily by demonstrating that:

Accepted Answer

Rate control was non-inferior to rhythm control in reducing mortality and had fewer adverse effects

Answer

AFFIRM showed rate control was non-inferior to rhythm control for mortality while associated with fewer hospitalizations and adverse drug effects.

Question 4

Under the National Correct Coding Initiative (NCCI) edits, which coding scenario would typically be bundled (not separately billable) when performing AF ablation?

Accepted Answer

Intracardiac echocardiography (ICE) performed as part of the ablation procedure by the same physician

Answer

NCCI edits bundle ICE guidance performed by the same physician during the ablation procedure, as it is considered integral to the primary procedure.

Question 5

According to ACC/AHA valve disease guidelines, which valvular condition defines 'valvular AF' requiring vitamin K antagonist therapy rather than DOACs?

Accepted Answer

Moderate-to-severe mitral stenosis or mechanical heart valves

Answer

Valvular AF specifically refers to AF with moderate-to-severe mitral stenosis or mechanical heart valves, where warfarin (VKA) is mandated over DOACs.
