CCS Cardiovascular Treatment Procedures 3

Question 1

Which ablation technique is used as first-line catheter-based therapy for typical atrial flutter?

Accepted Answer

Cavotricuspid isthmus ablation

Answer

Typical atrial flutter uses the cavotricuspid isthmus as an obligate part of the re-entrant circuit, making CTI ablation highly effective with >95% success rate.

Question 2

A patient with severe mitral stenosis has a pliable, non-calcified valve. The most appropriate percutaneous intervention is:

Accepted Answer

Percutaneous mitral balloon valvuloplasty (PMBV)

Answer

PMBV (also called balloon mitral commissurotomy) is the procedure of choice for suitable mitral stenosis, splitting the fused commissures to improve valve area.

Question 3

What is the primary hemodynamic goal when using a percutaneous left ventricular assist device (Impella) in high-risk PCI?

Accepted Answer

Unload the left ventricle and maintain cardiac output

Answer

The Impella device directly unloads the LV by pumping blood from the LV into the aorta, maintaining systemic perfusion during high-risk interventions.

Question 4

During permanent pacemaker implantation, the pacing lead is most commonly secured in which cardiac location for ventricular pacing?

Accepted Answer

Right ventricular apex or outflow tract

Answer

Transvenous RV pacing leads are typically positioned at the RV apex or septum/outflow tract via the subclavian or cephalic vein approach.

Question 5

A patient develops cardiac tamponade after an electrophysiology procedure. The immediate treatment is:

Accepted Answer

Pericardiocentesis under echocardiographic guidance

Answer

Pericardiocentesis is the emergent procedure to drain the pericardial effusion and relieve the life-threatening hemodynamic compromise of tamponade.
