Which ablation technique is used as first-line catheter-based therapy for typical atrial flutter?
Answer: Cavotricuspid isthmus ablation
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.
A patient with severe mitral stenosis has a pliable, non-calcified valve. The most appropriate percutaneous intervention is:
Answer: Percutaneous mitral balloon valvuloplasty (PMBV)
PMBV (also called balloon mitral commissurotomy) is the procedure of choice for suitable mitral stenosis, splitting the fused commissures to improve valve area.
What is the primary hemodynamic goal when using a percutaneous left ventricular assist device (Impella) in high-risk PCI?
Answer: Unload the left ventricle and maintain cardiac output
The Impella device directly unloads the LV by pumping blood from the LV into the aorta, maintaining systemic perfusion during high-risk interventions.
During permanent pacemaker implantation, the pacing lead is most commonly secured in which cardiac location for ventricular pacing?
Answer: Right ventricular apex or outflow tract
Transvenous RV pacing leads are typically positioned at the RV apex or septum/outflow tract via the subclavian or cephalic vein approach.
A patient develops cardiac tamponade after an electrophysiology procedure. The immediate treatment is:
Answer: Pericardiocentesis under echocardiographic guidance
Pericardiocentesis is the emergent procedure to drain the pericardial effusion and relieve the life-threatening hemodynamic compromise of tamponade.
Which energy source is used in cryoablation for pulmonary vein isolation?
Answer: Extreme cold (nitrous oxide or liquid nitrogen)
Cryoablation uses extreme cold delivered via the Arctic Front cryoballoon to create circumferential lesions around pulmonary vein ostia.
A patient with end-stage heart failure refractory to all therapies and not a transplant candidate is considered for which device?
Answer: Destination therapy LVAD
Destination therapy LVAD (e.g., HeartMate 3) is FDA-approved as a permanent alternative to transplantation for patients with end-stage HF who do not qualify for transplant.
