During a mitral valve clip procedure, which of the following would be true when orienting the device?

++
++
++

A. When crossing the septum, the device catheter should be pointed posteriorly to best cross the mitral valve.

++
++

B. To clip medial or lateral parts of the valve, the clip may need to be rotated to be perpendicular to the coaptation plane.

++
++

C. The location of the transseptal puncture is less important than the direction of the catheter.

++
++

D. A patent foramen ovale can be used to cross the septum and deliver the device, avoiding the need for a transseptal puncture.

+
++

The correct answer is B.

++
++
++

Which of the following is least likely to increase the risk of pacemaker implants during a transcatheter aortic valve replacement?

++
++
++

A. A low implant position in the left ventricular outflow tract (LVOT).

++
++

B. Dense LVOT calcification.

++
++

C. A preexisting right bundle branch block.

++
++

D. Transapical approach to the implant.

++
++

E. Use of a self-expanding prosthesis instead of a balloon-expanding prosthesis.

+
++

The correct answer is D.

++
++
++

When closing an atrial septal defect, which rim, when missing, is most likely to increase the risk of device embolization and why?

++
++
++

A. Retroaortic rim due to motion of the aorta.

++
++

B. Retroaortic rim due to tension on the device by the delivery cable.

++
++

C. Posterior rim due to limited atrial space.

++
++

D. Inferior vena cava rim due to tension on the device by the delivery cable.

++
++

E. Inferior vena cava rim due to proximity to the tricuspid valve.

+
++

The correct answer is D.

++
++
++

In which of the following interventions is there no risk of coronary artery injury or occlusion?

++
++
++

A. Transcatheter aortic valve replacement (TAVR).

++
++

B. Coronary sinus annuloplasty.

++
++

C. Device closure of an atrial septal defect.

++
++

D. Transcatheter valve implantation in the pulmonic position.

+
++

The correct answer is C.
