Q

Can a 6250-MP or 6250-MPX be deep seated in the CS?

A

only the 6250-MPX can be deep seated into the CS or used to sub-select a CS branch due to its tapered end

17
Q

Which Attain Command catheter should be used to gain CS access in patients with atrial enlargement or has a CS with a vertical take-off?

A

6250-EH or 6250-EHXL
- extended hook

18
Q

In which patients is the Extended Hook (6250-EH or 6250-EHXL) Attain Command catheter a good choice for CS cannulation/access?

A

patients with atrial enlargement or who have a CS with a vertical take-off?

19
Q

Which Attain Command catheter should be used to gain CS access in patients where the CS is obstructed by the Thebesian Valve?

A

6250-AM
- amplatz catheter
- lead with a guidewire so the tip does not prolapse

20
Q

Which Attain Command catheter should be used to gain CS access in patients where a right sided approach is being used?

A

6250-MPR
- Multi-purpose Right

21
Q

In which patients is the 6250-AM (amplatz) Attain Command catheter a good choice for CS cannulation/access?

A

patients where the CS is obstructed by the Thebesian Valve

22
Q

In which patients is the 3D curve Attain Command Surevalve catheter a good choice for CS cannulation/access?

A

use when the CS is more posterior than normal

23
Q

The Attain Perform 4598 is recommended for what size vessels?

A

Medium to Large diameter vessels

24
Q

The Attain Perform 4298 is recommended for what size vessels?

A

Medium vessel diameter

25
Q

The Attain Perform 4398 is recommended for what size vessels?

A

Small diameter vessels or with acute curvatures

26
Q

What is the model number for there Attain Stability Quad LV lead?

A

4798

27
Q

What type of lead is the 4798?

A

Active fix LV lead
-> has helix in between poles 2-3 with a mechanical stop to prevent over fixating and possible vessel trauma

28
Q

How is the Attain Stability Quad (4798) fixated to the vessel wall?

A

A helix in between poles 2-3
-> 0.2mm in diameter
-> is electrically inactive
-> has mechanical stop to prevent over rotation

29
Q

What are the distances for the following on an Attain Performa family of the quadripolar leads:

1) LV1 to LV2
2) LV2 to LV3
3) LV3 to LV4

A

1) 21mm
2) 1.2mm
3) 21mm

30
Q

What is important to remember when inserting/advancing the Attain Stability Quad (4798) lead through the Surevalve of the attain command catheter?

A

Rotate the lead counterclockwise as it is advanced thru the Surevalve

31
Q

When should lead testing be done when implanting a 3830 Attain Stability Quad lead?

A

After the lead is fixated because the position of the electrodes will change/move as the lead is screwed in place

32
Q

What is done to ensure the helix of the 3830 Attain Stability Quad lead is properly fixed?

A
  • retract the guide wire to appx LV4 and perform the Push and Pull test under live fluoroscopy
33
Q

Should the 3830 Attain Stability Quad lead be wedge into place?

A

No, wedging the lead may prevent helix rotation and fixation

34
Q

What items are included with the 3830 Attain Stability Quad packaging?

A
  • 4 straight stylets (2 grey, 2 purple)
  • 2 j-shaped stylets
  • guidewire insertion tool
  • 1 torque tool
  • 1 guidewire clip
35
Q

What is the purpose of the j-shaped stylets that come with the 3830 Attain Stability Quad lead?

A

Stylets are used to pressed the helix against the vessel wall when screwing into place
