Case Title

An approach to markedly tortuous lesion

Case History

66 year old man with no apparent risk factors except tobacco chewing, came in with chronic stable angina, NY class 2-3 coronary angio showed following findings.

Investigation Reports

Click on the thumbnail images to see the videos
Long left main - no significant disease LAD proximal segment free from disease, distal segment to be evaluated from the other views. Good filling of PDA from collaterals donated by LAD circumflex artery shows markedly tortuous MID segment stenosis of almost 80-90% severity. At one stage it was thought that this could be a bridging collateral rather than a true channel.
LAD is profiled correctly. 50-60% long stenosis at the junction of proximal and MID segment
In this view the circumflex artery shows extremely tight with marked tortousity mid segment stenosis of about 15 mm in size.

Angioplasty Procedure

Strategy: Notice that there is a long left main with almost right angled origin of circumflex this kind of an anatomy needs excellent back up. An average wire may continue to prolapse into the LAD particularly if there is an angulation in the proximal circumflex. Here choice of guide catheter should be either extra backup EBU, or VODA curve (Boston scientific). In my experience hydrophilic wire is ideal for a lesion like this. Notice that angulation of each curve of tortousity with in the lesion is very small and therefore wire was shaped at a distance of only 1.0-2.0 mm from the tip. A sharp bend was created with the tip of the needle. It is possible that one may have to change several wires and therefore over the wire balloon is an appropriate choice

Notice EBU catheter gaining support from opposite aortic valve. Choice pt extra support wire is negotiated up to the distal end of the lesion, with the help of 1.5mm of over the wire balloon. The wire would not go beyond this point. This is not uncommon at all. In this case the reason is that the wire still has to negotiate 2 tiny acute bends unfortunately once the wire crosses the tight portion of the lesion it looses torquebility.

Please Note: In presence of the balloon support use of force injudiciously on the wire could result into dissection.

We change the wire and select a stronger wire like shinobi. This wire easily crosses the lesion. Subsequently after crossing the lesion with the balloon we change the wire to a little softer wire like BMW
Dilatation of the lesion with 2 mm maverick balloon.
Deployment of the 2.5x24 mm Taxus stent at 14 atm.
Notice excellent post stenting results
