Dear Cardiologist, why don’t you spare that extra minute in cath lab?
Suddenly . . . a primitive , common sense based question is asked! How many seconds are required to optimally dilate and deploy the coronary stent ?
This simple and elegant study from the prestigious CCI journal tries to answer.
Highlights
- 105 patients, 150 lesions , Three different stents were used
- Cypher Select (55%) , Xience V (30.%), Taxus Liberté (15.%)
- Three balloon inflation timing
- 5, 15, 25 seconds
- Complex lesion (B2) formed 26 %
This paper concludes, duration of stent balloon inflation has a significant impact on stent expansion. Stent deployment for >25 sec is recommended.
It again keeps the vital answer to our guess! Can we inflate it for 60 seconds ?
Final message
This seemingly simple paper conveys a strong message.
Time is every thing , . . . we have to be fast . . . where we need to (Time is muscle) and we have to be slow where we need to*

Further questions ?
- Can post dilatation be as efficacious as that of stent- balloon dilatation ?
- In difficult lesions , the sum of “Pre / Per / Post” balloon dilatation gives us net inflation time(NIT) Does it add any sense to our understanding of optimal stent deployment ?
