It was reported that significant resistance occurred while operating the devices and additional intervention was performed.The patient was diagnosed with deep venous disease (dvd) in the left anterior descending artery (lad) and right coronary artery (rca) and was referred for a double vessel plasty of the lad and rca.Vascular access was obtained via the femoral artery.The 80% stenosed, 2.50x16mm, de novo target lesion was located in the mildly tortuous ramus artery.A 12mm x 3.50 promus premier select was advanced and successfully deployed in the rca.It was then decided that a plasty of the lad would be performed.After crossing a run through wire, predilitation was performed with a non bsc balloon device.A 32 x 3.50mm promus premier select was advanced and deployed at high pressure in the lad due to diffused disease.Soon after deployment of the stent at high pressure in the lad, it was noticed that the ramus became pinched due to a plaque shift and there was no flow in the ramus.It was noted that significant resistance occurred while operating, and the event was likely due to deployment of a stent at high pressure in the lad.A 16 x 2.50 promus premier select stent was advanced immediately to bail out the stenting in the ramus.No further patient complications were reported and the patient was stable, responding well to medication.
