Acute Stent Loss and Its Retrieval of a Long, Tapering Morph Stent in a Tortuous, Calcified Lesion.

A 72-year-old male with diabetes and smoking as coronary risk factors was evaluated for chronic stable angina - Canadian Cardiovascular Society III - despite guideline directed medical treatment which revealed a diffuse, tortuous, calcified narrowing (90% stenosis) in left circumflex (LCx) coronary artery. After predilatation, a 3.0 - 2.5 × 60 mm BioMime Morph stent - long tapering stent (Sirolimus eluting stent, Meril life Sciences, India) - was tracked which failed and dislodged to right deep femoral artery during its pullback. It was successfully retrieved by EN snare: 6 - 10 mm (Merit Medical, USA) by contralateral femoral approach. Lesion was further dilated and successfully stented with another 3.0 - 2.5 × 60 mm BioMime Morph stent at 10 atm pressure showing proper stents expansion with TIMI-3 coronary flow. Our case highlights trackibility issues and importance of adequate lesion preparation before stent deployment in a tortuous and calcified vessel especially with very long stent. To the best of our knowledge, this is the first such case report demonstrating dislodgement and successful retrieval of long, tapered Morph stent.
