Resolute integrity drug eluting stents were among a number of drug eluting stents used in a study involving autopsy cases which analysed vascular responses to coronary calcification following implantation of newer-generation drug-eluting stents in humans.
Out of 134 stents analysed, 29 were resolute integrity stents.
Lesions treated included the left main, left circumflex, left anterior artery descending and right coronary artery.
Adverse events experienced included stent thrombosis, restenosis, dissection, stent related death, non- stent related cardiac death and non-cardiac death, explant due to heart transplant death and target lesion revascularization.
Malfunctions reported included stent fracture and strut malapposition which were assessed through imaging.
It was also reported that a (b)(6) year old patient with a medical history of hypertension, diabetes and coronary artery disease had a resolute integrity des implanted.
One year post implant the patient died.
Low power images of stented sections for this patient demonstrated in-stent restenosis with a large medial tear in a severely calcified artery.
Strut malapposition was also observed.
