Compared with bare-metal stents (BMS),drug-eluting stems (DES)have shown better clinical outcomes for pa- tients undergoing percutaneous coronary intervention (PCI) by inhibition of neo-intirnal hyperplasia.[1]However,early- generation DES produced late thrombotic events,more than l-year,by delaying arterial healing of stented vessels,[2-5] New-generation DES have been developed'with thinner stent struts,more biocompatible polymer coatings for drug release,and a variety of antiproliferative agents with similar or superior anti-restenotic efficacy.[6]This development has led to a significant improvement in the efficacy and safety of new-generation DES,and consistently lower rates of very late stent thrombosis (VLST).[7,8]In fact,use of new-ge- neration DES is the standard treatment in contemporary PCI practice.[9]

0ctogenarians represent the fastest growing group of patients undergoing percutaneous coronary intervention(PCI),now constituting more than one in five patients treated with PCI in real-world practice.[1,2]Comparing coronary lesion characteristics of patients aged<≥80 years to those≥80 years undergoing PCI,the octogenarians have a higher prevalence of calcified and ostial lesions,tortuous coronary anatomy,multi-vessel disease and left main stem(LMS)stenosis.⑶Furthermore,they often have greater ischemic burden than their younger counterparts,suggesting an even greater benefit following revascularization.

Heavily calcified coronary lesions continue to represent a challenge for percutaneous coronary intervention(PCI),as they are difficult to dilate,and it is difficult to deliver and implant drug-eluting stents(DES)*** stent deployment is associated with high rates of periprocedural complications and suboptimal long-term clinical outcomes.[1]Thanks to the introduction of several adjunctive PCI tools,like cutting and scoring balloons,and to the novel intravascular lithotripsy technology,the treatment of such lesions has become increasingly feasible,predictable and safe.

OBJECTIVES To verify whether incomplete revascularisation(IR),quantified using the rSYNTAX(Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery)score andΔSYNTAX%score,could predict short-(in-hospital mortality)and long-term outcomes(12-month mortality)in octogenarians undergoing percutaneous coronary intervention(PCI).METHODS&RESULTS A retrospective analysis of 665 consecutive octogenarian patients presenting for PCI to a UK centre was *** baseline SYNTAX and rSYNTAX scores were assessed from angiographic images.ΔSYNTAX%score was calculated(ΔSYNTAX%=((SYNTAX-rSYNTAX)/SYNTAX)×100%))to measure the relative completeness of ***-Meier analysis assessed survival at 12 months by tertiles of rSYNTAX andΔSYNTAX%***ΔSYNTAX%score was associated with reduced in-hospital mortality(P=0.017),and improved survival benefit(log rank 14.8,P=0.001)at 12 *** Enhancing the completeness of revascularisation in octogenarians selected to undergo PCI is associated with a lower in-hospital mortality and a survival benefit at 12 months.
