Unprotected left main angioplasty in nonagenarians: clinical characteristics, procedural features and outcome: a case series study.
Limited information is available on clinical characteristics and outcomes in very old patients with unprotected left main coronary artery disease (ULMCA) undergoing percutaneous coronary intervention (PCI).


METHODS
From January 2004 and December 2008, 248 patients with ULMCA stenosis underwent coronary revascularization with stent implantation. Among those, 6 were older than 90 years at the time of the procedure and were included in this study.


RESULTS
There were 5 males and 1 female; mean age was 91.5 years (range 91-93). All the patients presented with acute coronary syndromes. All of them had multivessel disease with a distal left main stenosis in 4 patients. All were deemed inoperable, with a mean EuroSCORE of 12.66 (range 10-20) and a predicted mortality at 34% (range15.8-86.6%). 5 patients received bare-metal stents and 1 patient a paclitaxel-eluting stent. Rotational atherectomy was required in 2 patients. Provisional side branch T-stenting with final kissing balloons was the technique used in all bifurcation lesions. Angiographic success was obtained in all patients. There were no in-hospital deaths or complications. After a 29.8-month (range 8-59) mean follow up period, a myocardial infarction caused by late stent thrombosis occurred in 1 patient and ischemia-driven target vessel revisualization was required in another; however, all patients were alive.


CONCLUSIONS
In the very elderly patients at excessively high risk for surgery, PCI for ULMCA disease is a suitable alternative with excellent short-term results and acceptable long-term outcomes.
