Short- and long-term data showed that drug-eluting stents (DES) significantly decreased target vessel revascularization (TVR) and major adverse cardiac event (MACE) rates compared to bare-metal stents (BMS). However, conflicting long-term data remain for patients with ST-segment elevation myocardial infarction (STEMI). ⋯ Neither SES nor PES improved safety or efficacy as compared to BMS in a STEMI population at 6 years. After adjusting, the usage of SES resulted in a significant decrease in mortality, mortality/MI and MACE rates as compared to BMS, in contrast to the usage of PES. SES and PES have a similar effectiveness and safety profile, although very late stent thrombosis was more common with SES.

Transcatheter aortic valve implantation (TAVI) has become an accepted treatment option for severe aortic stenosis (AS) in high-risk individuals. Yet, current results are difficult to compare given the lack of standardized definitions. ⋯ The newly established VARC standardized definitions are useful for TAVI outcome reporting.

Comparative Study
Cardiac events after non-cardiac surgery in patients with previous coronary intervention in the drug-eluting stent era.
The peri-operative risk for patients with coronary drug-eluting stents (DES) who subsequently have non-cardiac surgery (NCS) is unclear. We performed this retrospective study of all patients in our institution who had coronary intervention and subsequent NCS from 2003 through December 2008 to evaluate the incidence of major adverse cardiac events (MACE) in patients who received DES compared to those who received bare-metal stents (BMS) or had percutaneous transluminal coronary angioplasty (PTCA) during the same time period. The main outcome measures were 30-day post-operative myocardial infarction, stent thrombosis, target vessel revascularization (TVR) and cardiac death. ⋯ Seven patients who had DES had TVR compared to 1 patient who had BMS and none who had PTCA (p = 0.41). Cardiac mortality occurred in 2 patients who had DES and none who had PTCA or BMS (p = 0.35). In conclusion, the 30-day MACE in patients who received coronary DES and undergone NCS were not significantly different compared to those who received BMS or had PTCA only, with a trend toward higher stent thrombosis in the DES group.
