Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of biodegradable polymer versus durable polymer sirolimus-eluting stenting in patients with acute st-elevation myocardial infarction undergoing primary percutaneous coronary intervention: results of the RESOLVE study.
Sirolimus-eluting stents (SES) with a biodegradable polymer coating have demonstrated promising results but have not been compared to SES with a durable polymer in high-risk patients. We compared the efficacy of these 2 stent types in patients with acute myocardial infarction (STEMI). ⋯ In patients undergoing primary PCI for STEMI, the use of biodegradable polymer SES was associated with noninferior 1-year rates of MACE compared with durable polymer SES.

The current use of Impella 2.5 in acute myocardial infarction complicated by cardiogenic shock: results from the USpella Registry.
To evaluate the periprocedural characteristics and outcomes of patients supported with Impella 2.5 prior to percutaneous coronary intervention (pre-PCI) versus those who received it after PCI (post-PCI) in the setting of cardiogenic shock (CS) complicating an acute myocardial infarction (AMI). ⋯ The results of our study suggest that early initiation of hemodynamic support prior to PCI with Impella 2.5 is associated with more complete revascularization and improved survival in the setting of refractory CS complicating an AMI.

Variability in maximal suggested door-in-door-out time for hospitals transferring patients for primary angioplasty in STEMI.
We derived a formula for maximal suggested door-in-door-out time (DIDO) for hospitals that do not perform primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). ⋯ Transferring hospitals' maximal suggested DIDO is variable, and can be calculated from inter-hospital transport time. Instead of a universal target DIDO (e.g., <30 minutes), maximal suggested DIDO can be calculated individually for each non-PCI hospital within a STEMI network.

High bolus dose tirofiban has been demonstrated to provide greater inhibition of platelet aggregation, but the most appropriate timing of its administration remains unknown. ⋯ To the Chinese patients with acute myocardial infarction undergoing primary PCI, upstream administration of tirofiban was slightly superior to deferred injection for short-term clinical outcomes.

There are limitations of using 2D imaging to accurately size the aortic annulus. This article highlights the limitations of 2D technology and proposes a new 3D TEE method for sizing of the aortic annulus. ⋯ The method described in this article is complementary to multidetector computed tomography and provides a real-time measurement of the annulus during the TAVR procedure without need for radiographic contrast.
