Comparative StudyDirect transcatheter aortic valve implantation with self-expandable bioprosthesis: feasibility and safety.
Balloon valvuloplasty has been considered a mandatory step of the transcatheter aortic valve implantation (TAVI), although it is not without risk. The aim of this work was to evaluate the feasibility and safety of TAVI performed without pre-dilation (direct TAVI) of the stenosed aortic valve. ⋯ Compared to TAVI with pre-dilation, direct TAVI is feasible regardless of the presence of bulky calcified aortic valve and the valve size implanted. Device success was higher in direct TAVI, mostly driven by a lower incidence of paravalvular leak. Safety at 30 days was similar in two groups.

Comparative Study Observational StudyOperator learning curve for transradial percutaneous coronary interventions: implications for the initiation of a transradial access program in contemporary US practice.
Our study aimed to assess the characteristics and outcomes of transfemoral approach (TFA) versus the initial steps of a transradial approach (TRA) program and to assess the learning curve of TRA in contemporary, US practice. ⋯ Adopting TRA as a default is feasible for high-volume operators without significant learning curve effects.

Randomized Controlled Trial Multicenter Study Comparative StudyRandomized comparison of operator radiation exposure comparing transradial and transfemoral approach for percutaneous coronary procedures: rationale and design of the minimizing adverse haemorrhagic events by TRansradial access site and systemic implementation of angioX - RAdiation Dose study (RAD-MATRIX).
Radiation absorbed by interventional cardiologists is a frequently under-evaluated important issue. Aim is to compare radiation dose absorbed by interventional cardiologists during percutaneous coronary procedures for acute coronary syndromes comparing transradial and transfemoral access. ⋯ The RAD-MATRIX study will probably consent to clarify the radiation issue for interventional cardiologist comparing transradial and transfemoral access in the setting of acute coronary syndromes.

Comparative StudyUse of emergency medical services expedites in-hospital care processes in patients presenting with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.
To determine whether door-to-balloon (DTB) times of patients presenting with ST-elevation myocardial infarction (STEMI) were reduced in patients transported by emergency medical services (EMS) compared to those who were self-transported. DTB time is an important measure of hospital care processes in STEMI. Use of EMS may expedite in-hospital processing and reduce DTB times. ⋯ Independent correlates of DTB times >90 minutes were self-transport (odds ratio 5.32, 95% CI 2.65-10.70; p<0.001) and off-hours presentation (odds ratio 2.89, 95% CI 1.60-5.22; p<0.001). Use of EMS transport in STEMI patients significantly shortens time to reperfusion, primarily by expediting emergency department processes. Community education efforts should focus not only on the importance of recognizing symptoms of myocardial infarction, but also taking early action by calling the EMS.
