Multicenter Study Comparative StudyAfrican-American patients are less likely to receive drug-eluting stents during percutaneous coronary intervention.
Previous research has shown that African-Americans, patients without insurance, and those with government-sponsored insurance are less likely to be referred for invasive cardiovascular procedures. We therefore sought to compare the impact of race and insurance type upon the use of drug-eluting stents (DES). ⋯ This study is a retrospective analysis of the impact of race and insurance status upon the utilization of drug-eluting stents. Multivariable logistic regression showed that African-American race was associated with less utilization of drug-eluting stents.

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.
