Background: Left distal transradial angiography (ldTRA) is a new technique for radial coronary angiography and may be an alternative to conventional transfemoral angiography (TFA) in patients who had previously undergone coronary artery bypass graft (CABG) surgery. In this study we compared ldTRA with TFA in patients who had undergone CABG surgery in terms of procedural details.

Methods: Fifty-seven consecutive patients with history of previous CABG among 459 patients who were admitted to coronary angiography unit (elective and acute coronary syndromes) in our center between October 2019 and February 2020 were included in the study.

Objective: It is still debatable whether diagnostic coronary angiography (CA) or percutaneous coronary interventions (PCIs) increase radiation exposure when performed via radial approach as compared to femoral approach. This question was investigated in this study by comparison of dose-area product (DAP), reference air kerma (RAK), and fluoroscopy time (FT) among radial and femoral approaches.

Methods: All coronary procedures between November 2015 and November 2017 were assessed; and 4215 coronary procedures were enrolled in the study.

Objective: Identification of the asymptomatic target organ damage (AOD) helps to stratify the overall risk of cardiovascular (CV) diseases and guides a treatment decision in hypertensive patients without a symptomatic CV or renal disease. The endothelial-cell-specific molecule 1 (endocan) is regarded as a novel marker of endothelial dysfunction. Its release is increased in hypertensive patients, especially those with symptomatic CV and renal disease.

The left internal mammary artery (LIMA) is widely used in coronary artery bypass grafting surgery due to its long term perfect patency rates. However, coronary steal syndrome can occur because of unligated LIMA side branches and it causes blood flow from coronary artery to LIMA. Even though the optimal therapy of coronary steal syndrome is still controversial, some percutaneous and surgical treatment modalities can be used in the treatment of steal phenomenon for relieving angina and resolving ischemia.

Aim: Transradial access (TRA) for coronary intervention is increasingly used in current clinical practice. The aim of the present study was to evaluate the hypothesis that cutaneous analgesia before TRA for coronary intervention at a puncture site 30 minutes before puncture can reduce patient discomfort and the incidence of radial artery spasm (RAS).

Methods: Patients (n=104) undergoing planned coronary interventions using TRA were prospectively randomized to receive either 1 mL of 1% lidocaine subcutaneously (n=52) (control group) or subcutaneous lidocaine plus 5% lidocaine cream (n=52) cutaneously 30 minutes before puncture (treatment group).
