Short Durations of Radial Hemostatic Device After Diagnostic Transradial Cardiac Catheterization: The PRACTICAL-2 Randomized Trial.

Background: Radial artery occlusion (RAO) is the most common complication following transradial approach (TRA) for cardiac catheterisation. Our aim was to assess if decreasing radial hemostatic device (RHD) time reduces the risk of RAO among individuals receiving small sheath sizes with no adjunctive heparin.

Methods: We randomised 450 individuals undergoing diagnostic cardiac catheterization via TRA to 3 durations of RHD time: 10, 20, or 30 minutes.

Multimodality imaging for assessment of coronary embolus.

Caseous mitral annulus calcification involving aortomitral curtain is a rare occurrence. We report a case of a 64-year-old woman with end-stage renal failure and a candidate for renal transplant who presented with late ST-elevation myocardial infarction. Intracoronary imaging, computed tomography cardiac imaging, and histopathology confirmed coronary embolus into the left main stem artery from an extensive caseous mitral annulus calcification.

Obstructive sleep apnea and heart rate asymmetry microstructure during sleep.

Purpose: Heart rate decelerations and accelerations have unequal input to heart rate variability (HRV) and patterns created by consecutive cardiac cycles-this phenomenon is known as heart rate asymmetry (HRA). The analysis of monotonic runs of heart rate decelerations and accelerations provides a detailed insight into the HRA microstructure and thus of HRV.

Aim: To evaluate the relation between the severity of obstructive sleep apnea (OSA) and the HRA microstructure during sleep.
