Vascular access: Femoral, radial and large-bore alternative access.

Vascular access for coronary, peripheral, and structural interventions has changed significantly over the past two decades. The evolving demand for both large-bore access for valvular interventions and mechanical support devices, and for safer access for coronary interventions, in patients with comorbidities have driven progress in these areas. This review will provide an overview of the techniques of arterial access in the femoral, forearm (radial and ulnar), and alternative (transcarotid, transaxillary, and transcaval) locations based on the latest evidence and experience.

Angiography-Derived Fractional Flow Reserve: Newer Data and Future Directions.

Several novel software systems have been developed for the reconstruction of the coronary artery tree and the calculation of fractional flow reserve (FFR) from coronary artery angiography images without coronary artery instrumentation: FFR, Computational pressure-flow dynamics derived FFR, quantitative flow ratio (QFR), and vessel FFR. In this report, we review the current evidence on each software, their contemporary use, and future directions.

Single-center analysis of cardiac amyloidosis using 99m Tc-HMDP imaging for diagnosis and evaluation after tafamidis treatment.

Objective: This study aimed to evaluate the diagnostic performance of 99m Tc-hydroxymethylene diphosphonate ( 99m Tc-HMDP) imaging for cardiac amyloidosis and to demonstrate changes in cardiac uptake of 99m Tc-HMDP after tafamidis treatment.

Methods: Seventy-five patients with suspected cardiac amyloidosis who underwent 99m Tc-HMDP imaging were included. We compared visual Perugini grades and semiquantitative heart-to-contralateral (H/CL) area ratios, myocardial maximum standardized uptake value (SUVmax), and peak of SUV (SUVpeak) between cardiac transthyretin amyloidosis (ATTR) and amyloid light-chain amyloidosis (AL).
