This study aimed to validate the increased wall thickness (IWT) score, a multiparametric echocardiographic score to facilitate diagnosis of cardiac amyloidosis (CA), in an independent population of patients with increased LV wall thickness suspicious for CA. ⋯ This study reports the first external validation of the IWT score for the diagnosis of CA in patients with increased LV wall thickness. A score ≥ 8 showed a high Sp, PPV and PA, suggesting that the IWT score can be used to identify CA patients in those with increased LV wall thickness.

Multicenter Study Observational Study
Optimal hemostasis duration for percutaneous coronary intervention via the snuffbox approach: A prospective, multi-center, observational study (HEMOBOX).
Percutaneous coronary intervention (PCI) via the distal radial access (DRA), called as snuffbox approach, recently has been increased worldwide due to fewer complications. Generally, since the diameter of distal radial artery is smaller than the radial artery, it is expected that the hemostasis duration can be shortened; however, there are no prospective studies. Furthermore, there is a lack of data about the feasibility of DRA for PCI. ⋯ HEMOBOX trial first reported hemostasis duration for PCI using the DRA, approximately 3 h, with 99.2% success rate and few minor complications.
