Background: Severe calcification is the morphology most strongly associated with stent underexpansion.
Objectives: The aim of this study was to revise an optical coherence tomography (OCT)-derived calcium score to predict stent underexpansion in severely calcified lesions (angle >270°) using a point-based system.
Methods: A retrospective observational study was conducted in which 250 de novo lesions undergoing OCT-guided stenting, with angiographically visible calcium and optical coherence tomographic maximum superficial calcium angle >270°, not subjected to atherectomy or specialty balloon treatment before stent implantation, were randomly divided into derivation (n = 167) and validation (n = 83) cohorts.

A global treatment algorithm was developed for the endovascular revascularization of femoropopliteal lesions and chronic total occlusions, aiming toward a more standardized approach to endovascular treatment in patients with peripheral artery disease. The following steps are proposed. 1) Evaluation of lesion morphology based on preprocedural imaging by Duplex sonography and intravenous ultrasound for selection of lesion preparation tools.

A 71-year-old man with a history of atrial fibrillation presented to the emergency department with sudden unconsciousness after finishing lunch. Just 4 weeks ago, the patient underwent radiofrequency ablation for atrial fibrillation and regularly took rivaroxaban for anticoagulant therapy. According to the medical history, the patient suffered recurrent chest tightness and heartburn after radiofrequency ablation without other discomforts.

This updated Heart Valve Collaboratory framework addresses the growing concern for transcatheter valve failure (TVF) following transcatheter aortic valve replacement (TAVR). With the increasing volume of redo-TAV and surgical TAV explantation, there is a critical need for standardized pathways and protocols for evaluating TVF using echocardiography and cardiac computed tomography (CT) angiography. This document clarifies prior definitions of bioprosthetic valve deterioration and bioprosthetic valve failure in a practical, imaging directed context for TAVR.
