Background: Recent data have shown that systemic sclerosis (SSc) is a significant risk factor for coronary artery disease (CAD) and poorer cardiovascular outcomes in the setting of acute coronary syndrome. However, the morphological characteristics of CAD and the long-term cardiovascular outcomes in patients with concurrent SSc and CAD remain unclear.
Methods: We retrospectively investigated 3,300 patients with CAD who underwent percutaneous coronary intervention (PCI) without prior myocardial infarction or coronary artery revascularization. Laboratory, echocardiographic and angiographic characteristics, and clinical outcomes were compared between patients with and without SSc according to a 1:3 propensity score-matching analysis adjusted for patient demographics and comorbidities. The primary outcome was a composite of cardiac death, myocardial infarction, and stroke, and the secondary outcome was a composite of the primary outcome and heart failure hospitalization.
Results: Among all 3,300 patients, 17 (0.5 %) had SSc. The patients were classified into an SSc group (n = 17) and non-SSc group (n = 51) by propensity score matching. There were no significant differences in laboratory or echocardiographic parameters between the two groups. However, CAD tended to be more complex in the SSc group because of the higher proportion of left main trunk lesions (p = 0.100) and higher SYNergy between PCI with TAXUS™ and Cardiac Surgery (SYNTAX) score (p = 0.030). During a median follow-up of 3.1 years, patients with SSc more frequently experienced primary and secondary outcomes than those without SSc (both log-rank p < 0.02).
Conclusions: Among patients with CAD, long-term cardiovascular outcomes after PCI were poorer in those with than without SSc.

A Revised Optical Coherence Tomography-Derived Calcium Score to Predict Stent Underexpansion in Severely Calcified Lesions.
JACC Cardiovasc Interv
March 2025
Clinical Trials Center, Cardiovascular Research Foundation, New York, New York, USA; Division of Cardiology, Department of Medicine, Columbia University Medical Center/NewYork-Presbyterian Hospital, New York, New York, USA.
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.
Global Algorithm for the Endovascular Treatment of Chronic Femoropopliteal Lesions: An Interdisciplinary Expert Opinion Statement.
JACC Cardiovasc Interv
March 2025
Department of Cardiology and Vascular Medicine, West German Heart and Vascular Center, University of Duisburg-Essen, Essen, Germany.
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.

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.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) is an underdiagnosed chronic disease associated with progressive heart failure that results in impaired quality of life, repeated hospitalizations, and premature death. Acoramidis is a selective, oral transthyretin stabilizer recently approved by the U.S.
