Real-world application of CCTA with CT-FFR for coronary assessment pre-TAVI: the CT2TAVI study.
Int J Cardiovasc Imaging
January 2025
Cardiology, Endeavor NorthShore Cardiovascular Institute, Evanston, IL, USA.
This study aims to evaluate the implementation of concomitant CAD assessment on pre-TAVI (transcatheter aortic valve implantation) planning CTA (CT angiography) aided by CT-FFR (CT-fractional flow reserve) [The CT2TAVI protocol] and investigates the incremental value of CT-FFR to coronary CT angiography (CCTA) alone in the evaluation of patients undergoing CT2TAVI. This is a prospective observational real-world cohort study at an academic health system on consecutive patients who underwent CTA for TAVI planning from 1/2021 to 6/2022. This represented a transition period in our health system, from not formally reporting CAD on pre-TAVI planning CTA (Group A) to routinely reporting CAD on pre-TAVI CTA (Group B; CT2TAVI protocol).

Purpose: Somatostatin receptor (SSTR)-PET is crucial for effective treatment stratification of neuroendocrine neoplasms (NENs). In highly proliferating or poorly differentiated NENs, dual-tracer approaches using additional [F]FDG PET can effectively identify SSTR-negative disease, usually requiring separate imaging sessions. We evaluated the feasibility of a one-day dual-tracer imaging protocol with a low activity [F]FDG PET followed by an SSTR-PET using the recently introduced [F]SiFAlin-TATE tracer in a long axial field-of-view (LAFOV) PET/CT scanner and its implications in patient management.

Department of Cardiology, National Center for Cardiovascular Diseases, Fuwai Hospital, Chinese Academy of Medical Sciences, Beijing, China.
Aim: To evaluate the safety of brachial artery (BA) sheath removal after heparin neutralization with a half dose of protamine immediately after percutaneous coronary intervention (PCI).
Methods: The clinical data of 209 consecutive patients who underwent PCI through the BA at Fu Wai Hospital between September 2019 and June 2024 were retrospectively collected. In group I, the brachial sheath was removed 4 h after the PCI procedure.
The design and rationale of the cardiac REHABilitation to improve metabolic health in Hypertrophic CardioMyopathy (REHAB-HCM) Study.

Division of Cardiology, Department of Medicine, University of British Columbia, Vancouver, British Columbia, Canada.
Study Objective: Hypertrophic cardiomyopathy (HCM) is the most common genetic myocardial disorder increasingly characterized by concomitant metabolic syndrome. Cardiac rehabilitation (CR) has been shown to improve metabolic parameters in populations with heart failure and myocardial infarction. However, there is a paucity of data on the impact of CR in the HCM population with metabolic syndrome.

In clinical practice, ventricular ejection fraction (EF) and global longitudinal strain (GLS) are the most often used parameters for evaluating left ventricular systolic function, despite the impact that variable loading conditions have. Alternatively, the myocardial efficiency (ME) of the heart, encompassing cardiac energy formation and dissipation, along with myocardial oxygen consumption (MVO
