Multicenter Study Observational StudyImaging of Clinically Unrecognized Myocardial Fibrosis in Patients With Suspected Coronary Artery Disease.
Stress cardiac magnetic resonance (CMR) provides accurate assessment of both myocardial infarction (MI) and ischemia. ⋯ In a multicenter cohort of patients with suspected CAD, presence of UMI or RMI portended an equally significant risk for death and/or MI, independently of the presence of ischemia. Compared with RMI patients, those with UMI were less likely to receive guideline-directed medical therapies and presented an increased risk for heart failure hospitalization that warrants further study.

Multicenter StudyTranscatheter Valve-in-Valve Aortic Valve Replacement as an Alternative to Surgical Re-Replacement.
Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) and redo surgical aortic valve replacement (SAVR) represent the 2 treatments for aortic bioprosthesis failure. Clinical comparison of both therapies remains limited by the number of patients analyzed. ⋯ VIV TAVR was observed to be associated with better short-term outcomes than redo SAVR. Major cardiovascular outcomes were not different between the 2 treatments during long-term follow-up.
