CT findings of right heart failure before TAVR predicts mortality, finds study
USA: Imaging features of right heart failure seen on CT performed before TAVR is associated with increased death risk within the first year after TAVR, according to a recent study published in the American Journal of Roentgenology. The imaging findings can help in further risk stratification of patients before TAVR.
The purpose of this study by Rydhwana Hossain, University of Maryland School of Medicine, Baltimore, MD, and colleagues, is to determine whether imaging features of right heart failure seen on CT performed before transcatheter aorta valve replacement (TAVR) predict poor outcomes after the procedure.
The researchers retrospectively evaluated findings on CT before TAVR for 505 patients. Of these, 300 patients underwent TAVR. Patient demographic characteristics and clinical and procedural data were recorded. Then they evaluated imaging features including signs of left heart failure, right heart failure, coronary artery disease, lung disease, and apparatus calcifications and concomitant mitral valve.
