Aims: Few data are available regarding the role of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), a measurement of right ventricular to pulmonary artery coupling, in patients with chronic heart failure and left ventricular systolic dysfunction.
Methods And Results: This retrospective single-centre study included outpatients with left ventricular systolic dysfunction (ejection fraction ≤ 50%) evaluated between January 2022 and December 2022. TAPSE/PASP was evaluated as a continuous variable and as tertiles according to its value on the first visit.
Background: Klippel-Feil disease is a condition characterized by a defect in the spine, consisting of the fusion or non-separation of two or more vertebrae of the cervical tract. It affects 1 in every 50,000 newborns, and the pathogenesis remains unknown to date, although the role of certain genes that are involved in segmentation processes is being studied. A single case of a genetic Myosin Heavy Chain 3 () mutation is described here.
