Shokr M, Adegbala O, Elmoghrabi A, et al. - Researchers used the National Inpatient Sample and examined how the outcomes of transcatheter valvular procedures such as aortic valve implantation (TAVI), MitraClip, permanent pacemaker (PPM), implantable-cardioverter defibirillator (ICD), cardiac resynchronization therapy (CRT), left atrial appendage closure and pericardiocentesis in patients (age ≥ 18 years) can be influenced by the presence of chronic thrombocytopenia (cTCP). Two matched groups were derived using a propensity score matching model. A higher risk of complications following TAVI, MitraClip, PPM, ICD, CRT, left atrial appendage closure and pericardiocentesis was observed in cTCP patients. These patients had a 1.5-fold increased risk of in-hospital mortality, as well as greater health-care cost ($47,163 vs $35,763) and longer hospital stay.
