RESUMEN
BACKGROUND: Although covered stents (CS) represent a potentially life-saving intervention for coronary perforation (CAP), their application has expanded to other contexts, including coronary aneurysms (CAA). However, data regarding mid- and long-term outcomes of CS in these settings scenarios remains limited. AIMS: This meta-analysis aims to evaluate major adverse cardiac events (MACE) from discharge through long-term follow-up in patients undergoing percutaneous coronary intervention with the new generation polyurethane-covered cobalt-chromium PK Papyrus CS. METHODS: We conducted a meta-analysis of data from three observational trials that included long-term follow-up of patients who underwent PK Papyrus CS implantation: Papyrus-Spain, SOS PK Papyrus, and PAST-PERF registry. RESULTS: 332 patients underwent PK Papyrus CS implantation, 236 (71.1%) for CAP, 70 (21.1%) for CAA and 26 (7.8%) for other indications. After a mean follow-up of 16.2 months, the MACE was 14.3%, with Target Lesion Revascularization (TLR) being the most frequent (8.5%), followed by stent thrombosis (ST), 3.3% and cardiac death (CD), 2.6%. Comparing CAP and CAA subgroups, the MACE rate in CAA was significantly higher than CAP (21.4% vs 9.7%, p < 0.01), primary driven by ST (CAA: 8.6% vs CAP: 1.3%; p = 0.0015). CONCLUSIONS: The clinical outcomes following PK Papyrus CS implantation are deemed acceptable, considering the challenging scenarios and the existing alternative treatments. However, MACE rates in patients with CAA who received Papyrus PK CS were significantly higher than in those with CAP, underscoring the importance of meticulous patient selection and optimization of CS in these complex patients and coronary anatomies.

Pulmonary prosthetic valve endocarditis (PPVE) is a rare condition. While antibiotic and anticoagulation therapy are commonly successful, in cases of treatment failure or severe valve damage, surgical intervention is often necessary. In critical patients, percutaneous intervention can play a crucial role in stabilizing the patient's clinical condition. We detail a bridge-to-surgery approach using percutaneous aspiration of endoprosthetic valve endocarditis followed by pulmonary valvuloplasty in a patient in shock needing ECMO support.
RESUMEN
There has been suggestion that vitamin D may play a role in protection against severe infection with COVID-19, defined as the need of intensive care unit admission. In this article a potential mechanism involving angiotensin-converting enzyme 2 (ACE2) is proposed.
