According to the Valve Academic Resortium, underweight is one parameter in the definition of frailty, which is associated with increased mortality after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). Aims of our study were (1) to examine the impact of underweight on mortality after TAVI and SAVR and (2) to determine the effect of intervention mode (TAVI vs SAVR) on mortality in underweight patients from the German Aortic Valve Registry. Overall, 35,109 patients treated with TAVI or SAVR were studied. ⋯ Subgroup analysis of severely underweight patients (BMI <18.5 kg/m²) revealed no significant increase of mortality after TAVI compared with underweight patients (BMI <20 kg/m2), whereas severely underweight SAVR patients showed twofold increased mortality rates. In conclusion, underweight in patients who underwent TAVI or SAVR is rare, but it is associated with increased mortality. Especially severely underweight SAVR patients showed excess mortality rates.

The Center for Medicare & Medicaid Services has identified readmission as an important quality metric in assessing hospital performance and value of care. The aim of this study was to quantify the impact of "care fragmentation" on transcatheter aortic valve implantation (TAVI) outcomes. Readmission to nonindex hospitals was defined as any hospital other than the hospital where the TAVI was performed. ⋯ Despite the high co-morbidity burden of patients readmitted to nonindex hospitals, unadjusted and risk-adjusted all-cause mortality, readmission length of stay and total hospital costs following nonindex readmission were lower compared with index readmission at 90 days. In conclusion, in this real world, nationally representative cohort of TAVI patients in the United States, care fragmentation remains prevalent and represent an enduring, residual target for future health policies. Although the impactful readmissions may be directed toward index hospitals, concerted efforts are needed to address mechanisms that increase care fragmentation.

Meta Analysis
Meta-Analysis of the Usefulness of Inferior Vena Cava Filters in Massive and Submassive Pulmonary Embolism.
To conduct a systematic review and meta-analysis evaluating the safety and effectiveness of inferior vena cava filter (IVCF) placement in the setting of massive and submassive pulmonary embolism (PE), Pubmed and Cochrane Library were queried to identify all clinical studies evaluating IVCF placement in patients with massive and submassive PE from database establishment to December 2019. The rate of recurrent PE, PE-related mortality, adverse events, IVCF type, additional treatment intervention, DVT status, and follow-up length were retrieved. Recurrent PE, mortality, and complication rates were pooled. ⋯ The cumulative IVCF-related complication rate was 0.63%. In conclusion, based on a limited amount of low-quality evidence, IVCF placement is associated with low recurrent PE and PE-related mortality rates among patients with massive and submassive PE, suggestive of a potential clinical benefit in this scenario. Prospectively designed studies are warranted to confirm these findings.

The Marfan syndrome (MFS) patients are highly predisposed to thoracic aortic aneurysm and/or dissection, with virtually every patient having evidence of aortic disease at some point during their lifetime. We conducted a meta-analysis to investigate the efficacy of angiotensin receptor blockers (ARBs) in slowing down the progression of aortic dilatation in MFS patients. PUBMED, EMBASE, and COCHRANE databases were searched for relevant articles published from inception to February 1, 2020. ⋯ ARBs as an add-on therapy to beta-blockers resulted in a significantly smaller change in aortic root dilation when compared with the arm without ARBs (mean difference -2.06, 95% CI -2.54 to -1.58; p < 0.00001, I2 = 91%). However, there was no statistically significant difference in the number of clinical events (aortic complications/surgery) observed in the ARBs arm when compared with placebo (Risk ratio of 1.01, 95% CI 0.74 to 1.38; p = 0.94, I2 = 0%). In conclusion, ARBs therapy is associated with a slower progression of aortic root dilation when compared with placebo and as an addition to beta-blocker therapy.

Coronavirus disease 2019 (COVID-19) has become a global pandemic. It is still uncontrolled in most countries and no therapies are currently available. Various drugs are under investigation for its treatment. ⋯ Chloroquine/hydroxychloroquine, azithromycin, remdesivir and lopinavir/ritonavir are currently being studied in trials and show some promise. Conduction disorders, heart failure, and mortality have been reported with the use of these drugs. It is important to have knowledge of potential cardiotoxic effects of these drugs before using them for COVID-19 patients for better allocation of healthcare resources and improvement in clinical outcomes.
