Cost-effectiveness in unstable economies: the case of sacubitril/valsartan in heart failure with reduced ejection fraction in Argentina.

Background: Sacubitril/valsartan (an Angiotensin receptor-neprilysin inhibitor-ARNI) is one of the cornerstones in the management of patients with heart failure with reduced ejection fraction (HFrEF) having demonstrated significant reductions in both mortality and hospitalisations as compared with enalapril. It proved to be a cost-effective treatment in many countries with stable economies. In Argentina, a country with chronic financial instability and a fragmented health care system, the estimation of its cost-effectiveness requires to consider local financial data.

Real-world data meta-analysis: procedural success and clinical outcomes after radiofrequency ablation of atrial fibrillation in South America.

Objective: To profile patients' characteristics, in-hospital results, and recurrence rates after radiofrequency ablation of atrial fibrillation (RAAF) in South America.

Methods: We comprehensively searched for single-center studies from South America with ≥10 patients receiving RAAF, published or presented from January 1, 2010, through June 29, 2020, excluding those reports aimed to specific populations such as permanent atrial fibrillation, structural cardiopathies, or re-do procedures.

Results: Main pooled estimates from a random-effects meta-analysis that included 3909 patients from 27 cohorts (from 5 countries): a) Patients characteristics: age 57.

Temporal Trends in Self-Expandable Transcatheter Aortic Valve Replacement in South America: A Systematic Review and Meta-Analysis.

Objectives: This study aimed to estimate temporal trends in clinical presentation and short-term outcomes of transcatheter aortic valve replacement (TAVR) with self-expandable prostheses in South America through a systematic review and meta-analysis of observational data.

Methods: We comprehensively searched for articles published in peer-reviewed medical journals and for abstracts presented in medical conferences of the region from September 1, 2008, to June 29, 2020. We included single-center studies on self-expandable TAVR populations with ≥ 10 patients from South America.

Clinical outcomes after transcatheter aortic valve replacement in South America: A centre-level systematic review and meta-analysis of observational data.

Objectives: To estimate in-hospital and 30-day outcomes after transcatheter aortic valve replacement (TAVR) in South America through a systematic review and meta-analysis of observational data.

Methods: We comprehensively searched for papers published in peer-reviewed medical journals and for abstracts presented in medical conferences of the region from 1 September 2008, through 29 June 2020, using predefined criteria. We included single-centre studies on TAVR populations with ≥10 patients from South America reporting any in-hospital or 30-day clinical outcome.

Periprocedural adverse events in cell therapy trials in myocardial infarction and cardiomyopathy: a systematic review.

Background: Cell therapy (CTh) is a promising novel therapy for myocardial infarction (MI) and ischemic cardiomyopathy (iCMP). Recognizing adverse events (AE) is important for safety evaluation, harm prevention and may aid in the design of future trials.

Objective: To define the prevalence of periprocedural AE in CTh trials in MI and iCMP.
