Guideline-directed medical therapy for heart failure in arrhythmia-induced cardiomyopathy with improved left ventricular ejection fraction.

Aims: No study has analyzed the impact of guideline-directed medical therapy in preventing heart failure (HF) relapse in patients with arrhythmia-induced cardiomyopathy (AiCM) following left ventricular ejection fraction (LVEF) improvement.

Methods And Results: We analyzed data from a single-center cohort of 200 patients admitted for HF, LVEF <50% and cardiac arrhythmia considered by cardiologists to be the precipitating cause of the episode. The primary endpoint was time-to-HF relapse, defined as the composite of readmission for HF, Emergency Department (ED) visit for HF, or significant decline in LVEF.

Tricuspid Valve S-Curves and Chamber Views: Implications for Transcatheter Tricuspid and Pulmonary Valve Interventions, Part 2 of the S-Curves and Chamber Views Series.

Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.

Burden of Mitral Regurgitation in Spain from 2016-2021: An Analysis by Aetiology and Sex.

: Mitral regurgitation (MR) is the second most common valve disease in Europe, and differences between men and women have been described in relation to aetiology or management, which might impact the decision for intervention and patients' clinical and economic outcomes. Thus, the objective was to analyse the burden of MR in Spain by aetiology and sex, and the management of all patients suffering from MR being admitted to hospital between 2016-2021. : An analysis was carried out with the Ministry of Health's database, including all patients in public and subsidised hospitals and defining two groups, general MR and those patients undergoing Transcatheter Edge-to-Edge repair (TEER), using a descriptive analysis of patients' characteristics, use of resources, and outcomes; standardised rates were calculated and observed outcomes were described.

Applicability of heart failure clinical practice guidelines in low- and middle-income countries.

Aims: Clinical practice guidelines are commonly written by professional societies in high-income countries (HIC) with limited anticipation of implementation obstacles in other environments. We used heart failure (HF) guidelines as a paradigm to examine this concern, by conducting a survey to understand clinicians' ability to implement HF guidelines and their perceptions of the current HF guideline applicability in low- and middle-income countries (LMIC).

Methods And Results: An online survey of physicians in the database of the Translational Medicine Academy who treat HF patients was offered by email from 5 October to 27 November 2023, inquiring of participants' demographic information, experience, and views of HF guidelines as related to their practice.
