Background: Left ventricular ejection fraction (LVEF) worsening after transcatheter aortic valve replacement (TAVR) was common in clinical practice. However, the effect of acute worsening LVEF is unclear.
Methods: All consecutive patients who underwent TAVR between January 2016 and May 2022 were analyzed. Patients were divided into worsened LVEF and non-worsened LVEF according to whether or not they had an LVEF decline of ≥5% at discharge. Survival at follow-up was compared between two groups. Logistic regression analysis was used to determine independent predictors of worsening LVEF.
Results: A total of 439 patients were included in the analysis, and 112 (25.5%) patients had worsened LVEF. Worsened LVEF was more common in patients with LVEF ≥50%. After multivariable logistic analysis, only baseline LVEF was associated with worsening LVEF [OR=1.06 (95% CI: 1.04-1.08), P < 0.001]. The decline in LVEF recovered to the baseline after one month. There were no significant differences in survival between patients with and without worsened LVEF (Log rank P = 0.48).
Conclusion: Acute worsening of LVEF after TAVR was not uncommon but did not affect survival. It could recover to baseline levels after one month. Routine post-TAVR echocardiography should focus on other metrics rather than acute LVEF changes.

Background: In systemic lupus erythematosus (SLE), ventricular dysfunction can occur from primary immune injury or secondarily from SLE-related co-morbidities. The aim of this study was to determine clinical predictors of reduced left ventricular (LV) systolic and diastolic function in an effort to understand potentially mitigating strategies.
Methods: We retrospectively studied 76 patients with SLE who had comprehensive transthoracic echocardiography within 3 months of an appointment with a rheumatologist to correlate clinical, laboratory, and echocardiographic features.

Introduction: Chronic kidney disease (CKD) is a complex pathophysiologic process that leads to irreversible changes in kidney structure and function. The left ventricle (LV) remodeling, which is evident as LV hypertrophy (LVH) is highly prevalent in patients with CKD even in the early stages and has a strong association with cardiovascular mortality, multiple studies have suggested that there is a strong association between high albuminuria and LVH, which was found to be independent of low GFR, hypertension, and diabetes. The most commonly used noninvasive method for estimating cardiac function and size is 2D echocardiography.

Background: Patients with severe heart failure (HF) experience debilitating clinical symptoms and worse cardiovascular (CV) outcomes with an excess mortality risk.
Objectives: The authors aimed to assess the prevalence, CV outcome risk, and treatment response to the sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin among patients with severe HF across the spectrum of left ventricular ejection fraction (LVEF) in DAPA-HF and DELIVER.
Methods: Severe HF was adapted from the ESC (European Society of Cardiology) HFA (Heart Failure Association) definition: NYHA functional class III/IV, evidence of HF with reduced, mildly reduced, or preserved LVEF, HF hospitalization within the previous 12 months, and adverse patient-reported symptom burden (Kansas City Cardiomyopathy Questionnaire-Total Symptoms Score <75).

Background: Radiation therapy (RT) improves breast cancer outcomes, but cardiac morbidity remains a concern.
Objectives: This study sought to evaluate changes in cardiac function after RT and the relationship between cardiac dose metrics and echocardiography-derived measures of function.
Methods: In a longitudinal cohort study of women with breast cancer, radiation cardiac dose metrics and core lab quantitated echocardiographic measures of cardiac function were evaluated.
Targeting Inflammation and Iron Deficiency in Heart Failure: A Focus on Older Adults.

: Heart failure (HF) is a leading cause of morbidity and mortality worldwide, with a higher prevalence among older adults. Iron deficiency (ID), affecting up to 50% of HF patients, is closely linked to chronic inflammation, exacerbating HF outcomes. This review aims to explore the interplay between inflammation, ID, and HF, focusing on older patients, and to identify therapeutic gaps and emerging treatment strategies.
