Alcohol septal ablation for hypertrophic obstructive cardiomyopathy: do mitral valve leaflet length, septal thickness, or sex affect the outcome?

This retrospective cohort study aimed to assess whether basal septal wall thickness (BSWT), anterior (AML) and posterior (PML) mitral leaflet length, or sex were associated with remaining left ventricular outflow tract obstruction (LVOTO) in patients with hypertrophic obstructive cardiomyopathy (HOCM) undergoing alcohol septal ablation (ASA). One hundred fifty-four patients who underwent ASA at the Karolinska University Hospital in Stockholm, Sweden, between 2009 and 2021, were included retrospectively. Anatomical and hemodynamic parameters were collected from invasive catheterization before and during ASA, and from echocardiography (ECHO) examinations before, during, and at 1-year follow-up after ASA.

Risk assessment in patients with symptomatic and asymptomatic pre-excitation.

Aims: Controversy remains as to whether the exercise stress test (EST) is sufficient for risk evaluation in patients with pre-excitation. This study aims to clarify the usefulness of EST in risk stratification in both asymptomatic and symptomatic patients presenting with pre-excitation.

Methods And Results: This prospective study includes consecutive asymptomatic and symptomatic patients with pre-excitation referred for risk assessment.

[Cosmetic breast implants can influence cardiac imaging].

Cosmetic breast implants are increasing in popularity. The presence of foreign material overlying the anterior wall of the heart can influence cardiac imaging and lead to misdiagnosis of cardiac disease.  Echocardiography is commonly used in patients for evaluation of cardiac structure and function.

Aerobic exercise capacity is maintained over a 5-year period in mild-to-moderate chronic kidney disease: a longitudinal study.

Background: Aerobic exercise capacity is reduced in non-dialysis chronic kidney disease (CKD), but the magnitude of changes in exercise capacity over time is less known. Our main hypothesis was that aerobic ExCap would decline over 5 years in individuals with mild-to-moderate CKD along with a decline in renal function. A secondary hypothesis was that such a decline in ExCap would be associated with a decline in muscle strength, cardiovascular function and physical activity.

Cardiovascular changes in patients with mild-to-moderate chronic kidney disease compared with healthy subjects: a 5-year follow-up study.

Background: There is limited knowledge about how cardiovascular parameters change over time in patients with mild-to-moderate chronic kidney disease (CKD). We studied several cardiovascular biomarkers over a 5-year period in patients with mild-to-moderate CKD and in healthy controls.

Methods: Fifty-four patients with CKD stages 2-3 and 54 controls were included.
