Abstract

Background: Low Body Mass Index (BMI) is associated with poor outcomes in patients who undergo various cardiac interventions. Studies on patients with elevated BMI have produced mixed results. Our study aims to evaluate the impact of obesity on the in-hospital outcomes of patients undergoing transcatheter mitral valve repair using MitraClip in the United States.

Methods: The National Inpatient Sample (NIS) database (2016-2020) was analyzed to identify patients who underwent transcatheter mitral valve repair using MitraClip. Patients less than 18 years, with protein-energy malnutrition and rapid weight loss, were excluded. Our final study population was classified into Obese (BMI ≥ 30 Kg/m²) and Non-obese (Normal/Overweight) (BMI 0f 18.5 -29.9 Kg/m²) cohorts based on their Body Mass Index (BMI). The primary outcomes were the prevalence of obesity and in-hospital mortality. Secondary outcomes were the rate of periprocedural complications, including cardiogenic shock, cardiac arrest, myocardial infarction, and acute kidney injury.

Result: 40,950 patients underwent transcatheter mitral valve repair (MitraClip) during our study period. 7.8% were identified as obese. Obese patients were more likely to be female (50.6% vs. 43.9%, p

Conclusions: Our study suggests obesity does not influence short-term in-hospital outcomes in patients undergoing transcatheter mitral valve repair using MitraClip.
