Is the obesity paradox present in left ventricular assist device recipients? A BMI-based analysis

Global Cardiology
While body mass index (BMI) is a known determinant of cardiovascular outcomes, its impact on patients undergoing left ventricular assist device (LVAD) implantation remains unclear. This study aimed to evaluate the association between BMI and in-hospital

Evaluation of physiological control systems for rotary left ventricular assist devices: An in-vitro study

, 2016
Rotary left ventricular assist devices (LVADs) show weaker response to preload and greater response to afterload than the native heart. This may lead to ventricular suction or pulmonary congestion, which can be deleterious to the patient’s recovery.

Radial Versus Femoral Access for Diagnostic Coronary Angiography: Insights From a Tertiary Academic Center in Johannesburg

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The radial artery is the preferred access for performing diagnostic coronary angiograms (DCA). However, data on the safety and efficacy of radial compared to femoral access in low‐ and middle‐income countries is limited. Aims This study aims to evaluate the safety and efficacy of radial versus femoral access in patients referred for
