May 2024

First Department of Cardiology, Medical School, National and Kapodistrian University of Athens, Hippocration General Hospital, 115 27 Athens, Greece.

Article Synopsis
  • Patent foramen ovale (PFO) is a leftover from fetal circulation that affects about 25% of people but usually doesn’t cause symptoms.
  • PFO can be significant in conditions like cryptogenic stroke and migraines, and recent trials show that closing it through a procedure may be better than just medication for preventing strokes in specific patients.
  • The effectiveness of closure for other issues related to PFO, like decompression sickness and migraines, is still being studied, and the review will cover the current understanding of these aspects.

Obesity and Transcatheter Aortic Valve Replacement.

J Cardiovasc Dev Dis

May 2024

Section of Cardiovascular Medicine, Lawrence Memorial Hospital & Northeast Medical Group, Yale New Haven Heath, New London, CT 06614, USA.

Amidst an aging population and escalating obesity prevalence, elucidating the impact of obesity on transcatheter aortic valve replacement (TAVR) outcomes becomes paramount. The so-called "obesity paradox"-a term denoting the counterintuitive association of obesity, typically a risk factor for cardiovascular diseases, with improved survival outcomes in TAVR patients relative to their leaner or normal-weight counterparts-merits rigorous examination. This review comprehensively investigates the complex relationship between obesity and the clinical outcomes associated with TAVR, with a specific focus on mortality and periprocedural complications.

Right heart failure (RHF) following implantation of a left ventricular assist device (LVAD) is a common and potentially serious condition with a wide spectrum of clinical presentations with an unfavourable effect on patient outcomes. Clinical scores that predict the occurrence of right ventricular (RV) failure have included multiple clinical, biochemical, imaging and haemodynamic parameters. However, unless the right ventricle is overtly dysfunctional with end-organ involvement, prediction of RHF post-LVAD implantation is, in most cases, difficult and inaccurate.
