Hemodynamic stabilization is crucial in managing acute cardiac events, where compromised blood flow can lead to severe complications and increased mortality. Conditions like decompensated heart failure (HF) and cardiogenic shock require rapid and effective hemodynamic support. Current mechanical assistive devices, such as intra-aortic balloon pumps (IABP) and extracorporeal membrane oxygenation (ECMO), offer temporary stabilization but are limited to short-term use due to risks associated with prolonged blood contact.

Arterial hypertension in young adults, which includes patients between 19 and 40 years of age, has been increasing in recent years and is associated with a significantly higher risk of target organ damage and short-term mortality. It has been reported that up to 10% of these cases are due to a potentially reversible secondary cause, mainly of endocrine (primary aldosteronism, Cushing's syndrome, and pheochromocytoma/paraganglioma), renal (renovascular hypertension due to fibromuscular dysplasia and renal parenchymal disease), or cardiac (coarctation of the aorta) origin. It is recommended to rule out a secondary cause of high blood pressure (BP) in those patients with early onset of grade 2 or 3 hypertension, acute worsening of previously controlled hypertension, resistant hypertension, hypertensive emergency, severe target organ damage disproportionate to the grade of hypertension, or in the face of clinical or biochemical characteristics suggestive of a secondary cause of hypertension.

Background: Interleaflet haemorrhage (IH) plays a well-recognized detrimental role in calcified aortic valve disease (CAVD). However, IH-induced fibro-osteogenic responses in valvular interstitial cells (VICs) appear to be triggered under specific pathological conditions. Iron deficiency (ID), a common co-morbidity in CAVD, may influence these responses.

The need for a permanent pacemaker (PPM) implantation after surgical aortic valve implantation (SAVR) is a recognized postoperative complication, with potentially long-term reduced survival. From 1987 to 2017, 2500 consecutive patients underwent SAVR with a biological valve with or without concomitant procedures such as CABG or mitral valve repair. Mechanical valves or valves in another position were excluded.

Elderly patients with severe aortic stenosis (AS) need individualized decision-making in their management in order to benefit in terms of survival and improvement of quality of life. Frailty, a common condition in elderly patients, needs to be considered when weighing treatment options. We aimed to evaluate outcomes including survival and functional parameters according to disability criteria at six years of follow-up in an older population treated for severe AS using a frailty-based management.
