Background:
The increasing number of transcatheter aortic valve implantation (TAVI) in the last few years has unveiled a unique set of events and complications that need prompt recognition and management in order to improve patient outcomes, often involving a multidisciplinary team.
Case Summary:
We present a case of a 86-year-old woman with symptomatic severe aortic stenosis that underwent a TAVI and, in the post-procedure period, presented with acute abundant haematemesis, haemodynamic instability, and haemoglobin drop. The diagnosis of acute necrotizing oesophagitis (ANE) was made by upper gastrointestinal endoscopy.
Discussion:
Acute necrotizing oesophagitis is a rare entity caused usually by an ischaemic insult in the presence of predisposing factors; it has a high rate of complications and mortality. To the best of our knowledge, this is the first clinical case report to describe the occurrence of ANE as a possible complication of TAVI and is also an example of the importance of the multidisciplinary approach of these complex patients, which extends even beyond the concept of Heart Team.

Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
