“…Thus, a transcatheter aortic valve implantation (TAVI) could have been proposed. Since the first clinical report in 2002, TAVI has emerged as a valuable, less invasive and safe therapeutic alternative in patients with severe AS [8] , but it is not performed in the Brazilian Public Health System yet. Currently, the great advantage of TAVI over conventional valve replacement is the decrease in morbidity and mortality rates, especially for high-risk patients.…”

Heyde syndrome manifests as aortic stenosis associated with gastrointestinal bleeding. We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement. The prosthesis used depends on the characteristics of each patient and valve replacement allows the resolution of bleeding in most cases. Gastrointestinal bleeding in patients with aortic stenosis is associated with severity of the valve obstruction. A mechanical prosthesis was used with no recurrent bleeding even with the need for lifelong anticoagulation therapy.

“…The cause can be functional or anatomical. 13,14 Increased parasympathetic tone or disruption of the sodium channels can precipitate the block. 12 VZV myocarditis could lead to cardiac conduction disturbances and supraventricular, later ventricular, arrhythmias.…”

“…The implantation of a permanent pacemaker for therapeutic purposes in various brady-arrhythmias is now also an option in horses and could potentially have been applied in this case as well [ 35 , 36 ]. In humans, the close proximity of the subaortic outflow tract to the AV node makes aortic damaging a possible contributor to both intermittent and complete heart block [ 32 , 37 ], where also a difference in AV nodal anatomy may increase the susceptibility to AV nodal injury [ 33 ]. This may also be the case for horses, although to the authors’ knowledge no previous reports exist of cases in horses where cartilage in the subaortic region is so pronounced that it may interfere with cardiac conduction.…”

Second-degree atrioventricular (AV) block is the most common cardiac arrhythmia in horses, affecting 40–90% depending on breed. Usually, the AV blocks occur while the horses are resting and disappear upon exercise and are, therefore, considered to be uneventful for horses. However, if the AV blocks occur frequently, this may result in syncope and collapse. Identifying the cause of second-degree AV block is difficult and often subscribed to high vagal tone. In this report, we present an eight-year-old Quarter horse with a high burden of second-degree AV blocks and multiple collapses. The clinical examination, including neurological examination, blood analysis, 24-h ECG recording and cardiac echocardiography, did not reveal any signs of general or cardiovascular disease besides a high burden of second-degree AV blocks (~300 blocks per hour) and a hyperechoic area in the AV nodal region. An implantable loop recorder (ILR) was inserted to monitor the cardiac rhythm. The ILR detected several consecutive second-degree AV blocks and pauses above 5 s. However, unfortunately, no recordings were available during the collapses. Eventually, the horse was euthanized and the heart inspected. The aortic root was severely cartilaginous and appeared to penetrate the AV node, especially in the His bundle region, possibly explaining the hampered AV conduction. Nevertheless, it is still uncertain if the AV nodal disruption caused the collapses and more knowledge on AV nodal diseases in horses is warranted.
