The combination of severe aortic stenosis, bleeding due to Heyde's syndrome and critical coronary artery disease presents a management challenge. We report the case of an 86-year-old who underwent percutaneous coronary intervention to the right coronary artery, simultaneous balloon aortic valvuloplasty to treat aortic stenosis and address bleeding from Heyde's syndrome, and subsequent staged transcatheter aortic valve implantation. < The combination of severe aortic stenosis (AS), bleeding due to Heyde's syndrome and critical coronary artery disease presents a management challenge.

Aortic valve stenosis associated with angiodysplasia (Heyde's syndrome) and consequent anemia had previously been reported to benefit from surgical aortic valve replacement. In this clinical case an 89-year-old patient with chronic angiodysplasia-derived anemia, characterized by acute phases of active gastrointestinal bleeding experienced a normalization of hemoglobin values after a trans-catheter aortic valve implantation (TAVI) of a self-expandable aortic valve prosthesis (CoreValve, Medtronic Inc., Minneapolis, MN, USA).

The harmful algal blooms are becoming increasingly problematic in the regions that drinking water production depends on surface waters. With a global occurrence, microcystins are toxic peptides produced by multiple cyanobacterial genera in the harmful algal blooms. In this study, we examined the effects of microcystin-LR (MC-LR), a representative toxin of the microcystin family, on vascular development in zebrafish and the apoptosis of human umbilical vein endothelial cells (HUVECs).

Background: Gastrointestinal bleeding (GIB) is one of the principal adverse events affecting patients with continuous-flow left ventricular assist devices (CF-LVADs). Despite the early recognition that GIB is commonly because of gastrointestinal angiodysplasia (GIAD), the exact pathophysiology of this process remains elusive. It has been postulated that the abnormal hemodynamic profile in CF-LVAD patients may activate the angiogenesis signaling cascade via the HIF (hypoxia-inducible factor)-1α/angiopoietin-2 pathway leading to formation of GIADs.

The von Willebrand factors (VWFs) play critical role in hemostasis and thrombosis formation. VWFs are produced in and secreted as large multimers from endothelial cells, and shear stress-dependently cleaved into 2-80 multimers by their specific protease, ADATS13. Because high molecular weight VWFs play important roles in platelet aggregation, the loss of high molecular weight VWFs caused by pathological high-shear stress induces a hemostatic disorder known as acquired von Willebrand syndrome (AVWS) type IIA.

Parkes-Weber syndrome is a congenital vascular disease that comprises capillary, venous, lymphatic, and arteriovenous malformations. Although Parkes-Weber syndrome is a clinically distinct entity with serious complications, it is still frequently misdiagnosed as Klippel-Trenaunay syndrome, which consists of a triad of malformations involving the capillary, venous, and lymphatic vessels, without arteriovenous fistulas. Both syndromes are generally diagnosed with Doppler ultrasound and confirmed by magnetic resonance angiography. Read More

Further discovery of mechanisms and the ubiquity and severity of acquired von Willebrand syndrome in the left ventricular assist device therapy have removed any doubts. At this time, gastrointestinal bleeding from intestinal angiodysplasia in patients with turbulence-related proteolysis of the highest molecular weight multimers of von Willebrand factor is now known to occur in patients with aortic stenosis, and also subaortic obstruction and associated mitral insufficiency in hypertrophic cardiomyopathy, isolated mitral and aortic insufficiency, endocarditis, and in patients with prosthetic valve dysfunction, either from stenosis or insufficiency.
