Prevalence of aortic valve stenosis in patients affected by gastrointestinal angiodysplasia.
OBJECTIVE
Angiodysplasia is considered to be an important cause of gastrointestinal bleeding in the elderly. An association between idiopathic gastrointestinal bleeding and aortic valve stenosis has been reported in up to 25% of the patients. The association between angiodysplasia mainly of the right colon and aortic valve stenosis has been suggested, but is not proven. The aim of this study was to examine the prevalence of aortic valve stenosis in patients with gastrointestinal angiodysplasia.


METHODS
We studied retrospectively 83 patients submitted to gastrointestinal endoscopy and found affected by angiodysplasia. Of them 24 (16M and 8F) had died from causes unrelated to cardiovascular diseases. The 59 patients still alive (27M and 32F) underwent a complete clinical, electrocardiographic and echocardiographic (M-mode, B-mode, pulsed and continuous-wave Doppler) evaluation.


RESULTS
Fifteen patients (25%) had a normal examination, both clinical and echocardiographic. Eleven (19%) had minor cardiac abnormalities but had no murmurs. Although no murmurs were present in 15 patients (25%), some echocardiographic abnormalities such as aortic leaflet sclerosis, mitral annular calcification, their association, or trivial mitral regurgitation detectable only at PW-Doppler were found. In 18 patients (31%) both systolic murmurs and valvular abnormalities, as revealed by echocardiographic examination, were detected: 10 had a regurgitant and 8 an ejectional murmur; of these only 1 (1.6%) had a true severe calcified aortic valve stenosis at echo-Doppler examination.


CONCLUSIONS
The low prevalence of aortic valve stenosis in patients with gastrointestinal angiodysplasia (1/59 or 1.6%) in this retrospective study argues against the association of gastrointestinal angiodysplasia and aortic valve stenosis.
