The evolving epidemiology of valvular aortic stenosis. The Tromsø Study
TL;DR: This is the first study to document the incidence and prognosis of AS in a general population with surgery as a treatment option, and reveals an accelerated progression of the aortic mean gradient as the disease advances.

Transesophageal and transthoracic echocardiography and Doppler-examinations in systemic lupus erythematosus.
TL;DR: Valve masses and valve thickening are the most frequent structural findings in SLE, occurring more often on the aortic than on the mitral valves, and factors other than antiphospholipid antibodies, medication, hypertension, or coronary heart disease seem to be responsible.

Assessment of risk factors for developing incident aortic stenosis: the Tromsø Study
Gry Wisthus Eveborn,Henrik Schirmer,Per Lunde,Geir Heggelund,John-Bjarne Hansen,Knut Rasmussen +5 more
TL;DR: The data indicate that calcific aortic valve disease is a distinct pathophysiological process, with age, smoking and “wear and tear” of the valve being major contributors to the disease development.

TL;DR: In this paper, a transducer arrangement in cooperation with the conduit provides at least one second path for ultrasonic propagation along the wall via Lamb waves coupling to at least a portion of the flow from a first of the at least two transducers, to a second of said transducers to generate a second received signal.

TL;DR: In this paper, a simulation model which describes the signal transmission for a single acoustic beam in an ultrasonic transit-time flowmeter is described, and some of the capabilities of the model in predicting several important effects in the functioning of a flowmeter signal transmission channel are demonstrated for a given simplified set of design parameters.
