Although patients with atrioventricular (AV) discordance (corrected transposition) have abnormal conduction pathways and may spontaneously develop high-grade AV block, no quantitative assessment of the risk of this happening is available. We reviewed the data on 107 patients with AV discordance ages 2-76 years (mean 22 years) at follow-up. Eighty-two patients (77%) had a ventricular septal defe...

OBJECTIVES Aortic valve (AV) calcification occurs via a pathophysiological process that includes lipoprotein deposition, inflammation, and osteoblastic differentiation of valvular interstitial cells. Here, we investigated the association between endoplasmic reticulum (ER) stress and AV calcification. APPROACH AND RESULTS We identified ER stress activation in AV of patients with calcified AV s...

In a group of 288 patients with acute inferior (diaphragmatic) myocardial infarction, second and third degree atrioventricular (AV) block was diagnosed in 37 (14%). Three of the 37 died. The AV block in the 34 survivors could be differentiated into two distinct types, namely, early and late AV block. In 15 patients, second and third degree AV block developed within 6 hours of the first signs of...

BACKGROUND It is essential to determine the specificity of AV-1451 PET for tau in brain imaging by using pathological comparisons. We performed autoradiography in autopsy-confirmed Alzheimer disease and other neurodegenerative disorders to evaluate the specificity of AV-1451 binding for tau aggregates. METHODS Tissue samples were selected that had a variety of dementia-related neuropathologie...

The many aspects of audiovisual (AV) speech processing have attracted a loyal following from a wide range of perspectives and disciplines. Beginning with the landmark NATO workshop in 1995 [50], a series of international special sessions and meetings has fostered the development of numerous lines of AV speech research. This paper is an introduction to the special session and an inventory of sev...

OBJECTIVE We consider the short- and long-term outcomes of the repair of the isolated partial atrioventricular (AV) septal defect to determine the role played by the atypical forms on the initial AV valve replacement and on the risk of reoperation. METHODS Two hundred and eight patients underwent an operation for this malformation between 1974 and 2001. Clinical and echocardiographic examinat...
