Background Aortic valve calcium score (AVCS) is a marker for aortic stenosis (AS) severity. We sought to evaluate the effect of aortic valve (AV) variables of flow defined by stroke volume index (SVI), area (AVA), and gradient (MG) on AVCS and study the role of AVCS/MG ratio in patients with low gradient AS.

Methods We retrospectively studied patients undergoing transcatheter aortic valve replacement (TAVR) for severe AS (defined by Echo, Cath, and multimodality team consensus) at our institution from January 1, 2014 through September 1, 2018. AVCS was compared among patient groups defined by their MG (low < or high ≥40 mmHg), echocardiographic SVI (low < or normal ≥35 mL/m2), and AVA (< 0.8 or ≥0.8 cm2) using a three-way factorial ANOVA. The AVCS/MG ratio was developed and compared to AVCS and AVCS/cm2 (annular area) to identify severe AS in patients with low gradient. AVCS/MG was developed based on AVSC (AU) 2000 in males, and 1600 in females/ 40 mmHg (50 and 30, retrospectively)

A265 Lymphocytic Esophagitis: A Single Tertiary Center’S Experience With This Emerging Clinical Entity., C Shams, M Co, M Cappell

Conference Presentation Abstracts

Background: Various disorders can produce esophagitis. Lymphocytic esophagitis (LE) has emerged as another clinical entity responsible for esophagitis symptoms. Although increasingly reported pathologically, the clinical characteristics of LE have not been well characterized. Aims: The present study extends the clinicopathologic characterization of LE by comprehensive analysis of 30 affected patients and identifies specific clinical presentations significantly associated with LE. Methods: Thirty patients were identified from January 2000-December 2016 that satisfied diagnostic criteria for LE by lower esophageal biopsy; (1) high concentration of intraepithelial lymphocytes and (2) few granulocytes (ratio of lymphocytes:granulocytes >50:1). Controls, selected from patients undergoing esophagogastroduodenoscopy (EGD) during …
