Trunk Muscle Cross-Sectional Area as a Predictive Factor for Length of Postoperative Hospitalization after Surgical Aortic Valve Replacement.

Trunk Muscle Cross-Sectional Area as a Predictive Factor for Length of Postoperative Hospitalization after Surgical Aortic Valve Replacement. Ann Thorac Cardiovasc Surg. 2020 Jan 29;: Authors: Taniguchi N, Hosono M, Kuwauchi S, Yasumoto H, Kawazoe K Abstract PURPOSE: We investigated the utility of trunk muscle cross-sectional area to predict length of hospitalization after surgical aortic valve replacement (AVR) for aortic stenosis (AS). METHODS: Adult AS patients who underwent isolated AVR at a single institution were studied. The cross-sectional area of the erector spinae muscles (ESM) at the first and second lumbar vertebrae and that of the psoas muscle (PM) at the third and fourth lumbar vertebrae were measured on preoperative computed tomography (CT). Each was indexed to body surface area. Risk factors for prolonged postoperative hospitalization (>3 weeks) were assessed using multivariate regression analyses. RESULTS: Of 56 patients (mean age 76 ± 9 years; 25 men), 20 (35.7%) patients required prolonged hospitalization. A smaller indexed ESM cross-sectional area at the first lumbar vertebra (per 1 cm/m2, odds ratio [OR] = 0.71, 95% confidence interval [CI] = 0.57-0.88, P

Authors: Ma J, Wang L, Chen R, Yan J, Liang Y, Liu P Abstract A 77-year-old woman with extremely high risk of mortality due to severe aortic stenosis (AS) and multiple organ failure was admitted to the affiliated hospital of Jiangsu University. She did not receive regular treatment since being diagnosed with AS 17 months previously. Frequent breakout of acute left heart failure after admission, with a low ostium of the left coronary artery showed by computed tomography, the patient underwent transcatheter aortic valve replacement (TAVR). Though cardiac conduction system abnormalities and a short-term elevation of p...

This article summarizes current guidelines and best practices for the management of low-flow, low-gradient aortic stenosis. Summary Low-flow, low-gradient aortic stenosis is a difficult entity to diagnose and treat. Various diagnostic modalities are needed to accurately determine the severity of aortic stenosis and potential treatment benefit. True-severe classical and paradoxical low-flow, low-gradient aortic stenosis can be distinguished from pseudo-severe aortic stenosis by dobutamine stress echocardiography and/or multidetector computed tomography. Once the distinction is made, aortic valve replacement results in be...

We present extensive in vitro durability and stability testing of a novel polymeric TAVR valve (PolyNova valve) using 1) accelerated wear testing (AWT, ISO 5840); 2) calcification susceptibility (in the AWT)—compared with clinically used tissue valves; and 3) extended crimping stability (valves crimped to 16 Fr for 8 days). Hydrodynamic testing was performed every 50M cycles. The valves were also evaluated visually for structural integrity and by scanning electron microscopy for evaluation of surface damage in the micro-scale. Calcium and phosphorus deposition was evaluated using micro-computed tomography (μCT) an...

This study sought to derive and validate a systematic method enabling AVC quantification using computed tomography angiography (CTA) in patients with AS.Methods134 consecutive patients with AS who underwent both NCCT and CTA were included in the study and sub-divided into derivation (n=71) and validation cohorts (n=63). On NCCT, AVC was quantified using Agatston method utilizing the software developed for semi-automatic assessment of coronary calcium. On CTA, mean contrast attenuation of aorta (AortaHU) and standard deviation (SD) was measured in the region-of-interest at level of sinotubular junction.ResultsUsing an adjus...

AbstractAortic valvular calcium score (AVCS) can identify severe aortic stenosis (AS) and provide powerful prognostic information. In severe and symptomatic AS, patients can be referred for a transcatheter aortic valve replacement (TAVR). The aim of this study was to determine whether AVCS, measured on the preoperative contrast enhanced multislice computed tomography (MSCT), is associated with device success (DS), major adverse cardiac events (MACEs) and paravalvular leak (PVL) after TAVR. Three hundred and fifty-two consecutive patients who underwent TAVR with a preoperative standardised contrast enhanced MSCT were includ...

Computed tomography angiography derived global longitudinal strain (CTA-GLS) has been shown to be feasible, however its prognostic value remains unclear in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). We evaluated the association of baseline CTA-GLS with outcomes including all-cause mortality and composite endpoint of death and heart failure hospitalization in 223 patients treated with TAVR. Patients with normal LVEF but reduced CTA-GLS had similar event rate to those with impaired LVEF, and higher than those with normal LVEF and preserved CTA-GLS. Baseline CTA-GLS assessme...

AbstractAortic stenosis (AS) represents a major healthcare issue because of its ever-increasing prevalence, poor prognosis, and complex pathophysiology. Echocardiography plays a central role in providing a comprehensive morphological and hemodynamic evaluation of AS. The diagnosis of severe AS is currently based on three hemodynamic parameters including maximal jet velocity, mean pressure gradient (mPG) across the aortic valve, and aortic valve area (AVA). However, inconsistent grading of AS severity is common when the AVA is
