Aortic annulus measurement with computed tomography angiography reduces aortic regurgitation after transfemoral aortic valve replacement compared to 3-D echocardiography: a single-centre experience.

CONCLUSION: MDCT is superior to 3-D TEE in terms of sizing accuracy and clinical outcomes. Reduction of PVR after TAVR with MDCT is likely due to valve annulus undersizing by TEE. PMID: 30972479 [PubMed - as supplied by publisher]

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...

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...

A 81-year-old male patient with chronic obstructive lung disease, decompensated severe calcified aortic stenosis, moderately to severely reduced biventricular systolic function, and atrial fibrillation with secondary pulmonary hypertension was referred to our institution. He was treated with diuretics, oral anticoagulants followed by low dose beta blocker. After cardiac recompensation coronary artery disease was excluded by coronary angiogram. Computed tomography (CT) angiography was performed prior to transcatheter aortic valve replacement (TAVR). Unexpectedly, CT (Panel C) and transthoracic echocardiography without contr...

Global longitudinal strain (GLS) detects subclinical myocardial changes in patients with aortic stenosis (AS). Although GLS is typically measured by transthoracic echocardiography (TTE), assessment by multiphasic gated computed tomography angiography (CTA) has become recently available. We sought to evaluate the feasibility of CTA-derived GLS assessment and compare its agreement with TTE using the same post-processing software in severe AS patients undergoing transcatheter aortic valve replacement (TAVR) evaluation.

In conclusion, on the basis of a significance cut-off value of 50% diameter stenosis, CTCA provides acceptable diagnostic accuracy for the exclusion of coronary artery disease in patients referred for TAVI. Using the routinely performed preoperative computed tomography scans as a gatekeeper for coronary angiography could decrease additional coronary angiographies by 37% in this high-risk and fragile population.

Authors: Hourai R, Kasashima S, Fujita SI, Sohmiya K, Daimon M, Hirose Y, Katsumata T, Kanki S, Ozeki M, Ishizaka N Abstract A 74-year-old man was admitted for preoperative screening of aortic stenosis. Five months before this admission, he was found to have elevated serum immunoglobulin G4 (IgG4; 2,010 mg/dL). Computed tomography (CT) showed a soft tissue mass surrounding the abdominal aorta, suggestive of IgG4-related periaortitis. CT coronary angiography showed perivascular thickening of the right coronary artery, and subsequent coronary angiography showed a multi-vessel disease. The patient underwent aortic val...
