A 71-year-old Jehovah ’s witness woman with a past medical history significant for diabetes mellitus, hypertension, breast cancer, aortic stenosis, and coronary artery disease underwent three-vessel coronary artery bypass graft (CABG) and surgical aortic valve replacement (SAVR) with a 19 mm Sorin Mitroflow (Sorin Grou p, CO, USA) (True internal diameter 15.4 mm). Severe patient prosthesis mismatch (PPM) (EOAi: 0.30 cm2/m2) was diagnosed shortly after surgery with post-operative mean gradients of 40 mmHg by echocardiography.

Purpose: Identify a measurable parameter from test bolus of computed tomography angiography that can differentiate aortic stenosis patients with normal systolic function from those with heart failure and reduced ejection fraction (HFrEF). Materials and Methods: This retrospective study included patients (undergoing evaluation for transcatheter aortic valve replacement) who had retrospective electrocardiogram-gated cardiac computed tomography angiography using test bolus. The measured variables were time to peak contrast enhancement in the pulmonary artery (PAtime), in the ascending (AsAotime) and descending aorta (DsA...

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...

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]

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.
