Coronary Artery Disease Assessed by Computed Tomography-Based Leaman Score in Patients With Low-Risk Transcatheter Aortic Valve Implantation

We aimed to evaluate the burden of coronary artery disease (CAD) using the computed tomography (CT) Leaman score in low-risk transcatheter aortic valve implantation (TAVI) patients. The extent of CAD in low-risk patients with aortic stenosis who are candidates for TAVI has not been accurately quantified. The CT Leaman score was developed to quantify coronary CT angiography (CCTA) atherosclerotic burden and has been validated to evaluate the extent of CAD. CT Leaman score>5 has been associated with an increase in major adverse cardiac events over long-term follow-up.

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...

A previously asymptomatic fifty year old male presented with shortness of breath and chest pain for past 6 months. He underwent a transthoracic echocardiography which showed presence of a bicuspid aortic valve with severe stenosis. He further underwent CT angiography for evaluation of coronary arteries and aortic root dimensions. Review of CTA images incidentally revealed an anomalous origin of left circumflex artery (LCx) from the right pulmonary artery (RPA) (Figure 1A-B). The left anterior descending artery (LAD) and the right coronary artery (RCA) were dilated and extremely tortuous with extensive collateralization to ...

A 9-year-old-boy with characteristic facies (broad forehead, periorbital fullness, upturned nose, long philtrum, full lips, small chin, and prominent cheeks) (Figure 1) and presenting with progressive dyspnea and mental retardation underwent transthoracic echocardiography, which revealed supravalvular aortic stenosis (SVAS). For further evaluation, he was referred for computed tomography angiography (CTA) which demonstrated diffuse, long-segment stenosis of the ascending aorta along with significant ostioproximal stenosis of the right brachiocephalic artery and left common carotid artery with diffuse dilatation of the post...

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...
