The most widespread acquisition protocol consisted of an ECG-gated CT angiography (CTA) scan of the aortic root and heart followed by a non-ECG-synchronized CTA of the thorax, abdomen, and pelvis. Contrast agent administration was generally tailored on the patient's body weight with a ...
TCT-847 Adequate choice of the post dilatation balloon size in patients undergoing TAVI based on the CT scan analysisBackground: To our knowledge no data exists comparing new generation commercially available devices for transfemoral (TF) transcatheter aortic valve implantation (TAVI). Methods: All ...
For SLCT, spiral CTA with retrospective ECG-gating was performed to capture the heart and the access route simultaneously in one scan. Objective image quality was compared at different levels of the arterial access route. Results40keV virtual monoenergetic images of DLCT showed a significantly ...

Serum creatinine and the eGFR were recorded pre-TAVI CT scan and after the procedures as reference of CM to renal function. RESULTS. CTA was successfully performed in all patients. Mean creatinine was 2.25 ± 0,76 mg/dL and mean GFR was 26.5± 8.1 mL/min/m2. Mean vessel attenuation was...
We sought to evaluate the impact of annulus measurement by transthoracic echocardiography (TTE) and by CT scan on the occurrence of AR. Methods The study included 43 symptomatic patients (83 ± 8 years, 72% in NYHA ≥ III) with severe aortic stenosis [0.76 ± 0.19 cm2,...
This prospective single-center study considered 100 consecutive patients clinically referred for pre-TAVI CT. They were examined on a dual-layer detector CT scanner to obtain an ECG-gated cardiac scan and a non-ECG-gated aortoiliofemoral scan. Either a standard contrast medi...

The procedure was performed via transfemoral route using a balloon expandable (n=61) or a self expandable (n=57) valve. Pre-intervention non enhanced, ECG-gated, multislice CT-scan was done in all patients. Aortic valve calcifications were evaluated using the Agatston calcium score (CS). ...
The access was previously guided by the CT scan data: usually, a percutaneous transfemoral approach was preferred but also a ventricular transapical or transaortic approach was performed in case of the calcified or inadequate peripherical vascular route. A temporary ventricular pacemaker allowed an ...
