Ultra low-dose of gadobenate dimeglumine for late gadolinium enhancement (LGE) imaging in acute myocardial infarction: a feasibility study.

Purpose: To assess the feasibility of using an ultra-low dose (0.05 mmol/kg of body weight [BW]) of high relaxivity contrast agent for late gadolinium enhancement (LGE) imaging in patients with acute myocardial infarction (AMI).

Materials And Methods: 17 consecutive patients (mean age, 60.

A giant right coronary artery related to a small fistula to the coronary sinus.

Coronary artery fistulas to the coronary sinus are very rare coronary anomalies most often resulting in extreme dilatation of the donor coronary artery and the receiving vessel. However, despite common impressive appearance, their clinical and functional impact may be extremely various from asymptomatic and benign cases to disabling and life threatening situations. To adequately stratify the inherent risks and to plan the most appropriate therapeutic strategy, an overall investigation is necessary.

Automated 3D analysis of multislice computed tomography to define the line of perpendicularity of the aortic annulus and of the implanted valve: benefit on planning transcatheter aortic valve replacement.

Aims: We aimed to determine whether preprocedural analysis of multislice computed tomography (MDCT) scan could accurately predict the "line of perpendicularity" (LP) of the aortic annulus and corresponding C-arm angulations required for prosthesis delivery.

Methods And Results: A 3D analysis of preprocedural MDCT dedicated to define the LP of the aortic annulus was performed in 60 consecutive patients referred for transcatheter aortic valve replacement (TAVR). In 24 patients, the analysis was performed retrospectively to evaluate reproducibility.

Automated 3D analysis of pre-procedural MDCT to predict annulus plane angulation and C-arm positioning: benefit on procedural outcome in patients referred for TAVR.

Objectives: The aim of this study was to determine whether pre-procedural analysis of multidetector row computed tomography (MDCT) scans could accurately predict the "line of perpendicularity" (LP) of the aortic annulus and corresponding C-arm angulations required for prosthesis delivery and impact the outcome of the procedure.

Background: Optimal positioning of the transcatheter aortic prosthesis is paramount to transcatheter aortic valve replacement (TAVR) procedural success.

Methods: All patients referred for TAVR at our center underwent a routine pre-procedural MDCT scan.

Adolescent Kawasaki disease: usefulness of 64-slice CT coronary angiography for follow-up investigation.

Background: Kawasaki disease (KD) is a systemic vasculitis that mainly affects coronary arteries in children, and requires regular follow-up from the time of diagnosis.

Objective: To evaluate the feasibility of 64-slice CT angiography (CTA) for follow-up of patients with KD using previously performed invasive catheter coronary angiography (CCA) as reference standard.

Materials And Methods: The study group comprised 12 patients (age 17.

Non-invasive evaluation of coronary artery stent patency with retrospectively ECG-gated 64-slice CT angiography.

The aim of our study has been to evaluate the ability of 64-slice computed tomographic angiography (CTA) to assess coronary artery stent patency, relative to selective coronary angiography (SCA). Fifty-five consecutive patients (age range 45-80 years) with 97 previously implanted coronary artery stents underwent 64-slice CTA. The 55 patients comprised 40 subjects (group A) who were referred for follow-up SCA at a mean interval of 9.
