Comparative StudyRotational angiography for preinterventional imaging in transcatheter aortic valve implantation.
To evaluate the clinical value of 3D rotational angiography, as a tool for imaging and measuring 3D anatomy, coupled with transesophageal echocardiogram (TEE) as preinterventional imaging for transcatheter aortic valve implantation (TAVI) procedures. ⋯ Given that this technology is available in the cathlab at reasonable dose levels, 3D rotational angiography has proven to be a suitable preinterventional 3D imaging modality for TAVI procedures. Together, the raw angiographic data and the reconstructed 3D volume provide all the necessary anatomical information necessary for this procedure, including the measurements.

Comparative StudyClinical outcome following Transcatheter Aortic Valve Implantation in patients with impaired left ventricular systolic function.
To determine the prevalence of impaired left ventricular (LV) systolic function and its impact on the in-hospital and long-term outcome in patients who underwent Transcatheter Aortic Valve Implantation (TAVI). ⋯ The immediate and long-term outcome after TAVI did not differ between patients with an impaired and preserved LVEF. LVEF ≤ 35% did not predict adverse immediate and long-term outcome. These findings suggest that TAVI should not be withheld in selected patients with impaired LV function.

Comparative StudyTransaortic Transcatheter Aortic valve implantation using Edwards Sapien valve: a novel approach.
To evaluate feasibility and outcome of Transoartic Transcatheter Sapien valve implantation. ⋯ The TA-TAVI approach may not be desirable in patients with severe chest deformity, poor lung function or poor left ventricular function. TAo-TAVI via a partial sternotomy is safe and feasible in these patients.

Comparative StudyTransapical treatment of paravalvular leaks in patients with a logistic EuroSCORE of more than 15%: acute and 3-month outcomes of a "proof of concept" study.
We describe the short-term results of the patients who underwent transapical treatment of a paravalvular leak (PVL) in our centre. ⋯ Transapical paravalvular leak reduction might be a good or rather attractive alternative in high-risk patients for major re-do cardiac surgery.
