Ten years' experience with the sutureless aortic valve replacement: incidence and predictors for survival and valve durability at follow-up.

Objectives: Aortic valve replacement with a sutureless prosthesis [sutureless aortic valve replacement (Su-AVR)] is an option for patients with severe aortic valve stenosis. However, data regarding long-term outcomes and prosthesis durability are still lacking.

Methods: All consecutive patients who successfully underwent Su-AVR with the Perceval valve in our centre between 2010 and 2020 were included in the analysis and followed prospectively with echocardiography.

Risk of conduction disturbances following different transcatheter aortic valve prostheses: the role of aortic valve calcifications.

Objectives: To assess the impact of prosthesis choice and aortic valve calcifications on the occurrence of conduction disturbances after transcatheter aortic valve implantation (TAVI).

Methods: We retrospectively analyzed the preoperative clinical characteristics, electrocardiograms, contrast-enhanced multidetector computed tomography scans and procedural strategies of patients who underwent TAVI in our center between January 2012 and June 2017. Quantification of calcium volume was performed for each aortic cusp above (aortic valve) and below (left ventricular outflow tract, LVOT) the basal plane.

Redo aortic valve replacement for prosthesis endocarditis in patients previously classified as high or prohibitive risk: a narrative review.

Transcatheter aortic valve implantation (TAVI) and sutureless aortic valve replacement (Su-AVR) enabled in the last years many patients at high or prohibitive risk to be treated for their severe symptomatic aortic valve stenosis. As often happens in medicine, new techniques bring not only new hopes, but also new problems. In recent years, alongside the lengthening of the life of these patients treated with TAVI or Su-AVR, cardiologists and cardiac surgeons have had to face the long-term complications associated with the implantation of these devices, such as the prosthetic infective endocarditis.

Risk factors for atrioventricular block after transcatheter aortic valve implantation: a single-centre analysis including assessment of aortic calcifications and follow-up.

Aims: To assess the contribution of aortic valve calcification to the occurrence of transient or permanent atrioventricular block (AVB) and the need for permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) in a large single-centre cohort.

Methods And Results: We retrospectively analysed pre-operative contrast-enhanced multidetector computed tomography scans of patients who underwent TAVI in our centre between 2012 and 2016. Calcium volume was calculated for each aortic cusp above (aortic valve), and below [left ventricular outflow tract (LVOT)] the basal plane.

The Perceval S aortic valve has the potential of shortening surgical time: does it also result in improved outcome?

Background: Sutureless aortic valve prostheses have the potential of shortening surgical time. However, whether shorter operative times may also result in improved patient outcomes remains to be established.

Methods: One hundred patients underwent minimally invasive isolated aortic valve replacement.
