[Conservative treatment of a pseudoaneurysm of the mitral-aortic intervalvular fibrosa: 9 years of follow-up].

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (MAIVF-P) is one of the rare complications of endocarditis or, more rarely, of surgical trauma. This condition is characterized by a pseudoaneurysm in the intra-annular area between the mitral valve and the aortic valve communicating with the outflow tract of the left ventricle, between the coronary or noncoronary left aortic valve and the front flap of the mitral valve. Nowadays, surgery is recommended to avoid further growth and complications.

Prosthesis depth and conduction disturbances after last generation balloon-expandable transcatheter aortic valve implantation.

Aims: Preliminary data on Sapien 3 valve (S3-THV) use for transcatheter aortic valve implantation have shown an increased permanent pacemaker implantation (PPMI) rate with respect to Sapien XT valve. Aim of this study was to investigate the role of S3-THV position in the left ventricular outflow tract (LVOT) on electrocardiographic changes suggestive of atrioventricular (ΔPR) and/or intraventricular (ΔQRS) conduction abnormalities and 30 days PPMI rate.

Methods And Results: Eighty-six consecutive patients treated with S3-THV were included in the study.
