Prosthesis-patient mismatch is an independent predictor of congestive heart failure after transcatheter aortic valve replacement.

Background: Little is known about the effect of prosthesis-patient mismatch (PPM) on outcomes after transcatheter aortic valve replacement. We reported previously an increased risk of PPM with the SAPIEN 3 transcatheter heart valve (S3-THV).

Aims: To investigate the association of PPM with 1-year outcomes in patients with severe aortic stenosis (AS) implanted with S3-THV.

Left-ventricular non-compaction-comparison between different techniques of quantification of trabeculations: Should the diagnostic thresholds be modified?

Background: Diagnosis of left ventricular non-compaction (LVNC) is challenging, and different imaging techniques propose different criteria.

Aim: To compare the value of two-dimensional transthoracic echocardiography (2D-TTE) and cardiac magnetic resonance (CMR) criteria in diagnosing LVNC, and to test a new trabecular quantification method obtained by 2D-TTE, exploring its relationship with CMR non-compacted mass quantification.

Methods: From a multicentre French study, we selected 48 patients with LVNC and 20 with dilated cardiomyopathy (DCM) who underwent 2D-TTE and CMR.
