However, a systolic-only disjunction is merely apparent, and 2 distinct phenotypes have been identified: True-MAD (atrial displacement of the posterior leaflet in diastole and systole) and Pseudo-MAD (apparent displacement in systole only). The prevalence of True-MAD and Pseudo-MAD in mitral valve prolapse (MVP) is not known. The aim of this study was to assess the prevalence of True-MAD and Pseudo-MAD in myxomatous MVP patients by transthoracic echocardiography (TTE) and to validate TTE compared to cardiac magnetic resonance (CMR; reference standards).</div></div><div><h3>Methods</h3><div>Consecutive patients who underwent TTE for MVP were included. Mitral annular phenotype was evaluated in the TTE parasternal long-axis view. Accuracy (against CMR) and intra-/interrater reliability of TTE were also assessed.</div></div><div><h3>Results</h3><div>Six hundred three consecutive patients were included. The prevalence of True-MAD and Pseudo-MAD was 7% (42) and 37% (221) (<em>P</em> &lt; .05), respectively. Accordingly, 221 of 263 (84%) patients classically classified as “MAD” would have been reclassified as Pseudo-MAD. Pseudo-MAD prevalence and systolic length increased with higher mitral regurgitation (MR) severity (23% for mild MR, 36% for moderate MR, 44% for severe MR [<em>P</em> &lt; .05]; 6 ± 2 mm for mild MR; 8 ± 2 mm for moderate MR; 10 ± 2 mm for severe MR [<em>P</em> &lt; .05]), while True-MAD prevalence was consistent across MR grades. Pseudo-MAD was linked to systolic curling and Pickelhaube. Transthoracic echocardiography showed an overall accuracy of 0.89 (Cohen <em>k</em> 0.80), a substantial interrater agreement of 0.87 (<em>k</em> = 0.76), and an almost perfect intrarater agreement of 0.93 (<em>k</em> = 0.85).</div></div><div><h3>Conclusions</h3><div>True-MAD, unlike Pseudo-MAD, is rare in patients with MVP. Pseudo-MAD is associated with the grade of MR and other echocardiographic features of advanced myxomatous degeneration.

Approximately 50% of patients with heart failure have heart failure with preserved ejection fraction (HFpEF) and concomitant diastolic dysfunction (DD), in part caused by increased myocardial stiffness not detectable by standard echocardiography. While elastography can map tissue stiffness, cardiac applications are currently limited, especially in patients with a higher body mass index. Therefore, we developed cardiac time-harmonic elastography (THE) to detect abnormal diastolic myocardial stiffness associated with DD.</p><p><strong>Material and methods: </strong>Cardiac THE was developed using standard medical ultrasound and continuous external vibration for regionally resolved mapping of diastolic shear wave speed as a proxy for myocardial stiffness. The method was prospectively applied to 54 healthy controls (26 women), 10 patients with moderate left ventricular hypertrophy (mLVH; 5 women), and 45 patients with wild-type transthyretin amyloidosis (wTTR; 4 women), 20 of whom were treated with tafamidis.

Area under the curve values were 0.991 and 0.737 for discriminating wTTR and mLVH from healthy controls, respectively. Shear wave speed was reduced in patients after tafamidis treatment (2.6 ± 0.6 m/sec, P = .04), suggesting the potential value of THE for therapy monitoring.
