Abstract

Up to 40% of patients with aortic stenosis (AS) present with a "discordant grading" usually referred to as "low-gradient AS." This article presents a step-by-step integrative approach overview of the utility, limitations, and complementary role of the different imaging modalities for the assessment of AS severity with a special emphasis on the reconciliation of discordant grading. The first step is to confirm the validity of echocardiographic measures of AS severity. For example, hybrid imaging can combine left ventricular outflow tract area measured by 3-dimensional echocardiography or contrast enhanced multidetector row computed tomography with flow velocities measured by Doppler. The next step is to differentiate severe from non-severe AS with the use of low-dose dobutamine stress echocardiography, especially in patients with low left ventricular ejection fraction, low-flow, low-gradient AS. Aortic valve calcium scoring measured by noncontrast multidetector row computed tomography is preferred in patients with low-gradient AS and preserved left ventricular ejection fraction as well as in those with inconclusive results with dobutamine stress echocardiography.

Abstract

BACKGROUND: Scientific guidelines consider atrial fibrillation (AF) complicating degenerative mitral regurgitation (DMR) a debated indication for surgery. OBJECTIVES: This study analyzed the prognostic/therapeutic implications of AF at DMR diagnosis and long-term. METHODS: Patients were enrolled in the MIDA (Mitral Regurgitation International Database) registry, which reported the consecutive, multicenter, international experience with DMR due to flail leaflets echocardiographically diagnosed. RESULTS: Among 2,425 patients (age 67 ± 13 years; 71% male, 67% asymptomatic, ejection fraction 64 ± 10%), 1,646 presented at diagnosis with sinus rhythm (SR), 317 with paroxysmal AD, and 462 with persistent AF. Underlying clinical/instrumental characteristics progressively worsened from SR to paroxysmal to persistent AF. During follow-up, paroxysmal and persistent AF were associated with excess mortality (10-year survival in SR and in paroxysmal and persistent AF was 74 ± 1%, 59 ± 3%, and 46 ± 2%, respectively; p < 0.0001), that persisted 20 years post-diagnosis and independently of all baseline characteristics (p values
