Abstract Background Clinical significance of concomitant mitral regurgitation (MR) in patients with severe aortic stenosis (AS) has not been well-studied. Purpose The purpose of this study is to investigate the prognostic impact of concomitant MR in patients with severe AS. Method We used the data of 3815 patients from the CURRENT AS registry, a retrospective multicenter registry of severe AS in Japan. We compared the clinical outcomes between patients with moderate/severe MR and with none/mild MR according to the initial treatment strategies (initial aortic valve replacement [AVR] or conservative strategy). The primary outcome measure was a composite of aortic valve-related death and heart failure hospitalisation. Results Among the study population, moderate/severe MR were observed in 227/1197 (19%) patients with initial AVR strategy and in 536/2618 (20%) patients with conservative strategy. Among survivors with the initial AVR strategy, moderate/severe MR improved in 61/62 (98%) patients with concomitant mitral procedures. The crude cumulative 5-year incidence of the primary outcome measure was significantly higher in patients with moderate/severe MR than in those with none/mild MR regardless of the treatment strategies (25.2% vs. 14.4%, P<0.001 in the initial AVR strategy; 63.3% vs 40.7%, P<0.001 in the conservative strategy). Multivariate analysis revealed moderate/severe MR at index echocardiography was independently associated with higher risk for the primary outcome measure in conservative strategy (adjusted HR 1.20, 95% CI 1.03–1.40, P=0.023), but not associated in the initial AVR strategy (adjusted HR 1.20, 95% CI 0.82–1.80, P=0.339). Conclusion Moderate/severe MR was independently associated with poorer outcome in patients with severe AS who were managed conservatively, but not in those with initial AVR strategy.

AbstractWhile the prognostic impact of QRS axis deviation has been assessed, it has never been investigated in patients without conduction block. Thus, we evaluated the prognostic impact of QRS-axis deviation in patients without conduction block. We retrospectively analyzed 3353 patients who had undergone both scheduled transthoracic echocardiography and electrocardiography in 2013 in a hospital-based population, after excluding patients with a QRS duration of ≥ 110 ms, pacemaker placement, and an QRS-axis − 90° to − 180° (northwest axis). The study population was categorized into three groups depending on the mean frontal plane QRS axis as follows: patients with left axis deviation (N = 171), those with right axis deviation (N = 94), and those with normal axis (N = 3088). The primary outcome was a composite of all-cause death and major adverse cardiovascular events. The cumulative 3-year incidence of the primary outcome measure was significantly higher in the left axis deviation group (26.4% in the left axis deviation, 22.7% in the right axis deviation, and 18.4% in the normal axis groups, log-rank P = 0.004). After adjusting for confounders, the excess risk of primary outcome measure remained significant in the left axis deviation group (hazard ratio [HR] 1.44; 95% confidence interval [CI] 1.07–1.95; P = 0.02), while the excess risk of primary outcome measure was not significant in the right axis deviation group (HR 1.22; 95% CI 0.76–1.96; P = 0.41). Left axis deviation was associated with a higher risk of a composite of all-cause death and major adverse cardiovascular events in hospital-based patients without conduction block in Japan.

Abstract Objective The objective of this study was to assess imaging predictors of mitral regurgitation (MR) improvement and to evaluate the impact of MR regression on long-term outcome in patients undergoing transcatheter aortic valve replacement (TAVR). Background Concomitant MR is a frequent finding in patients with severe aortic stenosis but usually left untreated at the time of TAVR. Methods Mitral regurgitation was graded by transthoracic echocardiography before and after TAVR in 677 consecutive patients with severe aortic stenosis. 2-year mortality was related to the degree of baseline and discharge MR. Morphological echo analysis was performed to determine predictors of MR improvement. Results 15.2% of patients presented with baseline MR ≥ 3 +, which was associated with a significantly decreased 2-year survival (57.7% vs. 74.4%, P < 0.001). MR improved in 50% of patients following TAVR, with 44% regressing to MR ≤ 2 +. MR improvement to ≤ 2 + was associated with significantly better survival compared to patients with persistent MR ≥ 3 +. Baseline parameters including non-severe baseline MR, the extent of mitral annular calcification and large annular dimension (≥ 32 mm) predicted the likelihood of an improvement to MR ≤ 2 +. A score based on these parameters selected groups with differing probability of MR ≤ 2 + post TAVR ranging from 10.5 to 94.4% (AUC 0.816; P < 0.001), and was predictive for 2-year mortality. Conclusion Unresolved severe MR is a critical determinant of long term mortality following TAVR. Persistence of severe MR following TAVR can be predicted using selected parameters derived from TTE-imaging. These data call for close follow up and additional mitral valve treatment in this subgroup. Graphic abstract Factors associated with MR persistence or regression after TAVR

Abstract Aims Severe aortic stenosis (AS) and functional mitral regurgitation (MR) frequently coexist. There is no consensus about the optimal therapeutic strategy for patients with combined valve disease. Evidence has shown that double valve surgery is associated with high complication rates and mortality, whereas MR severity may improve after transcatheter aortic valve implantation (TAVI). To date, little is known on prognostic parameters associated with MR improvement after TAVI. Recently, a new echocardiographic parameter based on the ratio between peak E velocity and peak atrial longitudinal strain (E/PALS) has demonstrated to be accurate and sensitive in the prediction of elevated filling pressure. Its role in the setting of AS patients undergoing TAVI has never been investigated. Our study aims to evaluate haemodynamic conditions and left ventricular (LV) systolic and diastolic function in patients with severe AS and concomitant MR undergoing TAVI and to identify new echocardiographic parameters associated with MR improvement 1 month after the aortic valve replacement. Methods We prospectively enrolled 87 consecutive patients (mean age 80 ± 6 years) with severe symptomatic AS and concomitant MR undergoing TAVI between 2016 and 2021, for whom a complete echocardiographic assessment was available at baseline and 1 month after the procedure, selected from the EffecTAVI registry. Exclusion criteria were prior valve surgery, severe mitral stenosis, permanent atrial fibrillation, and poor ultrasound acoustic window. Echo-Doppler assessment, including global longitudinal strain (GLS) and peak atrial longitudinal strain (PALS), was performed before and after 1 month to TAVI procedure. Changes (Δ) of the main echo parameters before and after intervention were computed. Results A month after the procedure, 20 (23%) patients had a reduction of at least one degree of MR (P &lt;0.001). Dividing study population in two groups, based on whether or not MR was reduced after TAVI, we found that patients with MR improvement had higher LV end-diastolic volume (P = 0.036) and left atrial volume (P = 0.015) at baseline compared with those without MR reduction. After TAVI no significant differences were found in heart chambers size between the two groups, but a significant increase in PALS (23.2 ± 7.3 vs. 22.3 ± 7, P=0.028), together with a reduction in E/A ratio (0.69 ± 0.14 vs. 0.90 ± 0.46, P = 0.046) were detected in patients with MR reduction. Furthermore, Δ E/PALS (−17.3±34.4% vs. 3.9±35.0% P=0.027), Δ E/A (−12.6±33.9% vs. 24.7±64.3%, P=0.018) and Δ systolic pulmonary artery pressure (sPAP) (−13.0±20.2% vs. −2.0±18.3, P=0.031) were significantly higher in patients with MR improvement to compared those without MR reduction. By the multivariate logistic regression analysis performed in the pooled population, Δ E/PALS (OR 0.968, 95% CI: 0.947–0.990, P=0.005), together with LV mass at baseline (OR 1.056, 95% CI: 1.007–1.107, P = 0.024) appeared to be independently associated with MR reduction post-TAVI. Conclusions Our study demonstrated that: after TAVI in a significant percentage of patients a relevant improvement in concomitant MR was detected; in the group of patients with improved MR a parallel improvement of sPAP, E/A and E/PALS ratio post TAVI was found; Δ E/PALS appears to be the main parameter independently associated with the reduction of MR severity.
