<b><i>Background:</i></b> The use of rapid deployment and sutureless aortic prostheses is increasing. Previous reports have shown promising results on haemodynamic performance and mortality rates. However, the impact of these bioprostheses on left ventricular mass (LVM) regression remains unknown. We decided to study the changes in remodelling and LVM regression in isolated severe aortic stenosis treated with conventional or Perceval® or Intuity® valves. <b><i>Method and Results:</i></b> From January 2011 to January 2016, 324 bioprostheses were implanted in our centre. The collected characteristics were divided into 3 groups: conventional valves, Perceval®, and Intuity®, and they were analysed after 12 months. There were 183 conventional valves (56%), 72 Perceval® (22%), and 69 Intuity® (21.2%). The statistical analysis showed significant differences in transprosthetic postoperative peak gradient (23 [18–29] mm Hg vs. 21 [16–29] mm Hg and 18 [14–24] mm Hg, <i>p</i> &#x3c; 0.001), ventricular mass electrical criteria regression (Sokolow and Cornell products), and 1-year survival (90 vs. 93% and 97%, log rank <i>p</i> value = 0.04) in conventional, Perceval®, and Intuity® groups. <b><i>Conclusions:</i></b> We observed differences in haemodynamic, electrocardiographic, and echocardiographic parameters related to the different types of prosthesis. Patients with the Intuity® prosthesis had the highest reduction in peak aortic gradient and the higher ventricular mass regression. Besides, patients with the Intuity® prosthesis had less risk of mortality during follow-up than the other two groups. Further studies are needed to confirm these findings.

The Impact

AimsThere is an increasing awareness of gender-related differences in patients with severe aortic stenosis and their outcomes after surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI).MethodsData from the IMPULSE registry were analysed. Patients with severe aortic stenosis (AS) were enrolled between March 2015 and April 2017 and stratified by gender. A subgroup analysis was performed to assess the impact of age.ResultsOverall, 2171 patients were enrolled, and 48.0% were female. Women were characterised by a higher rate of renal impairment (31.7 vs 23.3%; p<0.001), were at higher surgical risk (EuroSCORE II: 4.5 vs 3.6%; p=0.001) and more often in a critical preoperative state (7.0vs 4.2%; p=0.003). Men had an increased rate of previous cardiac surgery (9.4 vs 4.7%; p<0.001) and a reduced left ventricular ejection fraction (4.9 vs 1.3%; p<0.001). Concomitant mitral and tricuspid valve disease was substantially more common among women. Symptoms were highly prevalent in both women and men (83.6 vs 77.3%; p<0.001). AVR was planned in 1379 cases. Women were more frequently scheduled to undergo TAVI (49.3 vs 41.0%; p<0.001) and less frequently for SAVR (20.3 vs 27.5%; p<0.001).ConclusionsThe present data show that female patients with severe AS have a distinct patient profile and are managed in a different way to males. Gender-based differences in the management of patients with severe AS need to be taken into account more systematically to improve outcomes, especially for women.

Natural Progression

Because the natural progression of low-gradient aortic stenosis (LGAS) has not been well defined, we performed a retrospective study of 116 consecutive patients with aortic stenosis who had undergone follow-up echocardiography at a median interval of 698 days (range, 371–1,020 d). All patients had preserved left ventricular ejection fraction (&gt;0.50) during and after follow-up. At baseline, patients were classified by aortic valve area (AVA) as having mild stenosis (≥1.5 cm2), moderate stenosis (≥1 to &lt;1.5 cm2), or severe stenosis (&lt;1 cm2). Severe aortic stenosis was further classified by mean gradient (LGAS, mean &lt;40 mmHg; high-gradient aortic stenosis [HGAS], mean ≥40 mmHg). We compared baseline and follow-up values among 4 groups: patients with mild stenosis, moderate stenosis, LGAS, and HGAS. At baseline, 30 patients had mild stenosis, 54 had moderate stenosis, 24 had LGAS, and 8 had HGAS. Compared with the moderate group, the LGAS group had lower AVA but similar mean gradient. Yet the actuarial curves for progressing to HGAS were significantly different: 25% of patients in LGAS reached HGAS status significantly earlier than did 25% of patients in the moderate-AS group (713 vs 881 d; P=0.035). Because LGAS has a high propensity to progress to HGAS, we propose that low-gradient aortic stenosis patients be closely monitored as a distinct subgroup that warrants more frequent echocardiographic follow-up.

A Prospective Study

Background: The objective of the study was to evaluate the early outcomes and survival in patients with severe aortic stenosis associated with concentric left ventricular hypertrophy following aortic valve replacement.Methods: This is a prospective study done at SVIMS, Tirupati, from June 2014 to September 2015 evaluating out comes and survival in patients undergoing primary isolated aortic valve replacement (AVR) for severe aortic stenosis, severe aortic stenosis with mild aortic regurgitation and severe aortic stenosis with moderate aortic regurgitation.Results: A total of 40 cases 26 males and 14 females aged 18 to 60 years (mean age, 48.5±13.4 years) underwent elective AVR. Left ventricular end diastolic diameter (p=0.008) at 6 months, a statistically highly significant difference in left ventricular mass  preoperatively, at discharge, at 3rd and 6th month follow up. The difference in mean left ventricular mass index (LVMI) had declined from 244.425 to 141.100 at 6 months, showing a statistically highly significant difference in LVMI preop, at discharge, at 3rd month and at 6th month follow up.Conclusions: Patients with preoperative increase in LVMI, with large left atrial diameter carries a strong predictor of postoperative mortality for patients undergoing aortic valve surgery. We also conclude that there will be significant regression of LVMI following successful AVR. But, the decrease in LVMI is maximum during early three months and it is minimal though significant in the later course of follow up.

Abstract Background: It is unclear whether increased left ventricular (LV) thickness is associated with worse clinical outcomes in severe aortic stenosis (AS). The aim of this study was to determine the effect of increased LV wall thickness (LVWT) on major clinical outcomes in patients with severe AS.Methods and Results: This study included 290 severe AS patients (mean age 69.4 ± 11.0 years; 136 females) between January 2008 and December 2018. For outcome assessment, the endpoint was defined as death from all causes, cardiovascular death, and the aortic valve replacement (AVR) surgery rate. During follow-up (48.7 ± 39.0 months), 157 patients had AVR, 43 patients died, and 28 patients died from cardiovascular causes. Patients with increased LVWT underwent AVR surgery much more than those without LVWT (60.0% vs. 39.0%, p < 0.001). Furthermore, in patients with increased LVWT, the all-cause and cardiovascular death rates were significantly lower in the AVR group than in the non-AVR group (8.8% vs. 27.3%, p < 0.001, 4.8%, vs. 21.0%, p < 0.001). Multivariate analysis revealed that increased LVWT, age, dyspnea, and AVR surgery were significantly correlated with cardiovascular death. Conclusions: In patients with severe AS, increased LVWT was associated with a higher AVR surgery rate and an increased rate of cardiovascular death independent of other well-known prognostic variates. Thus, these findings suggest that increased LVWT might be used as a potential prognostic factor in severe AS patients.

Abstract Introduction Aortic valve (AV) stenosis is the most common type of congenital left ventricular outflow tract obstruction. Short-term outcomes following balloon aortic valvuloplasty (BAV) including residual aortic stenosis, aortic insufficiency, and procedural complications have been established. The impact of pre-intervention AV characteristics on long-term outcomes has not been well studied. Purpose The aim of this study was to determine the relationship between the initial parameters on baseline echocardiogram and the time to reintervention in children with AV stenosis following BAV. Methods Children from the newborn period to 18 years of age with AV stenosis who underwent BAV from 2004-2012 were included. Patients with aortic insufficiency prior to BAV, complex congenital heart lesions, or less than two accessible follow-up echocardiograms were excluded. Baseline and serial echocardiographic data pertaining to aortic valve and LV size and function was retrospectively collected until December 2017 or until the first reintervention. Time to reintervention or death was evaluated. Results Among the 98 enrolled patients, the median [IQR] age at BAV was 2.8 months [0.2-75]. The median [IQR] duration of follow-up was 6.8 [1.9-9.0] years. Eighty-nine (83%) patients had bicuspid valve morphology and the median [IQR] peak-to-peak catheterization gradient prior to BAV was 49 [34-65] mmHg. The cumulative proportion [95% CI] of reintervention at 5 years following BAV was 33.7% [23.6%, 42.4%]. Primary indications for reintervention were aortic stenosis (57%), aortic insufficiency (14%), or mixed valve disease (30%). Reinterventions included repeat BAV (49%), AV repair (15%), and AV replacement (36%). Increased LVEF at baseline as well as increased mean LV circumferential strain at baseline were associated with decreased risk of reintervention (HR [95% CI] (1 unit increments): 0.974 [0.959-0.989], p &lt; 0.001; 0.939 [0.884-0.997], p = 0.041 respectively). Increased AV annulus z-score was also associated with decreased risk of reintervention (HR [95% CI] (1 unit increments): 0.806 [0.698-0.93], p = 0.003). Conclusions Our results demonstrate that better left ventricular function at baseline, measured by LVEF and mean LV circumferential strain, is associated with a decreased risk of reintervention in neonates and children following BAV. We have also shown that a bigger AV annulus prior to BAV is associated with a decreased risk of reintervention.

BackgroundContemporary data regarding the impact of comorbidities on the clinical presentation and management of patients with severe aortic stenosis (AS) are scarce.MethodsProspective registry of severe patients with AS across 23 centres in nine European countries.ResultsOf the 2171 patients, chronic kidney disease (CKD 27.3%), left ventricular ejection fraction (LVEF) <50% (22.0%), atrial fibrillation (15.9%) and chronic obstructive pulmonary disease (11.4%) were the most prevalent comorbidities (49.3% none, 33.9% one and 16.8% ≥2 of these). The decision to perform aortic valve replacement (AVR) was taken in a comparable proportion (67%, 72% and 69%, in patients with 0, 1 and ≥2 comorbidities; p=0.186). However, the decision for TAVI was more common with more comorbidities (35.4%, 54.0% and 57.0% for no, 1 and ≥2; p<0.001), while the decision for surgical AVR (SAVR) was decreased with increasing comorbidity burden (31.9%, 17.4% and 12.3%; p<0.001). The proportion of patients with planned AVRs that were performed within 3 months was significantly higher in patients with 1 or ≥2 comorbidities than in those without (8.7%, 10.0% and 15.7%; p<0.001). Furthermore, the mean time to AVR was significantly shorter in patients with one (30.5 days) or ≥2 comorbidities (30.8 days) than in those without (35.7 days; p=0.012). Patients with reduced LVEF tended to be offered an AVR more frequently and with a shorter delay while patients with CKD were less frequently treated.ConclusionsComorbidities in severe patients with AS affect the presentation and management of patients with severe AS. TAVI was offered more often than SAVR and performed within a shorter time period.

OBJECTIVESTo examine long axis excursion in patients with all grades of aortic stenosis and preserved transverse systolic function, and to compare long axis excursion in symptomatic with that in asymptomatic severe aortic stenosis.DESIGNProspective comparative study.SETTINGRegional cardiothoracic centre.PATIENTS78 patients with all grades of aortic stenosis and normal fractional shortening and ejection fraction were studied. There were two comparison groups, 10 age matched normal subjects and 14 patients with aortic stenosis and fractional shortening < 26%.METHODSAortic valve function and left ventricular mass were assessed echocardiographically. M mode measurements of long axis excursion at the septal and lateral sides of the mitral annulus were taken.RESULTSThere were significant differences between the groups in long axis excursion at both the septal (p < 0.0001) and lateral sides of the mitral annulus (p = 0.002 by analysis of variance). Long axis excursion was independently related to both left ventricular mass index (p = 0.001) and the grade of aortic stenosis (p = 0.002). Comparing patients with severe aortic stenosis with and without symptoms, there were significant differences in effective orifice area (p = 0.02 ) and long axis excursion at the lateral side of the mitral annulus (p = 0.04), but not in fractional shortening, ejection fraction, or peak or mean pressure difference.CONCLUSIONIn patients with aortic stenosis, long axis excursion is reduced even in the presence of normal fractional shortening or ejection fraction. It is lower in patients with symptomatic compared with asymptomatic severe aortic stenosis and may be of use in predicting the onset of symptoms.
