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 < 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.

Introduction: The optimal treatment for congenital aortic stenosis (AS) is debated despite decades of experience with both balloon aortic valvuloplasty (BAV) and surgical aortic valve repair (SAV). While BAV has been the mainstay of therapy for AS, recent single-center reports suggest optimal results following SAV. Hypothesis: We propose that reintervention rates following SAV and BAV are equivalent. Methods: We queried Medline, EMBASE and Web of Science for eligible studies using the keywords: “congenital aortic stenosis”, “balloon valvotomy”, “aortic valve stenosis surgery” and “treatment outcome or reintervention”. Studies were excluded when cohort size was <20 pts, when follow-up was < 2.5 yrs from primary intervention, and when primary indication was not AS (e.g. SAV in the setting of aortic valve regurgitation (AR)). Outcomes analyzed included death, reintervention and moderate or severe AR. Analysis was performed using Comprehensive Meta Analysis v3 using random effects models. Results: A total of 20 studies were included in our meta-analysis: SAV alone (n=3), BAV alone (n=12), and both (n=5). The mean age at BAV was 3.1 years (range, 4 days - 7 years) with a mean follow-up duration of 6.8 years, while mean age at SAV was 2.8 years (range, 14.2 days - 7.1 years) with a mean follow-up duration of 9.1 years. Mortality rates following BAV and SAV were 12.3% (95% CI: 7.7 - 19.1) and 10.2% (95% CI: 7.0 - 14.5), respectively (p=0.27). Reintervention following initial procedure for treatment of AS was higher following BAV (35.7% [95% CI: 29 - 43.1]) compared to SAV (25.2% [95% CI: 19.9 - 31.3])(p=0.012). Long-term and mid-term follow-up in these studies showed moderate to severe AR was present in 24.1% and 28.1% of BAV and SAV patients, respectively. Conclusions: Notwithstanding publication bias, both survival rates and development of late AR following BAV and SAV are similar. However, reintervention rates are significantly higher following BAV compared to SAV.

Objective Due to its circular shape, the area of the proximal left ventricular tract (PLVOT) adjacent to aortic valve can be derived from a single linear diameter. This is also the location of flow acceleration (FA) during systole, and pulse wave Doppler (PWD) sample volume in the PLVOT can lead to overestimation of velocity (V1) and the aortic valve area (AVA). Therefore, it is recommended to derive V1 from a region of laminar flow in the elliptical shaped distal LVOT (away from the annulus). Besides being inconsistent with the assumptions of continuity equation (CE), spatial difference in the location of flow and area measurement can result in inaccurate AVA calculation. We evaluated the impact of FA in the PLVOT on the accuracy of AVA by continuity equation (CE) in patients with aortic stenosis (AS). Methods CE-based AVA calculations were performed in patients with AS once with PWD-derived velocity time integral (VTI) in the distal LVOT (VTILVOT) and then in the PLVOT to obtain a FA velocity profile (FA-VTILVOT) for each patient. A paired sample t-test (P < 0.05) was conducted to compare the impact of FA-VTILVOT and VTILVOT on the calculation of AVA. Result There were 46 patients in the study. There was a 30.3% increase in the peak FA-VTILVOT as compared to the peak VTILVOT and AVA obtained by FA-VTILVOT was 29.1% higher than obtained by VTILVOT. Conclusion Accuracy of AVA can be significantly impacted by FA in the PLVOT. LVOT area should be measured with 3D imaging in the distal LVOT.

Background: Aortic valve stenosis results from minor to severe degrees of aortic valve maldevelopment. This stenosis causes mild to severe obstruction of the left ventricular outflow . Objectives : to study the immediate and intermediate results of percutaneous balloon aortic valvuloplasty in patients with congenital valvular aortic stenosis . Type of the study: A prospective study. Methods: The study was done on thirty five patients with congenital valvular aortic stenosis who had percutaneous balloon aortic valvuloplasty  in Ibn Al- Bitar Center for Cardiac Surgery from May 2009 to February 2011. Results: Twenty seven patients were male (77.2%) and 8 patients were female (22.8%), male to female ratio 3.5/ 1, . The aortic valve was bicuspid in 18 patients (51.4%) while 17 patients ( 48.6%) had tricuspid aortic valve. Balloon aortic valvuloplasty was successful in 30 patients (85.7%),. Maximum peak instantaneous Doppler pressure gradient across the aortic valve 24 hours postprocedural echocardiography showed reduction which is statistically significant. New aortic regurgitation had occurred in 15 patients ( 42.8%), it was mild in 9 patients ( 25.6%), moderate in 5 patients ( 14.3%) and severe in 1 patient( 2.9%) which is statistically significant. The follow up of 12.57 ± 3.88 ( 3- 22) months after intervention was done for all patients using echocardiography Doppler study, reveal the maximum peak instantaneous Doppler pressure gradient  across the aortic valve was raised  which is statistically significant. The aortic regurgitation was present in 18 patients (51.4%) , it was mild in 9 patients (25.7%) , moderate in 6 patients (17.1%) and severe in 3 patients  ( 8.6%). No mortality had been reported during the procedure or on follow up.                                                                                  Conclusion: Aortic balloon valvuloplasty is safe and effective procedure in the treatment of congenital valvular aortic stenosis but mild aortic regurgitation is the most common immediate complication of aortic balloon dilatation and progressive aortic regurgitation is a major problem during the intermediate follow up.

The aim: We aimed to assess the feasibility and safety of performing balloon aortic valvuloplasty (BAV) with Valver balloon catheter (Balton, Poland) in adults with severe aortic stenosis as a bridge or palliative treatment. Materials and methods: We identified consecutive patients who underwent BAV procedures between May 2019 and March 2020 using Valver balloon catheters. Demographic data, medical history, and clinical characteristics were retrospectively collected in all study patients together with periprocedural data as well as 12-month follow-up data. Results: We included 18 patients. The mean population age was 78.1±8.9 years, and women were 61.1%. The most common co-morbidities were arterial hypertension (88.9%), dyslipidemia (83.3%), and coronary artery disease (72.2%). The baseline mean aortic valve pressure gradient was 49.94±27.02 mmHg and the mean aortic valve area (AVA) was 0.65±0.20 cm2. In all cases, the procedure was performed from the femoral access via the 8F sheath. Two Valver balloon catheter sizes were used 18x40mm (33.3%) and 20x40mm (66.7%). Three periprocedural complications were observed, and none was associated with the Valver balloon catheter per se. The transthoracic echocardiography after the procedure revealed a decrease in the mean pressure gradient of 11.1±8.85 mmHg, and an increase in AVA of 0.21±0.19 cm2. At 12-month follow-up, the mortality rate was 38.9%. Conclusions: BAV is a procedure increasingly performed in catheterization laboratories worldwide. This paper confirmed the relative safety of BAV with Valver balloon catheters in the modern era, showing a low incidence of valve and vascular complications.

Balloon aortic valvuloplasty (BAV) provides an excellent alternative to surgical intervention and has become the preferred intervention for initial palliation for aortic stenosis in neonates, infants, children, adolescents, and young adults. The elderly patients with calcific aortic stenosis do not benefit from BAV. With the exception of neonates, most patients can be discharged home within 24-hours of the procedure. Although there is definitive evidence for pressure gradient relief immediately after as well as at follow-up and postponement of surgical intervention following BAV, the progression of aortic insufficiency at late follow up remain a major concern. In the neonatal population, severe aortic insufficiency may develop requiring surgical intervention. Despite these limitations, balloon aortic valvuloplasty is currently considered as therapeutic procedure of choice in the management of congenital aortic stenosis in the pediatric and young adult population. Careful follow-up to detect recurrence of stenosis and development of significant aortic insufficiency is recommended.

<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.

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.
