Aortic Valvuloplasty

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.

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.

The Impact

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.

<p><b>Background:</b> Severe congenital aortic stenosis in infants is a life-threatening congenital heart anomaly that is typically treated using percutaneous balloon aortic valvuloplasty.</p><p><b>Methods:</b> The usual route is the femoral artery under radiographic guidance. However, this procedure may be limited by the small size of the femoral artery in low-weight infants. An infant weighing only 7 kg with severe aortic stenosis (peak gradient was 103 mmHg) was successfully treated with a novel approach, that is trans-ascending aorta balloon aortic valvuloplasty guided by transesophageal echocardiography.</p><p><b>Results:</b> The patient tolerated the procedure well, and no major complications developed. After the intervention, transesophageal echocardiography indicated a significant reduction of the aortic valvular peak gradient from 103 mmHg to 22 mmHg, no aortic regurgitation was found. Eighteen months after the intervention, echocardiography revealed that the aortic valvular peak gradient had increased to 38 mmHg and that still no aortic regurgitation had occurred.</p><p><b>Conclusions:</b> In our limited experience, trans-ascending aorta balloon aortic valvuloplasty for severe aortic stenosis under transesophageal echocardiography guidance effectively reduces the aortic peak gradient. As this is a new procedure, long-term follow up and management will need to be established. It may be an alternative technique to treat congenital aortic stenosis in low-weight patients.</p>

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.
