Percutaneous balloon aortic valvuloplasty (PBAV), which is used to treat symptomatic aortic stenosis, requires ionizing radiation and contrast agent for imaging guidance. The aim of the study is to evaluate the feasibility and effectiveness of ultrasound-guided PBAV in patients with aortic stenosis. This case series included 30 patients (14 males; mean age, 61.5 ± 4.5 years) with moderate/severe aortic stenosis treated with ultrasound-guided PBAV at the Ultrasound Department, Fuwai Hospital, Beijing, China, between January 2016 and July 2019. Cardiac function (New York Heart Association grade) was assessed before PBAV and 1 month after the procedure. Aortic peak jet velocity, aortic valve orifice area (AVA), mean transvalvular pressure gradient (MTPG), left ventricular end-diastolic diameter (LVDD), left ventricular ejection fraction (LVEF), and left ventricular end-systolic diameter (LVESD) were determined before and immediately after PBAV using Doppler echocardiography. Preprocedural cardiac function was grade I in 3 cases, grade II in 9 cases, grade III in 10 cases, and grade IV in 8 cases. Postprocedural cardiac function was grade I in 22 cases, grade II in 4 cases, and grade III in 4 cases, suggesting that cardiac function was improved by PBAV. Ultrasound-guided PBAV resulted in significant improvements (P<0.05) in aortic peak jet velocity (3.68 ± 0.811 m/s vs. 4.79 ± 0.63 m/s), MTPG (33.77 ± 13.85 mmHg vs. 54.54 ± 13.81 mmHg), AVA (1.96 ± 0.25 cm2 vs. 0.98 ± 0.12 cm2), LVEDD (51.90 ± 3.21 mm vs. 65.60 ± 6.81 mm), LVEF (63.46 ± 11.29% vs. 56.31 ± 11.04%), and LVESD (35.50 2.62 mm vs. 45.20 ± 2.42 mm). Ultrasound-guided PBAV is feasible and achieves good short-term effects in patients with aortic stenosis.

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.

A 8 years old boy presented with shortness of breath, cough and palpitation and subsequently diagnosed as a case of severe aortic stenosis with bicuspid aortic valve. Percutaneous balloon aortic valvuloplasty (PBAV) was done and he became asymptomatic. Post procedure his aortic valve area and aortic systolic pressure increased, transaortic pressure gradient decreased. So good result, lower cost, elimination of drawbacks of thoracotomy and cardiopulmonary bypass suggest in children percutaneous balloon aortic valvuloplasty should be the treatment of choice for patients with severe aortic stenosis.

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.
