Project description:BackgroundPercutaneous balloon pulmonary valvuloplasty is the procedure of choice for uncomplicated severe or symptomatic pulmonary stenosis. The present study describes our experience in balloon pulmonary valvuloplasty using the Inoue balloon catheter in adolescent and adult patients.AimsTo assess the immediate and mid-term outcomes of percutaneous balloon valvuloplasty with Inoue balloon catheter in adolescent and adult patients.Methods and resultsBetween June 2010 and July 2015, we performed percutaneous balloon pulmonary valvuloplasty with Inoue balloon catheter in 32 patients (59.37% females) aged 8 to 54 years (mean 23.6±11.5). Following the procedure, the mean right ventricular systolic pressure and the pulmonary valvular peak-to-peak systolic gradient decreased from (121.6±42.4 to 61.19±24.5mmHg, p=0.001) and (100.9±43.3 to 36.4±22.5mmHg, p=0.001), respectively. Twenty patients (Group A) showed immediate optimal results with post-procedure peak systolic gradient <36mmHg while 12 patients (Group B) had suboptimal results. An increase in pulmonary regurgitation by one grade was detected in 17 patients (53.2%). Twenty-three patients available for follow-up (mean duration, 2.75 years [range 0.25-5 years]) had a mean residual peak gradient of 23.6±2.51mmHg on Doppler echocardiography with attenuation of reactive RVOT stenosis in all Group B patients. There was no further increase in grade of pulmonary regurgitation or restenosis on mid-term follow-up.ConclusionPercutaneous Inoue balloon technique is an attractive alternative with excellent mid-term results for adolescents and adults with isolated pulmonary stenosis.

Project description: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.

Project description:Two juvenile alpacas, 1 male and 1 female, were presented for evaluation of grade V/VI bilateral basilar systolic heart murmurs. Both animals were ultimately diagnosed with severe valvular pulmonic stenosis and a small ventricular septal defect. Transvenous balloon valvuloplasty was performed in each animal using methods described in the dog. A double balloon technique was employed in the first case, with a balloon-annulus ratio of ~1.55. For the second case, a high-pressure dilatation balloon catheter with a balloon-annulus ratio of ~1.33 was selected. Experience with both procedures indicates that balloon pulmonary valvuloplasty is technically feasible in alpacas using techniques extrapolated from those used in dogs. Furthermore, accepted criteria for procedural success were fulfilled for both alpacas, with more than a 50% reduction in the echocardiographically derived transpulmonic pressure gradient after intervention.

Project description:BackgroundAortic valve stenosis is the most common type of congenital left ventricular (LV) outflow tract obstruction. Balloon aortic valvuloplasty (BAV) has become the first-line treatment pathway in many centers. Our aim was to assess the trajectory of LV remodeling following BAV in children and its relationship to residual aortic stenosis (AS) and insufficiency (AI).MethodsChildren <18 years of age who underwent BAV for isolated aortic stenosis from 2004 to 2012 were eligible for inclusion. Those with AI before BAV, other complex congenital heart lesions, or <2 accessible follow-up echocardiograms were excluded. Baseline and serial echocardiographic data pertaining to aortic valve and LV size and function were retrospectively collected through December 2017 or the first reintervention. Longitudinal data was assessed using per-patient time profiles with superimposed trend lines using locally estimated scatterplot smoothing. Associations with reintervention or death were also evaluated.ResultsAmong the 98 enrolled children, the median (interquartile range) age at BAV was 2.8 months (0.2-75). The median (interquartile range) follow-up was 6.8 years (1.9-9.0). Children with predominantly residual AI (n=11) demonstrated progressive increases in their LV end-diastolic dimension Z score within the first 3 years after the BAV, followed by a plateau (P<0.001). Their mean LV circumferential and longitudinal strain values remained within the normal range but lower than in the non-AI group (P<0.001 and P=0.001, respectively). Children with predominantly residual aortic stenosis (n=44) had no changes in LV dimensions but had a rapid early increase in mean LV circumferential and longitudinal strain. The cumulative proportion (95% CI) of reintervention at 5 years following BAV was 33.7% (23.6%-42.4%).ConclusionsOur study demonstrates that LV remodeling occurs mainly during the first 3 years in children with predominantly residual AI after BAV, with no subsequent significant functional changes over the medium term. These data improve our understanding of expected patient trajectories and thus may inform decisions on the timing of reintervention.

Project description:Whether balloon aortic valvuloplasty (BAV) may provide an effective palliation in symptomatic high-risk patients is uncertain. Therefore, we aimed to evaluate outcomes in symptomatic high-risk patients with severe aortic stenosis (AS), who underwent BAV. All-cause mortality and length of hospitalization for heart failure (HF) up to death or to 1-year follow up were collected after BAV. One hundred thirty-two (132) patients (62% women), mean age 85±7 years, underwent BAV with a substantial reduction of the peak-to-peak aortic gradient from 53±21 to 29±15 mmHg (p<0.001). The median of days of HF hospitalization prior to BAV was 9 (0-19), and decreased after BAV to 0 (0-9), p<0.001. During 1-year follow-up patients with untreated CAD (85, 64%) had a higher mortality compared to patients with insignificant/treated CAD (47, 36%): 1-year survival: 45±7% vs. 66± 7%; p=0.02. After adjustment for STS risk score and severity of residual AS, patients with untreated CAD remained at higher risk of mortality (adjusted HR 1.74 [1.01-2.91]; p=0.04). Thus, in this series of symptomatic high-risk patients, BAV was associated with a significant reduction in aortic valve gradient and hospitalization time for HF post-BAV. In patients with significant CAD, percutaneous intervention might be considered in order to improve survival.

Project description:Percutaneous balloon pulmonary valvuloplasty (BPV) is the mainstay of treatment for significant pulmonary stenosis with doming leaflets. Various techniques have been described in the literature including the use of Inoue Percutaneous Transseptal Mitral Commissurotomy (PTMC) catheter with standard 0.025? guidewire. But if right ventricular anatomy is not suitable, 0.025? guidewire doesn't provide enough support to track the Inoue PTMC catheter. Here, we report a case of successful BPV using a novel technique of slenderizing the Inoue Percutaneous Transseptal Mitral Commissurotomy (PTMC) catheter over an Amplatz superstiff 0.035? guidewire. This technique may be useful during BPV in difficult right ventricular inflow and outflow tract anatomy in patients with congenital pulmonary valve stenosis.

Project description:Percutaneous ventricular assist device (PVAD) use in balloon aortic valvuloplasty (BAV) has been performed sporadically. The PVAD used was TandemHeart. A few cases were reported using Impella 2.5 device. We report the first case of Impella CP-assisted BAV. The use of PVAD has been contraindicated in severe aortic stenosis (AS). However, the various benefits of PVAD, including circulatory support and minimizing interruption of blood flow during balloon inflation, made its use attractive in high-risk BAV. We recommend that severe AS no more stays as a contraindication to the use of PVADs. <Learning objective: There are various benefits of using percutaneous ventricular assist devices (PVADs) during high-risk balloon aortic valvuloplasty (BAV). Benefits, including circulatory support and minimizing interruption of blood flow during balloon inflation, made its use attractive in high-risk BAV. We present the good outcome of using Impella CP device in one case of high-risk BAV. We recommend that severe aortic stenosis no more stays as a contraindication to the use of PVADs.>.

Project description:BackgroundOptimal initial treatment for congenital aortic valve stenosis in children remains unclear between balloon aortic valvuloplasty (BAV) and surgical aortic valvotomy (SAV).Methods and resultsWe performed a contemporary systematic review and meta-analysis to compare survival in children with congenital aortic valve stenosis. Secondary outcomes included frequency of at least moderate regurgitation at hospital discharge as well as rates of aortic valve replacement and reintervention. Single- and dual-arm studies were identified by a search of PubMed (Medline), Embase, and the Cochrane database. Overall 2368 patients from 20 studies were included in the analysis, including 1835 (77%) in the BAV group and 533 (23%) in the SAV group. There was no difference between SAV and BAV in hospital mortality (OR=0.98, 95% CI 0.5-2.0, P=0.27, I(2)=22%) or frequency of at least moderate aortic regurgitation at discharge (OR=0.58, 95% CI 0.3-1.3, P=0.09, I(2)=54%). Kaplan-Meier analysis showed no difference in long-term survival or freedom from aortic valve replacement but significantly more reintervention in the BAV group (10-year freedom from reintervention of 46% [95% CI 40-52] for BAV versus 73% [95% CI 68-77] for SAV, P<0.001). Results were unchanged in a sensitivity analysis restricted to infants (<1 year of age).ConclusionsAlthough higher rates of reintervention suggest improved outcomes with SAV, indications for reintervention may vary depending on initial intervention. When considering the benefits of a less-invasive approach, and clinical equipoise with respect to more clinically relevant outcomes, these findings support the need for a randomized controlled trial.

Project description:Standardization of care can reduce practice variation, optimize resource utilization, and improve clinical outcomes. We have created a standardized clinical assessment and management plan (SCAMP) for patients having balloon aortic valvuloplasty (BAV) for congenital aortic stenosis (AS). This study compares acute outcomes of BAV at our institution before and after introduction of this SCAMP.In this retrospective matched cohort study, each SCAMP patient was matched to four historical controls. Outcomes were categorized based on the combination of residual AS and aortic regurgitation (AR) as: (1) Optimal: gradient ? 35 mm Hg and trivial or no AR; (2) Adequate: gradient ? 35 mm Hg and mild AR; (3) Inadequate: gradient > 35 mm Hg and/or moderate or severe AR.All 23 SCAMP patients achieved a residual AS gradient ? 35 mm Hg; the median residual AS gradient for the SCAMP group was lower (25 [10-35] mm Hg) than in matched controls (30 [0-65] mm Hg; P = 0.005). The two groups did not differ with regard to degree of AR grade after BAV. Compared with controls, SCAMP patients were more likely to have an optimal result and less likely to have an inadequate result (52% vs. 34% and 17% vs. 45%, respectively; P = 0.02) CONCLUSIONS: A SCAMP for BAV resulted in optimal acute results in half of the initial 23 patients enrolled, and outcomes in this group were better than those of matched historical controls. Whether these improved acute outcomes translate into better long-term outcomes for this patient population remains to be seen.

Project description:Background:Best timing for coronary revascularization in patients with severe aortic stenosis (AS) who was a candidate for transcatheter aortic valve implantation (TAVI) is still matter of debate. Case summary:We here report the case of an 87-year-old man with severe AS presenting with non-ST-segment elevation myocardial infarction. Coronary angiography revealed a highly complex and calcific left main stem (LMS) lesion. Rotablation-assisted percutaneous coronary intervention (PCI) was attempted but was complicated by post-stenting rapidly evolving haemodynamic impairment. A rescue 'pacing-free' balloon aortic valvuloplasty (BAV) was performed to rescue the patients, allowing prompt restoration of cardiac output and coronary perfusion. Discussion:According to guidelines and preliminary evidence, decision should be performed case by case and based on the degree of severity and complexity of either AS or coronary disease. The strategy of treating coronary lesions first may limit the risk of potential ischaemic complications during TAVI. However, the downside of it is the risk of hemodynamic crash with potential catastrophic evolution in case of PCI complications in presence of severe AS. A 'bailout BAV' can be considered as a salvage-strategy in case of complex and complicated LMS-PCI in the context of severe AS and advanced status of haemodynamic impairment. This approach must be seen as very last resort, while appropriate pre-procedural planning is still highly recommended in order to prevent potentially fatal procedural complications in this fragile clinical setting.
