Balloon pulmonary valvotomy in severe dysplastic pulmonary valve restenosis: A novel maneuver for stabilizing balloon positioning.

ABSTRACT: Balloon pulmonary valvuloplasty (BPV) is an interventional procedure that has practically replaced the need of open-heart surgery in patients with severe valvular pulmonary stenosis. However, BPV in dysplastic pulmonary valve (PV) still remains a challenge in the current milieu of advanced technologies. We encountered a unique situation of severe restenosis of PV wherein the attempt to balloon dilate the valve was futile because no balloon remained stable at the level of the valve. This situation was overcome using a PDA device delivery sheath to keep the balloon positioned at the desired location.

Surgical Valvotomy Versus Balloon Valvuloplasty for Congenital Aortic Valve Stenosis: A Systematic Review and Meta-Analysis.

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.

Unusual right ventricle aneurysm and dysplastic pulmonary valve with mitral valve hypoplasia.

Project description:We report a newborn with an unusual combination of aneurysmally dilated thin-walled right ventricle with hypertrophy of the apical muscles of the right ventricle. There was narrow pulmonary annulus, pulmonary regurgitation, and hypoplasia of the mitral valve and left ventricle. We propose that this heart represents a partial form of Uhl's anomaly.

Silent patent ductus arteriosus incidentally found before balloon mitral valvotomy for severe rheumatic mitral stenosis.

Project description:Rheumatic heart disease (RHD) and congenital heart disease (CHD) rarely co-exist in the same patient. However, such associations are not unknown in areas where RHD is endemic. We report a rare combination of severe rheumatic mitral stenosis, severe pulmonary artery hypertension (PAH), and an incidental clinically silent patent ductus arteriosus (PDA). The patient was initially subjected to a balloon mitral valvotomy to assess if the resultant fall in PA pressure would alter the flow dynamics of the PDA. Since the ductal flow remained small and clinically inaudible, no further intervention was advised. The case highlights the importance of detailed echocardiographic examination in patients with RHD to detect co-existent CHD and logical decision making in their management. <Learning objective: A detailed echocardiographic examination is needed in all cases even when a diagnosis is apparent. Despite obvious rheumatic mitral stenosis, meticulous echocardiography revealed a small PDA, which was clinically silent. Since severe PAH can alter findings of PDA, we first performed balloon mitral valvotomy to see if resultant fall in PA pressure would alter the flow dynamics of PDA. Despite fall in PA pressures, the PDA flow remained trivial and it was clinically inaudible. Hence, no further intervention was advised.>.

New Pulmonary Valvuloplasty Technique by Use of an Hourglass-Shaped Balloon in 3 Adults with Severe Pulmonary Valve Stenosis.

Project description:Percutaneous balloon pulmonary valvuloplasty is the preferred therapy for pulmonary valve stenosis. However, the designs of the cylindrical balloons historically used for valvuloplasty have limitations, especially in patients who have large pulmonary annular diameters. The hourglass-shaped V8 Aortic Valvuloplasty Balloon may prove to be an effective alternative. The balloon has 2 large bulbous segments that are separated by a narrowed waist. The geometric shape is maintained throughout inflation, improving fixation and enabling broader leaflet opening. We present our first experience with the V8 balloon in 3 adults who had severe, symptomatic pulmonary valve stenosis. In addition to describing their cases, we detail our sizing technique for pulmonary valvuloplasty with the V8 balloon. Our successful results suggest that the V8 balloon is efficient and safe for balloon pulmonary valvuloplasty in adults with severe pulmonary valve stenosis.

Effect of Balloon-Expandable Transcatheter Aortic Valve Replacement Positioning: A Patient-Specific Numerical Model.

Project description:Transcatheter aortic valve replacement (TAVR) has emerged as a life-saving and effective alternative to surgical valve replacement in high-risk, elderly patients with severe calcific aortic stenosis. Despite its early promise, certain limitations and adverse events, such as suboptimal placement and valve migration, have been reported. In the present study, it was aimed to evaluate the effect of various TAVR deployment locations on the procedural outcome by assessing the risk for valve migration. The deployment of a balloon-expandable Edwards SAPIEN valve was simulated via finite element analysis in a patient-specific calcified aortic root, which was reconstructed from CT scans of a retrospective case of valve migration. The deployment location was parametrized in three configurations and the anchorage was quantitatively assessed based on the contact between the stent and the native valve during the deployment and recoil phases. The proximal deployment led to lower contact area between the native leaflets and the stent which poses higher risk for valve migration. The distal and midway positions resulted in comparable outcomes, with the former providing a slightly better anchorage. The approach presented might be used as a predictive tool for procedural planning in order to prevent prosthesis migration and achieve better clinical outcomes.

Percutaneous balloon valvuloplasty with Inoue balloon catheter technique for pulmonary valve stenosis in adolescents and adults.

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.

Simultaneous balloon aortic valvotomy and patent ductus arteriosus device closure in preterm newborn.

Project description:Multiple congenital heart disease in the small preterm newborn such as severe narrowing of aortic valve and patent ductus arteriosus (PDA) is a therapeutic challenge. We report successful transcatheter antegrade balloon dilatation of the aortic valve and device closure of the PDA in a 1700-gram preterm newborn. Meticulous planning and team work aids in such transcatheter intervention. <Learning objective: Preterm newborn babies rarely have multiple major structural cardiac lesions complicating the care. Transcatheter intervention for multiple congenital cardiac lesions such as severe valvular aortic stenosis and large patent ductus arteriosus in a small preterm baby is challenging but feasible. Precise anatomical diagnosis and meticulous planning is essential for successful intervention with minimum complications.>.
