Use of Large Balloon Catheter to Treat Infants With Pulmonary Valve Stenosis.

ABSTRACT: Balloon pulmonary valvuloplasty is a safe and effective treatment for isolated pulmonary valve stenosis. Several balloon catheters are available for this procedure in neonates and infants. However, obtaining additional vascular access for the double-balloon technique in this population is troublesome, and tricuspid valve injury is a concern. We used a TMP PED balloon catheter to perform valvuloplasty in 2 infants with isolated pulmonary valve stenosis. This thin-walled, relatively large 12-mm balloon catheter can be delivered through a small-diameter sheath. In both cases, the transpulmonary pressure gradient was reduced without causing any valvular or vascular injuries. Neither patient had recurrent pulmonary valve stenosis. Together, these cases highlight the suitability and feasibility of using the 12-mm TMP PED balloon catheter for treating young infants with valvular stenosis.

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.

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.

Culture of pulmonary artery endothelial cells from pulmonary artery catheter balloon tips: considerations for use in pulmonary vascular disease.

Project description:Endothelial dysfunction is a hallmark of pulmonary arterial hypertension (PAH) but there are no established methods to study pulmonary artery endothelial cells (PAECs) from living patients. We sought to culture PAECs from pulmonary artery catheter (PAC) balloons used during right-heart catheterisation (RHC) to characterise successful culture attempts and to describe PAEC behaviour.PAECs were grown in primary culture to confluence and endothelial cell phenotype was confirmed. Standard assays for apoptosis, migration and tube formation were performed between passages three to eight. We collected 49 PAC tips from 45 subjects with successful PAEC culture from 19 balloons (39%).There were no differences in subject demographic details or RHC procedural details in successful versus unsuccessful attempts. However, for subjects who met haemodynamic criteria for PAH, there was a higher but nonsignificant (p=0.10) proportion amongst successful attempts (10 out of 19, 53%) versus unsuccessful attempts (nine out of 30, 30%). A successful culture was more likely in subjects with a lower cardiac index (p=0.03) and higher pulmonary vascular resistance (p=0.04). PAECs from a subject with idiopathic PAH were apoptosis resistant compared to commercial PAECs (p=0.04) and had reduced migration compared to PAECs from a subject with portopulmonary hypertension with high cardiac output (p=0.01). PAECs from a subject with HIV-associated PAH formed fewer (p=0.01) and shorter (p=0.02) vessel networks compared to commercial PAECs.Sustained culture and characterisation of PAECs from RHC balloons is feasible, especially in PAH with high haemodynamic burden. This technique may provide insight into endothelial dysfunction during PAH pathogenesis.

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

Project description: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.

Left coronary ostial stenosis developing 15 months after transcatheter aortic valve replacement with balloon-expandable valve.

Project description:We present the case of an 82-year-old man whose left coronary ostium became obstructed 15 months after transcatheter aortic valve replacement (TAVR) with a balloon-expandable valve. The patient underwent TAVR for symptomatic severe aortic stenosis with no complications. Fifteen months after the initial TAVR, the patient complained of chest pain while exercising, and the exercise stress myocardial perfusion scintigraphy demonstrated the development of regional myocardial ischemia in the region of the left coronary artery. Coronary angiography implied severe stenosis in the ostium of the left coronary artery. Computed tomography angiography and intravascular ultrasonography indicated a soft tissue component along with stent struts, which was considered to cause delayed coronary obstruction. Our report emphasizes the importance of having a low threshold for clinically suspecting delayed coronary obstruction in patients who have undergone TAVR, even after several years of the procedure. <Learning objective:Delayed coronary obstruction (DCO) should be suspected in patients presenting with new ischemic symptoms after transcatheter aortic valve replacement (TAVR). DCO may occur even in the case of TAVR with a balloon-expandable prosthetic valve, on antithrombotic regimens, and several years after the initial procedure.>.

The safety and efficacy of balloon-expandable versus self-expanding trans-catheter aortic valve replacement in high-risk patients with severe symptomatic aortic stenosis.

Project description:AimTransfemoral Trans-catheter Aortic Valve Replacement (TF-TAVR) is a safe and effective therapy compared with surgical aortic valve replacement (SAVR) in patients across all risk profiles using balloon-expandable valves (BEV) and self-expanding valves (SEV). Our aim was to compare safety and efficacy of BEV vs. SEV in high-risk patients undergoing TF-TAVR.Methods and resultsWe searched PubMed, EMBASE, Clinicaltrials.gov, Scopus, and Web of sciences for studies on patients with severe aortic stenosis undergoing TAVR. Primary outcome was 30-day all-cause mortality. Secondary outcomes defined by Valve Academic Research Consortium 2 (VARC-2) criteria were also examined. Six studies with 2,935 patients (1,439 to BEV and 1,496 to SEV) were included. BEV was associated with lower risk of all-cause mortality (2.2% vs. 4.5%; RR: 0.51; 95% CI: 0.31-0.82; p < 0.006) and cardiovascular mortality [(2.5% vs. 4.3%; RR: 0.54; 95% CI: 0.32-0.90; p = 0.01) at 30 days compared with SEV. Implantation of more than one valve per procedure (0.78% vs. 5.11%; RR: 0.15; 95% CI: 0.07-0.31; p < 0.00001), and moderate/severe AR/PVL (2.5% vs. 9.01%; RR: 0.3; 95% CI: 0.17-0.48); p < 0.00001) were also lower in the BEV arm.ConclusionBEV TAVR is associated with reduced all-cause mortality (High level of GRADE evidence), cardiovascular mortality (very low level) at 30 days compared with SEV TAVR in high surgical risk patients. Data are necessary to determine if the difference in outcomes persists in longer-term and if the same effects are seen in lower-risk patients.Systematic review registrationidentifier, CRD42020181190.

Quadricuspid pulmonary valve associated with atrial septal defects and pulmonary stenosis.

Project description:A 1-month-old Hispanic female was referred to the cardiology service. During physical examination, a systolic ejection murmur at the pulmonic area was auscultated. The echocardiography evaluation of the pulmonary valve demonstrated a quadricuspid pulmonary valve (QPV) with slightly thickened leaflets, associated atrial septal defects and mild pulmonary stenosis. QPV is a rare congenital anomaly variant that can remain asymptomatic with few or non-hemodynamic alterations. Associations with structural or functional alterations have been reported. This is the first case of QPV that was diagnosed in a Hispanic newborn.
