AbstractPulmonary valve stenosis is common in patients with Noonan’s syndrome. The response to balloon valvoplasty varies.We assessed the correlation between re-intervention rate, immediate response, and the progress of the valve gradient over time after intervention.MethodsThis is a retrospective study conducted from 1995 to 2014.ResultsOf 14 patients identified, seven had re-intervention 28±54 months (range 3–149, median 3.3) after valvoplasty. These patients did not have a significant decrease in gradient after intervention. Their gradient subsequently decreased during follow-up and then became static before increasing years after intervention. In contrast, the gradient of patients not requiring further intervention continually reduced over time. Demographics did not differ between these groups.ConclusionWe could not identify predisposing factors for long-term success of pulmonary valvoplasty in Noonan’s patients, but the trajectory of gradients differs significantly between patients needing re-intervention from those who remain free from re-intervention.

AbstractIntroductionPercutaneous balloon valvuloplasty is the primary treatment for critical pulmonary valve stenosis in neonates. Thus far, a few studies have reported long-term results of this technique in neonatal critical pulmonary valve stenosis.MethodsWe carried out a retrospective study of all consecutive newborns with critical pulmonary valve stenosis subjected to percutaneous balloon valvuloplasty at a single centre, between 1994 and 2014, to assess its immediate and long-term safety and efficacy.ResultsA total of 24 neonates presented with critical pulmonary valve stenosis. The mean diameter of the pulmonary annulus was 7 mm (±1.19); 33.3% had a dysplastic pulmonary valve, and 92% were started on prostaglandin E1 treatment. Percutaneous balloon valvuloplasty was performed at a mean age of 4.0±4.3 days using, on average, a balloon-to-pulmonary annulus ratio of 1.18 mm (with a range from 0.9 to 1.43). Immediate success was achieved in 22/24 patients (92%) with a reduction in the pulmonary transvalvular peak gradient (p<0.05) and in the right ventricle/systemic pressure ratio (p<0.05). There was one death (4%) 6 days after the procedure, and 29.2% of them had transient rhythm complications. For a mean follow-up time of 8.4 years, the re-intervention rate was 42.9%. In total, 14 re-interventions were performed in nine neonates, including surgery in six. Freedom from re-intervention was 50% at 8 years and 43% at 10 and 15 years.ConclusionThis series, to the best of our knowledge, has had the longest follow-up of neonates with critical pulmonary valve stenosis. Percutaneous balloon valvuloplasty is a safe and effective treatment, and in our study 75% of the patients were exclusively treated using this technique.

Percutaneous Balloon Valvuloplasty

This study is aimed to delineate readers with an overview of percutaneous balloon pulmonary valvuloplasty (PBPV) of pulmonary valve stenosis (PVS) and highlighting outcome based on influential and recent studies. It has been four decades since Kan et al first introduce PBPV. Since then, PBPV has recognized as a gold standard therapy for PVS of all ages. Nowadays, PBPV is practiced for a broad range of indication such as PVS, PV dysplasia and pulmonary atresia. Typically, PBPV is recommended when gradient across the PV is >50 mmHg. The procedure involves the placement of one or more balloon catheters across the stenotic PV with the guidance of a guidewire; thereafter, inflation of the balloons is done by pressure, thus producing valvotomy. Nowadays, PBPV is done by echocardiographic guidance, but previously, it was done by fluoroscopic guidance. The main disadvantage of fluoroscopy was the radiation injury of patients. The recently recommended balloon/annulus ratio is 1.2 to 1.25. Following the procedure, the dramatic reduction of pressure gradient, free motion of the PV leaflets with less doming, the rise of cardiac output have been noted, whereas complications may occur but are unusual and minimal. Significant predictors of restenosis include balloon/annulus ratio <1.2 and immediate post-PBPV gradient ≥30 mmHg. Only a few percentages of patients needed repeat PBPV. Long-term follow-up results are surprisingly excellent. In conclusion, it is our opinion that PBPV is equally successful in patients of all ages, while worldwide recognized studies prove the safety, feasibility, and effectiveness. However, for early detection of any complication, life-long clinical follow-up is mandatory.

AbstractBackgroundPulmonary balloon valvuloplasty is a safe and effective treatment for children with pulmonary valve stenosis. A few studies evaluate the long-term outcomes of the procedure, particularly the degree of pulmonary regurgitation. We evaluated the outcomes of children >1 year following valvuloplasty for pulmonary valve stenosis.MethodsA retrospective analysis of children with pulmonary valve stenosis following pulmonary balloon valvuloplasty at a single institution was performed. Clinic summaries, catheterisation data, and echocardiographic data were reviewed. Inclusion criteria were isolated pulmonary valve stenosis, age <19 years at the time of intervention, and at least one echocardiogram performed at least 1 year after valvuloplasty.ResultsA total of 53 patients met inclusion criteria. The median age at valvuloplasty was 0.4 years (0.01–10.6 years). The last follow-up was 4.8±2.3 years following valvuloplasty. The pre-valvuloplasty peak instantaneous gradient by echocardiography was 60.6±14.6 mmHg. The peak gradient at the first postoperative echocardiography was reduced to 25.5±12 mmHg (p<0.001), and further decreased to 14.8±15.8 mmHg (p<0.001) at the most recent follow-up. The degree of regurgitation increased from before valvuloplasty to after valvuloplasty (p<0.001) but did not progress at the most recent follow-up (p=0.17). Only three patients (5.7%) required re-intervention for increasing pulmonary stenosis (two surgical; one repeat balloon). No significant procedural complications occurred.ConclusionsPulmonary balloon valvuloplasty remains a safe and effective treatment for children with isolated pulmonary valve stenosis, with excellent long-term outcomes and no mortality. A few patients require further intervention. Long-term follow-up demonstrates decreased, residual stenosis. Patients have a small, acute increase in pulmonary regurgitation following valvuloplasty, but no long-term progression.

Abstract Introduction Laparoscopic fundoplication (LF) has almost completely replaced the open procedure performed for gastroesophageal reflux disease (GERD) and hiatus hernia (HH). Several studies have suggested that long-term results with surgery for GERD are better than a medical line of management. In this retrospective study, we outline our experience with LF over 10 years. Also, we analyze the factors that would help us in better patient selection, thereby positively affecting the outcomes of surgery. Patients and Methods In this retrospective study, we identified 27 patients (14 females and 13 males) operated upon by a single surgeon from 2010 to 2020 at our institution. Out of these, 25 patients (12 females and 13 males) had GERD with type I HH and 2 (both females) had type II HH without GERD. The age range was 24 to 75 years. All patients had undergone oesophago-gastro-duodenoscopy (OGD scopy). A total of 25 patients had various degrees of esophagitis. Two patients had no esophagitis. These patients were analyzed for age, sex, symptoms, preoperative evaluation, exact procedure performed (Nissen’s vs. Toupet’s vs. cruroplasty + gastropexy), morbidity/mortality, and functional outcomes. They were also reviewed to examine the length of stay, length of procedure, complications, and recurrent symptoms on follow-up. Symptoms were assessed objectively with a score for six classical GERD symptoms preoperatively and on follow-up at 1-, 4- and 6-weeks postsurgery. Further evaluation was performed after 6 months and then annually for 2 years. Results 14 females (53%) and 13 males (48%) with a diagnosis of GERD (with type I HH) and type II HH were operated upon. The mean age was 46 years (24–75 years) and the mean body mass index (BMI) was 27 (18–32). The range of duration of the preoperative symptoms was 6 months to 2 years. The average operating time dropped from 130 minutes for the first 12 cases to 90 minutes for the last 15 cases. The mean hospital stay was 3 days (range: 2–4 days). In the immediate postoperative period, 72% (n = 18) of the patients reported improvement in the GERD symptoms, while 2 (8%) patients described heartburn (grade I, mild, daily) and 1 (4%) patient described bloating (grade I, daily). A total of 5 patients (20%) reported mild dysphagia to solids in the first 2 postoperative weeks. These symptoms settled down after 2 to 5 weeks of postoperative proton-pump inhibitor (PPI) therapy and by adjusting consistency of oral feeds. There was no conversion to open, and we observed no perioperative mortality. There were no patients who underwent redo surgeries in the series. Conclusion LF is a safe and highly effective procedure for a patient with symptoms of GERD, and it gives long-term relief from the symptoms. Stringent selection criteria are necessary to optimize the results of surgery. Experience is associated with a significant reduction of operating time.

Pulmonary Valve Replacement

Abstract OBJECTIVES Chronic pulmonary valve (PV) regurgitation is a common late sequela after repair of congenital heart diseases like tetralogy of Fallot or pulmonary stenosis, leading to right ventricular dilatation and failure and increased late morbidity and mortality. Timely reoperation may lead to a complete right ventricular recovery. An injectable PV allows pulmonary valve replacement, with or without cardiopulmonary bypass, under direct observation, thereby minimizing the impact of surgery on cardiac function. The aim of this study was to evaluate the feasibility and mid- to long-term clinical outcomes with this device. METHODS From April 2007 to October 2019, a total of 85 symptomatic patients with severe pulmonary regurgitation or pulmonary stenosis underwent pulmonary valve replacement with an injectable stented pulmonary prosthesis. Data were collected from the international proctoring registry. Mean patient age was 26.7 years. The underlying diagnosis was repaired tetralogy of Fallot in 69.4% patients; moderate or severe pulmonary regurgitation was present in 72.9%. All patients had echocardiographic scans before the operation and during the follow-up period. A total of 54.1% patients also had preoperative/postoperative cardiac magnetic resonance imaging (MRI) or catheterization; 25.9% had off-pump implants. In 53% patients, pulmonary valve replacement was associated with the repair of other cardiac defects. RESULTS Minor postoperative complications were observed in 10.8% patients. The overall mortality rate was 2.3%; mortality after valve replacement was linked to a severe cardiac insufficiency and it was not related to a prosthesis failure; 1 prosthesis was explanted from 1 patient because of endocarditis, and 6% of patients developed PV stenosis; minor complications occurred in 4.8%. The mean follow-up period was 4.8 years (2 months–12.7 years); 42% of the patients were followed for more than 5 years. Follow-up echocardiography and cardiac MRI showed a significant reduction in RV size and low gradients across the PV. CONCLUSIONS An injectable PV may be implanted without cardiopulmonary bypass and in a hybrid operating theatre with minimal surgical impact. The bioprosthesis, available up to large sizes, has a low profile, laminar flow and no risk of coronary artery compression. Incidence of endocarditis is rare. The lack of a suture ring permits the implant of a relatively larger prosthesis, thereby avoiding a right ventricular outflow tract obstruction. This device permits future percutaneous valve-in-valve procedures, if needed. Results concerning durability are encouraging, and mid- to long-term haemodynamic performance is excellent.
