Abstract
Background: Pulmonary valve stenosis (PS) is one of the most common congenital heart disease in children. Isolated pulmonary stenosis is the most common form of pulmonary stenosis. Isolated Pulmonary stenosis is responsible for 8 to 10 percent of congenital heart disease. Balloon valvuloplasty is the choice of treatment for this cardiac disease. One of the most important complications of this disease is pulmonary regurgitation in follow-up. The purpose of this study was to characterize the status of pulmonary regurgitation on follow-up after pulmonary valvuloplasty by balloon. Methods: We studied pulmonary regurgitation after balloon valvuloplasty retrospectively in children less than 14 years old age and isolated pulmonary stenosis. These patients had not complex congenital heart disease and admitted for balloon valvuloplasty during period of September 2001 to September 2011 in Shahid Rajaee Cardiovascular
Research Center. The mean time of follow-up was 7±2.5 years.
Results: Four hundred and fifty-eight patients with mean age of 10.3±8.6 months were studied. Two hundred and fifty-five patients were male and 230 were female. Right ventricular pressure was decreased from 82.3±42.2 mmHg before procedure to 45.2±22.4 mmHg after procedure (P= 0.043). Pressure gradient between right ventricle and pulmonary artery was decreased from 75.4±18.2 mmHg to 25.7±15.13 mmHg during procedure (P= 0.032). The day after procedure, 180 (37.1%) patients had no pulmonary regurgitation echocardiographic evaluation, 175 (36.08%) had mild, and 118
(24.3%) had moderate pulmonary regurgitation. In patients with moderate pulmonary regurgitation, 7 (0.14%) of those improve to severe pulmonary regurgitation. In echocardiographic exam, 12 (2.4%) patients had severe regurgitation the day after balloon valvuloplasty. During long-term follow-up (7±2.5 years) for 3 patient pulmonary valve replacement were performed. In our study, balloon to annulus ratio in three groups of pulmonary regurgitation (mild, moderate and sever) had significant correlation (P=0.012).
Conclusion: Pulmonary regurgitation was seen after balloon valvuloplasty in some patients.In most patients it had no symptoms and long-term follow-up is necessary

Abstract
Background: Congenital heart defects (CHD) are the most common type of birth defects. The main screening tests used to identify babies with congenital heart defects include prenatal echocardiography and postnatal clinical assessment. Routine pulse oximetry has been reported as an additional screening test that can potentially improve the early diagnosis of critical congenital heart disease (CCHD).
Methods: This study is a multi-stage evolutionary study that was conducted for 12 months from March 2021 to March 2022 at Pediatric Cardiovascular Research Center in Cardiovascular Institute, Isfahan, Iran. In the first phase, after identifying the topic and aims of the present study, questions were designed through the PICO method including (population, intervention, control, and outcomes). Then conducting systematic searches, the quality of all existing clinical guidelines (CG) of this field were evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument and a committee consisting of pediatric cardiologists and neonatologists in the field. Next, based on the opinions of experts, the quality of 1 out of 6 clinical guidelines for early detection of critical congenital heart disease at birth by pulse oximetry was assessed as optimal. Finally, the clinical guidelines draft was evaluated using the Delphi method and the panel of experts. After expert panel meetings and consensus between members, the final version of the guideline for early detection of critical congenital heart diseases at birth by pulse oximetry was developed.
|
Results: In the present study, criteria of clinical practice regarding the stages of newborn screening by pulse oximetry at birth were determined based on the evidence and health conditions and were presented in twenty-eight recommendations and six sections. The final recommendations were presented in the results section.
Conclusion: The finding of the present study showed that physicians, nurses, and midwives can apply the recommendations of this clinical guideline for the early detection and referral of neonates with critical congenital heart disease.
