Abstract

Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined diastolic and systolic function of both ventricles using the Doppler-derived myocardial performance index (Tei index) in patients who underwent surgical repair of tetralogy of Fallot using a transannular patch. In this article we discuss the impact of pulmonary regurgitation on right ventricular function and clinical outcome, the role of echocardiographic imaging, and current management strategies for patients with pulmonary regurgitation after this treatment.
Methods: Sixty eight patients with tetralogy Fallot were studied in Shahid Rajaie referral Cardiovascular Center during 2003-2005. The studied population, 36 male and 32 female with a mean age of 7.5±4 years and a history of corrective surgery for tetralogy of Fallot using a transannular patch. These patients were randomly selected and assessed by Doppler echocardiography.
Results: Fifty-seven patients (84%) had mild to moderate pulmonary regurgitation, whereas 11 patients (16%) had severe pulmonary regurgitation. Right ventricular Tei index was significantly increased in patients with severe pulmonary regurgitation compared those with mild to moderate pulmonary regurgitation (0.54±0.18 vs 0.24±0.11, P<0.01). Left ventricular Tei index was increased in patients with severe pulmonary regurgitation compared those with mild to moderate pulmonary regurgitation (0.46±0.22 vs 0.32±0.14, P<0.05).
Conclusions: The findings of this study suggest that pulmonary regurgitation is a serious complication after repair of tetralogy of Fallot with a transannular patch. Delaying surgery in such patients risks irreversible ventricular function.

Abstract

Background: Balloon atrial septostomy is an emergent procedure in pediatric cardiology. Nowadays, most patients in need of the procedure have acceptable outcomes after surgical repair. Thus, it is important to perform this procedure as safe as possible. By performing early arterial switch operation and prostaglandin infusion, the rate of balloon atrial septostomy has markedly decreased. However, not all centers performing early arterial switch repairs have abandoned atrial septostomy, even in patients who respond favorably to prostaglandin infusion.
Case presentation: In total, eight 1- to 15-day old term neonates admitted in Shahid Rajaee Heart Center in Tehran, Iran from October 2009 to February 2011, with congenital heart diseases were scheduled for balloon atrial septostomy. In six cases the procedure was done exclusively under echocardiographic guidance and in two cases with the help of fluoroscopy. Success was defined as the creation of an atrial septal defect with a diameter equal to or more than 5 mm and ample mobility of its margins.
Results: Male sex was predominant (87%) and the mean age of the neonates was six days. The diagnosis in all cases was simple transposition of great arteries. The procedure was successful in all patients with any cardiovascular complication.
Conclusion: Balloon atrial septostomy is an emergent procedure that can be done safely and effectively under echocardiographic guidance. According to the feasibility of this technique it could be performed fast, safe and effective at bedside, avoiding patient transportation to hemodynamic laboratory or referral center.

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
