BACKGROUND: Hybrid procedure offers patients with severe congenital heart disease an alternative initial procedure to conventional surgical reconstruction. We report the midterm outcomes of a cohort of neonates who had a hybrid procedure for variants of hypoplastic left heart syndrome because they were at high risk for the Norwood procedure. METHODS: Between December 2005 and January 2013, 41 neonates underwent bilateral pulmonary artery banding followed by ductal stenting by means of a sternotomy at a median age of 6 days (range, 2 to 18 days) and weight of 2...

OBJECTIVES: Fetal cardiac interventions have the potential to alter natural disease progression and reduce morbidity and mortality in children. Although there are already encouraging data on fetal outcome, information on maternal morbidity and mortality after intervention is scarce. The aim of the present study was to assess maternal aspects, pregnancy-associated risks and adverse events in 53 intrauterine cardiac interventions. METHODS: Between October 2000 and December 2012, 53 fetal cardiac interventions were performed in 47 patients (43 aortic valve dilations in 39 patients, seven pulmonary valve dilations in six patients and three balloon atrioseptostomies in two patients)...

Fetal aortic balloon valvuloplasty (FAV) has shown promise in averting progression of midgestation aortic stenosis (AS) to hypoplastic left heart syndrome in a subset of patients. Patients who achieve biventricular circulation after FAV frequently have left ventricular (LV) diastolic dysfunction (DD). This study evaluates DD in fetuses with AS by comparing echocardiographic indices of LV diastolic function in fetuses underwent FAV (n = 20) with controls (n = 40) and evaluates for LV factors associated with DD in patients with FAV...

OBJECTIVE: The impact of prenatal intervention on fetal cardiac function has not been well defined. We assessed standard ventricular function parameters and strain in fetuses with evolving hypoplastic left heart syndrome (HLHS) treated with fetal aortic valvuloplasty (fAVP). METHODS: Fetuses with valvar aortic stenosis that underwent fAVP were studied. Echocardiographic images prior to intervention (Pre), within 1 week after fAVP (Post), and at the last prenatal follow-up examination (FU) were analyzed...

OBJECTIVE: Fetal cardiac interventions are performed via direct cardiac puncture and are associated with significant fetal morbidity. The feasibility of utilizing magnetic navigation to maneuver a guide wire and balloon across a fetal aortic valve without direct cardiac puncture is tested. METHODS: A fetal heart model was manufactured and placed in a catheterization laboratory equipped with magnetic navigation. Magnetically steerable guide wires along with commercially available coronary balloons were inserted into the model at a site mimicking a hepatic vein...

The mortality and morbidity of fetal aortic stenosis (AS) depend on the degree of the hemodynamic effects of the stenosis, and left ventricular (LV) adaptation, development and function during fetal life. In the case of critical AS, the development of hydrops and death in utero are well recognized entities. A 23-week gestation fetus was diagnosed with critical severe AS, cardiomegaly, a dilated LV with very poor contractility, and mitral regurgitation. There was a reversal of flow in the aortic arch through the ductus arteriosis and a reversed a-wave in the ductus venosus on Doppler examination...

OBJECTIVES: Foetal aortic valvuloplasty has been proposed as a strategy to improve left heart growth and function in foetuses with severe aortic stenosis at risk of progression to hypoplastic left heart syndrome. We report our experience with this intervention. METHODS AND RESULTS: Between 2005 and 2010, five foetuses with aortic stenosis and at risk of progression to hypoplastic left heart syndrome underwent ultrasound-guided percutaneous foetal aortic valvuloplasty...

Fetal cardiac interventions are being performed with growing success by a minimally invasive percutaneous and transthoracic approach. The primary aim of these interventions is to minimise postnatal morbidity and mortality, rarely also to achieve intrauterine survival. Valvuloplasty in utero for severe aortic stenosis is performed in order to achieve sufficient growth of the left ventricle and to make a later biventricular repair possible. In rare cases with hydrops secondary to massive left ventricular dilatation and mitral insufficiency it is used as a salvage therapy...

BACKGROUND: Intrauterine balloon aortic valvuloplasty (IUBAV) has been used for critical aortic stenosis. However, it is necessary to determine the fetal impairments such as preterm birth after this approach and to find a way to prevent or reduce them. METHODS: In the present study, we evaluated the therapeutic value of indomethacin (IDM) and dexamethasone (DXS) on reducing the preterm birth rate in experimental goats after IUBAV. RESULTS: Our results indicated that the administration of IDM/DXS significantly reduced the rate of premature birth...

Successful treatment of severe aortic (AS) or pulmonary valve (PS) stenosis by balloon valvuloplasty in term neonates is well-established. Sometimes, AS or PS diagnosed antenatally, progresses to severe left or right ventricular hypoplasia respectively. Successful fetal balloon valvuloplasty cannot be assumed to significantly change the natural history. In this review of premature infants, balloon valvuloplasty was used in extremely small babies. Five with severe AS (32 to 36 weeks, birth weight 1.4 to 1.9 kg) had percutaneous balloon aortic valvuloplasty during the first 10 days of life...

The idea of prenatal intervention in congenital heart defects was put forward over 20 years ago, arising from the observation that some forms of cardiac malformation progressed in severity as pregnancy advanced. The simultaneous development of minimally invasive catheter techniques in children, led to the concept of treating the foetal heart directly, in an attempt to prevent the changes which had been observed. Early efforts at prenatal valvuloplasty were largely set aside after poor results and the coincidental development of alternative, increasingly successful, postnatal surgical strategies...

Objectives. Multiple technical difficulties are encountered when a multidisciplinary team of subspecialists begins a minimally-invasive fetal cardiac interventional program. We describe the learning curve. Study Design. Ten pregnant sheep underwent ultrasound-guided balloon valvuloplasty of the aortic valve. Team members and their roles remained constant through the trial. The time between needle insertion and entrance of the left ventricle at the aortic root was recorded. F-test was used to assess significance (P ≤ ...

Prenatal aortic valvuloplasty is performed only in few perinatal centers in the world. Critical aortic stenosis which can lead to hypoplastic left heart syndrome or severe fetal heart failure with nonimmune hydrops is an indication for this procedure. Prenatal intervention can change the natural course of the disease. Authors present the first successful fetal balloon aortic valvuloplasty in Poland. It was performed in a 29-week fetus with critical aortic stenosis, severe impairment of left ventricular function, heart failure and fetal hydrops...

Fetal cardiac intervention for critical aortic stenosis (AS) with evolving hypoplastic left heart syndrome is performed in an attempt to maintain a biventricular circulation postnatally. The procedure has been hindered by technical challenges and poor candidate selection. We report here the novel use of a pressure guidewire during aortic valvuloplasty in a fetus at 21 weeks' gestation with critical AS and evolving hypoplastic left heart syndrome. Use of a pressure guidewire during fetal cardiac intervention offers several potential advantages over existing protocols...

BACKGROUND: Mitral valve dysplasia syndrome is a unique form of left-sided heart disease characterized by aortic outflow hypoplasia, dilated left ventricle, dysplastic/incompetent mitral valve, and a restrictive/intact atrial septum. Patients with this constellation of abnormalities have been managed in a variety of ways with overall poor outcomes. METHODS: We performed a retrospective review of all patients with mitral valve dysplasia syndrome to identify fetal echocardiographic markers predictive of outcomes...

Fetal aortic balloon valvuloplasty (FAV) has shown promise in altering in utero progression of aortic stenosis to hypoplastic left heart syndrome. In patients who achieve a biventricular circulation after FAV, left ventricular (LV) compliance may be impaired. Echocardiographic indexes of diastolic function were compared between patients with biventricular circulation after FAV, congenital aortic stenosis (AS), and age-matched controls. In the neonatal period, patients with FAV had similar LV, aortic, and mitral valve dimensions but more evidence of endocardial fibroelastosis than patients with AS...

Emile A Bacha
Fetal cardiac interventions performed by interventional cardiologists are currently in a clinical experimental phase. The 3 most frequent interventions are: 1) aortic balloon valvuloplasty for critical aortic stenosis with a small left ventricle or with a normal size left ventricle but poor function; 2) atrial septostomy for highly restrictive or intact atrial septum in hypoplastic left heart syndrome; and 3) pulmonary valvuloplasty for pulmonary atresia and hypoplastic right ventricle. Current impact on everyday congenital heart surgery practice is small, but may increase in the future...
