Persistent left superior vena cava (LSVC) with absent right SVC (RSVC) is a rare congenital anomaly. If undetected, the condition may pose difficulties in central venous catheter insertion, pacemaker electrode insertion, and cannulation during cardiopulmonary bypass. We describe a case of persistent LSVC with absent RSVC, who was diagnosed to have bicuspid aortic valve with aortic stenosis.

BACKGROUND: The approach to intervention for congenital aortic valve stenosis (AS) differs depending upon centre bias toward a primary catheter or surgical approach. We therefore investigated associations with freedom from re-intervention (FFI) in the cohort of children who underwent primary balloon aortic valvuloplasty (BAV) for congenital AS in our centre. METHODS: All patients who underwent BAV as a primary procedure in the period between 2001 and 2015 in a single service were included...

With increased life expectancy and aging of the population, aortic stenosis is now one of the most common valvular heart diseases. Early recognition and management of aortic stenosis are of paramount importance because untreated symptomatic severe disease is universally fatal. The advent of transcather aortic valve replacement technologies provides exciting avenues of care to patients with this disease in whom traditional surgical procedures could not be performed or were associated with high risk. This review for clinicians offers an overview of aortic stenosis and updated information on the current status of various treatment strategies...

After an arterial switch operation (ASO), serial imaging is necessary to monitor for maladaptive changes. We compared cardiac magnetic resonance imaging (CMR) to 2-D transthoracic echocardiography (TTE) in assessing post-operative ASO patients. We performed a retrospective review of patients at a single tertiary care center who underwent an ASO and subsequently had a CMR performed from 7/2010 to 7/2016. Those with single ventricle anatomy, congenitally corrected transposition of the great arteries, or previous atrial switch operation were excluded...

BACKGROUND: Aortic stenosis has been reported to manifest a slow rate of progression in mild disease, with a greater likelihood of progression in patients with moderate-severe disease. The natural history of the Doppler-estimated maximum gradient (DEMG) in patients after balloon aortic valvuloplasty (BAVP) has not previously been studied on a large scale. METHODS AND RESULTS: A retrospective review was performed of 360 patients from 1984 to 2012 with aortic stenosis, providing a total of 2059 echocardiograms both before and after BAVP...

REVIEW
Michelle Carr, Stephanie Curtis, Jan Marek
Congenital obstruction of the left ventricular outflow tract remains a significant problem and multi-level obstruction can often co-exist. Obstruction can take several morphological forms and may involve the subvalvar, valvar or supravalvar portion of the aortic valve complex. Congenital valvar stenosis presenting in the neonatal period represents a spectrum of disorders ranging from the hypoplastic left heart syndrome to almost normal hearts. Treatment options vary dependent on the severity of the left ventricular outflow tract obstruction (LVOTO) and the variable degree of left ventricular hypoplasia as well as the associated lesions such as arch hypoplasia and coarctation...

OBJECTIVES: Supravalvar aortic stenosis (SVAS) is a rare congenital anomaly. The "single-patch technique," "'two sinus augmentation with an inverted Y-patch" (both nonsymmetrical corrections), "three-patch technique," and the "slide aortoplasty" (both symmetrical corrections) are the techniques implemented by the majority of surgeons for the correction of SVAS. In the few studies that compared these techniques, no technique was shown to be superior over another...

This article reviews important features to improve the diagnosis of congenital heart disease (CHD) by applying ultrasound in prenatal cardiac screening. As low and high-risk pregnancies for CHD are subject to routine obstetric ultrasound, the diagnosis of structural heart defects represents a challenge that involves a team of specialists and subspecialists on fetal ultrasonography. In this review, the images highlight normal anatomy of the heart as well as pathologic cases consistent with cardiac malposition and isomerism, septal defects, pulmonary stenosis/atresia, aortic malformations, hypoplastic left ventricle, conotruncal anomalies, tricuspid dysplasia, and Ebstein's anomaly, and univentricular heart, among other congenital cardiovascular defects...

Hypoplastic left heart syndrome (HLHS) is the second most common congenital heart disease associated with congenital diaphragmatic hernia (CDH). The reported survival rate of neonates with CDH and HLHS is only 1%-5%. We review our experience with CDH and HLHS and compare our outcomes with published literature. Retrospective review of all neonates with CDH and HLHS at our institution over a 10-year period was performed. The morphology of cardiac and diaphragm defects, clinical course, treatment strategies, and outcomes were reviewed, and an algorithmic approach was proposed...

Right ventricular outflow tract (RVOT) dysfunction is a common hemodynamic challenge for adults with congenital heart disease (ACHD), including patients with repaired tetralogy of Fallot (TOF), truncus arteriosus (TA), and those who have undergone the Ross procedure for congenital aortic stenosis and the Rastelli repair for transposition of great vessels. Pulmonary valve replacement (PVR) has become one of the most common procedures performed for ACHD patients. Areas covered: Given the advances in transcatheter technology, we conducted a detailed review of the available studies addressing the indications for PVR, historical background, evolving technology, procedural aspects, and the future direction, with an emphasis on ACHD patients...

We report a case of combined severe aortic stenosis and regurgitation in a pregnant patient with a history of congenital bicuspid aortic valve. The patient presented at 22 weeks of gestation with angina and pre-syncopal symptoms. During her admission, she experienced intermittent episodes of non-sustained ventricular tachycardia and hypotension. A multi-disciplinary healthcare team was assembled to decide on the appropriate medical and surgical treatment options. At 28 weeks of gestation, the patient underwent a caesarean delivery immediately followed by a mechanical aortic valve replacement...

BACKGROUND: Subaortic septal myectomy is usually performed to mitigate obstruction in patients with the obstructive form of hypertrophic cardiomyopathy (HCM) or in those with congenital subaortic stenosis. Moreover, it is combined with aortic valve replacement in patients with severe aortic valve stenosis (SAS) and asymmetrical septal hypertrophy causing concomitant left ventricular outflow tract obstruction. When both conditions coexist, it is conceptually difficult to identify a cardiomyopathy beyond an adaptive myocardial hypertrophy, strictly related to pressure overload...

BACKGROUND: The Adult Congenital Heart Surgery (ACHS) score was derived from the Society of Thoracic Surgeons Congenital Heart Surgery Database. The score was validated with data of 1,603 operations and reached a good predictive power. We sought to evaluate its predictive power on 1,654 operations performed in 2 European centers. METHODS: Data of all consecutive patients aged 18 years or more, who underwent surgery for congenital heart disease between 2004 and 2013 at Center 1 (n=830), and between 2005 and 2016 at Center 2 (n=824), were collected...

A retrospective review of admission preductal oxygen saturations of neonates with antenatally diagnosed critical congenital heart disease (CCHD) was performed to investigate the differences in newborn pulse oximetry (Pulsox) by specific CCHD diagnosis. Saturations were recorded at median of < 1 h (range < 1-9 h) after delivery. Data was stratified by CCHD diagnosis and analysed according to the three different admission Pulsox thresholds, ≤ 90, ≤ 92 and ≤ 95%. Of the 276 neonates studied, 208 were clinically well at admission, with no co-morbidities, gestation > 34 weeks and birth weight > 1...

BACKGROUND: The unicuspid aortic valve (UAV) is a well-described pediatric congenital abnormality, with incidence of 0.02% in the general population. Bicuspidization has been described as a potential surgical option to repair this defect. METHODS: Seventeen symptomatic young patients with a unicuspid valve combined with either valve insufficiency or valve stenosis underwent aortic valve bicuspidization procedure using either an equine pericardium. In addition to bicuspidization, eight patients underwent aortic ring implantation and five patients underwent supracoronary replacement of the aorta...

Subvalvular aortic stenosis (SAS) is one of the common adult congenital heart diseases, with a prevalence of 6.5%. It is usually diagnosed in the first decade of life. Echocardiography is the test of choice to diagnose SAS. Surgical correction is the best treatment modality, and the prognosis is usually excellent. In this review, we describe the pathophysiology, diagnosis, prognosis, and management of SAS with a focus on different pathophysiologic mechanisms, diagnostic approach, and prognosis of the disease by reviewing the current literature...

The use of balloon aortic valvuloplasty for congenital aortic valve stenosis was well established in literatures. However, balloon aortic valvuloplasty performed in low body weight neonates had been infrequently reported. Here we report a 5-day-old premature neonate diagnosed critical aortic valve stenosis. Balloon aortic valvuloplasty was performed as first-line therapy while the patient weighed only 1493 g. Balloon aortic valvuloplasty went successfully with transvalvular pressure gradient decreased from 80 mmHg to 44 mmHg...
