Assessment of pulmonary blood flow and cardiac output is critical in the postoperative management of patients with single-ventricle physiology or 2-ventricle physiology with intracardiac shunting. Currently, such hemodynamic data are only obtainable by invasive procedures, such as cardiac catheterization or the use of a pulmonary artery catheter. Ready availability of such information, especially if attainable noninvasively, could be a valuable addition to postoperative management.
Ebstein's anomaly remains a relatively ignored disease. Lying in the 'No Man's land' between congenital and valve surgeons, it largely remains inadequately studied. We report our short-term results of treating it as a 'one and a half ventricle heart' and propose that the true tricuspid annulus (TTA) 'Z' score be used as an objective criterion for estimation of 'functional' right ventricle (RV).
Many surgeons are hesitant to use interposition vein grafting in head and neck microvascular free flap surgery due to concerns for elevated risk of flap loss.
The persistent sciatic artery (PSA) is a remnant of the fetal circulatory system that is preserved in less than 0.1% of the population. Up to 60% of patients with this vascular anomaly will go on to development of a PSA aneurysm (PSAA), which can produce a variety of symptoms including neuropathy, claudication, and acute limb-threatening ischemia. Historical management is by open operation and interposition grafting, which can be highly morbid. We describe successful management of a large, symptomatic PSAA ...
Chylothorax is a rare but severe complication after pediatric cardiac surgery and is related to significant morbidity and mortality. It is suspected to be more frequent after single ventricle staged palliation procedures, but focused studies on chylothorax in patients with univentricular heart physiology are scarce.
What is the central question of this study? In this study, we investigated whether targeted ablation of cardiac sympathetic neurons (TACSN) could suppress myocardial infarction-induced adverse cardiac remodeling and left ventricle dysfunction. What is the main finding and its importance? TACSN significantly alleviated sympathetic remodeling and neuroendocrine activation, attenuated cardiac hypertrophy and fibrosis, and improved the left ventricular function. Thus, TACSN may have a beneficial effect on adver...
In this paper, we present a novel convolutional neural network (CNN) architecture to segment images from a series of short-axis cardiac magnetic resonance slices (CMRI). The proposed model is an extension of the U-net that embeds a cardiac shape prior and involves a loss function tailored to the cardiac anatomy. Our system takes as input raw MR images, requires no manual preprocessing or image cropping and is trained to segment the endocardium and epicardium of the left ventricle, the endocardium of the rig...
There are many variations of coronary anatomy encountered during coronary angiogram. Anatomy demonstrating a single coronary artery is a rare congenital coronary artery anomaly. The entire heart is supplied solely by a coronary artery with single coronary ostium. We present a rare case of single coronary artery arising from the right sinus of Valsalva. The patient had presented with atypical chest pain and a stress test was performed, which was abnormal. We proceeded with coronary angiography which showed a...
We aim to examine the effect of genetic syndromes and extracardiac anomalies (GS/EC) on single ventricle (SV) palliation with focus on hospital death, interstage mortality, and progression towards subsequent palliation stages.
A 38-year-old woman, 37+3 weeker was incidentally detected to have fetal cardiomegaly during 36 weeks ultrasound and referred for fetal echocardiogram. Antenatal history and anomaly scan were normal. Fetal echocardiogram showed heart rate of 153/min, sinus rhythm, situs solitus, levocardia, dilated right atrium and ventricle with venoatrial, atrioventricular and ventriculoarterial concordances. All cardiac valves were normal; cardiac crux was intact with separate mitral and tricuspid annuli (figure 1A-C and...
We sought to evaluate the impact of prenatal diagnosis on morbidity and mortality in single ventricle (SV) lesions. All consecutive patients with pre- or postnatally diagnosed SV physiology admitted to our centre between January 2001 and June 2013 were reviewed. Primary endpoints included survival until 30 days after bidirectional cavopulmonary connection (BCPC) without transplant or BCPC takedown. Prenatal diagnosis was performed in 160 of 259 cases (62%). After excluding all cases with termination of pre...
According to our clinical experience, the gold standard for ossicular chain reconstruction is the incus interposition, which has shown a very low percentage of extrusion in long-term follow-up with excellent audiological outcomes (except tympanosclerosis) in our patients. There is no study using transcanal approach for type 2 tympanoplasty with incus interposition. In order to achieve success in audiological outcomes after incus interposition, the incus needs to be lightened. In addition, the removal of inc...
Liver disease is a recognised complication of the Fontan procedure for cyanotic congenital heart disease. The Fontan procedure is a complex cardio-surgical procedure that diverts systemic venous blood in patients with univentricular hearts directly into the pulmonary arteries, bypassing the right ventricle. The operation has dramatically increased the survival of patients with single ventricle physiology, with 83% surviving to 20 years, without need for cardiac transplantation. This article is protected ...
We examined the perinatal outcomes and right ventricular function before pregnancy, during pregnancy, and after delivery in women with Ebstein's anomaly.
We present in this paper the application of a statistical shape model of the left ventricle (LV) built from transthoracic real time 3D echocardiography (3DE) to segment the LV endocardium and epicardium in cardiac magnetic resonance (CMR) images.
This study aimed to elucidate the diagnostic process, the associated anomalies and the perinatal outcomes of right aortic arch (RAA) in a group of low-risk patients. The obstetric imaging database and digital patient files were reviewed between January 2015 and June 2016. There were 12 RAA cases detected prenatally. Seven foetuses had an aberrant left subclavian artery and one foetus had mirror image branching. The prevalence of RAA was 1.8 in 1000. Invasive prenatal diagnosis was offered to patients and se...
Na channel α-subunit composition of the zebrafish heart and electrophysiological properties of Na current (I) of zebrafish ventricular myocytes were examined. Eight Na channel α-subunits were expressed in both atrium and ventricle of the zebrafish heart. Na1.5Lb, an orthologue to the human Na1.5, was clearly the predominant isoform in both chambers representing 65.2 ± 4.1% and 83.1 ± 2.1% of all Na channel transcripts in atrium and ventricle, respectively. Na1.4b, an orthologue to human Na1.4, f...
Ebstein anomaly is a rare malformation of the tricuspid valve of the heart. The malformed tricuspid valve may be incompetent, stenotic, or rarely, imperforate. Pregnant patients with Ebstein anomaly become a challenge for the physician in terms of management. We report a case in which patient delivered successfully with Ebstein anomaly. The only complication was breathlessness. Authors concluded that women with Ebstein anomaly can have successful outcomes of pregnancy with close monitoring.
Exposure of the fetus to a range of environmental stressors, including maternal undernutrition, is associated with an increased risk of death from cardiovascular disease (CVD) in adult life. This study aimed to determine the effect of maternal nutrient restriction in late gestation on the molecular mechanisms that regulate cardiac growth and development of the fetal heart. Maternal undernutrition resulted in a decrease in fetal glucose concentrations across late gestation, whilst fetal arterial POremained u...
Pedal fat grafting is a cosmetic procedure indicated to treat the functional and aesthetic sequelae of pedal fat pad atrophy. Fat grafting has been found to mitigate these symptoms, but the exact mechanism is unknown.
In fetuses with structurally normal heart and suboptimal fetal growth (SFG), umbilical artery vascular resistance increases as measured by umbilical artery pulsatility index (UA-PI). The objective of this study is to compare hemodynamic responses to SFG in fetuses with single ventricle (SV) and controls with structurally normal heart.
Bilateral internal thoracic artery (ITA) grafting is associated with improved survival. However, potential survival benefit of using two ITA`s in patients with chronic lung disease (CLD) is questionable due to their increased risk of sternal wound infection (SWI) compared to operations incorporating single ITA (SITA). The purpose of this study is to compare early and long-term outcome of bilateral internal thoracic artery (BITA) grafting to that of grafting with single internal thoracic grafts and vein graf...
Pulmonary arterial hypertension is a disease characterized by increased pulmonary vascular resistance and redox imbalance, leading to failure of right ventricle. Trapidil has been described to improve the redox balance and cardiac conditions.
