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 ...
Segmentation of cardiac medical images, an important step in measuring cardiac function, is usually performed either manually or semi-automatically. Fully automatic segmentation of the left ventricle (LV), the right ventricle (RV) as well as the myocardium of 3D magnetic resonance (MR) images throughout the entire cardiac cycle (4D), remains challenging. This study proposes a deformable-based segmentation methodology for efficiently segmenting 4D (3D+t) cardiac MR images.
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...
Anomalous neurological development associated with congenital heart disease (CHD) has been reported as early as third trimester of fetal development. While several studies have characterized variations in CHD neurodevelopmental outcomes in early childhood, these reports are often confounded by postnatal factors such as surgical outcome. Recent studies have focused on the comparing neurological variations between fetuses with CHD and normal controls. In this work, we present a comparison of in-utero variatio...
Although all coronary anatomy in D-transposition of the great arteries may be "switchable," there are reports in the literature of early and late coronary obstruction following the arterial switch operation. The Damus-Kaye-Stansel procedure does not risk injury to the coronary arteries, and unlike the atrial switch, commits the left ventricle to the systemic circulation. We present a series of four neonates over 22 years with D-transposition of the great arteries and a concomitant coronary artery anomaly pr...
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.
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...
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.
Auricular reconstruction in patients with congenital microtia permits craniofacial balance and harmony, especially in patients with bilateral microtia. However, published techniques usually require skin grafting, which can lead to color mismatch and visible scarring. Some surgeons prefer to reconstruct the auricle of each side separately, which prolongs the complete cycle of surgery and increases suffering of the patient. In this study, we introduce a modified technique using single expanded flaps without s...
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.
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...
There is strong retrospective data demonstrating that BIMA grafting leads to better long-term survival as compared to LIMA grafting. However, this survival advantage was not corroborated by the interim results of the Arterial Revascularization Trial(ART). Today, there are barriers to widespread adoption of BIMA grafting. One of the main disadvantages of the use of BIMA grafts is the higher risk of DSWI. Deep sternal wound infections can be minimized by skeletonized harvesting of the IMA grafts, which preser...
Proper development of the great vessels of the heart, and septation of the cardiac outflow tract requires cardiac neural crest cells. These cells give rise to the parasympathetic cardiac ganglia, the smooth muscle layer of the great vessels, some cardiomyocytes and the conotruncal cushions and aorticopulmonary septum of the outflow tract. Ablation of cardiac neural crest cells results in defective patterning of each of these structures. Previous studies have shown that targeted deletion of the forkhead tran...
Obesity, defined as a body mass index of ≥30 kg/m , is the most common chronic metabolic disease worldwide and its prevalence has been strongly increasing. Obesity has deleterious effects on cardiac function. The purpose of this review is to evaluate the effects of obesity and excessive weight loss due to bariatric surgery on cardiac function, structural changes and haemodynamic responses of both the left and right ventricle.
