Successful management of living donor liver transplantation for biliary atresia with single ventricle physiology-from peri-transplant through total cavopulmonary connection: A case report.

Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx f...

Single-stage repair of double outlet right ventricle with subpulmonic ventricular septal defect (Taussig-Bing anomaly).

Double outlet right ventricle with subpulmonic ventricular septal defect is a very rare form of congenital heart disease. Surgical correction involves closure of the ventricular septal defect with baffling of blood flow from the left ventricle to the pulmonic valve and arterial switch of the usually side-by-side great arteries. In this tutorial, we present our surgical technique for single-stage repair of this complex anomaly.

"Interposition Vein Grafting in Head and Neck Free Flap Reconstruction".

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.

Embolic stroke in a postpartum patient with Fontan physiology.

In cardiac physiology, single ventricle typically refers to the presence of a dominant systemic ventricle along with a hypoplastic ventricle. The Fontan operation is used to repair the single ventricle by directing deoxygenated systemic venous flow to the pulmonary arterial circulation. Normal pregnancy physiology, particularly increased intravascular volume, increased heart rate, increased cardiac output, hypercoagulability and decreased systemic vascular resistance, can exacerbate cardiac disease in patie...

Endovascular Management of a Large Persistent Sciatic Artery Aneurysm.

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 ...

Exploring kinetic energy as a new marker of cardiac function in the single ventricle circulation.

Ventricular volumetric ejection fraction (VV EF) is often normal in patients with single ventricle circulations despite them experiencing symptoms related to circulatory failure. We sought to determine if kinetic energy (KE) could be a better marker of ventricular performance. KE was prospectively quantified using 4D flow MRI in 41 patients with a single ventricle circulation (aged 0.5 - 28 years) and compared to 43 healthy volunteers (aged 1.5 - 62 years) and 14 patients with left ventricular (LV) dysfunct...

Targeted ablation of cardiac sympathetic neurons attenuates adverse post-infarction remodeling and left ventricle dysfunction.

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...

Bretschneider and del Nido solutions: Are they safe for coronary artery bypass grafting? If so, how should we use them?

A variety of cardioplegic solutions are being used widely today to arrest the heart during coronary artery bypass grafting (CABG) and other cardiac operations. To minimize interruptions during the surgery for intermittent dosing of the cardioplegia and to facilitate less invasive cardiac procedures, single-shot solutions, including Bretschneider and del Nido solutions, have been introduced. This review examines the evidence regarding the safety and efficacy of Bretschneider and del Nido cardioplegia during ...

Single Coronary Artery Arising from the Right Sinus of Valsalva and the Role of Coronary Computed Tomography Angiography.

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...

Fully automated segmentation of the left ventricle in cine cardiac MRI using neural network regression.

Left ventricle (LV) structure and functions are the primary assessment performed in most clinical cardiac MRI protocols. Fully automated LV segmentation might improve the efficiency and reproducibility of clinical assessment.

Genetic and Extracardiac Anomalies are Associated with Inferior Single Ventricle Palliation Outcomes.

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.

Dilated superior vena cava in fetal echocardiographic three-vessel view: what lies ahead?

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...

Transcanal approach for type 2 tympanoplasty with incus interposition ossiculoplasty: our experience on 134 patients.

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...

Hepatocellular Carcinoma as a complication of vascular disease of the liver after Fontan procedure.

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.[1] 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 ...

Influence of pregnancy on cardiac function and hemodynamics in women with Ebstein's anomaly.

We examined the perinatal outcomes and right ventricular function before pregnancy, during pregnancy, and after delivery in women with Ebstein's anomaly.

A statistical shape model of the left ventricle from real-time 3D echocardiography and its application to myocardial segmentation of cardiac magnetic resonance images.

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.

Characteristics of prenatally detected right aortic arch cases in a single institution.

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...

Cardiac voltage-gated sodium channel expression and electrophysiological characterization of the sodium current in the zebrafish (Danio rerio) ventricle.

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...

Reoperation 7 years after sternal reconstruction with a porcine acellular dermal matrix.

The number of chest wall reconstructions with a biologic mesh is increasing, but its long-term durability is unproven. A 73-year-old man underwent a complex sternal reconstruction 7 years ago with porcine acellular dermal matrix after postoperative repair of his ruptured right ventricle after coronary artery bypass grafting. He recently presented with unstable angina. Cardiac catheterization showed occluded saphenous vein grafts, and the patient required repeat coronary artery bypass grafting. Upon re-ent...

Sudden Unexpected Death From Unusually Large Primary Cardiac B-cell Lymphoma.

Primary cardiac lymphomas represent approximately 1% to 2% of primary cardiac neoplasms and 5% of malignant cardiac neoplasms. Here we present a case of sudden unexpected death of a middle-aged male resulting from an unusually large cardiac B-cell lymphoma. The neoplasm infiltrated the myocardium of the right atrium and ventricle and, to a lesser extent, the wall of the left atrium and pulmonary trunk. Extensive infiltration of the heart by the primary cardiac lymphoma, combined with the complete lack of sy...

Coronary artery bypass grafting in children.

We present our clinical experience with coronary artery bypass grafting (CABG) in children.

Maternal undernutrition in late gestation increases IGF2 signalling molecules and collagen deposition in the right ventricle of the fetal sheep heart.

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...

Mirror Anomaly in Dirac Semimetals.

We demonstrate that, apart from the chiral anomaly, Dirac semimetals possess another quantum anomaly, which we call the mirror anomaly and which manifests in a singular response of the Dirac semimetal to an applied magnetic field. Namely, the anomalous Hall conductivity exhibits step-function singularities when the field is rotated. We show that this phenomenon is closely analogous to the parity anomaly of (2+1)-dimensional Dirac fermions, but with mirror symmetry, which we demonstrate emerges near any Dira...
