The crocodilian cardiovascular design with a four-chambered heart and a left aorta that emerge from the right ventricle allows blood to be shunted away from the lungs, a right-to-left (R-L) shunt. The adaptive significance of this R-L shunt remains both poorly understood and controversial with particular debate on its putative role during digestion. Here we measure blood flow patterns in the right aorta (RAo), left aorta (LAo) and the coeliac artery (CoA) of undisturbed American alligators (Alligator mississippiensis) during fasting and throughout most of the digestive period...

BACKGROUND: Anatomic correction of corrected transposition of the great arteries with associated lesions, utilizing the morphologic left ventricle as a systemic pumping chamber, is the preferred method in many centers. The purpose of this study was to analyze functional outcome after anatomic correction. METHODS: Between Jan 1997 and May 2016, 63 patients with corrected transposition of the great arteries and associated lesions underwent anatomic correction. Forty-two patients (67%) underwent palliation before correction, including 14 patients (22%) who required training of systemic ventricle...

BACKGROUND: Development of a high-fidelity cardiac surgery simulator (CSS) requires integration of a heart model with a mock cardiopulmonary bypass (CPB) circuit that can provide feedback to mimic the pathophysiology of cardiac surgery. However, the cost of commercially available simulators precludes regular use. We describe steps in the construction of a high-fidelity CSS that integrates a pulsatile paracorporeal ventricular-assist device (Pulse-VAD) and a commercially available CPB simulator...

A 27 years old female was admitted to our hospital with complaints of swelling of feet and abdomen, pain abdomen and exertional dyspnea from last 1 week. On examination she was found to have congestive heart failure. Chest x-ray revealed mild cardiomegaly with left pleural effusion and electrocardiography showed right axis deviation with right ventricular hypertrophy. By echocardiography she was diagnosed to have double chambered right ventricle without any other congenital heart anomaly. She was started on medical treatment following which she recovered well and she was advised for surgery...

OBJECTIVES: In 2 subtypes of functional single ventricle, double inlet left ventricle (DILV) and tricuspid atresia with transposed great arteries (TA-TGA), systemic output passes through an outflow chamber before entering the aorta. Intracardiac obstruction to this pathway causing systemic outflow tract obstruction (SOTO) may be present at birth or develop over time. Long-term survival after Fontan has not been defined. We defined outcomes utilizing records from 2 centres that were cross-checked with data from a bi-national Fontan Registry for completeness and accuracy...

Double-chambered left ventricle (DCLV) is a particularly rare congenital entity characterized by the presence of two ventricular cavities separated by an abnormal muscle band. An asymptomatic 15-year-old boy was referred to our hospital because of electrocardiographic (ECG) abnormalities. His initial transthoracic echocardiography (TTE) demonstrated a DCLV with mild left ventricular systolic dysfunction. During a 5-year follow-up period, he remained symptom free with no changes in ECG and conventional TTE findings...

Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally...

Caring for the critically ill patient with acute right ventricle (RV) failure is a diagnostic and management challenge. A thorough understanding of normal RV anatomy and physiology is essential to manage RV failure. Despite the fact that the RV is essentially a volume chamber that ejects into a low-pressure system, the left ventricle contributes significantly to RV function through maintenance of the transseptal gradient (TSG). Preserving systemic mean arterial pressure maintains the TSG and RV perfusion. Various pathological states cause acute RV failure by decreasing the TSG and RV perfusion and/or increasing pulmonary vascular resistance...

The paper presents the management of a child born with pulmonary valve atresia, a single (double-inlet) ventricle, right ventricular hypoplasia, and perimembranous septal defect. The first stage of treatment consisted in a Blalock-Taussig shunt. Control angiography performed 1 year after surgery confirmed that the anastomosis was correct, and there was no narrowing at the connection. The first stage of treatment was complicated by the occlusion of the left pulmonary artery, as diagnosed during cardiac catheterization before the planned bidirectional Glenn anastomosis...

Cardiac neural crest cell (CNCC) ablation creates congenital heart defects (CHDs) that resemble those observed in many syndromes with craniofacial and cardiac consequences. The loss of CNCCs causes a variety of great vessel defects, including persistent truncus arteriosus and double-outlet right ventricle. However, because of the lack of quantitative volumetric measurements, less severe defects, such as great vessel size changes and valve defects, have not been assessed. Also poorly understood is the role of abnormal cardiac function in the progression of CNCC-related CHDs...

Double-chambered left ventricle (DCLV) is a rare congenital abnormality in which the left ventricle is divided into two separate chambers by a septum or anomalous muscular structure. The chambers are observed mostly parallel to each other without stenosis, and less frequently in a superior-inferior arrangement. An asymptomatic girl is presented here who was diagnosed with DCLV on echocardiographic examination that was performed for the evaluation of cardiac murmur detected by a pediatrician. She has been followed up without treatment...

A 61-year-old man presented with lower leg edema, left-sided parasternal systolic heart murmur, and electrocardiographic abnormalities. Transthoracic echocardiography revealed myocardial hypertrophy and severe obstruction of the outflow tract of the right ventricle (RV) with a gradient of 134 mmHg. Cardiac catheterization confirmed the presence of double chambered right ventricle, with a pressure gradient of 84 mmHg between RV inlet and outlet. Chest computed tomography showed his aortic root enlarged to 55 mm...

25 formalin-fixed hearts of different tortoise species (Testudinidae) underwent gross-anatomical examination. The aim of the study was to illustrate the specific anatomy of the heart of these species in comparison to the data available in the literature. The examined tortoises showed the well-known basic structure of a reptile heart with two atria and a ventricle composed of three interconnected chambers. The right atrium was consistently slightly larger than the left atrium. The atrioventricular (AV-) valves emerged as double-flap valves, whereby the lateral leaflets were only present in a rudimentary form...

We herein describe an adult case of double-chambered right ventricle (DCRV) with symptomatic drug-intolerant paroxysmal atrial fibrillation (PAf). The woman was referred to undergo radiofrequency ablation (RFA), and mapping of the pulmonary veins (PVs) demonstrated that a spontaneous spike potential originating from the left inferior PV (LIPV) induced sustained Af in the second procedure. Accordingly, the LIPV was regarded as the arrhythmogenic PV. Since complete isolation of the PVs, the sinus rhythm has been maintained for at least two years...

Cardiovascular abnormality is the most consistent finding and occur in almost 80 % of all Williams syndrome (WS). Although a number of cardiovascular defects are common to WS, the majority presents in some form of arterial stenosis whereas supravalvular aortic stenosis is the most common one. Here we describe a 12 year old boy with elfin facies, presenting with urinary incontinence and a systolic murmur in right upper parasternal region. Echocardiography showed presence of double chambered right ventricle (DCRV) along with supravalvular aortic stenosis (SVAS) and coronary artery aneurysms, left pulmonary artery stenosis and multiple bladder diverticula in CT abdomen...

BACKGROUND: Patients with small ventricular septal defects (VSDs) are thought to have excellent long-term survival, although complications may not be uncommon. METHODS: We identified all patients aged ≥ 16 years with native isolated VSD between January 2000 and September 2013. Clinical outcomes were retrospectively reviewed. Transthoracic echocardiograms performed within 2 years of last assessment were reviewed for hemodynamic sequelae. RESULTS: Two-hundred-and-thirty-one patients, 100 (43%) male, mean age at last follow-up 34 ± 13 years were studied...
