Double Chambered Left Ventricle

Pei Ma, Shi Gu, Ganga H Karunamuni, Michael W Jenkins, Michiko Watanabe, Andrew M Rollins
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, due to 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...

OBJECTIVE: To use multidetector computed tomography (MDCT) to evaluate the structural changes in the right heart and pulmonary arteries that occur in patients with severe pulmonary hypertension treated by double lung transplantation. MATERIAL AND METHODS: This was a retrospective study of 21 consecutive patients diagnosed with severe pulmonary hypertension who underwent double lung transplantation at our center between 2010 and 2014. We analyzed the last MDCT study done before lung transplantation and the first MDCT study done after lung transplantation...

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...

OBJECTIVE: We describe a repertoire of repair techniques according to type of Ebstein's anomaly to correct tricuspid valve (TV) incompetence, and report long-term ventricular function and functional outcomes. METHODS: Sixty-eight patients (mean age, 26.9 ± 7.3 years) with Ebstein's anomaly (type A, n = 21; type B, n = 23; type C, n = 15; type D, n = 9) underwent correction of TV incompetence under normothermic cardiopulmonary bypass. The atrialized ventricle, TV, and subvalvar apparatus were inspected to analyze the precise morphology and determine which leaflet was the most mobile...

A single ventricle is a rare congenital heart disease that accounts for less than 1% of all congenital heart diseases. A woman was assessed in our obstetric clinic for the first time at the gestational age of 28 weeks and found to have placental bleeding. She also had complex congenital heart disease and atrial fibrillation requiring anticoagulation. Echocardiography revealed double-inlet single ventricle with right and left atrioventricular valves entering into this chamber and levo-transposition of the great arteries...

A 70-year-old woman with symptomatic Mobitz type II atrioventricular block underwent implantation of a dual-chamber pacemaker 11 years ago. The leads were inserted through a percutaneous puncture of the right subclavian vein, using standard techniques. Both leads were passive fixation leads. Due to battery failure and end of life criteria, the pulse generator (PG) had been routinely replaced six years previously. Predischarge pacemaker control revealed normal pacing, sensing thresholds and impedance for both leads...

BACKGROUND: Congenital left ventricular outpouchings (LVOs) are reported under five overlapping and poorly defined terms including left ventricular accessory chamber, left ventricular aneurysm (LVA), left ventricular diverticulum (LVD), double-chambered LV, and accessory left ventricle. Diagnostic criteria are frequently mixed and not mutually exclusive. They convey no information regarding treatment strategy and prognosis. OBJECTIVES: The aim of this systematic review is to provide a clear and inclusive classification, with therapeutic and prognostic implications, for congenital LVOs...

The concept of univentricular heart moved from hearts with only one ventricle connected with atria [double inlet ventricle or absent atrioventricular (AV) connection] to hearts not amenable to biventricular repair, namely hearts with two ventricles unable to sustain separately pulmonary and systemic circulations in sequence. In the latter definition, even hearts with one hypoplastic ventricle are considered "functional" univentricular hearts. They include pulmonary/aortic atresia or severe stenosis with hypoplastic ventricle, and rare conditions like huge intramural cardiac tumors and Ebstein anomaly with extreme atrialization of right ventricular cavity...

Herein, we report an unusual case of right aortic arch with isolation of the left innominate artery in a case of double chamber right ventricle with ventricular septal defect. The blood supply to the innominate artery was by a collateral arising from the descending aorta. The embryological development of this anomaly can be explained by the hypothetical double aortic arch model proposed by Edwards with interruption of the arch at two levels.

Double-chambered left ventricle is a rare congenital disorder in which the left ventricular cavity is subdivided into two cavities by an anomalous septum or muscle band. We describe a case of double-chambered left ventricle, most likely caused by the presence of excessive left ventricular bands, in an asymptomatic cat.

VACTERL association is a non-random association of birth defects of unknown etiology derived from structures of embryonic mesoderm. The common cardiac defects seen with VACTERL association are ventricular septal defects, atrial septal defects, and tetralogy of Fallot. We present a 2-year-old child with VACTERL association in whom we detected double-chambered left ventricle on transthoracic echocardiography.
