Heart ventricles. Medical search

The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.

The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

The hollow, muscular organ that maintains the circulation of the blood.

The number of times the HEART VENTRICLES contract per unit of time, usually per minute.

Four CSF-filled (see CEREBROSPINAL FLUID) cavities within the cerebral hemispheres (LATERAL VENTRICLES), in the midline (THIRD VENTRICLE) and within the PONS and MEDULLA OBLONGATA (FOURTH VENTRICLE).

A narrow cleft inferior to the CORPUS CALLOSUM, within the DIENCEPHALON, between the paired thalami. Its floor is formed by the HYPOTHALAMUS, its anterior wall by the lamina terminalis, and its roof by EPENDYMA. It communicates with the FOURTH VENTRICLE by the CEREBRAL AQUEDUCT, and with the LATERAL VENTRICLES by the interventricular foramina.

An irregularly shaped cavity in the RHOMBENCEPHALON, located between the MEDULLA OBLONGATA; the PONS; and the isthmus in front, and the CEREBELLUM behind. It is continuous with the central canal of the cord below and with the CEREBRAL AQUEDUCT above, and through its lateral and median apertures it communicates with the SUBARACHNOID SPACE.

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Cavity in each of the CEREBRAL HEMISPHERES derived from the cavity of the embryonic NEURAL TUBE. They are separated from each other by the SEPTUM PELLUCIDUM, and each communicates with the THIRD VENTRICLE by the foramen of Monro, through which also the choroid plexuses (CHOROID PLEXUS) of the lateral ventricles become continuous with that of the third ventricle.

Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.

Neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle. Ventricular tumors may be primary (e.g., CHOROID PLEXUS NEOPLASMS and GLIOMA, SUBEPENDYMAL), metastasize from distant organs, or occur as extensions of locally invasive tumors from adjacent brain structures.

Pathological conditions involving the HEART including its structural and functional abnormalities.

The transference of a heart from one human or animal to another.

The heart of the fetus of any viviparous animal. It refers to the heart in the postembryonic period and is differentiated from the embryonic heart (HEART/embryology) only on the basis of time.

The chambers of the heart, to which the BLOOD returns from the circulation.

Contractile activity of the MYOCARDIUM.

Flaps of tissue that prevent regurgitation of BLOOD from the HEART VENTRICLES to the HEART ATRIA or from the PULMONARY ARTERIES or AORTA to the ventricles.

The hemodynamic and electrophysiological action of the HEART VENTRICLES.

The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.

Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.

Ultrasonic recording of the size, motion, and composition of the heart and surrounding tissues. The standard approach is transthoracic.

The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM.

The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)

Examinations used to diagnose and treat heart conditions.

Striated muscle cells found in the heart. They are derived from cardiac myoblasts (MYOBLASTS, CARDIAC).

This structure includes the thin muscular atrial septum between the two HEART ATRIA, and the thick muscular ventricular septum between the two HEART VENTRICLES.

Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.

The innermost layer of the heart, comprised of endothelial cells.

The hemodynamic and electrophysiological action of the right HEART VENTRICLE.

The amount of BLOOD pumped out of the HEART per beat, not to be confused with cardiac output (volume/time). It is calculated as the difference between the end-diastolic volume and the end-systolic volume.

A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).

Phasic right coronary artery blood flow in conscious dogs with normal and elevated right ventricular pressures. (1/10358)

We studied phasic right coronary blood flow in well trained normal dogs and dogs with pulmonic stenosis. We installed electromagnetic flow transducers and pressure tubes under anesthesia to monitor right coronary blood flow, cardiac output, central aortic blood pressure, and right ventribular pressure. In normotensive dogs, systolic flow amplitude equaled early diastolic flow levels. The ratio of systolic to diastolic flow at rest was substantially greater in the right coronary bed (36+/-1.3%) than in the left circumflex bed (13+/-3.6%). Right diastolid flow runoff, including the cove late in diastole, resembled left circumflex runoff. Blood flow to the normotensive right (37+/-1.1 ml/min 100(-1) g) and the left (35+/-1.0 ml/min(-1) g) ventricular myocardium indicated equal perfusion of both cardiac walls. Throttling of systolic flow was related directly to the right ventricular systolic pressure level in the dogs with pulmonic stenosis. Retrograde systolic flow occurred in severe right ventricular hypertension. The late diastolic runoff pattern in dogs with pulmonic stenosis appeared the same as for the normotensive dogs. We obtained systolic to diastolic flow ratios of 1/3 the value of normotensive hearts in high and severe pulmonic hypertension. Electrocardiograms and studies of pathology suggested restricted blood flow to the inner layers of the right myocardium in the dogs with severe and high right ventricular hypertension. Normotensive and hypertensive peak hyperemic flow responses were similar, except for an increased magnitude of diastolic flow, with proportionately less systolic flow in hypertensive states. (+info)

Regulation of chamber-specific gene expression in the developing heart by Irx4. (2/10358)

The vertebrate heart consists of two types of chambers, the atria and the ventricles, which differ in their contractile and electrophysiological properties. Little is known of the molecular mechanisms by which these chambers are specified during embryogenesis. Here a chicken iroquois-related homeobox gene, Irx4, was identified that has a ventricle-restricted expression pattern at all stages of heart development. Irx4 protein was shown to regulate the chamber-specific expression of myosin isoforms by activating the expression of the ventricle myosin heavy chain-1 (VMHC1) and suppressing the expression of the atrial myosin heavy chain-1 (AMHC1) in the ventricles. Thus, Irx4 may play a critical role in establishing chamber-specific gene expression in the developing heart. (+info)

Insulin-like growth factor-1 induces Mdm2 and down-regulates p53, attenuating the myocyte renin-angiotensin system and stretch-mediated apoptosis. (3/10358)

Insulin-like growth factor (IGF)-1 inhibits apoptosis, but its mechanism is unknown. Myocyte stretching activates p53 and p53-dependent genes, leading to the formation of angiotensin II (Ang II) and apoptosis. Therefore, this in vitro system was used to determine whether IGF-1 interfered with p53 function and the local renin-angiotensin system (RAS), decreasing stretch-induced cell death. A single dose of 200 ng/ml IGF-1 at the time of stretching decreased myocyte apoptosis 43% and 61% at 6 and 20 hours. Ang II concentration was reduced 52% at 20 hours. Additionally, p53 DNA binding to angiotensinogen (Aogen), AT1 receptor, and Bax was markedly down-regulated by IGF-1 via the induction of Mdm2 and the formation of Mdm2-p53 complexes. Concurrently, the quantity of p53, Aogen, renin, AT1 receptor, and Bax was reduced in stretched myocytes exposed to IGF-1. Conversely, Bcl-2 and the Bcl-2-to-Bax protein ratio increased. The effects of IGF-1 on cell death, Ang II synthesis, and Bax protein were the consequence of Mdm2-induced down-regulation of p53 function. In conclusion, the anti-apoptotic impact of IGF-1 on stretched myocytes was mediated by its capacity to depress p53 transcriptional activity, which limited Ang II formation and attenuated the susceptibility of myocytes to trigger their endogenous cell death pathway.

Adenoviral gene transfer of the human V2 vasopressin receptor improves contractile force of rat cardiomyocytes. (4/10358)

BACKGROUND: In congestive heart failure, high systemic levels of the hormone arginine vasopressin (AVP) result in vasoconstriction and reduced cardiac contractility. These effects are mediated by the V1 vasopressin receptor (V1R) coupled to phospholipase C beta-isoforms. The V2 vasopressin receptor (V2R), which promotes activation of the Gs/adenylyl cyclase system, is physiologically expressed in the kidney but not in the myocardium. Expression of a recombinant V2R (rV2R) in the myocardium could result in a positive inotropic effect via the endogenous high concentrations of AVP in heart failure. METHODS AND RESULTS: A recombinant adenovirus encoding the human V2R (Ad-V2R) was tested for its ability to modulate the cardiac Gs/adenylyl cyclase system and to potentiate contractile force in rat ventricular cardiomyocytes and in H9c2 cardiomyoblasts. Ad-V2R infection resulted in a virus concentration-dependent expression of the transgene and led to a marked increase in cAMP formation in rV2R-expressing cardiomyocytes after exposure to AVP. Single-cell shortening measurements showed a significant agonist-induced contraction amplitude enhancement, which was blocked by the V2R antagonist, SR 121463A. Pretreatment of Ad-V2R-infected cardiomyocytes with AVP led to desensitization of the rV2R after short-term agonist exposure but did not lead to further loss of receptor function or density after long-term agonist incubation, thus demonstrating resistance of the rV2R to downregulation. CONCLUSIONS: Adenoviral gene transfer of the V2R in cardiomyocytes can modulate the endogenous adenylyl cyclase-signal transduction cascade and can potentiate contraction amplitude in cardiomyocytes. Heterologous expression of cAMP-forming receptors in the myocardium could lead to novel strategies in congestive heart failure by bypassing the desensitized beta-adrenergic receptor signaling.

An inhibitor of p38 mitogen-activated protein kinase protects neonatal cardiac myocytes from ischemia. (5/10358)

Cellular ischemia results in activation of a number of kinases, including p38 mitogen-activated protein kinase (MAPK); however, it is not yet clear whether p38 MAPK activation plays a role in cellular damage or is part of a protective response against ischemia. We have developed a model to study ischemia in cultured neonatal rat cardiac myocytes. In this model, two distinct phases of p38 MAPK activation were observed during ischemia. The first phase began within 10 min and lasted less than 1 h, and the second began after 2 h and lasted throughout the ischemic period. Similar to previous studies using in vivo models, the nonspecific activator of p38 MAPK and c-Jun NH2-terminal kinase, anisomycin, protected cardiac myocytes from ischemic injury, decreasing the release of cytosolic lactate dehydrogenase by approximately 25%. We demonstrated, however, that a selective inhibitor of p38 MAPK, SB 203580, also protected cardiac myocytes against extended ischemia in a dose-dependent manner. The protective effect was seen even when the inhibitor was present during only the second, sustained phase of p38 MAPK activation. We found that ischemia induced apoptosis in neonatal rat cardiac myocytes and that SB 203580 reduced activation of caspase-3, a key event in apoptosis. These results suggest that p38 MAPK induces apoptosis during ischemia in cardiac myocytes and that selective inhibition of p38 MAPK could be developed as a potential therapy for ischemic heart disease.

Taurine modulates I(Kr) but I(Ks) in guinea-pig ventricular cardiomyocytes. (6/10358)

1. Effects of taurine on the delayed rectifier K+ current (I(K)) in isolated guinea-pig ventricular cardiomyocytes were examined at different intracellular Ca2+ concentration ([Ca2+]i), using whole-cell voltage and current clamp techniques. Experiments were performed at 36 degrees C. 2. Addition of taurine (10-20 mM) decreased the action potential duration (APD) at pCa 8, but increased the APD at pCa 6. Taurine (20 mM) enhanced I(K) at 70 mV by 22.4 +/- 3.1% (n = 6, P < 0.01) at pCa 8, whereas taurine inhibited the I(K) by 27.1 +/- 2.7% (n = 6, P < 0.01) at pCa 6. These responses behaved in a concentration-dependent manner. 3. The I(K) is composed of the rapid and slow components (I(Kr) and I(Ks)). When [Ca2+]i was pCa 6, taurine at 20 mM reduced the tail current of I(Kr) at 70 mV by 16.5 +/- 2.7% (n = 5, P < 0.05) and that of I(Ks) at 70 mV by 27.1 +/- 2.8% (n = 6, P < 0.01). In contrast, at pCa 8, the tail currents of I(Kr) and I(Ks) at 70 mV were enhanced by 13.4 +/- 3.2% (n = 7, P < 0.05) and by 22.4 +/- 3.1% (n = 7, P < 0.01), respectively. The voltages of half-maximum activation (V1/2) for I(Kr) and I(Ks) were not modified by taurine. 4. Addition of E-4031 (5 microM) to taurine had a complete blockade of the tail current of I(Kr), but not I(Ks). The remained tail current (I(Ks)) in the presence of E-4031 (5 microM) was not affected by taurine (20 mM), but was blocked by 293B (30 microM). 5. These results indicate that taurine modulates I(Kr) but not I(Ks), depending on [Ca2+]i, resulting in regulation of the APD. (+info)

A comparison of an A1 adenosine receptor agonist (CVT-510) with diltiazem for slowing of AV nodal conduction in guinea-pig. (7/10358)

1. The purpose of this study was to compare the pharmacological properties (i.e. the AV nodal depressant, vasodilator, and inotropic effects) of two AV nodal blocking agents belonging to different drug classes; a novel A1 adenosine receptor (A1 receptor) agonist, N-(3(R)-tetrahydrofuranyl)-6-aminopurine riboside (CVT-510), and the prototypical calcium channel blocker diltiazem. 2. In the atrial-paced isolated heart, CVT-510 was approximately 5 fold more potent to prolong the stimulus-to-His bundle (S-H interval), a measure of slowing AV nodal conduction (EC50 = 41 nM) than to increase coronary conductance (EC50 = 200 nM). At concentrations of CVT-510 (40 nM) and diltiazem (1 microM) that caused equal prolongation of S-H interval (approximately 10 ms), diltiazem, but not CVT-510, significantly reduced left ventricular developed pressure (LVP) and markedly increased coronary conductance. CVT-510 shortened atrial (EC50 = 73 nM) but not the ventricular monophasic action potentials (MAP). 3. In atrial-paced anaesthetized guinea-pigs, intravenous infusions of CVT-510 and diltiazem caused nearly equal prolongations of P-R interval. However, diltiazem, but not CVT-510, significantly reduced mean arterial blood pressure. 4. Both CVT-510 and diltiazem prolonged S-H interval, i.e., slowed AV nodal conduction. However, the A1 receptor-selective agonist CVT-510 did so without causing the negative inotropic, vasodilator, and hypotensive effects associated with diltiazem. Because CVT-510 did not affect the ventricular action potential, it is unlikely that this agonist will have a proarrythmic action in ventricular myocardium. (+info)

Effects of tumour necrosis factor-alpha on left ventricular function in the rat isolated perfused heart: possible mechanisms for a decline in cardiac function. (8/10358)

1. The cardiac depressant actions of TNF were investigated in the isolated perfused rat heart under constant flow (10 ml min(-1)) and constant pressure (70 mmHg) conditions, using a recirculating (50 ml) mode of perfusion. 2. Under constant flow conditions TNF (20 ng ml(-1)) caused an early (< 25 min) decrease in left ventricular developed pressure (LVDP), which was maintained for 90 min (LVDP after 90 min: control vs TNF; 110 +/- 4 vs 82 +/- 10 mmHg, P < 0.01). 3. The depression in cardiac function seen with TNF under constant flow conditions, was blocked by the ceramidase inhibitor N-oleoylethanolamine (NOE), 1 microM, (LVDP after 90 min: TNF vs TNF with NOE; 82 +/- 10 vs 11 +/- 5 mmHg, P < 0.05). 4. In hearts perfused at constant pressure, TNF caused a decrease in coronary flow rate (change in flow 20 min after TNF: control vs TNF; -3.0 +/- 0.9 vs -8.7 +/- 1.2 ml min(-1), P < 0.01). This was paralleled by a negative inotropic effect (change in LVDP 20 min after TNF: control vs TNF; -17 +/- 7 vs -46 +/- 6 mmHg, P < 0.01). The decline in function was more rapid and more severe than that seen under conditions of constant flow. 5. These data indicate that cardiac function can be disrupted by TNF on two levels, firstly via a direct, ceramidase dependant negative inotropic effect, and secondly via an indirect coronary vasoconstriction.

Cerebral ventricles are the cavities within the brain that are filled with cerebrospinal fluid (CSF). They are responsible for producing and circulating CSF, which serves as a cushion and lubricant for the brain and spinal cord, and helps to protect them from injury. The cerebral ventricles are divided into four main parts: the lateral ventricles, the third ventricle, the fourth ventricle, and the cerebellar ventricles. Disorders of the cerebral ventricles can lead to a variety of neurological symptoms, including headaches, seizures, and cognitive impairment.

Heart failure, also known as congestive heart failure, is a medical condition in which the heart is unable to pump enough blood to meet the body's needs. This can lead to a buildup of fluid in the lungs, liver, and other organs, causing symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles. Heart failure can be caused by a variety of factors, including damage to the heart muscle from a heart attack, high blood pressure, or long-term damage from conditions such as diabetes or coronary artery disease. It can also be caused by certain genetic disorders or infections. Treatment for heart failure typically involves medications to improve heart function and reduce fluid buildup, as well as lifestyle changes such as a healthy diet, regular exercise, and avoiding smoking and excessive alcohol consumption. In some cases, surgery or other medical procedures may be necessary to treat the underlying cause of the heart failure or to improve heart function.

Congenital heart defects (CHDs) are structural abnormalities in the heart that are present at birth. These defects can affect the heart's structure, function, or both, and can range from minor to severe. CHDs are the most common type of birth defect and affect approximately 1 in 100 live births. CHDs can occur in any part of the heart, including the valves, arteries, veins, and chambers. Some common types of CHDs include: - Atrial septal defect (ASD): A hole in the wall between the two upper chambers of the heart. - Ventricular septal defect (VSD): A hole in the wall between the two lower chambers of the heart. - Patent ductus arteriosus (PDA): A blood vessel that remains open between the pulmonary artery and the aorta. - Coarctation of the aorta: A narrowing of the aorta, the main artery that carries blood from the heart to the rest of the body. - Tetralogy of Fallot: A combination of four heart defects that affect the flow of blood through the heart. CHDs can cause a range of symptoms, including shortness of breath, fatigue, chest pain, and heart palpitations. Treatment for CHDs depends on the type and severity of the defect, and may include medications, surgery, or other interventions. Early diagnosis and treatment are important for improving outcomes and reducing the risk of complications.

Cerebral ventricle neoplasms, also known as ventricular neoplasms or neoplasms of the cerebral ventricles, are tumors that develop within the ventricles of the brain. The ventricles are fluid-filled cavities that are responsible for producing and circulating cerebrospinal fluid (CSF) throughout the brain and spinal cord. Cerebral ventricle neoplasms can be either benign or malignant, and they can arise from a variety of different cell types. Some common types of ventricular neoplasms include astrocytomas, ependymomas, and choroid plexus papillomas. Symptoms of cerebral ventricle neoplasms can vary depending on the location and size of the tumor, as well as the extent to which it is affecting the surrounding brain tissue. Common symptoms may include headaches, nausea and vomiting, changes in vision or hearing, difficulty with balance or coordination, and seizures. Diagnosis of a cerebral ventricle neoplasm typically involves a combination of imaging studies, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, and a biopsy to confirm the presence of cancer cells. Treatment options for ventricular neoplasms may include surgery, radiation therapy, chemotherapy, or a combination of these approaches, depending on the specific type and stage of the tumor.

Heart diseases refer to a group of medical conditions that affect the heart and blood vessels. These conditions can range from minor to severe and can affect the heart's ability to pump blood effectively, leading to a variety of symptoms and complications. Some common types of heart diseases include: 1. Coronary artery disease: This is the most common type of heart disease, which occurs when the arteries that supply blood to the heart become narrowed or blocked due to the buildup of plaque. 2. Heart failure: This occurs when the heart is unable to pump enough blood to meet the body's needs. 3. Arrhythmias: These are abnormal heart rhythms that can cause the heart to beat too fast, too slow, or irregularly. 4. Valvular heart disease: This occurs when the heart valves become damaged or diseased, leading to problems with blood flow. 5. Congenital heart disease: This refers to heart defects that are present at birth. 6. Inflammatory heart disease: This includes conditions such as pericarditis and myocarditis, which cause inflammation of the heart. 7. Heart infections: These include conditions such as endocarditis and myocarditis, which can cause damage to the heart muscle and valves. Treatment for heart diseases depends on the specific condition and may include medications, lifestyle changes, and in some cases, surgery. Early detection and treatment are important for improving outcomes and reducing the risk of complications.

Heart block is a condition in which the electrical signals that regulate the heartbeat are slowed or blocked as they travel through the heart's conduction system. This can cause the heart to beat too slowly (bradycardia) or irregularly, which can lead to symptoms such as dizziness, fainting, and shortness of breath. There are three main types of heart block: first-degree, second-degree, and third-degree. First-degree heart block is the mildest form and usually does not cause any symptoms. Second-degree heart block is more serious and can cause symptoms, especially if it is caused by an underlying heart condition. Third-degree heart block is the most serious form and can lead to life-threatening complications if not treated promptly. Heart block can be caused by a variety of factors, including damage to the heart muscle, certain medications, and inherited conditions. Treatment options depend on the severity of the heart block and the underlying cause. In some cases, a pacemaker may be necessary to regulate the heartbeat.

Cardiomegaly is a medical condition characterized by an enlarged heart. The term "cardiomegaly" comes from the Greek words "kardia," meaning heart, and "mega," meaning large. Cardiomegaly can be caused by a variety of factors, including hypertension, valvular heart disease, myocardial infarction (heart attack), cardiomyopathy (disease of the heart muscle), and certain genetic disorders. The diagnosis of cardiomegaly is typically made through imaging tests such as echocardiography, chest X-rays, or computed tomography (CT) scans. Cardiomegaly can lead to a variety of complications, including heart failure, arrhythmias, and increased risk of stroke. Treatment depends on the underlying cause of the cardiomegaly and may include medications, lifestyle changes, and in some cases, surgery.

Myocardial ischemia is a medical condition that occurs when the blood flow to the heart muscle is reduced or blocked, leading to a lack of oxygen and nutrients to the heart cells. This can cause chest pain or discomfort, shortness of breath, and other symptoms. Myocardial ischemia is often caused by atherosclerosis, a condition in which plaque builds up in the arteries, narrowing or blocking the flow of blood. It can also be caused by other factors, such as heart valve problems or blood clots. Myocardial ischemia can be a serious condition and requires prompt medical attention to prevent heart attack or other complications.

Likewise in the systolic phase, the left ventricle must contract rapidly and forcibly to pump this blood into the aorta, overcoming the much higher aortic pressure. (wikipedia.org)
In these patients it is important to determine the end-systolic phase independently for the right and left ventricle. (rug.nl)
Systolic pressures are equal in both ventricles and in the aorta. (medscape.com)

In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta. (wikipedia.org)
The left ventricle receives oxygenated blood from the left atrium via the mitral valve and pumps it through the aorta via the aortic valve, into the systemic circulation. (wikipedia.org)
For example, some researchers require that the aorta and the pulmonary artery arise entirely from the right ventricle. (medscape.com)
Double outlet right ventricle, with a large variability in anatomy, represents a continuum of congenital heart defects (CHDs) that includes ventricular septal defect (VSD) with significant override of the aorta, origin of both great arteries from the right ventricle, and transposition of the great arteries with pulmonary override of the VSD. (medscape.com)
The resulting physiology is similar to tetralogy of Fallot , in which the aorta completely overrides the right ventricle. (medscape.com)
In double outlet right ventricle, both the aorta and pulmonary valve connect to the right ventricle. (msdmanuals.com)
Normally the pulmonary valve connects to the right ventricle, and the aorta connects to the left ventricle. (msdmanuals.com)

Overview of Heart Defects About one in 100 babies is born with a heart defect. (msdmanuals.com)
Atrial and Ventricular Septal Defects Atrial and ventricular septal defects are holes in the walls (septa) that separate the heart into the left and right sides. (msdmanuals.com)

A ventricular septal defect (VSD) is a common kind of heart defect. (drugs.com)
A ventricular septal defect is virtually always present and provides the only outlet of blood flow from the left ventricle. (msdmanuals.com)

Both the atria and ventricles have values that open and close in a synchronized way that helps to control blood flow throughout the body. (medicalnewstoday.com)

The physiological load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure generated by the atria to fill the ventricles. (wikipedia.org)
Further, the left ventricle has thicker walls than the right because it needs to pump blood to most of the body while the right ventricle fills only the lungs. (wikipedia.org)
BNP testing can tell if your child has a problem with the heart or lungs. (uhhospitals.org)
As a result, the heart muscle's ability to pump blood is reduced, which can lead to irregular heartbeats, the backup of blood into the lungs or rest of the body, and heart failure. (cdc.gov)
Smoke can also harm his or her lungs and heart. (drugs.com)
If too much blood flows through the pulmonary artery to the lungs, heart failure may develop. (msdmanuals.com)
If too much blood flows to the lungs, medications are needed to improve heart function and treat the resulting heart failure. (msdmanuals.com)

Ablation is a catheterization procedure that uses heat or cold to repair the heart tissue causing the arrhythmia. (chla.org)

Dilated endocardial fibroelastosis is characterized by a markedly enlarged globular heart, mainly involving the left ventricle (LV) and left atrium (LA). The LV endocardium is opaque, glistening, milky white, and diffusely thickened to about 1-2 mm. (medscape.com)

The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle. (wikipedia.org)
The right ventricle is triangular in shape and extends from the tricuspid valve in the right atrium to near the apex of the heart. (wikipedia.org)
Bigeminy can occur as a result of a heartbeat irregularity involving either the atrium or ventricles. (medicalnewstoday.com)
Bigeminy involving a heartbeat irregularity in the atrium is due to premature atrial contractions (PACs), while bigeminy involving the ventricles is due to premature ventricular contractions (PVCs). (medicalnewstoday.com)
Endocardial thickening extends to the LA, right ventricle, and right atrium. (medscape.com)

In some cases, atrial fibrillation can be corrected with medication or by administering a shock to a sedated patient's heart. (mayoclinic.org)
The AI system identified associations between pathology in the retina and changes in the patient's heart. (leeds.ac.uk)
Currently, details about the size and pumping efficiency of a patient's left ventricle can only be determined if they have diagnostic tests such as echocardiography or magnetic resonance imaging of the heart. (leeds.ac.uk)

However, in the absence of pulmonary obstruction or stenosis, patients with double outlet right ventricle and subpulmonary VSD have physiology similar to transposition of the great arteries and VSD. (medscape.com)

Atorvastatin is also used to reduce the risk of heart attack for people with high blood pressure who have at least 3 additional risk factors for heart disease but are not experiencing symptoms associated with heart disease. (medbroadcast.com)

In adulthood many patients with congenital heart disease develop complications of the right ventricle. (rug.nl)
Measured blood volumes may significantly deviate from the true blood volume in patients with congenital heart disease. (rug.nl)
These are also considered of pivotal importance for groups which care for patients with congenital heart disease as well as for policymakers. (who.int)

Morphometric light microscopic analysis of cardiomyocytes of the left ventricle revealed an increase of the area of cell cross sections, whereas the number of capillaries remained the same in the normal heart, which was suggested to be a weak adaptive response. (nih.gov)
