Regulation of chamber-specific gene expression in the developing heart by Irx4. (1/4530)

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)

Transcatheter closure of patent foramen ovale using the Amplatzer septal occluder to prevent recurrence of neurological decompression illness in divers. (2/4530)

OBJECTIVE: Large flap valve patent foramens may cause paradoxical thromboembolism and neurological decompression illness in divers. The ability of a self expanding Nitinol wire mesh device (Amplatzer septal occluder) to produce complete closure of the patent foramen ovale was assessed. PATIENTS: Seven adults, aged 18-60 years, who had experienced neurological decompression illness related to diving. Six appeared to have a normal atrial septum on transthoracic echocardiography, while one was found to have an aneurysm of the interatrial septum. METHODS: Right atrial angiography was performed to delineate the morphology of the right to left shunt. The defects were sized bidirectionally with a precalibrated balloon filled with dilute contrast. The largest balloon diameter that could be repeatedly passed across the septum was used to select the occlusion device diameter. Devices were introduced through 7 F long sheaths. All patients underwent transthoracic contrast echocardiography one month after the implant. RESULTS: Device placement was successful in all patients. Device sizes ranged from 9-14 mm. The patient with an aneurysm of the interatrial septum had three defects, which were closed with two devices. Right atrial angiography showed complete immediate closure in all patients. Median (range) fluoroscopy time was 13.7 (6-35) minutes. Follow up contrast echocardiography showed no right to left shunting in six of seven patients and the passage of a few bubbles in one patient. All patients have been allowed to return to diving. CONCLUSION: The Amplatzer septal occluder can close the large flap valve patent foramen ovale in divers who have experienced neurological decompression illness. Interatrial septal aneurysms with multiple defects may require more than one device.  (+info)

Pregnancy after atrial repair for transposition of the great arteries. (3/4530)

OBJECTIVE: To investigate the risk of pregnancy in patients with transposition of the great arteries (TGA) who have undergone atrial repair. DESIGN: Retrospective analysis (1962-94) of 342 TGA patients who underwent atrial repair. Of 231 known late survivors, 48 were women over 18 years old who were interviewed about possible reproductive plans and previous pregnancies. As a control, comparison was made with data of 57 500 women (mean age 26 years) obtained from the Swiss Statistical Bank in Bern. RESULTS: Mean follow up was 13.7 years; 66% remained asymptomatic, 29% had mild to moderate cardiac symptoms, and 5% suffered from severe cardiac symptoms (New York Heart Association grade III-IV). Thirty six of the 48 women wished to bear children and, to date, there have been 10 live births, two spontaneous first trimester abortions, and one induced abortion at 16 weeks. During pregnancy there was one case of cardiac deterioration and two cases of pneumonia. There was no evidence of congenital heart disease in the children. CONCLUSIONS: In this relatively small series the completion of pregnancy in women with TGA who had undergone atrial repair and who had normal functional cardiac status was uncomplicated  (+info)

Freeze-fracture studies of frog atrial fibres. (4/4530)

The freeze-fracturing technique was used to characterize the junctional devices involved in the electrical coupling of frog atrial fibres. These fibres are connected by a type of junction which can be interpreted as a morphological variant of the "gap junction" or "nexus". The most characteristic features are rows of 9-nm junctional particles forming single or anastomosed circular profiles on the inner membrane face, and corresponding pits on the outer membrane face. Very seldom aggregates consisting of few geometrically disposed 9-nm particles are found. The significance of the junctional structures in the atrial fibres is discussed, with respect to present knowledge about junctional features of gap junctions in various tissues, including embryonic ones.  (+info)

A comparison of an A1 adenosine receptor agonist (CVT-510) with diltiazem for slowing of AV nodal conduction in guinea-pig. (5/4530)

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)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (6/4530)

PURPOSE: Central venous obstruction is a common problem in patients with chronic renal failure who undergo maintenance hemodialysis. We studied the use of right atrial bypass grafting in nine cases of central venous obstruction associated with upper extremity venous hypertension. To better understand the options for managing this condition, we discuss the roles of surgery and percutaneous transluminal angioplasty with stent placement. METHODS: All patients had previously undergone placement of bilateral temporary subclavian vein dialysis catheters. Severe arm swelling, graft thrombosis, or graft malfunction developed because of central venous stenosis or obstruction in the absence of alternative access sites. A large-diameter (10 to 16 mm) externally reinforced polytetrafluoroethylene (GoreTex) graft was used to bypass the obstructed vein and was anastomosed to the right atrial appendage. This technique was used to bypass six lesions in the subclavian vein, two lesions at the innominate vein/superior vena caval junction, and one lesion in the distal axillary vein. RESULTS: All patients except one had significant resolution of symptoms without operative mortality. Bypass grafts remained patent, allowing the arteriovenous grafts to provide functional access for 1.5 to 52 months (mean, 15.4 months) after surgery. CONCLUSION: Because no mortality directly resulted from the procedure and the morbidity rate was acceptable, this bypass grafting technique was adequate in maintaining the dialysis access needed by these patients. Because of the magnitude of the procedure, we recommend it only for the occasional patient in whom all other access sites are exhausted and in whom percutaneous dilation and/or stenting has failed.  (+info)

Alterations of cross-bridge kinetics in human atrial and ventricular myocardium. (7/4530)

CONDENSED ABSTRACT: We analyzed actomyosin cross-bridge kinetics in human atrial and ventricular muscle strip preparations by using sinusoidal length changes from 0.1 to 60 Hz. The minimum stiffness frequency was higher in atrial than in ventricular human myocardium and lower in failing than in non-failing left ventricular human myocardium. beta-Adrenergic stimulation increased the minimum stiffness frequency by 18 +/- 3% (p < 0.05). Cross-bridge kinetics are temperature-dependent, with a Q10 of at least 2.7. BACKGROUND: Dynamic stiffness measurements have revealed acute and chronic alterations of actomyosin cross-bridge kinetics in cardiac muscles of a variety of different animal species. We studied dynamic stiffness in right atrial and left ventricular preparations of non-failing and failing human hearts and tested the influence of the temperature and beta-adrenergic stimulation on cross-bridge kinetics. METHODS AND RESULTS: Muscle strips were prepared from right atria and left ventricles from human non-failing and failing hearts. After withdrawal of calcium, steady contracture tension was induced by the addition of 1.5 mM barium chloride. Sinusoidal length oscillations of 1% muscle length were applied, with a frequency spectrum of between 0.1 and 60 Hz. Dynamic stiffness was calculated from the length change and the corresponding force response amplitude. The specific minimum stiffness frequency, which indicates the interaction between cross-bridge recruitment and cross-bridge cycling dynamics, was analyzed for each condition: (1) The minimum stiffness frequency was 0.78 +/- 0.04 Hz in left ventricular myocardium and 2.80 +/- 0.31 Hz in right atrial myocardium (p < 0.01) at 27 degrees C. (2) The minimum stiffness frequency was 41% higher in non-failing compared to failing left ventricular human myocardium. (3) Over a wide range of experimental temperatures, the minimum stiffness frequency changed, with a Q10 of at least 2.7. (4) beta-Adrenergic stimulation significantly (p < 0.05) increased the minimum stiffness to 18 +/- 3% higher frequencies and significantly (p < 0.05) lowered contracture tension by 7 +/- 1%. CONCLUSIONS: The contractility of human heart muscle is not only regulated by excitation-contraction coupling but also by modulation of intrinsic properties of the actomyosin system. Acute and chronic alterations of cross-bridge kinetics have been demonstrated, which play a significant role in the physiology and pathophysiology of the human heart.  (+info)

Transcatheter occlusion of a post-Fontan residual hepatic vein to pulmonary venous atrium communication using the Amplatzer septal occluder. (8/4530)

A residual hepatic vein to left atrial communication may result in progressive cyanosis after the Fontan procedure. This problem has usually been treated surgically by ligation or re-inclusion of the residual hepatic vein in the Fontan circulation. Previous attempts at transcatheter closure of such veins have been unsuccessful. An Amplatzer septal occluder was successfully used for transcatheter closure of a post-Fontan hepatic vein to pulmonary venous atrium fistula in an 8 year old boy.  (+info)

Introduction: The development of improved diagnosis, management, and treatment strategies for human atrial fibrillation (AF) is a significant and important challenge in order to improve quality of life for millions and reduce the substantial social-economic costs of the condition. As a complex condition demonstrating high variability and relation to other cardiac conditions, the study of AF requires approaches from multiple disciplines including single-cell experimental electrophysiology and computational modeling. Models of human atrial cells are less well parameterized than those of the human ventricle or other mammal species, largely due to the inherent challenges in patch clamping human atrial cells. Such challenges include, frequently, unphysiologically depolarized resting potentials and thus injection of a compensatory hyperpolarizing current, as well as detecting certain ion currents which may be disrupted by the cell isolation process. The aim of this study was to develop a laboratory specific

Courtemanche, Ramirez, Nattel, 1998 - Physiome Model RepositoryCourtemanche, Ramirez, Nattel, 1998 - Physiome Model Repository
The ionic mechanisms underlying many important properties of the human atrial action potential are poorly understood. Using specific formulations of the K+, Na+ and Ca2+ currents based on experimental data recorded from human atrial myocytes, along with representations of pump, exchange and background currents, Marc Courtemanche, Rafael J. Ramirez and Stanley Nattel developed a mathematical model of the action potential (see the figure below). This mathematical model builds mostly on the classical work of Luo and Rudy (see The Luo-Rudy Ventricular Model II (dynamic), 1994). Courtemanche et al effectively develop a working model of the human atrial action potential from the Luo-Rudy model which is based on guinea pig ventricular cells. Their primary goal was to develop a useful model of the action potential from which they could gain insights into experimental observations made on human atrial cells and tissues and make predictions regarding the behaviour of these cells under previously untested ...

Although isolated mitochondria experiments showed that aging-related dysfunction of mitochondrial respiration may prevent APC, isoflurane could still protect isolated intact aged human cardiomyocytes from stress-induced cell death. Indeed, pretreatment of MA myocytes with isoflurane improved cell survival during acute oxidative stress, whereas this effect was much less pronounced in OA myocytes, suggesting that aging-related changes in mitochondrial function could affect viability of MA and OA myocytes. The involvement of another potential effector of APC, the sarcKATPchannel,14 in human cardiomyocyte protection was tested using HMR-1098, the sarcKATPchannel blocker. HMR-1098 attenuated the protection by isoflurane, suggesting that in adult human atrial myocytes, protection from stress is mediated partly via sarcKATPchannel. The properties of single sarcKATPchannels from adult human right atrial myocytes, amplitude of unitary KATPcurrent, slope conductance at negative membrane potentials, and ...

A heartbeat is one cycle in which your hearts ventricles relax (diastole) and squeeze (systole) to pump blood. This cycle includes the opening and closing of the valves of your heart.. When your hearts ventricles relax, blood flows from the atria to the ventricles. Your hearts atria squeeze and pump blood into the ventricles. The atria then relax. Your hearts ventricles then squeeze, pumping blood out of your heart.. ...

Stage B1 Chronic Degenerative Valve Disease (CDVD). CDVD is a condition in which the valves regulating blood flow through the small chambers of the heart (atria) and the larger pumping chambers of the heart (ventricles) undergo degenerative changes and no longer create a tight seal when the ventricles contract. These changes allow blood to regurgitate, or leak back into the atria (see image to the right). The blood flowing across the leak creates the murmur that we hear. Some dogs have a leak only across the mitral valve on the left side of the heart, and some dogs have leaks across multiple heart valves.. Stage B1 refers to a patient that has developed a leak across its valve, but the condition has not yet caused enlargement, or remodeling of the heart. Stage B1 is therefore considered an early and mild form … Read More ». ...

Piezo1 Channels Contribute to the Regulation of Human Atrial Fibroblast Mechanical Properties and Matrix Stiffness Sensing. -...
The mechanical environment of cardiac cells changes continuously and undergoes major alterations during diseases. Most cardiac diseases, including atrial fibrillation, are accompanied by fibrosis which can impair both electrical and mechanical function of the heart. A key characteristic of fibrotic tissue is excessive accumulation of extracellular matrix, leading to increased tissue stiffness. Cells are known to respond to changes in their mechanical environment, but the molecular mechanisms underlying this ability are incompletely understood. We used cell culture systems and hydrogels with tunable stiffness, combined with advanced biophysical and imaging techniques, to elucidate the roles of the stretch-activated channel Piezo1 in human atrial fibroblast mechano-sensing. Changing the expression level of Piezo1 revealed that this mechano-sensor contributes to the organization of the cytoskeleton, affecting mechanical properties of human embryonic kidney cells and human atrial fibroblasts.

Abstract 1847: Left Atrial Volume Index Predicts Heart Failure and Mortality: the Heart and Soul Study | CirculationAbstract 1847: Left Atrial Volume Index Predicts Heart Failure and Mortality: the Heart and Soul Study | Circulation
Background: We sought to establish the predictive ability of left atrial (LA) volume index for stroke, heart failure (HF) hospitalization, and mortality, and to define its value in relation to left ventricular ejection fraction (LVEF) among outpatients with coronary artery disease.. Methods: We measured LA volume in 936 adults enrolled in the Heart and Soul Study without atrial fibrillation, flutter, or significant mitral valve disease. Outcomes for HF, stroke, and mortality were determined by blinded adjudication. Logistic regression was used to calculate odds ratios (OR) adjusted for age, sex, body mass index, race, systolic and diastolic blood pressure, past medical history, alcohol consumption, smoking, diastolic dysfunction, and LVEF.. Results: Mean LA volume index was 33 ± 11 ml/m2; mean LVEF was 62 ± 9.7%. There were 77 HF hospitalizations, 21 strokes, and 117 deaths at 3.5 years follow-up. By c-statistics, the unadjusted discriminative ability for LA volume index was 0.68 for HF, 0.60 ...

We evaluated the relationship between susceptibility to arrhythmias caused by right atrial (RA) enlargement and alterations in transmembrane potentials and ultrastructure. RA enlargement was produced in eight dogs (TI) by excising the septal cusp of the tricuspid valve through a right atriotomy and constricting the pulmonary artery. This procedure resulted in RA dilation and hypertrophy. Four sham-operated dogs (S) also were studied. Neither TI nor S dogs developed spontaneous atrial arrhythmias. Atrial overdrive (OD) and premature stimulation (PS) were used to initiate and terminate arrhythmias. At 2 weeks and for 20 to 30 weeks after surgical preparation, TI dogs were more susceptible to arrhythmias than S dogs. The duration of arrhythmias exceeded 10 minutes more often in TI dogs than in S dogs. Sixty-one percent of all arrhythmias in the TI dogs had rates of 320-450 impulses/min, and electrogram and ECG characteristics of atrial flutter (type II rhythm), whereas no S dogs developed rhythms ...

Early changes in atrial conduction times in hypertensive patients with elevated pulse pressure
Introduction. Hypertension plays a significant role in the etiology of various cardiovascular diseases. Pulse pressure (PP), defined as the difference between systolic blood pressure (SBP) and diastolic blood pressure (DBP), has a strong and independent association with cardiovascular morbidity and mortality.1. Atrial fibrillation (AF) is the most common sustained arrhythmia, for which the classical risk factors are age, diabetes, obesity, hypertension, left ventricular hypertrophy, coronary artery disease, heart failure and valvular disease.2 Previous studies have indicated that both high blood pressure (BP)3 and elevated PP independently predict development of AF.4 Additionally, increased PP is associated with left atrial (LA) enlargement, which is another known risk factor for AF.5 Although pathophysiologically it has been proposed that increased arterial stiffness can lead to increased left ventricular load by elevating PP, it has been determined that PP elevation is a more important risk ...

The heart is made up of four different blood-filled areas, and each of these areas is called a chamber. There are two chambers on each side of the heart. One chamber is on the top and one chamber is on the bottom. The two chambers on top are called the atria (say: AY-tree-uh). If youre talking only about one, call it an atrium. The atria are the chambers that fill with the blood returning to the heart from the body and lungs. The heart has a left atrium and a right atrium.. The two chambers on the bottom are called the ventricles (say: VEN-trih-kulz). The heart has a left ventricle and a right ventricle. Their job is to squirt out the blood to the body and lungs. Running down the middle of the heart is a thick wall of muscle called the septum (say: SEP-tum). The septums job is to separate the left side and the right side of the heart.. The atria and ventricles work as a team - the atria fill with blood, then dump it into the ventricles. The ventricles then squeeze, pumping blood out of the ...

Three dimensional flow in the human left atrium | HeartThree dimensional flow in the human left atrium | Heart
These flow visualisations in the normal human left atrium show that the right and left pulmonary venous inflows behave very differently through the cardiac cycle. The comparatively longer flow pathways of the left lower pulmonary venous inflow appear paradoxical, given that the vein enters in close proximity to the mitral annulus. Instead of first in, first out transit, the left sided inflows are incorporated and recirculate in vortices before finally moving into the left ventricle. The systolic and diastolic vortices result from the interaction of the disparate right and left pulmonary venous inflows with the atrial walls and with each other during the phases of the cardiac cycle when outflow from the atrium diminishes or stops. The residual atrial volume present in the chamber at the onset of those phases is entrained by the inflow and incorporated into the vortex, thereby avoiding complete deceleration. Inflow from the right pulmonary veins follows the vortex at its periphery, constrained ...

LA dissection is a rare complication that occurs predominantly after mitral valve (MV) repair/replacement and occasionally after blunt cardiac trauma, acute myocardial infarction, prosthetic endocarditis, and aortic valve surgery.1-3 The dissection usually originates from the posterior mitral annulus to involve the posterior LA wall; it rarely originates from the anterior mitral annulus to involve the IAS.4 The dissection creates a large expanding cavity between the LA endocardium and the myocardium. In the acute setting, rapid expansion of this dissection cavity may encroach onto the adjacent structures and lead to a decrease in the size of the true LA cavity and obstruction of the LV inlet, pulmonary veins, or even rupture into the true LA cavity, RA, or pericardial cavity.1-4 In our case, the large LA posterior dissection cavity compressed the anterior, true LA cavity and encroached on the mitral prosthesis to cause obstruction of the LV inlet. It communicated with the LV via a small mitral ...

Atrial fibrillation (AF or AFib) is the most common type of heart arrhythmia. It occurs when the atria contract in a fast and erratic manner, making the muscle look like it is quivering. The atrias job is to push blood into the ventricles before they contract. If the atria are beating faster than the ventricles, the ventricles can not completely fill with blood. This can decrease the amount of blood available to push out to the body. Some people have AF without any symptoms. In those that have them, AF can cause palpitations, shortness of breath, lightheadedness, or cognitive impairment. If you have these symptoms, talk to your doctor. People with AF also have an increased risk of stroke or heart attack. Irregular contractions of the atria can cause blood to pool in the atria, which can lead to blood clots. These clots can travel to the brain and cause a stroke. The extra stress on the heart because of poor blood flow from the atria to the ventricle can also eventually lead to heart failure. ...

The pericardium, myocardium and endocardium are the three tissues of the heart from the outside to the inside. The endocardium is the deep tissue in contact with the blood of the cavities of the two Atria and two ventricles;. The ventricles and Atria are the two pairs of Chambers of the heart. The left atrium receives the blood oxygenated through the lungs, it sends it to the left ventricle that extrudes it to all cells in the body via the aorta. The less oxygenated blood returns to the heart by the vena cava at the level of the right atrium. The blood is sent to the right ventricle and the pulmonary artery that sends the blood carry oxygen in the lungs..

Im just going to link you to another post here, which I believe answers the same question. Its because the facilitation of the transient outward current if much more prominent in epicardial regions than in endocardial regions.. And the following citation, Transient outward potassium current, Ito, phenotypes in the mammalian left ventricle: underlying molecular, cellular and biophysical mechanisms, provides some mechanistic insight.. To answer the rest of the question:. So in an ECG you have leads that record whether a charge is moving toward, or away from the lead. These net charges are reflected on the ECG as either positive or negative deflections. You have a signal from the sinoatrial node that causes a depolarization in the right atrium, then the left atrium (biphasic p wave). In each case, however, we see the positive p wave because in this depolarization the net charge is moving toward the electrodes. Studies on atrial repolarization note that yes, the atrial repolarization is ...

Cardiovascular System Module 4: Cardiac Muscle and Electrical Activity
A normal ECG tracing is presented in [link]. Each component, segment, and interval is labeled and corresponds to important electrical events, such as the action potential. demonstrating the relationship between these events and contraction in the heart.. The Action PotentialThe heartbeat is initiated by an electrical stimulus known as an action potential. When the heart receives a signal from the action potential the heart muscle cells depolarize (contract). When this signal fades, the muscle cells will repolarize (relax).. There are five prominent points on the ECG: the P wave, the QRS complex, and the T wave. The small P wave represents the depolarization (contraction) of the atria. The atria begin contracting approximately 25 ms after the start of the P wave. The large QRS complex represents the depolarization (contraction) of the ventricles, which requires a much stronger electrical signal because of the larger size of the ventricular cardiac muscle. During the QRS complex the atria are ...

We sought to determine the diagnostic accuracy of vertebral left atrial size (VLAS), vertebral heart size (VHS), and radiologists assessment for predicting left atrial enlargement (radLAE) in a large population of dogs with and without echocardiographic left atrial enlargement (echoLAE). Dogs that had an echocardiogram and thoracic radiographs performed within 24-hours were consecutively enrolled provided they did not have pericardial effusion or a cardiac mass. EchoLAE was defined by a left atrium to aortic ratio acquired from short-axis (LA/AoSx) and long-axis (LA/AoLx) >1.68 and >2.54, respectively. Radiographic assessments were blinded to echocardiographic assessments and vice versa. Cutoffs for VLAS and VHS were generated using receiver operating characteristic analyses.

Atrial fibrillation (AF) is already the most commonly occurring arrhythmia. Catheter pulmonary vein ablation has emerged as a treatment that is able to make the arrhythmia disappear; nevertheless, recurrence to arrhythmia is very frequent. In this study, it is proposed to perform an analysis of the electrical signals recorded from bipolar catheters at three locations, pulmonary veins and the right and left atria, before to and during the ablation procedure. Principal Component Analysis (PCA) was applied to reduce data dimension and Granger causality and divergence techniques were applied to analyse connectivity along the atria, in three main regions: pulmonary veins, left atrium (LA) and right atrium (RA). The results showed that, before the procedure, patients with recurrence in the arrhythmia had greater connectivity between atrial areas. Moreover, during the ablation procedure, in patients with recurrence in the arrhythmial both atria were more connected than in patients that maintained sinus rhythms

p,Fibroblasts play a major role in heart physiology. They are at the origin of the extracellular matrix renewal and production of various paracrine and autocrine factors. In pathological conditions, fibroblasts proliferate, migrate and differentiate into myofibroblasts leading to cardiac fibrosis. This differentiated status is associated with changes in expression profile leading to neo-expression of proteins such as ionic channels. The present study investigates further electrophysiological changes associated with fibroblast differentiation focusing on the activity of voltage-gated sodium channels in human atrial fibroblasts and myofibroblasts. Using the patch clamp technique we show that human atrial myofibroblasts display a fast inward voltage gated sodium current with a density of 13.28 ± 2.88 pA pF(-1) whereas no current was detectable in non-differentiated fibroblasts. Quantitative RT-PCR reveals a large amount of transcripts encoding the Na(v)1.5 α-subunit with a fourfold increased ...

Mammalian Heart | Biology I
In humans, the heart is about the size of a clenched fist, and it is divided into four chambers: two atria and two ventricles. There is one atrium and one ventricle on the right side and one atrium and one ventricle on the left side. The atria are the chambers that receive blood, and the ventricles are the chambers that pump blood. The right atrium receives deoxygenated blood from the superior vena cava, which drains blood from the jugular vein that comes from the brain and from the veins that come from the arms, as well as from the inferior vena cava which drains blood from the veins that come from the lower organs and the legs.. In addition, the right atrium receives blood from the coronary sinus which drains deoxygenated blood from the heart itself. This deoxygenated blood then passes to the right ventricle through the atrioventricular valve or the tricuspid valve, a flap of connective tissue that opens in only one direction to prevent the backflow of blood. The valve separating the chambers ...

Role of LA Shape in Predicting Embolic Cerebrovascular Events in Mitral Stenosis | JACC: Cardiovascular ImagingRole of LA Shape in Predicting Embolic Cerebrovascular Events in Mitral Stenosis | JACC: Cardiovascular Imaging
In patients with MS, several studies have demonstrated that LA enlargement is a marker of increased thromboembolic risk (4,6,7,9,11,25,26). However, the great majority of studies considered LA size or volume as an indicator of risk. This study aimed to look specifically at LA shape and not just LAVs and LA function in predicting stroke. As LA dilation may not occur in a uniform fashion, LA shape might be a better measure of the pattern of LA remodeling and a better predictor of embolic risk than absolute LAV.. The results of this study show that the atrial shape adds incremental value in predicting embolic events. Additionally, in agreement with a recently published study (27), we found that LA reservoir function was also associated with an increased risk for ECE. Although the LA has 3 major roles that affect LV filling, its reservoir function represents the most important component of the LA function in MS. LA contractile force cannot overcome the mechanical obstruction across the valve and ...

Systole - Simple English Wikipedia, the free encyclopediaSystole - Simple English Wikipedia, the free encyclopedia
Above the ventricles are smaller chambers (sections) of the heart called atria. They contract (squeeze) during the last part of diastole, and send blood down to the larger, lower ventricles. The atria have valves that close after this so blood cannot flow backward into the atria. When the ventricles are filled and the valves to the atria are closed, the ventricles contract. So, the atria and ventricles contract in sequence. The left and right atria feed blood into the ventricles. Then, the left and right ventricles contract. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the rest of the body. This is why we have a pulse. ...

This is a fascinating case, Dr. Smith, and your explication of the essential features is as usual brilliant. Thanks. The patient does seem to also have left atrial enlargement, probably a result of mitral valve disease (stenotic, severely regurgitant, or mixed); this is evidenced by p mitrale - seen in all the limb and augmented limb leads - and the biphasic and terminal negative p wave in V1. There is no evidence of AF in this ECG. Interestingly the PR interval appears a touch short to my eye in some of the leads, especially the lateral precordials. Is that a delta wave in V2? I wonder if the LA enlargement was related to the STEMI. Did he have any visible thrombi in the LA? ReplyDelete ...

Sequence variations of NKX2-5 and HAND1 genes in patients with atrial isomerism | AVESİS
Objective: Atrial isomerism is a congenital disorder, which is characterized by lateralization defects in normally asymmetrical developing organs like the heart. Atrial isomerism is supposed to be caused by molecular defects during early development. The NKX2-5 is a cardiac specific transcription factor, which initiates and regulates downstream transcriptional cascades of cardiogenesis. The HAND1 is another transcription factor expressed in the heart, and it is characterized by an asymmetrical pattern of expression. In this study, we aimed to test whether mutations in NKX2-5 and HAND1 genes play a role in the etiology of atrial isomerism. ...

Atrial Fibrillation 101…
What do I mean when I say, rapidly conducting AF?. Explaining AF in a short blog is impossible. Massively thick books have been written, and week long symposium are routinely given on AF . That said, here is my best impression of Sal Khan, who can explain nearly anything in a 10 min video.. When in AF, the atria are beating (quivering) at 300-500 beats per min. The atria do not pump blood to the body; the ventricle accomplishes this. Ventricular rate (pulse rate) is determined by how fast the AV node conducts the AF impulses from north to south. The AV node acts as a road between the atria and ventricle. It has a certain refractory period which means it can conduct electrical impulses only so fast. The AV nodes speed of conduction varies greatly amongst individuals, and thus, so does the ventricular rate during AF. The inter-person variability of AV conduction is probably in great part genetically determined, whereas the intra-person variability is related to adrenaline levels. The AV node is ...

E/A ratio - WikipediaE/A ratio - Wikipedia
The E/A ratio is a marker of the function of the left ventricle of the heart. It represents the ratio of peak velocity flow in early diastole (the E wave) to peak velocity flow in late diastole caused by atrial contraction (the A wave). It is calculated using Doppler echocardiography, an ultrasound-based cardiac imaging modality. Abnormalities in the E/A ratio suggest that the left ventricle, which pumps blood into the circulation, cannot fill with blood properly in the period between contractions. This phenomenon is referred to as diastolic dysfunction and can eventually lead to the symptoms of heart failure. The heart is a biological pump designed to move blood through the brain and body. It has four chambers: two upper chambers, the atria (single:atrium), and two lower chambers (the ventricles). Anatomically, the atria sit more posterior to the ventricles, but for ease of understanding, are often drawn above them. The atria are separated from the ventricles beneath by the ...

February | 2016 | Dr. Ben-Zur, Encino, California
Patient is in what is known as atrial fibrillation, or afib.. Atrial fibrillation is caused by the rapid, disorganized electrical signals that cause the atria to fibrillate, or, contract fast and irregularly. Rather than a signal coming from that of the SA node, the signal comes from the left atrium at sites of the pulmonary veins. This is a problem because the ventricles do not contract as fast as the atria do and this causes decreased blood flow into the ventricles and causes decreased cardiac output systemically. Patients with afib, due to the rapid rate at which the atrium contracts, tend to have blood pool in their atria. This is a dire problem because the patient becomes susceptible to clots which in turn can lead to a stroke.. There are several types of afib:. Paroxysmal: faulty signal types start and stop on their own. Typically last less than one week but usually resolve more so in 24-48 hours.. Persistent: Abnormal rhythm lasts more than a week but eventually stops on its own or with ...

Atrial fibrillation: effects beyond the atrium? - Oxford Cardiovascular Science
Atrial fibrillation (AF) is the most common sustained clinical arrhythmia and is associated with significant morbidity, mostly secondary to heart failure and stroke, and an estimated two-fold increase in premature death. Efforts to increase our understanding of AF and its complications have focused on unravelling the mechanisms of electrical and structural remodelling of the atrial myocardium. Yet, it is increasingly recognized that AF is more than an atrial disease, being associated with systemic inflammation, endothelial dysfunction, and adverse effects on the structure and function of the left ventricular myocardium that may be prognostically important. Here, we review the molecular and in vivo evidence that underpins current knowledge regarding the effects of human or experimental AF on the ventricular myocardium. Potential mechanisms are explored including diffuse ventricular fibrosis, focal myocardial scarring, and impaired myocardial perfusion and perfusion reserve. The complex relationship

JCI - Atrial fibrillation risk loci interact to modulate Ca2+-dependent atrial rhythm homeostasisJCI - Atrial fibrillation risk loci interact to modulate Ca2+-dependent atrial rhythm homeostasis
Atrial fibrillation (AF), defined by disorganized atrial cardiac rhythm, is the most prevalent cardiac arrhythmia worldwide. Recent genetic studies have highlighted a major heritable component and identified numerous loci associated with AF risk, including the cardiogenic transcription factor genes TBX5, GATA4, and NKX2-5. We report that Tbx5 and Gata4 interact with opposite signs for atrial rhythm controls compared with cardiac development. Using mouse genetics, we found that AF pathophysiology caused by Tbx5 haploinsufficiency, including atrial arrhythmia susceptibility, prolonged action potential duration, and ectopic cardiomyocyte depolarizations, were all rescued by Gata4 haploinsufficiency. In contrast, Nkx2-5 haploinsufficiency showed no combinatorial effect. The molecular basis of the TBX5/GATA4 interaction included normalization of intra-cardiomyocyte calcium flux and expression of calcium channel genes Atp2a2 and Ryr2. Furthermore, GATA4 and TBX5 showed antagonistic interactions on an ...

Atrial Tissue Modeling<...
Atrial fibrillation is an abnormal heart rhythm characterized by rapid and irregular activation of the upper chambers of the heart. Atrial fibrillation often shows a natural progression towards longer and more frequently occurring episodes and often occurs in patients with existing heart disease(s). Because atrial fibrillation is highly complex and evolves over time, it is very difficult and expensive to study comprehensively in experiments or in the clinic.. Predictive multiscale computational modeling has the potential to fill this research void. We have incorporated many aspects of atrial fibrillation to model some of its various disease states. Our computational model consists of millions of virtual atrial cells coupled together to form a realistic three-dimensional atrial anatomy. Simulations of this model show that disease-like modifications to cellular processes, as well as to the coupling between cells, perpetuate simulated atrial fibrillation by accelerating the rhythm and/or increasing ...

Press Release issued Sep 10, 2013: Atrial fibrillation (AF) is characterized by irregular and often rapid heart rate responsible for poor blood flow to the body and is one of the most common types of arrhythmia. It occurs in cases where the -hearts electrical signals cause the atria to fibrillate, i.e. contract irregularly and very fast. The risk of developing atrial fibrillation usually occurs in the geriatric population and its risk is high in patients with mitral valve diseases, coronary heart disorder, congenital heart disease, cardiomyopathy, etc. Atrial fibrillation is also characterized by collection of blood in the atria and as a result there is absence of synchronization between the upper and lower chambers of the heart thereby increasing the risk of stroke.

Atrial fibrillation (commonly referred to as afib is a chaotic electrical circuit that occurs in the top two chambers of the heart called the atria. Healthy atria contracts 60-80 times per minute but atria in afib quiver at 300-400 times per minute. Essentially the heart of an afib patient works as if its enduring a marathon even if the patient is relaxing. As you can imagine, this can cause extreme fatigue as well as feelings such as flopping or pounding in the chest.. The most devastating result of afib is a stroke. The quivering atria can lead to slow blood flow and clot formation which can eventually go to the brain.. Risk factor modification, prevention of stroke, and treatment of symptoms are all addressed in our afib clinic.. Learn More About Atrial Fibrillation. ...

The function of the right side of the heart (see right heart) is to collect de-oxygenated blood, in the right atrium, from the body and pump it, via the right ventricle, into the lungs (pulmonary circulation) so that carbon dioxide can be dropped off and oxygen picked up (gas exchange). This happens through a passive process called diffusion. The left side (see left heart) collects oxygenated blood from the lungs into the left atrium. From the left atrium the blood moves to the left ventricle which pumps it out to the body. On both sides, the lower ventricles are thicker and stronger than the upper atria. The muscle wall surrounding the left ventricle is thicker than the wall surrounding the right ventricle due to the higher force needed to pump the blood through the systemic circulation.

  • Insurers will want to know what heart condition you have, when the pacemaker was implanted, what medications you take and any complications you may have experienced since having the device implanted. (termland.com)
Originates1
  • The heartbeat is created by an electrical signal that originates in an area of specialized cells in the heart's upper right chamber, the right atrium. (pvillage.org)
Electrical signals4
  • When a person has A-fib, these electrical signals become distorted, causing the atria to quiver, or twitch, erratically. (medicalnewstoday.com)
  • Changes in the electrical signals in the heart cause A-fib. (medicalnewstoday.com)
  • Ablating this tissue forms a scar (or lesion) that will stop or block these electrical signals, allowing the heart to beat properly. (medtronic.com)
  • By using a nitrous oxide refrigerant within a catheter frozen to minus 70 degrees Celsius, the team deduced, physicians could use cold energy to create the scar needed to address the uncontrolled electrical signals in the heart. (medtronic.com)
Rhythms2
  • For the study, the researchers tracked heart rhythms of 322 teens (average age 17) after they were exposed to pollution for 24 hours. (healthday.com)
  • Individuals with many heart conditions can lead normal lives and receive standard rates due to the success of pacemakers in restoring normal heart rhythms and effectively "curing" their condition. (termland.com)
