Cardiomediastinal enlargement-Enlarged heart - Symptoms and causes - Mayo Clinic

The term "cardiomegaly" refers to an enlarged heart seen on any imaging test, including a chest X-ray. Other tests are then needed to diagnose the condition causing your enlarged heart. You may develop an enlarged heart temporarily because of a stress on your body, such as pregnancy, or because of a medical condition, such as the weakening of the heart muscle, coronary artery disease, heart valve problems or abnormal heart rhythms. Certain conditions may cause the heart muscle to thicken or one of the chambers of the heart to dilate, making the heart larger. Depending on the condition, an enlarged heart may be temporary or permanent.

Chest radiography Figure 1 revealed enlargement of the cardiac silhouette, with a disproportionately increased transverse diameter, and an obscured left costophrenic angle. In some people, an enlarged heart causes no signs or symptoms.

It is defined as follows:.

  • It is defined as follows:.
  • Cardiomediastinal refers to the mediastinum, which is the area between the lungs that contains the heart, esophagus and thymus.

A year-old woman with a history of hypertension and left-lung lobectomy for a carcinoid tumor 10 years ago presented with a 2-week history of progressive cough, dyspnea, and fatigue. Her heart rate was beats per minute with an irregularly irregular rhythm, and her respiratory rate was 36 breaths per minute.

Examination revealed decreased breath sounds and dullness on percussion at the left lung base, jugular venous distention with a positive hepatojugular reflux sign, and an enlarged liver. Electrocardiography showed atrial fibrillation. Chest radiography Figure 1 revealed enlargement of the cardiac silhouette, with a disproportionately increased transverse diameter, and an obscured left costophrenic angle.

A radiograph taken 13 months earlier Figure 1 had shown a normal cardiothoracic ratio. Figure 1. Posteroanterior chest radiograph at the time of presentation A showed enlargement of the cardiac silhouette, with a disproportionately increased transverse diameter, a relatively normal lung vascular marking, and an obscured left costophrenic angle. A radiograph obtained 13 months earlier B had shown a normal cardiothoracic ratio and visible costophrenic angles. Pericardial effusion should be suspected in patients presenting with symptoms of impaired cardiac function such as fatigue, dyspnea, nausea, palpitations, lightheadedness, cough, and hoarseness.

Patients may also present with chest pain, often decreased by sitting up and leaning forward and exacerbated by lying supine. Physical examination may reveal distant heart sounds, an absent or displaced apical impulse, dullness and increased fremitus beneath the angle of the left scapula the Ewart sign , pulsus paradoxus, and nonspecific findings such as tachycardia and hypotension. Jugular venous distention, hepatojugular reflux, and peripheral edema suggest impaired cardiac function.

A chest radiograph showing unexplained new symmetric cardiomegaly which is often globe-shaped without signs of pulmonary congestion 1 or with a left dominant pleural effusion is an indicator of pericardial effusion, as in our patient. Pericardial fluid may be seen outlining the heart between the epicardial and mediastinal fat, posterior to the sternum in a lateral view. Other common causes of cardiomegaly include hypertension, congestive heart failure, valvular disease, cardiomyopathy, ischemic heart disease, and pulmonary disease.

Once pericardial effusion is suspected, the next step is to confirm its presence and determine its hemodynamic significance. Transthoracic echocardiography is the imaging test of choice to confirm effusion, as it can be done rapidly and in unstable patients. Pericardial effusion can occur as part of various diseases involving the pericardium, eg, acute pericarditis, myocarditis, autoimmune disease, postmyocardial infarction, malignancy, aortic dissection, and chest trauma.

It can also be associated with certain drugs. Figure 2. Transthoracic echocardiography demonstrated pericardial effusion PE surrounding the heart. In our patient, echocardiography Figure 2, Figure 3 demonstrated a large amount of pericardial fluid, and mL of red fluid was aspirated by pericardiocentesis, resulting in relief of her respiratory symptoms.

Subcostal two-dimensional echocardiography demonstrated rocking of the heart and intermittent right-ventricular collapse watch video at www. Figure 3. M-mode echocardiography upper panel through the right ventricle RV and left ventricle LV showed ventricular respiratory interdependence increased RV volume causing decreased LV volume and vice versa and transient inspiratory RV collapse.

Echocardiographic pulse-wave Doppler ultrasonography of the mitral inflow lower panel showed increased E-wave velocity respiratory variability passive LV filling , suggesting ventricular interdependence. Malignant tumors of the lung, breast, and esophagus—as well as lymphoma, leukemia, and melanoma—often spread to the pericardium directly or through the lymphatic vessels or bloodstream.

Consider it when the patient has chest trauma or a chronic medical illness Acute pericarditis has a unique clinical presentation, physical findings, and electrocardiographic changes.

The term "cardiomegaly" refers to an enlarged heart seen on any imaging test, including a chest X-ray. Other tests are then needed to diagnose the condition causing your enlarged heart. You may develop an enlarged heart temporarily because of a stress on your body, such as pregnancy, or because of a medical condition, such as the weakening of the heart muscle, coronary artery disease, heart valve problems or abnormal heart rhythms.

Certain conditions may cause the heart muscle to thicken or one of the chambers of the heart to dilate, making the heart larger. Depending on the condition, an enlarged heart may be temporary or permanent.

An enlarged heart may be treatable by correcting the cause. Treatment for an enlarged heart can include medications, medical procedures or surgery. In some people, an enlarged heart causes no signs or symptoms. Others may have these signs and symptoms:. An enlarged heart is easier to treat when it's detected early, so talk to your doctor if you have concerns about your heart. If you have new signs or symptoms that might be related to your heart, make an appointment to see your doctor.

Seek emergency medical care if you have any of these signs and symptoms, which may mean you're having a heart attack:.

An enlarged heart can be caused by conditions that cause your heart to pump harder than usual or that damage your heart muscle. Sometimes the heart enlarges and becomes weak for unknown reasons idiopathic.

A heart condition you're born with congenital , damage from a heart attack or an abnormal heartbeat arrhythmia can cause your heart to enlarge. Other conditions associated with an enlarged heart include:. High blood pressure.

Your heart may have to pump harder to deliver blood to the rest of your body, enlarging and thickening the muscle. High blood pressure can cause the left ventricle to enlarge, causing the heart muscle eventually to weaken. High blood pressure may also enlarge the upper chambers of your heart atria.

You may have a greater risk of developing an enlarged heart if you have any of the following risk factors:. The risk of complications from an enlarged heart depends on the part of the heart that is enlarged and the cause. Tell your doctor if you have a family history of conditions that can cause an enlarged heart, such as cardiomyopathy.

If cardiomyopathy or other heart conditions are diagnosed early, treatments may prevent the disease from worsening. Controlling risk factors for coronary artery disease — tobacco use, high blood pressure, high cholesterol and diabetes — helps to reduce your risk of an enlarged heart and heart failure by reducing your risk of a heart attack. You can help reduce your chance of developing heart failure by eating a healthy diet and not abusing alcohol or using illicit drugs.

Controlling high blood pressure with diet, exercise and possibly medications also prevents many people who have an enlarged heart from developing heart failure.
