What does enlargement of the ventricles mean?

Left ventricular hypertrophy is a thickening of the wall of the heart’s main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure.

Can enlarged brain ventricles be normal?

The brain may shrink in older patients or those with Alzheimer’s disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.

What are the symptoms of enlarged ventricles?

Physical signs and symptoms

  • Nausea and vomiting.
  • Sleepiness or sluggishness (lethargy)
  • Irritability.
  • Poor eating.
  • Seizures.
  • Eyes fixed downward (sunsetting of the eyes)
  • Problems with muscle tone and strength.

What disorder is associated with enlarged ventricles?

Hydrocephalus is an abnormal buildup of fluid in the ventricles (cavities) deep within the brain. This excess fluid causes the ventricles to widen, putting pressure on the brain’s tissues. Cerebrospinal fluid (CSF) is the clear, colorless fluid that protects and cushions the brain and spine.

How are enlarged ventricles treated?

Treatment is usually only required if a baby shows signs of developing hydrocephalus. The aim of treatment is to reduce the pressure on the brain by draining away the CSF. In most cases, the fluid is drained away using a ‘shunt’, which is a long tube made of silicone.

What causes an enlarged left ventricle?

The most common cause of left ventricular hypertrophy is high blood pressure (hypertension). High blood pressure makes your heart work harder than normal. The extra work it takes to pump blood can cause the muscle in the left ventricle walls to get larger and thicker.

Is the left ventricle bigger than the right?

Although the right and left ventricles contain equal amounts of blood, the left ventricle is larger because it has thicker walls. These thicker walls enable pressure to develop enough to push blood throughout the body.

Can mild ventriculomegaly get worse?

Ventriculomegaly will significantly worsen in approximately 2-5% of cases. In many fetuses, particularly those with borderline ventriculomegaly, the condition will resolve spontaneously resulting in a normal outcome. The major factor that influences prognosis is the presence of associated abnormalities.

What is the life expectancy of someone with left ventricular hypertrophy?

What Is the Life Expectancy for Hypertrophic Cardiomyopathy? The majority of patients with hypertrophic cardiomyopathy have no symptoms and most have a near-normal life expectancy. In some cases, sudden cardiac death is the first symptom of the illness.

How do you reverse an enlarged left ventricle?

Treatment for left ventricular hypertrophy depends on the underlying cause. It may include medications, catheter procedures or surgery.


  1. Angiotensin-converting enzyme inhibitors.
  2. Angiotensin II receptor blockers.
  3. Beta blockers.
  4. Calcium channel blockers.
  5. Water pills, also called diuretics.

What does it mean when one side of the heart is larger?

High blood pressure in the arteries in the lungs (pulmonary hypertension). The heart has to work harder to move blood between the lungs and the heart. The strain may lead to thickening or enlargement of the right side of the heart.

Which side of the heart is stronger?

The left ventricle is the strongest because it has to pump blood out to the entire body. When your heart functions normally, all four chambers work together in a continuous and coordinated effort to keep oxygen-rich blood circulating throughout your body.

Should I worry about mild ventriculomegaly?

Outcomes for babies with ventriculomegaly depend on both the cause of the ventriculomegaly and whether it is progressive or not. Most children with mild, nonprogressive cases that do not involve brain damage or developmental anomalies will not have any long-term health effects. More severe cases may need surgery.

How fast does ventriculomegaly progress?

The mean rate of progression in the mild group was 1.07 (SD 1.03) mm/week, whereas in the moderate group progression was at a mean rate of 1.41 (SD 0.77) mm/week. Progression of severe ventriculomegaly was significantly higher at a mean rate of 3.26 (SD 2.92) mm/week (p = 0.007).

What does an enlarged left ventricle mean?

What is Left Ventricular Hypertrophy (LVH)? Left ventricular hypertrophy, or LVH, is a term for a heart’s left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle.

What causes left ventricle enlargement?

What is worse right or left heart failure?

The left ventricle is larger and stronger than the right because it has to pump blood through your whole body. When people have left-sided heart failure, their heart’s left side has to work harder to pump the same amount of blood.

What happens when one side of your heart is bigger than the other?

This larger size can increase blood pressure in your heart, which increases the force placed on arteries and blood vessels throughout the rest of your body. It’s also harder for a larger heart to conduct the electrical impulses that keep it beating, leading to serious health problems.

Can mild ventriculomegaly go away?

It is benign in up to 90% of cases, although it can be associated with genetic, structural, and neurocognitive disorders. The literature suggests that over 40% of isolated mild ventriculomegaly will resolve in utero, but it is unclear if resolution decreases the associated risks.

Does ventriculomegaly mean Down syndrome?

Ventriculomegaly is defined as a width of 10 mm or greater of the lateral ventricles at the level of the atria (Fig. 151.4). It is associated with an increased risk of aneuploidy, including Down syndrome. In a large series of 2743 cases, 3.8% of fetuses had aneuploidy, and 2% of all cases had Down syndrome.

Can the left ventricle repair itself?

Until recently, it was believed that the human heart didn’t have this capacity. But the heart does have some ability to make new muscle and possibly repair itself. The rate of regeneration is so slow, though, that it can’t fix the kind of damage caused by a heart attack.

What does a heart failure cough sound like?

You may experience a persistent cough or wheezing (a whistling sound in the lungs or laboured breathing) due to your heart failure.

What happens if left ventricle is enlarged?

In response to this pressure overload, the inner walls of the heart may respond by getting thicker. These thickened walls can cause the left ventricle to weaken, stiffen and lose elasticity, which may prevent healthy blood flow.

How quickly does ventriculomegaly progress?

Progression of severe ventriculomegaly was significantly higher at a mean rate of 3.26 (SD 2.92) mm/week (p = 0.007). Conclusions: The majority of fetuses with mild ventriculomegaly normalized, whereas the majority of moderate cases remained stable. The rate of progression of ventriculomegaly increased with severity.

Is ventriculomegaly a birth defect?

The severity of ventriculomegaly depends on how enlarged the brain is. In some cases, fluid keeps building up, and the ventricles grow larger over time. This condition is known as hydrocephalus. Ventriculomegaly is the most common fetal brain abnormality, occurring in up to 1.5 per 1,000 pregnancies.
