The atria become severely enlarged and because the ventricles are stiff, blood backs up into the atria. As a result, not enough blood is pumped to meet the body's needs. </figcaption> </figure> <p>In restrictive cardiomyopathy (RCM), the <a href="/Article?contentid=1577&language=English">heart muscle</a> becomes very stiff, so it does not stretch in the relaxation phase when it needs to fill with blood.

However, it is also the most serious type of cardiomyopathy and has the fewest treatment options.</p><p>It is difficult to treat this condition with medications. A heart transplant may be required.</p><h2>Complications of RCM</h2><p>RCM can result in “back pressure” into the lungs and right side of the heart which can cause shortness of breath or fluid in your child’s lungs and/or belly. There is also a higher risk of <a href="/Article?contentid=890&language=English">abnormal heart rhythms</a> with this condition and many children will require blood thinners (anti-coagulation) to reduce the risk of blood clot formation.</p>
