Instead of the muscle being smooth and firm, the cardiac muscle in the left ventricle is thick and appears spongy. The abnormal cardiac muscle is weak and has an impaired ability to pump blood because it either cannot completely contract or it cannot completely relax. For the heart to pump blood normally, cardiac muscle must contract and relax fully.\n\nSome individuals with left ventricular noncompaction experience no symptoms at all; others have heart problems that can include sudden cardiac death. Additional signs and symptoms include abnormal blood clots, irregular heart rhythm (arrhythmia), a sensation of fluttering or pounding in the chest (palpitations), extreme fatigue during exercise (exercise intolerance), shortness of breath (dyspnea), fainting (syncope), swelling of the legs (lymphedema), and trouble laying down flat. Some affected individuals have features of other heart defects. Left ventricular noncompaction can be diagnosed at any age, from birth to late adulthood. Approximately two-thirds of individuals with left ventricular noncompaction develop heart failure." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln">Left ventricular noncompaction is a heart (cardiac) muscle disorder that occurs when the lower left chamber of the heart (left ventricle), which helps the heart pump blood, does not develop correctly. Instead of the muscle being smooth and firm, the cardiac muscle in the left ventricle is thick and appears spongy. The abnormal cardiac muscle is weak and has an impaired ability to pump blood because it either cannot completely contract or it cannot completely relax. For the heart to pump blood normally, cardiac muscle must contract and relax fully.<br /><br />Some individuals with left ventricular noncompaction experience no symptoms at all; others have heart problems that can include sudden cardiac death. Additional signs and symptoms include abnormal blood clots, irregular heart rhythm (arrhythmia), a sensation of fluttering or pounding in the chest (palpitations), extreme fatigue during exercise (exercise intolerance), shortness of breath (dyspnea), fainting (syncope), swelling of the legs (lymphedema), and trouble laying down flat. Some affected individuals have features of other heart defects. Left ventricular noncompaction can be diagnosed at any age, from birth to late adulthood. Approximately two-thirds of individuals with left ventricular noncompaction develop heart failure. [from <a title="MedlinePlus Genetics" href="https://medlineplus.gov/genetics/" class="defSource" target="_blank">MedlinePlus Genetics</a>]</div>

<div class="spaceAbove">Sick sinus syndrome (also known as sinus node dysfunction) is a group of related heart conditions that can affect how the heart beats. "Sick sinus" refers to the sino-atrial (SA) node, which is an area of specialized cells in the heart that functions as a natural pacemaker. The SA node generates electrical impulses that start each heartbeat. These signals travel from the SA node to the rest of the heart, signaling the heart (cardiac) muscle to contract and pump blood. In people with sick sinus syndrome, the SA node does not function normally. In some cases, it does not produce the right signals to trigger a regular heartbeat. In others, abnormalities disrupt the electrical impulses and prevent them from reaching the rest of the heart.\n\nSick sinus syndrome tends to cause the heartbeat to be too slow (bradycardia), although occasionally the heartbeat is too fast (tachycardia). In some cases, the heartbeat rapidly switches from being too fast to being too slow, a condition known as tachycardia-bradycardia syndrome. Symptoms related to abnormal heartbeats can include dizziness, light-headedness, fainting (syncope), a sensation of fluttering or pounding in the chest (palpitations), and confusion or memory problems. During exercise, many affected individuals experience chest pain, difficulty breathing, or excessive tiredness (fatigue). Once symptoms of sick sinus syndrome appear, they usually worsen with time. However, some people with the condition never experience any related health problems.\n\nSick sinus syndrome occurs most commonly in older adults, although it can be diagnosed in people of any age. The condition increases the risk of several life-threatening problems involving the heart and blood vessels. These include a heart rhythm abnormality called atrial fibrillation, heart failure, cardiac arrest, and stroke.</div>

<div class="spaceAbove">Left ventricular noncompaction (LVNC) is characterized by numerous prominent trabeculations and deep intertrabecular recesses in hypertrophied and hypokinetic segments of the left ventricle (Sasse-Klaassen et al., 2004). The mechanistic basis is thought to be an intrauterine arrest of myocardial development with lack of compaction of the loose myocardial meshwork. LVNC may occur in isolation or in association with congenital heart disease. Distinctive morphologic features can be recognized on 2-dimensional echocardiography (Kurosaki et al., 1999). Noncompaction of the ventricular myocardium is sometimes referred to as spongy myocardium. Stollberger et al. (2002) commented that the term 'isolated LVNC,' meaning LVNC without coexisting cardiac abnormalities, is misleading, because additional cardiac abnormalities are found in nearly all patients with LVNC.&#13; Genetic Heterogeneity of Left Ventricular Noncompaction&#13; A locus for autosomal dominant left ventricular noncompaction has been identified on chromosome 11p15 (LVNC2; 609470).&#13; LVNC3 (see 605906) is caused by mutation in the LDB3 gene (605906) on chromosome 10q23. LVNC4 (see 613424) is caused by mutation in the ACTC1 gene (102540) on chromosome 15q14. LVNC5 (see 613426) is caused by mutation in the MYH7 gene (160760) on chromosome 14q12. LVNC6 (see 601494) is caused by mutation in the TNNT2 gene (191045) on chromosome 1q32. LVNC7 (615092) is caused by mutation in the MIB1 gene (608677) on chromosome 18q11. LVNC8 (615373) is caused by mutation in the PRDM16 gene (605557) on chromosome 1p36. LVNC9 (see 611878) is caused by mutation in the TPM1 gene (191010) on chromosome 15q22. LVNC10 (615396) is caused by mutation in the MYBPC3 gene (600958) on chromosome 11p11.&#13; LVNC can also occur as part of an X-linked disorder, Barth syndrome (302060), caused by mutation in the TAZ gene (300394) on chromosome Xq28.</div>

Instead of the muscle being smooth and firm, the cardiac muscle in the left ventricle is thick and appears spongy. The abnormal cardiac muscle is weak and has an impaired ability to pump blood because it either cannot completely contract or it cannot completely relax.
