Among some of the symptoms consistent with pulmonary valve stenosis are the following:
- Heart murmur
- Cyanosis
- Dyspnea
- Dizziness
- Upper thorax pain
- Developmental disorders
In regards to the cause of pulmonary valve stenosis a very high percentage are congenital, the right ventricular flow is hindered (or obstructed by this). The cause in turn is divided into: valvular, external and intrinsic (when it is acquired).
Signs and symptoms of mitral stenosis include the following:
- Heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea (PND)
- Palpitations
- Chest pain
- Hemoptysis
- Thromboembolism in later stages when the left atrial volume is increased (i.e., dilation). The latter leads to increase risk of atrial fibrillation, which increases the risk of blood stasis (motionless). This increases the risk of coagulation.
- Ascites and edema and hepatomegaly (if right-side heart failure develops)
Fatigue and weakness increase with exercise and pregnancy.
A mild diastolic murmur can be heard during auscultation caused by the blood flow through the stenotic valve. It is best heard over the left sternal border with rumbling character and tricuspid opening snap with wide-splitting S1. It may increase in intensity with inspiration (Carvallo's sign). The diagnosis will typically be confirmed by an echocardiograph, which will also allow the physician to assess its severity.
In many cases, a bicuspid aortic valve will cause no problems. People with BAV may become tired more easily than those with normal valvular function and have difficulty maintaining stamina for cardio-intensive activities due to poor heart performance.
Signs/symptoms of tricuspid insufficiency are generally those of right-sided heart failure, such as ascites and peripheral edema.
Tricuspid insufficiency may lead to the presence of a pansystolic heart murmur. Such a murmur is usually of low frequency and best heard low on the lower left sternal border. As with most right-sided phenomena, it tends to increase with inspiration, and decrease with expiration. This is known as Carvallo's sign. However, the murmur may be inaudible indicating the relatively low pressures in the right side of the heart. A third heart sound may also be present, also heard with inspiration at the lower sternal border.
In addition to the possible ausculatory findings above, there are other signs indicating the presence of tricuspid regurgitation. There may be giant C-V waves in the jugular pulse and a palpably (and sometimes visibly) pulsatile liver on abdominal exam. Since the murmur of tricupsid regurgitation may be faint or inaudible, these signs can be helpful in establishing the diagnosis.
Pulmonary and tricuspid valve diseases are right heart diseases. Pulmonary valve diseases are the least common heart valve disease in adults.
Pulmonary valve stenosis is often the result of congenital malformations and is observed in isolation or as part of a larger pathologic process, as in Tetralogy of Fallot, Noonan syndrome, and congenital rubella syndrome . Unless the degree of stenosis is severe individuals with pulmonary stenosis usually have excellent outcomes and treatment options. Often patients do not require intervention until later in adulthood as a consequence of calcification that occurs with aging.
Pulmonary valve insufficiency occurs commonly in healthy individuals to a very mild extent and does not require intervention. More appreciable insufficiency it is typically the result of damage to the valve due to cardiac catheterization, aortic balloon pump insertion, or other surgical manipulations. Additionally, insufficiency may be the result of carcinoid syndrome, inflammatory processes such a rheumatoid disease or endocarditis, or congenital malformations. It may also be secondary to severe pulmonary hypertension.
Tricuspid valve stenosis without co-occurrent regurgitation is highly uncommon and typically the result of rheumatic disease. It may also be the result of congenital abnormalities, carcinoid syndrome, obstructive right atrial tumors (typically lipomas or myxomas), or hypereosinophilic syndromes.
Minor tricuspid insufficiency is common in healthy individuals. In more severe cases it is a consequence of dilation of the right ventricle, leading to displacement of the papillary muscles which control the valve's ability to close. Dilation of the right ventricle occurs secondary to ventricular septal defects, right to left shunting of blood, eisenmenger syndrome, hyperthyroidism, and pulmonary stenosis. Tricuspid insufficiency may also be the result of congenital defects of the tricuspid valve, such as Ebstein's anomaly.
Symptoms related to aortic stenosis depend on the degree of stenosis. Most people with mild to moderate aortic stenosis do not have symptoms. Symptoms usually present in individuals with severe aortic stenosis, though they may occur in those with mild to moderate aortic stenosis as well. The three main symptoms of aortic stenosis are loss of consciousness, anginal chest pain and shortness of breath with activity or other symptoms of heart failure such as shortness of breath while lying flat, episodes of shortness of breath at night, or swollen legs and feet. It may also be accompanied by the characteristic "Dresden china" appearance of pallor with a light flush.
Bicuspid aortic valves may assume three different types of configuration:
1. "Real" bicuspid valves with two symmetric leaflets
2. A tricuspid architecture with a fusion of two leaflets
3. A tricuspid architecture with a fusion of three leaflets
A right ventricular outflow tract obstruction (RVOTO) may be due to a defect in the pulmonic valve, the supravalvar region, the infundibulum, or the pulmonary artery.
- Pulmonary atresia
- Pulmonary valve stenosis
- Hypoplastic right heart syndrome
- Tetralogy of Fallot
Mitral stenosis is a valvular heart disease characterized by the narrowing of the orifice of the mitral valve of the heart.
The annulus of the valve is still in the normal position. The valve leaflets, however, are to a varying degree, attached to the walls and septum of the right ventricle. A subsequent 'atrialization' of a portion of the morphologic right ventricle (which is then contiguous with the right atrium) is seen. This causes the right atrium to be large and the anatomic right ventricle to be small in size.
- S3 heart sound
- S4 heart sound
- Triple or quadruple gallop due to widely split S1 and S2 sounds plus a loud S3 and/or S4
- Systolic murmur of tricuspid regurgitation = Holosystolic or early systolic murmur along the lower left sternal border depending on the severity of the regurgitation
- Right atrial hypertrophy
- Right ventricular conduction defects
- Wolff-Parkinson-White syndrome often accompanies
Ventricular septal defect is usually symptomless at birth. It usually manifests a few weeks after birth.
VSD is an acyanotic congenital heart defect, aka a left-to-right shunt, so there are no signs of cyanosis in the early stage. However, uncorrected VSD can increase pulmonary resistance leading to the reversal of the shunt and corresponding cyanosis.
- Pansystolic (Holosystolic) murmur along lower left sternal border (depending upon the size of the defect) +/- palpable thrill (palpable turbulence of blood flow). Heart sounds are normal. Larger VSDs may cause a parasternal heave, a displaced apex beat (the palpable heartbeat moves laterally over time, as the heart enlarges). An infant with a large VSD will fail to thrive and become sweaty and tachypnoeic (breathe faster) with feeds.
The restrictive VSDs (smaller defects) are associated with a louder murmur and more palpable thrill (grade IV murmur). Larger defects may eventually be associated with pulmonary hypertension due to the increased blood flow. Over time this may lead to an Eisenmenger's syndrome the original VSD operating with a left-to-right shunt, now becomes a right-to-left shunt because of the increased pressures in the pulmonary vascular bed.
Angina in setting of heart failure also increases the risk of death. In people with angina, the 5-year mortality rate is 50% if the aortic valve is not replaced.
Angina in the setting of AS occurs due to left ventricular hypertrophy (LVH) that is caused by the constant production of increased pressure required to overcome the pressure gradient caused by the AS. While the muscular layer of the left ventricle thickens, the arteries that supply the muscle do not get significantly longer or bigger, so the muscle may not receive enough blood supply to meet its oxygen requirement. This ischemia may first be evident during exercise when the heart muscle requires increased blood supply to compensate for the increased workload. The individual may complain of anginal chest pain with exertion. At this stage, a cardiac stress test with imaging may be suggestive of ischemia.
Eventually, however, the heart muscle will require more blood supply at rest than can be supplied by the coronary artery branches. At this point there may be signs of "ventricular strain pattern" (ST segment depression and T wave inversion) on the EKG, suggesting subendocardial ischemia. The subendocardium is the region that is most susceptible to ischemia because it is the most distant from the epicardial coronary arteries.
A left ventricular outflow tract obstruction (LVOTO) may be due to a defect in the aortic valve, or a defect located at the subvalvar or supravalvar level.
- Aortic valve stenosis
- Supravalvar aortic stenosis
- Coarctation of the aorta
- Hypoplastic left heart syndrome
Major symptoms of Lutembacher's syndrome as a result of ASD and MS can range from heart failure to pulmonary congestion.
- Right ventricular overload and Right-sided heart failure: Both are caused by a large ASD and MS (moderate to severe).
- Palpitations: This is caused by blood flowing from left atrium to the right atrium causing a higher left atrial pressure and leading to mitral stenosis. Both atria will be dilated (stretched or open)leading to future atrial arrhythmias or atrial fibrillation (Riaz).
- Pulmonary congestion: When blood or fluid pools within the lungs; this is usually a symptom of mitral stenosis and a small ASD.
- Loud mitral S1 and wide fixed split of pulmonary S2: The loud sound of the mitral S1 and the wide fixed split of pulmonary S2 is a symptoms of mitral stenosis. The sounds often are caused by a reduced pressure gradient in the mitral area that was caused from decompression of the left atrium from the ASD and a displacement (moving from normal position) of the left ventricular lower portion of the heart to the a large right ventricle. The second heart sound (S2) split is caused by the increase right heart blood flow through the ASD causing a late closing of the pulmonary component of the S2 as well as decreased left ventricular and aortic blood flow.
- III/IV mid diastolic murmur, early systolic murmur: This heart murmur is caused by an increase blood flow through the tricuspid valve due to ASD; it is heard best in the left lower sternal area or the bottom of the heart (apex).
An enlargement of the aorta may occur; an increased risk of abnormality is seen in babies of women taking lithium during the first trimester of pregnancy (though some have questioned this) and in those with Wolff-Parkinson-White syndrome.
Fetal aortic stenosis is a disorder that occurs when the fetus’ aortic valve does not fully open during development. The aortic valve is a one way valve that is located between the left ventricle and the aorta, keeping blood from leaking back into the ventricle. It has three leaflets that separate when the ventricle contracts to allow blood to move from the ventricle to the aorta. These leaflets come together when the ventricle relaxes.
A defect in the ostium primum is occasionally classified as an atrial septal defect, but it is more commonly classified as an atrioventricular septal defect
A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle. The ventricular septum consists of an inferior muscular and superior membranous portion and is extensively innervated with conducting cardiomyocytes.
The membranous portion, which is close to the atrioventricular node, is most commonly affected in adults and older children in the United States. It is also the type that will most commonly require surgical intervention, comprising over 80% of cases.
Membranous ventricular septal defects are more common than muscular ventricular septal defects, and are the most common congenital cardiac anomaly.
Heart valve dysplasia is an error in the development of any of the heart valves, and a common cause of congenital heart defects in humans as well as animals; tetralogy of Fallot is a congenital heart defect with four abnormalities, one of which is stenosis of the pulmonary valve. Ebstein's anomaly is an abnormality of the tricuspid valve.
Tricuspid Valve Stenosis is a valvular heart disease that narrows the opening of the heart's tricuspid valve. It is a relatively rare condition that causes stenosis-increased restriction of blood flow through the valve.
As Lutembacher's syndrome is known for ASD and MS, most of the symptoms experienced will be associated with ASD and MS. For most people, they will remain asymptomatic (experience no symptoms) but when symptoms are shown, they are due mainly to ASD and will vary depending on the size of the hole in the atria. If the patient has a large ASD, pulmonary congestion (blood or fluid buildup in the lungs) will happen later but if the patient has a small ASD, symptoms will appear early in the disorder. In general, unless the ASD and mitral stenosis causing Lutembacher's syndrome is severe, symptoms may not appear until the second and third decade of the patient's life. As many of the symptoms are asymptomic and may not appear until later in life, the duration or frequency of the symptoms varies. For symptoms such as palipitations, ventricular overload, heart failure, and pulmonary congenstion, these symptoms may be sudden and not that frequent as they are very severe symptoms. For symptoms such as loud mitral S1, pulmonary S2, mid-diastolic murmur, fatigue, reduced exercise tolerance, weight gain, ankle edema, and right upper quadrant pain, and ascities, these symptoms may be less frequent and severe; their duration may be only a few seconds, minutes, or even months.
Fetal aortic valve stenosis can be diagnosed by echocardiography before birth. The diagnostic features include a poorly contracting left ventricle, aortic valve thickening/restriction, a varying degree of left ventricular hypertrophy and abnormal Doppler flow characteristics in the left heart. There may be little or no detectable flow into or out of the left side of the heart.
There are two screening periods, one during the first trimester and the other during the second trimester. Fetal aortic stenosis is typically detected between 18 and 24 weeks gestation. This early detection is important because it allows for parents to be counseled in a timely and rational manner, allowing for discussion of prognosis and possible outcomes. Another reason for this crucial early detection is because it allows for postnatal management planning.
Tricuspid insufficiency (TI), a valvular heart disease also called tricuspid regurgitation (TR), refers to the failure of the heart's tricuspid valve to close properly during systole. This defect allows the blood to flow backwards, reducing its efficiency.
Regurgitation may be due to a structural change of components of the tricuspid valve apparatus, a lesion can be primary (intrinsic abnormality) or secondary (right ventricular dilatation).
