The aetiology for tympanosclerosis is not extensively understood. There are several probable factors which could result in the condition appearing, including: Long term otitis media (or 'glue ear') [2] Insertion of a tympanostomy tube. [4] [5] [6] If aspiration is performed as part of the insertion, the risk of tympanosclerosis occurring ...
Stenosis causes your heart valves to narrow or harden, limiting blood flow and putting extra stress on the heart muscle because it needs to squeeze harder to move blood forward. Regurgitation or ...
Dr. Davis emphasizes that valve damage is not only caused by poor dietary habits, explaining, “Diet is often talked about in connection to heart disease, but valve damage has different causes. A ...
When over-activated this process causes thickening and fibrosis of the valve, with white tissue building up primarily on the tricuspid valve, but also occurring on the pulmonary valve. The thickening and loss of flexibility eventually may lead to valvular dysfunction and right-sided heart failure.
A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart. Heart valves are opened or closed by a difference in blood pressure on each side. [1] [2] [3]
Other diseases that cause heart muscle dysfunction are excluded, such as coronary artery disease, hypertension, or abnormalities of the heart valves. [17] Often, the underlying cause remains unknown, but in many cases the cause may be identifiable. [18] Alcoholism, for example, has been identified as a cause of dilated cardiomyopathy, as has ...
Pulmonary valve diseases are the least common heart valve disease in adults. [1] [4] 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 ...
Due to its low frequency of occurrence, more common causes of hoarseness should be considered when suspecting left recurrent laryngeal nerve palsy (LRLN).. When considering cardiovocal syndrome, the most common historical cause is a dilated left atrium due to mitral stenosis, but other causes, including pulmonary hypertension, [2] thoracic aortic aneurysms, an enlarged pulmonary artery [3] and ...
