The most common cause of reoperation is a leaky pulmonary valve (pulmonary valve insufficiency). [61] This is usually corrected with a procedure called pulmonary valve replacement. [24]: 136 One common prognostic factor with TOF is the development of ischemia reperfusion injury. Insufficient myocardial protection is considered one of the main ...
Single PVCs are common in healthy persons. When 24-hour ambulatory monitoring is used, up to 80 percent of apparently healthy people have occasional PVCs. [27] Rates vary by age with extremely rare for those under the age of 11 and extremely common in those older than 75 years. [28]
Benign paroxysmal positional vertigo (BPPV) - This is the most common cause of vertigo in adults, but it is rarer in children. Unlike BPVC, BPPV is provoked by changes in the head position.

The term childhood disease refers to disease that is contracted or becomes symptomatic before the age of 18 or 21 years old. Many of these diseases can also be contracted by adults. Some childhood diseases include:
The most common underlying anatomical cause of PSVT is atrioventricular nodal reentry, which accounts for more than half of the cases. [ 9 ] The underlying anatomical causes of PSVT, specifically atrioventricular nodal reentry, involve the presence of two functionally distinct conduction pathways within the AV node and the formation of a ...
Over time, affected children experience mental impairment, worsening seizures and progressive loss of sight, speech and motor skills. Batten disease is a terminal disease; life expectancy varies depending on the type or variation. [7] [8] Females with juvenile Batten disease show first symptoms a year later than males, but on average die a year ...
Between 1990 and 2010 prematurity was the second leading cause of worldwide mortality for neonates and children under the age of five. [27] The overall PTB mortality rate in 2010 was 11.1% (15 million deaths) worldwide and was highest in low to middle-income countries in sub-Saharan Africa and south Asia (60% of all PTBs), compared with high ...
[3] [12] In about 6 to 19 per 1,000 they cause a moderate to severe degree of problems. [12] Congenital heart defects are the leading cause of birth defect-related deaths: [3] in 2015, they resulted in 303,300 deaths, down from 366,000 deaths in 1990. [13] [14] The cause of a congenital heart defect is often unknown. [4]
