When congenital heart disease shows up in the form of a malformed heart at birth, surgical repair is often possible to correct immediate problems.

Other more serious congenital heart diseases include various conditions that lead to cyanosis, in which a substantial mixing of oxygenated and deoxygenated blood occurs.

 FuturePundit: Some Day You May Take An Aphrodisiac For Your Heart
In a surprising result, the researchers found that heart function, as measured by pressure-volume analysis of the muscle's ability to contract and pump blood, actually improved after hypertrophy had been stopped and treated.
Improvements were seen in more than 10 measures of heart function, including heart relaxation, cardiac output and heart contractility, which increased by nearly 40 percent.
While researchers previously thought that hypertrophy was an adaptive response to pressure stress, the functional gains lasted despite the heart's continued exposure to high blood pressure.
