Advances in genetic testing have changed the approach to genetic diagnoses of the cardiomyopathies
. Familial DCM is the most genetically heterogeneous of the cardiomyopathies
'We are optimistic that the scientific insights that emerge from the work of MyoSeeds awardees will be useful in gaining a better understanding of the biology of cardiomyopathies
, and ultimately advancing patient care.'
LVNC is a rare, yet recognized cause of cardiomyopathy, with a prevalence of 0.014% in adult population.3 Our patient was a male and it is recognized that LVNC occurs more often in men than in women.2,4 LVNC has been described occurring alone and as a part of complex congenital heart diseases and other forms of cardiomyopathies
. In our case, LVNC was an isolated finding without other congenital cardiac malformations.The presentation of patients with LVNC depends on the stage of disease.
The results of our study helped in identification of patients with cardiomyopathies
that are at risk of fatal arrhythmias.
The mouse models were either normal (wild type) mice or those expressing different gene mutations for various cardiomyopathies
(1-8) Arrhythmogenic cardiomyopathy is the only primary cardiomyopathy with a concealed phase, which is reminiscent of the ion channelopathies and means that AC shares features of both conventional cardiomyopathies
and inherited arrhythmias.

SAN FRANCISCO -- Genetic testing for the cardiomyopathies
and channelopathies has entered the realm of daily clinical practice with the release of comprehensive joint guidelines by the Heart Rhythm Society and the European Heart Rhythm Association.
