As an actively practicing clinical cardiologist for many years in three different communities, I knew about myocarditis. I just never saw it. Quite literally, I recall seeing ONE young woman who presented with a picture of acute congestive heart failure, and her echocardiogram study revealed a big and poorly contracting heart. Such a condition is diagnosed as an idiopathic congestive cardiomyopathy, which basically means the heart is enlarged and functioning very poorly, and you have no idea why. After treating her with traditional measures for congestive heart failure, she started getting better. To my great surprise, after six to nine months of follow-up, her echocardiogram had returned to normal.
