I am an experienced cardiac sonographer with an abiding interest in
imaging all forms of congenital heart disease, from discovery through palliation/repair.
I have a somewhat fanatical obsession with matters of scaling cardiovascular structures—
and the application of that theory to reference values for echocardiography.
