Which cardiac chamber is most commonly affected in idiopathic cardiomyopathy (in swischuck) ?
LEFT VENTRICLE
Two forms of idiopathic cardiomyopathy (in swischuck):
- restrictive and
- congestive cardiomyopathies.
Compare them according to myocardial wall thickness.
“restricTHICK” and “congesTEEEEN (thin)”
The term “restrictive” results from the fact that the THICKENED myocardium fosters poor systolic filling of the left ventricle, and the
term “congestive” reflects the fact that the THINNED left ventricular myocardium is ineffective in expulsion of blood from the left ventricle, and passive congestion results.

- in the full-term infant
- patent ductus arteriosus closes within a few hours or days after birth.
*in the premature infant,
where hypoxic pulmonary disease is commonplace
- the ductus, being very sensitive to hypoxia, remains open
