Dominating factor of development of functional mitral insufficiency in patients with ischemic heart disease and dilated cardiomyopathy is deformation of atrioventricular valve leaflets due to traction by chordae apparatus. In patients candidates for left ventricular reconstruction because of its postinfarction aneurism the problem of preexisting or recurrent dysfunction of mitral valve acquires special value as operation itself implies surgical ventricular remodeling and therefore change of mitral valve geometry. Supplementation of the volume of surgical intervention with resection of chordae responsible for impaired coaptation of mitral valve leaflets in some cases appears to be effective and simple method of correction of mitral insufficiency.

Inhospital treatment of patients with heart failure (HF) can cause changes of N-terminal pro-brain natriuretic peptide (NT proBNP) levels. It has not been established yet which NT proBNP value (before or at height of treatment activation) is closer related to prognosis of unfavorable outcome after discharge. ⋯ In this group of patients hospitalized because of worsening HF predischarge but not admission NT-proBNP level was independently related to risk of death during next 6-12 months.
