The end stage or burned-out phase is an uncommon but challenging clinical evolution of hypertrophic cardiomyopathy (HCM). The management of end-stage HCM is empirically based on the use of drugs approved for heart failure with reduced ejection fraction; however, cardiac transplantation often represents the best option to improve survival. In our case, we describe the use of sacubitril/valsartan as a 'bridge to transplant' in a patient with end-stage HCM. After introducing the drug, enhancements in functional capacity, a reduction in natriuretic peptides and an increase in left ventricular ejection fraction occurred. Given their improved volume of oxygen consumption (VO 2 ) peak and hemodynamic parameters, our patient was left off the waiting list for cardiac transplant and continues to be regularly followed-up with every 3 months.

Pregnancy exposes women with inherited cardiomyopathies to increased risk for arrhythmias and heart failure. In asymptomatic patients with inherited cardiomyopathies, pregnancy is generally well tolerated. Preconception evaluation, risk assessment and proper counseling by a team of experienced physicians are mandatory in managing women with inherited cardiomyopathies planning pregnancy. In this paper, we reviewed the clinical course, risk assessment and management during pregnancy of women with cardiomyopathies.

Natriuretic peptides (NPs) counter the effects of volume overload or adrenergic activation of the cardiovascular system. They are able to induce arterial vasodilatations, natriuresis and diuresis, and they reduce the activities of the renin-angiotensin-aldosterone system and the sympathetic nervous system. However, in addition to wall stress, other factors have been associated with elevated natriuretic peptide levels. Since 2000, because of their characteristics, NPs have become quantitative plasma biomarkers of heart failure. Nowadays, NPs play an important role not only in the diagnosis of heart failure, but also for a prognostic purpose and a guide to medical therapy. Finally, a new drug that modulates the NP system or recombinant analogs of NPs are now available in patients with heart failure.
