Clinical Correlates and Prognostic Value of Elevated Right Atrial Pressure in Patients With Hypertrophic Cardiomyopathy.
CONCLUSIONS: Elevated RAP in patients with HCM is associated with left-sided heart failure and is an independent predictor of all-cause mortality and new-onset AF. PMID: 29526913 [PubMed - as supplied by publisher]

Abnormal right ventricular-pulmonary artery coupling with exercise in heart failure with preserved ejection fraction
Conclusions In addition to limited LV reserve, patients with HFpEF display impaired RV reserve during exercise that is associated with high filling pressures and inadequate CO responses. These findings highlight the importance of biventricular dysfunction in HFpEF and suggest that novel therapies targeting myocardial reserve in both the left and right heart may be effective to improve clinical status.

Direct epicardial assist device using artificial rubber muscle in a swine model of pediatric dilated cardiomyopathy.
CONCLUSIONS: Use of a circumferential direct epicardial assistant device resulted in improvement in hemodynamic data in a dilated cardiomyopathy model. Although there is still a need for improvements in device components, the direct cardiac assist device may be a good alternative to recent heart failure device therapies.
