We examined the feasibility and reliability of a combined echocardiographic and right heart catheterization (RHC) approach for right ventriculo/arterial (R-V/A) coupling assessment in HF patients with dilated cardiomyopathy (D-CMP).
This is a single center, retrospective cross-sectional study. In 2016-17, for 6 months, we evaluated for eligibility 81 consecutive D-CMP patients afferent to "Niguarda Great Metropolitan Hospital" for RHC and echocardiography. All participants underwent the exams in the context of heart-transplant or advanced HF evaluation. Inclusion criteria were: 18 years old, given informed consent, D-CMP, New York Heart Association (NYHA) functional class II or III and reduced EF (≤ 35%). On the contrary, exclusion criteria were: missing the inclusion criteria and refused informed consent. The final sample consisted of 68 study participants (mean age 64±7 years, 82 % male).

R-V/A was achieved by computing the R-Elv/P-Ea ratio (Right ventricular elastance/Pulmonary arterial elastance). R-Elv was computed as PAPm / end-systolic area (ESA) of the right ventricle. P-Ea was obtained as (PAPm-PCWP)/ right ventricle stroke volume (R-SV).

Number of Participants with altered Right ventriculo/arterial (R-V/A) coupling over PAPm and Pulmonary Hypertension types
Significant correlations and augmentation over PAPm and Pulmonay Hypertension
Time frame: up to 24 weeks
Rate of agreement in Right ventriculo/arterial (R-V/A) coupling assessment
Two independent physicians, both experts in echocardiography, independently re-examined 40 studies, randomly selected from all the acquired echocardiographic images. In order to test the R-V/A coupling interobserver agreement
Time frame: up to 24 weeks
