Assessment of Right Ventricular Function in Advanced Heart Failure

Completed

• Conditions: Dilated Cardiomyopathy; Heart Failure

• Registration Number: NCT03893760
• Lead Sponsor: ITAB - Institute for Advanced Biomedical Technologies

Brief Summary

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).

Detailed Description

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).
