| Popis: | Purpose Right atrial waveform provides diagnostic and clinical information in heart failure patients. Notably, the y-descent (Figure 1A) may provide information about right ventricular systolic and diastolic function . We aimed to investigate the clinical implication of right atrial waveform in LVAD patients. Methods Patients underwent right heart catheterization (RHC) at 6 months following LVAD implantation and were followed for 1 year afterwards. Impact of a deep y-descent (>3 mmHg) on echocardiographic RA and RV function and clinical outcomes were investigated. Results 56 LVAD patients (mean age 56.2 years, 77% male) underwent RHC. Patients with post-LVAD deep y-descent (N = 22 [39%]) had increased right ventricular size and worse right ventricular function (Table 1A). The patients with deep y-descent had higher rates of GI bleeding (1.10 vs. 0.32 event/year), stroke (0.28 vs. 0.0 event/year), and heart failure readmissions (0.57 vs. 0.12 events/year) compared to those without (p Conclusion Deep y-descent of the right atrial waveform during LVAD support is associated with impaired right ventricular function and worse clinical outcomes. |
