Table 1 Studies examining the incidence and clinical implications of preoperative right ventricular dysfunction in patients undergoing noncardiac surgery
From: Epidemiology of perioperative RV dysfunction: risk factors, incidence, and clinical implications
Study | Surgical population | N | AgeA Proportion male (%) | Definition of right ventricular dysfunction (all echocardiographic) | Incidence of preoperative RVD | Clinical significance |
|---|---|---|---|---|---|---|
 Kim et al. (2017) | Orthopaedic | 78 | 80.1 (9.1) 24.4% | RVGLS | RVGLS value below the normal range in 100% or patients | RVGLS independently predicted pulmonary complications (OR 2.09, 95% CI 1.047–4.151, p = 0.037) |
Chou et al. (2019) | Vascular | 108 | 72 [60-78] 75% | Normal vs. abnormal on visual inspection | 10 of 108 (9.3%) | RVD independently associated with post-op major cardiac complications (OR = 6.3, 95% CI 1.0–38.5, p = 0.046) Patients with RVD had a 50% longer LoS (IRR 1.5, 95% CI 1.2–1.8, p < 0.001 |
Joseph et al. (2021) | Renal transplant | 73 | 51.3 (14.2) 72.5% | Qualitative RV dysfunction and dilatation as adjudicated by the echocardiographer | RVD: 8 of 73 (11%) RV dilatation: 16 of 75 (21%) | RVD: Associated with composite of delayed graft function, graft failure, and all-cause mortality (p = 0.026) RV dilation: Associated with a significantly shorter time to all-cause graft failure (p = 0.03) and death (p = 0.048) |
Chou et al. (2021) | Abdominal ‘non-emergent open abdominal surgery’ | 122 | 65 [55-74]B 56 [45-68]B 45% | Normal vs. abnormal on visual inspection | 7 of 122 (5.7%) | RVD independent risk factor for all‑cause in‑hospital mortality (OR 18.9, 95% CI 1.8–201.7, p = 0.015) |
Meyer et al. (2023) | Vascular | 776 | 67 [60-75] 68% | Mild, moderate, or severe decrease in RV systolic function (no definition provided) | 85 of 776 (11%) | No association between RVD and major adverse cardiovascular events |
