What is this paper about
Routine preoperative echocardiography before noncardiac surgery often adds little in unselected patients, with low actionable yield and weaker prediction than biomarkers such as NT-proBNP. The full read shows where echocardiography still matters, when stress echo or targeted TTE is justified, and how clinicians can move from routine imaging to smarter, risk-guided perioperative assessment.

Abstract: This scoping review aims to systematically map and synthesize the available evidence on the utility, prognostic value, and clinical impact of routine preoperative echocardiography in adults undergoing noncardiac surgery, with a focus on its role in risk stratification, prediction of perioperative adverse events, and alteration of perioperative management compared to clinical risk indices and cardiac biomarkers. The review uses 72 references and builds its evidence map from 154 original studies with 5326296 total participants/sample observations (topic-deduplicated ΣN). The mapped evidence indicates that routine resting preoperative echocardiography in unselected noncardiac surgery populations yields a low prevalence of actionable findings (0.8–9%) and rarely alters perioperative management, while NT-proBNP consistently outperforms transthoracic echocardiography for predicting cardiovascular events (c-statistic 0.748 vs 0.579–0.589). Across study designs, the dominant signal supports a selective, biomarker-guided strategy rather than indiscriminate imaging, with stress echocardiography and targeted TTE reserved for higher-risk cohorts in whom specific findings independently predict mortality. The literature also highlights that more than one in four preoperative echocardiograms are ordered for rarely appropriate indications, reinforcing concerns about low-value care. Given the predominance of observational data, future randomized and de-implementation trials are needed to confirm whether a biomarker-first, selectively imaged pathway improves outcomes and resource use compared with routine echocardiography.
