Left atrial strain (LAS), particularly left atrial reservoir strain (LASr), has recently been incorporated into contemporary guideline-based assessment of left ventricular diastolic function, representing its only established routine clinical application. Beyond this role, accumulating evidence identifies LAS as a sensitive marker of atrial mechanical dysfunction, capturing early alterations in reservoir, conduit, and contractile function. Reduced LAS is consistently associated with elevated left ventricular filling pressures and with increased risks of ischemic stroke, atrial fibrillation, adverse cardiac remodeling, and heart failure. These observations position LAS as a promising tool for refined risk stratification, early disease detection, and prognostic evaluation across a broad spectrum of cardiovascular conditions. However, outside diastolic function assessment, these applications remain investigational and are not yet validated for routine clinical use. Ongoing advances in speckle-tracking echocardiography, multimodality imaging, and artificial intelligence are expected to enhance the reproducibility and clinical integration of LAS. This paper provides a comprehensive review of the emerging role of LAS as a potential noninvasive sensitive biomarker for the early detection, risk evaluation, prognostic assessment, and therapeutic guidance of major cardiovascular events, specifically cardioembolic strokes, heart failure, cardiomyopathies, and coronary artery diseases.</p><p><b>Abbreviations:</b> ACM or AtCM, atrial cardiomyopathy; ACS, acute coronary syndrome; AF, atrial fibrillation; AI, artificial intelligence; ARVC, arrhythmogenic right ventricular cardiomyopathy; AUC, area under the curve; BMI, body mass index; CA, cardiac amyloidosis; CAD, coronary artery disease; CCT, cardiac computed tomography; CCTA, cardiac computed tomography angiography; CHF, congestive heart failure; CIS, cryptogenic ischemic stroke; CKD, chronic kidney disease; CMR, cardiac magnetic resonance; CRP, C-reactive protein; CRT, cardiac resynchronization therapy; CS, cryptogenic stroke; DCM, dilated cardiomyopathy; EAT, epicardial adipose tissue; ECG, electrocardiogram; ESE, exercise stress echocardiography; ESUS, embolic strokes of undetermined source; HCM, hypertrophic cardiomyopathy; HF, heart failure; HFpEF, heart failure with preserved ejection fraction; HR, heart rate; HTN, hypertension; ILs, interleukins; LA, left atrial; LAA, left atrial appendage; LAA MD, Left atrial appendage mechanical dispersion; LACI, LA coupling index; LACM, left atrial cardiomyopathy; LAEF, LA emptying fraction; LAGLS, reduced left atrial global longitudinal strain; LAS, left atrial strain; LAScd, LA strain conduit; LASct, LA contractile strain; LASr, Left atrial reservoir strain; LASTI, left atrial strain time ","PeriodicalId":16329,"journal":{"name":"Journal of interventional cardiology","volume":"2026 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/joic/6034327","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148386891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe coronary calcification remains a frequent cause of procedural difficulty and device delivery failure during complex percutaneous coronary intervention (PCI). Delivery of the atherectomy burr to the target lesion may be particularly challenging in the presence of limited guide support, proximal vessel tortuosity, or unfavorable coronary anatomy that restricts safe access to distal calcified segments. Guide extension catheters (GECs) are widely used to enhance guide support and improve coaxial alignment during complex PCI. However, their use in combination with RA represents an advanced and selectively applied strategy that is not routinely addressed in conventional atherectomy training and is often avoided because of concerns regarding device interaction and difficulties during burr delivery and retrieval. Despite increasing anecdotal use in complex PCI, the technical principles and procedural safety considerations of performing RA through GECs remain insufficiently described in the literature. This review provides a focused technical overview of RA performed through GECs. We summarize the rationale for this approach, describe key technical considerations including device compatibility and burr advancement strategies, and discuss practical measures to minimize procedural complications.
