Electrocardiogram (ECG) and Atrial Appendage Doppler Discordance Is Common in Patients Undergoing Cardiac Surgery: Prospective Study
Authors' conclusion
A large minority of patients without a history of AF undergoing cardiac surgery have ECG/atrial appendage Doppler discordance, a setting that may promote thromboembolism in non-anticoagulated patients. Clinical parameters do not identify patients at increased risk for discordance.
Study context
- Population
- Patients undergoing coronary artery bypass graft (CABG), CABG and valve surgery, or isolated valve repair or replacement107 without history of atrial fibrillation (AF)
- Participants
- 124 patients
- Outcome
- Frequency of ECG rhythm vs LAA and/or RAA Doppler ejection phenotype (TEE) discordance
- Follow-up
- Intraoperative, before cardiopulmonary bypass
Methodological detailsIntraoperative surface ECG and TEE left atrial appendage (LAA)/RAA Doppler independently classified as sinus or AF
- Intraoperative surface ECG and TEE LAA/RAA Doppler independently classified as sinus or AF
