Aims: The prognostic implication of left atrial (LA) dysfunction and left ventricular diastolic dysfunction (LVDD) in patients with coarctation of aorta (COA) is unknown. The purpose of this study was to determine whether LA dysfunction and LVDD were associated with mortality in COA patients. Methods and results: This is a retrospective review of adults (age ≥18 years) with repaired COA that underwent transthoracic echocardiogram (2000-18). LVDD was determined using the 2016 guidelines for LV diastolic function assessment, and LA dysfunction was assessed using LA reservoir strain. Of 721 patients, LV diastolic function could be determined in 635 (88%); and 414 (65%) had no LVDD, while 146 (23%), 53 (8%), and 22 (4%) had Grade I/II/III LVDD, respectively. The mean LA reservoir strain was 39 ± 11%, and patients were divided into quartiles: top quartile (reference group), mild LA dysfunction, moderate LA dysfunction, and severe LA dysfunction. Grade III LVDD (but not Grades I and II) was associated with death/transplant. On the other hand, there was an incremental risk of death/transplant across LA strain quartiles: mild LA dysfunction [hazard ratio (HR) 1.16, 1.04-2.06], moderate LA dysfunction (HR 1.75, 1.27-3.58), and severe LA dysfunction (HR 3.49, 1.88-7.16). Of 86 patients with indeterminate diastolic function, there was a trend towards a lower 5-year transplant-free survival in patients with LA dysfunction vs. normal LA function (83% vs. 91%, P = 0.06). Conclusion: LA dysfunction (but not LVDD) was associated with incremental risk of mortality and thus can be used for prognostication in all patients including those with indeterminate diastolic function.
