Objective: To review our experience with balloon testing prior to atrial septal defect (ASD) closure in adults with left ventricular (LV) diastolic dysfunction. Background: ASD closure in patients with LV diastolic dysfunction may precipitate LV failure. Temporary ASD occlusion has been used in this scenario but data are limited. Methods: Retrospective review of 27 patients age ≥ 50 years undergoing temporary ASD balloon occlusion between 2000 and 2018 for suspected LV diastolic dysfunction or elevated LV end-diastolic pressure (LVEDP). Results: Median age was 72 years (IQR 66.7; 75.2). Atrial fibrillation was seen in 58% of patients, hypertension in 58%, and coronary artery disease in 26%; 52% were females. Median ASD size was 13 mm (10; 18) and Qp/Qs 1.8 (1.6; 2.2). Median LVEDP was 14 mmHg (12; 22); pulmonary artery wedge pressure (PAWP) 12 mmHg (9; 16.5) and left atrial pressure (LAP) 13.5 mmHg (8; 16.3). After a median of 5 min (3; 10) of balloon occlusion, patients with baseline LVEDP ≥15 mmHg had more significant increases in LVEDP (9 [6; 12] vs. 2 mmHg [0.5; 5]; p = 0.03) and LAP/PAWP (10.5 [8.3; 16.3] vs. 1.5 mmHg [−1.5; 3]; p = 0.0003) than those with baseline LVEDP <15 mmHg. None of those with a baseline LVEDP <15 mmHg had a LAP/PAWP >15 mmHg during balloon testing compared to 92% of patients with a baseline LVEDP ≥15 mmHg. Conclusion: LVEDP might be used to predict LAP post-ASD closure. Comorbidities typically associated with LV diastolic dysfunction are common in these patients and should be considered in their management.
