Temporary balloon occlusion of atrial septal defects in suspected or documented left ventricular diastolic dysfunction: Hemodynamic and clinical findings

To review our experience with balloon testing prior to atrial septal defect (ASD) closure in adults with left ventricular (LV) diastolic dysfunction.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.Retrospective review of 27 patients age ≥ 50 years undergoing temporary ASD balloon occlusion between 2000 and 2018 for suspected LV diastolic...
