Atrial septal defect in adults is associated with airway hyperresponsiveness

Abstract: Objective The association between secundum atrial septal defects (ASD) and asthma‐like dyspnea with consequent long‐term pulmonary inhalant use, is poorly understood in adult ASD patients. Airway hyperresponsiveness is suggested to be the underlying mechanism of cardiac asthma from mitral valve disease and ischemic cardiomyopathy. We hypothesized that airway hyperresponsiveness may also be found in adult ASD patients. Our aim was to study airway responsiveness in adult ASD patients before percutaneous closure … Show more

“…The -81%) prevalence of airway hyperresponsiveness in adult patients, which remained unchanged after device closure. 9 Therefore, the present study results are supportive evidence of irreversible, possibly ASD-associated pulmonary function impairment in a subgroup of repaired adults, requiring the use of pulmonary inhalants for obstructive airway disease.…”

“…Older subjects with ASD should be screened for respiratory elements in suspected cases and treated appropriately. This has the double benefit of symptomatic improvement and reduction in the PAH and associated challenges in device closure also found in the present study [22,23].…”

“…The ASD can increase the hyperresponsiveness of the airway in up to 63% of the patients. COPD can partly contribute to pulmonary hypertension [22]. A significant reduction in the COPD symptoms was found in up to 80% of patients with initial COPD symptoms.…”

“…For example, there is a high prevalence of airway hyperresponsiveness in patients with atrial septal defects (ASD), and it is suggested that airway hyperresponsiveness may be a possible mechanism for recurrent attacks of CVA. Unlike bronchial asthma, 11 asthma-like symptoms associated with ASD are not necessarily experienced every few hours or days, but can be progressive [ 11 ]. This better understanding of ASD-associated dyspnea could potentially prevent delays to the treatment of unrepaired ASD.…”
