RESUMO
OBJECTIVE: A systematic review was performed to determine if the continuous laryngoscopy exercise test (CLE) has been used in the diagnostics of exercise dyspnea in adults with asthma, and whether inducible laryngeal obstruction (ILO) is found in those with asthma or with severe or difficult-to-treat asthma. DATA SOURCES: We used Scopus and PubMed databases. The articles published up to 13 August 2019 were considered. STUDY SELECTIONS: We excluded manuscripts that did not contain information about adult patients with asthma. We included six studies from 59 search results in Scopus and none from the 17 search results in PubMed. RESULTS: The articles included 455 study individuals. Of these, 229 (50.3%) had diagnosed asthma or were treated with asthma medication. Altogether 31/229 (13.5%) subjects with diagnosis of asthma or previous asthma treatment had exercise-induced laryngeal obstruction (EILO) as comorbidity. The CLE test was performed on 229 patients with asthma. The method was used only for differential diagnosis of exercise-induced dyspnea to confirm EILO. At least 10/455 (2.2%) out of the 455 subjects experienced adverse events. CONCLUSIONS: This systematic review revealed that only a small proportion of patients with asthma had undergone the CLE test to assess exercise-induced dyspnea. None of the selected manuscripts reported severity of asthma. Whether CLE provides a valuable diagnostic tool for patients with severe or difficult-to-treat asthma cannot be determined according to this review.

We report the case of a 61-year old patient with signs and symptoms of heart failure with mid-range left ventricular ejection fraction and moderate mitral regurgitation of mixed etiology (rheumatic heart disease, toxic and ischemic). The dynamic behaviour of the mitral regurgitation was revealed by an acute episode of pulmonary edema in the context of an abrupt elevation of blood pressure inducing an increase in left ventricular afterload. Dynamic mitral regurgitation must be considered in any patient with exercise dyspnea who has a moderate mitral regurgitation in resting conditions or in patients with repeated acute pulmonary edema without an obvious cause. Exercise stress echocardiography is the best diagnostic test to explore the dynamic behaviour of the mitral regurgitation. Surgery or percutaneous treatment may be proposed in severe cases.
Nous rapportons le cas d'une patiente de 61 ans présentant une insuffisance cardiaque à fraction d'éjection moyennement altérée et une insuffisance mitrale modérée d'étiologie mixte (rhumatismale, toxique et ischémique). Le caractère dynamique de cette insuffisance mitrale s'est manifesté par une aggravation brutale de celle-ci lors d'un à-coup hypertensif, avec élévation de la post-charge ventriculaire gauche, menant au développement d'un Ådème pulmonaire aigu. L'insuffisance mitrale dynamique est à considérer chez tout patient souffrant de dyspnée d'effort et qui présente une insuffisance mitrale considérée comme modérée dans les conditions de repos ou chez les patients présentant des Ådèmes aigus du poumon à répétition sans cause évidente. L'examen de référence pour explorer le caractère dynamique d'une insuffisance mitrale est l'échographie d'effort. La prise en charge de l'insuffisance mitrale sévère peut être chirurgicale ou percutanée pour les cas à haut risque chirurgical.
