Orthopnea and pulmonary hypertension. Treat the underlying disease

Abstract

We report the case of a patient with longstanding dyspnea upon reclining, who presented with severe right heart failure due to chronic alveolar hypoventilation. Bilateral diaphragmatic paresis was discovered. She recovered from her right ventricular failure with non-invasive mechanical ventilatory support. Keywords: Diaphragm dysfunction, Right heart failure
