| Summary: | Abstract Background Dyspnoea is a common presentation to the casualties, attributed mostly to cardiopulmonary diseases. Approach to dyspnoea consists of initial acute management to ensure airway patency, respiratory support, and hemodynamic stability, followed by identification of the underlying disease for a definite management to reduce short-term inpatient morbidity and mortality, and rehospitalization in long term. Awareness of the patient’s pre-existing medical conditions is a crucial clue to guide the attending doctor to the primary cause. Dyspnea in chronic liver disease can be due to concomitant cardiopulmonary diseases as well as pulmonary vascular congestion or abnormality associated with portal hypertension such as hepatopulmonary syndrome. Case presentation A 59-year-old man presented with a syncopal attack associated with breathlessness after physical exertion. He had alcohol associated liver cirrhosis for 2 years with a 6-month duration of platypnea and reduced effort tolerance. His physical examination revealed a cyanosed man with normal blood pressure and heart rate, without evidence of systemic and pulmonary fluid congestions. Chest radiography and computed tomography showed no evidence of pulmonary embolism and parenchymal disease and a normal echocardiography ruled out any cardiogenic cause. A diagnosis of hepatopulmonary syndrome was made after the appearance of microbubbles over left atrium at fourth to fifth cardiac cycle demonstrated by a transthoracic contrast-enhanced echocardiography to suggest an extracardiac intrapulmonary shunt. Conclusions HPS is not an uncommon complication of chronic liver disease. Usual manifestation of HPS is platypnea which needs to be differentiated from orthopnoea associated with cardiopulmonary disease. Nevertheless, there is no effective therapeutic approach of HPS besides liver transplantation.
