An unusual cause of dyspnea diagnosed late in life: severe pulmonary hypertension resulting from isolated anomalous pulmonary venous connection.

摘要

A 67-year-old US military veteran was referred to our clinic for evaluation of progressive dyspnea on exertion over the previous 2 years. His medical history was significant for systemic hypertension, obstructive sleep apnea, and the absence of primary lung disease, significant tobacco use, or coronary artery disease. At the time of consultation, his peripheral blood oxygenation saturation was 85%, hepatojugular reflux and lower-extremity edema were noted, and 6-minute walk distance was 34 m.
