Which patients are candidates for lung transplantation? Indications for unilateral, bilateral, and heart-lung...

Single-lung transplantation, long successful in resolving interstitial lung disease, can now be used in COPD patients and shows promise in managing pulmonary hypertension. The bilateral procedure, which often avoids cardiopulmonary bypass, is preferred when chronic airway infection is present. Heart-lung transplants, now rare, are used when pulmonary hypertension is complicated by congestive cardiomyopathy or irreparable cardiac defects. Mechanical ventilation, prior cardiothoracic surgery, and corticosteroid use no longer constitute absolute contraindications to lung transplantation. The growing scarcity of donor organs is increasing waiting times; thus, earlier recognition of potential recipients is necessary.
