Figure 1. Angiography and optical coherence tomography (OCT) cross-sections of the eighth segmental branch of the left pulmonary artery, before and after balloon pulmonary angioplasty (BPA). A 6-French right Judkins guiding catheter was introduced to the ostium of the artery and 0.0014” coronary guidewire was placed distally in the vessel. Then optical coherence tomography (OCT) catheter (DragonFly, St. Jude Medical, USA) was advanced. Iodinated contrast was infused at a flow rate of 5 mL/s over 4 s at 400 psi of pressure and OCT images were acquired. Subsequently the vessel was accurately measured in several locations and the proper size of the balloon was selected. OCT images revealed the potential mechanisms of BPA: expansion of internal lumen of the artery was achieved by breaking the meshwork lesions inside the artery lumen and by compression of the boundary white thrombus. A 76-year-old female patient with chronic thrombo-embolic pulmonary hypertension (CTEPH) as a result of previous pulmonary embolism was admitted for balloon pulmonary angioplasty. Right heart catheterization showed mean pulmonary artery pressure of 61 mm Hg. Selective pulmonary angiography revealed subtotal occlusion of the A8 segmental branch of the left pulmonary INTERVENTIONAL CARDIOLOGY
