Evaluation of Novel Balloon Pulmonary Angioplasty Using Intravascular Ultrasound for Total Occlusion Lesions and Blood Flow in the Postprocedural Phase After Initially Unsuccessful Procedures

The authors evaluated the success rate of lesion passage using the precedent intravascular ultrasound technique for total occlusion lesions of pulmonary arteries and to evaluate the improvement in remote blood flow in cases of initially unsuccessful balloon pulmonary angioplasty.
