Optical Coherence Tomography Is Superior to Intravascular Ultrasound for Diagnosis of Distal-Type Chronic Thromboembolic Pulmonary Hypertension

Abstract

Figure 1. Representative images of pulmonary artery on (Left) optical coherence tomography (OCT) and (Right) intravascular ultrasound (IVUS) in a patient with chronic thromboembolic pulmonary hypertension. Typical lesions were clearly observed on OCT, which were apparently superior to IVUS. IMAGES IN CARDIOVASCULAR MEDICINE

Visualization of Complete Regression of Pulmonary Arterial Remodeling on Optical Coherence Tomography in a Patient With Pulmonary Arterial Hypertension

“…4,10, 11 In the present case we were able to demonstrate, with serial OCT observations, that pulmonary arterial remodeling in PAH could completely regress in response to adequate medical therapy, indicating another aspect of usefulness of OCT in the management of the disorder.…”

Multiple Beneficial Effects of Balloon Pulmonary Angioplasty in Patients With Chronic Thromboembolic Pulmonary Hypertension

“…The effectiveness and safety of BPA were also assessed by these 2 modalities after inflation (Figures 1C,D). 15 The BPA procedure was limited to a maximum of 2 lobes per procedure. The patients were monitored for possible reperfusion pulmonary edema for 1 day after BPA.…”

Effects of Balloon Pulmonary Angioplasty on Oxygenation in Patients With Chronic Thromboembolic Pulmonary Hypertension – Importance of Intrapulmonary Shunt –

“…15, 21 Targeted vessels were selected on the basis of comprehensive findings, including webs, bands, abrupt narrowing and complete obstructions, derived from angiography, 3D-reconstructd computed tomography and intravascular imaging modalities, including optical coherence computed tomography. 4,22, 23 Under continuous intravenous infusion of heparin (400 U/h), we used a soft-tipped 0.035-inch wire (Large Focus ® , Terumo, Tokyo, Japan) to selectively engaged a 6Fr guide catheter (Heartrail ® , Terumo) to the targeted vessels in a 6Fr long sheath (Large Focus Introducer ® , Terumo). We selected a balloon size based on the targeted vessel diameter measured by angiography and/or intravascular imaging modalities, including optical coherence tomography (St. Jude Medical, St. Paul, MN, USA) or optical frequency domain imaging (Terumo).…”
