Collateral Vessels

A 49-year-old man with CTEPH (pre-procedural mean pulmonary artery pressure: 36 mmHg) underwent balloon pulmonary angioplasty. Chronic total occlusion of the left inferior pulmonary artery trunk was observed. To evaluate the collateral vessels of the chronic total occlusion, 4D-CTA was performed. The examination was performed using a 256-row detector CT system using the test bolus tracking method. 4D-CTA showed the bronchial artery-to-left inferior pulmonary artery collateral supply, which was confirmed by a selective bronchial artery angiography. The patient’s symptoms improved with balloon pulmonary angioplasty of the other stenotic lesions. 4D-CTA can noninvasively evaluate the anatomy and hemodynamics of multiple systemic collaterals simultaneously. This technique can support interventions in systemic artery-to-pulmonary artery collaterals, such as embolization, and could be helpful in challenging balloon pulmonary angioplasty interventions for chronic total occlusion to identify vessel structures distal to the chronic total occlusion and collateral channels for a retrograde approach.

Novel Method

Adequate guide support is crucial for percutaneous coronary interventions complicated by unfavorable coronary artery anatomy, pronounced calcification, or the presence of chronic total occlusion. A clinical case presents a novel technique for guide support during stenting chronic coronary occlusion via transradial approach originally proposed in the TransRadial Ultra Support Technique trial.

Chronic Thromboembolic Disease

Balloon pulmonary angioplasty (BPA) is a novel technique for the treatment of chronic thromboembolic pulmonary hypertension. While cardiologists need no introduction to the concept of balloon angioplasty, BPA has its own particular challenges. This article aims to provide the reader with an overview of BPA, starting with an introduction to chronic thromboembolic disease (CTED), the standard management of chronic thromboembolic pulmonary hypertension (CTEPH), technical challenges faced when performing BPA and the evidence base supporting its use. The second part of the article will focus on the future of BPA, in particular the areas where research is required to establish an evidence base to justify the role of BPA in CTEPH and CTED treatment.

Is Failure

Objectives: Endovascular treatment of atheromatous chronic total occlusions (CTOs) of the lower extremity using the subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) method may fail due to inability to position the antegrade and retrograde wires in the same plane. Failed attempted SAFARI in three limbs, in two patients, was rescued using a gunsight technique. Material and Methods: Retrospective procedure database review revealed three procedures where an occlusion could not be crossed despite antegrade and retrograde access which were treated using a novel technique for percutaneous puncture through antegrade and retrograde loop snares (gunsight technique). Results: Three limbs in two patients (mean age: 64 years) were treated using the gunsight technique. All three CTOs were successfully crossed and dilated with angioplasty and/or stents. A positive clinical outcome was achieved in each of the three affected limbs. Conclusion: The gunsight technique can improve technical success of SAFARI in the treatment of CTOs for atheroocclusive disease when there is failure to cross the lesion with standard endoluminal or subintimal approaches.
