Coronary artery compression during intention to treat right ventricle outflow with percutaneous pulmonary valve implantation: Incidence, diagnosis, and outcome

Abstract

CC is accurately diagnosed during right-ventricular outflow tract interventions. We recommend an aortic root angiogram during dilation with a non-compliant balloon matching the diameter and length of the intended conduit implant.

Anatomy of the left main coronary artery of particular relevance to ablation of left atrial and outflow tract arrhythmias

“…The close relationship of the LMCA to the PA is highlighted by the potential for LMCA compression during percutaneous pulmonary valve implantation 24 and in patients with severe pulmonary hypertension. 25 This relationship also is important during ablation of premature ventricular depolarizations 26 and monomorphic 27,28 and polymorphic ventricular tachycardia 29 that arise from myocardium that extends into the PA beyond the inferior margin of the PSV.…”

Three dimensional rotational angiography for assessment of coronary arteries during melody valve implantation: introducing a technique that may improve outcomes

“…Our candidate selection rate for Melody valve implantation was 73%, which is somewhat lower than in previous reports (83%) [2]. We believe that the lower selection rate was the result of several factors: first, we evaluated a wider range of patients than those specified in the US Food and Drug Administration (FDA) labelling.…”

“…However, patients may be excluded because of the risk of coronary artery compression. Conventional two-dimensional angiography, including selective coronary artery angiograms, may not definitively demonstrate coronary artery compression during simultaneous right ventricular outflow tract (RVOT) balloon dilation because the lesion is usually proximal and may be masked by the catheter intubating the vessel [2–4]. Moreover, unsupported dilation of stenotic and calcified conduits may result in ruptures or tears requiring covered stents or urgent surgery [5].…”

Transcatheter valve-in-valve therapy: What does the pediatric cardiologist need to know?

“…This must be ruled out with a properly-performed balloon occlusion test as described above. On balloon compression testing,~6% of patients have been excluded for percutaneous pulmonary valve implantation (PPVI) [38]. There is a case report of late-presenting coronary compression with exercise due to dissection of the ostium of the right coronary artery (RCA) [39].…”
