Achieving an optimal surgical result in patients with major aortopulmonary collateral arteries (MAPCAs) requires a thorough preoperative evaluation of the anatomy and physiology of the pulmonary circulation. This review provides a detailed description of diagnostic catheterization in patients with MAPCAs, including a summary of catheterization techniques, an overview of commonly used terms, and a review of MAPCA and pulmonary artery angiographic anatomy.

BACKGROUND Long lesions are known to have worse outcomes following percutaneous coronary intervention (PCI), but there are limited data assessing the association between lesion length and clinical outcomes in PCI procedures undertaken in chronic total occlusions (CTO). METHODS AND RESULTS We formed a longitudinal cohort (2006-2018, n = 27,205) of stable angina patients who underwent PCI to CTO in the British Cardiovascular Intervention Society (BCIS) database. Clinical, demographical, procedural...

Background null The ACURATE neo™ is a novel, second-generation self-expanding supra-annular transcatheter heart valve (THV). The objective of this multi-centre registry is to assess the safety, clinical utility, and impact of 'learning-curve-experience' (LCE) on transcatheter aortic valve replacement outcomes in the United Kingdom (UK) and Ireland. null Methods null We prospectively collected data from seven ACURATE neo™ THV implanting centres (n = 484) between February 2016 and November 2020. W...

AIMS We evaluated the first in-human performance of a novel hybrid imaging catheter that permits simultaneous and co-registered acquisition of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) images. METHODS AND RESULTS A total of 17 patients undergoing planned percutaneous coronary intervention (PCI) were imaged between August 2018 and August 2019. Eleven patients with both pre- and post-PCI IVUS and OCT images were included in the offline image analysis. IVUS and OCT imag...

OBJECTIVES We aimed to evaluate the risk of procedural complications after TAVR using secondary radial access (RA) versus femoral access (FA) through a systematic review and meta-analysis of the published literature. BACKGROUND Transcatheter aortic valve replacement (TAVR) entails both large-bore arterial access for device delivery and secondary arterial access for hemodynamic and imaging assessments. It is unknown whether RA versus FA for this secondary access reduces the risk of procedural com...

OBJECTIVES We investigated the clinical efficacy of a paclitaxel-coated balloon (PCB) with a novel matrix coating and reduced drug concentration in comparison with a widely used PCB with iopromide excipient. METHODS We prospectively enrolled patients with restenosis in drug-eluting stents. All patients were treated with a novel low-dose PCB with citrate-based excipient (Agent PCB). Angiographic follow-up was scheduled at 6-8 months. Outcomes were compared against those of patients treated with i...

Background null Chronic total occlusion (CTO) lesions remain technically challenging for percutaneous coronary intervention (PCI). The introduction of a retrograde approach has allowed marked improvement in the success rate of CTO recanalization. Reverse controlled anterograde and retrograde sub-intimal tracking (reverse CART) is the predominant retrograde wire crossing technique and can be broadly classified into three categories: (1) conventional (2) contemporary and (3) extended. The present ...

OBJECTIVES We aimed to assess the advantages of using the retrograde approach as an initial strategy rather than as a rescue strategy for complex chronic total occlusions (CTOs). BACKGROUND Even for complex CTOs where a retrograde approach is deemed necessary, an antegrade approach is frequently used as an initial strategy in real-world practice. METHODS We evaluated 352 retrograde procedures for CTO conducted at our high-volume center between January 2007 and January 2019. Procedural efficiency...

Objectives null To investigate the safety and efficacy of the ALLEGRA valve in routine use. null Background null The ALLEGRA aortic valve is a self-expanding transcatheter heart valve (THV) with bovine pericardial tissue and was CE approved in March 2017. Its unique design was developed to provide low prosthesis gradients. null Methods null We analyzed patients receiving an ALLEGRA THV between May 2017 and March 2021 at our center for treatment of aortic valve stenosis or degenerated valve prost...

OBJECTIVES To compare incidence of forearm radial artery occlusion (RAO) and hemostasis characteristics between distal and conventional transradial approach (DRA and TRA, respectively). BACKGROUND DRA has the potential advantage of reducing RAO. DRA effectively reduces time-to-hemostasis, however its role on preserving flow in the radial artery (PF) during hemostasis and consequent impact on RAO remains speculative. METHODS Eight hundred thirty-seven patients with TRA were previously enrolled in...
