BACKGROUND New generation transcatheter heart valves (THV) may improve clinical outcomes of transcatheter aortic valve implantation. METHODS AND RESULTS In a nationwide, prospective, multicenter cohort study (Swiss Transcatheter Aortic Valve Implantation Registry, NCT01368250), outcomes of consecutive transfemoral transcatheter aortic valve implantation patients treated with the Sapien 3 THV ...
The following are highlights from the series, Circulation: Cardiovascular Interventions Topic Review. This series summarizes the most important manuscripts, as selected by the editors, which have published in the Circulation portfolio. The studies included in this article represent the most noteworthy research in the areas of transcatheter aortic valve replacement and transcatheter aortic-valve...
The surgical and transcatheter coil closure of coronary arterial fistulas are described in the literature. We report our experience with the successful transcatheter closure of a coronary arterial fistula, arising from the left coronary artery and draining into the right ventricle, with the new Amplatzer duct occluder II device.

C oronary artery fistulas (CAFs) and pulmonary arteriovenous malformations (PAVMs) are relatively rare but clinically important cardiovascular abnormalities that may require percutaneous treatment. In most patients, the current preferred treatment for both lesions is transcatheter embolization using techniques that are well established in these two conditions. We present a review of CAF and PAV...
BACKGROUND The anatomy of septal defects can be complex and morphologically unpredictable. Balloon sizing of such defects may not be feasible, and an appropriately sized commercial occluder may not be available. Therefore, percutaneous transcatheter closure of such defects can be challenging because of an increased risk of complications. In this study, we have described the efficacy and safety ...
Transcatheter aortic valve replacement. Clinical, Doppler, and outcome data were prospectively collected on 639 patients who underwent transcatheter aortic valve replacement (TAVR) for symptomatic severe aortic stenosis (AS) in 2 Canadian centers (1). Compared with normal flow patients, 52.3% had low flow (stroke volume index <35 ml/m) and had increased 30-day all-cause mortality (11.4% vs. 5.9...
OBJECTIVES The aim of this study was to analyze the risk factors and mid-term outcomes associated with post-procedure heart blocks (PPHBs) after transcatheter closure of perimembranous ventricular septal defect (pmVSD). BACKGROUND The development of heart blocks remains a major challenge for transcatheter closure of pmVSD. METHODS Transcatheter closure of pmVSD was carried out in 228 patien...
Transcatheter mitral interventions have been developed to address an unmet need, and as alternatives to surgery in patients at high risk or considered inoperable. Beyond MitraClip therapy, alternative repair technologies are being developed to expand the armamentarium of transcatheter intervention. Recently, the feasibility of transcatheter mitral valve implantation in native non-calcified valv...
Preoperative transcatheter arterial embolization for hypervascular bone tumors is now widely accepted as a safe and effective procedure for reducing intraoperative blood loss and surgical morbidity. However, few studies have reported the use of preoperative transcatheter arterial embolization for nonspine bone metastases from hepatocellular carcinoma. The goal of this study was to assess the ef...
