A 48-year-old male developed a recurrent aortic-root pseudoaneurysm after surgical repair for acute dissection. Although the initial closure of the pseudoaneurysm was successfully managed by transcatheter endovascular occlusion and coiling utilizing a hybrid transapical and transfemoral approach, the pseudoaneurysm was recanalized after 3 months and a third-time surgical repair was required. The potential risk for recurrence of pseudoaneurysms should be considered when applying endovascular occlusion devices to treat aortic root anatomy...

Coronary artery fistulas (CAFs) are abnormal communications of coronary arteries whereby venous circuits bypass the normal capillaries within the myocardium. CAFs are rare, and most affected patients are asymptomatic. However, these fistulas are the most common coronary artery anomalies that can alter coronary hemodynamic parameters. Although most CAFs are asymptomatic in young patients, symptoms and complications become more frequent with increasing age. CAFs are characterized by variable clinical manifestations that are based on the size, origin, and drainage site of the fistula...

BACKGROUND:  Paravalvular aortic regurgitation (PVAR) remains a frequent postprocedural concern following transcatheter aortic valve replacement (TAVR). Persistence of flow turbulence results in the cleavage of high-molecular-weight von Willebrand multimers, primary haemostasis dysfunction and may favour bleedings. Recent data have emphasized the value of a point-of-care measure of von Willebrand factor-dependent platelet function (closure time [CT] adenosine diphosphate [ADP]) in the monitoring of immediate PVAR...

OBJECTIVES: To evaluate the feasibility of fully percutaneous closure using a novel collagen-based vascular closure device after transfemoral aortic valve replacement (TAVR). BACKGROUND: TAVR is utilized increasingly for the treatment of severe symptomatic aortic stenosis. Vascular complications related to access and closure dominate the adverse event profile of the procedure despite progressively reducing arteriotomy caliber. The advent of a novel collagen-based device (MANTATM ) and preliminary data suggest this could be used as a routine percutaneous closure device...

We demonstrate the usefulness of two- and live/real time three-dimensional transesophageal echocardiography in a procedure, which combined transcatheter mitral valve-in-valve deployment and paraprosthetic leak closure in the same setting using the less invasive transfemoral approach in an adult patient with bioprosthetic mitral valve degeneration. We also highlight the additive value of three-dimensional echocardiography over the two-dimensional technique.

Patent ductus arteriosus is a common congenital cardiac defect comprising 5-10% of all these defects in term neonates. Although open chest and video-assisted interruption are still in use, transcatheter occlusion has rapidly become the first choice for patent ductus arteriosus closure in the appropriate patient. Percutaneous closure of patent ductus arteriosus is widely done by transvenous approach guided by aortic access. We present the case of a 2 year old girl who underwent patent ductus arteriosus device occlusion with transvenous access only...

Matthew J Price
Resection of the left atrial appendage (LAA) to prevent recurrent arterial emboli in patients with atrial fibrillation was first suggested more than 60 years ago. Longer-term follow-up from randomized studies of the safety and efficacy of transcatheter LAA occlusion has recently been completed; data from large, observational cohorts are being reported. These recent data provide further insights into procedural safety with current techniques and the ability of LAA closure to reduce thromboembolic stroke compared with warfarin anticoagulation...

An 18-month-old male Akita Inu dog developed fever and lameness 8 months after successful transcatheter closure of a patent ductus arteriosus with an Amplatz Canine Duct Occluder (ACDO). Corynebacterium species were cultured from 3 blood samples. Echocardiography showed a vegetative process on the aortic valves. The dog died spontaneously 3 days after development of the initial signs. Necropsy confirmed the presence of bacterial ductal arteritis and myocarditis, and revealed an incomplete endothelialization of the intraductal metal implant...

Major vascular complications still occur in ~4.2% of transcatheter aortic valve replacement (TAVR) procedures. These complications are a major safety drawback of TAVR when compared to surgical aortic valve replacement (SAVR). Contemporary strategies designed to minimize and effectively treat vascular complications are of immense importance to a successful TAVR program. This review discusses strategies to optimize TAVR access and device choice along with TAVR access complication management. Iliac complications are less frequently encountered and can be managed effectively via the TAVR sheath over the TAVR wire employing ipsilateral proximal iliac balloon occlusion and endovascular repair...

Nowadays patent foramen ovale (PFO) closure is considered clinically beneficial and even cost-effective over medical therapy in secondary prevention of stroke due to paradoxical embolism. Areas covered: In this review, the authors discuss both anatomical and technical details and constructive concepts of current devices used for PFO closure. Expert commentary: Right atrial and interatrial septum anatomy is more complex than usually thought and a unique prosthesis that fits properly to all the possible morphologies is far from being designed...

Nearly one-half of patients with cryptogenic stroke have a patent foramen ovale (PFO). The dilemma of whether to close these PFOs percutaneously, in an effort to reduce the risk of recurrent paradoxical embolism, has been a matter of ongoing debate for more than a decade. Early randomized clinical trials failed to demonstrate a significant benefit of percutaneous PFO closure for secondary prevention of cryptogenic stroke in an intention-to-treat analysis. The long-term follow-up data from the RESPECT trial and 2 new randomized trials (CLOSE and REDUCE) have clarified these findings...
