Left atrial appendage closure with the Ultraseal device: Initial experience and mid-term follow-up.

AIMS: Left atrial appendage (LAA) closure is considered an effective option in patients with non-valvular atrial fibrillation (NVAF) and contraindications to long-term oral anticoagulant (OAC) therapy. However, there are some concerns about safety of currently available devices. Our aim is to provide an initial assessment on feasibility and safety of the novel LAA closure Ultraseal device in patients with NVAF and contraindications to long-term OAC therapy. METHODS: Twenty-three consecutive patients with NVAF undergoing Ultraseal device implantation between July 2016 and February 2018 at two institutions were included. All patients performed transesophageal echocardiography and computed tomography angiography prior to LAA closure. RESULTS: Procedural success was achieved in all patients except two who experienced incorrect device deployment with incomplete LAA closure. Procedure duration halved from first to last procedure performed. The only periprocedural adverse events observed were a myocardial infarction and an in-hospital death due pneumonia. At mean follow-up (166 ± 80 days) all other patients were alive and free from major bleedings and ischaemic strokes. CONCLUSIONS: Our results suggest that the Ultraseal device is a feasible option for LAA occlusion. Notably, the learning curve in this registry was fast, paralleled by extremely low complication rates. These results should be considered hypothesis generating and larger studies are mandatory.

[Two-step strategy for the treatment of complex coronary artery disease and aortic stenosis in a patient with severely impaired left ventricular function]. / Strategia multistep per il trattamento di malattia coronarica complessa e stenosi aortica in un paziente con severa disfunzione ventricolare sinistra.

Coronary artery disease and aortic stenosis frequently coexist. The pathophysiology of both conditions is similar where atherosclerosis is the hallmark feature. Risk factors for aortic stenosis are also similar for coronary artery disease. The standard therapy in the past decades has been coronary artery bypass grafting and aortic valve replacement; however, with the introduction of transcatheter aortic valve implantation their management is probably going to shift towards a percutaneous strategy.

Symetis TF ACURATEneo™ Valve-in-Valve: A New Indication for Another Self-Expanding TAVI Prosthesis?

During the past decade there has been a major shift in the use of surgical bioprostheses. Consequently, due to the increasing age of the population there will be a major increase in the incidence of failure of these prostheses. While mortality associated with the re-replacement of surgical valve failures remains high, advances in transcatheter interventions have permitted the use of transcatheter valves in degenerative surgical bioprostheses. Herein is described the first use of the Symetis transfemoral ACURATEneo™ valve-in-valve procedure, together with details of the associated technical challenges.

Clinical outcomes of bioresorbable versus durable polymer-coated everolimus-eluting stents in real-world complex patients.

AIMS: The aim of this study was to evaluate the safety and efficacy profile of new-generation, SYNERGY everolimus-eluting stents (S-EES) as compared to XIENCE everolimus-eluting stents (X-EES) with a durable polymer coating in "complex patients". METHODS AND RESULTS: We included 2,001 consecutive patients treated with S-EES (n=400) or X-EES (n=1,601) at two Italian centres between May 2013 and May 2015. We used propensity score matching to obtain two cohorts of patients with similar baseline risk profiles. Patients were stratified according to baseline complexity based on the EVOLVE II trial exclusion criteria. The primary outcome was major adverse cardiac events (MACE), defined as the composite of all-cause death, myocardial infarction (MI), and target lesion revascularisation (TLR), at one year. Among 391 matched pairs of patients treated with S-EES or X-EES, we identified 253 (63%) as complex. At one-year follow-up, among "complex" patients, MACE rates did not differ between the S-EES and X-EES groups (9.9% vs. 9.5%, p=0.830, HR 1.04, CI: 0.72-1.48). Similarly, death, MI, and TLR, stratified for complexity, were comparable between S-EES and X-EES treated patients at one year. Of note, no definite ST was observed in either the S-EES or the X-EES cohort. CONCLUSIONS: New-generation S-EES with a bioresorbable polymer coating appear to be safe and effective irrespective of patient complexity as compared to X-EES.

Squamous cell carcinoma of unknown origin metastasising to the right atrium causing acute heart failure.

We describe a case of metastasis to the heart, which was initially suspected to be a myxoma, causing acute right heart failure. Emergency surgery was carried out by opening the right atrium and superior vena cava, and debulking the tumour in a piecemeal fashion, providing temporary relief of symptoms. The histology showed this to be metastatic squamous cell carcinoma possibly of head and neck origin. This is extremely rare, with few published cases. Full endoscopic and CT, including positron emission tomography CT, investigation of the head and neck was performed with no primary findings. Only two such cases of squamous cell carcinoma of unknown origin metastasising to the heart have been described, and, in both cases, the patients died within several weeks of diagnosis. This patient remains alive 2 months postoperatively and is receiving radiotherapy to the chest, but his prognosis remains poor.
