OBJECTIVES AND BACKGROUND: Polymer coatings of drug-eluting stents (DES) may induce allergic reactions and inflammation, resulting in late-acquired stent malapposition (LASM) with the risk of stent thrombosis. This study evaluated, if biodegradable polymer (BP) reduces the incidence of LASM compared to permanent polymer (PP) after treatment with newer generation DES. METHODS AND RESULTS: Fifty patients with 59 lesions were randomized (2:1) to elective treatment with second generation PP-DES (n = 32, 39 stents), either Everolimus-eluting or Zotarolimus-eluting stents, or with BP-DES (Biolimus-eluting stents [BES]; n = 18, 20 stents) and underwent optical coherence tomography directly after implantation and after 1 year...

BACKGROUND: The concomitant presence of atrial fibrillation (AF) in the setting of Transcatheter Mitral Valve Repair (TMVR) represents a clinical challenge. Despite the high AF burden in patients presenting for the TMVR procedure, there are no studies that evaluate the impact of AF on in-hospital outcomes of TMVR in a nationally representative United States sample reflecting real practice. Therefore, we sought to study the outcomes of AF patients undergoing TMVR. METHODS AND RESULTS: The study included 1026 patients from the National Inpatient Sample (NIS) registry...

BACKGROUND: To date, there are no guidelines recommending a specific prophylactic antibiotic treatment in transcatheter aortic valve replacement (TAVR). The aim of this study is to evaluate clinical data after TAVR with different periprocedural antibiotic regimens. METHODS: In May 2015 the institutional rules for periprocedural antibiotic prophylaxis were changed from 3 days to 1 day. Thus, a total of 450 consecutive TAVR patients between February 2014 and June 2016 were classified into two intention-to-treat groups: patients receiving a 1-day Cefuroxime prophylaxis (N = 225); patients receiving a 3-day Cefuroxime prophylaxis (N = 225)...

In the recent years, ischemic brain injury related to embolization after transcatheter aortic valve replacement (TAVR) has received increased attention as new embolic protection strategies emerged to protect the brain. Diverse cerebral protection devices have been developed to reduce cerebral embolization during TAVR. These devices work through various mechanisms and are in different stages of clinical translation. This review provides the evidence-based review of peri-procedural stroke prevention during TAVR and summarizes currently available cerebral embolic protection devices...

Femoral and radial artery access continue to be the standard of care for percutaneous coronary interventions. Cardiac catheterization has progressed to encompass a wide range of diagnostic and interventional procedures including coronary, peripheral, endovascular, and structural heart disease interventions. Despite advanced technology to make these procedures safe, bleeding, and vascular complications continue to be a substantial source of morbidity, especially in patients undergoing large-bore access procedures...

BACKGROUND: Post-myocardial infarction (MI) ventricular septal defects (PIVSD) are an uncommon but life-threatening complication of acute MI. Although surgical closure has been the standard of care, mortality, and recurrence of VSD remain high even after emergent surgery. Transcatheter VSD closure (TCC) devices have become an alternative or adjunct to surgical closure. METHODS: Online database search was performed for studies that included adults with PIVSD who underwent medical treatment (MT) alone, surgical closure (SC) (early or late), and TCC (early, late, or for post-surgical residual VSD)...

AIMS: In 2017, Kiemeneij published a paper on distal trans-radial artery access for coronary angiography in 62 patients. This paper proposed several advantages to this method. Since this paper was published, several other papers have been published describing this technique, with less than 200 cases in total described. We performed a non randomized control study of left distal trans-radial access in patients undergoing coronary angiography in our center. METHODS: We prospectively identified patients presenting for coronary angiography to our center for enrolment in this study...

OBJECTIVES: We performed a meta-analysis of transcatheter mitral valve implantation (TMVI) for deteriorated bioprosthetic valves (valve-in-valve [VIV]-TMVI) and/or failed annuloplasty rings (valve-in-ring [VIR]-TMVI), comparing observed early (30-day) mortality with predicted operative mortality. BACKGROUND: It remains unclear whether VIV/VIR-TMVI reduces mortality as compared with redo MVS. METHODS: MEDLINE and EMBASE were searched current through 24 July 2018 using Web-based search engines (PubMed and OVID) to identify studies including ≥10 patients undergoing VIV/VIR-TMVI...

This article is a continuation of our previously published annual reviews of transcatheter aortic valve replacement (TAVR). In 2017, TAVR further established a foothold in the management of intermediate risk patients with the publication of SURTAVI trial. Randomized trials also addressed the use of cerebral protection during TAVR and single versus dual antiplatelet therapy after TAVR. Newer generation valve systems continued to be studied for their efficacy and safety. This paper summarizes the major studies published in 2017...

OBJECTIVES: To evaluate the effectiveness of the proximal optimization technique (POT) to prevent longitudinal stent elongation. BACKGROUND: The mechanism of stent elongation, which occurs after post-balloon dilation, is still unclear. METHODS: A total of 103 lesions treated with optical coherence tomography guided coronary intervention between May 2013 and November 2017 were retrospectively analyzed. Lesions were divided according to the circumferential degree of malapposition at the stent edge immediately after deployment into well-apposed group (<180°) and malapposed group (≥180°)...

AIM: Left atrial appendage occlusion (LAAO) is a technique for preventing thromboembolism in patients with atrial fibrillation and a high risk of irreversible bleeding. In some patients, a spontaneous iatrogenic transseptal leak (ITL) remains after LAAO. The aim of this study was to assess the correlation between ITL incidence and the results of cardiac function tests in patients who underwent LAAO. METHODS AND RESULTS: LAOO was performed in 62 consecutive patients using the Amplatzer Amulet...

OBJECTIVES: To evaluate solid embolization during transcatheter aortic valve implantation (TAVI) and correlate this with aortic valve calcification. BACKGROUND: There is a known stroke risk with TAVI, thought partly to be due to dislodgement of native aortic valve particles during implantation. However, to date there is little evidence that aortic valve calcification actually impacts embolic risk. METHODS: Transcranial Doppler (TCD) was performed on consecutive suitable patients undergoing TAVI, using hardware and software enabling differentiation between solid and gaseous emboli...
