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)...

BACKGROUND: National registries have provided data on in-hospital outcomes for several cardiac procedures. The available data on in-hospital outcomes and its predictors after pericardiocentesis are mostly derived from single center studies. Furthermore, the outcomes after pericardiocentesis for iatrogenic pericardial effusion and the impact of procedural volume on in-hospital outcomes in the United States are largely unknown. METHODS: We used national inpatient database files for the years 2009-2013 to estimate the inpatient outcomes after pericardiocentesis in all-comers and in the subgroups with iatrogenic effusion...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) for low gradient (LG) severe aortic stenosis (AS) with preserved left ventricular ejection fraction (LVEF) remains an area of clinical uncertainty. METHODS: Retrospective review identified 422 patients who underwent TAVR between September 4, 2014 and July 1, 2016. Procedural indication other than severe AS (n = 22) or LVEF <50% (n = 98) were excluded. Outcomes were defined by valve academic research consortium two criteria when applicable and compared between LG (peak velocity <4...

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: The aim of the study was to evaluate the occurrence of hand ischemia in patients with radial artery occlusion (RAO), using the contralateral hand as control. BACKGROUND: Radial artery occlusion is a common complication (6%) after transradial access (TRA) but rarely leads to major ischemic events due to the collateral perfusion of the hand. However, it has been reported that RAO can become symptomatic, possibly as a consequence of hand ischemia. To evaluate the existence of exercise induced hand ischemia in patients with RAO, we initiated the present study...

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)...

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 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...

BACKGROUND: Open cell stents are frequently used in interventional therapy of congenital heart disease. Overstenting of vessel branches may necessitate strut dilation. METHODS AND RESULTS: The strut size achievable in Bard Valeo and Cook Formula stents, and the pressure necessary to fracture struts was assessed. In addition, a self expanding stent (Optimed SinusflexDS) was also tested. With the original balloon at nominal pressure, in Valeo stents side struts could be dilated to approximately 90% of the nominal stent diameter, in Formula stents to approximately 80%...
