Aims: To analyse reasons, timing and predictors of hospital readmissions after transcatheter aortic valve implantation (TAVI). Methods and Results: Patients included in the Bern TAVI Registry between August 2007 and June 2014 were analysed. Fine and Gray competing risk regression was used to identify factors predictive of hospital readmission within 1 year after TAVI with bootstrap analysis for internal validation. Of 868 patients alive at discharge, 221 (25.4%) were readmitted within 1 year...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

The optimal antithrombotic therapies for transcatheter aortic valve implantation (TAVI) and MitraClip implantation have not been well established. We conducted a narrative review from currently available studies between January 2002 and May 2016 to highlight the advantages and disadvantages of antithrombotic therapy use in cardiac catheter-based therapeutic techniques. Recently, these techniques have dramatically altered the approach towards valvular heart diseases management. The introduction into clinical practice, of TAVI for severe aortic stenosis and MitraClip for mitral regurgitation, has revolutionized interventional cardiology...

P Lancellotti, H Kulbertus
Aortic valve stenosis (AS) is the most commonly operated valvular heart disease in developed countries. Aortic valve replacement is the sole effective treatment of symptomatic patients. PARTNER-1 (Placement of AoRtic TraNscathetER Valves) has recently proved the efficacy of percutaneous aortic valve replacement (TAVI : Transcatheter Aortic Valve Implantation) in patients at high surgical risk, or inoperable. In the present article, we report and discuss the results of the PARTNER-2 study in intermediate risk patients...

BACKGROUND: Permanent pacemaker (PPM) placement occurs in 5-20% of patients after transcatheter aortic valve replacement (TAVR). Although predictors of pacemaker implantation have been established, features that predispose patients to pacemaker utilization on follow up have not been widely reported. METHODS: We performed a retrospective review of patients undergoing commercial TAVR between 2011 and 2016. We collated patients that underwent in-hospital PPM implantation and had a follow up of at least 3months...

BACKGROUND: Diastolic mitral regurgitation (DMR) results from atrioventricular conduction disturbances, acute aortic regurgitation, and/or marked elevation of left ventricular filling pressure. Generally benign, in some clinical circumstances DMR has presumed to result in hemodynamic decompensation. The aforementioned causes of DMR are frequently encountered in patients treated by transcatheter aortic valve replacement (TAVR) but its clinical significance in this setting has not been studied...

Mitral regurgitation is a common mitral valve dysfunction which may lead to heart failure. Because of the rapid aging of the population, conventional surgical repair and replacement of the pathological valve are often unsuitable for about half of symptomatic patients, who are judged high-risk. Transcatheter valve implantation could represent an effective solution. However, currently available aortic valve devices are inapt for the mitral position. This paper presents the design, development and hydrodynamic assessment of a novel bi-leaflet mitral valve suitable for transcatheter implantation...

Acquired causes of coronary fistulas are rare disorders and may develop following coronary atherosclerosis, infection, or trauma (iatrogenic). Iatrogenic coronary fistulas may be acquired secondary to surgical or nonsurgical interventions. We describe a case of an iatrogenic coronary artery-left ventricle fistula following mitral valve replacement surgery, presented with ventricular arrhythmia and heart failure. In a unique technique, we implanted three coils with the aid of a Scepter C balloon with inflation at the ostial portion of the left circumflex artery...

Transcatheter aortic valve implantation is an established alternative and less invasive procedure to replace heart valves in symptomatic aortic stenosis patients; however, severe, life-threatening complications still exist. Coronary artery occlusion is a primary complication. We report a case of left main coronary artery occlusion after transcatheter aortic valve replacement, which was ameliorated using a double stent implantation technique.
