Aims: Preliminary data on Sapien 3 valve (S3-THV) use for transcatheter aortic valve implantation have shown an increased permanent pacemaker implantation (PPMI) rate with respect to Sapien XT valve. Aim of this study was to investigate the role of S3-THV position in the left ventricular outflow tract (LVOT) on electrocardiographic changes suggestive of atrioventricular (ΔPR) and/or intraventricular (ΔQRS) conduction abnormalities and 30 days PPMI rate. Methods and results: Eighty-six consecutive patients treated with S3-THV were included in the study...

BACKGROUND: The transition from complete aortic occlusion during Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) can be associated with hemodynamic instability. Technique refinements and new technologies have been proposed to minimize this effect. In order to inform new techniques and technology, we examined the relationship between blood pressure and aortic flow during the restoration of systemic circulation following aortic occlusion at progressive levels of hemorrhage...

OBJECTIVES: Although current case-mix classifications in prospective payment systems were developed to estimate patient resource usage, whether these classifications reflect clinical outcomes remains unknown. The efficient management of acute heart failure (AHF) with high mortality is becoming more important in many countries as its prevalence and associated costs are rapidly increasing. Here, we investigate the determinants of in-hospital mortality and hospitalisation costs to clarify the impact of severity factors on these outcomes in patients with AHF, and examine the level of agreement between the predicted values of mortality and costs...

Intra-aortic balloon pump (IABP) is commonly used as mechanical support after cardiac surgery or cardiac shock. Although its benefits for cardiac function have been well documented, its effects on cerebral circulation are still controversial. We hypothesized that transfer function analysis (TFA) and continuous estimates of dynamic cerebral autoregulation (CA) provide consistent results in the assessment of cerebral autoregulation in patients with IABP. Continuous recordings of blood pressure (BP, intra-arterial line), end-tidal CO2, heart rate and cerebral blood flow velocity (CBFV, transcranial Doppler) were obtained i) 5 minutes with IABP ratio 1:3, ii) 5 minutes, starting 1 minute with the IABP-ON, and continuing for another 4 minutes without pump assistance (IABP-OFF)...

OBJECTIVES: : The aim of this study was to prove technical feasibility and document haemodynamic and clinical outcomes of transcatheter aortic valve implantation (TAVI) with the latest generation repositionable and retrievable Lotus™ transcatheter heart valve (THV) without prior balloon-aortic valvuloplasty (BAV). It has been demonstrated for self-expandable and balloon-expandable THV that implantation without prior BAV is not only feasible and safe but also results in lower fluoroscopy times and amounts of contrast agent while yielding non-inferior haemodynamic and clinical outcome...

Valve migration into the left ventricular outflow tract (LVOT) during transcatheter aortic valve implantation (TAVI) is a life-threatening complication. An 89-year-old female patient was admitted for TAVI due to severe symptomatic aortic stenosis. After deployment of a balloon-expandable prosthesis, the prosthesis had migrated into the LVOT. The prosthesis was reimpacted to the aortic annulus by a balloon-assisted recapture procedure. Immediately after recapturing the prosthesis with an oversized balloon, the patient's vital signs deteriorated due to acute aortic regurgitation (AR), and a prompt valve-in-valve (V-in-V) procedure allowed us to stabilize the patient's condition...

INTRODUCTION: Percutaneous balloon aortic valvuloplasty (BAV) has been limited by the risk of complications and restenosis. However, growing use of transcatheter aortic valve implantation (TAVI) has revived interest in this technique. We analyzed the current indications for BAV and outcomes in a single center. METHODS: Acute results and long-term outcomes were analyzed in a retrospective single-center registry of patients undergoing BAV between January 2013 and January 2016...

PURPOSE: The aim of this study was to report the safety of coronary rotational atherectomy (RA) in patients with severe aortic stenosis (AS). RA in the clinical setting seems challenging because coronary slow flow leads to hemodynamic instability. METHODS: Between October 2013 and May 2016, 1401 patients in the Optimized transCathEter vAlvular iNtervention (OCEAN) registry in Japan underwent transcatheter aortic valve implantation (TAVI). The primary study endpoint was procedural success, defined as residual stenosis <20% with final Thrombolysis in Myocardial Infarction flow 3...

Acute afterload mismatch after surgery for mitral regurgitation (MR) with transient left ventricular dysfunction is well known, but not described after transcatheter mitral valve repair with MitraClip, except in functional MR and cardiomyopathy. MitraClip to manage acute severe MR and cardiogenic shock has also been rarely reported. We report here a 77-year-old female who presented with acute severe degenerative MR from a flail posterior leaflet, with cardiogenic shock requiring intra-aortic balloon pump support...

The use of balloon aortic valvuloplasty (BAV) has increased with the development of transcatheter aortic valve implantation (TAVI) to medically optimize patients prior to procedure. It has been traditionally done by a retrograde approach via the femoral artery or an antegrade approach via the femoral vein. Large sheaths have been required with traditional balloons which require large vessel access. Use of a low profile compliant valvuloplasty balloon has been demonstrated to have adequate BAV results with smaller sheath sizes...

Cardiogenic shock in the context of acute ST-elevation myocardial infarction (STEMI) remains a challenge to manage and results in significant mortality and morbidity, cardiac arrest in this setting even more so. The increase in myocardial oxygen demand and consumption with the use of inotropes is recognised as increasing mortality. Alternatives include the intra-aortic balloon pump (IABP), which has yet to be shown to improve outcomes, and extracorporeal membrane oxygenation (ECMO), which requires super-specialised techniques not widely available...
