To report on 2 rare cases of balloon-expandable transfemoral transcatheter aortic valve implantation, where a trapped balloon led to complications requiring acute intervention. Both patients were elderly with increased risk profile and had been discussed by the heart team. After standard positioning of the valves using a transfemoral approach, retrieval of the pusher before deployment of the valve was missed. In 1 patient, rapid pacing was continued, the balloon deflated, the pusher pulled back and the balloon repositioned and reinflated...

OBJECTIVES: Iliofemoral arteries have been the preferred access for transcatheter aortic valve replacement (TAVR). When these arteries are too small, calcified or tortuous, an alternative access must be considered. Transinnominate (TI) access is an extrathoracic approach that does not require manipulation of major neurovascular structures or the apex. The aim of this study is to evaluate the efficacy and safety of TI TAVR as an alternative access in patients with severe aortic stenosis not amenable to a transfemoral approach...

Aims: Evidence on the impact on clinical outcome of active mechanical circulatory support (MCS) devices in cardiogenic shock (CS) is scarce. This collaborative meta-analysis of randomized trials thus aims to investigate the efficacy and safety of percutanzeous active MCS vs. control in CS. Methods and results: Randomized trials comparing percutaneous active MCS to control in patients with CS were identified through searches of medical literature databases. Risk ratios (RR) and 95% confidence intervals (95% CI) were calculated to analyse the primary endpoint of 30-day mortality and device-related complications including bleeding and leg ischaemia...

BACKGROUND: There is an increasing trend towards shorter hospital stays after transcatheter aortic valve implantation (TAVI), in particular for patients undergoing the procedure via transfemoral (TF) access. Preliminary data suggest that there exists a population of patients that can be discharged safely very early after TF-TAVI. However, current evidence is limited to few retrospective studies, encompassing relatively small sample sizes. METHODS: The Feasibility And Safety of early discharge after Transfemoral TAVI (FAST-TAVI) registry is a prospective observational registry that will be conducted at 10 sites across Italy, the Netherlands and the UK...

AIMS: Videodensitometric assessment of aortography provides a periprocedural quantitation of prosthetic valve regurgitation (PVR) after transcatheter aortic valve implantation. We sought to compare the videodensitometric parameters of PVR severity to the regurgitation fraction (RF) in a controlled in-vitro setting. METHODS AND RESULTS: In a mock circulation system, a transcatheter balloon-expandable valve inserted at the aortic valve position was gradually deformed to induce different grades of paravalvular leakage and the RF was measured with a transonic flow probe...

Heyde syndrome describes the triad of aortic stenosis, acquired coagulopathy, and anemia due to bleeding from intestinal angiodysplasia. An 87-year-old man with iron deficiency anemia due to melena was admitted to our hospital. On examination, a systolic murmur was heard and echocardiography confirmed the presence of aortic stenosis. Esophagogastroduodenoscopy and colonoscopy were unremarkable. Capsule endoscopy and double balloon endoscopy revealed angiodysplasia throughout the small intestine. Laboratory investigations were significant for reduced plasma levels of high molecular weight von Willebrand factor multimers...

OBJECTIVES: The most commonly used accesses for transcatheter aortic valve implantation (TAVI) are the transfemoral (TF-TAVI) and the transapical (TA-TAVI) ones. There are concerns about TA-TAVI use in patients with reduced left ventricular ejection fraction (LVEF). The aim of this retrospective multicentre study was to compare the outcomes of TA-TAVI and TF-TAVI in patients with poor LVEF. METHODS: Patients with LVEF ≤35% were included in the analysis. Data were obtained from the Italian Transcatheter Balloon-Expandable Registry (ITER), which enrolled patients undergoing TAVI with the Sapien bioprosthesis in 33 national centres...

The intra-aortic balloon pump (IABP) has been the most commonly used mechanical circulatory support device for nearly five decades. In theory, the IABP can increase the blood and oxygen supply of the coronary artery by increasing the diastolic pressure in the aortic root when the balloon is inflated and reduce left ventricular afterload by rapidly deflating the balloon during the systolic phase. Therefore, some researchers put forward the idea of preoperative prophylactic use of an IABP, which has been frequently performed in high-risk patients undergoing elective percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG)...

BACKGROUND: Transcranial Doppler ultrasound is a standard screening tool for vasospasm after subarachnoid hemorrhage. Prevention of vasospasm-induced delayed cerebral ischemia after subarachnoid hemorrhage depends on optimization of cerebral perfusion pressure, which can be challenged by neurogenic stress cardiomyopathy. Intra-aortic balloon pumps have been utilized to augment cerebral perfusion, but they change the transcranial Doppler waveform, altering its interpretability for vasospasm screening...
