Incorrect prosthesis size has direct impact on patient outcome after transcatheter aortic valve implantation (TAVI) procedure. Currently, annular diameter, area or perimeter may be used for prosthesis size selection. The aim was to evaluate whether the use different annular dimensions would result in the selection of different prosthesis sizes, when assessed in the same TAVI-candidate during the same phase of a cardiac cycle. Fifty consecutive TAVI-candidates underwent retrospectively ECG-gated computed tomography angiography (CTA)...

OBJECTIVES: This study aims to establish parameters for identifying normal function for each of the 3 iterations of balloon-expandable valves and 2 iterations of self-expanding valves. BACKGROUND: Expected transthoracic echocardiographic Doppler-derived hemodynamic data for transcatheter aortic valves inform pre-implant decision-making and post-implanted monitoring of longitudinal valve function. METHODS: We collected the Echocardiography Core Lab measured mean gradients and effective orifice area (EOA) from discharge or 30-day echocardiograms from randomized trials; the PARTNER (Placement of Aortic Transcatheter Valves) trials for the balloon-expandable valves and the Medtronic CoreValve US Pivotal trial and Medtronic CoreValve Evolut R United States IDE Clinical Study for the self-expanding valves...

BACKGROUND: Intra-aortic balloon pumps (IABPs) have been used routinely since the 1970s. Recently, large randomized trials failed to show that IABP therapy has meaningful benefit, and international recommendations downgraded its place, particularly in cardiogenic shock. AIMS: The aim of this registry was to describe the contemporary use of IABP therapy, in light of these new data. METHODS: This prospective multicentre registry included 172 patients implanted with an IABP in 19 French cardiac centres in 2015...

An aortic aneurysm is defined as a balloon-shaped bulging of all three histologic components of the aortic vessel walls (intima, media and adventitia). This dilation results from vessel weakening owing to remodeling, i.e. due to cystic degeneration of the Tunica media (Marfan), progression of atherosclerosis or presence of a bicuspid aortic valve. The growth rate of the aortic diameter varies from patient to patient and may progress until the aneurysm ultimately ruptures. The role of hemodynamics, i.e. blood flow patterns, and shear stresses that are supposed to intensify during aneurysm growth are not yet fully understood, but thought to play a key role in the enlargement process...

Mitral annular calcification can pose a formidable surgical challenge in the setting of mitral valve replacement for mitral stenosis. Although there are reports of transapical valve-in-valve transcatheter mitral valve replacement in the setting of degenerated bioprosthetic mitral valve replacement, there is less experience with transcatheter mitral valve replacement for mitral annular calcification. This report describes a patient who previously received a transcatheter aortic valve replacement and then subsequently underwent a minimally invasive right thoracotomy for transcatheter mitral valve replacement with a successful result...

Acute right ventricle myocardial infarction (RVMI) is observed in 30-50% of patients presenting with inferior wall myocardial infarction and, occasionally, with anterior wall myocardial infarction. The clinical consequences vary from no hemodynamic compromise to severe hypotension and cardiogenic shock depending on the extent of RV ischemia. Areas covered: The pathophysiological mechanisms, diagnostic steps and novel therapeutic approaches of acute RVMI are described. Expert commentary: Diagnosis of acute RVMI is based on physical examination, cardiac biomarkers, electrocardiography and coronary angiography, whereas non-invasive imaging modalities (echocardiography, cardiac magnetic resonance imaging) play a complementary role...

INTRODUCTION: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been employed in refractory hemorrhagic shock patients. Since the optimal timing of arterial access remains unclear, we evaluated the pre-occlusion status of patients and elapsed time from the arrival to the hospital are associated with the survival outcomes in the REBOA patients. METHODS: From August 2011-December 2016, The DIRECT-IABO investigators registered refractory hemorrhagic shock patients undergoing REBOA from 23 hospitals in Japan...

PURPOSE OF REVIEW: Temporary circulatory support (TCS) with short-term mechanical circulatory support (MCS) devices is increasingly used as a salvage therapy for patients with refractory cardiogenic shock. This article provides an overview of current devices, their indications and management, and discusses results of recent case series and trials. RECENT FINDINGS: Percutaneous active MCS devices (Impella, TandemHeart…) and venoarterial extracorporeal membrane oxygenation (VA-ECMO) are utilized as a bridge to 'decision' that includes weaning after cardiac function recovery, transplantation, long-term MCS and withdrawal in case of futility...

Background: Very few data have been reported for ST-segment elevation myocardial infarction (STEMI) caused by unprotected left main coronary artery (ULMCA) occlusion, and very little is known about the results of this subgroup of patients who underwent primary percutaneous coronary intervention (PCI). The aim of this study was to determine the clinical features and outcomes of patients with STEMI who underwent primary PCI for acute ULMCA occlusion. Methods: From January 2000 to February 2014, 372 patients with STEMI caused by ULMCA acute occlusion (ULMCA-STEMI) who underwent primary PCI at one of two centers were enrolled...

Cardiac transplantation is the gold standard treatment for patients with advanced congestive heart failure that is refractory to maximal medical therapy. However, donor heart availability remains the major limiting factor, resulting in a large number of patients waiting long periods of time before transplantation. As a result, mechanical circulatory support devices have been increasingly used as a 'bridge' in order to sustain organ function and stabilise haemodynamics while patients remain on the transplant waiting list or undergo left ventricular assist device surgery...

BACKGROUND: Noncompressible truncal hemorrhage (NCTH) after injury is associated with a mortality increase that is unchanged during the past 20 years. Current treatment consists of rapid transport and emergent intervention. Three early hemorrhage control interventions that may improve survival are placement of a resuscitative endovascular balloon occlusion of the aorta (REBOA), injection of intracavitary self-expanding foam, and application of the Abdominal Aortic Junctional Tourniquet (AAJT™)...

As the primary treatment of aortic valve stenosis in children, surgical aortic valvotomy (SAV) and balloon aortic valvuloplasty (BAV) are widely used. With the similar early curative effect to BAV, SAV performs better in long-term follow-up. But the first choice for aortic valve stenosis is still controversial. These years, aortic valve repair is valued and different repair techniques have been reported and achieved good results. The complex repair techniques, as leaflet extension, leaflet replacement or valve reconstruction, are effective in treating diseased valves that cannot be repaired before...

BACKGROUND: The resuscitation of patients in shock is materially intensive and many patients are refractory to maximal therapy. We hypothesized that partial inflation of an intra-aortic balloon, termed Endovascular Perfusion Augmentation for Critical Care (EPACC), would minimize material requirements while improving physiologic metrics. METHODS: Swine underwent a 25% controlled bleed and 45 minutes of complete aortic occlusion to create a severe ischemia-reperfusion shock state...
