A New Definition of Acute Myocardial Infarction – Changing Perspectives in Acute Cardiac Care

<abstract xmlns="http://www.w3.org/1999/xhtml"> Patients with acute myocardial infarction (AMI) complicated with cardiogenic shock (CS) present one of the highest mortality rates recorded in critical care. Mortality rate in this setting is reported around 45-50% even in the most experienced and well-equipped medical centers. The continuous development of ST-segment elevation acute myocardial infarction (STEMI) networks has led not only to a dramatic decrease in STEMI-related mortality, but also to an increase in the frequency of severely complicated cases who survive to be transferred to tertiary centers for life-saving treatments. The reduced effectiveness of vasoactive drugs on a severely altered hemodynamic status led to the development of new devices dedicated to advanced cardiac support. What’s more, efforts are being made to reduce time from first medical contact to initiation of mechanical support in this particular clinical context. This review aims to summarize the most recent advances in mechanical support devices, in the setting of CS-complicated AMI. At the same time, the review presents several modern concepts in the organization of complex CS centers. These specialized hubs could improve survival in this critical condition.</abstract>

A Long-Forgotten Tale: The Management of Cardiogenic Shock in Acute Myocardial Infarction

<abstract xmlns="http://www.w3.org/1999/xhtml">Transcatheter aortic valve implantation (TAVI) is an effective treatment option for patients suffering from symptomatic, severe aortic valve stenosis. Previously, only patients with prohibitive or high surgical risk were TAVI candidates; however, current guidelines already recommend TAVI as a treatment alternative for patients with intermediate surgical risk. Multidetector computed tomography (MDCT) has gained great importance in the periprocedural assessment of patients who undergo TAVI. Due to the three-dimensional image visualization, MDCT allows the evaluation of anatomical structures in a more comprehensive manner compared to echocardiography, the traditional tool used in TAVI patient work-up. By providing accurate measurements of the aortic root, MDCT helps to avoid potential patient-prosthesis mismatch throughout transcatheter valve sizing. Moreover, MDCT is also a feasible tool for access route evaluation and to determine the optimal projection angles for the TAVI procedure. Although the routine MDCT follow-up of patients is currently not recommended in clinical practice, if performed, it could provide invaluable information about valve integrity and asymptomatic leaflet thrombosis. Post-procedural MDCT can provide details about the position of the prosthesis and complications such as leaflet-thrombosis, aortic regurgitation, coronary occlusion, and other vascular complications that can represent major cardiac emergencies. The aim of the current review is to overview the role of MDCT in the pre- and post-procedural assessment of TAVI patients. In the first part, the article presents the role of pre-TAVI imaging in the complex anatomical assessment of the aortic valve and the selection of the most appropriate device. The second part of the review describes the role of MDCT in patients who underwent TAVI to assess potential complications, some of them leading to a major cardiovascular emergency.</abstract>

Role of Multidetector Computed Tomography in Transcatheter Aortic Valve Implantation – from Pre-procedural Planning to Detection of Post-procedural Complications

<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this study was to investigate the association between left ventricular remodeling, atrial fibrillation (AF), and the severity of ventricular tachycardia (VT) in patients with ventricular rhythm disturbances admitted in a level 3 facility of acute cardiac care. Material and Methods: The RHYTHM-ACC registry was a single-center observational study, including 150 consecutive patients with sustained or non-sustained ventricular tachycardia (sVT and nsVT, respectively) admitted in an intensive cardiac care unit (ICCU), separated in: group 1 - 29 patients (21.01%) with dilated cardiomyopathy (DCM), and group 2 - 109 patients (78.99%) with normal ventricular performance. We investigated the difference between clinical characteristics of patients with sVT versus those with nsVT in each study group, and the association between AF and different forms of ventricular arrhythmia in 38 (25.33%) patients with AF and 112 (74.66%) patients in sinus rhythm. Results: There were no significant differences between the study groups with respect to type of ventricular arrhythmia: sVT (46.87% vs. 36.44%, p = 0.2), nsVT (43.75% vs. 55.93%, p = 0.2), or ventricular fibrillation (VF) (9.37% vs. 7.62%, p = 0.7). However, patients with DCM presented a significantly higher incidence of AF (43.75% vs. 20.33%, p = 0.01) and bundle branch block (37.5% vs. 11.86%, p = 0.0007). VF occurred more frequently in patients with AF compared to those in sinus rhythm (18.42% vs. 4.46%, p = 0.006). Multivariate analysis identified the co-existence of AF (OR = 4.8, p = 0.01) and the presence of a bundle branch block (BBB) (OR = 3.9, p = 0.03) as the most powerful predictors for the degeneration of VT into VF in patients admitted with sVT or nsVT in an ICCU unit. Conclusions: In patients with any type of VT admitted in an ICCU, the presence of ventricular remodeling is associated with a higher incidence of AF and conduction abnormalities, but not with a more severe pattern of ventricular arrhythmia. At the same time, AF and BBB seem to represent the most powerful predictors for degeneration of VT into VF, independent of the type of VT.</abstract>

Atrial Fibrillation, Ventricular Arrhythmia, and Left Ventricular Remodeling in the ICU – First Results of the Single- Center RHYTHM-ACC Registry

<abstract xmlns="http://www.w3.org/1999/xhtml">Sudden cardiac death in children is one of the most devastating conditions that can be encountered in acute cardiac care. Intracardiac device therapy, providing prompt and effective treatment in malignant ventricular arrhythmia or in severe conduction abnormalities, is a promising tool to reduce the incidence of this fatal condition. However, the implementation of device-based therapy in the pediatric population is currently limited by the lack of clinical studies on large number of subjects. As a result, indications for device therapy in pediatric patients are still unclear in many circumstances. There are also several particularities related to device implantation in pediatric age, such as the somatic growth leading to a mismatch between chamber size and lead length, or the difficulties of implantation technique in children with small body weight. This study aims to present an update on the current advantages and limitations of device-based therapy for treating severe malignant arrhythmia or conduction disorders in children at risk for sudden cardiac death.</abstract>

Journal of Cardiovascular Emergencies

 The Journal of Cardiovascular Emergencies aims to publish top quality papers related to acute conditions in any cardiovascular pathology. The journal will mainly focus on recent advances in the field of diagnosis and treatment of the most common causes of cardiovascular emergencies, including acute coronary syndromes, acute heart failure, acute aortic diseases, pulmonary embolism, peripheral arterial diseases or cardiac arrhythmia. Interdisciplinary approaches will be extremely welcomed, presenting new advances in the approach of different other pathologies (i.e. stroke) from the cardiovascular perspective.  The Journal of Cardiovascular Emergencies will publish high-quality basic and clinical research related to these topics, in a common approach that will integrate the clinical studies with the pre-clinical work dedicated to discovery of new mechanisms involved in the development and progression of acute cardiovascular conditions.  Especially in the case of acute coronary syndromes, the journal will try to provide the entire cardiology community with the perspective of the regional cardiology networks in Central and Eastern European countries, reflecting the regional model of care in cardiovascular acute conditions.  The journal will primarily focus on publishing original research papers, but also other types of materials (such as review articles, case reports, state of the art papers, comments to editor, etc) will be extremely welcomed.
