Noncompaction Cardiomyopathy: Issues, Contradictions, and Search for Effective Diagnostic Criteria. Literature Review. Part 1.

Active research of noncompaction cardiomyopathy (NCM) has been going on for more than 30 years. A significant amount of information has been accumulated that is familiar to a much larger number of specialists than in the most recent past. Despite this, numerous issues remain unresolved, ranging from classification (congenital or acquired, nosology or morphological phenotype) to the ongoing search for clear diagnostic criteria that separate NCM from physiological hypertrabecularity and secondary noncompaction myocardium with the background of existing chronic processes. Meanwhile, a high risk of adverse cardiovascular events in a certain group of people with NCM is quite high. These patients need timely and often quite aggressive therapy. This review of sources of scientific and practical information is devoted to the current aspects of the classification, extremely diverse clinical picture, extremely complex genetic and instrumental diagnosis of NCM, and the possibilities of its treatment. The purpose of this review is to analyze current ideas about the controversial problems of noncompaction cardiomyopathy. The material for its preparation is the numerous sources of databases Web Science, PubMed, Google Scholar, eLIBRARY. As a result of their analysis, the authors tried to identify and summarize the main problems of the NCM and identify the ways to resolve them.

Distal Radial Artery Access in Noncoronary Procedures.

Since the beginning of interventional cardiology and for decades, the femoral artery has been the access of choice for both diagnostic and interventional endovascular procedures. Due to an extensive evidence base accumulated over the last 20 years, the majority of interventional cardiologists around the world prefer classical radial artery access for both elective and emergency procedures. A similar trend has been observed for distal radial artery access over the last 5 years. Noncoronary endovascular surgery undergoes the same stages of improvement and optimization of access, but in a more accelerated way. The goal of this review is to analyze the literature on distal radial artery access in noncoronary procedures.

A narrative review of history, advantages, future developments of the distal radial access.

This article presents a historical excursus and a review of modern literature on distal radial access for interventional surgery, discussing the anatomical and physiological substantiation of the use of this access point in endovascular surgery, its advantages and disadvantages. The main considerations directly related to distal puncture, choice of instrumentation, hemostasis, possible complications, and prevention are analyzed. The major areas of interventional surgery (coronary, vascular, oncological, and neurointerventional), where the distal radial approach is actively used, are reflected and their characteristics are highlighted. In general, it has been shown that with the development of technology, improved manual skills, the widespread use of hydrophilic introducers, and modern sheathless guiding catheters, the vessel diameter, and puncture site are not decisive factors when choosing access for any type of intervention.
