Spontaneous coronary artery dissection (SCAD) is a non-traumatic, non-atherosclerotic, dissection of the coronary artery wall, due to the presence of a subintimal hematoma or an intimal tear with the creation of a false lumen that compresses the true lumen and restricts or obstructs flow. SCAD is an unpredictable disease, which can have a fatal course in acute coronary syndrome. Results from randomized studies are lacking, however, in the therapeutic approach of SCAD clinicians are guided by the findings from observational studies. The therapeutic approach in acute coronary syndrome caused by SCAD is mainly based on the individual operator's decision.
Coronary angioplasty is a procedure used to widen blocked or narrowed coronary arteries, the main blood vessels supplying the heart. The term 'angioplasty' means using a balloon to stretch open a narrowed or blocked artery. However, most modern angioplasty procedures also involve inserting a short wire-mesh tube, called a stent, into the artery during the procedure. The stent is left in place permanently to allow blood to flow more freely (NHS Choices). This book is a complete guide to the practice of coronary angioplasty for practising cardiologists and trainees. Beginning with an introduction to the evolution of the technique and the fundamentals of stent design, each of the following chap...

Michał Łuczewski opowiedział historię Polski w sposób, w jaki jeszcze nigdy nie została opowiedziana. Piszą ją nie dominujące elity, ale przedstawiciele warstwy zmarginalizowanej: chłopi ze wsi Żmiąca w Beskidzie Wyspowym. Dzięki poprzednim monografiom tej wsi (Franciszka Bujaka z 1903 i Zbigniewa Wierzbickiego z 1963 roku), które uczyniły z niej najdłużej badaną miejscowość w naukach społecznych, a także dzięki wieloletnim poszukiwaniom samego autora udajemy się w pasjonującą podróż od średniowiecza po współczesność. I dowiadujemy się, jak Polacy stali się narodem i jak naród stał się katolicki. Książka ukazuje, jak polskie ideologie narodowe – od s...
The demographic shockwaves of the nineteenth and early twentieth centuries in Europe produced tremendous change in the national economies and affected the political, social, and cultural development of these societies. Migration historians have begun to connect the various European migratory streams during this period with transcontinental migration to North America. This volume contains empirical studies on German in-migration, internal migration, and transatlantic emigration from the 1820s to the 1930s, placed in a comparative perspective of Polish, Swedish, and Irish migration to North America. Special emphasis is placed on the role of women in the process of migration. By looking specifically at postwar Germany, Klaus J. Bade underscores the relevance of this history in a concluding essay.
Innovation in interventional cardiology extends well beyond coronary stenting. Most of new technical advances will be incorporated soon in our curriculum for training interventional cardiologists. At the same time, most currently accredited interventionalists will need to incorporate these new developments in their catheterisation laboratories. The issue facing these physicians today is how to gain experience in new techniques and what can be done to make their learning curve as short as possible. The aim of this work is to provide the reader with a book that is at the same time both clinical and yet practically oriented, covering interventional techniques of special interest to the interven...
Cardiologists must answer three important questions when evaluating and treating patients with a coronary artery stenosis. As a physiologist: "What is the effect of this stenosis on coronary blood flow and myocardial function?"; as a clinician: " Is this lesion responsible for the patient's symptoms?"; and finally as an interventionalist: "Will revascularization of this artery improve the patient?" Fundamentally, the answer to these questions can be given to a large extent by measuring coronary pressure. That is the rationale of writing this book. 1. 1 Historical overview. Andreas Gruentzig and most interventional cardiologists in the early days of PTCA, had the intuitive feeling that pressu...
