Summary

Balloons, assisted by stents, are the established tools to widen coronary stenoses. This applies to chronic coronary disease as well as to acute coronary syndromes. The goals of good balloon performance are effective dilatation (in terms of a sustained result), patient safety, promptness of action and efficiency. The earlier experience and research of pioneers is now standard knowledge imparted in educational programmes. It should be kept in mind, however, that a balloon is always part of a catheter system, namely a foreign body interacting with tissues and blood fluid. The materials, polymers and metals, also interact with each other, sometimes in an unpredictable manner. The use of balloon catheters therefore requires clear knowledge of the disease being treated and also of the technical and biological interactions with intracoronary equipment.

Introduction

Balloon catheters are the basis for everyday catheter laboratory work. The construction of standard products is well established and the principal function of the balloon has not changed much in the last 15 years. The materials, however, are better now, and stents and drugs have been added which aim to stabilise the dilatatory effect of the balloon, such that nearly every PCI is now finished with a stent.
