[Primary balloon dilatation in every coronary stenosis?]

Area of Science:

• Interventional Cardiology
• Cardiovascular Medicine

Background:

• Coronary balloon angioplasty revolutionized cardiology, with continuous technical improvements in dilatation catheters over 18 years.
• Despite new devices, balloon catheters remain the dominant instrument for coronary angioplasty.
• The increased use of coronary angioplasty is driven by earlier detection and more frequent invasive treatment of coronary artery disease.

Purpose of the Study:

• To evaluate the role of balloon angioplasty and newer devices in contemporary interventional cardiology.
• To assess the cost-efficiency and simplicity of coronary angioplasty procedures.
• To determine the optimal strategy for using new devices in relation to balloon angioplasty.

Main Methods:

• Review of technical advancements in coronary angioplasty devices.
• Analysis of trends in the frequency and patient population of coronary angioplasty procedures.
• Evaluation of indications for new interventional devices versus balloon angioplasty.

Main Results:

• Balloon angioplasty catheters have seen significant refinements and remain the primary tool.
• Coronary artery stents are the only device proven to be significantly advantageous.
• Newer devices have limited utility, primarily for complications like dissection (stents) or unpassable stenoses (rotablator, laser).

Conclusions:

• Balloon angioplasty should be the first-line treatment for most coronary situations, both simple and complex.
• Newer devices should be reserved for cases where balloon angioplasty fails.
• The trend towards simpler, more cost-efficient angioplasty favors the continued primary use of balloon catheters.
