Medical balloon catheter: a key interventional tool for cardiovascular medicine treatment

1. Treatment of coronary artery stenosis: innovative application of balloon dilatation
The coronary artery is the main blood supply vessel of the heart, and its health status is directly related to the normal functioning of the heart. However, with the change of people's lifestyle and the acceleration of the aging process, coronary artery stenosis has become a common cardiovascular disease. When the coronary artery lumen is narrowed due to factors such as atherosclerosis and thrombosis, the blood supply to the myocardium will be seriously affected, leading to serious consequences such as angina pectoris and myocardial infarction.

The application of medical balloon catheters in the treatment of coronary artery stenosis is mainly reflected in balloon dilatation. The core of this technology is that doctors use vascular puncture technology to accurately deliver the balloon catheter to the lesion site. Subsequently, the balloon is inflated to expand and adhere to the narrow blood vessel wall. In this process, the expansion force of the balloon will push the plaque or thrombus on the blood vessel wall to the surrounding area, thereby effectively expanding the blood vessel lumen and restoring the normal blood supply to the myocardium.

Balloon dilatation not only has the advantages of less trauma and faster recovery, but also can significantly improve the treatment effect while reducing the patient's pain. In addition, with the continuous advancement of technology, the emergence of new balloon catheters such as drug-eluting balloons has further improved the accuracy and safety of treatment. These drug-eluting balloons can release drugs that inhibit cell proliferation while dilating blood vessels, thereby effectively preventing the occurrence of vascular restenosis.

2. Treatment of aortic stenosis: a new chapter in balloon dilatation
Aortic stenosis is another common cardiovascular disease that mainly occurs in the aortic valve orifice. When the aortic valve orifice is narrowed due to various reasons, the heart's pumping function will be seriously affected, leading to symptoms such as palpitations and dyspnea.

Similar to the treatment of coronary artery stenosis, the treatment of aortic stenosis is also inseparable from the use of medical balloon catheters. Through balloon dilatation, doctors can accurately deliver the balloon catheter to the narrow part of the aortic valve orifice. Subsequently, the balloon is inflated to push the narrowed valve tissue to the surrounding area, thereby expanding the valve orifice area and improving the heart's pumping function.

It is worth noting that balloon dilatation for aortic stenosis requires higher technical requirements and precision during the treatment process. Because the structure of the aortic valve orifice is complex and sensitive, the slightest carelessness may cause valve damage or complications. Therefore, when performing such treatment, doctors need to fully understand the patient's condition and valve structure characteristics, and choose the appropriate balloon catheter and treatment method to ensure the safety and effectiveness of the treatment.
