Coronary Microvascular Dysfunction: A Common but Often Overlooked ConditionCoronary microvascular dysfunction is a common yet frequently overlooked condition, affecting millions of patients worldwide. In the United States alone, 3 to 4 million men and women exhibit signs or symptoms of myocardial ischemia without obstructive coronary artery disease. This condition predominantly affects women, and studies on women with ischemic heart disease but no coronary obstruction show that their annual rate of major adverse cardiovascular events is higher than in matched control groups. Patients with impaired coronary flow reserve or microvascular dysfunction face a 2 to 4 times greater risk of such events. Current anti-anginal drugs have limited efficacy, with over half of the patients continuing to experience symptoms, and there are currently no therapies that directly improve coronary flow reserve. The condition leads to high utilization of healthcare resources and treatment costs, with patients frequently hospitalized and undergoing numerous coronary examinations at rates and severity comparable to those with obstructive coronary artery disease.

For this reason, Johnson & (Shockwave) Create aHourglass ShapeAngina PectorisStent---Shockwave Reducer, the same as implanted into the coronary artery,Can narrow the coronary sinus,Optimize and redistribute oxygenated blood flow, thereby supporting and enhancing perfusion to alleviate angina symptoms.

A-Flux ReducerByWoven from nickel-titanium alloy, designed in an hourglass shape.Adopting SwiftCell design, its design features:

  • Variable Cell Structure
Optimized to immediately redistribute cardiac blood flow post-implantation;
  • Hourglass Shape
Design with a narrow middle and wide endsAiming to provide stable performance that can adapt to any type of physiological anatomical structure;
  • Shape Memory Materials
Designed to seamlessly fit with the coronary sinus for proper implantation and long-term clinical outcomes.
