Interventional Cardiology is a subspecialty of cardiology that focuses on diagnosing and treating heart conditions through catheter-based procedures. It allows cardiologists to perform complex interventions using minimally invasive techniques, typically involving the insertion of a catheter into the blood vessels, which is guided by imaging(such as X-ray or ultrasound). This field has revolutionized the treatment of cardiovascular diseases, reducing the need for open-heart surgery and leading to faster recovery times for patients.
