Complex Coronary Interventions
Some patients with complex or heavily calcified coronary artery blockages may require advanced angioplasty techniques. These procedures can involve specialised devices and are selected based on the patient’s condition and clinical assessment. Dr. Sai Satish performs complex coronary interventions and serves as an international proctor, providing procedural training and guidance to other interventional cardiologists.
Below are some types of complex coronary interventions:
- Multi-Vessel Stenting: In cases where multiple coronary arteries are blocked, stents are placed in each affected vessel to restore blood flow.
- Left Main Stenting: The left main coronary artery supplies most of the heart muscle. Stenting this critical artery is a highly complex and technically demanding procedure.
- Chronic Total Occlusions (CTO): When a coronary artery is completely blocked for an extended period, specialized tools and techniques are used to open it and restore blood flow.
- Calcified Lesions: Heavily calcified blockages require special approaches, like rotablation, to break up the hardened plaque.
- Graft Vessel Stenting: Patients who have undergone coronary artery bypass grafting (CABG) may develop blockages in graft vessels, both venous and LIMA (left internal mammary artery). Stenting these vessels can help restore blood flow post-surgery.
Advanced Tools for Complex Angioplasty
Several tools enhance the precision and effectiveness of complex coronary angioplasties. Dr. Sai Satish’s expertise in using these advanced tools ensures better outcomes for patients with complicated heart conditions.
- Rotablation: A technique used in selected cases of heavily calcified coronary artery blockages. A specialised device with a diamond-coated burr modifies hardened plaque to help prepare the artery for balloon treatment and stent placement. Dr. Sai Satish performs rotablation when appropriate, based on clinical assessment.
- Optical Coherence Tomography (OCT): This imaging technology uses light waves to provide high-resolution images of the artery, helping to assess the plaque and ensure precise stent placement.
- Intravascular Ultrasound (IVUS): IVUS provides detailed cross-sectional images of the coronary artery, enabling a more accurate assessment of vessel size and plaque burden, which is essential for complex stenting.
- Intravascular Lithotripsy (IVL): For severely calcified lesions, IVL delivers controlled sonic pressure waves to fracture calcified plaque, making it easier to expand the artery with a stent.
- Impella: For patients with severely diseased hearts, an Impella device acts as a temporary mechanical pump, supporting the heart during high-risk procedures, such as unprotected left main angioplasty. Dr. Sai Satish’s extensive experience with Impella provides an extra level of safety for critically ill patients undergoing complex interventions.
Coronary Angioplasty
Coronary angioplasty is a minimally invasive procedure used to improve blood flow through narrowed or blocked coronary arteries. It usually involves a balloon and may include stent placement, and is generally performed under local anaesthesia. It may be recommended for selected patients with coronary artery disease or as an urgent treatment during certain heart attacks. Where appropriate, angioplasty may follow a diagnostic angiogram in the same session, based on clinical findings and informed consent.
In angioplasty, a balloon-tipped catheter is used to widen the narrowed artery. The balloon is inflated to push plaque against the artery wall, then removed, allowing improved blood flow. A small wire mesh tube, called a stent, is typically placed to keep the artery open after ballooning.
Dr. Sai Satish’s dedication to excellence and patient wellbeing drives his commitment to using these innovative techniques to help patients with advanced heart conditions achieve optimal outcomes, enabling them to lead healthier, more active lives.
