When Failure Sets the Stage for Success: Unstable Angina Stabilized with Advanced LAD CTO-PCI

BHUBANESWAR, India - Nov. 17, 2025 - PRLog -- Dr. Gyana Ranjan Nayak, Interventional Cardiologist at IMS & SUM Hospital, has successfully performed a highly complex cardiac procedure on a 68-year-old patient suffering from unstable angina, achieving success where a previous attempt at another facility had failed.

The patient, who had been experiencing poorly controlled chest pain despite medication, required a specialized intervention called Chronic Total Occlusion Percutaneous Coronary Intervention (CTO-PCI) to restore blood flow in a completely blocked heart artery. The procedure is considered one of the most challenging in interventional cardiology, with higher complication rates than standard cardiac interventions.

The Challenge

The case presented multiple obstacles that made it exceptionally difficult. The patient's Left Anterior Descending (LAD) artery — a critical vessel supplying blood to the heart — was completely blocked near a major branch point with what cardiologists call a "blunt stump," making wire navigation extremely challenging. Adding to the complexity, a previous attempt at another hospital had been unsuccessful.

"CTO-PCI requires specialized equipment including advanced guidewires, microcatheters, and sometimes intravascular ultrasound guidance," explained Dr. Nayak. "These are not routine cases, and success requires significant experience and technical skill, particularly when dealing with previously failed attempts."

The Solution

Dr. Nayak and his team employed an antegrade wire escalation technique, progressively using increasingly sophisticated guidewires — FIELDER XT-A, GAIA III, and ultimately achieving successful crossing with the MIRACLE 6 wire. Microcatheter support was maintained throughout the procedure to ensure precise navigation through the blocked artery.

The meticulous approach paid off. The completely blocked artery was successfully reopened, restoring normal blood flow (TIMI-3 flow) in the LAD. The patient's unstable angina stabilized immediately, symptoms improved significantly, and the final angiographic result demonstrated excellent restoration of cardiac blood supply.

Growing Expertise in Complex Cardiac Care

The successful outcome reflects the growing expertise at IMS & SUM Hospital in handling complex cardiac interventions. "We routinely perform complex PCI procedures, including both antegrade and retrograde CTO techniques," said Dr. Nayak. "This is possible thanks to our experienced team of cardiologists, dedicated cathlab staff, and enthusiastic residents who are committed to advancing cardiac care in Odisha."

The patient has since recovered well and continues to be monitored by the cardiology team at IMS & SUM Hospital.
