In Conversation with: Dr. Kiran Reddy
Dr. Kiran Reddy’s career has crossed oceans and shifted from cardiology to a specialty that addresses nearly every organ system. After training in the United Kingdom and Ireland, Dr. Reddy moved to Edmonton, Alberta, attracted by robust opportunities in interventional radiology.
Interventional radiology uses imaging—fluoroscopy, CT, and ultrasound—to guide procedures through small incisions. These minimally invasive techniques reduce trauma and speed recovery.
Dr. Reddy notes the specialty’s broad reach; while others focus on single organs, interventional radiologists treat conditions across the lungs, blood vessels, and tumors from the neck down.

The Challenge of the Intermediate Patient
A primary focus of Dr. Reddy’s recent clinical work involves the management of pulmonary embolisms, which occur when blood clots, usually originating in the legs, travel through the heart and lodge in the pulmonary arteries.
Historically, medical professionals categorized these patients into two extremes: those with low- risk clots who could be managed with simple blood thinners, and those in a state of collapse who require aggressive, systemic “clot-busting” drugs.
The latter treatment, while effective at dissolving the primary obstruction, carries a significant risk of causing substantial bleeding in other parts of the body, including the brain.
Dr. Reddy’s research targets an intermediate group of patients who are not yet in critical failure but are too unstable for blood thinners alone. For these individuals, the emergence of mechanical thrombectomy has fundamentally changed the standard of care.
Mechanical Innovation in Clot Removal
The technology used to treat these intermediate cases involves inserting a catheter through a small incision in the leg and navigating it directly into the lungs. Current medical devices in the Canadian market have evolved to prioritize safety and efficiency.
Some systems use manual high-pressure suction to extract large, solid clots, while others utilize automated pumps equipped with algorithms that can distinguish between physical obstruction and free-flowing blood.
By physically removing the blockage rather than waiting for the body to dissolve it over weeks or months, physicians can provide immediate relief to the heart and lungs; this intervention is particularly crucial for preventing long-term complications such as chronic thromboembolic pulmonary hypertension, a condition where internal scarring from old clots leads to permanent, debilitating lung disease.
Systemic Benefits and the Future of Imaging
The adoption of these high-tech interventions also provides a significant benefit to the broader healthcare infrastructure. While the specialized equipment carries a high initial price tag, the ability to move a patient from the intensive care unit to a general ward in a matter of hours represents a massive cost saving.
Dr. Reddy emphasizes that reducing ICU stays not only saves thousands of dollars per night but also ensures that critical beds remain available for other emergency patients.
Looking ahead, the demand for these image-guided procedures is expected to increase as technology continues to replace more invasive surgical methods. Dr. Reddy remains an advocate for the growth of the field, noting that imaging has become the backbone of modern hospital care.
As the healthcare system moves toward more efficient, targeted treatments, the role of the interventional radiologist will continue to expand, offering patients safer outcomes through the precision of modern technology.
