Heart of the Data

Join us for an in-depth exploration of the VALIDATE-RFR clinical trial, which introduced a game-changing approach to coronary artery assessment that could transform interventional cardiology practice. We'll break down how the Resting Full-cycle Ratio (RFR) method overcomes the limitations of current diagnostic tools by analyzing pressure ratios throughout the entire cardiac cycle rather than j...

In this episode, we unpack the landmark DEFER 5-year trial , which asked a simple but game-changing question: should every coronary lesion be stented? The study showed that deferring PCI in lesions with an FFR > 0.75 was safe and effective, with excellent 5-year outcomes. We’ll explore how these results reshaped interventional cardiology and why the DEFER trial still guides decision-making toda...

In this episode, we explore the OCCUPI trial, a large randomized study comparing optical coherence tomography (OCT)-guided PCI to traditional angiography guidance in patients with complex coronary lesions. With over 1,600 patients enrolled, the trial showed that OCT guidance significantly reduced the rate of cardiac death, myocardial infarction, stent thrombosis, and target-vessel revascularizatio...

In this episode, we delve into the CALIPSO (Calcified Lesion Intervention Planning Steered by OCT) trial, a pivotal study evaluating the efficacy of optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) compared to traditional angiography-guided PCI in patients with moderate to severe calcified coronary lesions. Conducted across 12 centers in France, the trial demonstr...

In this episode, we delve into the RENOVATE-COMPLEX-PCI trial, a pivotal study evaluating the efficacy of intravascular imaging-guided percutaneous coronary intervention (PCI) compared to traditional angiography-guided PCI in patients with complex coronary artery disease. The trial demonstrated that using intravascular imaging techniques, such as intravascular ultrasound (IVUS) or optical coherenc...

In this episode, we explore the OCT-based calcium scoring system — a powerful tool for assessing coronary calcium severity prior to PCI. We break down how this algorithm evaluates calcium thickness, arc, and length to guide lesion preparation strategies, improve stent expansion, and ultimately enhance patient outcomes. Tune in for a practical discussion on how this imaging-based approach is reshap...

In this episode, we delve into the ILUMIEN IV trial, a significant study comparing optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) with traditional angiography-guided PCI in patients with complex coronary artery disease, including those with diabetes. While OCT guidance led to a larger minimum stent area and a notable reduction in stent thrombosis rates, it did n...

In this episode, we delve into the OCTIVUS trial, a landmark study comparing optical coherence tomography (OCT) and intravascular ultrasound (IVUS) guidance during percutaneous coronary intervention for complex coronary artery lesions. With over 2,000 patients enrolled across nine centers in South Korea, the trial assessed outcomes in challenging cases, including left main disease, bifurcations, a...

In this episode, we break down the OCTOBER trial — a pivotal study investigating whether optical coherence tomography (OCT)-guided PCI offers better outcomes than angiography alone in treating coronary bifurcation lesions. We explore the clinical rationale, study design, and what the findings mean for the evolving role of intravascular imaging in complex coronary interventions.

In this episode, we explore the groundbreaking FAME (Fractional Flow Reserve vs. Angiography for Multivessel Evaluation) trial, a pivotal study that reshaped how cardiologists approach multivessel coronary artery disease. Learn how measuring fractional flow reserve (FFR) changed the game in identifying which blockages truly need stenting — and which don't. We break down the study design, key f...
