CALIPSO Trial: OCT-Guided PCI in Calcified Coronary Lesions

RFR vs. iFR: Unmasking Hidden Coronary Blockages in the RCA with the Resting Full-Cycle Ratio

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 just during diastole, potentially catching significant blockages that traditional methods miss.

DEFER 5-Year Results: Redefining PCI Decisions

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 today.

OCCUPI Trial: OCT Guidance in Complex PCI

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 revascularization at one year. We discuss the trial design, key outcomes, and how these findings could shape the future of intravascular imaging in high-risk PCI cases.

CALIPSO Trial: OCT-Guided PCI in Calcified Coronary Lesions

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 demonstrated that OCT-guided PCI, utilizing a predefined lesion preparation algorithm, resulted in significantly larger minimal stent areas and improved stent expansion without increasing procedural risks. We explore the trial's design, key findings, and discuss the potential implications for interventional cardiology practice.

RENOVATE-COMPLEX-PCI: Enhancing Outcomes with Intravascular Imaging

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 coherence tomography (OCT), led to a significant reduction in target vessel failure rates. We explore the study's design, key findings, and discuss how these results are influencing current interventional cardiology practices.
