OCT-guided PCI improves survival after life-threatening heart attacks

Images coronary calcium imaging by optical coherence tomography (OCT) and high-definition intravascular ultrasound (IVUS).

Images of coronary calcium imaging by optical coherence tomography (OCT) and high-definition intravascular ultrasound (IVUS). A) OCT shows superficial calcium extending to the medial layer. The calcium, where thickness can be measured due to the optical properties of light penetration through the calcium crystal. B) Co-registered image on high-definition IVUS does not allow measurement of calcium thickness. C) OCT shows superficial calcium extending to the medial layer, where thickness cannot be measured due to the limited penetration depth of light. D) Co-registered image on high-definition IVUS does not allow measurement of calcium thickness. Images and caption courtesy of EuroIntervention and Ziad A.

Researchers explored data from nearly 4,000 STEMI patients, noting that optical coherence tomography may be a valuable first step of any treatment strategy. 

Managing stable angina: How cardiologists can find the right mix of revascularization, therapy and interventions

cardiologists evaluating the human heart to provide a treatment strategy

The management of stable angina has been evolving at a rapid rate. Using a one-size-fits-all strategy is becoming a thing of the past, replaced by a patient-centered approach that requires open communication and a healthy understanding of recent clinical research.

Intravascular lithotripsy, the technology at heart of $13B acquisition, linked to positive real-world data

The Shockwave Medical M5+ new peripheral intravascular lithotripsy (IVL) catheter cuts procedures times in half and was showed for the first time at the American College of Cardiology (ACC) 2022 meeting. It is designed to break up calcium in heavily calcified arteries to avoid the need for vessel trauma caused by high pressure angioplasty.

The calcified plaque-shattering technology developed by Shockwave Medical continues to gain momentum. As more care teams start using IVL during PCI, researchers are paying close attention to its long-term impact on patient care.
