@Ahmeddawas @jcspratt @Bhcintervention @Heartflow @ziadalinyc @crfheart In P4, we learned about when to use advanced calcium modification. Calcium density is a major component leading to stent underexpansion

This case is a #PCCT; the agreement with IVUS is almost perfect

[Carlos Collet MD PhD @ColletCarlos]

Back to work after #TCT! #CCTA planning in the #P5 RCT.

Severe eccentric and concentric calcification with negative remodeling at cross-section D—a challenging combination for stent expansion.

How would you treat?

PCR Perspectives: CT angiography beyond traditional risk factors

📺 & 🎧https://t.co/wEVSammLLW

@rajani_dr and @ColletCarlos discuss the role of coronary CT angiography in cardiovascular risk assessment among asymptomatic individuals. They review current approaches to risk stratification and examine whether imaging can provide incremental value beyond traditional clinical risk factors.

Also available as a podcast!

A milestone for CT-guided PCI!

The landmark P4 trial, presented at #TCT2026 and published in @NEJM, demonstrated noninferiority to IVUS-guided PCI at 12 months.

Proud of our @CCAD_MHIF @MHIF_Heart , the leading U.S. enrolling site. Grateful to everyone involved!

Congratulations to @ColletCarlos Collet and the P4 research team! @CoreAalst @crfheart

When I moved from full-time academic practice to industry, I had many of the same questions I now hear from colleagues.

Looking forward to joining @SCAI tomorrow to discuss opportunities beyond the cath lab and how to get started.

Join us!

Coronary CT #CCTA takes center stage at #TCT2026!

A mobile CT scanner right in the Expo Hall, where attendees are undergoing coronary CT scans with real-time analysis using @HeartFlow technology.

Bringing the future of CT-guided PCI directly to TCT!

P4 at #TCT2026: Can CT guide PCI?

1,100 patients, CCTA- vs IVUS-guided PCI:
• 1-year TVF: 4.1% vs 4.6%
• Non-inferiority achieved
• 17 min shorter procedural time
• 20 mL less contrast

@NishithChandra @CMichaelGibson @Hragy We mandated stent enhancement (stent Viz, boost, etc) in the CT to ensure adequate expansion

[C. Michael Gibson MD @CMichaelGibson]

Dr. Carlos Collet and Dr. C. Michael Gibson discuss the P4 Trial: Comprehensive CCTA-guided PCI strategy was associated with a lower rate of target vessel failure at 12 months compared to IVUS-guided PCI (4.1% vs. 4.8%) among patients with chronic coronary syndrome or stabilized acute coronary syndrome, supporting procedural safety and non-inferiority.

Presented at #TCT2026:

In a randomized trial, CCTA-guided PCI with structured preprocedural planning and intraprocedural guidance was noninferior to intravascular ultrasound–guided PCI with respect to target-vessel failure at 12 months. Full P4 trial results: https://t.co/oTj4ZoERlv

[Carlos Collet MD PhD @ColletCarlos]

Today, we unveil the P4 randomized trial

The main question:
Can CT-guided PCI achieve similar outcomes compared to IVUS-guided PCI?
