Leaflet modification has rapidly evolved from niche innovation to a cornerstone of lifetime TAVR management.

In this discussion, Dr. Toby Rogers joins Dr. Andrei Pop to explore the latest data, device advances, and clinical decision-making behind Basilica, Shortcut, and emerging techniques like Telltale, Unicorn, and leaflet excision.

Key topics covered:

• History of leaflet modification — from LAMPOON to BASILICA and now device-guided procedures

• How Shortcut and Telltale are changing training and access

• Why leaflet modification is still primarily for TAV-in-SAV but expanding to redo-TAVR

• Balancing risk, complexity, and informed consent for lower-risk patients

• Role of CT simulation, FEops, and DASI modeling for lifetime valve planning

• When to err on the side of leaflet modification vs risking coronary obstruction

• Coronary height and valve-to-coronary distance — why those 2–4mm cutoffs aren’t gospel

• Future directions: routine modification, improved washout, and potential HALT reduction

• Access routes (carotid, transcaval, axillary) and practical tips for operators

• Comparing BASILICA, Shortcut, Unicorn, and Telltale—safety, mechanism, and learning curve

• Why new devices need structured trials before widespread use

This is essential viewing for structural heart operators refining TAVR-in-TAVR safety, coronary access strategies, and the future of leaflet modification.

LIMA interventions are rare, high-risk, and technically unforgiving. In this MurmurMD case session, Dr. Arvin Narula and Dr. Joe Walsh walk through an extremely challenging LIMA-to-LAD lesion involving heavy calcification, tortuosity, failed prior PCI, device entrapment, rotational atherectomy, Shockwave IVL, and management of unexpected graft thrombus.

This discussion delivers real-world strategy, troubleshooting, and device thinking you won’t find in textbooks.

Key insights from the case:

• Why left distal transradial can provide safer LIMA engagement

• The moment a Corsair microcatheter is “chewed up” — and why that signals severe calcium

• How to decide between more support, downsizing, or plaque modification

• When rotational atherectomy is safe in a LIMA graft — and when it’s not

• Why starting the burr in the native LAD, not the graft, may reduce risk

• How dual preparation (Rota + Shockwave) improves expansion

• DCB strategy for distal LAD disease

• Managing LIMA thrombus: ACT troubleshooting, lytics, aspiration, and stent “tattooing”

• Tricks for keeping thrombus from embolizing distally

• How to avoid dissecting the LIMA ostium during exchanges

• What to do if ACT remains subtherapeutic despite multiple boluses

This is an advanced case with invaluable pearls for anyone treating heavily calcified coronaries, bypass graft disease, or LIMA interventions.

Once considered niche, the Ross procedure is making a strong comeback. With improved techniques and long-term outcomes, it’s becoming a first-line option for younger patients with aortic valve disease.

In this episode, Dr. Chris Malaisrie (Northwestern Memorial, Chicago) joins Dr. Andrei Pop to discuss:

• Why the Ross procedure is resurging in high-volume centers

• Techniques to stabilize the autograft and prevent dilation (deep LVOT implant, Dacron grafts, wrapping with native root)

• Post-op strategies including strict blood pressure control for favorable remodeling

• Durability data: 85–90% freedom from reintervention at 10 years

• Managing failures: surgical re-repair, TAVR options, and future dedicated devices

• Patient selection: under 50, women, and those with small aortic roots

• The role of root enlargement and replacement in lifetime management
