How the ECG Tells You Where VT Is Coming From

1️⃣ When a rhythm comes from the ventricles, it travels slowly across muscle instead of racing through the Purkinje system. That’s why VT is wide, fast, and regular.

“Teardrop Heart” in Congenital Absence of Pericardium

🫀 Why the “teardrop” shape?

• No pericardial restraint → heart is unusually mobile in the chest
• Leftward displacement → heart shifts toward the left hemithorax
• RV can appear abnormally prominent and findings may mimic those of ASD

✨ Result:
• The LV elongates and stretches downward
• Cardiac silhouette appears narrow superiorly + bulbous inferiorly

🫀 #CardioNugget:

Coaptation Length vs Coaptation Depth

📍 Coaptation Length
➡️ Length of leaflet overlap during systole
➡️ Think: “How much do the leaflets seal?”
🔴 Short length = poor closure → ↑ MR
✅ Favorable for MitraClip: ≥2 mm

📍 Coaptation Depth (aka tenting depth)

➡️ Distance from annular plane → coaptation point
➡️ Think: “How far are the leaflets pulled down?”
🔴 Increased depth = leaflet tethering → functional MR
⚠️ >10 mm → worse repair outcomes

[Ritika Tuli @RitikaTuliMD]

🫀 #CardioNugget: Flail Gap vs Flail Width in MR

📍 Flail Gap
➡️ Distance between the flail leaflet tip and the coaptation line
➡️ Think: “How far is the leaflet flying into the LA?”
🔴 Larger gap = more severe MR
✅ MitraClip-friendly: <10 mm

📍 Flail Width
➡️ Medial–lateral extent of the flail segment
➡️ Think: “How wide is the damaged portion?”
🔴 Wider segment = more complex repair
✅ MitraClip-friendly: <15 mm

🎯 Why it matters?
Both help determine severity + feasibility of transcatheter repair (e.g., MitraClip)

📍n=3000 NVAF
📍WATCHMAN FLX LAAC vs NOAC
✅LAAC met NI for 3y CV ☠️, stroke, or systemic emb
✅🩸 lower w LAAC
⚠️Important caveat: the NI margin was 4.8%, as large as the overall event rate.
Large NI margin only non-proc bleeds included

Presented at #ACC26:

Among patients with a preserved ejection fraction at least 1 year after myocardial infarction, stopping beta-blockers was noninferior to continuing therapy with respect to major clinical outcomes. Full SMART-DECISION trial results: https://t.co/dZS03RaTcA

Great presentation on prevention medications. One thing I noticed- a lot of us still hesitant to prescribe GLP-1’s to our patients when indicated. Was great to have some more insights on GLP1 in cardiology practice. @ACCinTouch #ACC26 #GLP1

Digoxin in Rheumatic Heart Disease (DIG-RHD)

RCT evaluating digoxin in patients with HF with rheumatic heart disease
❤️ A long-standing therapy now undergoing rigorous evaluation in a contemporary population needed

Key results
💊4% relative risk ⤵️ of primary endpoint driven in those tx with digoxin by ⤵️ worsening HF
💊 Hospitalization for HF was very infrequent (2.8 vs. a mortality rate of 4.9 per 100 patient-years)
💊 1st trial evidence for digoxin as a safe treatment for reducing HF worsening in RHD

#SPIRIT-HF #ACC26
🧑‍⚕️ HF with preserved or mildly reduced EF (HFpEF/HFmrEF)—a large, underserved group with limited therapies
🧠 Does Spironolactone reduce CV death and HF hospitalizations, building on signals from prior trials like TOPCAT
📊 Trial was underpowered (COVID impact, lower enrollment, high drug discontinuation) → unable to definitively test hypothesis
⚠️ No clear primary outcome benefit; side effects and drug withdrawal were common, potentially blunting efficacy
💡 Takeaway:
Signal for benefit may still exist—but tolerability + adherence remain the real barriers in HFpEF therapy

Great Discussion by @dranulala 👏👏
