🫀 100 Echo Signs Every Cardiologist Should Know B-BUMP SIGN 📈 A classic M-mode clue to elevated LV filling pressure 🔍 WHAT IS THE B-BUMP? The B-bump is an abnormal late-diastolic configuration of the mitral valve seen on M-mode echocardiography. It appears as a small bump or plateau between the A and C points, with the mitral valve remaining partially open before closure. ⏱️ WHEN DOES IT OCCUR? ⚠️ The B-bump is a LATE-DIASTOLIC phenomenon. It occurs after the A point and before mitral valve closure (C point). 🔍 WHY DOES IT OCCUR? ⬆️ LV end-diastolic pressure ⬇️ Transmitral pressure gradient during late diastole ➡️ Mitral leaflets remain partially open ➡️ Abnormal late-diastolic leaflet motion ➡️ B-bump ❤️ CLINICAL ASSOCIATIONS The B-bump has been described in: 🔸 Elevated LVEDP 🔸 Reduced LV compliance 🔸 Severe LV systolic dysfunction 🔸 Ischemic cardiomyopathy 🔸 Dilated cardiomyopathy 💡 ECHO PEARL 📈 B-BUMP = LATE-DIASTOLIC MITRAL LEAFLET ABNORMALITY 120Sep 1

"Dagger-like Q waves" refer to narrow and deep Q waves that primarily occur in septal hypertrophy in hypertrophic cardiomyopathy. "Dagger" means a short sword, representing Q waves with a sharp, dagger-like shape. From the lateral wall leads, the septal excitation moves in a direction away from them, which is why Q waves often appear centered on the lateral wall leads. 103Sep 1 What Echo sign suggests elevated LV filling pressure? 🔍 B-Bump Sign 114Sep 1
