🫀 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

Diagnosis: left upper lobe collapse. Sign: Luftsichel sign. In an elderly patient, the important next question is why the upper lobe has collapsed; an obstructing endobronchial lesion, including bronchogenic carcinoma, needs to be excluded, usually with CT and often bronchoscopy.

Lancisi’s Sign 🔹 Definition: A giant V-wave in the internal jugular venous pulse during ventricular systole. 🔹 Cause: Backflow of blood into the right atrium due to tricuspid valve incompetence. 🔹 Significance: A characteristic sign of severe tricuspid regurgitation (TR).

Pulmonary function tests (PFTs) in asthma show: • Decrease in FEVl of more than 20% with the use of methacholine or histamine • Increase in the diffusion capacity of the lung for carbon monoxide (DLCO) Virtue_USMLE

Nitrates are most commonly associated with postural (orthostatic) hypotension because they cause significant venodilation, reducing venous return (preload). This effect can be particularly pronounced when the patient suddenly stands. Alpha-blockers: also classically associated with postural hypotension, especially the first-dose effect ⬛ Beta-blockers: may contribute, but less commonly 🟪 ACE inhibitors: generally have a lower risk 🟩 Calcium channel blockers: can cause hypotension, but postural hypotension is less characteristic
