Extreme Angiographic-Physiologic Mismatch With Elevated Left Ventricular End-Diastolic Pressure
Summary
Translesional coronary pressure assesses coronary artery disease significance. Elevated left ventricular end diastolic pressure (LVEDP) may explain extreme visual-physiologic mismatch in patients.
Area of Science:
- Cardiology
- Interventional Cardiology
- Physiology
Background:
- Epicardial coronary artery disease (CAD) requires accurate hemodynamic assessment.
- Translesional pressure measurements are crucial for evaluating CAD significance.
- Angiographic-physiologic mismatch is a known challenge in CAD assessment.
Observation:
- A patient presented with a significant discrepancy between visual assessment of coronary arteries and physiological measurements.
- This visual-physiologic mismatch was notably extreme in the observed case.
- Markedly elevated left ventricular end diastolic pressure (LVEDP) was recorded in this patient.
Findings:
- The study highlights a potential new mechanism contributing to angiographic-physiologic mismatch.
- Elevated LVEDP may play a role in the discrepancy between imaging and pressure-derived significance of CAD.
- This finding challenges the sole attribution of mismatch to imaging limitations.
Implications:
- Revising the understanding of factors causing visual-physiologic mismatch in coronary artery disease.
- Considering LVEDP as a potential confounder in the interpretation of translesional pressure measurements.
- Improving the accuracy of hemodynamic assessment in patients with complex coronary artery disease.

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

72
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

64
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

01:20Mitral Regurgitation I: Introduction
76
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
