Insights

Left ventricular false tendons (LVFTs) may be linked to heart structure and function changes, not just benign variants. Specific locations, like basal and middle LVFTs, are associated with reduced systolic function and dilation.

Area of Science:

  • Cardiology
  • Echocardiography
  • Cardiac Structure and Function

Background:

  • Left ventricular false tendons (LVFTs) are common intracardiac structures.
  • Traditionally considered benign, LVFTs have been anecdotally linked to arrhythmias and ventricular remodeling.
  • The association between LVFTs and left ventricular (LV) structural and functional changes requires further investigation.

Purpose of the Study:

  • To investigate the association between LVFTs and LV structural and functional changes using echocardiography.
  • To compare echocardiographic parameters in patients with and without LVFTs.

Main Methods:

  • Retrospective analysis of echocardiographic and clinical data from 126 patients with LVFTs and 85 age-matched controls.
  • Comparison of demographic, clinical, and echocardiographic parameters between the two groups.
  • Statistical analysis to identify associations between LVFTs and LV abnormalities, adjusting for covariates.

Main Results:

  • Patients with LVFTs exhibited higher prevalence of heart failure, LV dilation, moderate-to-severe mitral regurgitation, and diastolic dysfunction compared to controls.
  • LVFTs were associated with a significant reduction in LV systolic function.
  • Basal and middle LVFT locations were independently associated with reduced LV systolic function and LV dilation, respectively.

Conclusions:

  • LVFTs may not be benign findings and are associated with significant LV structural and functional abnormalities.
  • Basal and middle LVFTs appear to have more detrimental effects on LV function and structure.
  • Further prospective research is warranted to elucidate the pathophysiological role of LVFTs in LV dysfunction.

Heart Failure II: Pathophysiology

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...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

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...

Mitral Stenosis I: Introduction

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...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
