Insights

Patients who recovered from Coronavirus disease-2019 (COVID-19) showed impaired left atrial (LA) function. Echocardiography revealed significant differences in LA volumes and emptying fractions, indicating potential long-term cardiovascular risks.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Medical Imaging

Background:

  • Left atrial (LA) dysfunction is a significant risk factor for cardiovascular events.
  • Coronavirus disease-2019 (COVID-19) is a global pandemic with known cardiovascular implications.
  • The long-term effects of COVID-19 on cardiac function, particularly LA function, require further investigation.

Purpose of the Study:

  • To evaluate left atrial (LA) functions in patients who have recovered from COVID-19.
  • To compare LA function parameters between COVID-19 survivors and a healthy control group.

Main Methods:

  • A cohort of 60 COVID-19 recovered patients and 60 healthy controls were enrolled.
  • Echocardiography measurements were performed to assess cardiac function.
  • Demographic and echocardiographic characteristics were compared between the two groups.

Main Results:

  • COVID-19 survivors exhibited higher LA maximum volume (LAVmax) and LA pre-A volume, alongside a higher LA active emptying fraction.
  • A lower LA passive emptying fraction and decreased left ventricular ejection fraction were observed in the COVID-19 group.
  • Isovolumetric relaxation time was also reduced in patients recovered from COVID-19.

Conclusions:

  • Left atrial (LA) functions may be impaired in individuals following recovery from COVID-19 infection.
  • These findings suggest potential persistent cardiovascular sequelae after COVID-19.
  • Further research is warranted to understand the clinical significance and management of post-COVID-19 LA dysfunction.

Mitral Stenosis I: Introduction01:22

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

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...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
