The diagram illustrating a heart with tricuspid atresia and its transformation following a Fontan procedure offers a detailed comparison of congenital heart defect anatomy and surgical correction. This medical image serves as a vital educational tool for medical students, cardiologists, and healthcare professionals aiming to understand the structural challenges of tricuspid atresia and the surgical strategies employed to improve circulation. By examining the labeled parts, this guide provides a comprehensive exploration of the heart’s condition before and after the procedure, highlighting the clinical significance of this intervention.

Understanding your menstrual cycle is essential for reproductive health management, family planning, and overall wellness. Our new Menstrual Cycle Calculator helps you take control of your health by providing accurate predictions and valuable insights about your body.

Monitoring your baby’s growth is an essential part of ensuring their health and development. At Anatomy Note, we’re excited to introduce our Infant Percentile Calculator, a free online tool designed to help parents and caregivers assess their baby’s growth metrics accurately. Whether you're tracking height, weight, or head circumference, our calculator supports both WHO 2006 and CDC 2000 growth standards, making it a versatile choice for infants up to 36 months old.

The QTc interval is a critical measure in electrocardiography (EKG or ECG) that represents the time it takes for the heart's ventricles to contract and recover. The "c" in QTc stands for "corrected," as the QT interval is adjusted for heart rate to provide a standardized value. A prolonged or shortened QTc can indicate potential heart rhythm abnormalities, such as long QT syndrome or other cardiac conditions, which may lead to serious complications like arrhythmias.

Examine a detailed case of tonsillitis caused by strep throat, culture-positive, through this in-depth guide featuring a vivid image of the condition. This article is tailored for medical students and professionals, offering insights into the symptoms, causes, and treatments of tonsillitis and strep throat.

he illustration depicts a central venous catheter (CVC) secured to a patient's skin using suture fixation, one of the most traditional and widely practiced methods for preventing catheter displacement and migration.

The image displays a recently inserted temporary dual-lumen hemodialysis catheter positioned in the left internal jugular vein of a patient. This type of central venous access device serves as a crucial but temporary vascular access option for patients requiring urgent or short-term hemodialysis treatment. The catheter features two color-coded lumens—red for arterial (blood withdrawal) and blue for venous (blood return)—that facilitate the extracorporeal blood circuit necessary for dialysis.

Implanted venous access ports represent a significant advancement in long-term vascular access technology that combines reliable function with enhanced patient comfort and reduced infection risk. As illustrated in the image, these totally implantable devices consist of a reservoir (port) with a self-sealing septum connected to a catheter that extends through the venous system to terminate near the heart. Unlike external catheters, the entire system resides beneath the skin, requiring no external components when not in use.

Tunneled central venous catheters (CVCs) represent a specialized type of long-term vascular access device designed for patients requiring extended intravenous therapy. Unlike standard central lines, tunneled CVCs feature a subcutaneous tract between the venous entry site and the exit point on the skin, providing enhanced infection protection and improved stability. The image illustrates the anatomical positioning of a tunneled CVC, showing its path from the external exit site through a subcutaneous tunnel, into the right subclavian vein, and ultimately terminating in the superior vena cava near the right atrium.

The proper emptying of urinary drainage bags represents a critical component of comprehensive catheter care that significantly impacts infection prevention and overall patient safety. The image illustrates the correct technique for emptying a urinary collection bag, showing a healthcare provider wearing appropriate personal protective equipment (blue gloves) while draining urine from the bag into a calibrated container.
