Fetal Circulation01:14

Fetal Circulation

1.4K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

27
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Dysrhythmias I: Introduction01:15

Dysrhythmias I: Introduction

172
Dysrhythmias refers to abnormalities in the heart's rhythm. They result from disruptions in the heart's electrical conduction system, which includes the sinoatrial(SA)node, atrioventricular(AV) node, the bundle of His, bundle branches, and Purkinje fibers.Definition and PathophysiologyDysrhythmias result from disorders of impulse formation, impulse conduction, or both. The heart contains specialized cells in the sinoatrial node, atrioventricular node, and the bundle of His and Purkinje fibers...

Cardiopulmonary Resuscitation I: Adult

99
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

1.5K
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

1.6K
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...

Area of Science:

  • Cardiology
  • Maternal-Fetal Medicine
  • Electrophysiology

Background:

  • Complete atrioventricular block (CAVB) during pregnancy presents significant maternal and fetal risks.
  • Management necessitates a multidisciplinary strategy for optimal safety.

Observation:

  • A 27-year-old pregnant patient at 28 weeks gestation experienced syncopal episodes due to CAVB.
  • A permanent pacemaker was successfully implanted under local anesthesia, with the patient remaining stable.

Findings:

  • Pacemaker implantation in pregnant patients with symptomatic CAVB is a safe and effective intervention.
  • The procedure facilitated a healthy trans-vaginal delivery at term.

Implications:

  • Early diagnosis and intervention, including pacemaker implantation, are crucial for managing symptomatic CAVB in pregnancy.
  • A collaborative approach involving cardiologists and obstetricians improves maternal and fetal outcomes.
