Insights

Understanding right-heart imaging is crucial for transcatheter tricuspid valve interventions. This study details optimal fluoroscopic angles for right-heart anatomy, integrating multislice computed tomography and echocardiography for improved procedural guidance.

Area of Science:

  • Cardiovascular Imaging
  • Interventional Cardiology
  • Cardiac Anatomy

Background:

  • Transcatheter tricuspid valve interventions demand precise right-heart imaging.
  • Integrating multimodality imaging is key for successful right-heart interventions.

Purpose of the Study:

  • To describe essential fluoroscopic viewing angles for right-heart chamber anatomy.
  • To correlate these angles with echocardiography using multislice computed tomography (MSCT).

Main Methods:

  • Utilized multislice computed tomography (MSCT) for pre-procedural planning.
  • Described specific fluoroscopic angles to visualize right-heart chambers.
  • Correlated MSCT-derived fluoroscopic angles with echocardiographic views.

Main Results:

  • Identified optimal fluoroscopic angles for appreciating right-heart chamber anatomy.
  • Demonstrated the relationship between MSCT-based fluoroscopic views and echocardiography.
  • Facilitated understanding of right-heart chamber visualization for interventions.

Conclusions:

  • MSCT is valuable for determining optimal fluoroscopic angles in transcatheter tricuspid interventions.
  • Integrating MSCT and echocardiography enhances right-heart chamber visualization.
  • Knowledge of these imaging relationships improves guidance for transcatheter right-heart procedures.

Anatomy of the Heart01:27

Anatomy of the Heart

The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Anatomy of the Heart01:20

Anatomy of the Heart

The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Heart Failure VII: Nursing Interventions

The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...

Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Nursing Interventions I: Taxonomy of Nursing Interventions

Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:
