|November 21, 2017
Summary
256-slice computed tomography (CT) accurately visualizes pulmonary vein (PV) anatomy, providing crucial data for electrophysiologists performing radiofrequency catheter ablation (RFCA) therapy safely and efficiently.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Pulmonary vein (PV) anatomy is critical for successful radiofrequency catheter ablation (RFCA).
- Understanding anatomical variations is essential for procedural planning and patient safety.
Purpose of the Study:
- To evaluate pulmonary vein (PV) anatomy using 256-slice computed tomography (CT).
- To provide essential anatomical data for electrophysiologists before RFCA.
Main Methods:
- 102 patients with atrial fibrillation underwent 256-slice cardiac CT angiography.
- Three-dimensional volume-rendering and multiplanar-reformatting technologies were used to assess PV morphology, ostial diameter, orientation, and branching patterns.
Main Results:
- 72.5% of patients had four conventional PVs; variations included accessory and common PVs in 27.5% of patients.
- Significant variations in ostial size, shape, orientation, and branching patterns were observed.
- Right superior PVs were larger and more circular than left PVs; early branching was common in the right inferior PV.
Conclusions:
- 256-slice CT effectively visualizes complex PV anatomy.
- The detailed anatomical data obtained aids electrophysiologists in planning and executing RFCA procedures safely and efficiently.

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
