背景:
- 右心室 (RV) の不律症の患者の予後は,しばしば不確実である.
- RV不律症における突然死に関する予測要因については,さらなる解明が必要である.
研究 の 目的:
- 放射性核素血管図 (RNA) を用いて,RVおよび左心室 (LV) の関与の予後値を将来的に評価する.
- 重度のRV不律症の患者の突然死の予測要因を特定する.
主な方法:
- 重度のRV不律症の188人の患者の見通し評価.
- データ収集には,臨床プレゼンテーション,ECG,Holterモニタリング,プログラム刺激,RNAが含まれていました.
- 患者は,RNAの発見に基づいて分類された:正常なRV (グループI) またはLV異常があるか否か異常なRV (グループII).
主要な成果:
- フォローアップ期間は平均45ヶ月で,第2グループ (異常なRV/LV発見) のみで,突然死亡14例が報告されました.
- 臨床的および電気的データは死亡を予測できませんでした.
- 異常なRNAの発見 (P<0.005) とLVの異常 (P<0.01) は,突然の死の高度な予測力であった.
結論:
- アリズム変異性RV心筋症は,心臓死のリスクが高い重症疾患です.
- RVRNAの異常の証拠,特にLVの関与は,RV不律症患者の突然死の強い予測因子です.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Imaging Studies for Cardiovascular System III: X-Ray
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Imaging Studies for Cardiovascular System V: CT
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...
Cardiac Catheterization I: Pre-Procedure Overview
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
