- 心脏病学 心脏病学
- 心声回声图 (Echocardiography) 是一种心声回声图.
- 心脏成像 - - 心脏成像
背景情况:
- 静脉收缩区域 (VCA) 的三维回声心脏图形平面测量是分级二次三回 (STR) 的有前途的方法.
- VCA避免了关于吐孔的几何假设,提供了更直接的评估.
- 目前对STR严重性的分级系统可以通过更准确的定量参数来改进.
研究的目的:
- 为五级STR严重性系统定义VCA值.
- 为了确定与不良临床结果相关的VCA截止值.
- 与传统的定量参数相比,评估VCA的增量预后值.

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...

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

01:15Aortic Regurgitation I: Introduction
456
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

385
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
