概括
中心环状化 (MAC) 的严重程度不会影响跨导管大动脉置换 (TAVR) 后的存活率. 然而,A3段的MAC预测了心脏起器植入,而不是整体的MAC严重程度.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 心脏成像 - - 心脏成像
背景情况:
- 中心环状化 (MAC) 常见于接受过导管大动脉置换 (TAVR) 的患者.
- 对于MAC严重程度及其对TAVR结果的特定解剖分布的预后意义尚不清楚.
研究的目的:
- 调查MAC严重程度和解剖分布对TAVR后结果的影响.
- 具体来说,要确定MAC特征是否预测死亡率和需要心脏起器植入的需要.
主要方法:
- 642名接受TAVR (2016-2021) 的患者的回顾性分析.
- 排除之前有永久心脏起器植入的患者.
- 通过手术前CT扫描评估MAC严重程度和细分分布.
主要成果:
- 在15%的患者中存在严重的MAC;10.9%需要新的起器,24.6%在3年内死亡.
- 在MAC严重程度组之间,三年生存率没有显著差异.
- 在A3段的MAC局部化,而不是整体严重性,独立预测了心脏起器植入 (OR 5.10,p < 0.001).
结论:
- 马克的严重程度不能独立预测死亡率或心脏起器需要TAVR后.
- 在A3段内MAC的定位是导电干扰的重要独立预测因素,需要在TAVR后植入心脏起器.

Mitral Stenosis II: Clinical features and Diagnostic Tests
196
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral Stenosis I: Introduction
398
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Stenosis III: Medical Management
223
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Mitral Regurgitation III: Medical Management
257
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...

Mitral Valve Prolapse II: Assessment and Management
385
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Aortic Regurgitation III: Medical Management
375
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...
