Cardiomyopathy VII: Pre and Post Operative Nursing Management

27
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Mitral Valve Prolapse II: Assessment and Management

39
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

39
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 I: Introduction

53
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Aortic Regurgitation I: Introduction

35
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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

51
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...

科学分野:

  • 小児心臓科
  • 生まれつき の 心臓 手術
  • エコーカルディオグラフィー

背景:

  • 完全な心房間隔膜欠陥 (cAVSD) の修復結果は改善したが,左心房間隔膜 (LAVV) の再手術は依然として懸念される.
  • LAVVの再手術の必要性を予測することは,cAVSDの修復における外科的意思決定を最適化するために極めて重要です.

研究 の 目的:

  • cAVSDの修復後のLAVV再手術のイントラオペラティブエコーカルディオグラフィの予測要因を特定する.
  • LAVV 吐 (LAVVR) の重症度に対する第2回バイパスの影響を評価する.

主な方法:

  • cAVSDの修復を受けた134人の患者の遡及レビュー (2010年~2020年).
  • LAVVRを評価するために,手術中のバイパス後のエコーカルジオグラムの個別レビュー.
  • 医療記録から収集された長期追跡データ

主要な成果:

  • 患者の20. 1%は,第1回バイパス後に中等またはより高いLAVVRを示した.
  • 2回目のバイパス手術は,平均LAVVRグレード (2. 2から1. 3),p=0. 004) を改善し,患者の8. 2%で行われました.
  • 10年後のLAVV再操作は,中程度のLAVVR (61. 2%) と特異的なジェット (65. 4%) に比べて,軽度のLAVVR (89. 6%) と中央ジェット (92. 7%) よりも著しく低かった.

結論:

  • 中度またはより高いLAVVRおよび外心的なLAVVRジェットは,手術中のエコーカルジオグラムで,再手術の有意な予測指標です.
  • LAVVの再修復のための2回目のバイパス走行は,LAVVRの重症性を改善するのに有効です.
  • cAVSD手術中のLAVV再修復に関する外科的決定を導くことができる.
