Summary
Echocardiography effectively assesses right ventricular (RV) function in severe mitral regurgitation (MR) patients. Preoperative RV function, measured by TAPSE and Sa, predicts postoperative outcomes after mitral valve replacement.
Area of Science:
- Cardiology
- Cardiac Surgery
- Echocardiography
Background:
- Severe mitral regurgitation (MR) can impact right ventricular (RV) function.
- Preoperative assessment of RV function is crucial for predicting outcomes in MR patients undergoing surgery.
Purpose of the Study:
- To evaluate right ventricular (RV) function in patients with severe mitral regurgitation (MR).
- To determine the relationship between preoperative and postoperative parameters in these patients.
Main Methods:
- Echocardiographic assessment of RV function using tricuspid annular plane systolic excursion (TAPSE) and peak systolic velocity of the lateral tricuspid annulus (Sa).
- Study included 45 patients with severe organic MR undergoing mitral valve replacement with posterior chordal sparing.
- Analysis of preoperative and postoperative echocardiographic and clinical parameters.
Main Results:
- A high prevalence of RV dysfunction was observed preoperatively (TAPSE < 22 mm in 66.6%, Sa < 11 cm/sec in 62.2%).
- Preoperative TAPSE and Sa were significantly correlated with each other and with various left ventricular parameters.
- Postoperative TAPSE and Sa showed significant decreases, and 46.6% of patients experienced a decrease in LVEF >10%.
- Multivariate analysis identified preoperative TAPSE and Sa as significant predictors of the study endpoint (decrease in LVEF >10%).
Conclusions:
- Echocardiographic assessment of RV function is a simple and valuable tool in patients with severe MR.
- Preoperative RV function parameters (TAPSE and Sa) provide important prognostic information for patients undergoing mitral valve surgery.

01:20Mitral Regurgitation I: Introduction
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...
01:23Mitral Regurgitation II: Clinical Features and Diagnostic Tests
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...
01:28Mitral Regurgitation IV: Nursing Management
Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...
01:25Mitral Regurgitation III: Medical Management
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...
01:22Mitral Stenosis I: Introduction
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...
01:22Mitral Valve Prolapse II: Assessment and Management
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 tachycardia.
