A case of a 27-year-old female with prosthetic mitral valve is presented. Prolonged anticoagulation therapy was continued during pregnancy without complications. During puerperium, the dose of subcutaneous low molecular weight heparin was reduced due to subcutaneous blood effusions. Subsequently, the patient developed acute left ventricular heart failure due to prosthetic valve thrombosis. She underwent urgent surgery with new prosthetic valve implantation. Two weeks later she suffered another episode of acute mitral prosthetic valve thrombosis which was effectively treated with intravenous heparin. Difficulties concerning prolonged anticoagulation during pregnancy and puerperium in patients with prosthetic valves are discussed.

Mitral Valve Prolapse III: Nursing Management

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
Mitral Regurgitation I: Introduction01:20

Mitral 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...
Mitral Stenosis I: Introduction01:22

Mitral 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...

Mitral Stenosis III: Medical Management

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 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.
