Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

4
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...

Aneurysm III: Interprofessional Care

2
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Mitral Valve Prolapse II: Assessment and Management

3
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...

Mitral Valve Prolapse III: Nursing Management

5
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 Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

2
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...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

3
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...

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology

Background:

  • Transcatheter aortic valve implantation (TAVI) is a minimally invasive treatment for severe aortic stenosis.
  • While generally safe, TAVI carries a risk of rare complications, including prosthetic leaflet dislodgment.

Observation:

  • A case of acute free aortic regurgitation following TAVI is presented.
  • The complication resulted from prosthetic leaflet dislodgment after valve post-dilatation.
  • Transoesophageal echocardiography confirmed prosthetic leaflet dysfunction.

Findings:

  • Heavily calcified native aortic valve leaflets likely contributed to paravalvular regurgitation.
  • Post-dilatation, while optimizing valve function, can precipitate leaflet dislodgment.
  • Intravascular lithotripsy may be a future consideration to manage calcified valves and reduce regurgitation risk.

Implications:

  • Acute prosthetic leaflet dislodgment is a rare but life-threatening TAVI complication.
  • Early diagnosis and immediate management are critical for patient survival and outcomes.
  • This case highlights the importance of careful valve deployment and post-procedural assessment.
