Late-phase left ventricular pseudoaneurysm after three-time mitral valve surgery.
Journal of Surgical Case Reports
|January 24, 2022
Summary
Late rupture of the left ventricle posterior wall after mitral valve replacement (MVR) can cause left ventricular pseudoaneurysms (LVPAs). This case report details a successful surgical technique for repairing a LVPA during MVR in a patient with a history of endocarditis.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Adult Congenital Heart Disease
Background:
- Rupture of the left ventricular posterior wall is a rare but fatal complication of mitral valve replacement (MVR).
- Late-phase rupture, occurring years after MVR, can manifest as left ventricular pseudoaneurysms (LVPAs).
- Surgical repair of LVPAs, especially in patients with prior cardiac surgeries, presents significant challenges.
Observation:
- A 40-year-old male with a history of three mitral valve surgeries for infectious endocarditis was incidentally diagnosed with a symptomatic left ventricular aneurysm.
- The patient underwent successful closure of the left ventricular pseudoaneurysm concurrently with mitral valve replacement.
Findings:
- This case highlights the successful surgical management of a late-onset left ventricular pseudoaneurysm in a patient with a complex cardiac history.
- The report describes a specific surgical technique employed for the closure of the LVPA during MVR.
Implications:
- This successful repair demonstrates a viable approach for managing challenging LVPA cases during MVR.
- The findings may contribute to improved surgical strategies for late complications following mitral valve surgery.
- Further research into optimal techniques for LVPA repair in complex cases is warranted.

01:22Mitral Stenosis I: Introduction
72
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...

01:27Mitral Valve Prolapse I: Introduction
62
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...

01:20Mitral Regurgitation I: Introduction
76
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...

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 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, 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.
