Summary
Left atrial dissection is a rare complication after redo cardiac surgery. Advanced imaging like echocardiography and CT scans are crucial for diagnosis and guiding treatment decisions.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Left atrial dissection is a rare but potentially fatal complication following cardiac surgery.
- Early diagnosis and appropriate management are critical for patient outcomes.
Observation:
- A 66-year-old female developed left atrial dissection post-redo mitral and aortic valve replacement for degenerative disease and endocarditis.
- The mitral valve was implanted in a supra-annular position due to annular destruction.
- Postoperative refractory acute heart failure was attributed to the left atrial wall dissection.
Findings:
- Transesophageal echocardiography and cardiac CT scans confirmed the left atrial wall dissection.
- Surgical intervention was considered high-risk due to the patient's condition and prior surgeries.
- A multidisciplinary team decided on palliative care support due to the high surgical risk.
Implications:
- Left atrial dissection can occur even after redo cardiac procedures, particularly with supra-annular valve implantation.
- Multimodal imaging is essential for accurate diagnosis of this rare complication.
- Careful consideration of surgical risks versus palliative care is necessary in complex cases.

25
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, 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...

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

01:20Mitral Regurgitation I: Introduction
28
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...

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

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...
