Summary
Endoscopic surgery for severe mitral annular calcification (MAC) is safe and effective. Techniques like ultrasonic decalcification and balloon-expandable valve implantation enable successful outcomes with no operative deaths.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Techniques
- Valvular Heart Disease
Background:
- Mitral annular calcification (MAC) poses surgical challenges.
- Data on endoscopic approaches for severe MAC are limited.
- Understanding MAC is crucial for surgical planning.
Purpose of the Study:
- To summarize surgical understanding of MAC.
- To evaluate the application of endoscopic surgery for severe MAC.
- To report institutional experience with endoscopic mitral valve surgery in MAC patients.
Main Methods:
- Retrospective study of 25 patients with severe MAC undergoing endoscopic mitral surgery.
- Data collected from December 2020 to August 2024.
- Analysis included patient demographics, valve pathology, surgical techniques, and outcomes.
Main Results:
- 25 patients (average age 69.13 years) underwent endoscopic surgery.
- 48% had regurgitation, 48% stenosis; 16% had circumferential MAC.
- Mitral valve replacement (72%) or repair (28%) performed with no operative mortality, stroke, or AV complications.
Conclusions:
- Endoscopic surgery for severe MAC is feasible and safe.
- Successful outcomes achieved using ultrasonic decalcification, mechanical debridement, annular patching, and valve implantation.
- This approach offers a viable option for managing severe MAC.

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 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...

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...

39
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...

53
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

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...
