AI Article Synopsis

  • Anatomic connection between the mitral valve and aortic root can lead to functional changes in the mitral valve when there's a problem with the aorta, even if the mitral valve itself isn't directly involved.
  • A 34-year-old man with aortic valve endocarditis experienced severe aortic regurgitation and displacement of the mitral valve, resulting in moderate regurgitation.
  • After his aortic valve was replaced and the aorta was reconstructed, the mitral valve's structure and function improved without needing any direct intervention on the mitral valve itself.

Article Abstract

Anatomic continuity between the anterior mitral leaflet and the aortic root may predispose those patients with aortic root pathology to functional changes of the mitral valve without any involvement of this valve. A 34-year-old man presented with aortic valve endocarditis. Transthoracic echocardiograpy showed severe aortic regurgitation with a large aortic root abscess. The anterior leaflet of the mitral valve was displaced towards the apex of the heart causing moderate mitral regurgitation. The patient underwent aortic valve replacement with reconstruction of the aortic annulus and ventriculoaortic continuity. This procedure alone restored the mitral valve structure and function without any need for intervention on the mitral valve. Aortic abscess is a serious complication of aortic valve endocarditis and may alter the function of other structures of the heart, especially the mitral valve. Restoration of aortic wall integrity and left ventricular-aortic continuity usually restores the mitral valve structure and function if the valve is unaffected by the infection. A decision on the mitral valve should be made following correction of the aortic pathology.

Venoarterial extracorporeal membrane oxygenation weaning strategies are not standardized. When dealing with patients with complex physiologies and borderline haemodynamics, it is prudent to have a fail-safe method of approaching decannulation from extracorporeal membrane oxygenation. Standardizing the extracorporeal membrane oxygenation weaning strategy with a pump-controlled retrograde trial off protocol seems a feasible alternative to traditional venoarterial extracorporeal membrane oxygenation weaning approaches.

Background: Unlike non-rheumatic atrial fibrillation (AF), where left atrial thrombus (LAT) is predominantly confined to the left atrial appendage (LAA), a significant proportion of LAT in rheumatic AF occurs within the left atrial cavity (LAC). However, LAC thrombosis in rheumatic AF has not been extensively studied. This study aimed to evaluate the prevalence of LAT and its subtypes and identify potential predictors of LAT.

Mitral annular calcifications have been known to increase complexity during mitral valve replacement (MVR). Standard procedure requires decalcification followed by reconstruction of the mitral annulus prior to placing the prosthesis. While this is the ideal technique, it is not feasible in every patient due to the associated risks.
