AI Article Synopsis
- A 54-year-old woman developed aortic regurgitation due to a ruptured fibrous strand in a fenestrated aortic valve cusp, which is uncommon.
- During a routine health check, a diastolic murmur was detected and echocardiography revealed severe regurgitation along with a mobile mass on the valve.
- After aortic valve replacement surgery, a ruptured strand and cusp laceration were found, and histopathology indicated myxomatous degeneration; she recovered well and was discharged 14 days post-surgery.
Article Abstract
Fenestration of the aortic valve cusps rarely causes aortic regurgitation. A 54-year-old woman was diagnosed with aortic regurgitation secondary to a ruptured fibrous strand in a fenestrated aortic valve cusp. Diastolic murmur was pointed out during health checkup five months earlier, and transthoracic echocardiography revealed severe aortic valve regurgitation with a mobile mass attached to the aortic valve cusp. The patient underwent aortic valve replacement. Intraoperatively, we observed a ruptured fibrous strand attached to the non-coronary cusp and cusp laceration, both of which caused severe aortic regurgitation. Histopathological examination of the resected specimen showed myxomatous degeneration. The patient's postoperative course was uneventful, and she was discharged in a stable condition on postoperative day 14.

A Novel Staging System of Cardiac Damage in Aortic Stenosis based on Multi-Chamber Myocardial Deformation.
Eur Heart J Cardiovasc Imaging
January 2025
Department of Cardiology, Istituto Auxologico Italiano, IRCCS, Milan, Italy.
Aims: This study evaluates whether multi-chamber myocardial deformation analysis using speckle tracking echocardiography (STE) can enhance validated current staging systems and improve risk stratification for patients with moderate-to-severe aortic stenosis (AS).
Methods And Results: We reanalyzed 2D, Doppler, and STE data obtained from two cohorts: derivation (654 patients, median age: 82 years; 51% men) and validation (237 patients, median age: 77 years; 55% men) with at least moderate AS (aortic valve area<1.5 cm2).
Ross procedure for aortic regurgitation versus stenosis in adults with and without autograft support.
Eur J Cardiothorac Surg
January 2025
Department of Cardiac Surgery, University Hospital Quironsalud Madrid, Spain.
Objectives: The Ross procedure for aortic regurgitation (AR) and abnormal aortic valve morphologies is associated with an increased risk of autograft dilatation. Autograft support may ameliorate this problem. We analyzed the results for all haemodynamic lesions and the effect of autograft support.

Eur Heart J Case Rep

The Second Department of Internal Medicine, University of Toyama, 2630 Sugitani, Toyama, Toyama 930-0194, Japan.
Background: Self-expanding valves used in transcatheter aortic valve implantation (TAVI) are designed to allow recapture and repositioning, facilitating optimal placement and mitigating conduction disturbances and paravalvular leakage. Here, we present a rare case in which the Navitor (Abbott Structural Heart, Santa Clara, CA, USA) could not be recaptured.
Case Summary: An 81-year-old Japanese woman with very severe aortic stenosis and a massively calcified nodule at the non-coronary cusp (NCC) underwent TAVI with a 25 mm Navitor valve.
Complicated infective endocarditis of the bioprosthetic mitral valve following the transcatheter mitral valve-in-valve procedure: a case report and literature review.
Eur Heart J Case Rep

Tehran Heart Center, Cardiovascular Diseases Research Institute, Tehran University of Medical Sciences, North Kargar Ave, Tehran 1411713138, Iran.
Background: Since the transcatheter valve-in-valve (ViV) procedure was introduced in 2007, a few cases of infective endocarditis (IE) following the ViV procedure have been reported, which can be predisposed by older age, pre-existing medical conditions, and procedural techniques. Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.
