Aortic annular calcification

UNLABELLED: Heyde's syndrome is described as angio-dysplastic gastrointestinal (GI) bleeding in elderly patients with degenerative severe calcific aortic stenosis (AS), resulting in anaemia. It was first reported by Edward C. Heyde in 1958 and thus carried his name. Although this condition is considered to develop in 10-20% of severe AS, it is a less familiar entity in clinical practice. With the rising geriatric population in the communities, there is a proportionate increase in the incidence of AS and accompanying Heyde's syndrome...

BACKGROUND: The assessment of left ventricular (LV) filling pressure (FP) is important for the management of aortic stenosis (AS) patients. Although, it is often restricted for predict LV FP in AS because of mitral annular calcification and a certain left ventricular hypertrophy. Thus, we tested the predictive ability of the algorithm for elevated LV FP in AS patients and also applied a recently-proposed echocardiographic scoring system of LV FP, visually assessed time difference between the mitral valve and tricuspid valve opening (VMT) score...

A distinctive complication with balloon-expandable (BE) THV platforms such as the Edwards Sapien (Edwards Lifescience) is the possibility of balloon rupture during THV deployment. Balloon rupture is a rare occurrence that can result in stroke due to fragment embolism, incomplete THV expansion, and/or vascular injury upon retrieval of the balloon. Careful evaluation of preoperative computed tomography is essential to identify high-risk cases. While annular and left ventricular outflow tract (LVOT) calcification are widely acknowledged as common risks for balloon injury, it's essential to note that balloon injury can manifest at various anatomical sites...

BACKGROUND/AIMS: Demonstrate through objective multidisciplinary imaging that subretinal drusenoid deposits (SDDs) in age-related macular degeneration (AMD) are linked to both coexistent valvular heart disease (VHD) and reduced systemic perfusion via cardiac index (CI). METHODS: Post-hoc analysis of cross-sectional study. 200 intermediate AMD (iAMD) subjects were assigned by masked readers to two groups: SDD (with or without drusen) and drusen (only) based on multimodal ophthalmic imaging...

BACKGROUND: Infranodal conduction disorders are common after transcatheter aortic valve replacement (TAVR). Risk factors are incompletely understood. OBJECTIVE: The purpose of this study was to assess the impact of valve implantation depth and calcium burden of the device landing zone on infranodal conduction intraprocedure pre- and post-TAVR. METHODS: In all patients undergoing TAVR between June 2020 and June 2021, the His-ventricle (HV) interval was measured pre- and post-valve deployment...

UNLABELLED: We report a 73-year-old female who underwent mitral valve replacement for degenerative mitral stenosis (DMS) and aortic valve replacement for aortic valve stenosis. She was transferred to our hospital because of congestive heart failure. Transthoracic echocardiogram demonstrated severe mitral valve stenosis and aortic valve stenosis. Transesophageal echocardiogram (TEE) revealed severe mitral annular calcification (MAC) and calcification of the anterior mitral leaflet without commissure fusion...

A 82-year-old woman came to our hospital because of orthopnea and cardiac cachexia. Echocardiography revealed a pressure gradient of 50 mmHg at the left ventricular outflow tract and that of 78 mmHg at the mid-ventricle. Systolic anterior motion of the mitral leaflet caused by mitral annular calcification and severe mitral regurgitation( MR) were observed. On the basis of the patient's age and poor general conditions, we resected abnormal myocardium on the septum from the outflow tract down to the apex via aortic valve and we left the mitral annular calcification...

BACKGROUND: Ventricular septal defect (VSD) is an unusual complication of transcatheter aortic valve implantation (TAVI). The risk factors are not well understood but may include oversizing, calcification amount and location, left-ventricular chamber morphology, and valve-in-valve (ViV) procedures. Percutaneous treatment is challenging but is usually the preferred option. CASE SUMMARY: An 80-year-old woman with two previous surgical aortic valve replacements was admitted to our Cardiology Department for decompensated heart failure...

BACKGROUND: ACURATE neo2 (Neo2) implantation is performed after systematic Balloon Aortic Valvuloplasty (BAV) in most patients. No reports exist about the feasibility and safety of direct Neo2 transcatheter aortic valve implantation (TAVI) in comparison to the standard practice. AIM: We aimed to identify the patients' baseline anatomical characteristics, procedural, and early post-procedural outcomes in patients treated using Neo2 with and without BAV. METHODOLOGY: This is a retrospective multicentre analysis of 499 patients with severe aortic stenosis who underwent TAVI using Neo2...

BACKGROUND: Transcatheter closure of transcatheter heart valve (THV)-related paravalvular leak (PVL) is associated with a high failure rate with available devices due to the complex interaction of THV and aortic/mitral annulus. OBJECTIVES: This study reports novel transcatheter techniques to treat PVL after THV. METHODS: We describe consecutive patients who underwent PVL closure after transcatheter aortic valve replacement (TAVR) or transcatheter mitral valve replacement (TMVR)...

BACKGROUND: Aortic valve calcium score is associated with hemodynamic severity of aortic stenosis. Whether this association is present in calcific mitral stenosis remains unknown. METHODS AND RESULTS: This study was a retrospective analysis of consecutive patients with mitral stenosis secondary to mitral annular calcification (MAC) undergoing transseptal catheterization. All patients underwent invasive mitral valve assessment via direct left atrial and left ventricular pressure measurement...

BACKGROUND: Failing bioprosthesis is an emerging issue due to (i) a shift towards liberal bioprosthesis implantation instead of mechanical prosthesis and (ii) an ageing population. Management of high-risk patients with bioprosthesis degeneration remains challenging. CASE SUMMARY: An 82-year-old patient with history of aortic and mitral valve replacement six years before presents with severe dyspnoea. Echocardiograpic assessment reveals (i) structural valve degeneration of the mitral prosthesis (severe stenosis and regurgitation) with concomitant major annular calcifications and (ii) structural valve degeneration of the aortic prosthesis with low-flow, low-gradient restenosis...

BACKGROUND: Cardiac valve calcification predisposes patients to a higher risk of adverse cardiovascular events. This study aimed to investigate the association between cardiac valve calcification and 1-year mortality in diabetic patients after lower-extremity amputation. METHODS: This was a retrospective study conducted on the clinical data of diabetic patients who underwent lower-extremity amputation admitted to the Sun Yat-sen Memorial Hospital, Guangzhou, Guangdong, China for diabetic foot ulcers needed lower extremity amputation surgery between July 2017 and March 2021...

BACKGROUND: Valve frame infolding (VFI) is a rare complication (1-3%) of transcatheter aortic valve implantation (TAVI), which primarily occurs in large sized self-expanding valves. We report the incidence of VFI in a small group of patients with highly calcified and extra-large aortic annuli, who underwent implantation of the newer generation 34mm Medtronic Evolut Pro+ (EP+) valve system. METHODS: A retrospective review was conducted on all patients presenting to a single centre experienced with TAVI in Sydney, NSW, Australia, between June and October 2022, for transfemoral TAVI using the Medtronic 34mm EP+ valve system...

Transcatheter mitral valve replacement (TMVR) is a novel and evolving field dedicated to addressing the therapeutic challenges posed by patients at high surgical risk with mitral valve disease. TMVR can be categorized into two distinct fields based on the type of device and its specific indications: TMVR with transcatheter aortic valves (TAV) and TMVR with dedicated devices. Similar to aortic stenosis, TMVR with TAV requires a rigid support structure to secure the valve in place. As a result, it is indicated for patients with failing bioprothesis or surgical rings or mitral valve disease associated with severe mitral annular calcification (MAC), which furnishes the necessary foundation for valve anchoring...

BACKGROUND: Appropriate management of mitral annular calcification associated with mitral valve surgery must be determined on a case-by-case basis. However, an established procedure remains uncertain. CASE PRESENTATION: This report describes a surgical case of severe mitral and aortic valve stenosis associated with severe mitral annular calcification in a 71-year-old woman who underwent mitral valve replacement with a collar-reinforced mitral prosthesis. The patient underwent surgical repair after the treatment for heart failure...

Mitral regurgitation (MR) associated with mitral annular calcification (MAC) is surgically challenging, and valve-in-MAC procedures using transcatheter aortic valve replacement (TAVR) devices have poor outcomes. Transcatheter mitral valve replacement (TMVR) may be an option. Concomitant TAVR and TMVR are limited to 2 reports. We describe the first case of concomitant TAVR and TMVR-in-MAC procedures. ( Level of Difficulty: Advanced. ).
