A 19-year-old female with a 2-day history of involuntary fast jerk-like movements of the left upper and lower extremities presented at the emergency department. Patient had no other known comorbidities and family history was unremarkable. Anti-streptolysin O titer (ASO) and C-reactive protein (CRP) were all normal. Two-dimensional echocardiography (2D Echo) revealed thickened anterior mitral valve leaflet with prolapsed A2 scallop, mild mitral regurgitation, thickened right coronary cusp of aortic valve without restriction of motion, trivial aortic regurgitation, other findings were unremarkable. Patient was managed as a case of Sydenham’s chorea secondary to acute rheumatic fever, with valvular heart disease secondary. Patient was initially started on valproic acid 500mg tablet every 8 hours, benzathine penicillin 1.2M units intramuscular, and carvedilol 12.5mg/tablet twice a day. The patient was then shifted to haloperidol 5mg ¼ tablet twice a day, diphenhydramine 50mg intravenously coinciding with haloperidol doses due to visual side effects of valproic acid. This report highlights the importance of a high index of suspicion and complete history and physical examination in order to diagnose and manage movement disorders in a low-income setting.

Suicide left ventricle describes the development of dynamic intraventricular gradients after aortic valve replacement due to acute hemodynamic changes that happen after relieving the obstruction leading to hemodynamic collapse. This is a rare complication in transcatheter aortic valve replacement and is underreported in surgical aortic valve replacement (SAVR). We present the case of a male patient who presented with suicide left ventricle after SAVR.

This is the case of a 62-year-old male with prior modified Bentall’s procedure using a 23-mm bioprosthetic valve last 2013 who came in with progressive heart failure symptoms. On physical examination, vital signs are stable. Physical exam revealed rhonchi on both lung fields and irregular rhythm with a grade 3 systolic ejection murmur at the aortic area. A 2-dimensional transthoracic echocardiogram showed an ejection fraction of 25%, aortic valve area of 1.0 cm2 and mean gradient of 21 mmHg consistent with severe low-flow, low-gradient aortic stenosis (AS). Options for re-do surgical aortic valve replacement (SAVR) were discussed. Since the patient was deemed high risk for another surgery, the option for transcatheter aortic valve in surgical aortic valve (TAV-in-SAV) was considered. The patient underwent successful TAV-in-SAV using a 26-mm self-expanding bioprosthetic valve. Post-procedure, there was significant improvement of functional capacity from class IV to class I.

Stent migration is one of the common complications following transcatheter valve implantation. This study aims to design a "drum-shaped" balloon-expandable aortic valve stent to address this issue and conduct a mechanical analysis. The implantation process of the stent was evaluated using a method that combines numerical simulation and in vitro experiments. Furthermore, the fatigue process of the stent under pulsatile cyclic loading was simulated, and its fatigue performance was assessed using a Goodman diagram. The process of the stent migrating toward the left ventricular side was simulated, and the force-displacement curve of the stent was extracted to evaluate its anti- migration performance. The results showed that all five stent models could be crimped into a 14F sheath and enabled uniform expansion of the native valve leaflets. The stress in each stent was below the ultimate stress, so no fatigue fracture occurred. As the cell height ratio decreased, the contact area fraction between the stent and the aortic root gradually decreased. However, the mean contact force and the maximum anti-migration force first decreased and then increased. Specifically, model S5 had the smallest contact area fraction but the largest mean contact force and maximum anti-migration force, reaching approximately 0.16 MPa and 10.73 N, respectively. The designed stent achieves a "drum-shaped" change after expansion and has good anti-migration performance.

OBJECTIVES: To analyze sex and age distribution of global disease burden of calcific aortic valve disease (CAVD) from 1990 to 2021. METHODS: CAVD data during 1990-2021 were obtained from the IHME website for Global Burden of Disease (GBD). The prevalence, mortality, years lived with disability (YLDs), and disability-adjusted life years (DALYs) were analyzed by gender and age groups. Joinpoint regression was used to calculate annual percentage change (APC) and average annual percentage change (AAPC). RESULTS: In 2021, there were 13.32 million CAVD patients and 142 000 deaths caused by CAVD globally. Age-standardized prevalence was higher in males (193.2/10⁵) than that in females (128.9/10⁵). Patients in 65-<85 age group accounted for 64.0% of total cases, while those ≥85 years old accounted for 16.1%. From 1990 to 2021, prevalence increased in both sexes with an AAPC of 0.72% for males and 0.57% for females, respectively. Prevalence grew fastest from 2000 to 2010, slowed thereafter, and declined from 2015 to 2021. In <65 years old, the mortality of males was 2.4 times higher than that of females, while in ≥85 years old, mortality of females (117.3/10⁵) exceeded that of males (99.1/10⁵). YLD rates increased with age, and were higher in males for all age groups. DALY rates decreased overall but increased in ≥85 years old, with a greater increase in females. CONCLUSIONS There are significant gender and age disparities in global disease burden of CAVD, with the elderly, especially super-elderly females deserving particular attention. It is recommended to develop personalized intervention strategies for these populations.

Transcatheter aortic valve replacement (TAVR) has emerged as the standard treatment for severe aortic stenosis, demonstrating comparable efficacy to traditional surgery in low and intermediate-risk patients. However, the bioprosthetic valves utilized in TAVR have a limited lifespan, and bioprosthetic valve failure, including calcification, rupture or infection may develop, leading to poor clinical outcomes. Elevated blood pressure has been identified as a key factor in aortic valve calcification, and its role in bioprosthetic valve failure is gaining increasing attention. Hypertension may accelerate the calcification process and exacerbate valve failure due to increased mechanical stress on the valve, activation of the renin-angiotensin system, and enhanced thrombus formation. Furthermore, elevated blood pressure interacts with prosthesis mismatch and paravalvular leak, jointly affecting valve durability. This review explores the impact of elevated blood pressure on bioprosthetic valve calcification and failure after TAVR, and emphasizes the importance of blood pressure control, optimized preoperative assessment, and appropriate valve selection in reducing valve failures.

OBJECTIVES: To analyze the early clinical outcomes of the Xcor^TM transcatheter aortic valve replacement (TAVR) system in treating severe aortic stenosis. This study has been registered at Chinese Clinical Trial Registry (ChiCTR2200065593). METHODS: This single-arm, prospective clinical trial enrolled patients with severe aortic stenosis treated with the Xcor^TM TAVR system at the Section of Heart Valve & Coronary Artery Surgery, Guangdong Provincial People's Hospital. Perioperative and follow-up parameters were compared to evaluate differences in hemodynamic outcomes. All-cause mortality, aortic regurgitation, paravalvular leakage, cerebrovascular events, and reoperation were analyzed. RESULTS: Thirty-two patients with severe aortic stenosis were included (20 males, 12 females), with (70.9±4.3) years old and a Society of Thoracic Surgeons (STS) score of 6.45% (6.07%, 7.28%). Notably, 87.5% of patients had New York Heart Association (NYHA) class≥Ⅲ. All patients underwent successful Xcor^TM bioprosthesis implantation, achieving an immediate technical success rate of 100.0% and device success rate of 96.9%. Mean aortic valve gradient decreased from (55.21±23.17) mmHg (1 mmHg=0.133 kPa) to (8.45±5.30) mmHg, peak aortic jet velocity decreased from (4.66±0.85) m/s to (1.99±0.48) m/s, aortic valve area increased from (0.66±0.21) cm² to (2.09±0.67) cm² (all P<0.01). Intraoperative ventricular fibrillation occurred in one patient, while one case exhibited moderate prosthetic valve regurgitation and paravalvular leakage post-procedure. At 12-month follow-up, sustained improvements were observed in cardiac function, left ventricular ejection fraction, hemodynamic parameters, and SF-12 quality-of-life scores (all P<0.01). All-cause mortality was 12.5% (4/32), with 13.8% (4/29) developing moderate paravalvular leakage. CONCLUSIONS The Xcor^TM TAVR system demonstrated favorable early outcomes in severe aortic stenosis patients, significantly improving symptoms and hemodynamics while exhibiting excellent performance in preventing malignant arrhythmias and coronary obstruction.

A case of an elderly patient with severe aortic insufficiency who carried high risks for surgical valve replacement. After a detailed preoperative evaluation, the patient successfully received transapical transcatheter aortic valve replacement. Postoperatively, complete left bundle branch block developed, resulting in impaired left ventricular function. Despite guideline-directed medical therapy for heart failure, cardiac function showed no significant recovery. At 4.5 months post-surgery, left bundle branch pacing was performed, leading to a marked improvement in cardiac function.

A 72-year-old patient with quadricuspid aortic valve underwent transcatheter aortic valve replacement due to severe valve stenosis accompanied by moderate insufficiency. As initially planned, the right coronary artery was protected during the procedure. However, after the artificial valve was released, the left coronary artery was found to be blocked, so a coronary protection stent was implanted in the left coronary artery ostium under the guidance of intravascular ultrasonography. This case indicates that for patients with a quadricuspid aortic valve undergoing transcatheter aortic valve replacement, in addition to preoperative measurement of the aortic root, attention should also be paid to the coronary artery obstruction caused by the displacement of the artificial valve frame during the procedure.

With the clinical generalization and popularization of transcatheter aortic valve replacement (TAVR), cerebrovascular events related to TAVR occur more frequently, which significantly impairs neurocognitive function, increases mortality, and seriously affects prognosis and quality of life in these patients. However, the reported incidence rates of TAVR-related stroke differ in literature due to inconsistent diagnostic criteria. According to the onset time, TAVR-related stroke can be divided into acute (≤24 h), subacute (24 h-30 d), early (31 d-1 year) and late (>1 year) types, and the cause of stroke generally varies according to the onset time. Both surgical (balloon aortic valvuloplasty, types of transcatheter heart valve, alternative access) and non-surgical (valvular calcium burden, bicuspid aortic valve, subclinical leaflet thrombosis, postoperative new-onset atrial fibrillation) can be related to the occurrence of TAVR-related stroke. Postprocedural monitoring, postprocedural antithrombotic therapy, and cerebral embolic protection devices are important for the prevention of TAVR-related stoke. This article reviews the research progress on TAVR-related stroke, focusing on its epidemiology, risk factors and preventive measures, aiming to provide reference for the clinical management of stroke in TAVR.
