Philippine Journal of Internal Medicine 2026;64(1):105-109
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.

A 91-year-old male patient was admitted with a history of mitral valve prolapse diagnosed by physical examination ten years prior and recent onset of exertional chest discomfort persisting for over one month. Transthoracic echocardiography showed that the anterior leaflet of mitral valve was thickened and prolapsed with severe regurgitation, and transesophageal echocardiography further confirmed that the anterior and posterior leaflets of mitral valve were prolapsed with massive regurgitation (A1, A2, A3, P1 and P2 were all prolapsed). Thus, the diagnosis of Barlow syndrome was considered. Transcatheter edge-to-edge mitral repair was performed with two MitraClipTM G4 XTWs. After a 10 months follow-up, the patient's cardiac function was significantly improved, and the degree of mitral regurgitation was mild.

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 evaluate the short-term clinical efficacy of transcatheter edge-to-edge repair (TEER) in patients with moderate to severe mitral regurgitation.
METHODS:
Clinical data of patients with moderate to severe mitral regurgitation who underwent TEER in the Department of Cardiology, the First Affiliated Hospital of Xi'an Jiaotong University from April 2021 to May 2024, were retrospectively analyzed, including preoperative baseline clinical and echocardiography data, intraoperative data and 6-month postoperative follow-up data.
RESULTS:
A total of 67 patients' (47 males and 20 females) data were included, of whom 62 completed 6-month follow-up. The immediately postoperative success rate was 88.1% (59/67), and 83.9% (52/62) patients exhibited mitral regurgitation ≤2+ at 6 months postoperatively, showing significant improvement compared with preoperative (P<0.05). The proportion of patients with mitral regurgitation ≤2+ at 6 months was significantly higher in the degenerative mitral regurgitation (DMR) group than that in the functional mitral regurgitation (FMR) group (P<0.05). The mean mitral valve gradient (MVG) in DMR group was increased from (3.1±1.2) mmHg (1 mmHg=0.133 kPa) to (3.7±1.2) mmHg 6 months after operation (P<0.05), while there was no significant change in FMR group (P>0.05). Compared with those before operation, the N-terminal pro-B-type natriuretic peptide levels in both FMR and DMR groups were significantly lower at 6 months postoperatively (all P<0.05), and the left atrial volume index and left atrial anteroposterior diameter were also significantly lower (all P<0.05). The left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly reduced 6 months after operation in the FMR group (all P<0.05), but no significant changes were observed in the DMR group (all P>0.05). The ejection fraction was not significantly changed before and after operation in both groups (all P>0.05). The mitral regurgitation, tricuspid regurgitant, and pulmonary artery pressure were significantly reduced in both groups at 6 months postoperatively (all P<0.05).
CONCLUSIONS
TEER is effective for moderate to severe mitral regurgitation. The improve-ments in left ventricular remodeling are more pronounced in patients with FMR while the degree of mitral regurgitation is more significant in DMR patients. However, MVG elevation is more common during the follow-up.

OBJECTIVES:
To analyze the early clinical outcomes of the XcorTM 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 XcorTM 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 XcorTM 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 XcorTM 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.

OBJECTIVES:
To analyze the efficacy and safety of concomitant left atrial appendage clipping during heart valve surgery for valvular heart disease patients with atrial fibrillation.
METHODS:
Fifty-eight patients who underwent concomitant left atrial appendage clipping during cardiac valve surgery in the Second Affiliated Hospital of Nanchang University from January 2017 to June 2023 were included in the analysis, including 1 case who underwent aortic valve replacement, 49 cases who underwent mitral valve replace-ment (or valvuloplasty)+tricuspid valvuloplasty, and 8 cases who underwent double valve replacement+tricuspid valvuloplasty (3 cases combined with coronary artery bypass grafting). The patients were followed up for 3-36 months [(16.69±6.61) months] after operation, and the changes of cardiac function and the occurrence of serious adverse complications were evaluated.
RESULTS:
The cardiopulmonary bypass time ranged from 75 to 145 min [(102.50±21.03) min], and the aortic cross-clamp time ranged from 35 to 80 min [(58.02±14.63) min]. The length of postoperative intensive care unit stay was 1 to 5 days [(2.47±0.82) d], and the length of postoperative hospital stay was 7 to 22 days [(10.84±2.69) d]. Cardiac ultrasound indicated complete closure of the left atrial appendage in all cases. During the follow-up, New York Heart Association (NYHA) functional classifications were improved in 54 patients. No left atrial appendage-related bleeding events or other perioperative complications were observed; and no cerebral infarction, limb embolism events, or mortality cases occurred during the follow-up.
CONCLUSIONS
For valvular heart disease patients with atrial fibrillation, concomitant left atrial appendage clipping during cardiac valve surgery demonstrates efficacy and safety, with no severe adverse events during a medium-term follow-up.
