Article Synopsis
- Transcatheter valve-in-valve (VIV) and valve-in-ring (VIR) therapies for failing mitral bioprosthetic valves are being researched to understand their effectiveness and safety over time.
- A meta-analysis reviewed 34 studies involving 7,047 patients to assess short and long-term outcomes, focusing on complications like mortality, stroke, and procedural success rates.
- Findings indicated high success rates of 94.8% for VIV and 80.5% for VIR, with varying short-term mortality and stroke risks across VIV, VIR, and traditional redo surgical mitral valve replacements (SMVR).
Given the high risk of peri-operative morbidity and mortality associated with open repair, endovascular repair for thoraco-abdominal aneurysms is increasingly performed. This study aims to describe mid to long-term results for patients who were treated with COOK Custom-Made Endograft Device at a single Southeast Asian tertiary centre. Mid to long-term results of patients treated from 2012 to 2022 were retrospectively reviewed.

- This updated meta-analysis examines the effectiveness and safety of the SENTINEL Cerebral Protection System during transcatheter aortic valve implantation (TAVI), revealing mixed results across various studies.
- The analysis included 15 studies with over 294,000 patients, finding significant reductions in mortality and strokes (both all and disabling) when using the SENTINEL device, especially in studies focusing on outcomes within 30 days.
- Despite positive findings, there was notable variability in outcome results, particularly for mortality and overall stroke rates among the studies, indicating a need for further research to clarify these differences.
Introduction: Data on patients with small aortic annuli (SAA) undergoing transcatheter aortic valve implantation (TAVI) are limited. We aim to describe the impact of aortic annular size, particularly SAA and TAVI valve type on valve haemodynamics, durability and clinical outcomes.
Method: All patients in National Heart Centre Singapore who underwent transfemoral TAVI for severe symptomatic native aortic stenosis from July 2012 to December 2019 were included.
Purpose: The exact significance of type 2 endoleaks (T2ELs) and the indication and efficacy of treatment are widely debated. We report our experience with managing T2ELs in a tertiary Asian centre.
Materials And Methods: This was a retrospective study of patients who underwent endovascular abdominal aortic aneurysm repair (EVAR) between February 2006 and December 2016.
Background: Left ventricular assist device (LVAD) associated infections (LVADIs) have substantial morbidity and mortality. We aim to describe the incidence and epidemiology of LVADIs in an Asian cohort. This is currently not well studied.

A single-center, retrospective study of 127 patients who underwent VA-ECMO for cardiogenic shock between January 2003 and December 2017 was conducted. Eighty-three (65%) patients survived to weaning or bridging therapy.

However, complications such as coronary artery dissection, coronary perforation, retrograde aortic dissection, arrhythmias, and acute coronary syndrome still occur with resulting mortality rates of up to 4.2% in complex interventions.
