Background:
Cardiovascular diseases are a major cause of global morbidity and mortality, with a high burden in low- and middle-income countries (LMICs). Limited access to cardiac catheterisation services contributes to poor health outcomes. This study reviewed catheterisation procedures, indications and outcomes in a government-owned Nigerian tertiary hospital.
Materials and Methods:
A retrospective review of all diagnostic and interventional procedures performed at the Lagos State University Teaching Hospital cardiac catheterisation laboratory between July 2022 and October 2025 was conducted. Data on patient demographics, procedures, anaesthetic techniques, indications and outcomes were extracted from the laboratory register and analysed using descriptive statistics.
Results:
A total of 588 procedures were performed. Mean patient age was 57.09 ± 16.62 years, with a slight male predominance (52.7%). Most procedures were conducted under local anaesthesia (72.6%). The most frequent procedures were inferior vena cava filter insertion (18.5%), coronary angiography (16.2%), percutaneous coronary intervention (15.8%) and pacemaker implantation (14.5%). Commonest indications were acute coronary syndrome (30.8%), venous thromboembolism (21.6%) and arrhythmias/conduction abnormalities (16.2%). Procedural volume increased progressively over the study period, with gradual expansion from predominantly diagnostic to more therapeutic procedures. Procedural success was high across all categories, with three deaths recorded (0.51%).
Conclusion:
This study demonstrates that cardiac catheterisation services can be safely and effectively delivered in a government-owned tertiary hospital within an LMIC. Strategic investment in establishing and expanding cardiac catheterisation is imperative to strengthen cardiovascular care delivery across the LMICs.
