Abstract: Background Lipoprotein(a) [Lp(a)] is a genetically inherited lipid marker associated with an increased risk of atherosclerotic cardiovascular disease (ASCVD).Unlike LDL-C, Lp(a) is minimally responsive to lifestyle modification or statins.Management becomes especially challenging in patients with statin intolerance and co-existing cardiac conditions.PCSK9 inhibitors offer a therapeutic option by modestly lowering Lp(a) levels in addition to LDL-C.This case highlights the management of a patient with elevated Lp(a), statin intolerance, and a history of transcatheter aortic valve implantation (TAVI).Case Presentation A 65-year-old female with a history of chronic coronary syndrome and severe aortic valve stenosis underwent successful TAVI with a Sapien 3 bioprosthetic valve in November 2022.She was diagnosed with familial hyperlipoproteinemia and significantly elevated Lp(a) levels (801 mmol/L), alongside intolerance to high-dose statins.Due to her high cardiovascular risk, she was enrolled in the RDTL drug reimbursement program and initiated on evolocumab (a PCSK9 inhibitor) at 140 mg every 14 days.At follow-up in December 2024, clinical assessment revealed stable cardiovascular status.Echocardiography showed preserved left ventricular ejection fraction (EF 60%) with good function of the implanted aortic valve.Blood pressure was 120/70 mmHg, ECG Med.Sci.Forum 2026, 44, 1 https://doi.org/10.3390/msf2026044001demonstrated sinus rhythm, and her Lp(a) level had decreased to 585 mmol/L, indicating a partial but significant response to therapy.Her medications included perindopril, metoprolol, rosuvastatin/ezetimibe (5/10 mg), metformin, clopidogrel, and evolocumab.Conclusion This case illustrates the long-term benefit of PCSK9 inhibitor therapy in a statinintolerant patient with elevated Lp(a) and post-TAVI status.Partial biochemical response and clinical stability highlight the role of targeted lipid-lowering therapy and structured follow-up in managing genetically driven dyslipidemia in high-risk cardiac patients. 1.2.
