Insights
This case study details a complex surgical repair for simultaneous ischaemic heart disease, aortic stenosis, and left ventricular aneurysm. The successful procedure restored cardiac function and prevented embolic stroke risks.
Area of Science:
- Cardiovascular Surgery
- Cardiac Pathology
Background:
- Ischaemic heart disease and aortic stenosis pose significant risks.
- A post-infarct left ventricular aneurysm exacerbates these dangers, creating a hazardous triad.
Observation:
- A patient presented with simultaneous ischaemic heart disease, aortic stenosis, and a left ventricular aneurysm.
- This combination presents a unique and severe clinical challenge.
Findings:
- Surgical correction involved aneurysmectomy, aortic valve replacement, and coronary artery bypass grafting.
- Teflon-buttressed mattress sutures achieved direct linear closure of the aneurysm.
- Post-operative assessment showed good ventricular systolic function (LVEF 40%) and a competent aortic valve without paravalvular leaks.
Implications:
- Meticulous aneurysm thrombectomy and edge eversion are crucial to prevent embolic stroke.
- Restoring ventricular shape is vital for effective myocardial function and adequate stroke volume.
- This case demonstrates a viable surgical strategy for complex cardiac conditions.
Abstract:
Ischaemic heart disease and aortic stenosis are potentially life-threatening conditions. A post-infarct left ventricular aneurysm, when combined with the above, is particularly hazardous. We present a case where all three conditions occurred simultaneously and describe the surgical approach undertaken to attempt correction. The patient underwent aneurysmectomy together with aortic valve replacement and two-vessel coronary artery bypass grafting. The aneurysm was excised with direct linear closure of the walls using a Teflon-buttressed interrupted mattress suture technique. Post-operatively, ventricular systolic function was good (LVEF 40%) together with a well-seated aortic valve showing no paravalvular leaks. This case highlights the importance of meticulous removal of thrombus from the aneurysm and everting the edges thereby eliminating a thrombogenic surface and the risk of embolic stroke. The restorative procedure itself serves to underline the importance of ventricular shape in the effective functioning of the myocardium for sustaining an adequate stroke volume with normalized physiology.
