Surgical Ventricular Reconstruction in Ischemic Heart Failure
Summary
Surgical ventricular reconstruction encompasses a range of open and hybrid procedures designed to restore the geometry and function of the left ventricle after ischaemic injury. Following myocardial infarction, adverse remodelling characterised by thinning, dilation and aneurysm formation leads to impaired systolic performance and progressive heart failure. Reconstruction techniques aim to exclude scarred or dyskinetic segments, reduce chamber volume and re-establish a more conical ventricular shape. Classic approaches include aneurysmectomy and endoventricular patch plasty, while newer hybrid methods combine limited thoracotomy with catheter-based anchoring systems. By improving wall stress distribution and promoting favourable haemodynamics, ventricular reconstruction may enhance ejection fraction, relieve symptoms and prolong survival. Patient selection relies on multimodal imaging to define scar burden, ventricular dimensions and associated right ventricular function. Despite advances in perioperative care, the procedure remains reserved for carefully selected individuals with significant remodelling, refractory symptoms and suitable coronary anatomy.
Research from Nature Portfolio
Recent preclinical work has deployed advanced imaging to dissect molecular and structural changes in post-infarction remodelling. Combining high-resolution three-dimensional light sheet microscopy with serial echocardiography, investigators demonstrated that delayed administration of an angiotensin-converting enzyme inhibitor mitigates left ventricular dilation and hypertrophy without altering infarct size. Enhanced microvascular density in the infarct border zone correlated with preservation of ejection fraction, validating a powerful workflow for simultaneous functional and morphological assessment. This integrated platform offers a robust preclinical model to evaluate pharmacological adjuncts to surgical reconstruction.

Technical terms
Surgical ventricular reconstruction: A set of procedures that remove or exclude non-functional myocardial segments to restore ventricular shape and function.
Left ventricular aneurysm: A bulging, thinned portion of the ventricular wall that fails to contract normally following myocardial infarction.
End-systolic volume index (ESVI): The volume of blood in the left ventricle at the end of systole, normalised to body surface area, used to assess remodelling.
Continuous-flow left ventricular assist device (LVAD): A mechanical pump implanted to support or replace left ventricular function in advanced heart failure.
Dyskinetic vs. akinetic dysplasia: Dyskinetic myocardium moves paradoxically outward during systole, while akinetic tissue remains motionless.
