“…We appreciate that cMRI has greater accuracy than GHPS (and echocardiography) at non‐invasively visualising regions of biventricular myocardial scar and correlates well with bipolar electroanatomic voltage scar 30 ; however, considering the retrospective nature of this study and timeline of recruitment, it was not available but should be utilised in future prospective work. Although GHPS is not routinely utilised for evaluation of cardiac function post‐STEMI, it has been found to correlate well with transthoracic echocardiography with regard to ejection fraction and regional wall motion abnormality and with less interuser variability 31,32 …”

BackgroundVentricular arrhythmia (VA) is the most common cause of sudden cardiac death post‐ST elevation myocardial infarction (STEMI). Ventricular tachycardia (VT) may be inducible in electrophysiology studies (EPS) early (<40 days) post‐STEMI. Whether it originates from the infarct site remains unknown. We examined the correlation between inducible VT and infarct location post‐STEMI.AimsTo investigate the correlation between inducible VT and infarct location post‐STEMI.MethodsWe retrospectively analysed 46 patients from 2005 to 2017 with STEMI who underwent early programmed ventricular stimulation through EPS (>48 h post‐STEMI and <40 days from admission). Gated heart pool scans were used to visualise infarct scar regions, and VT exit sites were derived from induction 12‐lead electrocardiography. Patients were followed up for primary outcomes of recurrent VA and all‐cause mortality.ResultsForty‐six patients were included for analysis, with 50 uniquely induced VT exit sites. Mean left ventricular ejection fraction was 30 ± 8.7% and 22% had impaired right ventricular ejection fraction. Mean time from presentation to EPS was 16 ± 31.3 days. Of the induced VT, 44 (88%) were from within scar and scar‐border regions, whereas 6 (12%) of the induced VT were found to be remote to imaging‐derived scar. Over a median follow‐up period of 75 months, 6 (13%) patients died, and 7 (15%) patients had recurrent VA. No deaths occurred in patients with remote VT.ConclusionThe majority of early inducible post‐infarct VT arises from acute myocardial scar; however, a small portion arises from sites remote from scars with a possible focal aetiology.

“…Various noninvasive imaging modalities are available for assessing biventricular function, including contrast-enhanced echocardiography, three-dimensional echocardiography (3DE), and gated heart-pool scan (GHPS) [50]. Studies exploring the concordance among these modalities in measuring LVEF and RVEF within the same patient cohort reveal discrepancies, with Pearson's correlation coefficients ranging from 0.64 to 0.91 for LVEF and 0.27 to 0.86 for RVEF measurements [50]. This highlights the need for careful consideration in clinical management and sequential patient follow-up.…”

Advanced heart failure (AHF) presents a complex landscape with challenges spanning diagnosis, management, and patient outcomes. In response, the integration of multimodality imaging techniques has emerged as a pivotal approach. This comprehensive review delves into the profound significance of these imaging strategies within AHF scenarios. Multimodality imaging, encompassing echocardiography, cardiac magnetic resonance imaging (CMR), nuclear imaging and cardiac computed tomography (CCT), stands as a cornerstone in the care of patients with both short- and long-term mechanical support devices. These techniques facilitate precise device selection, placement, and vigilant monitoring, ensuring patient safety and optimal device functionality. In the context of orthotopic cardiac transplant (OTC), the role of multimodality imaging remains indispensable. Echocardiography offers invaluable insights into allograft function and potential complications. Advanced methods, like speckle tracking echocardiography (STE), empower the detection of acute cell rejection. Nuclear imaging, CMR and CCT further enhance diagnostic precision, especially concerning allograft rejection and cardiac allograft vasculopathy. This comprehensive imaging approach goes beyond diagnosis, shaping treatment strategies and risk assessment. By harmonizing diverse imaging modalities, clinicians gain a panoramic understanding of each patient’s unique condition, facilitating well-informed decisions. The aim is to highlight the novelty and unique aspects of recently published papers in the field. Thus, this review underscores the irreplaceable role of multimodality imaging in elevating patient outcomes, refining treatment precision, and propelling advancements in the evolving landscape of advanced heart failure management.

ObjectiveTo evaluate the utility of two-dimensional multiplanar speckle tracking strain to assess for cardiotoxicity post allogenic bone marrow transplantation (BMT) for haematological conditions.MethodsCross-sectional study of 120 consecutive patients post-BMT (80 pretreated with anthracyclines (BMT+AC), 40 BMT alone) recruited from a late effects haematology clinic, compared with 80 healthy controls, as part of a long-term cardiotoxicity surveillance study (mean duration from BMT to transthoracic echocardiogram 6±6 years). Left ventricular global longitudinal strain (LV GLS), global circumferential strain (LV GCS) and right ventricular free wall strain (RV FWS) were compared with traditionl parameters of function including LV ejection fraction (LVEF) and RV fractional area change.ResultsLV GLS (−17.7±3.0% vs −20.2±1.9%), LV GCS (−14.7±3.5% vs −20.4±2.1%) and RV FWS (−22.6±4.7% vs −28.0±3.8%) were all significantly (p=0.001) reduced in BMT+AC versus controls, while only LV GCS (−15.9±3.5% vs −20.4±2.1%) and RV FWS (−23.9±3.5% vs −28.0±3.8%) were significantly (p=0.001) reduced in BMT group versus controls. Even in patients with LVEF >53%, ~75% of patients in both BMT groups demonstrated a reduction in GCS.ConclusionMultiplanar strain identifies a greater number of BMT patients with subclinical LV dysfunction rather than by GLS alone, and should be evaluated as part of post-BMT patient surveillence. Reduction in GCS is possibly due to effects of preconditioning, and is not fully explained by AC exposure.
