Despite substantial advances in the imaging techniques and pathophysiological understanding over the last decades, identification of the underlying causes of left ventricular hypertrophy by means of echocardiographic examination remains a challenge in current clinical practice. The longitudinal strain bull’s eye plot derived from 2D speckle tracking imaging offers an intuitive visual overview of the global and regional left ventricular myocardial function in a single diagram. The bull’s eye mapping is clinically feasible and the plot patterns could provide clues to the etiology of cardiomyopathies. The present review summarizes the longitudinal strain, bull’s eye plot features in patients with various cardiomyopathies and concentric left ventricular hypertrophy and the bull’s eye plot features might serve as one of the cardiac workup steps on evaluating patients with left ventricular hypertrophy.

Aims The role of diastolic dysfunction (DD) in prognostic evaluation in heart failure (HF) patients with impaired systolic function remains unclear. We investigated the impact of echocardiography‐defined DD on survival in HF patients with mid‐range (HFmrEF, EF 41–49%) and reduced ejection fraction (HFrEF, EF < 40%). Methods and results A total of 2018 consecutive hospitalized HF patients were retrospectively included and divided in two groups based on baseline EF: HFmrEF group (n = 951, aged 69 ± 13 years, 74.2% male) and HFrEF group (n = 1067, aged 68 ± 13 years, 76.3% male). Clinical data were collected and analysed. All patients completed ≥1 year clinical follow‐up. The primary endpoint was defined as all‐cause death (including heart transplantation) and cardiovascular (CV)‐related death. All‐cause mortality (30.8% vs. 24.9%, P = 0.003) and CV mortality (19.1% vs. 13.5%, P = 0.001) were significantly higher in the HFrEF group than the HFmrEF group during follow‐up [median 24 (13–36) months]. All‐cause mortality increased in proportion to DD severity (mild, moderate, and severe) in either HFmrEF (17.1%, 25.4%, and 37.0%, P < 0.001) or HFrEF (18.9%, 30.3%, and 39.2%, P < 0.001) patients. The risk of all‐cause mortality [hazard ratio (HR) = 1.347, P = 0.015] and CV mortality (HR = 1.508, P = 0.007) was significantly higher in HFrEF patients with severe DD compared with non‐severe DD after adjustment for identified clinical and echocardiographic covariates. For HFmrEF patients, severe DD was independently associated with increased all‐cause mortality (HR = 1.358, P = 0.046) but not with CV mortality (HR = 1.155, P = 0.469). Conclusions Echocardiography‐defined severe DD is independently associated with increased all‐cause mortality in patients with HFmrEF and HFrEF.

Background: This study aimed to explore the value of cardiac biomarker [serum high sensitive troponin T (hs-TNT) and N-terminal pro-brain natriuretic peptide (NT-proBNP)] measurement in the differential diagnosis of infiltrative cardiomyopathy patients [Friedreich’s ataxia (FA), Fabry disease (FD) and light-chain (AL) cardiac amyloidosis (CA)] with preserved left ventricular (LV) systolic function. Methods: Between 2012 and 2014, all consecutive patients presenting at our center with infiltrative cardiomyopathy and concomitant symmetrical LV hypertrophy as well as preserved LV systolic function were included in this study. Serum hs-TNT and NT-proBNP, morphologic and functional features derived from echocardiography and cardiac magnetic resonance imaging (cMRI) examinations were compared among these patients. Results: A total of 57 patients (FA 20, FD 23 and CA 14) were included. Hs-TNT and NT-proBNP levels were significantly higher in the CA group [median: hs-TNT 98 pg/mL, NT-proBNP 4,110 pg/mL] than in the FA group [hs-TNT 14 pg/mL, NT-proBNP 40 pg/mL] and FD group [hs-TNT 18 pg/mL, NT-proBNP 131 pg/mL, both P60 pg/mL (sensitivity 0.79, specificity 0.93) and NT-proBNP >1,000 pg/mL (sensitivity 0.91, specificity 0.93) excellently differentiated CA from FA and FD. Conclusions: Increased hs-TNT and NT-proBNP levels are suggestive of CA diagnosis among patients with infiltrative cardiomyopathy and preserved LV ejection fraction.

Aortic valve stenosis is a common finding diagnosed with high sensitivity in transthoracic echocardiography, but the examiner often finds himself confronted with uncertain results in patients with moderate pressure gradients and concomitant systolic heart failure. While patients with true-severe low-gradient aortic valve stenosis with either reduced or preserved left ventricular systolic function are primarily candidates for valve replacement, there is a relevant proportion of patients with pseudo-severe aortic valve stenosis anticipated not to benefit but actually rather deteriorate by interventional therapy or surgery. In this article we present a case report of a male patient with pseudo-severe aortic valve stenosis due to cardiac amyloidosis highlighting the diagnostic schedule. The patient underwent stress echocardiography because of discrepant findings in transthoracic echocardiography and cardiac catheterization regarding the severity of aortic valve stenosis. After evaluation of the results, it became clear that he had a need for optimum heart failure medication and implantation of a cardiac resynchronization therapy defibrillator. Due to the pitfalls in conventional as well as invasive diagnostics at rest, Stress echocardiography should be considered part of the standard optimum diagnostic spectrum in all unclear or borderline cases in order to confirm the correct diagnosis and constitute optimal therapy.
