The Impact

Abstract Background It is recommended that breast cancer patients should undergo cardiac follow-up during chemotherapy, with clinical assessment and echocardiogram. Standard measurements are robust and reproducible, but novel echocardiography methods as global longitudinal strain (GLS) and three-dimensional (3D) echocardiography are recommended due to their superior sensitivity. These methods require high-quality images. Breast cancer surgery may lead to reduced echocardiographic image quality in this population, in addition to age, obesity and smoking. Purpose We wanted to explore the feasibility of standard and novel echo methods in an unselected breast cancer population. Methods The present study included consecutive, unselected patients referred to baseline echocardiogram at the cardio oncology outpatient clinic in a large university hospital prior to start of adjuvant chemotherapy. Data on surgery, smoking habits, age and body mass index were collected. Feasibility was defined as the presence or absence to carry out meaningful measurements of left ventricular (LV) systolic function, from standard mitral annular plane systolic excursion (MAPSE) and two-dimensional LV ejection fraction (EF), to novel GLS and 3D LVEF. Multivariable logistic regression was performed to assess the impact of relevant variables on image quality. Results 116 female patients were included. 21 % of these patients had insufficient images for novel analyses. Left sided breast implant (OR 5,77; P 0,04), age (OR 3,89; P 0,02) and daily smoking (OR 3,57; P 0,03) were found to be independently associated with insufficient image quality. Standard analyses like two-dimensional EF and MAPSE were obtainable in 99 and 97 % of the examinations, respectively. Conclusion One of five in a postoperative breast cancer population cannot undergo follow-up using novel, sensitive echocardiographic measurements. Standard measurements, however, are obtainable in almost all patients. It is therefore important that these measurements are included in cardiac follow-up during chemotherapy.

Objective:To report a case of seizure-induced takotsubo cardiomyopathy with rare etiology and rarer complications.Methods:A 50-year-old woman had multiple epileptic seizures and later developed acute heart failure complicated by ventricular fibrillation and shock. A two-dimensional echocardiogram revealed apical ballooning of the left ventricle resembling a takotsubo (a Japanese fisherman's pot used to trap octopi). The apex was also hypokinetic.Results:The hemodynamic abnormalities normalized with defibrillation, assisted ventilation, inotropic support, and pressor agents. More importantly, the apical ballooning deformity and systolic dysfunction reversed. The echocardiogram normalized three months later. A nuclear treadmill stress test was negative for ischemia.Conclusions:Apical ballooning of the left ventricle and hypokinesis are typical echocardiographic features in takotsubo cardiomyopathy, a stress-induced heart disease. It may follow severe emotional, physical, and neurologic stressors, in our rare case, grand mal seizures (0.2 % of all takotsubo disease patients). Also rare are life-threatening complications. Based on these observations, in a case with severe stress followed by acute heart failure, takotsubo cardiomyopathy should be a major diagnostic consideration. The dramatic initial triggering event, in our case an epileptic seizure, should not mask the possibility of coexisting takotsubo cardiomyopathy. Awareness of this disease, anticipation of complications, and two-dimensional echocardiography will help channel the management in the right direction.

AbstractIn contrast to hypertrophic cardiomyopathy, there has been reported no specific pattern of cardiomyocyte array in dilated cardiomyopathy (DCM), partially because lack of alignment assessment in a three-dimensional (3D) manner. Here we have established a novel method to evaluate cardiomyocyte alignment in 3D using intravital heart imaging and demonstrated homogeneous alignment in DCM mice. Whilst cardiomyocytes of control mice changed their alignment by every layer in 3D and position twistedly even in a single layer, termed myocyte twist, cardiomyocytes of DCM mice aligned homogeneously both in two-dimensional (2D) and in 3D and lost myocyte twist. Manipulation of cultured cardiomyocyte toward homogeneously aligned increased their contractility, suggesting that homogeneous alignment in DCM mice is due to a sort of alignment remodelling as a way to compensate cardiac dysfunction. Our findings provide the first intravital evidence of cardiomyocyte alignment and will bring new insights into understanding the mechanism of heart failure.

Significant Difference

Abstract Introduction Assessment of cardiac function after treatment for breast cancer relies on interval evaluation of ventricular function through echocardiography. Women who undergo mastectomy more frequently choose to undergo breast reconstruction with implant. This could impede assessment of cardiac function in those with left-sided implant. We aimed to examine whether left-sided breast reconstruction with tissue expanders (TE) affect echo image acquisition and quality, possibly affecting clinical decision-making. Methods A retrospective case-control study was conducted in 190 female breast cancer patients who had undergone breast reconstruction with TE at an urban academic center. Echocardiographic technical assessment and image quality were respectively classified as excellent/good or adequate/technically difficult by technicians; and excellent/good or adequate/poor by 2 board-certified cardiologist readers. Likelihood ratio was used to test multivariate associations between image quality and left-sided TE. Results We identified 32 women (81.3% white; mean age 48 years) with left-sided/bilateral TE, and 158 right-sided/no TE (76.6% white, mean age 57 years). In multivariable analyses, we found a statistically significant difference in technician-assessed difficulty in image acquisition between cases and controls (p = 0.01); but no differences in physician-assessed image quality between cases and controls (p = 0.09, Pearson’s r = 0.467). Conclusions Left-sided breast TE appears to affect the technical difficulty of echo image acquisition, but not physician-assessed echo image quality. This likely means that echo technicians absorb most of the impediments associated with imaging patients with breast TE such that the presence of TE has no bearing on downstream clinical decision-making associated with echo image quality.
