Cardiac haemangiomas are rare cardiac tumours that are usually asymptomatic and detected incidentally while imaging the heart with echocardiogram. Cardiovascular magnetic resonance (CMR) is a non-ionising imaging modality that allows the diagnosis of cardiac haemangiomas prior to surgery. We report a 36-year old male patient who was referred to the Adult Cardiology Clinic at the Royal Hospital, Muscat, Oman, in 2006 with a history of a left ventricle mass detected on echocardiogram. Further assessment of the mass by CMR revealed that the mass within the left ventricle apical septum contained features that were consistent with a cardiac haemangioma. Due to the surgical risk of ventricular septal defect and the stability of the mass, the patient was managed conservatively and upon followup the patient’s condition remained stable.

Careful Assessment

Magnetic resonance imaging (MRI) is a useful and safe imaging modality for examining preterm infants. However, MRI examination requires careful precautions, and infants and children are likely to require deep sedation or anesthesia to keep them still during the examination. Sedation has various risks and the greatest concern of sedation is cardiorespiratory events. In addition, delicate titration is also necessary for preterm infants because propofol pharmacokinetics is different from those in older children. We successfully completed sedation of a preterm neonate (gestational age, 32+1 weeks; birth weight, 1,970 g) with a history of frequent apnea through careful assessment and continuous monitoring. We want to suggest alternative options for airway management of the high risk of respiratory complications.

And Function

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiac disease, and its main characteristic is symmetrical or asymmetrical hypertrophy of the left ventricle and/or right ventricle. Most previous studies mainly include the left ventricle for definition of HCM, thus neglecting the right ventricle. But recently, many studies have reported the right ventricular involvement in HCM. Histopathological results showed that similar pathogenic changes in both the right and left ventricles, which suggests common myopathic processes and sarcomere genetic mutations. Cardiovascular magnetic resonance (CMR) is a gold standard imaging modality to assess heart anatomy and function and provides highly accurate and reproducible measurements. CMR is very useful in characterizing the various phenotypes of right and left ventricles in HCM. CMR also can be useful in detecting early and dominant phenotypic expression of HCM. Due to the complex geometry of the right ventricle and its retrosternal position, echocardiography may not provide accurate measurements. CMR also provides more accurate and repeatable right ventricular measurements. Thus, right ventricle evaluation along with left ventricle should routinely be done for better assessment of HCM patients.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main funding source(s): Medical University of SIlesia Background Transthoracic echocardiography (TTE) is the main imaging modality used to assess patients with chronic aortic regurgitation (AR). However, it is not possible to provide a precise quantification in all patients. Our aim was to compare TTE and cardiovascular magnetic resonance (CMR) measurements in grading AR and left ventricle (LV) remodeling. Methods A total of 51 consecutive patients with isolated AR in TTE were enrolled into the study and finally forty nine individuals (age: 57.1 (14); 61% males) underwent a non-contrast CMR (2 pts excluded for CMR contraindications). AR severity grading and LV remodeling were assessed according to the current ASE guidelines, including a semi-quantitative and quantitative parameters. All CMR studies were obtained on ecg-gated cine images acquired on 1.5T system (GE Optima MR450w, GE Healthcare, Wisconsin, USA) with a dedicated cardiac coil using a non-contrast protocol, including a quantitative approach (phase-contrast velocity  encoded imaging). Results Most of the study patients showed mild symptoms (NYHA I/II/III – 55%/38%/7%; CCS 0/I/II/III/IV – 79%/2%/12%/6%) and typical cardiovascular risk factors: hypertension (83%), dyslipidemia (91%), diabetes (12%) and obesity (16%). Twenty patients (40%) showed combined AV disease and 14 patients (28,5%) had a bicuspid AV. The AR jets were central (53%) or eccentric (47%) and multiple in 7 cases (14%). The inter-modality agreement (TTE-CMR) in AR grading was high in mild AR (91%) and low in mild-to-moderate (12%), moderate-to-severe (10%) and severe (20%) AR. The comprehensive quantitative grading with AR volume (AR vol) and regurgitant fraction (RF) were measurable in TTE in 24 cases and showed a significant association with CMR parameters (AR vol: r = 0.75; p < 0.001 and RF: r = 0.55; p < 0.01). Moreover, CMR revealed significantly larger LV end-diastolic volumes (EDV) (185,5 ± 61ml vs 158,4 ± 61ml; p = 0.03) and a trend towards higher left ventricle ejection fraction (59 ± 8 vs 56 ± 8%; p = 0.08). The association of AR vol and LV EDV was stronger in CMR (r = 0.85; p < 0.0001) compared to TTE (r = 0.6; p = 0.001). Conclusions CMR provides a comprehensive assessment of AR severity and LV remodeling with a moderate agreement with TTE.

Abstract Background Primary cardiac tumours arising from smooth muscle cells are said to be very rare in the literature. Primary leiomyoma of the heart particularly in men is extremely rare. To the best of my knowledge, there are only two reported cases of boys with primary leiomyoma of the heart in the English literature. Most of leiomyoma tumours involving the heart reported in the literature are a result of cardiac extensions of intravenous leiomyomatosis through the inferior vena cava. Case presentation A case of left ventricular primary leiomyoma in a 74-year-old male is reported. He had no known previous history of heart disease but he died suddenly and unexpectedly. At autopsy, the heart measured 420 gm and when it was opened, a solid tumour of size 4 × 3 × 2 cm involving the lower left ventricle on the anterior aspect of the heart was found. The tumour was extending to the left ventricular septum and was growing by protruding into the left ventricle chamber which finally was confirmed histopathologically to be a leiomyoma. Conclusion Cardiac benign tumours are rare and can be life threatening because of embolization following their detachment which is manifested clinically by stroke. Additionally, they are clinically asymptomatic; therefore, they cannot be easily detected. In case of clinical suspicion, echocardiography and other imaging diagnostic tests should be used to confirm presence of a tumour.

Abstract Purpose According to current ESC guidelines, mid-range ejection fraction (mrEF) might represent a separate subgroup of patients with distinct underlying characteristics, prognosis and treatment response. Cardiac magnetic resonance (CMR) is the gold standard for measuring volumes, mass and ejection fraction of the heart. We aimed to find long-term prognostic value of various CMR parameters in patients mrEF. Methods 137 patients with mrEF underwent CMR (1.5T) between 2012 and 2018 and were consecutively included. Volumes, mass and ejection fraction were assessed using short axis SSFP images and the Simpson method (using commercially available software). Myocardial fibrosis was determined by late gadolinium enhancement (LGE). Clinical parameters after a median of 762 (230–1315 days) were recorded. Patients with other significant cardiac affection rather than mrEF were excluded (pre-capillary pulmonary hypertension and significant valve disease). The primary endpoint was defined as a combined outcome of all-cause death or heart failure decompensation requiring in-hospital admission. Results Mean age was 63.0±12.4 years. 76.6% were males. Mean left ventricle ejection fraction (LVEF) was 45±2.69%. Main aetiologies were ischemic (46%), idiopathic (32.12%), myocarditis (9.5%), tachycardiomyopathy (6.57%) enolic (2.2%) stress cardiomyopathy (0.7%) and others (2.9%). A combined model for predicting outcomes in patients with mrEF using CMR parameters was obtained. This model was able to predict 32.7% (coefficient of determination, R-squared) of the adverse events (p<0.01). Significant CMR parameters and results are shown on table 1. Combined model for predicting outcomes in patients with mrEF using CMR parameters Variable p value iRVEDV (indexed right ventricular end-diastolic volume) <0.01 RVEF (right ventricle ejection fraction 0.03 iRVESV (indexed right ventricular end-systolic volume) <0.01 Presence of late enhancement (yes/no) 0.09 iLA (indexed left atrial) Volume <0.01 iLV (indexed left ventricle) mass <0.01 Variables and their significance are shown individually. Conclusions In patients with mid-range ejection fraction, RV volumes and ejection fraction, as well as LV mass and LA volume, were significant predictors of worse outcomes in a combined model. If supported by further studies, these findings may help the clinician select the patients with higher risk of complications and in need of a closer follow-up.

Abstract Background  Magnetic resonance imaging (MRI) is increasingly becoming the imaging modality of choice for many clinical disorders due to superior image quality and absence of radiation. However, access to MRI remains limited for most patients with cardiac implantable electronic devices due to potential safety concerns. In line with guidelines, there is no absolute contraindication to perform MRI, but warrants careful risk-benefit assessment. Case summary  A 59-year-old man was admitted with a 5-day history of central chest pain and few week’s history of general malaise, dry cough, and breathlessness. Electrocardiogram confirmed complete atrioventricular block (CAVB). A slight increase in cardiac enzyme was noted. Coronary angiogram revealed atheromatous changes, but no obstructive coronary lesion. A temporary transvenous pacemaker was inserted. Transthoracic echocardiogram confirmed a dilated left ventricle with severely reduced left ventricular function. To facilitate diagnosis (hence prognosis), management and mobilization, investigation with cardiovascular magnetic resonance (CMR) was warranted but contraindicated by the temporary transvenous pacemaker. An active fixation pacemaker lead was therefore placed in the right ventricle via percutaneous puncture of the right subclavian vein and connected to a pulse generator, both secured to the skin with sutures and adhesive medical dressing. Appropriate device programming and close patient monitoring ensured that CMR could be performed without any adverse effects. A diagnosis of acute myocarditis was confirmed. Regular device interrogation during an extended 3-week period with temporary pacing ruled out any device failure. As there was no resolution of CAVB, the patient received a dual-chamber pacemaker. Discussion  Cardiovascular magnetic resonance was feasible and safely performed on a patient with a temporary permanent external pacemaker system using a standard screw-in pacing lead and a regular pulse generator fixed to the skin. Although more studies are needed for generalizability, CMR may be used in highly selected patients with a temporary pacemaker.
