4. Use of Cardiac MRI to Assess Antitumor Efficacy of Everolimus in Sporadic Cardiac Rhabdomyoma. (PubMed)

Use of Cardiac MRI to Assess Antitumor Efficacy of Everolimus in Sporadic Cardiac Rhabdomyoma. Cardiac rhabdomyoma is the most common neonatal cardiac tumor and is typically associated with tuberous sclerosis complex (TSC). Although these tumors may naturally regress, some patients require surgical resection because of cardiac instability. If not fully resected, patients may also require medical therapy to improve their hemodynamics. Everolimus, a mammalian target of rapamycin inhibitor, has (...) shown promise in reducing rhabdomyoma in patients with TSC, but the drug's impact in patients without TSC has not been reported. Monitoring of tumor response has typically been limited to echocardiograms, which is not ideal given inherent difficulties in three-dimensional measurements. We report a case of sporadic cardiac rhabdomyoma in a neonate treated with everolimus resulting in tumor regression as documented by cardiac MRI. While on everolimus, our patient had an increased incidence

5. Clinical safety and performance of a MRI conditional pacing system in patients undergoing cardiac MRI. (PubMed)

Clinical safety and performance of a MRI conditional pacing system in patients undergoing cardiac MRI. Utilization of cardiac magnetic resonance imaging (cMRI) as an imaging modality in clinical practice is rapidly increasing. More evidence from randomized studies establishing clinical safety and performance of pacing systems in patients undergoing a cMRI scan is needed.The purpose of this prospective, multicenter, randomized study was to demonstrate safety and efficacy of the Accent MRI™ (...) conditional pacing systems (St. Jude Medical, St. Paul, MN, USA) in patients undergoing cMRI scan.Patients (n  =  283) indicated for dual-chamber pacemaker implant were randomized to either the MRI Group (MG) (n  =  140) or the Control Group (CG) (n  =  143) after successful device implantation of the Accent MRI™ system. Clinical evaluation and device interrogation were performed at pre- and post-MRI scan, and 1 month post-MRI for all patients. At 9-12 weeks postimplant, patients in MG underwent

12. Prognostic Role of Cardiac MRI and Conventional Risk Factors in Myocardial Infarction With Nonobstructed Coronary Arteries. (PubMed)

Prognostic Role of Cardiac MRI and Conventional Risk Factors in Myocardial Infarction With Nonobstructed Coronary Arteries. This study sought to assess the prognostic impact of cardiovascular magnetic resonance (CMR) and conventional risk factors in patients with myocardial infarction with nonobstructed coronaries (MINOCA).Myocardial infarction with nonobstructed coronary arteries (MINOCA) represents a diagnostic dilemma, and the prognostic markers have not been clarified.A total of 388 (...) consecutive patients with MINOCA undergoing cardiac magnetic resonance (CMR) assessment were identified retrospectively from a registry database and prospectively followed for a primary clinical endpoint of all-cause mortality. A 1.5-T CMR was performed using a comprehensive protocol (cines, T2-weighted, and late gadolinium enhancement sequences). Patients were grouped into 4 categories based on their CMR findings: myocardial infarction (MI) (embolic/spontaneous recanalization), myocarditis

13. Deep Learning for Diagnosis of Chronic Myocardial Infarction on Nonenhanced Cardiac Cine MRI. (PubMed)

Deep Learning for Diagnosis of Chronic Myocardial Infarction on Nonenhanced Cardiac Cine MRI. Background Renal impairment is common in patients with coronary artery disease and, if severe, late gadolinium enhancement (LGE) imaging for myocardial infarction (MI) evaluation cannot be performed. Purpose To develop a fully automatic framework for chronic MI delineation via deep learning on non-contrast material-enhanced cardiac cine MRI. Materials and Methods In this retrospective single-center (...) study, a deep learning model was developed to extract motion features from the left ventricle and delineate MI regions on nonenhanced cardiac cine MRI collected between October 2015 and March 2017. Patients with chronic MI, as well as healthy control patients, had both nonenhanced cardiac cine (25 phases per cardiac cycle) and LGE MRI examinations. Eighty percent of MRI examinations were used for the training data set and 20% for the independent testing data set. Chronic MI regions on LGE MRI were

14. Usefulness of 4D-Flow MRI in Mapping Flow Distribution Through Failing Fontan Circulation Prior to Cardiac Intervention. (PubMed)

Usefulness of 4D-Flow MRI in Mapping Flow Distribution Through Failing Fontan Circulation Prior to Cardiac Intervention. We report a case of a 23-year-old male with failing Fontan circulation who was taken to the catheterization lab to better evaluate the Fontan circulation and hemodynamics. Catheterization revealed arteriovenous malformations exclusively present in the right lung leading to the consideration of placing stents to direct the inferior vena cava flow through the Fontan circuit (...) to the right pulmonary artery (RPA), thus increasing the RPA concentration of the hepatic factor. However, comprehensive 4D-Flow MRI analyses indicated sufficient distribution of the hepatic flow between branch pulmonary arteries, and consequently no further invasive intervention to redirect hepatic flow was performed.

15. Cardiac MRI improves cardiovascular risk stratification in hazardous occupations. (PubMed)

Cardiac MRI improves cardiovascular risk stratification in hazardous occupations. The benefit of cardiovascular magnetic resonance Imaging (CMR) in assessing occupational risk is unknown. Pilots undergo frequent medical assessment for occult disease, which threatens incapacitation or distraction during flight. ECG and examination anomalies often lead to lengthy restriction, pending full investigation. CMR provides a sensitive, specific assessment of cardiac anatomy, tissue characterisation (...) , perfusion defects and myocardial viability. We sought to determine if CMR, when added to standard care, would alter occupational outcome.A retrospective review was conducted of all personnel attending the RAF Aviation Medicine Consultation Service (AMCS) for assessment of a cardiac anomaly, over a 2-year period. Those undergoing standard of care (history, examination, exercise ECG, 24 h-Holter and transthoracic echocardiography), and those undergoing a CMR in addition, were identified. The influence

16. Cardiac MRI Evaluation of Neonatal Bronchopulmonary Dysplasia Associated Pulmonary Hypertension. (PubMed)

Cardiac MRI Evaluation of Neonatal Bronchopulmonary Dysplasia Associated Pulmonary Hypertension. Patients with bronchopulmonary dysplasia (BPD)-associated pulmonary hypertension (PH) have increased morbidity and mortality. Noninvasive assessment relies on echocardiograms (echo), which is technically challenging in this population. Improved assessment could augment decisions regarding PH therapies.We hypothesized that neonatal cardiac magnetic resonance imaging (MRI) will correlate with BPD (...) severity and predict short term clinical outcomes, including need for PH therapies for infants with BPD.52 infants (31 severe BPD, 9 moderate BPD, and 12 with either mild or no BPD) were imaged between 39 and 47 weeks post-menstrual age on a neonatal-sized, NICU-sited 1.5T MR scanner. MR left-ventricular eccentricity index (MR-EI), main pulmonary artery to aorta diameter (PA/AO) ratio, and pulmonary arterial blood flow (PBF) were determined. Echos obtained for clinical indications were reviewed. MRI

17. Left Atrial Fibrosis Assessed with Cardiac MRI in Patients with Paroxysmal and Those with Persistent Atrial Fibrillation. (PubMed)

Left Atrial Fibrosis Assessed with Cardiac MRI in Patients with Paroxysmal and Those with Persistent Atrial Fibrillation. Background Electrophysiology studies have demonstrated that left atrial late gadolinium enhancement (LGE) is associated with the chronicity of atrial fibrillation (AF). To date, cardiac MRI has been used to assess the extent of atrial LGE but not the distribution pattern of LGE in the left atrium. Purpose To determine whether the MRI pattern of left atrial fibrosis (...) is associated with the chronicity of AF. Materials and Methods This retrospective study included patients with AF who underwent LGE MRI between June 2017 and May 2018. The presence of left atrial LGE was assessed at nine left atrial segments; the extent was determined by the number of segments involved. According to the chronicity of AF, patients were separated into paroxysmal AF (PAF) and persistent AF (PeAF) groups. The location and extent of left atrial LGE were compared between PAF and PeAF by using
