NUMBER 17-09: CONCEALED RIGHT VENTRICULAR INFARCTION REVEALED BY CARDIAC MRI

A 59 year old male patient, diabetic, hypertensive presented with a non ST-segment elevation myocardial infarction (NSTEMI) (Image 1). The peak troponin I was 5.9 ng/ml (reference level up to 0.02 ng/ml). Coronary angiography, performed within four hours from the onset of chest pain, showed a significant proximal left anterior descending (LAD) artery lesion for which two drug eluting stents were deployed. The right coronary artery (RCA) was dominant with sluggish flow and an insignificant proximal lesion. No stents or angioplasty were performed on the RCA (Movie 1,2). ECG was recorded after catheterization (Image 2).

 

NUMBER 17-08: intra-myocardial haemangioma mimicking hypertrophic cardiomyopathy-evaluation by multimodality imaging

A 57-year-old female presented with atypical chest pain. Her past medical history was unremarkable. Initial ECG (Figure 1) revealed inferolateral T wave inversion without evidence of left ventricle hypertrophy by voltage criteria; however, serial cardiac enzymes were negative.  

Acute coronary syndrome was ruled out and the patient was referred for stress echocardiography. The stress echocardiogram revealed normal LV size and systolic function with no resting or inducible regional wall motion abnormality. However there was an incidental finding of asymmetric thickening of the distal inter-ventricular septum raising suspicion for atypical hypertrophic cardiomyopathy.
 

NUMBER 17-07: invisible cardiac lesion

A 43 year old female with a past medical history significant for hypertension and mild rheumatoid arthritis and no known cardiac disease experienced the sudden onset of chest pain, malaise, and pre-syncope at an airport. Paramedics were alerted and she was found to have inferior ST- segment elevations on an ECG (see Figure 1). The patient was immediately taken to the nearest cardiac catheterization laboratory and was found to have no significant coronary artery lesions. Her peak CK-MB was in the 50s ng/mL and her peak Troponin was 15 ng/mL. A transthoracic echocardiogram demonstrated an inferior wall motion abnormality and a left ventricular ejection fraction of 35-45% (see Figures 2-6). Her symptoms and inferior ST segment elevations subsequently resolved. She was diagnosed with coronary vasospasm and treated with diltiazem, carvedilol, aspirin, clopidogrel, nitroglycerin, simvastatin, and lisinopril. After discharge, she participated in cardiac rehabilitation but reported low energy and fluid retention that was managed with low-dose diuretics.

NUMBER 17-06: UNEXPECTED JEOPARDY: CMR IN ATYPICAL CHEST PAIN BUT CHRONIC AORTIC DISSECTION WITH CARDIAC SCHWANNOMA

A 60-year-old, obese woman with diabetes and hypertension presented with dyspnea on exertion and atypical chest pain for weeks. The physical examination was unremarkable. No ischemic changes were observed on the electrocardiogram. The sensitive Troponin-T level was less than 50.0 ng/L (0.0-100.0). 

NUMBER 17-05: CARDIOVASCULAR MAGNETIC RESONANCE IMAGING OF A RIGHT ATRIAL MASS - A CASE REPORT

A 71-year old woman, without relevant medical history, initially presented with progressive dyspnea and orthopnea due to new onset heart failure (New York Heart Association functional class III). Her blood pressure at admission was 170/105 mmHg. A chest X-ray revealed cardiomegaly and pulmonary edema. A transthoracic echocardiogram was performed and moderately reduced left ventricular function and an echodense mass in the right atrium were observed. For differentiation of various etiologies and diagnosis of the mass, cardiovascular magnetic resonance (CMR) imaging was the next step in the diagnostic strategy.

NUMBER 17-04: AORTITIS MASQUERADING AS PERICARDIAL EFFUSION

A 43-year-old female with a history of asthma and uterine fibroids presented with shortness of breath. She reported chest tightness and was awakened from sleep with chest pain that radiated down her left arm. She had no prior history of cardiac diseases. There was recent history of fever, and productive cough.

Contrast enhanced chest computed tomography showed a large circumferential pericardial effusion measuring 2.3 cm. Since she demonstrated a viral prodrome 3 days prior, viral pericarditis was the initial working diagnosis. A follow up echocardiogram 1 week later showed a decrease in the size of the pericardial effusion without steroid therapy. The patient was asymptomatic 1 week after being discharged from the hospital, and an echocardiogram demonstrated complete resolution of the prior pericardial effusion.

NUMBER 17-03: CONGENITAL MALFORMATION OF THE CORONARY DRAINAGE SYSTEM AND TRABECULAR ARCHITECTURE DETECTED BY CARDIOVASCULAR MAGNETIC RESONANCE

A 55-year-old Caucasian female presented with typical angina-like symptoms. Cardiovascular examination revealed a diastolic murmur, loudest at the left sternal edge. Her past medical history included mild hypercholesterolaemia only. Electrocardiography showed sinus rhythm with no ischaemic changes.

Coronary angiography showed unobstructed but markedly dilated high flow coronary arteries draining directly into the left ventricle (LV) through a plexus of small vessels arising from both coronaries (coronary-cameral communications). This mimicked aortic regurgitation on aortography (Figure 2; prompt LV opacification but not through the valve). No epicardial venous system enhanced.
 

NUMBER 17-02: CARDIAC INVOLVEMENT IN EOSINOPHILIC GRANULOMATOSIS WITH POLYANGIITIS

A 34 year old female presented with a history of loss of appetite, unintended weight loss, and heart failure. Her past history was remarkable for a diagnosis of eosinophilic polyangiitis (EGPA). She also had a prior bout of middle cerebral artery syndrome earlier in the year of uncertain etiology, although a coexisting PFO was found and thought to possibly represent a source of paradoxical embolism. A CT of the chest was performed to evaluate suspected pulmonary involvement, and demonstrated left ventricular enlargement. A transthoracic echocardiogram depicted a thrombus in the left ventricle.

A CMR exam was then performed to further evaluate this finding, assess left ventricular function, and determine possible cardiac involvement by EGPA.
 

NUMBER 17-01: LARGE PERICARDIAL BRONCHOGENIC DUPLICATION CYST: UTILITY OF CARDIAC MRI IN DIAGNOSIS OF A RARE ENTITY

A 31 month old female was diagnosed with a large secundum atrial septal defect (ASD) following evaluation for a murmur as neonate. At that time, a separate “third chamber” was noted that appeared contiguous with the lateral left atrium that was believed to represent a cor triatriatum membrane. One pulmonary vein was seen draining into the left atrium. The other pulmonary veins were thought to drain into the “third chamber” however transthoracic echocardiography never definitively resolved this by color flow Doppler. She remained clinically asymptomatic although notably required three admissions for upper respiratory infections during the previous year. She was scheduled for elective closure of the ASD and resection of the cor triatriatum membrane. An intraoperative transesophageal echocardiogram was performed, which demonstrated normal pulmonary venous return and concern for a large extracardiac mass compressing the left atrium. The operative repair was delayed and the patient was transferred under anesthesia to the MRI suite to obtain a cardiac MRI for further evaluation of the mass prior to same day resection.

CASES OF THE WEEK 2016

NUMBER 16-13: INFILTRATIVE MASS: CARDIAC MRI TO ASSESS FOR AUTOTRANSPLANTATION CANDIDACY

A 55 year old previously healthy woman was evaluated for progressive dyspnea on exertion with associated chest tightness. She denied fevers, chills, and night sweats. She underwent a 2D-Echocardiogram which showed a large pericardial effusion with thickening of the right atrial wall and a mass just below the posterior tricuspid leaflet. Left and right ventricular systolic function was normal. Pericardiocentesis yielded 850 mL of hemorrhagic fluid, analysis of which was nondiagnostic. A CT of the chest, abdomen, and pelvis demonstrated numerous lung nodules, ground glass lesions and diffuse mediastinal lymphadenopathy. In addition, the cardiac mass was visualized. To define the probable etiology of the mass, cardiac MRI was performed for more precise localization and tissue characterization.

NUMBER 16-12: Hypertrophic cardiomyopathy, apical aneurysm, and inducible ischemia

The case of a 85 year-old lady is presented who complain of atypical chest pain.  After a markedly abnormal ECG showing high voltage R waves and deep, inverted T waves on precordial leads, an echocardiographic study is performed, suggesting non-obstructive hypertrophic cardiomyopathy (HCM).

A CMR exam is requested to: 1) confirm the diagnosis; 2) precisely determine the extent of the process; 3) establish the presence or not of myocardial fibrosis;  and 4) to rule out myocardial ischemia.
 

NUMBER 16-11: magnetic resonance late gadolinium enhancement detects acute aortic intramural hematoma

History: An 81-year-old male patient presented with sudden and intense chest pain. On the emergency ward, a transthoracic echocardiogram was performed showing an enlarged and wall-thickened thoracic aorta. Computed tomography angiography confirmed the enlarged and wall-thickened thoracic aorta. In non-contrast images, a high-attenuation crescentic thickening of the aortic wall suggested an intramural hematoma or aortitis (Figure 1). 18F-FDG-PET suggested that there was no overt inflammation but findings were equivocal (Figure 1). The patient was stable without pericardial effusion, periaortic hematoma, or large aortic aneurysm; therefore, a cardiac magnetic resonance imaging study was performed in the next 12 hours to rule out aortitis (1).

NUMBER 16-10: Organization of intracardiac thrombus: insights from inside a giant left ventricular pseudoaneurysm

A 57-year-old homeless man presented to the emergency room after a syncopal episode. He reported a two-day history of shortness of breath and upper back pain. He was noted to be hypotensive with a blood pressure of 92/69 mmHg. An electrocardiogram showed ST-segment elevations in the inferolateral leads. Emergent coronary angiography revealed diffuse obstructive disease in the left anterior descending coronary artery, occlusion of the distal left circumflex coronary artery and complete total occlusion of the proximal right coronary artery. The left circumflex lesion was felt to be the culprit and it was treated with balloon angioplasty. Echocardiography revealed a left ventricular ejection fraction (LVEF) of 15-20% with a contained rupture and pseudoaneurysm involving the lateral wall. He was recommended coronary artery bypass graft surgery and repair of the left ventricular (LV) pseudoaneurysm, which he refused. He was discharged with medical treatment and presented with NYHA Class III heart failure symptoms 4 months later. He was agreeable to surgery at this time and for surgical planning, he underwent a cardiovascular magnetic resonance (CMR) study.

NUMBER 16-09: SUBARACHNOID HEMORRHAGE UNMASKS AORTIC COARCTATION IN A YOUNG MAN

History: A 20-year-old male with a history of hypertension presented to the emergency department because of a severe headache. On examination, the patient was confused and disoriented. His BP was 135/61 mmHg, temperature 35.6°C (97.9°F), pulse 78, and respiratory rate 24. Cardiovascular exam showed a regular heart rhythm, a grade III/VI diastolic murmur heard best in the third left intercostal space, strong pulse, no edema, warm skin, and capillary refill of < 3 seconds. No lower extremity blood pressures were obtained.

NUMBER 16-08: LARGE ANEURYSMAL CORONARY ARTERY FISTULA: A UTILITY OF CARDIAC MRI IN DIAGNOSIS 

History: A 64 year old female presented with a long history of vague dyspnea on exertion and intermittent palpitations. She had a history of mild exercise intolerance for the last 50 years with difficulty keeping up with her peers as early as high school. She had a normal physical exam with no murmur or gallop. A recent 24 hour Holter monitor was concerning for intermittent supraventricular tachycardia with possible atrial fibrillation. Her transthoracic echocardiogram showed left atrial dilation and concern for possible cor triatriatum with a membrane across the mid left atrium. A nuclear stress test was negative with no evidence of infarct or ischemia. She had a transesophageal echocardiogram that showed no evidence of cor triatriatum, severe left atrial dilation, dilated right coronary artery ostium, and continuous unidentified flow into the left atrium. A cardiac MRI and chest MRA was performed to evaluate the etiology of left atrial dilation in the setting of a dilated coronary artery.

 

number 16-07: UHL’S ANOMALY: YOU’LL RECOGNIZE IT WHEN YOU SEE IT
