BACKGROUND: Standard cine-cardiac magnetic resonance (CMR) imaging is commonly used to evaluate cardiac structure, geometry and function. Prior studies have shown that automated segmentation via partial voxel interpolation (PVI) accurately quantifies phantom-based cardiac chamber volumes and necropsy left ventricular myocardial mass. Despite this, the applicability and usefulness of PVI in the determination of physiologic parameters of the aorta such as aortic stiffness has yet to be investigated...

Endocardial mapping of the left ventricle (LV) using the NOGA® XP Cardiac Navigation System can identify chronically ischemic and viable myocardium in patients with coronary artery disease by generating electromechanical maps. These maps are very useful when targeting myocardial tissue for injection of stem cells. We present the case of a woman who developed a perforation at the site of an LV aneurysm during NOGA mapping prior to the transendocardial injection of stem cells, as part of a multicenter clinical trial...

We report three cases of coronary fistula aneurysm associated with mitral valve insufficiency. The patients were referred to our cardiovascular department because of exertional dyspnea. Echocardiography showed severe mitral valve insufficiency resulting from leaflet flail or prolapse and normal left ventricular function. In all three cases, preoperative coronary angiography showed coronary-to-pulmonary artery fistula associated with significant aneurysm of the fistulous tract. All patients underwent uneventful mitral valve repair and external ligation of the fistulas...

We report a 63-year-old female with hypertension, hyperlipidemia, and prior pacemaker insertion for atrial fibrillation with symptomatic bradycardia, who was admitted with substernal chest pressure and diaphoresis. Her electrocardiogram revealed atrial fibrillation with demand ventricular pacing and her cardiac biomarkers were negative for acute coronary syndrome. Echocardiogram revealed normal left ventricular systolic function and normal aortic root diameter. Coronary angiography revealed 60-70% obtuse marginal lesion, otherwise mild disease...

Left ventricular aneurysm (LVA) is rare but potentially fatal complication of myocardial infarction. It has been strictly defined as a distinct area of abnormal left ventricular diastolic contour with systolic dyskinesia or paradoxical bulging. It may be asymptomatic. However, complications including thromboembolism, heart failure, valvular regurgitation, arrhythmia, and rarely rupture may be the initial presentation. Diagnosis may be established by transthoracic echocardiography, left ventriculography, computed tomographic angiography, and cardiac magnetic resonance imaging...

We previously reported the clinical usefulness of the mitral annular plane systolic excursion (MAPSE) to evaluate the left ventricular (LV) function in patients with Kawasaki disease (KD) in the acute-phase. However, the feasibility of the MAPSE z-score has not been evaluated in patients with acute KD. We prospectively studied 60 KD patients without coronary aneurysms. The MAPSE z-scores were calculated using our standard MAPSE data. Brain natriuretic peptide (BNP) was measured as a parameter of LV function...

BACKGROUND Electrocardiographic presentations of left ventricle aneurysms are diverse; however, a persistent ST segment elevation post myocardial infarction is most commonly reported. CASE REPORT The authors present a case of a 67-year-old man who presented to the emergency department after three days of chest pain and was found to have an acute myocardial infarction with an incidental finding of a left ventricular aneurysm. His surface electrocardiogram, however, demonstrated only inverted T waves in the precordial leads...

BACKGROUND: The Florida sleeve (FS) procedure was developed as a simplified approach for repair of functional type I aortic insufficiency secondary to aortic root aneurysm. We evaluated postoperative aortic valve function, long-term survival, and freedom from reoperation in Marfan syndrome patients who underwent the FS procedure at our center. METHODS: All Marfan syndrome patients undergoing FS procedure from May 2002 to December 2014 were included. Echocardiography assessment included left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), ejection fraction, and degree of aortic insufficiency (none = 0, minimal = 1, mild = 2, moderate = 3, severe = 4)...

REVIEW
Irtiza N Sheikh, William C Roberts
This minireview describes 6 previously reported patients with left ventricular free wall rupture and/or aneurysm complicating acute myocardial infarction (AMI) in patients with aortic stenosis. The findings suggest that left ventricular rupture and/or aneurysm is more frequent in patients with AMI associated with aortic stenosis than in patients with AMI unassociated with aortic stenosis, presumably because of retained elevation of the left ventricular peak systolic pressure after the appearance of the AMI.

The medical records of 2283 patients with ventricular septal defect (VSD) were reviewed to determine spontaneous closure, left ventricular-to-right atrial shunt, subaortic ridge, and aortic valve prolapse. One thousand eight hundred and twenty-three patients had been followed 1 month to 26 years (median 4 years) by echocardiography. Most of 460 patients could not be followed due to transportation of the institution. VSD was perimembranous in 68.8% (1255), trabecular muscular in 21.7% (395), muscular outlet in 6% (109), muscular inlet in 2...

Kathy Edelman, Angel López-Candales
A case of a patient presenting with an acute myocardial infarction is presented. A transthoracic echocardiographic examination revealed an abnormal color flow signal that traversed the myocardial wall from a large inferior aneurysm and initially considered to be a ventricular septal defect. However, further echocardiographic manipulation utilizing modified views along with sequential injections of both agitated saline and Definity(®) proved very useful to identify a pseudoaneurysm. There was no further need for any other diagnostic test, and the patient was treated surgically, undergoing successful repair of the pseudoaneurysm as well as coronary artery bypass grafting of the left coronary artery...

Speckle-tracking echocardiography is a recently developed technique for the evaluation of myocardial deformation or strain. Our objective was to examine strain through a mid-term follow-up of patients with Kawasaki disease. METHODS: We explored left ventricular mechanics using speckle-tracking echocardiography in 35 patients with a history of Kawasaki disease at least 6 months after the acute phase. We also included 30 healthy children as controls. Strain data sets were acquired for the quantification of left ventricular global strain, segmental strain, and left ventricular ejection fraction...

Subclavian artery aneurysm is usually operated under general anesthesia (GA), but in specific situations, it can also be conducted under regional anesthesia (RA) such as cervical epidural anesthesia (CEA). A 48-year-old male presented with chief complaint of progressive swelling in the right side of the neck for the past 3 months following trauma. He was diagnosed as subclavian artery aneurysm, and surgical intervention was advised. He had previous history of angina 4 months back for which tablet aspirin 75 mg and tablet clopidogrel 75 mg once daily was prescribed...
