Multimodality Imaging in the Evaluation of Ascending Aortic Pseudoaneurysms to Guide Complex Surgical Management

ABSTRACT: Graphical abstract Highlights • Treatment of an AAP is surgical.• The CorMatrix patch can lead to degradation and pseudoaneurysm formation.• Use of multimodality imaging is key to evaluate, diagnose, and guide operation.

Percutaneous Closure of Iatrogenic Ascending Aortic Pseudoaneurysms Following Surgical Aortic Repair.

Project description:We present a case series of 4 iatrogenic ascending aortic pseudoaneurysms that were all successfully repaired with a percutaneous approach. Pre-procedural imaging, device selection, and procedural techniques are described. With careful preparation and patient selection, catheter closure of iatrogenic ascending aortic pseudoaneurysms can be performed reliably and safely. (Level of Difficulty: Advanced.).

Surgical management of a giant ascending aortic pseudoaneurysm.

Project description:Aortic pseudoaneurysm is a rare, life-threatening complication after cardiac or aortic root surgery. When a pseudoaneurysm has eroded bony structures in the chest, the surgeon's challenge is to choose the safest approach for sternotomy. Herein, we report the case of a 74-year-old woman who presented with a giant pseudoaneurysm of the ascending aorta, 8 years after undergoing aortic valve replacement. The 8.9×5.8-cm formation arose in the anterior aortic sinus, extended to the retrosternal region, exerted mass effect on the main pulmonary artery, and eroded the bony structures of the sternum and medial upper chest. A new aortic valved tissue conduit was placed, and the coronary arteries were reimplanted. The patient recovered without neurologic sequelae. We discuss the characteristics of this case and explain our surgical decisions.

Multimodality imaging of a giant aortic valve papillary fibroelastoma.

Project description:Papillary fibroelastomas (PFEs) are benign cardiac tumors arising from endocardium. They are commonly found on valvular surfaces and average 1.0-1.5 cm in size. Though often asymptomatic, PFEs can lead to potentially severe complications, primarily due to their embolic potential. Surgical resection is recommended for all symptomatic or large PFEs. We report the case of a patient presenting with cardiovascular symptoms who was found to have a very large aortic valve PFE, as diagnosed by histopathologic examination following surgical resection. Multimodality cardiovascular imaging demonstrates the classic morphologic findings, including a pedunculated appearance and oscillating "frond-like" surface projections.

Multimodality Imaging for the Assessment of Severe Aortic Stenosis.

Project description:Aortic stenosis is the most common type of valvular heart disease. Aortic stenosis is characterized both by progressive valve narrowing and the left ventricular remodeling response that ensues. In aortic stenosis, therapeutic decision essentially depends on symptomatic status, stenosis severity, and status of left ventricular systolic function. Imaging is fundamental for the initial diagnostic work-up, follow-up, and selection of the optimal timing and type of intervention. Noninvasive imaging has played a pivotal role in enhancing our understanding of the complex pathophysiology underlying aortic stenosis, as well as disease progression in both the valve and myocardium. The present review provides the application of multimodality imaging in aortic stenosis.

Multimodality Imaging in a Patient With Double Aortic Arch Undergoing Transcatheter Aortic Valve Implantation.

Project description:Double aortic arch is a rare congenital malformation often identified as an incidental finding during routine imaging. In our case, we describe aortic hemodynamics of double aortic arch in a patient with severe aortic stenosis and the procedural process of transcatheter aortic valve implantation.

A multimodality test to guide the management of patients with a pancreatic cyst.

Project description:Pancreatic cysts are common and often pose a management dilemma, because some cysts are precancerous, whereas others have little risk of developing into invasive cancers. We used supervised machine learning techniques to develop a comprehensive test, CompCyst, to guide the management of patients with pancreatic cysts. The test is based on selected clinical features, imaging characteristics, and cyst fluid genetic and biochemical markers. Using data from 436 patients with pancreatic cysts, we trained CompCyst to classify patients as those who required surgery, those who should be routinely monitored, and those who did not require further surveillance. We then tested CompCyst in an independent cohort of 426 patients, with histopathology used as the gold standard. We found that clinical management informed by the CompCyst test was more accurate than the management dictated by conventional clinical and imaging criteria alone. Application of the CompCyst test would have spared surgery in more than half of the patients who underwent unnecessary resection of their cysts. CompCyst therefore has the potential to reduce the patient morbidity and economic costs associated with current standard-of-care pancreatic cyst management practices.

Multimodality imaging in the surgical treatment of children with nonlesional epilepsy.

Project description:ObjectivesTo evaluate the diagnostic value of individual noninvasive presurgical modalities and to study their role in surgical management of nonlesional pediatric epilepsy patients.MethodsWe retrospectively studied 14 children (3-18 years) with nonlesional intractable focal epilepsy. Clinical characteristics, surgical outcome, localizing features on 3 presurgical diagnostic tests (subtraction peri-ictal SPECT coregistered to MRI [SISCOM], statistical parametric mapping [SPM] analysis of [18F] FDG-PET, magnetoencephalography [MEG]), and intracranial EEG (iEEG) were reviewed. The localization of each individual test was determined for lobar location by visual inspection. Concordance of localization between each test and iEEG was scored as follows: 2=lobar concordance; 1=hemispheric concordance; 0=discordance or nonlocalization. Total concordance score in each patient was measured by the summation of concordance scores for all 3 tests.ResultsSeven (50%) of 14 patients were seizure-free for at least 12 months after surgery. One (7%) had only rare seizures and 6 (43%) had persistent seizures. MEG (79%, 11/14) and SISCOM (79%, 11/14) showed greater lobar concordance with iEEG than SPM-PET (13%, 3/14) (p<0.05). SPM-PET provided hemispheric lateralization (71%, 10/14) more often than lobar localization. Total concordance score tended to be greater for seizure-free patients (4.7) than for non-seizure-free patients (3.9).ConclusionsOur data suggest that MEG and SISCOM are better tools for lobar localization than SPM analysis of FDG-PET in children with nonlesional epilepsy. A multimodality approach may improve surgical outcome as well as selection of surgical candidates in patients without MRI abnormalities.
