A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement...

INTRODUCTION: Ex vivo measurement of ascending aortic biomechanical properties may help understand the risk for rupture or dissection of dilated ascending aortas. A validated in vivo method that can predict aortic biomechanics does not exist. Speckle tracking transesophageal echocardiography (TEE) has been used to measure ventricular stiffness; we sought to determine whether speckle TEE could be adapted to estimate aortic stiffness in vivo and compare these findings with those obtained by ex vivo tissue measurements...

BACKGROUND: Stress induced hyperglycemia (SIH) after acute cerebrovascular disease is common and is associated with adverse clinical outcomes. Incidence of SIH after spontaneous subarachnoid hemorrhage (SAH) and its role in shunt placement has not been systematically investigated. Present study is designed to investigate the incidence of SIH after spontaneous SAH and its determinants. Role of SIH and premorbid hyperglycemia (using glycated hemoglobin, HbA1c) in predicting external ventricular drainage (EVD) and ventriculoperitoneal shunt (VPS) placement is also investigated...

OBJECTIVE The most frequent procedural complication of the endovascular treatment of intracranial aneurysms is a thromboembolic event (TEE); in a subset of patients, such events will cause permanent neurological disability. In patients with unruptured aneurysms, increasing evidence supports the use of periprocedural antiplatelet therapy to prevent TEEs. The object of this study was to evaluate whether patients with ruptured aneurysms and subarachnoid hemorrhage would also benefit from periprocedural antiplatelet therapy...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

AIM: To evaluate the effects of combined coronary artery bypass grafting (CABG), surgical left ventricular restoration (LVR), and mitral valve repair (MVP) in treating ischemic heart disease combined with mitral regurgitation; and to evaluate the different strategies of LVR and MVP. METHODS: From January 2001 to December 2015, 61 consecutive patients with left ventricular aneurysm and ischemic mitral regurgitation underwent concomitant CABG, LVR and MVP. We evaluated the clinical and echocardiographic outcomes of the patients...

BACKGROUND: Patients with aneurysmal subarachnoid hemorrhage (aSAH) are susceptible to various medical complications, including ventriculostomy-associated infections (VAIs) in those who undergo external ventricular drain (EVD) placement. Many VAI preventative strategies have been utilized over the last 20 years, but their overall effect is unknown. Using the Nationwide (National) Inpatient Sample (NIS), this study examines trends in VAI rates and mortality over a recent 12-year period in the aSAH population...

BACKGROUND: We retrospectively analyzed 65 patients who underwent surgical repair of sinus of Valsalva aneurysm over the last 27 years. METHODS: From January 1, 1988, to October 1, 2015, a total of 65 patients with sinus of Valsalva aneurysm underwent surgical repair in our hospital. There were 41 males (63%) and 24 females (37%), and their age ranged from 5 to 50 years (mean 23 ± 10 years, median 21 years). Out of the 65 patients, 45 (69%) had ruptured sinus of Valsalva aneurysm, 46 (70%) had a ventricular septal defect, and 22 (34%) had aortic valve insufficiency...

Dynamic systolic compression of the coronary arteries is almost always due to the existence of myocardial bridging that is most commonly localized in the middle segment of the left anterior descending coronary artery. However, it has rarely been reported in patients with pericardial adhesions, tumor, foreign body, or pseudoaneurysms. Only rare case reports exist regarding dynamic coronary compression by a dyskinetic left ventricular aneurysm. We present a patient with a myocardial bridge-like systolic compression of the distal left anterior descending caused by postinfarction dyskinetic left ventricular aneurysm...

Giant coronary artery aneurysms are rare clinical entities. We report the case of a 49-year-old man who presented with dyspnoea and exertional chest pain. Investigations confirmed an aneurysmal right coronary artery measuring 4 cm with a fistulous communication to the right atrium. Following right atriotomy, the fistula was oversewn and the aneurysmal right coronary artery ligated at its origin and at several points along its course. A saphenous vein graft was anastomosed to the posterior descending artery...

BACKGROUND AND OBJECTIVES: The aneurysm in the pulmonary trunk is a rare disease. Because of its location, a rupture can lead to right ventricular failure and sudden death. Aneurysmorraphy is the most widely used surgical treatment in these cases. The aim of this study is to report a successful balanced general anesthesia for aneurysmorraphy of pulmonary trunk. CASE REPORT: Male patient, 28 years, asymptomatic, diagnosed with an aneurysm in the pulmonary trunk. According to the location of the aneurysm and the consequent failure of the pulmonary valve, an aneurysmorraphy was indicated, with implantation of vascular-valvular prosthesis (valved tube)...

Sustained ventricular tachycardia complicating left ventricular apical aneurysms has been reported previously solely in middle-aged patients with hypertrophic cardiomyopathy and mid-cavity obstruction. We report a case of an elderly female patient who presented with incessant ventricular tachycardia as the first clinical manifestation of hypertrophic cardiomyopathy with mid-ventricular obstruction and apical aneurysm.

BACKGROUND: Delayed cerebral ischemia (DCI) contributes to morbidity following aneurysmal subarachnoid hemorrhage; however, its etiology remains poorly understood. DCI is not only a consequence of angiographic vasospasm, but also involves microthrombosis and neuroinflammation, two events with unexplained phenomenology. The vascular endothelial glycocalyx mediates platelet aggregation and endothelial cell-leukocyte interactions and may play an important role in DCI pathogenesis. METHODS: We present a case series in which we conducted multiplex and singlet enzyme-linked immunosorbent assays of endothelial, glycocalyx, inflammatory, and neuroinjury proteins in both CSF and plasma in three patients during active DCI following SAH...

BACKGROUND: Patients with aneurysmal subarachnoid hemorrhage (SAH) often develop hydrocephalus requiring an external ventricular drain (EVD). The best available evidence suggests that a rapid EVD wean and intermittent CSF drainage is safe, reduces complications, and shortens ICU and hospital length of stay as compared to a gradual wean and continuous drainage. However, optimal EVD management remains controversial and the baseline practice among neurological ICUs is unclear. Therefore, we sought to determine current institutional practices of EVD management for patients with aneurysmal SAH...

BACKGROUND: Currently, a complete understanding of post-ventriculostomy hemorrhagic complications in subarachnoid hemorrhage due to ruptured aneurysms remains unknown. The present study evaluates the impact of periprocedural risk factors on rates of external ventricular drain (EVD)-associated hemorrhage in the setting of endovascular treatment of intracranial aneurysms. METHODS: A retrospective chart review of 107 patients who underwent EVD placement within 24 h of endovascular coiling was performed...
