Cerebral aneurysms in complex anatomical locations and intraoperative rupture of aneurysms are challenging for neurosurgeons and anaesthetists alike. Mechanical and non-mechanical methods to reduce blood flow into aneurysms are well-recognised techniques to facilitate aneurysm exclusion from the circulation. Mechanical methods like temporary clipping of parent arteries, carotid artery ligation and endovascular balloon occlusion are commonly used in clinical practice. However, non-mechanical techniques such as rapid ventricular pacing and adenosine-induced cardiac standstill with hypotension are still emerging strategies...

A 69-year-old man was admitted to our hospital for dyspnea and fever. Echocardiography showed a mobile mass on the anterolateral papillary muscle and severe mitral regurgitation. Coronary artery angiography showed no stenotic lesion. Infective endocarditis or cardiac tumor was suspected, and a mitral valve operation was performed. Intraoperative observation revealed a partially ruptured anterolateral papillary muscle and no evidence of infection or tumor. Pathologic examination of the resected papillary muscle showed atherosclerotic changes in small arteries and infarcted areas in different postinfarct time phases along the ruptured edge...

A sinus of Valsalva aneurysm is a rare cardiac anomaly that may be congenital or acquired. Very rarely, they present with acute symptoms as a result of rupture into the cardiac chamber. If left untreated, they almost always result in deteriorating cardiac function. We report a patient presenting with acute right heart failure and hepatorenal syndrome requiring urgent surgery and double patch repair.

Transabdominal ultrasound elasticity imaging could improve the assessment of rupture risk for abdominal aortic aneurysms by providing information on the mechanical properties and stress or strain states of vessel walls. We implemented a non-rigid image registration method to visualize the pressure-normalized strain within vascular tissues and adapted it to measure total strain over an entire cardiac cycle. We validated the algorithm's performance with both simulated ultrasound images with known principal strains and anatomically accurate heterogeneous polyvinyl alcohol cryogel vessel phantoms...

Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination...

Cardiac tamponade is an important and potentially lethal complication of acute pericarditis. However, recurrence of cardiac tamponade is rare when it is treated appropriately. We present a 49-year-old man with bacterial pericarditis and recurrent cardiac tamponade, which was caused by the rupture of an upper part of the left atrium (LA). According to the autopsy findings, bacteremia from Staphylococcus aureus developed on a substrate of poorly controlled diabetes mellitus and spread to the pericardium via the blood...

BACKGROUND: Pulmonary artery aneurysms constitute <1% of aneurysms occurring in the thoracic cavity. Congenital cardiac defects are responsible for the majority (>50%) of cases, however, pulmonary artery aneurysm is a rare sequelae of pulmonary tuberculosis reported in about 5% of patients with chronic cavitary tuberculosis on autopsy. The natural history of this potentially fatal condition remains poorly understood and guidelines for optimal management are controversial. CASE PRESENTATION: A 24-year-old man, a nursing student of African descent, was referred to us from an up-country regional hospital with a 4-week history of recurrent episodes of breathlessness, awareness of heartbeats and coughing blood 3 weeks after completing a 6-month course of anti-tuberculosis drugs...

Background Thoracic aortic aneurysm rupture is often a fatal condition. Emergent thoracic endovascular aortic repair (TEVAR) has emerged as a suitable treatment option. Unfortunately, respiratory complications from hemothorax continue to be an important cause of morbidity and mortality even after successful management of the aortic rupture. We hypothesize that early hemothorax decompression after TEVAR for ruptured aneurysms decreases the rate of postoperative respiratory complications. Methods Single-center, retrospective eight-year review of ruptured thoracic aneurysms treated with TEVAR...

Blunt cardiac injury is a life-threatening condition. We report 3 successful cases in which we performed surgery for blunt cardiac injury. Three individuals were injured, 2 in traffic accidents and the other being caught between a crane and a steel frame. Echocardiograms and computed tomography scans revealed pooling of bloody pericardial fluid in all 3 patients, who underwent emergency surgery. Two patients needed sutures to control persistent bleeding. Although a heart-lung machine was prepared at the start of surgery in all 3 cases, we did not need to use it for any patient...

Acute coronary events, the dreaded manifestation of coronary atherosclerosis, remain one of the main contributors to mortality and disability in the developed world. The majority of those events are associated with atherosclerotic plaques-related thrombus formation following an acute disruption, that being rupture or erosion, of an event-prone lesion. These historically termed vulnerable plaques have been the target of numerous benchtop and clinical research endeavors, yet to date without solid results that would allow for early identification and potential treatment...

Heart development requires coordinated activity of various factors, the disturbance of which can lead to congenital heart defects. Heart lectin-associated matrix protein-1 (hLAMP-1) is a matrix protein expressed within Hensen's node at Hamburger-Hamilton (HH) stage 4, in the lateral mesoderm by HH stages 5-6 and enhanced within the left pre-cardiac field at HH stage 7. At HH stages 15-16, hLAMP-1 expression is observed in the atrioventricular canal and the outflow tract. Also, the role of hLAMP-1 in induction of mesenchyme formation in chick heart has been well documented...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is standard therapy for patients with severe aortic stenosis who are at high surgical risk. However, national data regarding procedural characteristics and clinical outcomes over time are limited. OBJECTIVES: The aim of this study was to assess nationwide performance trends and clinical outcomes of TAVR during a 6-year period. METHODS: TAVRs performed in 48 centers across France between January 2013 and December 2015 were prospectively included in the FRANCE TAVI (French Transcatheter Aortic Valve Implantation) registry...

Post-myocardial infarction ventricular septal defect corresponds to the rupture of the ventricular septum between the healthy and infarcted parts. It is a rare complication still associated with a high mortality rate. Its diagnostic should be evoked in case of pathologic cardiac auscultation and confirmed by emergent transthoracic echocardiography. Hemodynamic stabilisation, mainly with the insertion of an intra-aortic balloon pump is the first step in the management. The subsequent modality of closure, either surgical or transcatheter, as well as the ideal timing should be discussed in the Heart team...

BACKGROUND: Scar pregnancy is an extremely rare type of ectopic pregnancy, where there is implantation of the gestational sac onto the anterior wall of the uterus at the site of previous LSCS scar in a multipara female. Due to a poor vascular supply to the lower uterine segment, caesarean scars may heal improperly predisposing it to be a site of improper implantation of the gestational sac. RESULTS: The characteristic features are empty uterus and cervix, gestational sac in the anterior part of lower uterine segment with a history of painless vaginal bleeding...

BACKGROUND: Cardiac tamponade due to aortic injury after blunt trauma is a rare and potentially fatal injury. Most aortic injuries caused by blunt trauma present as aortic dissection or rupture of the aortic isthmus. Several cases of delayed aortic injury have been reported. However, all of these injuries were observed in the descending aorta because they had been caused by a posterior rib fracture. CASE PRESENTATION: We report the first case of cardiac tamponade associated with delayed ascending aortic perforation 2 weeks after blunt trauma...
