BACKGROUND: Blake's pouch cyst forms from non-permeabilization of Blake's pouch. It is difficult to visualize at necropsy as the cyst ruptures easily into the 4th ventricle during dissection. CASE REPORT: Based upon prenatal imaging, delicate dissection allowed post-mortem confirmation of the Blake's pouch cyst. CONCLUSIONS: This highlights the importance of utilizing premortem imaging to help guide the postmortem dissection and documentation of a posterior fossa cyst...

BACKGROUND: The CT finding of "vulnerable plaque" is widely regarded as similar to that of a culprit lesion in an acute coronary syndrome (ACS). However, this hypothesis may not be accurate, since "vulnerable plaques" may substantially change their morphology when they rupture to cause an ACS. METHODS: We retrospectively evaluated coronary CT angiography data sets of 25 patients with ACS who had vulnerable (n = 10) or culprit plaques (n = 15). We analyzed CT features including positive remodeling (PR), low attenuation plaque (LAP), the napkin ring sign (NRS), degree of stenosis (normal, <50%, 50-99%, 100%), and myocardial hypoperfusion in the left ventricle...

OBJECTIVE: Blood blister-like aneurysms (BBAs) in the dorsal segment of the internal carotid artery (ICA) are fragile and difficult to treat, and the optimal treatment for BBAs is still controversial. We report clinical and angiographic results with procedural details for the treatment of BBA by using the endovascular patch embolization method. METHODS: We retrospectively reviewed patients who presented with subarachnoid hemorrhage(SAH) caused by ICA-BBAs and were treated with the endovascular patch embolization method in our center from October 2011 to March 2015...

Coronary artery fistula (CAF) is an uncommon anomaly that is usually congenital but can be acquired. Although most patients are asymptomatic, some may present with congestive heart failure, infective endocarditis, myocardial ischemia or rupture. In the past, surgical ligation was the only option in the management of CAF, but since 1983, transcatheter closure of CAF has been increasing as an alternative to surgery. We report a 3-year-old boy, presented in Queen Alia Heart Institute, who underwent successful transcatheter closure of a large fistula communicating the distal part of the right coronary artery to the right ventricle...

OBJECTIVE: The transciliary keyhole approach has been actively employed for unruptured intracranial aneurysms in many institutions, although applying this technique to ruptured aneurysms remains controversial. We investigated the risk factors related to poor surgical outcomes in ruptured aneurysm and attempted to clarify the differences between conventional craniotomy and keyhole surgery. METHODS: A total of 188 patients who underwent keyhole surgery due to ruptured anterior circulation aneurysms were enrolled at a single institution...

BACKGROUND: Guidelines allow percutaneous pulmonary valve implantation (PPVI) in conduits above 16mm diameter. Balloon dilatation of a conduit to a diameter>110% of the original implant size is also not recommended. We analyzed patients undergoing PPVI in such conditions. METHODS AND RESULTS: Nine patients (May 2008-July 2016) from 8 institutions underwent PPVI in conduits <16mm diameter. Five patients with 16-18mm conduit diameter underwent PPVI after over-expansion of the conduit>110%...

Hamartoma of mature cardiac myocytes (HMCM) is a rare benign pseudoneoplastic myocardial lesion. We describe a case of 39-year-old Bulgarian woman living in the Czech Republic, who died because of rupture of anterior communicating artery aneurysm, and severe bronchopneumonia. An incidental finding at the autopsy was a whitish unencapsulated and not sharply demarcated tumor of the left ventricle and adjacent area of interventricular septum, which protruded above the plane of section. Microscopically the tumor consisted of various different forms of disorganized hypertrophic mature cardiac myocytes without vacuolization of cytoplasm, focally in a "herringbone" pattern...

Coronary artery perforation (CAP) is a rare, but potentially mortal possible complication of percutaneous coronary intervention. There are several treatment options for this complication, including prolonged balloon dilatation, use of a coronary stent graft, and bypass surgery. In this case report, a 65-year-old female patient who was admitted to the catheter laboratory with a diagnosis of acute coronary syndrome, was presented. Coronary angiography revealed total occlusion in the mid segment of the right coronary artery and a drug-eluting stent was implanted under 12 atm of pressure following pre-dilatation with a perfusion balloon...

Totally endoscopic robotic surgery is a safe approach to atrial septal defect closure in adults. Robotic approach can be an alternative to traditional incisions in the management of concomitant tricuspid valve regurgitation with ruptured chordae tendineae. Herein, we describe a woman who presented with atrial septal defect and tricuspid insufficiency after an unsuccessful percutaneous intervention with device removal from the right ventricle. Concomitant closure of septal defect and tricuspid valve repair with artificial chords was successfully performed using robot assistance...

Sinus of Valsalva aneurysms are extremely rare, and usually of a congenital nature. There are few documented cases of this condition during pregnancy, which renders unclear the therapeutic options. We here report the case of a 26 years old pregnant woman who was referred to our cardiac center for the evaluation of a heart murmur. The two-dimensional transthoracic echocardiography allowed quickly to establishthe diagnosis of a ruptured sinus of Valsalva aneurysm into the right ventricle. A successful surgical correction of the ruptured aneurysm was performed with patch repair...

OBJECT: Aneurysmal subarachnoid hemorrhage(SAH)associated with intracerebral hematoma(ICH)typically has a poor outcome. SAH with ICH tends to have a worse prognosis than SAH alone. The aim of the present study was to evaluate whether coil embolization during endovascular surgery with ventricle drainage and without ICH evacuation is an appropriate treatment. METHODS: A retrospective review was conducted between March 2012 and May 2015. Thirteen patients with SAH with ICH who underwent coil embolization were retrospectively analyzed...

Heart failure (HF) secondary to myocardial infarction (MI) is linked to kidney complications that comprise cellular, structural, functional, and survival indicators. However, the HF research is focused on left ventricle (LV) pathology. Here, we determined the comprehensive functional analysis of LV using echocardiography in transition from acute HF (AHF) to progressive CHF pathology and develop a histological compendium of the cardiosplenic and cardiorenal networks in pathological remodeling. In surgically-induced MI using permanent coronary ligation, the LV dysfunction is pronounced, with myocardium necrosis, wall-thinning and 20-30% LV rupture events that indicated AHF and CHF pathological remodeling in C57BL/6 male mice (2-4 months old; n=50)...

Echinococcosis in humans occurs as a result of infection by the larval stages of taenid cestodes of the genus Echinococcus. Most of the intracranial hydatids develop in brain parenchyma. Hydatid cyst within the cerebral ventricle is quite unusual. Literature review showed few case reports of childhood as well as adult intraventricular hydatid cysts. None of these cases presented for the first time with features of ruptured intraventricular cyst. This is a very rare presentation of a common disease. The possibility of infestation with E...

BACKGROUND: Collateral artery aneurysms are a source of intracranial hemorrhage in moyamoya disease. Several reports have shown that surgical revascularization leads to the obliteration of collateral artery aneurysms. However, its effect on the prevention of rebleeding has not been established, and the optimal timing of the operation remains unclear. The purpose of the present study is to evaluate the effects of surgical revascularization and to investigate the optimal operation timing in patients with moyamoya disease who have ruptured collateral artery aneurysms on the ventricular wall...

A 54-year-old male developed a left ventricular pseudoaneurysm (Ps) along the lateral wall of the left ventricle (LV), which was diagnosed incidentally by two-dimensional transthoracic echocardiography (2DTTE) 6 months after an acute myocardial infarction. Color flow imaging (CFI) showed blood flow from the LV into the aneurysmal cavity and invasive coronary angiography revealed sub-occlusion of the circumflex artery. A complementary study using cardiovascular magnetic resonance (CMR) confirmed a dilated left ventricle with depressed ejection fraction, thin dyskinetic anterolateral and inferolateral walls, a Ps adjacent to the lateral wall of the LV contained by the pericardium and blood passing in and out through a small defect in the LV mid-anterolateral wall...

Although many clinical trials have demonstrated its efficacy during active compression-decompression cardiopulmonary resuscitation (ACD-CPR), the Ambu® CardioPump seems likely to cause severe and sometimes lethal injuries. In this paper, we report two cases observed at the Institute of Legal Medicine of Nancy, France. A 67-year-old man collapsed in the street, in the presence of witnesses, and without any sign of trauma. The autopsy revealed a flail chest, a wound of the left ventricle, a rupture of the right ventricle, and a wrenching of the inferior vena cava...

Craniopharyngioma is a relatively benign intracranial tumour that involves sellar and supra-sellar regions. Spontaneous rupture of craniopharyngioma into the sub-arachnoid space or into the ventricles is a rare phenomenon and few cases are reported in literature. We hereby report a case of sellar-suprasellar craniopharyngioma with focal intra-parenchymal rupture into brain causing aggravation of headache in a 12-year-old female child. This complication is a relatively rare phenomenon, which requires attention for early intervention...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom-made scalloped/fenestrated stent grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...
