Middle cerebral artery (MCA) aneurysms usually arise at the primary MCA bifurcation or trifurcation. Distal MCA aneurysms are rarely considered as sources of aneurysmal subarachnoid hemorrhage (SAH). It has been reported that ruptured distal MCA aneurysms are associated with head trauma, neoplastic emboli, arterial dissection, or bacterial infection. We experienced five cases of ruptured distal MCA aneurysms and evaluated their clinical characteristics. Retrospective analysis of aneurysmal SAH at Kobayashi Neurosurgical Neurological Hospital was performed from January, 2004 to December, 2014...

Sinus of Valsalva aneurysm accounts for only 1% of congenital cardiac anomalies. Sinus of Valsalva aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture. Three-dimensional transesophageal echocardiography (3DTEE) represents an adjunctive tool to demonstrate the ruptured sinus of Valsalva with better delineation. We present an adult patient with rupture of noncoronary sinus of Valsalva aneurysm into the right atrium (RA). 3DTEE accurately delineated the site of rupture into the RA and showed the exact size and shape of the defect, which helped in the successful transcatheter closure of the defect with a duct occluder device...

BACKGROUND: Ventricular septal defect is a lethal complication after an acute myocardial infarction which have become infrequent with the advent of reperfusion strategies however; they remain a major contributor to mortality. METHODS: We identified patients using the ICD-9CM procedure codes from the Nationwide Inpatient Sample between the years 2001 and 2013. A multivariate hierarchical logistic regression model was used to identify significant predictors of in-hospital mortality...

Myocardial infarction (MI) triggers a reparative response involving fibroblast proliferation and differentiation driving extracellular matrix modulation necessary to form a stabilizing scar. Recently, it was shown that a genetic variant of the base excision repair enzyme NEIL3 was associated with increased risk of MI in humans. Here, we report elevated myocardial NEIL3 expression in heart failure patients and marked myocardial upregulation of Neil3 after MI in mice, especially in a fibroblast-enriched cell fraction...

Blunt Cardiac Rupture (BCR) is a life threatening injury. Majority of patients do not reach the hospital and in those who reach the emergency department, timely diagnosis and treatment is a challenge. The case is about a patient with multiple blunt injuries who presented in shock. Cardiac tamponade was suspected on clinical grounds and on evidence of mediastinal widening on radiograph. In the absence of songography, the diagnosis was confirmed by subxiphoid pericardial window. Emergency thoracotomy revealed a right atrial appendage rupture which was surgically corrected...

We report a case of an idiopathic coronary artery rupture in a 41-year-old male patient who was admitted to the hospital with cardiac tamponade. On opening the chest via a median sternotomy and establishing cardiopulmonary bypass the hemopericardium's cause could be identified as a perforation of the right posterior descending coronary artery which was treated with a saphenous vein patch plasty. With idiopathic coronary artery rupture being a rare diagnosis, one should always consider it in a young patient presenting with cardiac tamponade...

Acute coronary syndromes (ACS) encompass unstable angina, non-ST segment elevation myocardial infarction, ST-segment elevation myocardial infarction and sudden cardiac death. They are commonly associated with the presence of vulnerable plaques in the coronary arteries and occur when a thrombus formed from a ruptured atheromatous plaque causes a prolonged occlusion of a coronary artery. The erosion of the vulnerable plaques results in the formation of luminal thrombi secondary to platelet activation and the release of thrombogenic elements within the atherosclerotic lesions...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of severe aortic stenosis in intermediate, high-risk, and inoperable patients. TAVR has multiple access routes, including transfemoral (TF), transapical (TA), direct aortic (DA), axillary, transcarotid, and transcaval. The most commonly applied algorithm is a TF-first approach, where only when patients are unsuitable for TF are alternatives such as TA considered. An infrequent - but dreaded - risk is left ventricular (LV) apical bleeding from tearing or rupture with the TA approach...

BACKGROUND: Disrupted atherosclerotic plaques in the left anterior descending coronary artery are discussed controversially as a potential pathophysiological mechanism in Takotsubo syndrome (TTS). Therefore, the aim of the present study was to assess plaque burden and morphology by using optical coherence tomography in patients with TTS. METHODS AND RESULTS: A total of 23 consecutive TTS patients were included in this single-center study and underwent optical coherence tomography imaging of the left main coronary artery and the left anterior descending coronary artery at acute presentation...

The purpose of this study is to investigate the effect of various degrees of percentage stenosis on hemodynamic parameters during the hyperemic flow condition. 3D patient-specific coronary artery models were generated based on the CT scan data using MIMICS-18. Numerical simulation was performed for normal and stenosed coronary artery models of 70, 80 and 90% AS (area stenosis). Pressure, velocity, wall shear stress and fractional flow reserve (FFR) were measured and compared with the normal coronary artery model during the cardiac cycle...

A ruptured sinus of Valsalva aneurysm (RSVA) is a rare cardiac anomaly. Traditionally, RSVAs were repaired surgically; however, percutaneous transcatheter closure is the current treatment of choice. We report two cases of RSVA which were closed using this approach. The first case was a 45-year-old female who presented to the Royal Hospital, Muscat, Oman, in 2014 with a RSVA in the right ventricle. The second case was a 39-year-old male who was admitted to the Sultan Qaboos University Hospital, Muscat, in 2015 with a large multifenestrated RSVA extending into the right ventricle outflow tract...

Acute ST segment elevation myocardial infarction (STEMI) is typically associated with acute coronary thrombosis or plaque rupture. Rarely, STEMI can be associated with ascending aortic dissection, which represents the majority of acute aortic syndrome aetiologies and carries dreadful outcomes. Routine cardiac intervention with emergent cardiac catheterisation may lead to a higher mortality rate in this group of patients. We present a case of painless inferior STEMI in the setting of ascending aortic dissection...

Delayed cardiac tamponade (DCT) is a rare and life-threatening complication of catheter ablation performed as a treatment of atrial fibrillation, with few cases described in the medical literature. We present the case of a 57year-old man presenting with DCT 61days following a catheter ablation procedure. To the best of our knowledge, this is the most delayed case of cardiac tamponade (CT) following catheter ablation described in the literature. We also discuss the importance of point of care ultrasound (POCUS) in the diagnosis and treatment of CT...

OBJECTIVE: Although endovascular repair of ruptured abdominal aortic aneurysms (rAAAs) is increasingly more prevalent and may yield better results, open repair of rAAAs is still commonly performed. Our goal was to assess the contemporary practice patterns and outcomes of open repair of rAAA. METHODS: The 2011-2014 American College of Surgeons National Surgical Quality Improvement Program targeted open AAA database was queried for all rAAAs. Patient characteristics, presentation, aneurysm details, and operative details were analyzed to identify factors that may affect outcome in this population of patients...

Infertility is a medical and psychosocial problem with a high prevalence. There are different treatments for this problem in Iranian traditional medicine. A 28-year-old woman presented with the complaints of 4 emergency operations of the left ovarian cyst during 4 years and infertility. Diagnostic laparoscopy showed an ovarian cyst, adhesion, and endometriosis. Hysteroscopy was unremarkable. After 2 months of letrozole administration, the ovarian cyst ruptured again. Considering the failure of conventional treatments, Iranian traditional medicine products were administered to the patient...

We report a rare case of cardiac failure for intrapericardial hematoma 11 years after coronary artery bypass grafting. A 59-year-old man was admitted to our hospital with cardiac tamponade. Echocardiography and computed tomography scan showed severe compression of the left ventricle(LV) by a large mass sized about 5×8 cm. Coronary angiography showed total occlusion at circumflex branch (Cx) #11. The mass was diagnosed with intrapericardial hematoma. We performed removal of hematoma in the pericardial cavity, and removed hematoma had 126 g...
