BACKGROUND: Consumption of n-3 fatty acids reduces the incidence of cardiovascular mortality in populations that consume diets rich in fish oil. Eicosapentaenoic acid (EPA) is an n-3 fatty acid known to reduce the frequency of nonfatal coronary events; however, the frequency of mortality after myocardial infarction (MI) is not reduced. The aims of this study were to determine whether long-term administration of EPA regulated cardiac remodeling after MI and to elucidate the underlying therapeutic mechanisms of EPA...

Left ventricular pseudoaneurysms have become a rare complication of acute myocardial infarction, occurring in approximately 2% of cases and even less frequently when primary percutaneous intervention can be performed. Regardless of treatment strategy, left ventricle pseudoaneurysms are associated with a high mortality rate. We report on the extremely rare occurrence of a patient surviving two episodes of free wall rupture associated with extensive chest wall destruction and secondary traumatic rib fractures...

The main goal of this study is to investigate a combination of viscosity-sensitive and viscosity-insensitive fluorescent dyes to distinguish different rheological states of hydrogel based biostructural materials and carriers in biological tissues and to assess their corresponding location areas. The research is done in the example of alginate hydrogel stained with viscosity-sensitive dyes Seta-470 and Seta-560 as well as the viscosity-insensitive dye Seta-650. These dyes absorb/emit at 469/518, 565/591 and 651/670 nm, respectively...

The management of pulmonary atresia with a ventricular septal defect (PA/VSD) depends on the anatomy of the pulmonary artery or on the surgical strategy used at individual institutions. In our institution, we adopted a right ventricle-to-pulmonary artery (RV-PA) shunt in 2011 as a palliative procedure for PA/VSD to overcome the disadvantages of a Blalock-Taussig shunt. We evaluated the results of the RV-PA shunt as initial palliative surgery for PA/VSD. Thirteen patients with ductus-dependent PA/VSD from August 2011 to August 2015 were enrolled...

OBJECTIVE: Ventricular septal rupture (VSR) is a severe complication of acute myocardial infarction, and the conventional technique for repair is associated with high operative mortality. A novel intraventricular stent graft (IVSG) device was tested as a less invasive treatment for VSR; it does not require cardiopulmonary bypass, cardiac arrest, or left ventricular incision. Its effectiveness was assessed using animal experiments. METHODS: Six pigs were placed on cardiopulmonary bypass...

Left ventricular pseudoaneurysm (LVPsA) is a rare complication after sutureless patch repair of left ventricular free wall rupture (LVFWR), with few cases reported in the literature so far. We present the case of a young patient who early developed a huge LVPsA and moderate mitral regurgitation after sutureless patch repair for LVFWR after undergoing a successful Dor procedure using the "triple empanada patch technique" to exclude the LVPsA, remodel the left ventricle, and address the moderate mitral regurgitation...

Cardiac rupture (CR) is one of the most serious and life-threatening complications of blunt chest trauma (BCT) usually associated with high mortality. Moreover, its diagnosis and treatment strategies may be extremely challenging for clinicians due to various anatomical localisations of the tear. Whereas most injuries fall under the category of right atrial ruptures, left ventricular lesions represent a rare type of this injury, with greater mortality, particularly in cases of multi-chamber injuries. However, not only cardiac chamber or great vessel ruptures may occur as a result of BCT; a growing number of reports also describe BCT-induced isolated coronary artery injuries, including ruptures...

Heart failure is one of the most important issues that has been investigated in recent research studies. Variations that occur in apparatus of mitral valve, such as chordae tendineaea rupture, can affect the valve function during ventricular contraction and lead to regurgitation from the left ventricle into the left atrium. One method for understanding mitral valve function in such conditions is computational analysis. In this paper, we develop a finite element model of mitral valve prolapse, considering the direct effect of left ventricular motion on blood flow interacting with the mitral valve...

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...

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...

Postinfarction ventricular septal rupture is a life-threatening complication of acute myocardial infarction. Although some novel techniques of ventricular septal rupture closure have been introduced, they involve ventriculotomy, a procedure that can cause a degree of impairment of the incised ventricle. We describe a case in which we closed a ventricular septal rupture through the tricuspid valve, without ventriculotomy.

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...

Sinus of Valsalva (SoV) aneurysm is a rare cardiac disease which can be congenital or acquired. A ruptured SoV aneurysm presents a clinical emergency and can lead to progressively deteriorating heart failure. Therefore, appropriate treatment requires prompt and accurate diagnosis. Most ruptured or nonruptured SoV aneurysms are diagnosed by the means of echocardiography. However, cardiovascular magnetic resonance (CMR) can provide information on precise anatomy and mechanisms due to its excellent soft tissue contrast and high resolution, and thereby allows for optimized preoperative planning of the repair strategy...

The aorta can rupture at the aortic root or aortic arch. In most breeds, the aortic root is the likely site and rupture leads to aortocardiac fistula with communication between the aorta and the right atrium, right ventricle and/or the interventricular septum. There is a high prevalence of aortic rupture in young Friesian horses and rupture occurs at the aortic arch with pseudoaneurysm and potentially aortopulmonary fistulation. Echocardiographic and post-mortem techniques must be adapted to identify aortic arch rupture that is not generally identified with standard approaches...

Bicuspid aortic valve (BAV) is a common congenital cardiac anomaly, and rarely, it is associated with sinus of Valsalva aneurysms (SOVAs). And very infrequently, these SOVAs rupture into left side of heart. We hereby report a case of 12-year-old male with BAV with severe aortic stenosis with a large SOVA that ruptured into the left side of the heart. The anatomy was delineated with multimodality imaging; initially with two-dimensional trans-thoracic echocardiography (TTE), and later on with three-dimensional TTE and with multi detector computed tomography...

Dermoid cysts are rare, benign lesions of embryological origin that represent 0.1-0.7% of all intracranial tumors. They are mainly located in the supra tentorial space, especially in the parasellar region. Their location in the posterior fossa remains uncommon. Rupture of intracranial dermoid cysts is a rare phenomenon. We present a case of dermoid cyst, which had ruptured into ventricular system. Computed Tomography and MRI revealed fat in the fourth ventricle, prepontine cistern, and cerebellomedullary cistern...

A thoracic aortic pseudoaneurysm is a life-threatening complication following thoracic aortic surgery. We describe a surgical strategy for this pseudoaneurysm with a high risk for rupture during median sternotomy. The pseudoaneurysm was distended and widely adherent to the posterior sternum. Elective cardiopulmonary bypass and moderate hypothermia were established, and sternotomy was performed without left ventricle distention or brain ischemia. Total arch replacement was successful and the patient was discharged on post operative day (POD) 18...

Autopsy imaging (Ai), postmortem imaging before necropsy, is used in human forensic medicine. Ai was performed using computed tomography (CT) for a 1-month-old Thoroughbred foal cadaver found in a pasture. CT revealed pericardial effusion, collapse of the aorta, bleeding in the lung lobe, gas in the ventricles and liver parenchyma, and distension of the digestive tract. Rupture in the left auricle was confirmed by necropsy; however, it was not depicted on CT. Therefore, Ai and conventional necropsy are considered to complement each other...
