Aortic regurgitation (AR) is characterized by the backflow of blood from the aorta to the left ventricle. Acute AR typically causes severe pulmonary edema and hypotension, and is a surgical emergency. In chronic AR, however, compensatory mechanisms can clinically compensate for years, with normal left ventricular function and no symptoms. While the hemodynamic mechanisms of chronic AR on the left ventricle are well described, the hemodynamic mechanisms of acute AR are not clear. Most of the literature on acute AR includes either small series or case reports...

BACKGROUND: Obesity contributes to left ventricular diastolic dysfunction (LVDD) and may lead to diastolic heart failure. Weight loss (WL) after bariatric surgery (BS) may influence LV morphology and function. Using echocardiography, this study assessed the effect of WL on LV diastolic function (LVDF) and LV and left atrium (LA) morphology 6 months after BS in young women with morbid obesity. METHODS: Echocardiography was performed in 60 women with BMI ≥ 40kg/m², aged 37...

RATIONALE: Death following orthopedic surgery has become rare, but does occur. Acute myocardial infarction (AMI) can be a cause of such death, but diagnosis of AMI is often challenging, even by autopsy. PATIENT CONCERNS: We have recently experienced 2 cases of sudden death after bone fracture surgery, in which AMI and pulmonary thromboembolism were clinically suspected as causes of death. Case 1 was a 60-year-old male with a history of diabetes mellitus who died 7 days after surgery for Lisfranc dislocation fracture...

Anomalous origin of the right coronary artery originating from the pulmonary trunk (ARCAPA) is a rare congenital coronary anomaly with an estimated prevalence of 0.002%. Most patients are asymptomatic and the anomaly is detected incidentally during evaluation for other problems. Occasionally, ARCAPA may lead to myocardial ischemia and/or sudden cardiac arrest. We present a case of a 55-year-old female with a history of hypertension who presented to the emergency department with intermittent chest discomfort for three days...

Coronary artery fistula (CAF) is a rare anomaly of the coronary artery. The draining site of a right coronary artery (RCA) fistula may usually be the right ventricle, right atrium, or pulmonary artery. Here, we present a patient with right coronary artery to coronary sinus fistula (RCACSF) complicated by aneurysmal dilatation of the coronary sinus (CS) and stenosis of CS ostium.

Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients with an anomalous left main coronary artery arising from the right sinus of Valsalva are presented. The diagnosis was made by coronary angiography, transesophageal echocardiography and multislice computed tomography (MSCT)...

BACKGROUND: Opinions regarding the optimal time for the repair of tetralogy of Fallot vary. A debate also exists about the timing of repair for the asymptomatic infant. METHODS: This study included 183 patients with tetralogy of Fallot. All patients were subjected to clinical examination with measurement of oxygen saturation, 12-lead ECG, plain chest x-ray, and complete laboratory investigation. Echocardiography and cardiac catheterisation were indicated if there was an inability to reach diagnosis by echocardiography, suspicion of coronary anomaly, evaluation of distal pulmonary arteries or suspicion of major aorto-pulmonary collaterals...

We present two cases of percutaneous Sapien XT valve-in-valve implantation in the tricuspid position: a 20-year-old man with severe congenital pulmonary stenosis and percutaneous valvuloplasty, who required surgical implantation of two protheses, pulmonary and tricuspid, and a 12-year-old boy with CHD and a degenerated tricuspid prosthesis. We implanted three Sapien XT valve-in-valves, two in the tricuspid position and one in the pulmonic position. Sapien XT valve-in-valve implantation in the tricuspid position is feasible and can decrease the number of surgeries in CHD patients...

An 85-year-old woman was brought to an accident and emergency department with breathing difficulties accompanied by inspiratory stridor. She was being treated for hypertension and severe osteoporosis which had caused thoracal and cervical fractures of the columna. Intubation was initiated as she desaturated and deteriorated despite maximum oxygen therapy. The intubation revealed a subglottic stenosis as a consequence of a recent osteoporotic fracture in the cervical columna. This represents a rare cause of respiratory failure as all other cardial, pulmonary and allergic aetiologies had been eliminated...

BACKGROUND: The predominant forms of adult large vessel vasculitis (LVV) are giant cell arteritis (GCA) and Takayasu arteritis (TA). Cardiac involvement in LVV is a cause of morbidity and mortality, particularly in TA. Cardiac failure is most commonly secondary to uncontrolled arterial hypertension or myocardial ischaemia. Pulmonary hypertension and aortic valve incompetence following ascending aortic dilatation represent other serious cardiovascular complications. However, cardiac failure as a consequence of myocarditis is rarely reported, principally in single case reports or in autopsy studies...

We describe a case involving a successful Fontan procedure for the treatment of pulmonary arteriovenous fistulas in a patient with polysplenia. The patient was diagnosed with bilateral superior vena cavae, interrupted inferior vena cava with azygos connection, wide separate hepatic veins, and central pulmonary artery stenosis following repair of a non-confluent pulmonary artery. Bilateral extracardiac conduits were used to connect each hepatic vein to the pulmonary artery, opposite each superior vena cava. Clinical improvement in the pulmonary arteriovenous fistulas was observed within 4 months after surgery...

Pulmonary vein (PV) stenosis is a known complication of PV isolation procedures for atrial fibrillation. We describe in this report a case of emergency covered stent implantation for rupture of a PV after balloon angioplasty for postinterventional PV stenosis occlusion. Focus is on stent implantation and on a novel aspect of magnetic resonance imaging for postprocedural outcome evaluation. A focused review of the current literature regarding ongoing limitations of PV stenosis treatment is provided.

Anomalous aortic origin of coronary arteries is rare. We report 3 cases of surgical treatment for anomalous aortic origin of coronary arteries. Case 1 was a 38-year-old man who was saved by the use of an automated external defibrillator from cardiopulmonary arrest while exercising. The coronary angiogram showed the right coronary artery arising from the left coronary sinus of Valsalva and being located between the aorta and the pulmonary trunk. He underwent coronary artery bypass grafting (CABG) using the right internal thoracic artery with ligation of proximal part of right coronary artery to prevent sudden death...

INTRODUCTION: Asthma is the most common chronic lower respiratory disease in childhood throughout the world. Recurrent respiratory tract infections in young children, especially viral infections, are the major cause of acute asthmatic exacerbations and contribute to development of asthma. Bacterial extracts have been used to improve the immune defenses of the respiratory tract. However, seldom studies have examined the effect of bacterial lysates on childhood asthma. In this study, we examined whether bacterial lysates (OM-85) will improve symptoms of asthmatic mice via modulation of the immune response...
