The vertebral heart size (VHS) method by Buchanan is based on anatomic landmarks. A potential source of variation among observers is differences in the selection of measurement points. The objective was to test variability between observers with different levels of training in thoracic radiology and small animal clinical practice. Fifty sets of thoracic radiographs of cavalier King Charles span...

mitral valve replacement (mvr) is usually performed in two methods of running and interrupted suturing. in running method, the suturing of the valve is usually with some traction on the annulus and also there is a risk of aortic valve injury. this study was conducted to evaluate a new technique for suturing to avoid these complications and decrease the time of cardiac arrest. one hundred and se...

global myocardial ischemia and ischemia-reperfusion injury are potential adverse events related with cardioplegic arrest. beating heart surgery has avoided such complications and adapted to valve surgery following successful results published on myocardial revascularization. difficulty in weaning from cardiopulmonary bypass may be lessened by using on-pump beating heart surgery for mitral valve...

ital, T tal, Te c aort A 53-year-old woman presented to our center with progressive fatigue and dyspnea on exertion (New York Heart Association functional class III). The patient’s medical history was significant for multiple cardiac interventions: open mitral commissurotomy for the treatment of rheumatic mitral stenosis 30 years earlier, mitral valve replacement for the treatment of severe mit...

OBJECTIVES We sought to compare the maternal and fetal outcomes of patients with severe mitral stenosis submitted to percutaneous balloon dilation versus open mitral valve commissurotomy (MVC) during pregnancy. BACKGROUND Heart failure in patients with mitral stenosis complicating pregnancy is a common problem in developing countries. Since 1984, percutaneous dilation of the mitral valve usin...

BACKGROUND Valvular heart diseases and mainly rheumatic heart diseases complicate about 1% of pregnancies. During pregnancy physiological hemodynamic changes of the circulation are the main cause of mitral stenosis (MS) decompensation. Prior to introduction of percutaneous mitral balloon commissuroplasty (PTMC), surgical comissurotomy was the preferred method of treatment in patients with refra...

BACKGROUND Although plasma endothelin concentrations are elevated in patients with pulmonary hypertension, the precise sites of endothelin production have not been defined. We investigated the endothelin production in the pulmonary circulation of patients with mitral stenosis and its effects on pulmonary vascular tone. METHODS AND RESULTS We measured plasma concentrations of endothelin-1, ang...

The rate of redo surgeries are increasing on account of previously performed coronary artery bypass graft surgeries, aortic/ mitral valve replacement surgeries due to valve stenosis/ regurgitation, mitral valve repair for ischemic mitral regurgitation, the aging in the population, mechanical valve thrombosis and wearing out of the mechanical valves.Resternotomy, anterolateral right thoracotomy ...

Twelve newborn infants of poorly-controlled diabetic mothers were transferred from outlying maternity hospitals for neonatal intensive care. Respiratory distress and cardiomegaly were the presenting signs. Ten infants were large for dates (macrosomic) and had echocardiographic evidence of myocardial hypertrophy, reduced ejection time, and systolic anterior movement of the mitral valve (in 6 inf...

conclusions surgical repair of the congenital mv disease yields acceptable early and intermediate-term satisfactory valve function and good survival at intermediate-term follow-up. strong predictors for poor surgical outcome and death were age smaller than 1 year, weight smaller or equal than 6 kg, and associated cardiac anomalies such as pulmonary stenosis. objectives the aim of this study was...
