BACKGROUND Pulmonary arterial hypertension is a severe and progressive disease. Its early diagnosis is the greatest clinical challenge. OBJECTIVE To evaluate the presence and extension of the delayed myocardial contrast-enhanced cardiovascular magnetic resonance, as well as to verify if the percentage of the myocardial fibrosis mass is a severity predictor. METHODS Cross-sectional study wit...

BACKGROUND Right ventricular failure (RVF) and -support is associated with poor results. We aimed for a new approach of right - sided assistance bypassing the right ventricle and pulmonary circulation in order to better decompress the right ventricle and optimize left ventricular filling. METHODS From a microaxial pump (Abiomed), a low resistance oxygenator (Maquet and Novalung) and two cannu...

Introduction Acute respiratory distress syndrome (ARDS) is responsible for injuries to the alveolar epithelium and microvascular endothelium resulting in hypoxemia, decreased pulmonary compliance and increased pulmonary vascular resistance. Beneficial effects resulting from protective lung ventilation are counterbalanced by deleterious hemodynamic effects. Indeed, hypercapnia resulting from ven...

Electrophysiological, hemodynamic and angiographic studies were performed on an 18 year old woman with asymptomatic recurrent bidirectional tachycardia of eight years' duration and mild hyperkalemic periodic paralysis. Multiple surface electrocardiograms and His bundle and right atrial electrograms revealed that 1) all beats during bidirectional tachycardia originated in the left ventricle; 2) ...

OBJECTIVE Mortality and morbidity related to right ventricular failure remain a problem for the long-term outcome of congenital heart diseases. Therapeutic innovation requires establishing an animal model reproducing right ventricular dysfunction secondary to chronic pressure-volume overload. METHODS Right ventricular tract enlargement by transvalvular patch and pulmonary artery banding were ...

Although compressed gas (CO2) blowers have been used safely to aid accurate grafting during off-pump coronary bypass surgery, hemodynamic collapse due to gas embolism into the right coronary artery may occur. Supportive measures to facilitate gas clearance by increasing the coronary perfusion pressure have been reported to be successful in restoring hemodynamic stability. However, right ventric...

A 47 year-old female died after mitral valve replacement. Post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. At microscopic examination, diffuse right ventricular fatty infiltration was found. We found no previous report of this pathology in patients with mitral stenosis

Traditionally a homograft valve is used as a pulmonary replacement device for the Ross operation. Right ventricular outflow tract reconstruction during aortic valve replacement with an autograft was performed with stentless xenograft valves in nine patients. Hemodynamic performance is satisfying, but, long term evaluation is needed.
