Right ventricular failure is a major contributor to increased morbidity and mortality in patients undergoing left ventricular assist device implantation. Cardiopulmonary bypass is associated with increased pulmonary ischaemia and pulmonary vascular resistance. Continuous pulmonary perfusion and ventilation represents an emerging strategy for pulmonary protection during cardiac surgery. We hypothesize that ...

Recognition of the cardiac origin of weaning failure is a crucial issue for successful discontinuation of mechanical ventilation. Bedside lung ultrasound and echocardiography have shown a potential in predicting weaning failure. Objective of this report was to describe the case of a patient repeatedly failing to wean from mechanical ventilation, ...

The Mustard procedure is a palliative surgical procedure used to repair complete transposition of the great arteries. Cardiac transplantation remains the only definitive therapy for patients who develop heart failure after a Mustard procedure. However, pulmonary hypertension represents a major hemodynamic contraindication. The use of a ventricular assist device as ...

Patients with chronic obstructive pulmonary disease (COPD) show a poor prognosis after myocardial infarction (MI) and percutaneous coronary intervention (PCI). We evaluated on-treatment platelet reactivity (PR) and several gene polymorphisms related to PR in 130 patients undergoing PCI with and without COPD. Those with concomitant COPD showed higher on-treatment PR ...

The high prevalence of patients with heart failure (HF) with preserved ejection fraction (HFpEF) has highlighted the pivotal role of diastolic function in the development of HF. Abnormalities of diastolic function induce elevated left ventricular (LV) end-diastolic pressure, which leads to pulmonary edema and the symptoms of HF because the ...

BACKGROUND: Lung diffusion for carbon monoxide (DL(CO)) has been shown to associate with the risk of pulmonary arterial hypertension development and, most likely, with right ventricular (RV) myocardial dysfunction in sarcoidosis patients. Besides its known role as a marker of left ventricular dysfunction, experimental evidence suggests a role of NT-proAtrial ...

Among life-threatening cardiovascular diseases, pulmonary embolism (PE) is the third most common after myocardial infarction and stroke. PE is a manifestation of venous thromboembolism (VTE). PE shares risk factors with deep vein thrombosis (DVT) and is regarded as a consequence of DVT rather than a separate clinical entity. Risk factors ...

A 56-year-old smoker presented with a 3-day history of intermittent chest pain. Cardiovascular examination on admission was normal. ECG showed minimal (<1 mm) ST elevation in lead III, and right-sided leads revealed similar mild ST-elevation. Troponin I was elevated at 10.91. He was managed as a delayed-presentation ST-elevation myocardial infarction ...

OBJECTIVE: Right ventricular (RV) failure during left ventricular assist device (LVAD) support can result in severe hemodynamic compromise with high mortality. This study investigated the acute effects of cavo-pulmonary anastomosis on LVAD performance and RV myocardial compromise in comparison with biventricular circulatory support, in a model of biventricular failure. METHODS: ...

It is has been suggested that dialysis patients have lower mortality rates for pulmonary embolism than the general population, because of platelet dysfunction and bleeding tendency. However, there is limited information whether dialysis is indeed associated with a decreased mortality risk from pulmonary embolism. The aim of our study was ...

AIMS: Although complex fractionated atrial electrograms (CFAEs) are purported to represent critical sites for atrial fibrillation (AF) perpetuation, the mechanism and the significance of CFAE in the genesis of AF remain poorly understood. This study evaluated the relationship between CFAE and areas of abnormal atrial tissue defined by low-voltage electrograms ...

OBJECTIVES: Patients with pulmonary atresia and intact ventricular septum (PA-IVS) may have coronary sinusoids connected to a hypertensive right ventricle. Coronary perfusion may then completely depend on the right ventricular systolic pressure wave; decompression of the right ventricle can be deleterious in these patients. This study was set to investigate ...

Abstract  Patients with hypoplastic left heart syndrome (HLHS) with intact or severely restrictive atrial septum have slow resolution of their elevated pulmonary vascular resistance after left atrial decompression. We report two neonates who required urgent surgical intervention because of unusually rapid fall in their pulmonary vascular resistance following left atrial ...

BACKGROUND: Chest pain is a frequent symptom leading patients to the Emergency Room. Copeptin, the C-terminal fragment of arginin-vasopressin, is a marker of stressful situations. Recent studies showed that normal levels of copeptin combined with normal troponin accurately rule out the diagnosis of acute coronary syndrome (ACS). In this observational, ...

Elevation in plasma activity of von Willebrand factor (vWF) reflects endothelial dysfunction and predicts death in pulmonary arterial hypertension. Higher vWF activity is also associated with a lower right ventricular (RV) ejection fraction in pulmonary arterial hypertension. Little is known about the relation between vWF and RV structure and function ...

Pulmonary valve regurgitation is the most common complication after complete repair of tetralogy of Fallot. The benefits of pulmonary valve replacement (PVR) on right ventricular (RV) volumes is well established. However, the effect on left ventricular (LV) function is still debated. We aimed to determine the evolution of LV function ...
