Background: High levels of arterial oxygen pressures (PaO) have been associated with increased mortality in extracorporeal cardiopulmonary resuscitation (ECPR), but there is limited information regarding possible mechanisms linking hyperoxia and death in this setting, notably with respect to its hemodynamic consequences. We aimed therefore at evaluating a possible association between PaO, circulatory failure and death during ECPR.
Methods: We retrospectively analyzed 44 consecutive cardiac arrest (CA) patients treated with ECPR to determine the association between the mean PaO over the first 24 h, arterial blood pressure, vasopressor and intravenous fluid therapies, mortality, and cause of deaths.
Background: Early treatment of aortic valve stenosis is recommended in eligible symptomatic patients with severe aortic valve stenosis who would otherwise have a poor prognosis. The sutureless aortic valve bioprosthesis offers an alternative to standard aortic valve replacement with a sutured valve, but limited data are available in patients who have undergone multiple valve procedures involving the new, sutureless technology. We sought to investigate outcomes in high operative risk patients with previous or concomitant valve surgery who were implanted with a sutureless valve.

Acute decompensation of ES in conditions promoting a further increase of pulmonary vascular resistance, such as pulmonary embolism or pneumonia, can precipitate major arterial hypoxia and death. In such conditions, increasing systemic oxygenation with veno-venous extracorporeal membrane oxygenation (VV-ECMO) could be life-saving, serving as a bridge to treat a potential reversible cause for the decompensation, or to urgent lung transplantation.

These SU-RD valves, inspired by the TAVI (Transcatheter Aortic Valve Implantation), allow significant operating time reduction and facilitate minimally invasive surgery. They are particularly indicated for patients that are more fragile and in combined procedures (for example AVR associated with coronary bypass surgery).

Among its potential complications, VA-ECMO may adversely affect lung function through various pathophysiological mechanisms. The interaction of blood components with the biomaterials of the extracorporeal membrane elicits a systemic inflammatory response which may increase pulmonary vascular permeability and promote the sequestration of polymorphonuclear neutrophils within the lung parenchyma.

Early outcome prediction is crucial in this setting, but data on neuroprognostication are limited. We examined the prognostic value of clinical neurologic examination, using an automated device for the quantitative measurement of pupillary light reactivity.

However, ensuing consequences are often dire, and its surgical treatment poses unique problems, due to the frequent underlying frailty of TAVI recipients.

This response can, in severe cases, lead to systemic hypotension and organ dysfunction. Cytokine removal might therefore improve outcomes of patients undergoing cardiac surgery.

Solitary fibrous tumors are rare mesenchymal tumors most commonly arising from the pleura. When associated with paraneoplastic syndrome of hypoglycemia caused by the secretion of a high-molecular-weight form of insulin-like growth factor II, it is referred to as the Doege-Potter syndrome. Surgery with complete tumor resection is the only curative treatment.

Presentation Of Case: We report the case of a 52-year-old man presenting a paraganglioma just above the carina with obstructive symptoms. The patient successfully underwent a non-circumferential tracheal membranous resection, followed by latissimus dorsi muscle flap repair, under peripheral extra-corporeal membrane oxygenation (ECMO).
Fenestrated aortic valve is a frequent condition which is, for most of the time, asymptomatic and generally has no influence on aortic valve competence. However, aortic valve regurgitation could occur, especially in the case of fibrous strand rupture. In this situation, acute aortic regurgitation is poorly tolerated and requires urgent surgical correction.

A 74-year-old woman was admitted for right coronary angioplasty. During the procedure, she complained about chest pain, and contrast injection showed an iatrogenic dissection of the ascending aorta. A contrast computed tomography (CT) scan confirmed the diagnosis via visualization of a large non-circulating false lumen, which involved nearly the entire ascending aorta.

The worsening of a mitral regurgitation led to investigations and surgery. The valve presented marked distortion and thickening by type AL amyloid associated with a monotypic CD138+ immunoglobulin lambda plasma cell proliferation.

A QAV associated with an ascending aorta aneurysm is an extremely rare anatomic combination with a hypothetical, but not clear, shared embryological etiology. To date, only two cases of type B QAV with ascending aorta aneurysm have been reported.

Minimally invasive direct coronary artery bypass grafting is also a valid, minimally invasive option for myocardial revascularization in patients with critical stenosis on the anterior descending coronary artery. Both procedures are performed through a left minithoracotomy, without cardiopulmonary bypass, aortic cross-clamping, and cardioplegic arrest.

Seven days later the echocardiography showed acute severe aortic valve insufficiency. Intraoperatively we found a perforated leaflet probably due to lesion during transcatheter procedure.
