Pneumonectomy; Status clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Right Ventricle Function After Major Right Lung Resection

RIVER

Start date: November 8, 2019
Phase:
Study type: Observational

Major lung resection is associated with high post-operative morbidity and mortality and significant long-term decreased functional capacity, especially due to cardiorespiratory complications. RV (Right Ventricle) ejection, pulmonary artery pressure and tone are tightly coupled. The RV is exquisitely sensitive to changes in afterload. When pulmonary vascular reserve is compromised RV ejection may be also compromised, increasing right atrial pressure and limiting maximal cardiac output. Acute increase in RV outflow resistance, as may occur with acute pulmonary embolism will cause acute RV dilatation and, by ventricular interdependence, markedly decreased LV (Left Ventricle) compliance, rapidly spiraling to acute cardiogenic shock and death. Most of the studies on RV function after lung resection are small and have found different results, and sometimes conflicting findings. As far as the investigators know, there are no data on the incidence of the RV dysfunction after major lung resection (pneumonectomy/bilobectomy) and it's not clear if there is some direct association between the RV dysfunction and post-operative complications. If so, early detection of RV dysfunction after major lung resection could provide the opportunity for interventional therapy with consequent possible improvement of these patients' prognosis.
