Levosimendan In Patients Undergoing LVAD Implantation

Left Ventricular DysfunctionRight Ventricular Dysfunction1 more

According to the results from the literature, it has been shown that levosimendan usage 24-48 hours before LVAD implementation can improve short and long-term outcome in these patients regarding to the patients without preoperative pretreatment. The aim is to compare short and long-term outcome in patients who underwent to LVAD implementation and pretreated with levosimendan regarding the patient without pretreatment or with other medications.

Pulmonary Vasculature and Right Heart Dysfunction in Chronic Obstructive Pulmonay Disease

COPDPulmonary Vascular Disorder1 more

The pulmonary vasculopathy and right heart dysfunction in COPD are drawing increasing attention these days. Recent researches show that pulmonary vasculopathy and right heart dysfunction relate to greater severity in COPD. Applying appropriate modalities for early detection of pulmonary vasculopathy and right heart dysfunction is of great importance. What's more, the interaction mechanism between pulmonary vasculature, right heart and COPD still needs to be further studied. The aim of our study is to develop an assessment system of pulmonary vasculopathy and right heart dysfunction in COPD patients and elucidate their impact on COPD course and outcome.

Femoral Venous Pulsatility and Right Heart Dysfunction in Heart Surgery: An Observational Study...

Heart; Dysfunction PostoperativeCardiac Surgery2 more

Right heart failure during cardiac surgery is associated with increased perioperative morbidity and mortality. In this context, it is imperative to develop simple diagnostic tools to detect right heart failure. The purpose of this observational study is to determine if ultrasound Doppler of the femoral vein can detect and predict right ventricular failure after cardiac surgeries requiring cardiopulmonary bypass. It is expected that an elevated pulsatility of the femoral vein before the induction of general anesthesia is associated with perioperative right heart failure.

Right Ventricle Function After Major Right Lung Resection

Right Ventricular DysfunctionPneumonectomy; Status

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.

Emergency Department Assessment of Right Ventricular Function and Size in the Post Cardiac Arrest...

Right Ventricular DysfunctionCardiac Arrest

The right side of the heart of often overlooked in patients who are acutely unwell, as the main area of focus when performing echocardiography tends to be the left ventricle. The right ventricle can yield important diagnostic clues that can aid the clinician, particularly in cases where one may suspect elevated right sided pressures, such as those due to a pulmonary embolus. Although it is taught that a dilated right ventricle is associated in patients with pulmonary embolus, but in patients with spontaneous circulation. What is unknown is patients who sustain a cardiac arrest, does the same hold true. There is a paucity of literature surrounding the appearance of the right ventricle in the cardiac arrest patient acutely. This study aims to assess right ventricular size and function in the immediate post cardiac arrest phase.
