Background: In cirrhotic patients intra-abdominal pressure (IAP) changes markedly modify splanchnic and systemic hemodynamics. Previous studies have evaluated the effects of increased IAP on steady-state cardiac performance, showing that right ventricular (RV) function becomes more depressed than that of the left ventricular. We sought to evaluate the effects of paracentesis on RV function and ventricular-arterial coupling among cirrhotics undergoing liver transplantation (OLT).
Methods: Twelve cirrhotic patients undergoing OLT underwent hemodynamic profiles before and 5 minutes after paracentesis, employing a right ventricular ejection fraction catheter in the pulmonary artery. We studied heart rate, systolic pulmonary artery pressure, central venous pressure (CVP), stroke volume index (SVI), RV end-diastolic volume index (RVEDI), and RV ejection fraction. In addition RV stroke work index (RVSWI), RV end-diastolic compliance (RVEDC), RV end-systolic elastance (Ees), pulmonary artery effective elastance (Ea), and RV coupling efficiency (Ees/Ea ratio) were calculated employing standard formulas.
Results: After removal of mean ascites volume of 5.6 +/- 2.2 L (range 4.0 to 8.04 L), SVI, RVEDI, RVSWI, and RVEDC were significantly increased and conversely CVP, Ees, and Ea were decreased with an ea/ea ratio unchanged.
Conclusions: Before paracentesis Ees/Ea is preserved by increased of RV contractility; after paracentesis the coupling was maintained.

Massive Central Pulmonary Embolism with Riding Embolus and Concomitant Aortic Arch Embolism-Should We Diagnose Patients Earlier for Blood Clotting Disorders? Case Report.

Paradoxical embolism occurs when a clot originates in the venous system and traverses through a pulmonary or intracardiac shunt into the systemic circulation, with a mortality rate of around 18%. The risk factors for arterial embolism and venous thrombosis are similar, but different disease entities can lead to a hypercoagulable state of the blood, including antithrombin III (AT III) deficiency. We report the case of a 43-year-old man with a massive central pulmonary embolism with a rider embolus and concomitant aortic arch embolism with involvement of the brachiocephalic trunk, bilateral subclavian and axillary arteries, and the right vertebral artery, followed by a secondary ischaemic stroke.

Hospitalisation for acute decompensated heart failure (HF) portends a poor prognosis. Fluid retention manifesting in dyspnoea and oedema are important clinical features of decompensated heart failure and drive hospital admissions. Intracardiac and pulmonary artery pressure (PAP) monitoring can help predict heart failure decompensation, as changes in these haemodynamics occur before clinical congestion manifests.

Objectives: The impact of long-term complications after robotic hybrid coronary revascularization (HCR), including persistent angina, repeat revascularization, and myocardial infarction (MI), remains limited. This study aims to determine the risk factors for coronary events after robotic HCR and their time-varying effects on outcomes.
Methods: We identified all consecutive patients who underwent robotic HCR at our institution.
