The purpose of this study was to assess shortterm effects of transjugular intrahepatic shunt (TIPS) on cardiac function with cardiac magnetic resonance imaging (MRI) in patients with liver cirrhosis. Eleven patients (six males and five females) with intractable esophageal varices or refractory ascites were imaged with MRI at 1.5 T prior to, within 24 h after, and 4-6 months after TIPS creation (n = 5). Invasive pressures were registered during TIPS creation. MRI consisted of a stack of contiguous slices as well as phase contrast images at all four valve planes and perpendicular to the portal vein. Imaging data were analyzed through time-volume curves and first derivatives. The portoatrial pressure gradient decreased from 19.8 + or = 2.3 to 6.6 + or = 2.3, accompanied by a nearly two fold increase in central pressures and pulmonary capillary wedge pressure immediately after TIPS creation. Left and right end diastolic volumes and stroke volumes increased by 11, 13, and 24%, respectively (p\0.001), but dropped back to baseline at follow-up. End systolic volumes remained unchanged. E/A ratios remained within normal range. During follow-up the left ventricular mass was larger than baseline values in all patients, with an average increase of 7.9 g (p\0.001). In conclusion, the increased volume load shunted to the heart after TIPS creation transiently exceeded the preload reserve of the right and left ventricle, leading to significantly increased pulmonary wedge pressures and persistent enlargement of the left and right atria. Normalization of cardiac dimensions was observed after months together with mild left ventricular hypertrophy.

Non-alcoholic fatty liver disease (NAFLD) is the most frequent cause of liver damage and alteration of hepatic enzymes. NAFLD is strongly associated with metabolic syndrome and obesity. It is characterized by fat accumulation in the liver that may progress throughout hepatic steatosis and inflammation (non-alcoholic steatohepatitis [NASH]) toward cirrhosis and liver failure. In the last decade several studies suggested that NAFLD is an independent cardiovascular risk factor that increases cardiovascular mortality. At present, several studies investigating possible therapeutic approaches are ongoing. The present review is focused on the current and promising treatments of NAFLD.

Transcatheter arterial chemoembolization (TACE) offers a survival benefit to patients with intermediate hepatocellular carcinoma (HCC). A widely accepted TACE regimen includes administration of doxorubicin-oil emulsion followed by gelatine sponge-conventional TACE. Recently, a drug-eluting bead (DC Bead) has been developed to enhance tumor drug delivery and reduce systemic availability. This randomized trial compares conventional TACE (cTACE) with TACE with DC Bead for the treatment of cirrhotic patients with HCC. Two hundred twelve patients with Child-Pugh A/B cirrhosis and large and/or multinodular, unresectable, N0, M0 HCCs were randomized to receive TACE with DC Bead loaded with doxorubicin or cTACE with doxorubicin. Randomization was stratified according to Child-Pugh status (A/B), performance status (ECOG 0/1), bilobar disease (yes/no), and prior curative treatment (yes/no). The primary endpoint was tumor response (EASL) at 6 months following independent, blinded review of MRI studies. The drug-eluting bead group showed higher rates of complete response, objective response, and disease control compared with the cTACE group (27% vs. 22%, 52% vs. 44%, and 63% vs. 52%, respectively). The hypothesis of superiority was not met (one-sided P = 0.11). However, patients with Child-Pugh B, ECOG 1, bilobar disease, and recurrent disease showed a significant increase in objective response (P = 0.038) compared to cTACE. DC Bead was associated with improved tolerability, with a significant reduction in serious liver toxicity (P < 0.001) and a significantly lower rate of doxorubicin-related side effects (P = 0.0001). TACE with DC Bead and doxorubicin is safe and effective in the treatment of HCC and offers a benefit to patients with more advanced disease.

This investigation aimed to evaluate patient characteristics and procedural factors associated with abnormal nephrograms encountered on noncontrast computed axial tomography (CAT) obtained 24-h after transarterial chemoembolization (TACE) for primary and metastatic hepatic malignancies. Sixty hepatic chemoembolization procedures were performed in 29 patients who had a median age of 63 years (range 42-79). The male-to-female ratio was 16:13. Noncontrast CAT scans were obtained approximately 24 h after TACE as part of our institutional protocol and were examined for persistent renal nephrograms. These findings were compared with clinical and procedural parameters to determine whether there was any association with these factors or with the occurrence of acute renal failure (ARF). Abnormally persistent CAT nephrograms were observed 24 h after 28 of 60 (46.7%) TACE procedures, of which 14 (23.3%) were persistent, bilaterally dense, global nephrograms, and 14 (23.3%) were small, wedge-shaped, and focal nephrograms. The change in serum creatinine from baseline to 24 h was significantly greater (p=0.031) in the global nephrogram group. The presence of cirrhosis, Child-Pugh score, procedure time, baseline renal insufficiency, and lower periprocedural mean arterial blood pressure were also statistically significantly associated with the occurrence of bilateral globally dense nephrograms. The procedure time was statistically significantly associated with the occurrence of wedge-like focally persistent nephrograms. Global, persistently dense nephrograms and wedge-shaped focally persistent nephrograms are not infrequently observed after TACE. Persistent global nephrograms can be an important clinical indicator of ARF. The wedge nephrogram may represent focal renal ischemia.

Vascular invasion of supra-hepatic veins (SHV) is a major complication of primary liver tumours. The tumorous thrombus, when extended to the vena cava and right atrium, may produce occlusion of the tricuspid valve or pulmonary embolism with sudden cardiac death. The presence of macroscopic vascular infiltration represents an advanced stage of the tumour contraindicating liver transplantation, thus liver resection with thrombectomy is the only therapeutic option in this setting despite the concerns of postoperative liver failure and the dismal results at distance. A 45-year-old male with chronic active hepatitis/cirrhosis was referred to our department for a tumour in the left hemi-liver with infiltration of the left-middle hepatic veins and a tumour thrombus extension to the right atrium. We reported a successful cavo-atrial thrombectomy, along with left hemi-hepatectomy, under hypothermic cardio-circulatory arrest (HCA). To our knowledge, this technique has been used only once for primary liver cancer on chronic liver disease, this being the second case reported in literature. We conclude that this technique should be considered for atrial thrombi removal in patients affected by liver tumours in the presence of a healthy liver or of a well compensated liver cirrhosis in order to prolong the patient's life span.

Atrial septal defects constitute the second most common cardiac congenital abnormality. These defects when undiagnosed during childhood, present in adulthood with symptoms of right heart failure. We describe a case of uncorrected ostium primum atrial septal defect that presented as liver failure in a 43-year-old woman. The patient was found to have liver cirrhosis and a complete work-up of hepatic causes for cirrhosis was negative. Further examination revealed an atrial primum septal defect. Liver cirrhosis in this patient was thought to be secondary to chronic congestion from the right heart failure resulting from the atrial septal defect. Although right heart failure is a known cause of cirrhosis, liver cirrhosis resulting specifically from an atrial septal defect is uncommon. In fact, an ostium primum atrial septal defect presenting as liver cirrhosis has not been well described. We present such a case to highlight this manifestation of atrial septal defect and also to reiterate that cardiac causes should always be considered in the differential diagnosis whenever a patient presents with liver cirrhosis.

Marked hemodynamic changes occur in humans and experimental animals with cirrhotic liver disease. In the heart, basal contractility, responsiveness to beta-adrenoceptor activation, and excitation-contraction coupling (ECC) are negatively affected in models of cirrhosis and portal hypertension with portosystemic shunting (PVS), and comprise what has been called cirrhotic cardiomyopathy. These effects are accompanied by elevated circulating levels of bile acids. We investigated whether elevated bile acids act as a myocardial toxicant by exposing cardiac muscle in vitro to bile acids and compared these results with two models of cirrhotic cardiomyopathy with elevated bile acids: CCl4-induced cirrhosis and PVS. Cholic acid, a lipophilic bile acid, produced a decrease in basal cardiac contractility and responsiveness to beta-adrenoceptor activation, both of which appeared to result from altered ECC. beta-Adrenoceptor density and signaling were unaffected. Acutely, ursodeoxycholic acid, a more hydrophilic bile acid, had no effect. Cirrhosis produced a decrease in basal force, depressed beta-adrenoceptor responsiveness, and altered ECC similar to cholic acid. However, cirrhosis also altered beta-adrenoceptor signaling including decreases in cyclic AMP formation, expression of the stimulatory G protein, GS, and beta-adrenoceptor density. Displacement of lipophilic bile acids by chronic administration of ursodeoxycholic acid to rats during the development of cirrhotic cardiomyopathy produced by PVS produced attenuation of the effect on ECC. These results suggest a possible role for lipophilic bile acids in some, but not all of the myocardial consequences of chronic portal vein stenosis and CCl4-induced cirrhosis.

Surgical treatment in hepatocellular carcinoma patients with cardiac involvement is challenging, and its prognosis remains unclear because of its rarity. A 48-year-old male hepatocellular carcinoma patient presented with right atrial involvement through the inferior vena cava and a left atrial mass, which nearly occluded the mitral valve, and extended from a pulmonary metastasis. Emergent surgery was performed due to sudden severe respiratory failure despite profound liver cirrhosis (Child-Pugh class B). Nevertheless, the patients postoperative course was uneventful, and over six months of follow-up, he has shown no remarkable symptoms and has maintained a tolerable liver function.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether patients with liver cirrhosis have acceptable outcomes after undergoing cardiac surgery. Altogether 97 papers were found using the reported search, of which nine presented the best evidence to answer the clinical question. The author, year, journal, country of study, study type, patient group studied, relevant outcomes, results and study weaknesses were tabulated. One prospective and another eight retrospective studies involving adult population of patients with liver cirrhosis undergoing various cardiac surgical procedures were selected. In these studies, the overall mortality was 17.1% and combined mean mortality for Child-Pugh class A, B and C was 5.2%, 35.4% and 70%, respectively. The major morbidity ranged from 20 to 60% in group A and 50 to 100% in the patients with more advanced hepatic disease. Some studies have demonstrated that thrombocytopenia, decreased serum cholinesterase and high preoperative total bilirubin levels are significantly associated with worse clinical outcomes. These studies, although with small samples, collectively demonstrate that patients with Child-Pugh class A cirrhosis tolerated cardiac surgical procedures with a mild increase in mortality and morbidity. However, the risk of mortality in patients with Child-Pugh class B and C or MELD score>13 is extremely high. Nevertheless, even if these patients underwent successful surgery, their long-term survival was significantly poorer and their health status remains compromised even well after cardiac surgery because of persistent liver dysfunction.

We report a case of successful treatment of a mycotic aneurysm of the thoracic aorta. A 65-year-old man with a dissecting aneurysm presented with urinary tract infection. He had a history of severe liver cirrhosis. Two weeks after admission, he had a high-grade fever and enhanced computed tomography (CT) demonstrated acute expansion of the distal aortic arch aneurysm. Because of the acute aneurysm expansion and elevated inflammatory response, we suspected a mycotic aortic aneurysm with possible impending rupture. Since conventional open chest surgery was considered to carry a high operative risk, the patient was managed with a combination of emergency endovascular treatment and antibiotic chemotherapy. Extended-spectrum beta-lactamase-producing Escherichia coli were identified from blood culture before treatment. After strict antibiotic therapy, the postoperative course was uneventful and the patient remained well 12 months later.
