Minimally invasive aortic valve replacement with orthotopic liver transplantation: report of a case

Simultaneous Live Donor Liver Transplantation, Aortic Valve Replacement, and Atrial Septal Defect Repair in a Patient With End Stage Liver Disease: A Case Report

Valvular heart disease creates an important barrier for orthotopic liver transplantation in patients with end-stage liver disease and increases mortality. Selection of the appropriate surgical scheme and adequate postoperative management can be lifesaving in these cases. This study presents a 32-year-old man diagnosed with hepatitis C-associated cirrhosis and severe aortic regurgitation due to subacute bacterial endocarditis. Initially, simultaneous aortic valve replacement (AVR) and live donor liver transplantation (LDLT) was planned. However, intraoperative transesophageal echocardiography revealed an additional atrial septal defect (ASD) and AVR, ASD repair, and LDLT surgery were performed. During the 2-year follow-up period, there were no early or late complications. To the best of our knowledge, this is the first patient to have simultaneous AVR, ASD repair, and LDLT surgery. Additionally, the present case is also unique in being the first person in the Republic of Azerbaijan to undergo concomitant cardiac surgery and LDLT.

Liver transplantation and cardiac illness: Current evidences and future directions

Contraindications to liver transplantation are gradually narrowing. Cardiac illness and chronic liver disease may manifest independently or may be superimposed on each other due to shared pathophysiology. Cardiac surgery involving the cardiopulmonary bypass in patients with Child-Pugh Class C liver disease is associated with a high risk of perioperative morbidity and mortality. Liver transplantation involves hemodynamic perturbations, volume shifts, coagulation abnormalities, electrolyte disturbances, and hypothermia, which may prove fatal in patients with cardiac illness depending upon the severity. Additionally, cardiovascular complications are the major cause of adverse postoperative outcomes after liver transplantation even in the absence of cardiac pathologies. Clinical decision-making has remained an unsettled issue in these clinical scenarios. The absence of randomized clinical studies has further crippled our endeavours for a consensus on the management of patients with end-stage liver disease with cardiac illness. This review seeks to address this complex clinical setting by gathering information from published literature. The management algorithm in this review may facilitate clinical decision making and augur future research.

Cardiac diseases among liver transplant candidates

Improvements in early survival after liver transplant (LT) have allowed for the selection of LT candidates with multiple comorbidities. Cardiovascular disease is a major contributor to post-LT complications. We performed a literature search to identify the causes of cardiac disease in the LT population and to describe techniques for diagnosis and perioperative management. As no definite guidelines for preoperative assessment (except for pulmonary heart disease) are currently available, we recommend an algorithm for preoperative cardiac work-up.

Transfemoral Transcatheter Aortic Valve Replacement for Mixed Aortic Valve Disease in Child’s Class C Liver Disease Prior to Orthotopic Liver Transplantation

The American Association for the Study of Liver Diseases practice guidelines list severe cardiac disease as a contraindication to liver transplantation. Transcatheter aortic valve replacement has been shown to decrease all-cause mortality in patients with severe aortic stenosis who are not considered candidates for surgical aortic valve replacement. We report our experience of liver transplantation in a patient with severe aortic stenosis and moderate aortic insufficiency who underwent transcatheter aortic valve replacement with Child-Pugh Class C disease at a Model For End-Stage Liver Disease score of 29. The patient had a difficult post procedure course that was successfully medically managed. After liver transplantation the patient was discharged to home on postoperative day 11. The combination of cardiac disease and end stage liver disease is challenging but these patients can have a successful outcome despite very severe illness.

Transcatheter aortic valve replacement for native aortic valve regurgitation as a bridge to liver transplantation

Coexistence of end-stage liver disease (ESLD) and severe valvular heart disease conveyed substantial risk for patients, oftentimes leading to exclusion from liver transplantation candidacy due to inability to safely offer cardiac surgery prior to transplantation. Several approaches have been described, including performing transplantation and valve surgery concurrently, or in sequence. Both options, however, have associated complications: catastrophic repercussion of peri-operative coagulopathy and organ dysfunction post-transplantation, respectively. The introduction of transcatheter procedures offered a safer alternative for high-risk patients; however, its recognized indications remained limited. A novel approach to this surgical dilemma by performing transcatheter aortic valve replacement (TAVR) for severe native aortic valve regurgitation in a patient on the liver transplant list has been presented. The procedure proved to be an effective management for the aortic valve insufficiency, improving our patient's hemodynamics in preparation for the subsequent orthotopic liver transplantation (OLT). © 2015 Wiley Periodicals, Inc.
