Surgical Treatment of Infective Endocarditis in Pulmonary Position-15 Years Single Centre Experience.

Background and Objectives: Infective endocarditis in the pulmonary position is a rare disease. Isolated pulmonary valve endocarditis is extremely rare. The aim of our study was to assess patients who were treated surgically for pulmonary endocarditis at our institution from January 2003 to December 2017. Materials and Methods: We analyze eight cases of infectious endocarditis in pulmonary position out of 293 patients who were operated for infective endocarditis (2.7%, 8/293). Only two of these eight patients were not related to congenital heart malformation. They were followed for early and late mortality, long-term survival, postoperative morbidity and reoperations. Results: Among six patients suffering from congenital heart disease, four patients underwent corrections of pulmonary valve malformation previously, and their infected grafts were replaced by two allografts and two xenografts. The two other patients had replaced their infected pulmonary valves with allografts. Two non-congenital patients with pulmonary valve endocarditis underwent valve replacement with biological prosthesis. All patients survived the early postoperative course. The mean follow-up time was 9.1 (interquartile range (IQR), 5.3-12.6) years. The long-term follow-up included seven patients. One patient (12.5%, 1/8) died more than 4 years after the surgery due to sepsis. Pulmonary endocarditis was the rarest endocarditis treated surgically (p < 0.001). Conclusion: Surgery for infective endocarditis in the pulmonary position (IEPP) is an effective method of treatment with excellent early outcome and good late results despite a very uncommon pathology and few operations being performed. Surgery performed earlier may make the procedure less radical.

Comparison of early postoperative results between conventional and transapical mitral valve repair.

INTRODUCTION: Conventional mitral valve repair (CMVR) is well-established, safe and effective treatment for degenerative mitral regurgitation (MR). Transapical off-pump implantation of artificial chordae (TA) has been introduced into practice and gained interest among surgeons. However, there are no publications comparing the results between TA and CMVR. AIM: To compare early postoperative outcomes of CMVR with TA in patients with degenerative MR. MATERIAL AND METHODS: This was a retrospective cohort study. A total of 169 patients who underwent mitral valve repair between 2011 and 2018 were included in this analysis. Patients were divided into two groups: the TA group, n = 78 and CMVR group, n = 91. The groups were compared for early postoperative outcomes. RESULTS: Patients in the TA group were younger, 54.2 ±11.1 vs. 59.5 ±12.8 years (p = 0.005). Patients in the CMVR group had more complicated postoperative course with higher incidence of blood transfusion (42.9% vs. 7.8%, p = 0.001), atrial fibrillation (25.3% vs. 11.7%, p = 0.031), renal insufficiency (15.4% vs. 2.6%, p = 0.007) and stroke (2.1% vs. 0%). In the early postoperative period, one patient died in the TA group, and there were no deaths in the CMVR group (p = 0.277). Residual moderate to severe mitral regurgitation was present in nine (11.5%) TA patients, while none of the patients in the CMVR group had moderate or a higher degree of residual regurgitation (p = 0.001). CONCLUSIONS: Off-pump transapical MV repair is a feasible and safe procedure with low postoperative morbidity rates. Higher rates of mitral regurgitation reoccurrence would require a careful and thorough selection of the patients suitable for the TA approach.

Valvular heart disease during pregnancy: a clinical case and a literature review.

BACKGROUND: As a result of improved diagnostic and reparative techniques, congenital heart diseases are becoming a significant problem for women of childbearing age. Nowadays, more pregnant women in the West are being diagnosed with an acquired heart disease because of the tendency to delay childbearing and increasing age-related risk of developing complications of hypertension, diabetes, obesity and other diseases. According to the Lithuanian Health Information Centre, the incidence of cardiovascular diseases in pregnancy is decreasing in Lithuania, from 1.4% in 2014 to 1% in 2016 (1). Heart diseases can aggravate maternal adaptive capabilities and complications that pose a threat to mother and foetus can occur. Management of such conditions presents a serious therapeutic challenge to multidisciplinary team. The aim of this article is to discuss the course of pregnancy and peculiarities of maternal and foetal care in a woman with hemodynamically significant heart disease. MATERIALS AND METHODS: We present a clinical case of a 30-year-old nuliparous woman who was diagnosed with mitral valve disease with critical stenosis, grade II/III mitral valve insufficiency, moderate-severe pulmonary hypertension, heart failure stage C, and NYHA functional class II. RESULTS AND CONCLUSIONS: Pregnancy in conjunction with heart disease is a complicated condition that requires multidisciplinary prenatal care (consisting of an obstetrician gynaecologist, cardiologist, anaesthesiologist). Low molecular weight heparins should be the first choice medication for antithrombotic prophylaxis. Since pregnancy can aggravate a heart disease, preconception counselling and evaluation of the heart function are recommended.

30-year experience of Fontan surgery: single-centre's data.

BACKGROUND: The Fontan procedure has been modified several times since it was introduced into practice in 1968. As many patients now survive to adulthood, attention is directed towards their clinical status and late morbidity. We report our surgical experience of 30 years in Fontan procedures. METHODS: From January 1985 to January 2015, 80 patients underwent Fontan surgery. Twenty-one patients received an atrio-pulmonary Fontan (Group I), four patients underwent total cavopulmonary connection (TCPC) with an intra-atrial lateral tunnel (Group II), six patients received extra-cardiac TCPC with an aortic homograft (group III) and 49 patients received extra-cardiac TCPC with an expanded polytetrafluoroethylene conduit. They were followed for early and late mortality, long-term survival, postoperative morbidity and reoperations. RESULTS: The mean follow-up time was 7.4 ± 6.6 years. The Kaplan-Meier estimated 15-year survival rate was 42% in Group I, 50% in Group II, 83% in Group III and 94% in Group IV. The median length of stay in intensive care unit, intubation and chest drain stay time were 90 h (IQR, 46-119), 8 h (IQR, 6-16) and 18 days (IQR, 12-28) respectively. Early complications were bleeding (6), taken down of Fontan circulation (3) and acute heart failure managed by left heart bypass (1). Late-occurring morbidities included arrhythmias (6), protein-losing enteropathy (2), thromboembolism (2) and tracheal stenosis (1). Fourteen patients (18%) had redo Fontan procedures. CONCLUSION: Our series showed improving results after Fontan completion with excellent mid-term outcome after extra-cardiac TCPC with expanded polytetrafluoroethylene conduit. The long-term result should be followed.

UNLABELLED: Coarctation of the aorta is relatively common defect accounting for 5-8% of all congenital heart defects. Newborns very often, about in 50% of cases, are in cardiogenic shock. From 1991 to 2003, 26 neonates with coarctation of the aorta underwent surgical repair at Heart Surgery Center of Vilnius University: 12 with isolated coarctation of the aorta and 14 with leading heart pathology. Age of patients was from 2 to 30 days. Weight was from 2.8 to 4.7 kg. Fifty percent of neonates were on ventilatory and inotropic support. All neonates were operated using surgical technique "end-to-end" or extended "end-to-end" in case of aortic arch hypoplasia. All neonates with isolated coarctation of the aorta survived; with leading heart pathology mortality was 14.3%. From 26 operated neonates 2 had recoarctation, 1 - reoperation and 2 - balloon aortoplasty. Our patients were free from spinal chord ischemia and brain damage. CONCLUSIONS: Neonatal coarctation of the aorta needs an urgent surgical treatment. Surgery remains a gold standard for the treatment of aorta coarctation. Preferable technique is "end-to-end" anastomosis or extended coarctation resection with "end-to-end" anastomosis for hypoplastic aortic arch. Associated cardiac pathology increases risk of operation.

From January 1974 trough August 2002 184 neonates with congenital heart disease underwent surgical repair in Heart Surgery Clinic of Vilnius University. It came to 3.8% of all 4813 procedures of congenital heart diseases performed. Number of neonates operations considerably increased in the latter's years, because special Department with proper technique was established. One hundred and seven neonates were operated without cardiopulmonary bypass with 36.4% postoperative mortality rate. Seventy seven neonates underwent surgery repair with cardiopulmonary bypass. Postoperative mortality rate was 67.5% in this group. Mean age of patients was 11.96+/-0.28 days. Unsatisfactory results of neonates operations with cardiopulmonary bypass, especially such as left heart hypoplasia syndrome is the main problems. The group of specialists performing repair of congenital heart diseases is working actively in the heart Surgery Clinic of Vilnius University. Improvement of surgery methods and results, following the best Heart Surgery Clinics of the world, is the main purpose of this group.
