Pericardiectomy for constrictive pericarditis: a risk factor analysis for early and late failure

Predictors of early and late failure of pericardiectomy for constrictive pericarditis (CP) have not been established. Early and late outcomes of a cumulative series of 81 (mean age 60\ua0years; mean EuroSCORE II, 3.3%) consecutive patients from three European cardiac surgery centers were reviewed. Predictors of a combined endpoint comprising in-hospital death or major complications (including multiple transfusion) were identified with binary logistic regression. Non-parametric estimates of survival were obtained with the Kaplan\u2013Meier method. Predictors of poor late outcomes were established using Cox proportional hazard regression. There were 4 (4.9%) in-hospital deaths. Preoperative central venous pressure > 15\ua0mmHg (p = 0.005) and the use of cardiopulmonary bypass (p = 0.016) were independent predictors of complicated in-hospital course, which occurred in 29 (35.8%) patients. During follow-up (median, 5.4\ua0years), preoperative renal impairment was a predictor of all-cause death (p = 0.0041), cardiac death (p = 0.0008), as well as hospital readmission due to congestive heart failure (p = 0.0037); while partial pericardiectomy predicted all-cause death (p = 0.028) and concomitant cardiac operation predicted cardiac death (p = 0.026), postoperative central venous pressure < 10\ua0mmHg was associated with a low risk both of all-cause and cardiac death (p < 0.0001 for both). Ten-year adjusted survival free of all-cause death, cardiac death, and hospital readmission were 76.9%, 94.7%, and 90.6%, respectively. In high-risk patients with CP, performing pericardiectomy before severe constriction develops and avoiding cardiopulmonary bypass (when possible) could contribute to improving immediate outcomes post-surgery. Complete removal of cardiac constriction could enhance long-term outcomes

Acute mesenteric ischaemia in refractory shock on veno-arterial extracorporeal membrane oxygenation

Background: Acute mesenteric ischaemia is a severe complication in critically ill patients, but has never been evaluated in patients on veno-arterial extracorporeal membrane oxygenation (V-A ECMO). This study was designed to determine the prevalence of mesenteric ischaemia in patients supported by V-A ECMO and to evaluate its risk factors, as well as to appreciate therapeutic modalities and outcome. Methods: In a retrospective single centre study (January 2013 to January 2017), all consecutive adult patients who underwent V-A ECMO were included, with exclusion of those dying in the first 24 hours. Diagnosis of mesenteric ischaemia was performed using digestive endoscopy, computed tomography scan or first-line laparotomy. Results: One hundred and fifty V-A ECMOs were implanted (65 for post-cardiotomy shock, 85 for acute cardiogenic shock, including 39 patients after refractory cardiac arrest). Overall, median age was 58 (48-69) years and mortality 56%. Acute mesenteric ischaemia was suspected in 38 patients, with a delay of four (2-7) days after ECMO implantation, and confirmed in 14 patients, that is, a prevalence of 9%. Exploratory laparotomy was performed in six out of 14 patients, the others being too unstable to undergo surgery. All patients with mesenteric ischaemia died. Independent risk factors for developing mesenteric ischaemia were renal replacement therapy (odds ratio (OR) 4.5, 95% confidence interval (CI) 1.3-15.7, p=0.02) and onset of a second shock within the first five days (OR 7.8, 95% CI 1.5-41.3, p=0.02). Conversely, early initiation of enteral nutrition was negatively associated with mesenteric ischaemia (OR 0.15, 95% CI 0.03-0.69, p=0.02). Conclusions: Acute mesenteric ischaemia is a relatively frequent but dramatic complication among patients on V-A ECMO

Two stage hybrid approach for complex aortic coarctation repair

<p>Abstract</p> <p>Background</p> <p>Management of an adult patient with aortic coarctation and an associated cardiac pathology poses a great surgical challenge since there are no standard guidelines for the therapy of such complex pathology. Debate exists not only on which lesion should be corrected first, but also upon the type and timing of the procedure. Surgery can be one- or two-staged. Both of these strategies are accomplice with elevate morbidity and mortality.</p> <p>Case report</p> <p>In the face of such an extended surgical approach, balloon dilatation seems preferable for treatment of severe aortic coarctation.</p> <p>We present an adult male patient with aortic coarctation combined with ascending aorta aneurysm and concomitant aortic valve regurgitation. The aortic coarctation was corrected first, using percutaneous balloon dilatation; and in a second stage the aortic regurgitation and ascending aorta aneurysm was treated by Bentall procedure. The patients' postoperative period was uneventful. Three years after the operation he continues to do well.</p

Impact of Fractional Flow Reserve Derived from Coronary Computed Tomography Angiography on Heart Team Treatment Decision-Making in Patients with Multivessel Coronary Artery Disease: Insights from the SYNTAX III REVOLUTION Trial

Background: Fractional flow reserve (FFR) is a reliable tool for the functional assessment of coronary stenoses. FFR computed tomography (CT) derived (FFRCT) has shown to be accurate, but its clinical usefulness in patients with complex coronary artery disease remains to be investigated. The present study sought to determine the impact of FFRCT on heart team's treatment decision-making and selection of vessels for revascularization in patients with 3-vessel coronary artery disease. Methods: The trial was an international, multicenter study randomizing 2 heart teams to make a treatment decision between percutaneous coronary interventions and coronary artery bypass grafting using either coronary computed tomography angiography or conventional angiography. The heart teams received the FFRCT and had to make a treatment decision and planning integrating the functional component of the stenoses. Each heart team calculated the anatomic SYNTAX score, the noninvasive functional SYNTAX score and subsequently integrated the clinical information to compute the SYNTAX score III providing a treatment recommendation, that is, coronary artery bypass grafting, percutaneous coronary intervention, or equipoise coronary artery bypass grafting-percutaneous coronary intervention. The primary objective was to determine the proportion of patients in whom FFRCT changed the treatment decision and planning. Results: Overall, 223 patients were included. Coronary computed tomography angiography assessment was feasible in 99% of the patients and FFRCT analysis in 88%. FFRCT was available for 1030 lesions (mean FFRCT value 0.64\ub113). A treatment recommendation of coronary artery bypass grafting was made in 24% of the patients with coronary computed tomography angiography with FFRCT. The addition of FFRCT changed the treatment decision in 7% of the patients and modified selection of vessels for revascularization in 12%. With conventional angiography as reference, FFRCT assessment resulted in reclassification of 14% of patients from intermediate and high to low SYNTAX score tertile. Conclusions: In patients with 3-vessel coronary artery disease, a noninvasive physiology assessment using FFRCT changed heart team's treatment decision-making and procedural planning in one-fifth of the patients

Late cardiovascular complication after varicose vein endovascular ablation

Venous insufficiency of the lower limbs is one of the most common vascular disorders affecting millions of people worldwide. Endovascular techniques are considered by current guidelines as simple, safe and effective. Persistence or even migration of foreign bodies after varicose vein endovascular surgery is a rare and unfeared complication. Herein, we present the case of a 39-year-old woman who underwent endoluminal treatment of varicose veins &gt;2 years ago and she was admitted to our department for late cardiovascular complication caused by catheter or guidewire rupture and the dissemination of its fragments in the inferior vena cava, right heart chambers, liver and pulmonary arteries. A systematic verification of the length and integrity of the devices should be performed at the end of every endovascular procedure

Leiomyosarcoma of the right inferior pulmonary vein: 2 years survival with multimodality therapy

Primary leiomyosarcoma of the heart is an extremely rare and aggressive tumor. The authors report a case of a 29-year-old man with a leiomyosarcoma of the right inferior pulmonary vein who underwent surgery, chemotherapy, and radiotherapy. The patient experienced two local recurrences and he finally died 2 years after onset of symptoms because of multiple distal metastases

Surgery for delayed leaflet impingement after transcatheter closure of a paravalvular leak associated with an aortic pseudoaneurysm

Background: Paravalvular leak (PVL) is a recognized and challenging complication after surgical or transcatheter valve replacement. The transcatheter closure of PVL has become the first-line treatment in clinical practice when the procedure is not contraindicated. Transcatheter PVL closure rests on a complex procedure and complications still occur in approximately 9% of patients. Case Report: We describe the case of a delayed mechanical prosthetic leaflet impingement after transcatheter closure of a paravalvular leak associated with a Valsalva pseudoaneurysm that required an urgent surgery. Conclusion: Aorta–left ventricle communication could be a relative contraindication to be assessed on a case-by-case basis, but transcatheter closure does not preclude subsequent attempt for surgical repair and outcome

Influence of preoperative mitral valve function on postoperative patient outcome submitted to CABG with left ventricular dysfunction

Objectives: To assess the influence of preoperative mitral valve function on patient outcome after coronary revascularization in the presence of severely depressed left ventricular contractility (LVEF< 35%). Methods: Four hundred and twenty patients (mean age 61±11 years) submitted to CABG with LV impairment (mean EF 24±11%, range 12-34%) were retrospectively analysed. Off-pump CABG was performed in 58 patients, whereas the majority had conventional surgical revascularization. Associated mitral valve procedures were performed in 67 cases (repair in 50 patients, and replacement in 12, respectively). Patient population and postoperative outcome were evaluated according to the preoperative hemodynamic significance of mitral valve insufficiency (absent, trivial or mild in 340 patients, and moderate or severe in 98 cases, respectively). Surgical correction of mitral defect was performed in all patients with preoperative severe mitral regurge, and in the majority of cases (74%) with moderate degree of valve insufficiency. Follow-up data were analysed with Kaplan-Meier estimation to assess global and event-free survival. Results: There were 18 hospital deaths. Mean follow-up was 62±42 months. Overall survival was 82% at 2 years, 73% at 4 years, and 65% at 6 years. The preoperative presence of hemodynamically significant mitral insufficiency showed to have a limited impact on long-term global survival as compared to minor mitral dysfunction. Conversely, it negatively affected mid-and long-term recovery of functional capacity because of higher recurrence of heart failure episodes. Conclusions: Our retrospective study indicates that hemodynamically significant mitral regurgitation concomitant to coronary artery disease and LV impairment requires an aggressive surgical management not to enhance life expectancy, but rather to improve postoperative recovery of functional capacity and of quality of life
