A rare case of life-threatening spontaneous psoas hematoma following cardiac surgery

Spontaneous psoas haematomas are uncommon, even in patients with coagulopathies on anticoagulation therapy. We report a unique case of a life-threatening spontaneous psoas haematoma in a patient during the immediate post-operative period following open heart surgery, despite a normal pre- and post-operative coagulation profil

Case report : Right atrial mass arising from the eustachian valve

A mass in the right atrium (RA) is an unusual finding that warrants further investigation. We report the case of a 72-year-old male patient who underwent a Bentall operation with a biological composite graft and closure of patent foramen ovale 18 months prior to his presentation with an incidental new RA mass during follow-up echocardiography. Transesophageal echocardiography and thoracic CT angiography confirmed a right atrial mass attached to the Eustachian valve and additionally revealed a non-occlusive pulmonary embolism in the inferior lobar artery of the left lung. Despite 2 months of anticoagulation treatment, the size of the mass did not decrease. Further MRI imaging showed a central mass enhancement which raised concerns about a tumoral lesion. Following a discussion with the local Heart Team, management with surgical treatment was decided. The intraoperative findings revealed a 2.5 cm × 2.1 cm mass arising from the Eustachian valve and a non-diagnosed Chiari network in the RA. Both were resected and sent for a frozen section procedure which excluded a malignancy. The final histopathological analysis described fibrotic tissues compatible with an organized thrombus. The patient was discharged on postoperative day 7 without any complications. Although imaging studies are useful for the initial and differential diagnosis of RA masses, it is not always possible to get the final diagnosis without surgery. In case of a suspicion of a potentially malignant pathology, surgical exploration and resection are necessary

Mitral Annuloplasty Using A Biodegradable Annuloplasty Ring

With the advent of several valve repair techniques, mitral valve repair is now preferred over mitral valve replacement as the treatment of choice for several mitral pathologic conditions. Because annular dilation is a vital component in most cases of chronic mitral regurgitation (MR), annular support is necessary to provide adequate repair and optimum long-term results.1 Annular reinforcement permits shrinking of the dilated annulus, allowing adequate coaptation of the valve leaflets, thereby preventing recurrent dilation

External Saphenous Vein Support Mesh Does Not Interfere With Transit-Time Flow Measurement on Venous Coronary Bypass Conduit: Clinical Confirmation

A 65-year-old patient underwent double coronary artery bypass grafting using the left internal thoracic artery on the left anterior descending coronary artery and nitinol alloy mesh [external Saphenous Vein Support (eSVS)]-covered saphenous vein graft to the right posterior descending coronary artery. Transit-time flow measurements (TTFMs) were obtained on meshed and bare parts of the vein graft. There was no difference in TTFM parameters (flow, pulsatility index, and diastolic fraction values) obtained from the eSVS mesh-covered and the uncovered parts of the venous graft. This observation confirms that eSVS mesh does not interfere with TTFM on venous coronary bypass conduits

Effective Apixaban removal using hemoadsorption during emergent open-heart surgery : a case report and narrative literature review

Background: The management of hemostasis in patients medicated with apixaban (Eliquis) undergoing emergency cardiac surgery is exceedingly difficult. The body's natural elimination pathways for apixaban prove ineffective in emergency situations, and the impact of hemodialysis is limited. The application of Cytosorb®may attenuate the concentration of apixaban, thereby facilitating the stabilization of these patients. Case presentation: An 84-year-old man treated with apixaban, underwent emergency ascending aorta replacement surgery due to an acute type A aortic dissection. To address the challenges induced by apixaban, we integrated Cytosorb®cartridge into the Cardiopulmonary bypass circuit. There was a 63.7% decrease in perioperative apixaban-specific anti-factor Xa activity. The patient's postoperative course was favourable. Conclusion: Hemoadsorption with Cytosorb®may offers a safe and feasible approach for reducing apixaban concentration in emergency cardiac surgery, thereby mitigating the risk of hemorrhagic complications.</p

Homografts and xenografts for right ventricular outflow tract reconstruction: long-term results

BACKGROUND: Cryopreserved valved homografts are the most commonly used conduit for right ventricular outflow tract reconstruction in children. Early need for reoperation owing to accelerated fibrocalcification has been observed in neonates and children younger than 3 years. A valved bovine jugular vein conduit, Contegra, has shown good early results, without early accelerated fibrocalcification even in the very young patients. This study determined long-term results of homografts and midterm results of Contegra grafts, with special emphasis on reoperation rate. METHODS: Between January 1993 and March 2009, 205 children received cryopreserved aortic homografts (n = 120, 66 blood group compatible [iso] and 54 non-blood group compatible [non-iso]) or Contegra grafts (n = 85, introduced in January 2000) for right ventricular outflow tract reconstruction and were followed from 6 months to 16 years. Primary diagnosis was tetralogy of Fallot (47%), pulmonary stenosis and atresia (19%), and truncus arteriosus (11%). Conduit dysfunction and need for reoperation were evaluated during follow-up. RESULTS: There were no hospital deaths in the homograft group and 2 deaths of conduit-unrelated cause in the Contegra group, During follow-up 3 patients died in the homograft group from graft-unrelated cause, and none died in the Contegra group. Early reoperation as a result of fibrocalcification and stenosis (within 2 years) was required in 1 Contegra graft patient (1.1%) compared with 8 patients in the homograft group (6.7%), all non-iso. Freedom from reoperation for Contegra grafts was 89.0% at 9 years, compared with non-iso homografts 63.0% and iso-homografts 85.7%. CONCLUSIONS: Non-blood group-compatible homografts have a significantly higher early reoperation rate than blood group-compatible homografts. Contegra grafts have a very low early reoperation rate and could therefore be used in neonates and children younger than 3 years of age, if a blood group-compatible homograft cannot be found. In children older than 3 years blood group compatibility is less important

Comparison of Perioperative and Postoperative Outcomes Among 3 Left Atrial Incisions : Conventional Direct, Transseptal, and Superior Septal Left Atriotomy

Background: Achieving optimal exposure of the mitral valve during surgical intervention poses a significant challenge. This study aimed to compare perioperative and postoperative outcomes associated with 3 left atriotomy techniques in mitral valve surgery-the conventional direct, transseptal, and superior septal approaches-and assess differences during the surgical procedure and the postoperative period. Methods: Inclusion criteria were patients undergoing mitral valve surgery from January 2010 to December 2020, categorized into 3 cohorts: group 1 (conventional direct; n = 115), group 2 (transseptal; n = 33), and group 3 (superior septal; n = 59). To bolster sample size, the study included patients undergoing mitral valve surgery independently or in conjunction with other procedures (eg, coronary artery bypass grafting, aortictricuspid surgery, or maze procedure). Results: No substantial variance was observed in the etiology of mitral valve disease across groups, except for a higher incidence of endocarditis in group 3 (P = .01). Group 1 exhibited a higher frequency of elective surgeries and isolated mitral valve procedures (P = .008), along with reduced aortic clamping and cardiopulmonary bypass durations (P = .002). Conversely, group 3 patients represented a greater proportion of emergency procedures (P = .01) and prolonged intensive care unit and hospital stays (P = .001). No significant disparities were detected in terms of permanent pacemaker implantation, postoperative complications, or mortality among the groups. Conclusion: Mitral valve operations that employed these 3 atriotomy techniques demonstrated a safe profile. The conventional direct approach notably reduced aortic clamping and cardiopulmonary bypass durations. The superior septal method was primarily employed for acute pathologies, with no significant escalation in postoperative arrhythmias or permanent pacemaker implantation, although these patients had prolonged intensive care unit and hospital stays. These outcomes may be linked to the underlying pathology and nature of the surgical intervention rather than the incision method itself.</p

External stenting of saphenous vein bypass grafts does not affect intraoperative transit-time flow measurement

Saphenous vein grafts (SVG) are the most commonly used conduits for coronary artery bypass operations (CABG), despite their sub-optimal long-term patency. External stenting of SVG (eSVS® mesh) was recently proposed to improve their long term patency. Transit time flow measurement (TTFM) is a well described method for intraoperative quality control for CABG
