Case of left ventricular thrombus managed with thrombectomy with left ventricular reconstruction in a patient who had coronavirus disease 2019 infection
Intracardiac thrombus is relatively rare in patients with coronavirus disease 2019 (COVID-19). However, if it occurs, thrombotic complications are likely to develop. In this case, we performed a successful thr… Read More

Journey Toward Improved Long-Term Outcomes After Norwood-Sano Procedure: Focus on the Aortic Arch Reconstruction
World J Pediatr Congenit Heart Surg. 2022 Sep;13(5):581-587. doi: 10.1177/21501351221116766.
ABSTRACT
The disadvantage of right ventricle-to-pulmonary artery (RV-PA) shunt is the need for more unplanned interventions to address stenosis in the shunt or branch pulmonary arteries, as compared to the modified Blalock-Taussig shunt group. Ring-enforced RV-PA PTFE conduit and dunk technique minimized these complications and right ventricle (RV) damage. Aortic arch obstruction increases afterload and leads to ventricular dysfunction and tricuspid regurgitation; therefore, most surgeons prefer to use homograft, autologous pericardium, or bovine pericardium to reconstruct the neoaorta. Artificial materials decrease the elastic properties, increase wall stiffness, and decrease the distensibility of the aorta; and as a result, RV function gradually deteriorates. This inelastic reconstructed aorta may be one of the reasons why long-term outcomes after the Fontan procedure are worse in hypoplastic left heart syndrome (HLHS) patients, in comparison to non-HLHS. Reconstruction of the neoaorta without any patch materials, or at least techniques that largely minimize the use of non-autologous materials, will offer a further refinement of our ability to optimize ventriculoarterial coupling and thereby long-term RV function.

The use of lyophilized bovine pericardium (Tutopatch®) in the management of third nerve palsy following prior conventional strabismus surgery – a case series
Strabismus. 2022 Dec;30(4):171-182. doi: 10.1080/09273972.2022.2123943. Epub 2022 Sep 30.
ABSTRACT
To study the secondary management of strabismus due to third nerve palsy using bovine pericardium (Tutopatch®) when previous conventional surgical therapy had failed. Review of our clinic records of selected patients with third nerve palsy, in whom residual deviation had been managed using Tutopatch® after previous surgical correction. The squint angle was measured preoperatively, and at 1 day, 3 months, and if possible 6 months postoperatively. Nine patients were enrolled in this study. One patient had mainly residual vertical deviation and was corrected with tendon elongation of the contralateral superior rectus. Three patients were operated on with tendon elongation of the lateral rectus muscle with or without medial rectus muscle resection and/or advancement (Group 1). Lateral rectus splitting after tendon elongation in addition to the resection and/or advancement of the medial rectus was performed in five patients with complete third nerve palsy (Group 2). In Group 1, the preoperative median squint angle was -20° (range -17° to -25°), which improved postoperatively to -4.5° (range -12° to +3°). In Group 2, the preoperative horizontal and vertical median squint angles were -27° (range -20° to -40°) and 0.5° (range 0° and 20°), respectively. Postoperatively, they had improved to -12.5° (range-2° to -25°), and 1.5° (range 0° to 7°), respectively. Two patients of Group 2 were re-operated due to residual exotropia. No postoperative complications were observed in any patient. In this small series several complex re-do situations of patients with third nerve palsy were evaluated in which Tutopatch® markedly improved outcomes after an initially ineffective surgical management. For better evaluation of its usefulness a study with more patients is recommended.
