    Abstract Small lymphocytic lymphoma (SLL) is rarely associated with thoracic aortic aneurysms. Aneurysm of the ascending aorta associated with SLL has never been reported before. We describe the case of an asymptomatic 68-year-old woman who presented with a 5.5-cm aneurysm of the ascending aorta and no prior history of hematological disorders. Following excision and repair, the surgical specimen showed infiltration of the aortic wall by lymphocytes, expressing markers consistent with SLL. While symptomatic SLL carries a poor prognosis, risk stratification tools are applied to guide management strategies in asymptomatic patients.

    Abstract Surgical management of a calcified homograft with associated severe aortic insufficiency is challenging because of the technical difficulty in occluding the aorta. We present a hybrid method of homograft occlusion during the cooling phase of a homograft replacement procedure that required the use of circulatory arrest.

    Abstract Background: Use of recombinant activated factor VII (rFVIIa) to achieve hemostasis during cardiac surgery continues to be debated, as support for its efficacy and safety has not been consistent. We examined our experience with rFVIIa for achieving hemostasis in high-risk patients undergoing complex ascending aortic surgery.
    Methods: We reviewed patients who underwent complex ascending aortic surgery performed by a single surgeon (C. K. R.) from August 2014 to February 2019. Outcomes of patients who received rFVIIa were compared with those who did not.
    Results: Of 59 consecutive patients, 20 patients (33.9%) received rFVIIa, whereas 39 (66.1%) did not. Median dose was 45.4 mcg/kg. rFVIIa was administered intraoperatively to 95% of patients who received it. Most patients underwent combined aortic valve, ascending aorta, and aortic arch surgery (80.0% vs. 64.1%, p = .52). Patients receiving rFVIIa had longer mean cross clamp times (212 vs. 173 min, p = .03) and received a greater median number of intraoperative blood products (18.5 vs. 12.0, p < .001). The number of patients who needed postoperative products (75.0% vs. 60.5%, p = .39), the median number of blood products transfused postoperatively (2 vs. 2, p = .40), and chest tube output (1138 vs. 805 ml, p = .17) were similar between groups. In-hospital mortality was similar between groups (10.0% vs. 10.3%, p = 1.00). Incidences of postoperative stroke (10.0% vs. 13.5%, p = 1.00) and thromboembolic events (10.0% vs. 13.5%, p = 1.00) were similar.
    Conclusions: Administration of rFVIIa intraoperatively for refractory bleeding during complex ascending aortic surgery provided hemostasis without greater in-hospital mortality or a higher risk of stroke and thromboembolic events.

    Abstract Functional mediastinal paragangliomas (PGs) are rare, catecholamine-secreting tumours. Surgical resection is the preferred treatment, but it can be complicated by catecholamine-related symptoms, involvement of cardiac structures and/or tumour supply from major blood vessels. We report a case of a man in his 30s with a subcarinal functional PG complicated by all three factors. The PG had arterial supplies from the right coronary and bronchial arteries, with mass effect on the left atrium. Given the high risk of intraoperative bleeding, catecholamine surges and injury to right coronary artery, we attempted a minimally invasive strategy that incorporates best practices from the few published cases on functional PGs. We show that a multidisciplinary approach involving alpha/beta blockade, preoperative embolisation of tumour blood supply, robotic-assisted tumour mobilisation and, if needed, open resection with cardiopulmonary bypass can be a safe strategy in the treatment of functional mediastinal paragangliomas adherent to cardiac structures.

    Abstract Aberrant right subclavian artery is the most common brachiocephalic artery congenital abnormality and may result in dysphagia from external compression by the aberrant artery on the esophagus. Repair of this anatomic variant can be performed by both open and hybrid endovascular techniques. This case illustrates a complication of a hybrid repair resulting in proximal migration of a vascular occlusion plug, presenting as recurrent dysphagia and need for open surgical extraction of the plug.
