RESUMO

A 58-year-old male patient presented with acute type A aortic dissection. Complete arch and ascending aorta replacement were performed using a Thoraflex Hybrid prosthesis. The left subclavian artery was ligated and the remaining supra-aortic trunks were reimplanted using the branches of the prosthesis. After an uneventful early postoperative period, sudden onset of hypotension and bradycardia occurred, with severe vasoplegia, requiring vasopressors. Ischemia of the upper left limb and compartment syndrome ensued, leading to left carotid subclavian bypass. After discontinuation of sedation, tetraplegia was noted due to spinal cord ischemia from C3 to C7.

RESUMO

A 67-year-old patient with history of heart transplantation was referred for symptomatic severe tricuspid regurgitation. Diagnostic workup showed chordal ruptures on the septal and anterior leaflets, most likely related to endomyocardial biopsies. Given the high surgical risk, the patient was treated percutaneously, with good results persisting at 3 months. (Level of Difficulty: Intermediate.).

RESUMO

OBJECTIVES: Anomalous aortic origin of a coronary artery (AAOCA) is the second leading cause of sudden death in children and young adults. The most threatening anatomy is an interarterial and an intramural course, both probably involved in ischaemic phenomena and sudden death. The treatment of interarterial AAOCA remains controversial. Most of the published studies describe the results of the unroofing technique. Our study aims to evaluate the results of a different surgical approach. METHODS: From 2005 to 2019, 61 patients were operated on for an interarterial AAOCA (median age 14.7 years). Forty patients had a right AAOCA, and 21 patients had a left AAOCA including 5 patients with intraseptal course. Seventy percent of patients were symptomatic. Five patients had an aborted sudden cardiac death. Two surgical techniques were used: an 'anatomical' repair for 35 patients (15 left and 22 right AAOCA) or a coronary translocation with creation of a neo-ostia in 19 patients (1 left and 18 right AAOCA). The 5 left AAOCA patients with an intra-septal course required a complete release of the coronary artery from the septum. RESULTS: There was no early or late postoperative death. Three patients had an acute postoperative ischaemic event. Two patients required immediate angioplasty and stenting: 1 patient (7 years) with a hypoplastic right AAOCA and 1 patient (66 years) for inadequate tailoring after septal release. The third patient required an immediate surgical revision (H-2) for left AAOCA thrombosis at the level of the pericardial patch with full myocardial recovery at discharge. During follow-up, 1 patient with right AAOCA translocation and chronic chest pain required subsequent stenting and finally a coronary artery bypass grafting 2 years after initial surgery. One patient who had an asymptomatic mild right coronary stenosis 1 year after anatomical repair was successfully treated by angioplasty alone. All patients but 1 who underwent coronary translocation are totally asymptomatic. All patients with anatomical repair or septal release are free from ischaemic symptoms. CONCLUSIONS: Anatomical repair might provide a better protective option for these patients. Unlike unroofing, it treats the entire intramural segment, relocates the ostium at the appropriate sinus level and corrects any acute take-off angle.
