Objective: Giant cell arteritis (GCA) may present as proximal aortic pathology requiring surgical intervention. We present our experience with surgical management of GCA in patients presenting with proximal aortic disease.
Methods: From January 1993 to May 2020, 184 adult patients were diagnosed with GCA on histopathology after undergoing cardiac surgery.
Objective: There are limited data on the outcome of routine cardiac operations in patients with cardiac amyloidosis. This study studied the impact of amyloidosis on early and late results of cardiac operations.
Methods: This was a retrospective, propensity-matched, case-control study of patients with cardiac amyloidosis undergoing cardiac surgery.
Article Synopsis
- The study aimed to assess the prognostic value of right ventricle (RV) function and its coupling to pulmonary artery pressure in patients with tricuspid regurgitation (TR) to improve risk evaluation beyond an established clinical score.
- Researchers analyzed data from 417 patients with moderate TR and developed a new risk score by integrating RV function measures, finding significant correlations between these parameters and patient mortality during a median follow-up of nearly 4 years.
- Results showed that many patients initially categorized as low- or intermediate-risk were reclassified to higher risk when RV function metrics were included, indicating that incorporating these echocardiographic measures enhances mortality predictions in TR patients.
Objective: To compare target artery (TA) outcomes after fenestrated or branched endovascular aortic repair (FB-EVAR) versus open surgical repair (OSR) of thoracoabdominal aortic aneurysms (TAAAs).
Background: Few studies have compared TA outcomes after endovascular incorporation and open reconstruction.
Methods: Among consecutive patients who underwent elective OSR or FB-EVAR of TAAAs (2008-2020), we reviewed those who had postoperative imaging studies evaluating TA.
Right Ventricular Perforation by Fractured Sternal Wires: A Narrative Review.
Braz J Cardiovasc Surg
October 2024
Article Synopsis
- Migration of a fragmented sternal wire is a rare complication after cardiovascular surgery, with clinical symptoms ranging from being asymptomatic to severe hemodynamic instability.* -
- A retrospective review revealed 13 cases of this issue, primarily affecting older men (median age 64), with nearly half experiencing hemorrhagic shock, and most cases presenting either shortly after surgery or years later.* -
- Identifying this complication often involves CT scans, but successful management requires careful attention to the patient's specific situation following diagnosis.*
