Retrograde ascending dissection can present as an early or a late complication after descending stent grafting because of aortic instability or disease progression and has usually been associated with descending dissection or intramural hematoma. It is a life-threatening complication that can be managed safely with early recognition and rapid delivery of open or hybrid repair.

Quadricuspid aortic valve dysfunction includes both regurgitation and stenosis; repair may be feasible in some patients with regurgitation, but most require replacement. Aortic root and ascending dilatation are frequent, and further studies are needed.

Aortitis continues to be a conundrum; however, good results are achievable with surgery. Intervention should be based on a clearer understanding of the histologic pattern and extent of disease, which helps in subsequent targeted disease management.

This randomized parallel controlled trial demonstrates that ultrasound-guided paravertebral block is safe and effective method for relieving post-cardiac surgery sternotomy pain compared with thoracic epidural analgesia but not superior to it.

Background Rivaroxaban has been recently introduced for the management of non-valvular intra-cardiac thrombosis with variable results. We aimed to compare the results of the off-label use of rivaroxaban versus warfarin in the management of patients with left ventricle (LV) thrombus. This research is a retrospective study conducted on 63 patients who had LV thrombus from January to December 2016. We compared patients treated with warfarin (n=35) to patients who had rivaroxaban (n=28), and study outcomes were time to thrombus resolution, bleeding, stroke, and mortality. Results The median duration of treatment was 9.5 (25th-75th percentiles: 6-32.5) months for rivaroxaban and 14 (3-41) months for warfarin. Thrombus resolution occurred in 24 patients in the warfarin group (68.6%) and 20 patients in the rivaroxaban group (71.4%). The median time to resolution in the warfarin group was 9 (4-20) months and 3 (2-11.5) months in the rivaroxaban group. Thrombus resolution was significantly faster in patients on rivaroxaban (p= 0.019). Predictors of thrombus resolution were thrombus surface area (HR: 1.21; CI 95% (1.0-1.46); p= .048) and the use of rivaroxaban (HR: 1.92; CI 95% (1.01-3.65); p= 0.048). There was no difference in stroke, bleeding, and mortality between both groups. Conclusion Rivaroxaban was as effective and safe as warfarin in managing patients with left ventricle thrombus. Larger randomized clinical trials are recommended to confirm our findings.

Objective. Noninfectious aortitis may occur in the context of a recognized systemic disease or as a topographically limited lesion without systemic features, which is called clinically isolated aortitis (CIA). This study was undertaken to better define and stress the limitations of this diagnostic category in a large population of patients in a single center dedicated to aortic diseases and to suggest recommendations for care.Methods. Records of patients undergoing thoracic aortic surgery (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012) at the Cleveland Clinic were reviewed to identify 196 patients with histopathologically proven aortitis. Clinical diagnoses (giant cell arteritis [GCA], Takayasu arteritis [TAK], CIA, or Other) were determined at the time of surgery. Clinical features, laboratory findings, and imaging results were recorded throughout the follow-up period. At least 6 months of follow-up data were available for 73 CIA patients.Results. The mean age of the patients at time of surgery was 65.6 years (range 15-88 years); 67% of patients were female, and 90.3% were white. At the time of surgery, 129 patients (65.8%) met criteria for CIA, 42 (21.4%) for GCA, 14 (7.1%) for TAK, and 11 (5.6%) met criteria for other systemic inflammatory diseases. During a mean followup period of 56.2 months, 19% of CIA patients developed new symptoms, 45% developed new radiographic vascular lesions, 40% underwent additional vascular surgery, and 12% died (n = 9). Eleven of 73 patients (15%) initially classified as having CIA developed features of a systemic disease, most often GCA.Conclusion. The majority of patients (66%) with histopathologically proven aortitis have CIA at the time of surgery. CIA patients infrequently report new symptoms over time, but new vascular lesions requiring surgery commonly occur. Serial follow-up including large vessel imaging is strongly advised for all aortitis patients.

BackgroundJunctional ectopic tachycardia is a serious arrhythmia that frequently occurs after tetralogy of Fallot repair. Arrhythmia prophylaxis is not feasible for all pediatric cardiac surgery patients and identification of high risk patients is required. The objectives of this study were to characterize patients with JET, identify its predictors and subsequent complications and the effect of various treatment strategies on the outcomes in selected TOF patients undergoing total repair before 2 years of age.MethodsFrom 2003 to 2017, 609 patients had Tetralogy of Fallot repair, 322 were included in our study. We excluded patients above 2 years and patients with preoperative arrhythmia. 29.8% of the patients (n = 96) had postoperative JET.ResultsJET patients were younger and had higher preoperative heart rate. Independent predictors of JET were younger age, higher preoperative heart rate, cyanotic spells, non-use of B-blockers and low Mg and Ca (p = 0.011, 0.018, 0.024, 0.001, 0.004 and 0.001; respectively). JET didn’t affect the duration of mechanical ventilation nor hospital stay (p = 0.12 and 0.2 respectively) but prolonged the ICU stay (p = 0.011). JET resolved in 39.5% (n = 38) of patients responding to conventional measures. Amiodarone was used in 31.25% (n = 30) of patients and its use was associated with longer ICU stay (p = 0.017). Ventricular pacing was required in 4 patients (5.2%). Median duration of JET was 30.5 h and 5 patients had recurrent JET episode. Timing of JET onset didn’t affect ICU (p = 0.43) or hospital stay (p = 0.14) however, long duration of JET increased ICU and hospital stay (p = 0.02 and 0.009; respectively).ConclusionJET increases ICU stay after TOF repair. Preoperative B-blockers significantly reduced JET. Patients with preoperative risk factors could benefit from preoperative arrhythmia prophylaxis and aggressive management of postoperative electrolyte disturbance is essential.
