Background In the absence of a standardized safe surgical reentry strategy for high-risk patients with large or anterior postoperative aortic false aneurysm (PAFA), we aimed to describe an effective ...and safe approach for such patients. Methods We prospectively analyzed patients treated for PAFA between 2006 and 2015. According to the preoperative computed tomography scan examination, patients were divided into two groups according to the anatomy and extension of PAFA: in group A, high-risk PAFA (diameter ≥3 cm) developed in the anterior mediastinum; in group B, low-risk PAFA (diameter <3 cm) was situated posteriorly. For group A, a safe surgical strategy, including continuous cerebral, visceral, and coronary perfusion was adopted before resternotomy; group B patients underwent conventional surgery. Results We treated 27 patients (safe reentry, n = 13; standard approach, n = 14). Mean age was 60 years (range, 29 to 80); 17 patients were male. Mean interval between the first operation and the last procedure was 4.3 years. Overall 30-day mortality rate was 7.4% (1 patient in each group). No aorta-related mortality was observed at 1 and 5 years in either group. The Kaplan-Meier overall survival estimates at 1 and 5 years were, respectively, 92.3% ± 7.4% and 73.4% ± 13.4% in group A, and 92.9% ± 6.9% and 72.2% ± 13.9% in group B (log rank test, p = 0.830). Freedom from reoperation for recurrent aortic disease was 100% at 1 year and 88% at 5 years. Conclusions The safe reentry technique with continuous cerebral, visceral, and coronary perfusion for high-risk patients resulted in early and midterm outcomes similar to those observed for low-risk patients undergoing conventional surgery.
We report the first known cases of successful implantation of the Edwards INTUITY (Edwards Lifesciences LLC, Irvine, CA) rapid-deployment valve in 3 patients with aortic stenosis presenting under ...emergency cardiogenic shock. At the 6-month follow-up, the 3 patients showed improved left ventricular function and improved functional capacity.
Abstract A 43-year-old man with systemic sclerosis and chest pain had negative T waves in precordial ECG leads. The echocardiogram showed a large left ventricular apical accessory chamber. The ...coronaries were normal. Cardiac Magnetic Resonance (MRI) showed a large fibrotic aneurysm, and a small patch of midwall late enhancement in the septum. The aneurysm was surgically removed. At the 8 months follow-up, cardiac MRI showed the appearance of a new nodular lesion in the anterior wall, causing a localized wall motion abnormality. Myocardial involvement in patients with systemic sclerosis can be severe, and cardiac MRI evaluation is fundamental.

Abstract Advanced chronic kidney disease (CKD) is associated with poor outcomes in patients undergoing surgical aortic valve replacement while its prognostic role in transcatheter aortic valve ...implantation (TAVI) remains unclear. This study aimed to investigate outcomes in patients with advanced CKD undergoing TAVI. 1904 consecutive patients undergoing balloon-expandable TAVI in 33 centers between 2007-2012 were enrolled in the I talian T ranscatheter Balloon- E xpandable Valve Implantation R egistry (ITER). Advanced CKD was defined according to estimated glomerular filtration rate (eGFR): 15-29 mL/min/1.73m2 stage 4 (S4), <15 mL/min/1.73m2 stage 5 (S5). Edwards Sapien or Sapien-XT prosthesis were used. Primary end-point was all-cause mortality during follow-up. Secondary end-points were 30-days and FU major-adverse-cardiac-events (MACE), defined with VARC-2 criteria. 421 patients were staged S5 (n=74) or S4 (n=347). S5 patients were younger, had more frequently porcelain aorta and lower incidence of previous stroke. Peri-procedural and 30-days outcomes were similar in S5 and S4 patients. During a 670 (±466) days of FU, S5 patients suffered higher mortality rates (69% vs. 39%, p<0.01) and cardiac death (19% vs. 9%, p=0.02) compared to S4. Male sex (HR 1.6, 95%CI 1.2-2.2), LVEF<30% (HR 2.3, 95% CI: 1.3-4), atrial fibrillation (HR 1.4, 95%CI:1.0-1.9) and S5 CKD (HR 1.5, 95%CI: 1.0-2.1) were independent predictors of death. In conclusion, TAVI in pre-dialytic or dialytic patients (i.e. S5) is independently associated with poor outcomes with more than double risk of death compared to patients with stage 4 renal function. Conversely, in severe CKD (i.e. S4) a rigorous risk stratification is required to avoid the risk of futility risk.
