The Stability

The aim of our study was to compare the results of the TTE (transthoracic echocardiography) with the results obtained by the ECG-gated 64 slices CT during the followup of patients with bicuspid aortic valve (BAV), after aortic valve replacement; in particular we evaluated the aortic root and the ascending aorta looking for a new algorithm in the followup of these patients. From January 1999 to December 2009 our attention was focused on 67 patients with isolated surgical substitution of aortic valve; after dismissal they were strictly observed. During the period between May and September 2010, these patients underwent their last evaluation, and clinical exams, ECG, TTE, and an ECG-gated-MDCT were performed. At followup TTE results showed an aortic root of 36.7±4 mm and an ascending aorta of 39.6±4.8 mm. ECG- gated CT showed an aortic root of 37.9±5.5 mm and an ascending aorta of 43.1±5.2. The comparison between preoperative and postoperative TTE shows a significant long-term dilatation of the ascending aorta while the aortic root diameter seems to be stable. ECG-gated CT confirms the stability of the aortic root diameter (38.2±5.3 mm versus 37.9±5.5  mm; <0.0001) and the increasing diameter value of the ascending aorta (40.2±3.9 mm versus 43.1±5.2 mm; P=0.0156). Due to the different findings between CT and TTE studies, ECG-gated CT should no longer be considered as a complementary exam in the followup of patients with BAV, but as a fundamental role since it is a real necessity.

Ross Procedure

Prosthesis choice for aortic valve replacement (AVR) in children is frequently compromised by unavailability of prostheses in very small sizes, the lack of prosthetic valve growth, and risks associated with long-term anticoagulation. The Ross procedure with pulmonary valve autograft offers several advantages for pediatric and adult patients. We describe our current Ross AVR technique including replacement of the ascending aorta with a prosthetic graft. The procedure shown in the video involves an adult-sized male with a bicuspid aortic valve, mixed aortic stenosis and insufficiency, and a dilated ascending aorta.

AbstractObjectivesThis study aimed to compare short- and long-term outcomes following various alternative access routes for transcatheter aortic valve replacement (TAVR).MethodsThirty-four studies with a pooled sample size of 30,986 records were selected by searching PubMed and Cochrane library databases from inception through 11th June 2021 for patients undergoing TAVR via 1 of 6 different access sites: Transfemoral (TF), Transaortic (TAO), Transapical (TA), Transcarotid (TC), Transaxillary/Subclavian (TSA), and Transcaval (TCV). Data extracted from these studies were used to conduct a frequentist network meta-analysis with a random-effects model using TF access as a reference group.ResultsCompared with TF, both TAO [RR 1.91, 95% CI (1.46–2.50)] and TA access [RR 2.12, 95%CI (1.84–2.46)] were associated with an increased risk of 30-day mortality. No significant difference was observed for stroke, myocardial infarction, major bleeding, conversion to open surgery, and major adverse cardiovascular or cerebrovascular events in the short-term (≤ 30 days). Major vascular complications were lower in TA [RR 0.43, (95% CI, 0.28-0.67)] and TC [RR 0.51, 95% CI (0.35-0.73)] access compared to TF. The 1-year mortality was higher in the TAO [RR of 1.35, (95% CI, 1.01–1.81)] and TA [RR 1.44, (95% CI, 1.14–1.81)] groups.ConclusionNon-thoracic alternative access site utilization for TAVR implantation (TC, TSA and TCV) is associated with similar outcomes to conventional TF access. Thoracic TAVR access (TAO and TA) is associated with increased short and long-term mortality.
