Myocardial damage from external cardiac massage can occur with either manual massage or with an automatic external device. We report the case of a patient with an aortic valve bioprosthesis undergoing advanced resuscitation with an automated external device for out-of-hospital-cardiac arrest, in whom the prolonged compressions caused an aortic root dissection.

Aim: Cardiac surgery patients have different resuscitative needs than other patients who experience in-hospital cardiac arrest, this was addressed in the guidelines. However, it is unknown how widely the guidelines are practiced, or a training protocol is followed in different cardiac surgery units in Egypt. Methods: A 21-question survey is created and included: Participants demographics, Prevalence of cardiac arrest, Cardiac arrest protocol, Emergency resternotomy technique, Training protocols. Survey was disseminated through social media messaging platforms during the period between November 2020 and January 2021. Results: 95 responses were from 11 centres across Egypt. 68.5% of the respondents were surgeons, 76.8% of participants were junior surgeons. For patients who go into VF after cardiac surgery, respondents would attempt a median of 3 shocks with only 24.2% commencing defibrillation shocks before external cardiac massage, while the majority initiating CPR immediately and performing emergency resternotomy in a median time of 10 mins. 56.8% would give 1 mg of adrenaline as soon the cardiac arrest was established. If a surgeon was not available, only 36.8% of respondents would allow any trained personnel to perform the emergency resternotomy. Only 9.5% practice regularly on emergency sternotomies. 75% think tailored training is important and staff should be oriented about it in the future. Conclusion: An action plan is required to improve the awareness of the junior surgeons with the Cardiac Advanced Life Support Protocol.

Introduction: Surgical aortic valve replacement (SAVR) in a small aortic root is still challenging with regard to the surgical technique and prosthesis size selection, which often causes patient-prosthesis mismatch (PPM). On the other hand, because a prosthetic valve of transcatheter aortic valve replacement (TAVR) is tightly implanted inside a native valve, larger effective orifice area (EOA) may be gained. The aim of this study is to prove that hemodynamic performance after TAVR is superior to that after SAVR. Methods: 160 patients, who underwent SAVR (n=36; age 75.1±5.6 years) and TAVR (n=124; age 82.4±6.8 years) for aortic valve stenosis, were enrolled. Preoperative ECG-gated multi-slice CT (MSCT) and echocardiography immediately before a discharge were performed in all patients. PPM was defined as the effective orifice area index ≤0.85cm2/m2 and we compared and examined hemodynamic performance after TAVR and SAVR. Results: Although the mean body size was significantly smaller (p<.05) in TAVR than that in SAVR (1.44±0.15 vs 1.51±0.20 m2), there were no significant differences in the diameters of annulus (23.2±1.6 vs 23.3±2.8 mm), valsalva sinus (29.8±2.6 vs 29.9±4.4 mm), and ST junction (25.2±2.8 vs 24.8±3.5 mm) on preoperative MSCT findings. Postoperative echocardiography revealed significantly less Vmax (2.2±0.4 vs 2.5±0.5 m/s, p<.0001), less mean pressure gradient (10.1±3.6 vs 14.5±5.0 mmHg, p<.0001), and larger EOA (1.62±0.29 vs 1.45±0.36 cm2, p<.005) in TAVR compared to SAVR, respectively. Consequently, PPM was more frequently in SAVR compared to TAVR (33.3 vs 8.9%; p<.0007). In multivariate analysis in SAVR identified small ST junction with only predictive factor of PPM (odds ratio [OR], 2.08; 95% CI, 1.23-4.36; p<.005; area under the receiver-operating characteristic curve [AUC], 0.84). On the other hand, regarding TAVR, large BSA was only predictive factor of PPM (p<.05). Conclusions: The hemodynamic performance of transcatheter prosthetic valve is superior to that of surgical prosthetic valve in a patient with small aortic root, in particular, small ST junction. TAVR should be considered in patients with anticipated PPM if the surgical risk is similar to TAVR.

ObjectOur goal was to assess the implant depth of a Venus-A prosthesis during transcatheter aortic valve replacement (TAVR) when the areas of eccentric calcification were distributed in different sections of the aortic valve.MethodsA total of 53 patients with eccentric calcification of the aortic valve who underwent TAVR with a Venus-A prosthesis from January 2018 to November 2019 were retrospectively analyzed. The patients were divided into three groups (A, B, and C) according to the location of the eccentric calcification, which was determined by preprocedural computerized tomography angiography (CTA) images. The prosthesis release process and position were evaluated by contrast aortography during TAVR, and the differences in valve implant depths were compared among the three groups. The effects of different aortic root structures and procedural strategies on prosthesis implant depth were analyzed.ResultsEleven patients had eccentric calcification in region A; 19 patients, in region B; and 23 patients, in region C. The patients with eccentric calcification in region B had a higher risk of prosthesis migration (10.5% upward and 21.1% downward), and the position of the prosthesis after TAVR in group B was the deepest among the three groups. When eccentric calcification was located in region A or C, the prosthesis was released at the standard position with more stability, and the location of the prosthesis was less deep after TAVR (region A: 4.12 ± 3.4 mm; region B: 10.2 ± 5.3 mm; region C: 8.4 ± 4.0 mm; region A vs. region B, P = 0.0004; region C vs. region B; and P = 0.0360). In addition, the left ventricular outflow tract (LVOT) (P = 0.0213) and aortic root angulation (P = 0.0263) also had a significant effect on implant depth in the aortic root structure of the patients. The prosthesis size was 28.3 ± 2.4 in the deep implant group and 26.4 ± 2.0 in the appropriate implant group (P = 0.0068).ConclusionThe implant depth of the Venus-A prosthesis is closely related to the distribution of eccentric calcification in the aortic valve during TAVR. Surgeons should adjust the surgical strategy according to aortic root morphology to prevent prosthesis migration.

Aortic valve replacement is the second most common cardiac surgery procedure. Prosthesis-patient size mismatch can increase the incidence of adverse events postoperatively, it also leads to increased left ventricular load. Some studies describe the higher mortality in this group of patients. It is also proved that patients with severe aortic stenosis usually have impaired platelet aggregation and low von Willebrand factor causing bleeding disorders. We report a case of successful aortic valve replacement and aortic root enlargement (Nicks technique) combined with coronary artery bypass grafting (left internal mammary artery to the left anterior descending artery) and left atrial appendage resection in 73-y.o. obese female patient. Postoperative course was uneventful.
