Background and Aims: The purpose of this prospective randomized study was to compare the early and midterm outcomes of aortic valve replacement (AVR) through upper ministernotomy with conventional AVR through median sternotomy.Methods: One hundred patients undergoing elective AVR were randomized into two groups: the M group (upper ministernotomy group, n = 50) and the C group (conventional sternotomy group, n = 50). The operative data, major adverse outcomes, and postoperative variables were compared between the two groups of patients. A cross-sectional follow-up was performed 24.9 ± 5.8 months after surgery.Results: The aortic cross-clamp time and cardiopulmonary bypass time were significantly longer in the M group. Similar incidences of major cardiac, neurologic and renal complications were recorded in both groups. Two patients (4%) in the C group developed wound infections. The length of ICU stay was similar in both groups.The patients in the M group had a shorter hospital stay compared with the patients in the C group (7.6 ± 2 days vs 9.3 ± 4.8 days; P = 0.022). Follow-up revealed that the time period needed to reach full recovery was significantly shorter in the ministernotomy group (1.7 ± 1.2 months vs 2.8 ± 1.6 months; P = 0.001). Morbidity and mortality data did not differ between the two groups.Conclusions: There was no difference in the major outcomes between the patients who underwent upper ministernotomy and those who underwent full sternotomy.The benefits of the minimally invasive approach were the shorter hospital stay and significantly faster recovery of patients after discharge from the hospital.

Correcting chronic IMR with either repair or replacement produces a good mid-term survival rate (approximately 75%) for survivors in NYHA classes I and II. In our study, mortality rates for the MVP and MVR groups were similar, even though the repair group had a lower mean ejection fraction and a higher NYHA class before and after the operation. We therefore conclude that repair is superior to replacement in treating ischemic mitral insufficiency. A prospective randomized study is needed to better compare these 2 approaches.

The pedicled left internal thoracic artery graft is the mandatory conduit in coronary artery bypass surgery. A grossly emphysematous lung may sometimes present a significant problem for positioning of the pedicled left internal thoracic artery conduit. An inverted pedicled left internal thoracic artery graft (internal thoracic artery transected near its origin, thus supplied by retrograde flow from superior epigastric and musculophrenic arteries) might occasionally be the conduit of choice for those patients.

OBJECTIVES The German Registry of Acute Aortic Dissection Type A (GERAADA) on-line score calculator to predict 30-day mortality in patients undergoing surgery for acute type A aortic dissection (ATAAD) was recently launched. Using the European System for Cardiac Operative Risk Evaluation II (EuroSCORE II), it is also possible to predict operative mortality for the same type of surgery. The goal of our study was to validate the prediction accuracy of these 2 on-line risk prediction models. METHODS Prospectively collected data for EuroSCORE II risk factors as well as all data for GERAADA scoring were extracted from an institutional database for 147 patients who underwent surgery for ATAAD between April 2018 and April 2021. The discriminative power was assessed using area under the receiver operating characteristic curve. The calibration of the models was tested by the Hosmer–Lemeshow statistics and by using the observed-to-expected (O/E) mortality ratio with the 95% confidence interval. RESULTS The observed operative mortality was 14.3%. The mean predicted mortality rates for the GERAADA score and the EuroSCORE II were 15.6% and 10.6%, respectively. The EuroSCORE II discriminative power (area under the curve = 0.799) significantly outperformed the discriminatory power of the GERAADA score (area under the curve = 0.550). The Hosmer–Lemeshow statistics confirmed good calibration for both models (P-values of 0.49 and 0.29 for the GERAADA score and the EuroSCORE II, respectively). The O/E mortality ratio certified good calibration for both scores [GERAADA score (O/E ratio of 0.93, 95% confidence interval: 0.53–1.33); EuroSCORE II (O/E ratio of 1.35, 95% confidence interval: 0.77–1.93)]. CONCLUSIONS The EuroSCORE II has better discriminative power for predicting operative mortality in ATAAD surgery than the GERAADA score. Both scores confirmed good calibration ability.

The 44-year-old female was admitted to the hospital due to the severe pain in the right arm. Doppler ultrasonography revealed occlusion of the right brachial and right common carotid artery. Subsequently, computed tomography (CT) scan confirmed the occlusion of the right brachial and common carotid artery, and revealed pedunculated floating ascending aortic mass. The floating thrombus in ascending aorta is a rare and potentially very dangerous pathological condition. Although aetiology is still unclear, ascending aorta atherosclerosis and coagulation disorder are probably the most common reasons. Hypercoagulable state, high level of antiphospholipid antibody and factor VIII are closely relating with vascular thrombosis. Since the outbreak of the coronavirus-2019 (COVID-19) pandemic, increasing evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might produce hypercoagulable state with subsequent thrombosis and thromboembolism. The infection elevated the level of factor VIII in the blood and, consequently, increased the risk of adverse thrombotic and embolic events.Additionally, endothelial inflammation and injury mediated by coronavirus represent an additional risk factor.According to literature, this is the first case of the floating ascending aorta thrombus in the patient with SARS-CoV-2 infection. The thrombus' fragile structure and high blood velocity through the ascending aorta significantly increases cerebral and peripheral embolization incidence, with potentially fatal outcome. Due to frequent adverse events, urgent surgical extirpation is the best therapy option. We presented successfully surgically treated giant floating thrombus in the ascending aorta and aortic arch in a patient with recent SARS-CoV-2 infection with acute right arm ischemia due to embolic complication.
