An 83-year-old woman presented with a new onset of dyspnea and dysphonia. Physical examination revealed no abnormalities. Computerized tomography, bidimensional echocardiography, and cardiac magnetic resonance confirmed the presence of a cardiac mass in the left atrium. Surgical resection was uneventful and showed the origin of the mass in the ostium of the left inferior pulmonary vein. Histological evaluation revealed undifferentiated pleomorphic sarcoma with myxoid features. This case highlights the importance of considering cardiac neoplasms as a rare differential diagnosis, including rare and misleading clinical presentations.

Vasoplegic syndrome is associated with high mortality. Methylene blue (MB) is a guanylate cyclase inhibitor that ameliorates this re-distributive type of shock. This study aims to investigate the outcome in patients who received MB early postoperatively. 2753 patients who underwent cardiac surgery utilizing cardiopulmonary bypass at our institution in a time interval of two years were identified. The incidence of vasoplegic syndrome was 7.2% (n = 200). Pharmacy records identified 84 patients (group 1, MB group) who received methylene blue and 116 patients (group 2, Control group) who didn't receive the drug. This single-center retrospective cohort study's primary outcome was in-hospital mortality. Secondary outcomes were postoperative hemodialysis, serum lactate levels at 24 h postoperatively, and intensive care unit stay length in days. MB patients have a shorter ICU stay as compared to the control group (9 ± 8 days vs. 16 ± 6.9; p-value <.001). In the control group, postoperative hemodialysis was higher (20% in the MB group and 40% in the control group; p-value <.05). At 24 h post-op, the methylene blue group had reduced serum lactate levels (1.8 ± 1.2 vs. 4 ± 1.8 in the control group; p-value <.001). The methylene blue group had a decreased 24-hour norepinephrine dose (1.5 ± 1.2 vs. 2.8 ± 2 in the control group; p-value <.05). In-hospital mortality was not significantly different between the two groups (38% in the MB group vs. 43% in the control group). Early postoperative administration of methylene blue in patients with vasoplegic syndrome shortens intensive care unit stay and contributes to less end-organ damage.

Background: The optimal management strategy for acute aortic type A dissection remains controversial. Whether a limited primary (index) repair would increase the need for late aortic reintervention is still an open debate. Methods: A total of 393 consecutive adult patients with acute type A aortic dissection who underwent cardiac surgery were analyzed. Our research hypothesis was whether limited aortic index repair (i.e., isolated aorta ascending replacement without an open distal anastomosis with and without a concomitant aortic valve replacement, including hemiarch replacement procedure) is associated with a higher incidence of late aortic reoperation compared with extended repair (i.e., any other surgical procedure that goes beyond that limited approach). Results: Type of the initial repair had no statically significant relationship with in-hospital mortality with a P-value of 0.12, however in multivariable analysis, cross-clamp time had a statistically significant relation with mortality (P = 0.4). From the patients who survived until discharge (N = 311), 40 patients needed a reoperation on the aorta; the mean interval until reoperation was 4.5 years. The relationship between the type of the initial repair and the need for reoperation didn’t reach a statically significant value (P = 0.9). In-hospitable mortality after the second operation was 10% (N = 4). Conclusion: We reached two conclusions. 1) An extended prophylactic repair in the initial operation of an acute type A aortic dissection might not lead to a lower incidence of reoperations on the aorta and could increase in-hospital mortality by increasing cross-clamp time, and 2) Reoperation on the aorta could be done safely with acceptable mortality outcomes.

Dislodgement of a coronary stent-balloon catheter during percutaneous coronary intervention (PCI) is rare but is a life-threatening complication. A 57- year-old male presented with a non-ST elevation myocardial infarction (NSTEMI). Coronary angiography revealed total thrombotic occlusion of the Right coronary artery (RCA). Following the balloon dilatation of the RCA and while trying to retrieve the balloon catheter, the balloon was dislodged from the catheter shaft and entrapped in the coronary vessel. Under cardiopulmonary bypass, with antegrade cardioplegic arrest, the balloon was extracted through a coronary arteriotomy. Right coronary revascularization was done with reversed saphenous vein graft (SVG). Given the variety of equipment that can be retained in the coronary artery and the multitude of mechanisms by which it may be entrapped, there are no straightforward techniques applicable to all situations. Specific guidelines or recommendations on properly managing these potentially life-threatening complications do not exist. However, the most crucial issue in the management of these cases is the hemodynamic status of the patient as well as the coronary flow in the vessel with entrapped device or stent. In our case, the RCA was retrogradely perfused from the left coronary artery, which provided time to transfer the patient to cardiovascular surgical backup.

Background: Especially in the first 3 months after cardiac surgery, patients are at transient risk of sudden cardiac death (SCD). To close the gap between hospital discharge and the final implantable cardioverter‐defibrillator (ICD) decision, guidelines recommend temporarily using a wearable cardioverter‐defibrillator (WCD) to protect these patients from SCD. We investigated real‐life data on the safety, effectiveness, and compliance of the WCD in this population.Methods: Data for analysis were collected via the Zoll Patient Management Network (ZPM) from patients who underwent cardiac surgery and who were discharged with a WCD between 2018 and 2021 at the Cardiac Surgery Center of the University of Erlangen in Germany.Results: The majority of the 55 patients were male (90.9%) and underwent a coronary artery bypass graft (80.0%). The number of patients with left ventricular ejection fraction (LVEF) >35% increased from 9.1% at the beginning of WCD use to 58.2% at the end of WCD use. Six ventricular tachycardia (VT) episodes occurred in four patients. The WCD appropriately defibrillated two patients with VT episodes. There were no inadequate shocks and no fatalities during the observation time. WCD wearing compliance was high, with a median wear time of 23.3 h/day.Conclusion: This retrospective analysis in a single cardiac surgery center confirms prior data on the safety and effectiveness of the WCD in patients in post‐surgery care in a real‐life setting. The WCD successfully protected patients from SCD during life‐threatening VT episodes. WCD wearing compliance was high.

Background Cardiac myxomas are the most common primary cardiac neoplasms. Case Description We present a case of a middle-aged lady with cardiac myxoma in her left atrium awaiting semi-elective surgery. During the preoperative period, the patient presented emergently with acute bilateral lower limb ischemia. This lady was fortunate to have these emboli fired towards a tissue with ischemia tolerance capacity. If these emboli had been directed toward the central nervous system, this patient would have experienced devastating complications and even death. Conclusion This presentation opens the debate on the timing of surgical intervention in myxoma patients.
