Background: The trends of concomitant CABG and multiple-valve procedures and their impact on in-hospital outcomes in the context of transcatheter aortic valve replacement are unexplored.Methods: This was a retrospective cohort study using the administrative database of the U.S. national inpatient sample from 2012 to 2018 to identify patients who underwent SAVR with or without concomitant CABG and/or multiple-valve procedures.Results: During the study period, a total of 75,763 representing 378,815 patients underwent SAVR nationwide were identified, of whom 42,993 (55.1%) experienced isolated SAVR, 27,133 (34.8%) underwent concomitant CABG, 5,637 (7.2%) underwent multiple-valve procedures, and 2,298 (2.9%) underwent both concomitant CABG and multiple-valve procedures. The rate of multiple-valve procedures increased from 6.1% in 2012 to 9.2% in 2018 (P < 0.001 for trend). In-hospital mortality was 2.1, 3.9, 7.3, and 11.2% for isolated SAVR, SAVR with CABG, SAVR with multiple-valve procedures, and SAVR with CABG and multiple-valve procedures, respectively. After propensity matching, compared to isolated SAVR, the risk ratio for in-hospital mortality associated with concomitant CABG was 1.54 (CI 1.39-1.70). In multiple-valve procedures, it was 2.36 (CI 1.97-2.83), and in concomitant CABG and multiple-valve procedures, it was 2.92 (CI 2.29-3.73).Conclusions: The proportion of patients receiving multiple-valve procedures is increasing. While concomitant CABG moderately increased in-hospital mortality, multiple-valve procedures dramatically increased in-hospital mortality and complications, even after propensity score matching

Objectives: The aim of this study was to evaluate the temporal trends of transcatheter aortic valve replacement (TAVR) in severe aortic stenosis (AS) patients with atrial fibrillation (AF) and to compare the in-hospital outcomes between TAVR and surgical aortic valve replacement (SAVR) in patients with AF.Background: Data comparing TAVR to SAVR in severe AS patients with AF are lacking.Methods: National inpatient sample database in the United States from 2012 to 2016 were queried to identify hospitalizations for severe aortic stenosis patients with AF who underwent isolated aortic valve replacement. A propensity score-matched analysis was used to compare in-hospital outcomes for TAVR vs. SAVR for AS patients with AF.Results: The analysis included 278,455 hospitalizations, of which 124,910 (44.9%) were comorbid with AF. Before matching, TAVR had higher in-hospital mortality than SAVR (3.1 vs. 2.2%, p < 0.001); however, there was a declining trend during the study period (Ptrend < 0.001). After matching, TAVR and SAVR had similar in-hospital mortality (2.9 vs. 2.9%, p < 0.001) and stroke. TAVR was associated with lower rates of acute kidney injury, new dialysis, cardiac complications, acquired pneumonia, sepsis, mechanical ventilation, tracheostomy, non-routine discharge, and shorter length of stay; however, TAVR was associated with more pacemaker implantation and higher cost. Of the patients receiving TAVR, the presence of AF was associated with an increased rate of complications and increased medical resource usage compared to those without AF.Conclusions: In-hospital mortality and stroke for TAVR and SAVR in AF, AS are similar; however, the in-hospital mortality in TAVR AF is declining and associated with more favorable in-hospital outcomes.

Rationale:Mediastinal radiotherapy is a common practice for treating breast cancer and Hodgkin's lymphoma. Radiotherapy causes cardiovascular damage and has attracted increasing attention, particularly among Hodgkin's lymphoma patients, as they receive a higher dose of radiation.Patient concerns:A 36-year-old woman with a past medical history of Hodgkin's lymphoma presented with persistent chest pain for 3 hours. She experienced exertional chest pain 1 month before when she was climbing stairs, which disappeared after a few minutes with rest, but recurred with a similar level of exertion. Three hours before admission to the emergency room, the chest pain persisted and was accompanied by diaphoresis and dyspnea.Diagnosis:Cardiogenic shock caused by radiotherapy-induced left main coronary artery disease.Interventions:Urgent angiography revealed left main coronary artery stenosis. Intravascular ultrasonography showed diffuse fibrous proliferation in the left main coronary artery. Hemodynamic instability was resolved after drug-eluting stent implantation.Outcomes:The patient was discharged uneventfully 5 days after the procedure, with a prescription for dual antiplatelet and statin therapy. She was asymptomatic with good exercise tolerance at the 3-month follow-up.Conclusion:Radiotherapy-induced isolated left main coronary artery disease is a rare complication of cancer radiotherapy and can occur years or decades after treatment. Fibrous proliferation is a characteristic pathologic change in the exposed coronary arteries.
