Infective endocarditis surgery timing.

BACKGROUND: The optimum timing of surgical intervention in complicated left-sided infective endocarditis is not well established. Guidelines from various professional societies are not consistent regarding this. Data concerning this remains limited with conflicting results. METHODS: The national inpatient database (NIS) was used to identify patients hospitalized from the year 2016 to 2020 for infective endocarditis and who underwent surgical intervention for complicated left-sided endocarditis. Primary and secondary outcomes were analyzed in patients who had surgical intervention within 7 days (early surgery group) and after 7 days (late surgery group) of the index hospitalization. RESULTS: Primary outcome [composite of all-cause death, acute cerebrovascular accident (CVA), peripheral septic emboli, intracranial or intraspinal abscess, and cardiac arrest] was better in the early surgery group compared to the late surgery group 32.6 % vs 45.1 % [adjusted Odds ratio (aOR) = 0.59, 95 % Confidence interval (CI) = 0.52-0.67, P value â‰ª 0.001]. This was mainly due to better incidence of acute CVA (15.7 %vs 24 %, aOR = 0.59, CI = 0.50-0.69, P value â‰ª 0.001), peripheral septic emboli (18.5 % vs 27.3 %, aOR = 0.60, CI = 0.52-0.70, P value â‰ª 0.001) and intracranial/intraspinal abscess (1.2 % vs 4.74 %, aOR = 0.24, CI = 0.14-0.38, P value â‰ª 0.001). There is no difference in the incidence of all-cause in-hospital death (7.57 % vs 7.75 % aOR = 0.97, CI = 0.77-1.23, P value = 0.82) or cardiac arrest (3.4 % vs 3.54 %, aOR = 0.96, CI = 0.68-1.35, P value = 0.80). CONCLUSION: Surgical intervention within 7 days of index hospitalization is associated with a better incidence of acute CVA, peripheral septic emboli, and intracranial or intraspinal abscess but not with a better incidence of all-cause in-hospital death.

TAVR vs balloon aortic valvotomy for severe aortic stenosis and cardiogenic shock: An insight from the National Inpatient Sample database.

BACKGROUND: Severe Aortic stenosis (AS) complicated by cardiogenic shock (CS) represents a grave clinical condition with limited treatment options. Evidence from small observation studies favors that Transcatheter Aortic Valve Replacement (TAVR) might be a feasible option in these patients in contrast to emergent Balloon Aortic Valvuloplasty (BAV) which is associated with very high short and long-term mortality. METHODS: 11,405 hospitalizations with severe AS complicated by CS between 2016 and 2020 were identified using the National Inpatient Sample (NIS) Database, and patients were then stratified according to whether they received TAVR or BAV. Propensity-score matching was used to account for differences in the baseline characteristics. Primary and secondary outcomes were then compared between 3485 hospitalizations in direct TAVR group and with 3485 matched hospitalizations in the BAV group. The primary outcome was a composite of all-cause in-hospital death, acute cerebrovascular accident (CVA), and myocardial infarction (MI). Secondary outcomes and safety outcomes were also compared between the two groups. RESULTS: TAVR was associated with fewer primary outcomes events as compared to BAV {36.8 % vs 56.8 %, aOR (95%CI) = 0.38(0.30-0.47)}, due to fewer all-cause in-hospital deaths {17.8 % vs 38.9 %, aOR (95%CI) =0.34 (0.26-0.43)} and MI {12.3 % vs 32.4 %, aOR (95%CI) = 0.29 (0.22-0.39)}. TAVR was associated with higher rates of acute CVA {6.17 % vs 3.44 %, aOR (95%CI) = 1.84 (1.08-3.21)} and pacemaker implantation post procedure {11.9 % vs 6.03 %, aOR (95%CI) = 2.10 (1.41-3.18)}. CONCLUSION: Direct TAVR in shock and severe Aortic stenosis is a better strategy than rescue Balloon aortic valvotomy.

Left Atrial Appendage Occlusion Device Embolization (The LAAODE Study): Understanding the Timing and Clinical Consequences from a Worldwide Experience.

BACKGROUND: Left atrial appendage occlusion device embolization (LAAODE) is rare but can have substantial implications on patient morbidity and mortality. Hence, we sought to perform an analysis to understand the timing and clinical consequences of LAAODE. METHODS: A comprehensive search of PubMed and Web of Science databases for LAAODE cases was performed from October 2nd, 2014 to November 1st, 2017. Prior to that, we included published LAAODE cases until October 1st, 2014 reported in the systematic review by Aminian et al. RESULTS: 103 LAAODE cases including Amplatzer cardiac plug (N=59), Watchman (N=31), Amulet (N=11), LAmbre (N=1) and Watchman FLX (N=1) were included. The estimated incidence of device embolization was 2% (103/5,000). LAAODE occurred more commonly in the postoperative period compared with intraoperative (61% vs. 39%). The most common location for embolization was the descending aorta 30% (31/103) and left atrium 24% (25/103) followed by left ventricle 20% (21/103). Majority of cases 75% (77/103) were retrieved percutaneously. Surgical retrieval occurred most commonly for devices embolized to the left ventricle, mitral apparatus and descending aorta. Major complications were significantly higher with postoperative LAAODE compared with intraoperative (44.4% vs. 22.5%, p=0.03). CONCLUSIONS: LAAODE is common with a reported incidence of 2% in our study. Post-operative device embolization occurred more frequently and was associated with a higher rate of complications than intraoperative device embolizations. Understanding the timings and clinical sequelae of DE can aid physicians with post procedural follow-up and also in the selection of patients for these procedures.
