[PMID: 38350743 DOI: 10.1053/j.jvca.2024.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 09/16/2023] [Accepted: 01/10/2024] [Indexed: 02/15/2024]
Abstract
OBJECTIVES To describe outcomes of reconstruction of the aortomitral continuity (AMC) during concomitant aortic and mitral valve replacement (ie, the "Commando" procedure). DESIGN A retrospective study of consecutive cardiac surgeries from 2010 to 2022. SETTING At a single institution. PARTICIPANTS All patients undergoing double aortic and mitral valve replacement. INTERVENTIONS Patients were dichotomized by the performance (or not) of AMC reconstruction. MEASUREMENTS AND MAIN RESULTS A total of 331 patients underwent double-valve replacement, of whom 21 patients (6.3%) had a Commando procedure. The Commando group was more likely to have had a previous aortic valve replacement (AVR) or mitral valve replacement (MVR) (66.7% v 27.4%, p < 0.001), redo cardiac surgery (71.4% v 31.3%, p < 0.001), and emergent/salvage surgery (14.3% v 1.61%, p = 0.001), whereas surgery was more often performed for endocarditis in the Commando group (52.4% v 22.9%, p = 0.003). The Commando group had higher operative mortality (28.6% v 10.7%, p = 0.014), more prolonged ventilation (61.9% v 31.9%, p = 0.005), longer cardiopulmonary bypass time (312 ± 118 v 218 ± 85 minutes, p < 0.001), and longer ischemic time (252 ± 90 v 176 ± 66 minutes, p < 0.001). Despite increased short-term morbidity in the Commando group, Kaplan-Meier survival estimation showed no difference in long-term survival between each group (p = 0.386, log-rank). On multivariate Cox analysis, the Commando procedure was not associated with an increased hazard of death, compared to MVR + AVR (hazard ratio 1.29, 95% CI: 0.65-2.59, p = 0.496). CONCLUSIONS Although short-term postoperative morbidity and mortality were found to be higher for patients undergoing the Commando procedure, AMC reconstruction may be equally durable in the long term.

Abstract
Infective endocarditis (IE) is a severe cardiac complication with high mortality rates, especially when surgical intervention is delayed or absent. This review addresses the expanding role of surgery in managing IE, focusing on the variation in surgical treatment rates, the impact of patient demographics, and the effectiveness of different surgical approaches. Despite varying global data, a notable increase in surgical interventions for IE is evident, with over 50% of patients undergoing surgery in tertiary centres. This review synthesizes information from focused literature searches up to July 2023, covering preoperative to postoperative considerations and surgical strategies for IE. Key preoperative concerns include accurate diagnosis, appropriate antimicrobial treatment, and the timing of surgery, which is particularly crucial for patients with heart failure or at risk of embolism. Surgical approaches vary based on valve involvement, with mitral valve repair showing promising outcomes compared to replacement. Aortic valve surgery, traditionally favouring replacement, now includes repair as a viable option. Emerging techniques such as sutureless valves and aortic homografts are explored, highlighting their potential advantages in specific IE cases. The review also delves into high-risk groups like intravenous drug users and the elderly, emphasizing the need for tailored surgical strategies. With an increasing number of patients presenting with prosthetic valve endocarditis and device-related IE, the review underscores the importance of comprehensive management strategies encompassing surgical and medical interventions. Overall, this review provides a comprehensive overview of current evidence in the surgical management of IE, highlighting the necessity of a multidisciplinary approach and ongoing research to optimize patient outcomes.

INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2024; 38:ivad207. [PMID: 38113402 PMCID: PMC10903163 DOI: 10.1093/icvts/ivad207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 11/27/2023] [Accepted: 12/18/2023] [Indexed: 12/21/2023]
Abstract
The Commando procedure for infective endocarditis is a high-risk intervention. However, infective endocarditis involving the intervalvular fibrosa is fatal in the absence of surgery. A 41-year-old man with no medical history visited a doctor with chest pain and dyspnoea. Ascending aortic dissection and vegetation on the mitral valve were noted on echocardiography, so he was transferred to our hospital. The diagnosis was dissecting aneurysm of the sinus of Valsalva and acute heart failure due to aortic regurgitation, mitral regurgitation and infective endocarditis. We decided on emergency surgery. Intraoperatively, we confirmed abscess extending to the left atrial roof and destruction of the intervalvular fibrosa, so we performed the Root-Commando procedure. The patient was saved and discharged 47 days after transfer to our hospital through the reoperation on postoperative day 30.

"UFO procedure" for massive aortic and mitral annular calcification involving left atrial and ventricular myocardium: a potential radical solution. J Cardiothorac Surg 2023; 18:185. [PMID: 37231497 DOI: 10.1186/s13019-023-02267-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Accepted: 04/04/2023] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND The "UFO procedure" was initially developed as a surgical option to enlarge the aortic annulus in patients requiring valve replacement. This technique can be employed to treat extensive endocarditis located in the intervalvular fibrous body (IVFB). One of the indications for a "UFO procedure" is massive aortic and mitral valve calcification. It is a challenging surgical procedure with a high risk of intraoperative complications. We present a 76-year-old male patient with massive aortic and mitral valve calcification involving the left atrium, the left ventricle and the left ventricular outflow tract. Both valves exhibited severe stenosis and moderate to severe regurgitation. The left ventricle was hypertrophic and the left ventricular ejection fraction was > 55%. The patient was prediagnosed with persistent atrial fibrillation. The risk of death following heart surgery (EuroSCORE II) was calculated as 9.21%. We successfully performed a so-called "UFO procedure" including replacement of both valves without annular decalcification to avoid atrioventricular dehiscence. We enlarged the IVFB and replaced the non-coronary sinus of Valsalva with doubled bovine pericardium. The left ventricular outflow tract was decalcified. The patient was transferred to a local hospital on the 13th postoperative day. CONCLUSION Successful surgical treatment to this extent was demonstrated for the first time. Due to the high perioperative mortality, the surgical treatment of patients with this constellation would be refused in most cases. In our patient, the preoperative imaging showed extreme calcification of both valves and the surrounding myocardium. Excellent preoperative planning and a highly experienced surgical team is necessary.

Abstract
Repair of concomitant aortic and mitral valvular disease with involvement of the aortomitral curtain requires a technically complex operation colloquially termed the commando procedure. Surgical outcomes of this procedure are not well described. The objective of this study was to examine outcomes of the commando procedure at our center. We identified all patients undergoing concomitant aortic and mitral valve replacements from 2004-2021. Of 363 patients, 41 underwent reconstruction of the aortomitral curtain. Survival analysis and multivariable modeling were used to examine outcomes and risk factors for mortality. The median age was 52 (IQR 44-71) years. Preoperatively, 4 of 41 (9.8%) patients had renal failure, and 10 of 41 (24.4%) had a stroke. The most common surgical indication was endocarditis in 25 of 41 (61.0%) patients. 25 of 41 (61.0%) patients underwent redo sternotomy, and 23 of 41 (56.1%) had previous prosthetic valves. Operative mortality was 14 of 41 (34.1%), and 8 of 41 (9.5%) patients received a permanent pacemaker. Survival at 1, 3, and 5 years was 55.4% (95% confidence interval (CI), 40.6-75.5%), 50.3% (35.0-72.3%), and 37.7% (19.3-73.9%) respectively. Cox proportional hazards regression identified previous sternotomy (HR 4.76, 95% CI 1.21-18.73), and female gender (HR 1.39, 95% CI 1.17-13.82) as risk factors for mortality. Patients undergoing reconstruction of the aortomitral curtain represent a high-risk population with complex surgical indications. Due to high perioperative morbidity and mortality, this procedure should be performed only when necessary. Despite a high up front morbidity burden, outcomes remain favorable for patients who survive the initial hospitalization.

Abstract
OBJECTIVES The objectives of this study were to examine operative and long-term results of combined aortic and mitral valve replacement when reconstruction of the fibrous skeleton of the heart is needed because of calcification, abscess, previous operations, or patient-prosthesis mismatch. METHODS From 1985 to 2020, 182 consecutive patients underwent combined aortic and mitral valve replacement with reconstruction of the intervalvular fibrous skeleton in all cases and also the posterior mitral annulus in 63 patients. Bovine pericardium or Dacron grafts were used for the reconstructions. Median follow-up was 7.5 (interquartile range, 2.1-12.6) years and 98% complete. RESULTS Patient mean age was 62 years; 69% had 1 or more previous valve operations, and 92% were functional class III or IV. The indications for reconstruction were extensive calcification of the fibrous skeleton in 34%, abscess in 13%, tissue damage secondary to previous operations in 39%, and patient-prosthesis mismatch of the mitral valve in 13%. Bovine pericardium was used in two-thirds of cases and Dacron grafts in one-third. Operative mortality was 13.2% and postoperative complications were common. Survival at 1, 10, and 20 years was 81.8%, 51.1%, and 23.7%, respectively. Fourteen patients required reoperation and 3 transcatheter interventions. The cumulative probability of reinterventions at 1, 10, and 20 years were 3.3%, 5.8%, and 9.1%, respectively. Most patients experienced symptomatic improvement postoperatively. CONCLUSIONS Reconstructions of the fibrous skeleton of the heart are associated with high operative mortality but the long-term results are satisfactory because most patients would not have survived without surgical intervention.

J Cardiothorac Surg 2021; 16:204. [PMID: 34321027 PMCID: PMC8320201 DOI: 10.1186/s13019-021-01583-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 07/10/2021] [Indexed: 11/26/2022] Open
Abstract
Background The Medtronic Freestyle prosthesis has proven to be a promising recourse for aortic root replacement in various indications. The present study aims to evaluate clinical outcomes and geometric changes of the aorta after Freestyle implantation. Methods Between October 2005 and November 2020, the computed tomography angiography (CTA) data of 32 patients were analyzed in a cohort of 68 patients that underwent aortic root replacement using Freestyle prosthesis. The minimum and maximum diameters and areas of the aortic annulus, aortic root, ascending aorta, and the proximal aortic arch were measured at a plane perpendicular to the long axis of the aorta using 3D multiplanar reconstruction in both the preoperative (n = 32) and postoperative (n = 10) CTAs. Moreover, volumetric changes of the aortic root and ascending aorta were quantified. Results Mean age was 64.6 ± 10.6 years. Indications for surgery using Freestyle prosthesis were combined aortic valve pathologies, aortic aneurysm or dissection, and endocarditis, with concomitant surgery occurring in 28 out of 32 patients. In-hospital mortality was 18.6%. Preoperative diameter and area measurements of the aortic annulus strongly correlated with the implanted valve size (p < 0.001). Bicuspid valve was present in 28.1% of the patients. Diameter and areas of the aortic root decreased after freestyle implantation, resulting in a reduction of the aortic root volume (45.6 ± 26.3 cm3 to 18.7 ± 4.5 cm3, p = 0.029). Volume of the aortic root and the ascending aorta decreased from 137.3 ± 65.2 cm3 to 54.5 ± 21.1 cm3 after Freestyle implantation (p = 0.023). Conclusion Implantation of the Freestyle prosthesis presents excellent results in restoring the aortic geometry. Preoperative CTA measurements are beneficial to the surgical procedure and valve selection and therefore, if available, should be considered in pre-operative planning.
