Minimally invasive cardiac surgery

Minimally invasive mitral valve surgery (MiMVS) has been increasing in prevalence. This review will focus on the approaches, the clinical outcomes, and patient selection for MiMVS. There are four minimally invasive approaches to the mitral valve: Right mini-thoracotomy, both video-assisted and fully endoscopic, robotic mitral surgery, and transapical, beating heart off-pump neochordal repair. Advantages over conventional surgery include less blood loss and transfusion, improved postoperative mobility, shorter length of stay, less postoperative atrial fibrillation, fewer surgical site infections, and improved cosmesis...

We present the case of a 61-year-old man with known Morbus Barlow disease, who presented with postoperative myocardial infarction and cardiac arrest within 1 hour after minimally invasive mitral valve surgery owing to coronary artery occlusion by native mitral valve tissue.

Background : Postoperative myocardial injury, as detected by an elevated concentration of high-sensitivity cardiac troponin I (hs-cTnI), is a common complication in cardiac surgery that may be linked to mortality. The primary aim of this study was to assess the risk factors associated with increased myocardial injury in patients undergoing minimally invasive mitral valve surgery. Methods : In this retrospective monocentric cohort study, we analyzed all patients who underwent elective minimally invasive mitral valve surgery between January 2019 and December 2022 and were subsequently admitted to our intensive care unit...

Micro-invasive totally endoscopic aortic valve replacement surgery is a minimally invasive cardiac procedure that can be performed with the help of several techniques and technologies that employ the latest innovations in instrumentation and technological advances in the field, thereby greatly limiting the overall invasiveness of the procedure. With the help of a 3-dimensional camera, long instruments, a very small thoracotomy and a soft-tissue retractor without any rib retractor, the aortic valve can be easily and safely accessed for replacement...

OBJECTIVE: Lower-limb ischemia is a complication of minimally invasive cardiac surgery with femoral cannulation. Herein, we verified our strategy using distal perfusion cannulation (DPC) against this complication. METHODS: We retrospectively assessed 91 cases of aortic valve replacement with femoral cannulation between January 2019 and March 2023. DPC was applied when lower-limb tissue oxygenation index declined by ≥20%. The cannula to femoral artery diameter ratio (C/FA) was calculated by dividing the cannula size (Fr) divided by 3 by the femoral artery inner diameter (mm)...

BACKGROUND: Prophylactic passive abdominal drainage is standard practice after distal pancreatectomy. This approach aims to mitigate the consequences of postoperative pancreatic fistula (POPF) but its added value, especially in patients at low risk of POPF, is currently being debated. We aimed to assess the non-inferiority of a no-drain policy in patients after distal pancreatectomy. METHODS: In this international, multicentre, open-label, randomised controlled, non-inferiority trial, we recruited patients aged 18 years or older undergoing open or minimally invasive elective distal pancreatectomy for all indications in 12 centres in the Netherlands and Italy...

We present the case of a minimally invasive surgical correction for failed percutaneous atrial septal defect (ASD) closure in a 57-year-old female patient with residual ASD, tricuspid regurgitation, atrial fibrillation, and embolization of one of two occluders to the superior mesenteric artery. Our surgical approach consisted of anterolateral minithoracotomy, aortic and femoral vein cannulation, cryoablation, cardiac device removal, closure of ASD with autologous pericardium, and tricuspid repair. The procedure was uneventful and patient was discharged home on postoperative day 4...

OBJECTIVES: Severe pulmonary complications such as postoperative respiratory failure can occur after minimally invasive oesophagectomy. However, the risk factors have not been well identified. This study aimed to develop a predictive model for the occurrence of postoperative respiratory failure with a large sample. METHODS: We collected data from patients with oesophageal cancer who received minimally invasive oesophagectomy at Shanghai Chest Hospital from 2019 to 2022...

The role of robotic surgery in the curative-intent treatment of esophageal cancer patients is yet to be defined. To compare short-term outcomes between conventional minimally invasive (cMIE) and robot-assisted minimally invasive esophagectomy (RAMIE) in esophageal cancer patients. PubMed, Web of Science and Cochrane Library were systematically searched. The included studies compared short-term outcomes between cMIE and RAMIE. Individual risk of bias was calculated using the MINORS and RoB2 scales. There were no statistically significant differences between RAMIE and cMIE regarding conversion to open procedure, mean number of harvested lymph nodes in the mediastinum, abdomen and along the right recurrent laryngeal nerve (RLN), 30- and 90-day mortality rates, chyle leakage, RLN palsy as well as cardiac and infectious complication rates...

Cervical ectopic pregnancies account for <1% of ectopic pregnancies. Early diagnosis may reduce the morbidity and mortality associated with treatment. A 43-year-old woman, gravida 4 para 2, presented at 5 + 6 weeks of gestation of pregnancy via in vitro fertilisation with painless vaginal bleeding. Her initial serum β-hCG level was 51,495 mIU/mL. Ultrasound showed a live ectopic pregnancy within the upper cervical canal with no sliding sign. Surgery was avoided initially due to risk of haemorrhage...

Valve surgery is common in cardiac procedures, with fasteners like COR-KNOT® and hand-tied knots used for knot securing. This study compares their efficacy in valve surgery patients. We searched PubMed, SCOPUS, and Cochrane Central until August 2023. Outcomes assessed included aortic cross-clamp time (AXT), cardiopulmonary bypass (CPB) time, valvular regurgitation, mortality, prolonged ventilatory support, atrial fibrillation, postoperative left ventricular ejection fraction (LVEF), and renal failure. Subgroup analysis was performed for minimally invasive and open cardiac surgery...

OBJECTIVES: Solitary fibrous tumours of the pleura (SFTP) are historically considered to be benign soft tissue neoplasms. However, a clinical relevant number of these neoplasms have malignant histological features. The objective of this study was to evaluate the percentage of SFTP presenting unfavorable clinical behaviour in order to predict negative long-term outcome. METHODS: A retrospective review of 74 patients treated at 4 hospitals between 1990 and 2013 was performed...

A totally endoscopic minimally invasive approach is widely used for cardiac valve surgery in normal adults. However, minimally invasive cardiac surgery during pregnancy is rarely reported. In addition to traditional median thoracotomy, totally endoscopic minimally invasive approaches can now be used for pregnant patients. We describe our experience with totally endoscopic cardiac valve surgery (TECVS) during pregnancy, which is safe for both mothers and fetuses.

BACKGROUND: Kirschner wires are widely used in trauma surgery. Their migration into the pericardium is a rare but often fatal phenomenon, requiring urgent management. CASE PRESENTATION: We describe the case of a 65-year-old patient who underwent Kirschner wire placement to treat a humeral head fracture. Three months after the operation, pleural and pericardial effusions with cardiac tamponade were observed, leading to the diagnosis of wire migration within the pericardium...

OBJECTIVES: Hybrid coronary revascularization (HCR) involves the use of minimally invasive direct coronary artery bypass grafting (CABG) to treat the left anterior descending artery (LAD), and percutaneous coronary intervention to treat non-LAD vessels. We reported the results of a comparative analysis between HCR and off-pump CABG via sternotomy (OPCABG). METHODS: Data were retrospectively collated from patients who underwent HCR or OPCABG for multivessel coronary artery disease between 2011 and 2022...

BACKGROUND: Minimally invasive surgery has emerged as a favorable alternative to conventional surgery for various cardiac conditions. This study aimed to compare the perioperative outcomes and follow-up results of the robotic approach versus the sternotomy approach for left atrial myxoma (LAM) resection. METHOD: We retrospectively analyzed the perioperative outcomes and follow-up results of 94 patients who underwent left atrial myxoma resection using either the sternotomy approach (n = 64) or the robotic approach (n = 30) at our center between January 2017 and April 2023...

BACKGROUND: Comorbidities can potentially impact the presentation or outcome of patients with pilonidal disease (PD) due to poor wound healing or increased inflammatory response. We hypothesized that certain comorbidities could lead to worse pain or higher recurrence rate. METHODS: A retrospective study was performed on all PD patients treated with standardized minimally invasive protocol at our clinic 2019-2022. Patients' demographics, comorbidities, initial/follow-up pain score, pain duration, and recurrence were recorded...

Papillary fibroelastomas (PFEs) are small, slowly growing benign cardiac tumors with clinically significant risk of embolization. Surgical excision is the definitive treatment of symptomatic PFE and is conventionally performed through a median sternotomy. In this study, we report a series of 12 patients, who underwent robotic-assisted PFE removal at the Mayo Clinic. PFE involved the mitral valve, left atrium, and tricuspid valve. No major complications occurred after the procedure, and most patients were discharged 4 days after the surgery...

INTRODUCTION: Obese patients are at risk of complications after cardiac surgery. The aim of this study is to investigate safety and efficacy of a minimally invasive approach via upper sternotomy in this setting. METHODS: We retrospectively reviewed 203 obese patients who underwent isolated, elective aortic valve replacement between January 2014 and January 2023 - 106 with minimally invasive aortic valve replacement (MIAVR) and 97 with conventional aortic valve replacement (CAVR)...
