Extra-corporeal membrane oxygenation and emergency C-section for a pregnant COVID-19 positive patient.

INTRODUCTION: Data on extra-corporeal membrane oxygenation (ECMO) therapy for pregnant patients with Coronavirus 2019 (COVID-19) infection are limited. Here we report a case of an emergency cesarean section performed while the COVID-19 positive mother was on ECMO support. CASE REPORT: A 36-year-old COVID-19 positive patient at 26 weeks gestational age presented with respiratory failure requiring extra-corporeal membrane oxygenation therapy. Nine days later fetal distress demanded an emergency C-section. After 5 weeks on ECMO, the patient was weaned off. Both mother and child were discharged. DISCUSSION: The decision to perform an urgent C-section is one that requires meticulous thought from the attending team. Pulmonary maturation is key as pregnancy may need to be terminated at any time during ECMO. CONCLUSION: Data on ECMO support for pregnant patients with COVID-19 infection are scarce. Best results can be achieved ensuring adequate anticoagulation, meticulous choice of cannulas, continued fetal monitoring, early lung maturation, and precision timing of delivery.

MitraClip as bridge to mitral valve replacement in the setting of ischemic cardiogenic shock and papillary muscle rupture.

MitraClip implantation has been reported in severe mitral regurgitation following ischemic papillary muscle rupture in surgically high-risk patients with cardiogenic shock. Here we present a case of a 68-year-old female patient who suffered an ischemic papillary muscle rupture resulting in severe mitral prolapse and had a MitraClip implanted. Three months later, due to progressive symptoms, she was taken to surgery and had an elective minimally invasive mitral valve replacement. Informed consent was given and ethics board approval was obtained.

Bench bioprosthetic aortic valve replacement in a donor heart before transplantation.

Critical donor shortages have impulsed the need to expand donor heart eligibility through the use of marginal hearts in cardiac transplantation. Donor valvular disease has been considered as an absolute contraindication for transplant. A 39-year-old male patient with end-stage non-compaction cardiomyopathy, an INTERMACS II heart failure, and a left ventricular ejection fraction of 8% was taken to an orthotopic heart transplantation. During donor bench graft examination, a congenital bicuspid and calcified aortic valve was found. The native bicuspid valve was removed and the annular calcification debrided; a #21 bioprosthetic aortic valve was then implanted.

Peri-operative nutrition in cardiovascular surgery: current pitfalls and future directions.

In the field of cardiovascular surgery, many areas are frequently evaluated to improve patient outcomes. Even though cardiac surgery has advanced significantly, peri-operative nutrition remains an area needing special attention and is under-considered in patient results. The three portions of cardiac surgical nutrition optimization are pre-operative, intra-operative and post-operative. All these, merit important clinical intervention which when done properly can significantly improve patient recovery and reduce morbidity and mortality. Here we provide a narrative review and recommendations for peri-operative nutritional optimization in cardiac surgery.

Emergency CABG for a migrated stent in a COVID-19 positive patient.

Percutaneous coronary interventions (PCI) have become a standard of treatment worldwide. Despite high safety rates, iatrogenic complications caused by stent dislodgements do exist in 0.21% of cases and most require emergency coronary artery by-pass grafting (CABG). Here we present a case of a coronavirus disease 2019 positive 40-year-old male patient presenting with STEMI due to thrombotic lesions in his left coronary trunk. The patient is taken to PCI and stent placement. Stent dislodgement results in the need for emergency CABG and stent removal. Informed consent and ethics approval were obtained.

COVID-19 and cardiothoracic surgery: Effects on training and workforce utilization in a global pandemic.

BACKGROUND: The COVID-19 pandemic has disrupted all aspects of healthcare, including cardiothoracic surgery (CTS). We sought to determine the pandemic's impact on CTS trainees' educational experiences. METHODS: A survey was developed and distributed to members of the Thoracic Surgery Residents Association and other international CTS trainees. Trainees were asked to evaluate their cumulative experiences and share their overall perceptions of how CTS training had been impacted during the earliest months of the COVID-19 pandemic (i.e., since March 01, 2020). Surveys were distributed and responses were recorded June 25-August 05, 2020. In total, 748 surveys were distributed and 166 responses were received (overall response rate 22.2%). Of these, 126 of 166 responses (75.9%) met inclusion criteria for final analysis. RESULTS: Final responses analyzed included 45 of 126 (35.7%) United States (US) and 81 of 126 (64.3%) international trainees, including 101 of 126 (80.2%) senior and 25 of 126 (19.8%) junior trainees. Most respondents (76/126, 43.2%) lost over 1 week in the hospital due to the pandemic. Juniors (12/25, 48.0%) were more likely than seniors (20/101, 19.8%) to be reassigned to COVID-19-specific units (p < .01). Half of trainees (63/126) reported their case volumes were reduced by over 50%. US trainees (42/45, 93.3%) were more likely than international trainees (58/81, 71.6%) to report reduced operative case volumes (p < .01). Most trainees (104/126, 83%) believed their overall clinical acumen was not adversely impacted by the pandemic. CONCLUSIONS: CTS trainees in the United States and abroad have been significantly impacted by the COVID-19 pandemic, with time lost in the hospital, decreased operative experiences, less time on CTS services, and frequent reassignment to COVID-19-specific care settings.

Surgical removal of intravascular leiomyomas with intracardiac extension: A two-case report.

Leiomyomatosis is a uterine condition that can rarely present with extrauterine involvement. Intravenous and intracardiac extensions are extremely rare presentations and, in these cases, the intra-cardiac mass may be confused with a cardiac myxoma and can be associated with pulmonary embolism. Here we report two cases of successful surgically removed intracardiac leiomyomas under cardiopulmonary bypass.

Low intra-operative diagnostic accuracy does not affect postoperative treatment of acute appendicitis.

BACKGROUND: The intra-operative classification of appendicitis defines postoperative treatment. The correct designation can influence patient recovery, complications and hospital costs. Recent research has shown that intra-operative classification criteria varies among surgeons, and is not always the same as the pathologist's report. Classification accuracy can lower costs by preventing unnecessary treatment or sub-optimal interventions. METHODS: During a period of 4 months, N = 133 appendix specimens were received and evaluated by the pathology department of a single teaching hospital. Five surgeons extracted the specimens and one experienced pathologist drew the histopathology reports. A comparison between the surgeons' classifications and the pathologist's was made. Classification accuracy was determined and statistical analyses was performed using chi-square, and p values were obtained. A p < 0.05 was considered significant. RESULTS: A total of N = 133 specimens were obtained, 127 belonged to patients following emergency surgery due to acute abdominal pain; the other six were from elective hemi-colectomies for right colonic adenocarcinomas, and were not included. Of the 127 specimens analyzed, 14 (11%) were negative, 21 (16.5%) were edematous, 81 (63.7%) were phlegmonous and 11 (8.6%) were gangrenous. A total of 18 (14%) perforated appendices were also reported. Surgical accuracy was 60.6% (N = 67) with a statistically significant p < 0.001. Only five patients with incorrect intraoperative classifications received unnecessary or lacked treatment. CONCLUSIONS: An overall accuracy of 60.6% is seen when the surgical classification is compared to the pathological classification. Although the surgeons' accuracy is low when comparing intra-operative versus histopathological classification, this variation in designation does not affect postoperative treatment significantly.

Low-Cost Innovations in Global Cardiac Surgery.

Cardiovascular diseases are the leading cause of morbidity and mortality worldwide, costing the lives of 18 million people annually, with up to one-third being attributable to cardiac surgical conditions. Approximately 6 billion people do not have access to safe, timely, and affordable cardiac surgery, predominantly affecting populations living in low-middle income countries. Cardiac surgical care is costly, resulting in few centers in variable-resource contexts operating continuously or with the resources observed in higher-resource environments. As a result, innovations may be formally developed or informally adopted to bypass resource constraints and ensure care delivery. Innovations have been observed across the cardiac surgical care continuum and across settings, potentially benefiting both high-income countries, where growing health care costs are becoming unsustainable, and low- and middle-income countries, where competing health agendas may limit investments into cardiac surgery. This narrative review attempts to address the costs associated with cardiac surgery, placing an emphasis on frugal innovations in the perioperative and postoperative care spectrum.

Cardiovascular Surgery in Panama: Evolution and Training.

Cardiovascular surgery in Panama has depended on constant contributions and support from other developed countries. Although cardiac surgery has reached important milestones, cardiac surgery training is still evolving. Here, we provide a look into both the development and training of cardiac surgery in the Republic of Panama and the importance of international training.

Twenty-five Years of Lung Transplantation in Medellín: Overcoming the Challenges of an Emerging Country.

The first successful lung transplant in Colombia was performed on October 28, 1997 in Medellín by Alberto Villegas Hernández at the "Clínica Cardiovascular Santa María" today called the Cardio VID Clinic. Here we present both survival outcomes and characteristics of the oldest and most experienced lung transplant program in Colombia. We conducted a retrospective study of all patients taken to lung transplantation at the Cardio VID Clinic in Medellín, Colombia from October 1997 to October 2022. Patient information from our institutional database and transplant archives were retrieved and reviewed. From October 1997 to October 2022, a total of 153 patients underwent orthotopic lung transplantation at our institution in Medellín, Colombia. Mean recipient age was 48±13 years, the youngest patient was 15 years old and the oldest patient was 73 years old at the time of transplant. 74 (48,4%) patients were men and 79 (51,6%) were women. Lung transplant survival in Medellin at 1-month, 1-year, 5-years and 10-years were 68%, 50%, 31% and 12% respectively. Although health care coverage in Colombia reaches nearly 100%, socioeconomic hurdles during post-transplant care, non-returning patients, infections and traumatic donor deaths lead to high mortality rates. Due to these factors, establishing successful and sustainable lung transplant programs in these settings is challenging.

Miniature Minimally Invasive Pulmonary Banding in Neonates (MINI-MICS): A Novel Technique.

Single-ventricular cardiopathies are challenging conditions requiring multiple surgical interventions to hopefully achieve adulthood. In neonates, pulmonary artery banding allows ventricular adaptation and pulmonary vascular bed protection. Here we present a novel minimally invasive approach to pulmonary artery banding through a 1.5 cm left parasternal minithoracotomy. This technique not only allows for a less traumatic first procedure but also a less manipulated mediastinum and untouched sternum for the consequent surgeries to come. This technique is reproducible in experienced hands and shows favorable and promising results when performed properly.

Aortic root replacement in a patient with previous coronary artery bypass.

Acute type A thoracic aortic dissection is a life-threatening condition that requires rapid diagnosis and prompt surgical intervention. Prior cardiac surgery is recognized as a predisposing risk factor. Here, we report a rare case and successful surgical repair of a late presenting acute type A thoracic aortic dissection four years after a three-vessel coronary artery bypass grafting. Resection of the aortic valve and aneurysmal tissue was required, reconstruction was done with a composite graft, and the native coronary ostia and aorto-saphenous buttons were preserved.

Cardiac Surgery and Small Island States: A Bridge Too Far?

BACKGROUND: Small island developing states (SIDS) make up nearly 1% of the world's population, with 65 million people across 58 countries. Small island developing states have some of the highest rates of rheumatic heart disease in addition to a substantial burden of congenital heart defects and a growing burden of ischemic heart disease. Here, we present an overview of cardiac surgical services in SIDS, with a focus on Papua New Guinea, the Maldives, and Aruba. METHODS: We performed a literature review using the PubMed/MEDLINE and Google Scholar databases to identify articles describing cardiac surgery services in SIDS. Case studies of the history and current state of cardiac surgery in Papua New Guinea, the Maldives, and Aruba were developed and informed by local clinical experience. RESULTS: Nine SIDS have independent cardiac surgical centers and 5 SIDS have local centers supported by visiting teams. Papua New Guinea started cardiac surgery in 1993 and is served by a public center, performing nearly 100 cardiac surgeries per year. The Maldives introduced cardiac surgery services in 2018, with 1 local cardiac surgeon supported by Nepalese cardiac surgeons, performing 33 cardiac surgeries in 15 months. In Aruba, no local cardiac center exists and over 150 patients are sent abroad for cardiac surgery, representing 12% of total health spending. CONCLUSIONS: Small island developing states have limited availability of cardiac surgery but pressing clinical needs. Independent cardiac centers exist with acceptable outcomes and lower costs than foreign treatment, which suggests the need to strengthen regionalization models to deliver cardiac surgical care in SIDS.

Cardiothoracic Surgery in the Caribbean.

INTRODUCTION: Despite being one of the main vacation destinations in the world, health care in the Caribbean faces many difficulties. The challenges involved in these islands' medical care range from low-resource institutions to lack of specialized care. In the field of thoracic and cardiac surgery, many limitations exist, and these include the lack of access to cardiac surgery for many small islands and little governmental funding for minimally invasive approaches in thoracic surgery. METHODS: Literature review was done using PubMed/MEDLINE and Google Scholar databases to identify articles describing the characteristics of thoracic and cardiac surgery departments on Caribbean islands. Articles on the history, current states of practice, and advances in cardiothoracic surgery in the Caribbean were reviewed. RESULTS: Regardless of the middle to high-income profile of the Caribbean, there are significant differences in the speed of technological growth in cardiothoracic surgery from island to island, as well as disparities between the quality of care and resources. Many islands struggle to advance the field of cardiothoracic surgery both through lack of local cardiac surgery centers and limited financial funding for minimally invasive thoracic surgery. CONCLUSIONS: Cardiac and thoracic surgery in the Caribbean depend not only on the support from local government policies and proper distribution of healthcare budgets, but efforts by the surgeons themselves to change and improve institutional cultures. Although resource availability still remains a challenge, the Caribbean remains an important region that deserves special attention with regard to the unmet needs for long-term sustainability of chest surgery.

The Women of Colombian Thoracic and Cardiac Surgery: A Survey-based Assessment.

In Colombia, the number of younger female surgeons is increasing along with a growing interest in thoracic and cardiac surgery. It is our duty to motivate young female surgeons in pursuing a career in chest surgery to answer the already growing deficit of cardio-thoracic surgeons.

Video-Assisted Thoracoscopy For Penetrating Cardiac Box Injury in Stable Patients.

INTRODUCTION: In high-volume trauma centers, especially in developing countries, penetrating cardiac box injuries are frequent. Although many aspects of penetrating chest injuries have been well established, video-assisted thoracoscopy is still finding its place in cardiac box trauma and algorithmic approaches are still lacking. The purpose of this manuscript is to provide a streamlined recommendation for penetrating cardiac box injury in stable patients. METHODS: Literature review was carried out using PubMed/ MEDLINE and Google Scholar databases to identify articles describing the characteristics and concepts of penetrating cardiac box trauma, including the characteristics of tamponade, cardiac ultrasound, indications and techniques of pericardial windows and, especially, the role of video-assisted thoracoscopy in stable patients. RESULTS: Penetrating cardiac box injuries, whether by stab or gunshot wounds, require rapid surgical consultation. Unstable patients require immediate open surgery, however, determining which stable patients should be taken to thoracoscopic surgery is still controversial. Here, the classification of penetrating cardiac box injury used in Colombia is detailed, as well as the algorithmic approach to these types of trauma. CONCLUSION: Although open surgery is mandatory in unstable patients with penetrating cardiac box injuries, a more conservative and minimally invasive approach may be undertaken in stable patients. As rapid decision-making is critical in the trauma bay, surgeons working in high-volume trauma centers should expose themselves to thoracoscopy and always consider this possibility in the setting of penetrating cardiac box injuries in stable patients, always in the context of an experienced trauma team.

Cardiac Surgery Air-Bridging in the Caribbean.

The need for air-bridging of cardiac patients in the Caribbean for surgical treatment abroad has many downfalls. Besides the burden on national health budgets, the risks involved with transfers, and delayed treatment, patients depend completely on care abroad.
