RESUMEN
Heart transplant remains the criterion standard treatment for patients in end-stage heart failure. Improvement in the post-heart transplant outcomes in the last decade has contributed to increased demand for organs. Worldwide each year, more than 5000 heart transplants are performed and 50,000 people become candidates for heart transplant. In the last 50 years, there have been several attempts to expand donor criteria to increase the donor pool. Despite making hepatitis C virus, opioid overdose death, old age allowable and changing the allocation system, the gap between supply and demand is widening and unfortunately, thousands die every year waiting due to the critical shortage of organs. New technologies for heart donation after circulatory death have emerged, particularly normothermic regional organ perfusion and ex-vivo heart perfusion using organ care systems. However, these technologies still do not fill the gap. Continuous advancements in areas such as regenerative medicine and xenotransplantation, among others, are needed to overcome the shortage of heart donors for heart transplantation.
RESUMEN
BACKGROUND: Coronavirus (COVID-19) infection exposes patients with heart failure specially who are on mechanical support to a higher risk of morbidity and mortality. AIMS: To investigate the impact of COVID-19 infection on left ventricular assist device (LVAD) thrombosis in heart failure patients. MATERIALS & METHODS: We searched the medical electronic records, Medline, PubMed and Cochrane databases for; (LVAD) AND (thrombosis)) AND (covid-19)) AND (heart failure). We divided cases reported into, LVAD thrombosis with COVID-19 infection and compare them with LVAD thrombosis without COVID-19 infection. Demographic data, LVAD device, presentation, treatment and outcomes were reviewed in all the LVAD thrombosis patients. RESULTS: In addition to our case, 8 other cases of LVAD thrombosis associated with COVID and 9 cases of LVAD thrombosis without covid infection were found. Patients with Covid infection had worse presentation and outcomes (3 deaths VS. 1 death in non-covid group). DISCUSSION: In LVAD patients, pump malfunction due to thrombus development in the inflow cannula, device body, or outflow graft can result in hemodynamic instability, hemolysis and other life-threatening complications. COVID infection significantly increases the risk of mortality in LVAD patient by accelerating the pump thrombosis due to elevated levels of endothelial protein C receptor and thrombomodulin along with procoagulants such as factor VIII, P-selectin, and von Willebrand factor. CONCLUSION: Significant morbidity and mortality are attributed to LVAD thrombosis, which are exasperated by prothrombotic conditions created in COVID-19 infections.

BACKGROUND: In the West, piecemeal endoscopic resection remains the primary treatment for large colon polyps (LCP), as most recurrences are believed to be benign and resectable with follow-up endoscopy. However, invasive malignancy at the site of prior piecemeal endoscopic mucosal resection has been reported in the Asian literature. This study aims to identify the incidence of and the risk factors for local recurrence with malignancy after endoscopic resection of LCP with high-grade dysplasia (HGD). METHODS: In this retrospective cohort study, we identified patients undergoing complete endoscopic resection of LCPs (≥ 20 mm) with HGD at the Cleveland Clinic between January 2000 and December 2016. Demographic, endoscopic, and pathologic data were collected. All subsequent endoscopic and pathology reports were reviewed to identify recurrence. The cumulative incidence of malignancy at the polypectomy site was determined and univariate analysis was performed to assess risk factors. RESULTS: A total of 254 LCPs with HGD were resected in 229 patients. Mean polyp size was 29.2 mm. There were 138 lesions resected in piecemeal fashion and 116 en-bloc. After a median follow-up of 28.7 months for the entire cohort, local recurrence with malignancy was diagnosed in six cases. Median time to malignancy diagnosis was 28.5 months. All malignant cases occurred after piecemeal resection and none after en-bloc resection (HR 11.4; 95% CI 0.48-273). CONCLUSION: Malignancy after endoscopic resection of LCPs with HGD is uncommon and may be associated with piecemeal resection. When possible, en-bloc resection should be the goal for the management of LCPs.

INTRODUCTION: The American Society of Anesthesiologists (ASA) physical status classification system was developed as a simple categorization of patients' physiological status that predicts the operative risk. Peroral endoscopic myotomy (POEM) is a less invasive alternative to surgical myotomy in achalasia. As such, POEM seems to be an appealing option for high-risk patients with achalasia. However, there are no studies which systematically analyzed the outcomes of POEM among patients with different ASA classes. Hence, we aimed to compare the safety and efficacy of POEM in patients with lower and higher ASA classes. METHODS: Medical records of all achalasia patients who underwent POEM at our institution between April 2014 and May 2019 were reviewed. Patients were categorized arbitrarily into two groups, lower ASA class (ASA I and II combined) and higher ASA class (ASA class III and IV combined). Demographic and procedural details, timed barium swallow (TBE), high-resolution esophageal manometry (HREM), pH study findings and Eckardt scores were compared between the two groups. Baseline characteristics were compared using Chi-square test and two-sample t-test for categorical and continuous variables, respectively. RESULTS: A total of 144 patients met our study criteria (lower ASA class, n = 44; and higher ASA class, n = 100). Patients in higher ASA class were significantly more obese and older. More patients in lower ASA class had prior Heller myotomy and more patients in higher ASA Class had prior botulinum toxin injections. Procedural parameters were similar in both groups. Procedural complications were infrequent and were also similar in the two groups. The length of stay, 30-day readmission rate, reflux symptoms and esophageal pH study findings were also comparable between the two groups. Treatment success was similar in both groups, 97.7% in lower ASA class versus 92% in higher ASA class (p = 0.19). At 2-month follow-up, both groups had significant improvement in HREM and TBE parameters. CONCLUSION: POEM is a very safe and highly effective treatment option for achalasia patients with advanced ASA class similar to lower ASA class patients. POEM may be considered as the preferred choice for myotomy in these high-risk achalasia patients due to its low morbidity and high efficacy.

BACKGROUND: Colonoscopy performance by gastroenterologists has been shown to be associated with lower rates of developing interval colorectal cancer. However, it is unclear if this difference among specialists stems from a difference in meeting colonoscopy quality indicators. OBJECTIVE: The purpose of this study is to determine and compare the rates of colonoscopy quality indicators between different specialties. DESIGN: This is a cohort study of patients undergoing screening colonoscopy investigating quality metrics as compared by the proceduralist specialty. SETTING: All screening colonoscopies performed at the Cleveland Clinic between 2012 and 2014 were followed by manual chart review. PATIENTS: Average-risk patients, ≥50 years of age, who had a complete screening colonoscopy were included. MAIN OUTCOME MEASURES: Adenoma detection rate, cecal intubation rate, withdrawal time, and other nonestablished overall and segment-specific rates were calculated and compared using t tests. RESULTS: A total of 4151 patients were included in the analysis. Colonoscopies were performed by 54 (64.3%) gastroenterologists, 21 (25%) colorectal surgeons, and 9 (10.7%) general surgeons. Gastroenterologists had the highest overall adenoma detection rate (28.6 ± 1.2; p < 0.001), followed by colorectal surgeons (24.3 ± 1.5) and general surgeons (18.4 ± 2.3), as well as the highest adenoma detection rate in men (34.7 ± 1.3; p < 0.001), followed by colorectal surgeons (28.2 ± 1.6) and general surgeons (23.7 ± 2.6). Similarly, gastroenterologists had the highest adenoma detection rate in women (24.3 ± 1.1; p < 0.001), followed by colorectal surgeons (21.6 ± 1.4) and general surgeons (12.9 ± 2.0). Withdrawal time was the longest among general surgeons (11.1 ± 5.5; p = 0.041), followed by colorectal surgeons (10.94 ± 5.2) and gastroenterologists (10.16 ± 1.26). LIMITATIONS: We could not adjust for some procedure-related details such as retroflexion in the right colon and the use of end-of-scope devices. CONCLUSIONS: In this study, only gastroenterologists met the currently accepted overall and sex-specific adenoma detection rate benchmarks. They also outperformed nongastroenterologists in many other nonestablished quality metrics. See Video Abstract at http://links.lww.com/DCR/B232. CALIDAD DE LA COLONOSCOPIA: UNA COMPARACIÓN ENTRE GASTROENTERÓLOGOS Y NO GASTROENTERÓLOGOS: Se ha demostrado que el rendimiento de la colonoscopia por parte de los gastroenterólogos, se asocia con tasas más bajas de cáncer colorrectal en intervalos de desarrollo. Sin embargo, no está claro si esta diferencia entre especialistas, se deriva de una diferencia en el cumplimiento de los indicadores de calidad de la colonoscopia.El propósito del estudio, es determinar y comparar las tasas de indicadores de calidad de colonoscopia entre diferentes especialidades.Este es un estudio de cohorte de pacientes sometidos a una colonoscopia de detección, que investiga métricas de calidad en comparación con la especialidad de procesos.Todas las colonoscopias de detección realizadas en la Clínica Cleveland entre 2012 y 2014, fueron seguidas por una revisión manual del expediente.Pacientes de riesgo promedio, ≥50 años de edad que se sometieron a una colonoscopia de detección completa.La tasa de detección de adenomas, tasa de intubación cecal, tiempo de retirada y otras tasas generales y específicas de segmento no establecidas, se calcularon y compararon usando pruebas t.Un total de 4,151 pacientes fueron incluidos en el análisis. Las colonoscopias fueron realizadas por 54 (64.3%) gastroenterólogos, 21 (25%) cirujanos colorrectales y 9 (10.7%) cirujanos generales. Los gastroenterólogos tuvieron la tasa de detección más alta de adenomas en general (28.6 ± 1.2; p < 0.001), seguidos por los cirujanos colorrectales (24.3 ± 1.5) y los cirujanos generales (18.4 ± 2.3), así como la tasa de detección más alta de adenoma en hombres (34.7 ± 1.3; p < 0.001) seguido por cirujanos colorrectales (28.2 ± 1.6) y cirujanos generales (23.7 ± 2.6). Del mismo modo, los gastroenterólogos tuvieron la tasa más alta de detección de adenoma en mujeres (24.3 ± 1.1; p < 0.001), seguidos por los cirujanos colorrectales (21.6 ± 1.4) y los cirujanos generales (12.9 ± 2.0). El tiempo de extracción fue el más largo entre los cirujanos generales (11.1 ± 5.5; p = 0.041) seguido por los cirujanos colorrectales (10.94 ± 5.2) y los gastroenterólogos (10.16 ± 1.26).No pudimos ajustar algunos detalles relacionados con el procedimiento, tales como la retroflexión en el colon derecho y el uso de accesorios endoscópicos.En este estudio, solo los gastroenterólogos cumplieron con los índices de referencia actualmente aceptados, de detección de adenomas en general y específicas de género. También superaron a los no gastroenterólogos en muchas otras métricas no establecidas de calidad. Consulte Video Resumen en http://links.lww.com/DCR/B232. (Traducción-Dr. Fidel Ruiz Healy).

BACKGROUND: Clostridium difficile infection (CDI) is one of the leading causes of health-care-associated infections in the USA. There are limited data available regarding CDI in hospitalized patients with inflammatory bowel disease-related ileal pouch. AIMS: This study aimed to evaluate the demographics, clinical features, risk factors, and admission outcomes among hospitalized patients with CDI-related pouchitis (CDP). METHODS: Retrospective chart review was performed for patients who were admitted to our institute for pouchitis between 2013 and 2016 to identify patients with CDP. Logistic regression analysis was performed to assess the risk factors associated with CDP. RESULTS: A total of 160 subjects with pouchitis had a total of 218 admissions during the study period. Primary admission diagnosis was pouchitis or inflammatory bowel disease flare-up for 202 (93%) admissions. Clostridium difficile was tested at least once for 72 patients, and the diagnosis of CDP was established for 16 (10%) patients. All patients with CDP were symptomatic, 13 (81%) had diarrhea, 8 (50%) had abdominal pain, 7 (44%) had nausea/vomiting, and 2 (13%) had gastrointestinal bleeding. On multivariable analysis, only body mass index > 25 (OR 0.25, 95% CI 0.06-0.94, p = 0.048) was significantly associated with decreased risk of CDP. No patients in CDP cohort were admitted to ICU, died at the hospital, or readmitted in 30 days after the discharge. CONCLUSIONS: In our cohort, obesity was associated with low risk of CDP among hospitalized patients with pouchitis. This finding warrants further validation in prospective studies.

BACKGROUND: Peroral endoscopic myotomy (POEM) is an appealing treatment for older patients, as it is minimally invasive but highly efficacious similar to surgical myotomy. However, there is a lack of systematic studies analyzing POEM outcomes in young (< 65 years) versus geriatric patients (≥ 65 years). Hence, we aimed to compare the safety and efficacy of POEM in young versus geriatric patients. METHODS: Records of all achalasia patients who underwent POEM at our institution between April 2014 and May 2019 were reviewed. Patients were categorized into two groups: young (< 65 years) and old (≥ 65 years). Demographic and procedural details, timed barium esophagram (TBE), high-resolution manometry (HREM), pH study findings and Eckardt scores were compared between the two groups. Post-POEM Eckhardt score of ≤ 3 was defined as treatment success. RESULTS: A total of 148 patients met the study criteria (young = 93; old = 55). Younger patients were more likely to have lower TBE height at 1 min but wider TBE width at 5 min. The rest of the pre-operative parameters and Eckardt scores were similar in the two groups. Young patients were more likely to have undergone prior Heller myotomy, while Botox injections were common in the older group. The operative details and outcomes were similar in the two groups. Treatment success rates were similar in both groups (94.9% young vs. 94.7% in old patients, p = 1.00). At 2-month follow-up, both groups showed significant improvements in Eckhardt scores and HREM parameters; however, older patients showed greater improvement in TBE height at 1 and 5 min. The rates of symptomatic GERD and abnormal esophageal pH study findings were similar in the two groups. CONCLUSION: POEM was safe and highly effective treatment for geriatric patients with achalasia. These findings suggest that POEM might emerge as the preferred approach for myotomy in this patient population.

Peripheral vision loss results in the inability to detect objects in the peripheral visual field which affects the ability to evaluate and avoid potential hazards. A different number of assistive navigation systems have been developed to help people with vision impairments using wearable and portable devices. Most of these systems are designed to search for obstacles and provide safe navigation paths for visually impaired people without any prioritisation of the degree of danger for each hazard. This paper presents a new context-aware hybrid (indoor/outdoor) hazard classification assistive technology to help people with peripheral vision loss in their navigation using computer-enabled smart glasses equipped with a wide-angle camera. Our proposed system augments users' existing healthy vision with suitable, meaningful and smart notifications to attract the user's attention to possible obstructions or hazards in their peripheral field of view. A deep learning object detector is implemented to recognise static and moving objects in real time. After detecting the objects, a Kalman Filter multi-object tracker is used to track these objects over time to determine the motion model. For each tracked object, its motion model represents its way of moving around the user. Motion features are extracted while the object is still in the user's field of vision. These features are then used to quantify the danger using five predefined hazard classes using a neural network-based classifier. The classification performance is tested on both publicly available and private datasets and the system shows promising results with up to 90% True Positive Rate (TPR) associated with as low as 7% False Positive Rate (FPR), 13% False Negative Rate (FNR) and an average testing Mean Square Error (MSE) of 8.8%. The provided hazard type is then translated into a smart notification to increase the user's cognitive perception using the healthy vision within the visual field. A participant study was conducted with a group of patients with different visual field defects to explore their feedback about the proposed system and the notification generation stage. The real-world outdoor evaluation of human subjects is planned to be performed in our near future work.

Patients with atrial fibrillation not associated with other cardiac conditions require different individualized treatment strategies. However, in all patients it is critical to address modifiable risk factors, assess stroke risk, minimize atrial fibrillation burden, and identify the patient's individual goals of care.
RESUMEN
Background Plantar fasciitis is characterized by heel pain and is often associated with extended periods of walking or standing, improper footwear, and biomechanical imbalances. This condition primarily affects the bottom of the foot, particularly the area where the heel meets the arch. Despite its prevalence, the potential systemic effects, especially the relationship with cardiovascular disease (CVD) risk factors, require further illumination. This study explores the association between chronic plantar fasciitis and elevated C-reactive protein (CRP) levels in individuals with cardiovascular risk factors. Methods A cross-sectional study of 400 patients with foot or ankle pain was initially assessed clinically and with ultrasound or MRI scans. After excluding those with confounding factors for elevated CRP, 295 patients with concurrent diabetes, hypertension, or dyslipidemia were analyzed. We investigated the correlation between plantar fasciitis and elevated CRP levels, defined as >1 mg/L, in the context of cardiovascular risk assessment. Results The study indicated that nearly half of the patients suffering from foot or ankle pain were diagnosed with plantar fasciitis, accounting for 47.8% of cases. A statistically significant association was observed between plantar fasciitis and elevated CRP levels (p=0.035). Furthermore, a substantial correlation was found between high BMI and plantar fasciitis, but no gender-specific disparity was noted. Elevated CRP levels were significantly associated with diabetes, hypertension, and dyslipidemia. Discussion A definitive cause-and-effect relationship between plantar fasciitis and systemic inflammation has not been established; our study suggests that chronic plantar fasciitis may be more than a localized condition and could be indicative of systemic inflammation, which is known to be a factor in atherosclerosis and CVD. The observed correlation between increased CRP levels and plantar fasciitis suggests that plantar fasciitis might be a clinical indicator of systemic inflammation and could improve the assessment of CVD risk. Conclusions Elevated levels of CRP, associated with chronic plantar fasciitis, suggest a link to systemic inflammation, which could elevate the risk of CVD. Identifying plantar fasciitis as a marker for systemic inflammation in patients with CVD risk factors, including diabetes, hypertension, and dyslipidemia, underscores the importance of thorough cardiovascular evaluations in individuals with persistent heel pain. Further longitudinal and interventional research is essential to substantiate these preliminary findings and understand their impact on CVD risk management and treatment.
RESUMEN
Gastric intestinal metaplasia (GIM), a common histologic finding, is associated with increased risk of gastric cancer, and GIM associated with Helicobacter pylori infection is classified as an environmental metaplastic atrophic gastritis. Patients may be asymptomatic or present with various dyspeptic symptoms. Autoimmune metaplastic atrophic gastritis is a less common but important cause of chronic gastritis. The Correa cascade describes the evolution of precancerous mucosal changes that lead to development of GIM, with differentiation of 2 histologic types of GIM (complete and incomplete) and the consequences of each type. The risk of progression to malignancy is higher with incomplete GIM. It is also higher for those who immigrate from regions with a high incidence of H pylori infection to areas where the incidence is low. Guidelines regarding endoscopic management of GIM vary by geographic region.

BACKGROUND: Sleeve gastrectomy (SG) is an effective treatment option for patients with obesity. Robotic sleeve gastrectomy (RSG) is reported to have worse short-term patient outcomes compared to laparoscopic SG (LSG), but prior studies may not have accounted for evolving technology, including stapler utilization. OBJECTIVE: This study compared RSG and LSG outcomes over different time periods. SETTING: Academic Hospital. MATERIAL AND METHODS: The 2015 to 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project (MBSAQIP) databases were used. Matched cohort analyses compared adverse outcomes within 30 days for the 2015-2018 and 2019-2021 cohorts. Bivariate and regression models compared cohorts using Stata/MP 17.0. RESULTS: Seven hundred sixty-eight thousand and sixty-nine SG were analyzed. Over the 7-year study period, all patient outcomes, operation length (OL), and length of stay (LOS) trended downward for RSG, except surgical site infection (SSI). In the 2015-2018 cohort, leak was significantly higher with RSG (OR 1.53), and OL and LOS longer (p < 0.001). In the 2019-2021 cohort which corelated with a significant increase in robotic cases, leak (OR 1.36), SSI (OR 1.46), and morbidity (OR 1.11) were higher with RSG. While the mean difference in OL and LOS decreased between the two time periods, they remain longer for RSG (p < 0.001). CONCLUSION: While RSG and LSG are safe with similar mortality, RSG continues to be associated with higher rates of morbidity, leak, and SSI, as well as longer OL, hospital LOS, and higher cost. The study is limited by the ability to account for the impact of surgeon experience and stapler utilization on outcomes.

Background: The pulsed-electron avalanche knife (PEAK) PlasmaBlade provides an atraumatic, scalpel-like cutting precision and electrocautery-like hemostasis. PlasmaBlade operates near body temperature, and its long, thin, and malleable tip can overcome the limitations of a surgical knife. In this study, we aimed to evaluate our clinical experience and histopathological outcomes of septal myectomy using PlasmaBlade. Methods: Electronic medical records were reviewed for preoperative, operative, and follow-up data of the patients who underwent septal myectomy using PEAK PlasmaBlade at our institute between January 2019 and December 2022. Histopathology of the myectomy specimens was reviewed for the depth of muscle necrosis and compared with the left atrial appendage (LAA) specimen. Results: Twenty-nine patients underwent septal myectomy using the PEAK PlasmaBlade. No mortality was reported. The mean age was 60.6 ± 12.5 years, and 58.6% of patients were male. Peak left ventricular outflow tract (LVOT) gradients were 40.5 ± 34.9â mmHg at rest and 56.5 ± 34.9â mmHg after provocation. Concomitant procedures performed were LAA ligation in 20 (69.0%), aortic valve replacement in 5 (17.2%), and coronary artery bypass grafting in 3 (10.3%) patients. Postoperative complications were complete heart block in one (3.4%) and ventricular septal defect in two (6.9%) patients. Both the ventricular septal defects were identified intraoperatively and repaired. Histopathology of myectomy specimens demonstrated cautery artifact limited to <50â µm depth compared to >1,000â µm with conventional electrocautery. At a mean follow-up of 8.4 ± 10.3 months, the mean LVOT gradient was 4.4 ± 5.8â mmHg at rest and 9.5 ± 3.3â mmHg after provocation. All patients were alive and in New York Heart Association class I/II. No patient developed complications or required reintervention or reoperation. Conclusion: Adequate septal myectomy can be precisely and safely performed using the PEAK PlasmaBlade with minimal collateral damage.
RESUMEN
Quadricuspid aortic valve is a rare congenital cardiac anomaly with an incidence of 0.008% to 0.043%. Its clinical course varies depending on cusp anatomy, function, and associated cardiac malformations. It frequently progresses to aortic valve regurgitation that may require surgical valve replacement. Detection has shifted from incidental discovery during autopsies or cardiac surgeries in the early 20th century to various cardiac imaging methods in recent decades. In addition to contributing to the literature, this report supports the use of transesophageal echocardiography more liberally to detect aortic valve abnormalities. The case presents a 48-year-old female patient with an incidentally discovered quadricuspid aortic valve.

Background: Ulcerative colitis (UC) is a chronic inflammatory colon disease characterized by relapsing flares and remission episodes. However, the optimal steroid tapering strategy in patients hospitalized for acute severe UC (ASUC) remains relatively unknown. We aim to examine the clinical outcomes in patients hospitalized for ASUC regarding variable prednisone taper regimens upon discharge. Methods: We retrospectively reviewed all adult patients admitted to our facility with ASUC between 2000 and 2022. Patients were divided into 2 groups based on the duration of steroid taper on discharge (<â 6 andâ >â 6 weeks). Patients who had colectomy at index admission were excluded from the analysis. The primary outcome was rehospitalization for ASUC within 6 months of index admission. Secondary outcomes included the need for colectomy, worsening endoscopic disease extent and/or severity during the follow-up period (6 months), and a composite outcome as a surrogate of worsening disease (defined as a combination of all products above). Two-sample t-tests and Pearson's chi-square tests were used to compare the means of continuous and categorical variables, respectively. Multivariate logistic regression analysis was performed to identify independent predictors for rehospitalization with ASUC. Results: A total of 215 patients (short steroid taperâ =â 91 and long steroid taperâ =â 124) were analyzed. A higher number of patients in the long steroid taper group had a longer disease duration since diagnosis and moderate-severe endoscopic disease activity (63.8 vs. 25.6 months, pâ <â 0.0001, 46.8% vs. 23.1%, P =â ≤â .05, respectively). Both groups had similar disease extent, prior biologic therapy, and the need for inpatient rescue therapy. At the 6-month follow-up, rates of rehospitalization with a flare of UC were comparable between the 2 groups (68.3% vs. 68.5%, Pâ =â .723). On univariate and multivariate logistic regression, escalation of steroid dose within four weeks of discharge (aOR 6.09, 95% CI: 1.82-20.3, P â =â .003) was noted to be the only independent predictor for rehospitalization with ASUC. Conclusions: This is the first study comparing clinical outcomes between post-discharge steroid tapering regimens in hospitalized patients for ASUC. Both examined steroid taper regimens upon discharge showed comparable clinical results. Hence, we suggest a short steroid taper as a standard post-hospitalization strategy in patients following ASUC encounters. It is likely to enhance patient tolerability and reduce steroid-related adverse effects without adversely affecting outcomes.
RESUMEN
Lung transplant recipients are at higher risk of developing COVID-19 infection compared to other solid organ transplants. The risk further increases in the unvaccinated patients. We present a case of a 43-year-old male who underwent bilateral sequential lung transplantation for pulmonary alveolar microlithiasis (PAM) and had an uneventful recovery. However, two years post-transplantation, the patient developed chronic lung allograft dysfunction (CLAD) with bronchiolitis obliterans syndrome and two episodes of COVID-19 infection. During the second episode of COVID-19 infection, the patient developed sepsis and multi-organ dysfunction ultimately resulting in death. Our case report highlights the increased susceptibility of PAM patients' post-lung transplant to COVID-19 infection. Continuous follow-up of PAM patients' post-lung transplantation is necessary to prevent unfavorable outcomes.
