Novel Use of the Perceval Valve for Prosthetic Aortic Valve Endocarditis Requiring Root Replacement

The surgical management of aortic valve endocarditis can be challenging. Infection with abscess formation can destroy the root and annulus, making it difficult to anchor a valve conduit. In this article, we present a novel and efficient strategy for proximal aortic reconstruction. We used a Dacron tube graft and anchored it proximally with a running suture line deep in the left ventricular outflow tract. The coronary buttons were attached, and a Perceval valve was then deployed inside the neo-root to create a bio-Bentall.

A Reproducible and Effective Technique for Coronary Sinus Injury Repair

Objective: Coronary sinus injury related to the use of a retrograde cardioplegia catheter is a rare but potentially life-threatening complication with mortality reported as high as 20%. We present a series of iatrogenic coronary sinus injuries as well as an effective method of repair without any ensuing mortality. Methods: There were 3,004 cases that utilized retrograde cardioplegia at our institution from 2007 to 2018. Of these, 15 patients suffered a coronary sinus injury, an incidence of 0.49%. A pericardial roof repair was performed in 14 cases in which autologous pericardium was sutured circumferentially to normal epicardium around the injury with purified bovine serum albumin and glutaraldehyde injected into the newly created space as a sealant. Incidence of perioperative morbidity and mortality, operative time, and length of stay were collected. Results: In our series, there were no intraoperative or perioperative mortalities. Procedure types included coronary artery bypass grafting (CABG), valve replacement and repair, or combined CABG and valve procedures. Median (interquartile range) cross-clamp time was 100 (88 to 131) minutes, cardiopulmonary bypass duration was 133 (114 to 176) minutes, and length of stay was 6 (4 to 8) days. None of the patients returned to the operating room for hemorrhage, and there were no complications associated with the repair of a coronary sinus injury when using the pericardial roof technique. Conclusions: Coronary sinus injuries can result in difficult to manage perioperative bleeding and potentially lethal consequences from cardiac manipulation. Our series supports the pericardial roof technique as an effective solution to a challenging intraoperative complication.

Emergency Endovascular Total Arch Exclusion With an Off-the-Shelf Bimodular Device

A patient with a history of surgery for type A acute aortic dissection was readmitted for aortic arch and descending aortic dissection with rupture at the isthmus and periaortic hematoma. Due to the high surgical risk, the aortic team chose an endovascular approach, and the patient successfully underwent emergency total arch exclusion with an off-the-shelf, bimodular, single-branch device. The main module was deployed in the aortic arch and in the brachiocephalic trunk, and the second module was deployed in the ascending aorta. Despite the good perioperative outcome with no cerebrovascular events, the patient died 20 days later because of sudden iliac rupture.

Video-Assisted Thoracoscopic Surgical Rib Fixation for Costochondral Separation Injury

Costochondral separation is a rare phenomenon following blunt thoracic trauma that can also be associated with secondary injuries. We present a case with complete costochondral separation of the right second rib with concomitant mediastinal compression. Definitive treatment was provided through video-assisted thoracoscopic surgical plate osteosynthesis.

Can Patients Travel by Air Less Than 1 Week After Lung Nodulectomy?

Objective: The study objective was to determine empirically based timing recommendations for safe air travel following lung nodulectomy. Methods: All patients who underwent pulmonary nonanatomic resection followed by air travel home immediately after discharge were identified at 2 institutions between 2014 and 2018. These patients were surveyed via telephone regarding any complications they may have experienced during their travel home and within the first week after discharge. These complications included shortness of breath, chest pain, drainage from their surgical sites, and evaluation by a health care provider in the interim, if they required. Results: Our study identified 27 patients who fit the inclusion criteria. The median number of days between surgery and flight home in the studied population was 4 days. The median number of days between chest tube removal and flight home was 2 days. None of the 27 patients reported experiencing shortness of breath, chest pain, drainage from their surgical sites, or need for evaluation by a health care provider within 1 week of discharge. Nine patients (33%) traveled by air with a small (<5%) pneumothorax documented on chest radiography after removal of thoracostomy tube. One (4%) patient successfully traveled without complication with a 10% pneumothorax. Conclusions: The findings of our study support the safety of air travel following lung nodulectomy in patients who have undergone uneventful wedge resection and have no significant pulmonary or cardiac comorbidities. It is not necessary for patients to wait the recommended 7 days prior to traveling.

Use of Mobile-Based Application for Collection of Patient-Reported Outcomes in Cardiac Surgery

Objective Application-based (app) technology has been studied for patient engagement and collecting patient-reported outcomes (PROs) in several surgical specialties with limited research in cardiac surgery. The aim of study was to determine the effectiveness of app-based technology for collecting PROs, improving the patient experience, and reducing health services utilization in a cardiac surgery center. Methods Patients accessed an interactive app via smartphones. Patients were guided from 4 weeks preoperative to 4 weeks postoperative via reminders, tasks, PRO surveys, and evidence-based education. In the postoperative period, patients were engaged with daily health surveys to track warning signs and recovery milestones. Based on the patient's signs and symptoms, the app escalated lower risk issues to self-care education or higher risk issues to the care team (e.g., phone call to a nurse). Results Sixty-six percent of patients (730 of 1,108) activated their app account. Two hundred seventy-seven patients completed an end-of-program feedback survey, with 94% of patients recommending the app and 98% of patients finding the app was helpful in recovery. Patients also reported using the app to avoid unnecessary health services utilization, with 45% of patients using the app to avoid at least 1 phone call and 28% of patients using the app to avoid at least 1 hospital visit. Conclusions App-based technology for patient engagement is an effective modality to enhance the patient experience, better understand the trajectory of recovery, and reduce unnecessary health services utilization in cardiac surgery.

How We Perform a David Procedure With an Upper Hemisternotomy Approach

Objective Valve-sparing aortic root replacement (David procedure) is the technique of choice in appropriately selected patients with aortic root aneurysms. These procedures are seldom performed in a minimally invasive fashion. We describe our systematic approach to the David procedure using an upper hemisternotomy (UHS). Methods: Our method involves a J-type UHS exiting the right third or fourth intercostal space. Ascending aortic and femoral venous cannulation are performed using the Seldinger technique under transesophageal echocardiographic guidance. Between August 2005 and August 2014, 27 patients underwent an isolated elective David procedure using a full sternotomy (FS). Sixteen underwent an isolated elective UHS David procedure from May 2015 to February 2019. Perioperative safety outcomes were compared between the 2 cohorts. Results: The UHS and FS David cohorts were primarily male (87.5% and 85.2%, respectively) and 51 and 50 years old on average, respectively. Custodiol-histidine-tryptophan-ketoglutarate cardioplegia (93.8% vs 37.0%, P < 0.001) and Cor-Knot (100% vs 0%, P < 0.001) were used significantly more in the UHS David cohort. There were no significant differences in cardiopulmonary bypass (200 [183–208] vs 212 [183–223] min, P = 0.309) and aortic cross-clamp (169 [155–179] vs 188 [155–199] min, P = 0.128) times in the UHS and FS cohorts. There were no instances of hospital or 30-day mortality in either cohort. Intensive care unit and hospital stays were comparable between the 2 cohorts. Conclusions: The David procedure via UHS is a safe and reproducible technique for aortic root replacement.
