Training Cardiac Surgeons: Safety and Requirements.

2021

To analyze whether cardiac surgical residents can perform their first surgeries without compromising patients' safety or outcomes, by comparing their performance and results to those of senior surgeons. All documented CABGs conducted between 2002 and 2020 were included. Surgeries were divided according to the experience level of the main surgeon (defined by the number of CABG conducted by him/her) using the following thresholds: 1000; 150; 80 and 35. This resulted in 5 groups: senior surgeons (the reference group); attending surgeons; fellow surgeons; advanced residents and new residents. Primary endpoint was 30 day mortality. Secondary endpoints included a list of intra and post-operative …

Short- and long-term outcomes for the surgical treatment of acute pulmonary embolism

2018

AbstractObjectivesAcute pulmonary embolism can be a life-threatening condition with a high mortality. The treatment choice is a matter of debate. The early and late outcomes of patients treated with surgical pulmonary embolectomy for acute pulmonary embolism in a single center were analyzed.MethodsAll consecutive patients operated on for pulmonary embolism between January 2002 and March 2017 were reviewed. Patient demographics and pre- and postoperative clinical data were retrieved from our patient registry, and risk factors for in-hospital and long-term mortality were identified.ResultsIn total, 175 patients (mean age 59±3 years, 50% male) were operated on for acute pulmonary embolism. In-…

Direct true lumen cannulation in type A acute aortic dissection: A review of an 11 years’ experience

2020

ObjectivesDirect true lumen cannulation (DTLC) of the aorta is an alternative cardiopulmonary bypass cannulation technique in the context of type A acute aortic dissection (A-AAD). DTLC has been reported to be effective in restoring adequate perfusion to jeopardized organs. This study reports and compares operative outcomes with DTLC or alternative cannulation techniques in a large cohort of patients with A-AAD.MethodsAll patients who underwent surgery for A-AAD between January 2006 and January 2017 in Mainz university hospital were reviewed. The choice of cannulation technique was left to the operating surgeon, however DTLC was our preference in patients who were in state of shock or showe…

Aortic remodelling after thoracic endovascular aortic repair in acute and chronic type B aortic dissections

2019

AbstractOBJECTIVESType B aortic dissections are routinely treated with thoracic endovascular aortic repair (TEVAR). The timing for TEVAR remains controversial and might have an impact on the remodelling capacity of the aorta. This study analyses and compares aortic remodelling in acute (ABD) and chronic (CBD) type B aortic dissections after TEVAR.METHODSThis retrospective study analysed the preoperative, postoperative and at least 1-year follow-up computed tomography of 53 TEVAR patients (36 ABD, 17 CBD) at a single institution between May 2005 and May 2016. The volumes of aortic lumen (AL), true lumen, false lumen (FL) and perfused FL were measured at the stent graft level (A), from the st…

Serum markers for early detection of patients with mesenteric ischemia after cardiac surgery

2018

AbstractObjectiveMesenteric ischemia (MESI) is a rare but often fatal complication in patients after cardiac surgery. Non-specific clinical symptoms and lack of specific laboratory parameters complicate the diagnosis. We evaluated potential serum markers for MESI in cardiac surgery patients.MethodsBetween March and October 2012, serial serum samples of 567 elective cardiac surgery patients were collected 1, 24, and 48 h after the operation, and concentrations of potential markers for MESI [α-glutathione-S-transferase (αGST), intestinal fatty-acid-binding protein (iFABP), and D-lactate] were measured retrospectively. In patients requiring laparotomy, blood samples obtained 72, 48, 24, and 12…

Survival and reinterventions after isolated proximal aortic repair in acute type A aortic dissection.

2018

OBJECTIVES Conventional treatment for acute type A dissection is the replacement of the ascending aorta. This study demonstrates the results of a conventional approach with isolated proximal repair combined with concomitant endovascular procedures. METHODS Replacement of the ascending aorta with or without an open distal anastomosis was defined as isolated proximal repair and was performed in 562/588 patients between January 2004 and June 2017. A total of 68% were DeBakey type I and 32% were DeBakey type II aortic dissections. Concomitant procedures were thoracic endovascular aortic repair (3.6%); visceral, renal and iliac stents (2%); and peripheral bypasses (1.1%). Mean follow-up was 4.6 …

Prediction of mortality rate in acute type A dissection: the German Registry for Acute Type A Aortic Dissection score.

2020

Abstract OBJECTIVES The goal was to develop a scoring system to predict the 30-day mortality rate for patients undergoing surgery for acute type A aortic dissection on the basis of the German Registry for Acute Type A Aortic Dissection (GERAADA) data set and to provide a Web-based application for standard use. METHODS A total of 2537 patients enrolled in GERAADA who underwent surgery between 2006 and 2015 were analysed. Variable selection was performed using the R-package FAMoS. The robustness of the results was confirmed via the bootstrap procedure. The coefficients of the final model were used to calculate the risk score in a Web-based application. RESULTS Age [odds ratio (OR) 1.018, 95% …
