Intraoperative Dexmedetomidine Use for Enhanced Recovery after Surgery (ERAS) in Cardiac Surgery-Single Center Retrospective Observational Cohort Study.

: Dexmedetomidine, an alpha-2 agonist, is used as an adjunct to anesthesia in enhanced recovery after surgery (ERAS) programs. One of its advantages is the opioid-sparing effect which can facilitate early extubation and recovery. When the ERAS cardiac society was set in 2017, our facility was already using the ERAS program, in which the "fast-track Anesthesia" was facilitated by the intraoperative infusion of dexmedetomidine.

Thromboaspiration of a left-sided bioprosthetic valve thrombosis by a mini-access: the Lausanne novel procedure.

Left-sided bioprosthesis valve thrombosis (LSBVT) is a challenging complication necessitating invasive interventions. In this study, we introduce a novel, minimally invasive approach. We used a cerebral embolic protection system and an Occlutech cannula connected to an extracorporeal circuit, providing safer thrombus aspiration compared to the AngioVac system.

Implementation of cardiac enhanced recovery after surgery at Lausanne University Hospital, our roadbook to certification.

Objectives: Enhanced recovery after surgery (ERAS) is a multidisciplinary, patient-centred approach aimed at expediting recovery, improving clinical outcomes, and reducing healthcare costs. Initially developed for colorectal surgery, ERAS principles have been successfully applied across various surgical specialties, including cardiac surgery. This study outlines the implementation and certification process of the ERAS program in a tertiary cardiac surgical centre within the Heart-Vessel Department at Lausanne University Hospital.

Outcomes and Safety of Transcaval Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-analysis.

Background: The transcaval (TCv) vascular approach is increasingly used in transcatheter aortic valve replacement (TAVR) in patients unsuitable for the gold-standard transfemoral approach. We aimed to evaluate the efficacy, safety, and clinical outcomes associated with TCv-TAVR.

Methods: A systematic review and meta-analysis was conducted by searching PubMed/Medline, Embase, and the Cochrane Library for all articles assessing the TCv approach published through December 2023.

A study of ChatGPT in facilitating Heart Team decisions on severe aortic stenosis.

Background: Multidisciplinary Heart Teams (HTs) play a central role in the management of valvular heart diseases. However, the comprehensive evaluation of patients' data can be hindered by logistical challenges, which in turn may affect the care they receive.

Aims: This study aimed to explore the ability of artificial intelligence (AI), particularly large language models (LLMs), to improve clinical decision-making and enhance the efficiency of HTs.

Thrombocytopenia among Patients Undergoing Aortic Valve Replacement Using the Sutureless Perceval S Bioprosthesis: A Retrospective Study.

Background: The sutureless Perceval S bioprosthesis is associated with postoperative thrombocytopenia. Our objectives were to compare the incidence, severity, and clinical implications of thrombocytopenia after aortic valve replacement (AVR) using the Perceval S or the Trifecta bioprosthesis.

Methods: Patients who underwent AVR between March 2016 and August 2019 using the Perceval or Trifecta were retrospectively included.

Transcaval versus Supra-Aortic Vascular Accesses for Transcatheter Aortic Valve Replacement: A Systematic Review with Meta-Analysis.

A growing body of evidence suggests that extrathoracic vascular accesses for transcatheter aortic valve replacement (TAVR) yield favorable outcomes and can be considered as primary alternatives when the gold-standard transfemoral access is contraindicated. Data comparing the transcaval (TCv) to supra-aortic (SAo) approaches (transcarotid, transsubclavian, and transaxillary) for TAVR are lacking. We aimed to compare the outcomes and safety of TCv and SAo accesses for TAVR as alternatives to transfemoral TAVR.

Topical skin adhesive PRINEO as the ideal wound closure system in cardiac surgery to limit surgical site infection.

Objective: Surgical site infections (SSIs) are a major source of morbidity after cardiac surgery, involving prolonged hospitalisation. Among the numerous techniques of skin closure and dressings available, the optimal method remains undetermined. The DERMABOND-PRINEO (PRINEO) (PRINEO, Ethicon, J&J) is the only skin closure system which combines a topical skin adhesive with a mesh.

Transcatheter Aortic Valve Implantation Using the Transcervical Vascular Access (from a 7-Year Experience from a Swiss Tertiary Center).

The gold-standard transfemoral (TF) access for transcatheter aortic valve implantation (TAVI) is not suitable in 10% to 15% of patients, and alternative accesses are needed. Studies have suggested that the transcervical (TC) access might yield outcomes comparable to the TF access. In our center, TC-TAVI is the first-line alternative to TF-TAVI.

How to Solve the Conundrum of Heparin-Induced Thrombocytopenia during Cardiopulmonary Bypass.

Heparin-induced thrombocytopenia (HIT) is a major issue in cardiac surgery requiring cardiopulmonary bypass (CPB). HIT represents a severe adverse drug reaction after heparin administration. It consists of immune-mediated thrombocytopenia paradoxically leading to thrombotic events.

Vasoplegic Syndrome after Cardiopulmonary Bypass in Cardiovascular Surgery: Pathophysiology and Management in Critical Care.

Vasoplegic syndrome (VS) is a common complication following cardiovascular surgery with cardiopulmonary bypass (CPB), and its incidence varies from 5 to 44%. It is defined as a distributive form of shock due to a significant drop in vascular resistance after CPB. Risk factors of VS include heart failure with low ejection fraction, renal failure, pre-operative use of angiotensin-converting enzyme inhibitors, prolonged aortic cross-clamp and left ventricular assist device surgery.

Venoarterial Extracorporeal Membrane Oxygenation in High-Risk Pulmonary Embolism: A Case Series and Literature Review.

Background: High-risk Pulmonary Embolism (PE) has an ominous prognosis and requires emergent reperfusion therapy, primarily systemic thrombolysis (ST). In deteriorating patients or with contraindications to ST, Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) may be life-saving, as supported by several retrospective studies. However, due to the heterogeneous clinical presentation (refractory shock, resuscitated cardiac arrest (CA) or refractory CA), the real impact of VA-ECMO in high-risk PE remains to be fully determined.

Has the profile of heart transplantation recipients changed within the last three decades?

Background: Heart transplantation remains the most durable treatment for patients with end-stage heart failure refractory to medical treatment. Central elements of the listing criteria for heart transplantation have remained largely unchanged in the last three decades whereas treatment of heart failure has significantly increased survival and reduced disease-related symptoms. It remains unknown whether the improvement of heart failure therapy changed the profile of heart transplantation candidates or affected post-transplant survival.

Challenges in Patient Blood Management for Cardiac Surgery: A Narrative Review.

About 15 years ago, Patient Blood Management (PBM) emerged as a new paradigm in perioperative medicine and rapidly found support of all major medical societies and government bodies. Blood products are precious, scarce and expensive and their use is frequently associated with adverse short- and long-term outcomes. Recommendations and guidelines on the topic are published in an increasing rate.

Case Report: Are We Witnessing an Increase of Chronic Ascending Aortic Dissection as a Collateral Effect to the COVID-19 Pandemic?

The COVID-19 (coronavirus disease 2019) pandemic is reducing health care accessibility to non-life-threatening diseases, thus hiding their real incidence. Moreover, the incidence of potentially fatal conditions such as acute type A aortic dissection seems to have decreased since the pandemic began, whereas the number of cases of chronic ascending aortic dissections dramatically increased. We present two patients whose management has been affected by the exceptional sanitary situation we are dealing with.

Prosthetic Valve Endocarditis after Transcatheter Aortic Valve Implantation Complicated by Paravalvular Abscess and Treated by Pericardial Patches and Sutureless Valve Replacement.

Background: Endocarditis is a rare complication of transcatheter aortic valve implantation (TAVI), with an estimated 1-year incidence of 0.50% [Circulation 2015]. However, ensuing consequences are often dire, and its surgical treatment poses unique problems, due to the frequent underlying frailty of TAVI recipients.
