Cardiac surgery in the morbidly obese.

Background: Obesity rates globally continue to rise and in turn the body mass index (BMI) of patients undergoing cardiac surgery is set to mirror this. Patients who are Class III obese (BMI ≥ 40) pose significant challenges to the surgical teams responsible for their care and are also at high risk of complications from surgery and even death. To improve outcomes in this population, interventions carried out in the preoperative, operative, and postoperative periods have shown promise.

Obesity and diabetes are major risk factors for epicardial adipose tissue inflammation.

BACKGROUNDEpicardial adipose tissue (EAT) directly overlies the myocardium, with changes in its morphology and volume associated with myriad cardiovascular and metabolic diseases. However, EAT's immune structure and cellular characterization remain incompletely described. We aimed to define the immune phenotype of EAT in humans and compare such profiles across lean, obese, and diabetic patients.

F-FDG PET/CT improves diagnostic certainty in native and prosthetic valve Infective Endocarditis over the modified Duke Criteria.

Background: International guidance recognizes the shortcomings of the modified Duke Criteria (mDC) in diagnosing infective endocarditis (IE) when transoesophageal echocardiography (TOE) is equivocal. F-FDG PET/CT (PET) has proven benefit in prosthetic valve endocarditis (PVE), but is restricted to extracardiac manifestations in native disease (NVE). We investigated the incremental benefit of PET over the mDC in NVE.

Clinical and echocardiographic predictors of decompensation in acute severe aortic regurgitation due to infective endocarditis.

Background: Patients with acute severe aortic regurgitation (AR) due to infective endocarditis can progress rapidly from the hemodynamically stable patient to pulmonary edema and cardiogenic shock. We sought to identify patients at risk of decompensation where emergent surgery should be undertaken.

Methods: We identified 90 patients with acute severe AR from the echocardiography laboratory database.

Coronary revascularisation in cardiac amyloidosis.

We present a case of coronary artery bypass grafting in a 78-year-old man with triple vessel disease and concomitant cardiac amyloidosis. Postoperatively, he developed a profound low cardiac output state and multiorgan failure. He died 3 weeks following surgery.

Postcardiotomy extracorporeal membrane oxygenation in a patient with Austrian syndrome.

A 43-year-old man with Austrian syndrome, the triad of infective endocarditis (IE), pneumonia and meningitis caused by , underwent emergency aortic and mitral valve replacement and closure of an aortic root abscess. Postoperatively, he required mechanical circulatory support with veno-arterial extracorporeal membrane oxygenation and an intra-aortic balloon pump. Several days after surgery, new mitral and aortic paraprosthetic leaks (PPLs) developed.

A systematic review and meta-analysis of endovascular versus open surgical repair for the traumatic ruptured thoracic aorta.

Objective: The purpose of this study was to compare clinical outcomes between open repair and thoracic endovascular aortic repair (TEVAR) in traumatic ruptured thoracic aorta.

Methods: A comprehensive search was undertaken of the four major databases (PubMed, Embase, Scopus, and Ovid) to identify all published data comparing open vs endovascular repair. Databases were evaluated to July 2018.

Infected calcified homograft root: a sutureless solution.

Aortic valve reoperation after homograft root implantation is high risk and may be technically challenging. Dense calcification of the annulus may prevent suture placement and often necessitates impromptu high-risk redo root replacement. Although transcutaneous aortic valve implantation is an attractive option in such scenarios, in the context of endocarditis it is contraindicated.
