Hemodynamic complications during transcatheter MitraClip repair in presence of congenital atrial septal defect
No full textTranscatheter edge-to-edge mitral valve repair with MitraClip System (Abbott Vascular, Menlo Park, CA) needs a trans-septal access for positioning the 22-Fr guiding catheter in the left atrium. To the best of our knowledge no data are currently available about the hemodynamic consequences of a congenital atrial septal defect (ASD) after MitraClip repair. We report a case of MitraClip repair in a patient with ostium secundum ASD and ischemic cardiomyopathy, who needed intraprocedural closure of the defect for serious hemodynamic complications, secondary to worsening of the right ventricular function, increased pulmonary pressure and inversion of the interatrial shunt in right-to-left direction. These events, which were exacerbated by high blood levels of PaCO2 for the anesthesiological protocol used, led to left-side low-output syndrome and cardiorespiratory arrest.

Percutaneous repair of mitral regurgitation: A new tool in the arsenal against heart failure?|Correzione percutanea dell'insufficienza mitralica: Un nuovo strumento nell'armamentario per lo scompenso cardiaco?
No full textMitral regurgitation (MR) is the second most common heart valve disease worldwide, requiring surgical intervention in Europe. The current gold-standard treatment is surgical repair or replacement. Despite clear international guidelines, many patients do not undergo surgical intervention due to comorbidities, real or perceived high risk for cardiac surgery. The treatment of patients with functional MR in advanced heart failure has unsatisfactory results in terms of long-term survival as shown by retrospective small surgical experiences even if there is weak evidence for beneficial effects on left ventricular remodeling and functional capacity. Nevertheless, the appropriateness and timing of valve surgery in patients with advanced heart failure remain controversial. Based on these results, the focus of research has shifted in recent years to the development of percutaneous approaches to treat severe MR, in order to restore valve function in a minimally invasive fashion. Currently, various percutaneous techniques are under investigation in clinical trials and others have been developed, based on the surgical principles of mitral valve repair. This article focuses on the percutaneous mitral valve repair procedure using the MitraClip system (Abbott Vascular, Abbott Park, Illinois, USA). This approach that reproduces the edge-to-edge technique described by Alfieri, is safe and effective in improving functional class and reducing rehospitalization rates for heart failure patients
Progression of Lactobacillus plantarum prosthetic valve endocarditis followed by transesophageal echocardiogram
No full textEndocarditis due to Lactobacillus species is extremely rare. We report an uncommon case of Lactobacillus plantarum bioprosthetic aortic valve endocarditis, presenting with severe aortic steno-regurgitation, which responded to conventional medical and surgical treatment. This case provides a better understanding of the disease process of L. plantarum and highlights the role of transesophageal echocardiography in following the entire course of endocarditis.

Late MitraClip procedure after left atrial appendage occlusion: Indication and procedure description
No full textWe report the first human case of percutaneous edge-to-edge mitral valve repair using MitraClip System (Abbott Vascular, Abbott Park, IL) in a patient, who previously underwent left atrial appendage closure with PLAATO System (ev3. Inc., Plymouth, MN). The procedure was successfully performed using the standard MitraClip technique, in the catheterization laboratory, with transesophageal echocardiographic and fluoroscopic guidance. We showed that a double percutaneous procedure for stroke prevention and mitral regurgitation treatment might be a valid approach in selected patients ineligible for chronic anticoagulation therapy and at high risk for conventional cardiac surgery.

Accessory aortic-valve tissue as a cause of severe aortic regurgitation: Intra-operative finding
No full textPeriprocedural anemia management in severe aortic stenosis patients undergoing transcatheter aortic valve implantation
No full textPreoperative anemia is a common finding in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI), and it has been shown to be associated with high mortality. The present review provides an overview of current management strategies of perioperative anemia in TAVI patients, including red blood cell transfusion, blood conservative protocol, iron supplementation, and erythropoietin administration. The goal is to recognize the treatable causes of anemia and treat them, in order to reduce transfusions and improve the outcome
