Endomyocardial biopsy through the left internal jugular vein in heart transplant recipients: a single center experience.

Endomyocardial biopsies for rejection monitoring after heart transplantation are generally performed through the right internal jugular vein. We aimed to assess the feasibility and safety of using the left internal jugular vein approach as a valid alternative to a femoral vein for endomyocardial biopsies whenever thrombosis of the right internal jugular vein precludes insertion of a bioptome. We have reviewed our experience with heart transplantation in the last 2 decades to identify patients in whom surveillance endomyocardial biopsy was performed through the left internal jugular vein.

Artificial Neochordae for Tricuspid Valve Repair in Adults: A Review.

Expanded polytetrafluoroethylene (ePTFE) neochordae are predominantly used for mitral valve repair (MVr), while the frequency of their employment in tricuspid valve surgery is not well assessed. We have performed a review of the available literature to verify incidence, indications, techniques, and outcomes of the use of artificial neochordae in a variety of tricuspid valve pathologies. We found a total of 57 articles reporting the use of ePTFE sutures in patients in whom tricuspid valve repair (TVr) was performed.

Prognostic Value of APACHE IV Score in Patients Bridged to Heart Transplantation on ECMO.

Background: Methods for risk stratification of candidates for heart transplantation (HTx) supported by extracorporeal membrane oxygenation (ECMO) are limited. We evaluated the reliability of the APACHE IV score to identify the risk of mortality in this patient subset in a multicenter study.

Methods: Between January 2010 and December 2022, 167 consecutive ECMO patients were bridged to HTx; they were divided into two groups, according to a cutoff value of APACHE IV score, obtained by receiver operating characteristic curve analysis for 90-day mortality.

Milestone Operations in Heart Valve and Aortic Replacement: Anniversaries Worth Remembering.

Seventy years ago, in 1952, Charles A. Hufnagel implanted a caged-ball prosthesis into the descending thoracic aorta, to treat a patient with aortic valve insufficiency. In 1962, 60 years ago, the first aortic homograft was implanted in a subcoronary position by Donald N.

Metabolic Syndrome and Heart Transplantation: An Underestimated Risk Factor?

Metabolic Syndrome (MetS), a multifactorial condition that increases the risk of cardio-vascular events, is frequent in Heart-transplant (HTx) candidates and worsens with immunosuppressive therapy. The aim of the study was to analyze the impact of MetS on long-term outcome of HTx patients. Since 2007, 349 HTx patients were enrolled.

Influence of a regional network combined with a systematic multidisciplinary approach on the outcomes of patients with acute type A aortic dissection.

Background: Whether in patients with acute type A aortic dissection reduction of intervals between onset of symptoms and diagnosis influences patient outcomes is still not completely defined.

Methods: In 199 patients with acute type A aortic dissection, the efficacy of a systematic multidisciplinary approach and institution of a regional network were evaluated; 90 patients operated before 2016 (Group1) were compared with 109 repaired after 2016 (Group2) for early and late outcomes.

Results: Mortality was reduced from 13% in Group1 to 4% in Group2 (p = 0.

Heart Transplantation in High-Risk Recipients Employing Donor Marginal Grafts Preserved With Perfusion.

Extending selection criteria to face donor organ shortage in heart transplantation (HTx) may increase the risk of mortality. normothermic perfusion (EVP) limits ischemic time allowing assessment of graft function. We investigated the outcome of HTx in 80 high-risk recipients transplanted with marginal donor and EVP-preserved grafts, from 2016 to 2021.

Closed Mitral Valvotomy: Celebrating 100 Years of Surgical History.

The year 2023 marks the 100th anniversary of the first successful valvotomy for mitral valve stenosis by Elliott C. Cutler in 1923. Closed-chest mitral valve commissurotomy developed further before being replaced by an open procedure after the advent of the heart-lung machine.

Replacement of a Calcified Aortic Valve in a Porcine Aortic Root with the Perceval Sutureless Bioprosthesis.

We report a 79-year-old patient who had aortic valve replacement (AVR) using a porcine aortic root. Due to degeneration of the porcine aortic valve, he required reoperation during which a heavily calcified porcine root and aortic annulus prevented insertion of any traditional bioprosthesis. AVR was achieved using a sutureless bioprosthesis, combined with mitral valve replacement.

Artificial chordae for mitral valve repair.

Background: Mitral valve repair using expanded polytetrafluoroethylene sutures to replace mitral chordae tendineae is a well-established procedure. However, the incidence of neo-chordae failure causing recurrent mitral regurgitation is not well defined.

Methods: We have reviewed the reported cases of complications after mitral valve repair related to the use of neo-chordae.

Distal Reoperations after Repair of Acute Type A Aortic Dissection-Incidence, Causes and Outcomes.

Background And Aim Of The Study: In patients with acute type A aortic dissection (A-AAD) whether initial repair should include also aortic arch replacement is still debated. We aimed to assess if extensive aortic repair prevents from reoperations patients with A-AAD.

Methods: Outcomes after distal reoperation following repair of A-AAD (n = 285; 1977 to 2018) were analysed in 22 of 226 who underwent ascending aorta/hemiarch replacement (Group ) and 7 of 59 who had ascending aorta/arch replacement (Group ).

The Caged-Ball Prosthesis 60 Years Later: A Historical Review of a Cardiac Surgery Milestone.

Sixty years ago, 2 cardiac operations dramatically influenced the survival of patients with valvular heart disease. The replacement of an aortic valve by Dwight Harken and of a mitral valve by Albert Starr with mechanical caged-ball valves, both in 1960, was a true milestone in the history of cardiac surgery and the beginning of a long journey toward prosthetic valve replacement full of expectations, hopes, and dreams fulfilled. Caged-ball prostheses underwent numerous modifications in design and materials to improve reliability and prevent specific mechanical and thrombogenic complications.

Early awaking of patients following FET allows early recognition of paraplegia with prospects for complete recovery using prompt spinal drainage.

We report a patient who presented with paraplegia after ascending aorta and arch replacement using the frozen elephant trunk technique. Immediate postoperatively cerebrospinal fluid drainage allowed successful reversal of spinal cord injury. Early awakening of patients following a frozen elephant trunk technique is mandatory because it allows recognition and treatment of this complication by prompt cerebrospinal liquor drainage.

Endothelial Progenitor Cells: An Appraisal of Relevant Data from Bench to Bedside.

The mobilization of endothelial progenitor cells (EPCs) into circulation from bone marrow is well known to be present in several clinical settings, including acute coronary syndrome, heart failure, diabetes and peripheral vascular disease. The aim of this review was to explore the current literature focusing on the great opportunity that EPCs can have in terms of regenerative medicine.
