Transareolar Robotic-Assisted Access to the Mitral Valve.

During the past years, a rapid development and refinements of robotic heart valve techniques have led to consider robotic mitral valve (MV) surgery safe, effective, and durable. Robotic MV surgery has proven to be a cost-effective and cost-saving strategy in MV operations, being associated with reduced morbidity and mortality rates. We present a novel video-assisted transareolar approach to access the MV using the da Vinci Si HD telemanipulation system (Intuitive Surgical, Inc, Sunnyvale, CA USA). This technique is effective and reproducible, providing maximum patient satisfaction from both the clinical and cosmetic points of view.

The minithoracotomy approach: a safe and effective alternative for heart valve surgery.

Despite criticisms over the last decade, heart valve surgery through right anterior minithoracotomy (MT) proved excellent short-term and long-term-term results, becoming a feasible and popular alternative to the sternotomy approach. The rapid development and refinements of techniques have led to MT valve surgery being considered safe, effective, and durable. Minithoracotomy has been demonstrated to be a valid cost-effective and cost-saving strategy for valve surgery, being associated with reduced morbidity and mortality. Tangible benefits include less pain, faster postoperative recovery, and better cosmetic results. As a result, MT has been increasingly used as a routine approach in many centers for both aortic and mitral valve surgery.

Leukocyte depletion during extracorporeal circulation allows better organ protection but does not change hospital outcomes.

BACKGROUND: Leukocyte filtration has been reported to reduce inflammatory damage during cardiopulmonary bypass. We evaluated the role of leukocyte filtration on hospital outcome and postoperative morbidity. METHODS: Eighty-two consecutive patients who underwent isolated coronary artery bypass grafting were randomly assigned (1:1) to receive leukocyte filters on both arterial and cardioplegia lines or standard arterial filters during cardiopulmonary bypass. Hospital outcome, postoperative markers of morbidity, and biochemical assays were compared. Data were collected preoperatively, intraoperatively, and postoperatively. Costs for patients receiving intraoperative leukofiltration were compared with control patients getting standard arterial filters. RESULTS: Hospital mortality and intensive care unit and hospital length of stay were similar. Although duration of ventilation and incidence of pneumonia were comparable, leukocyte-depleted patients showed a higher ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (p = 0.008) and lower need for postoperative noninvasive ventilation (p = 0.041). Control patients showed higher need for continuous furosemide infusion (p = 0.013) and for renal replacement therapy (p = 0.014), in association with higher serum creatinine (p = 0.038) and blood urea (p = 0.18) and lower glomerular filtration rate (p = 0.038). Leukocyte-depleted patients required lower doses of inotropic agents (p = 0.56), whereas troponin I leakage and incidence of postoperative atrial fibrillation were comparable. No differences were found in terms of postoperative cerebral dysfunction or neutrophil and platelet counts, as well as postoperative bleeding and need for transfusions. Finally, leukodepletion proved significantly cost-beneficial, with a 37% cost reduction. CONCLUSIONS: Although hospital outcomes were similar in terms of mortality and length of stay, the improvements in pulmonary, renal, and myocardial function, in association with the cost benefit, justify the use of leukocyte-depletion filters in the clinical practice.

Asymptomatic cardiac papillary fibroelastoma: diagnostic assessment and therapy.

Papillary fibroelastoma is a rare benign cardiac tumor with elevated risk for embolization. This report describes the case of a 65-year-old man, admitted for the occasional finding of a round, pedunculate mass adherent to the chordae of the anterior mitral valve leaflet, mimicking an endocarditic mass. Appropriate diagnostic evaluations lead to the suspect of a papillary fibroelastoma. Because of the elevated risk of thromboembolism, surgery was emergently performed with complete removal of the mass and preservation of the integrity of the mitral valve. Histologic evaluation confirmed the diagnosis. Papillary fibroelastoma should be always considered in the differential diagnosis of intracardiac masses.
