RESUMO
Functional mitral regurgitation (FMR) is the result of three-dimensional structural disruption of the mitral valve due to left ventricular dysfunction. The "edge-to-edge" surgical technique has given rise to the percutaneous transcatheter edge-to-edge repair (TEER) technique to treat FMR; however, the lack of a mitral annuloplasty ring makes TEER only partially effective, with uncertain long-term results. The MITRA-FR and COAPT trials, on which current TEER recommendations are based, show conflicting results. COAPT results possible bias has influenced current recommendations issued by clinical practice guidelines in favor of TEER in FMR.
La regurgitación valvular mitral funcional es el resultado de la desestructuración tridimensional de la válvula mitral debido a disfunción ventricular izquierda. La técnica quirúrgica de "borde a borde" ha dado lugar a la técnica transcatéter "borde a borde" percutánea (TEER) para tratar la regurgitación valvular mitral funcional; sin embargo, la falta de un anillo protésico por anuloplastia hace a la TEER solo parcialmente efectiva con resultados inciertos a largo plazo. Los estudios MITRA-FR (Multicentre Randomized Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients with Severe Secondary Mitral Regurgitation) y COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation), en los cuales están basadas las recomendaciones actuales de la TEER, muestran resultados contradictorios. El posible sesgo de los resultados del COAPT ha influido en las recomendaciones actuales emitidas en las guías de práctica clínica a favor de la TEER en regurgitación valvular mitral funcional.

Professional medical liability is the result of medical malpractice, which may be due to negligence, incompetence or carelessness. Lex Artis is the set of skills and knowledge that have been universally accepted by peers, which must be diligently applied in the specific situation of a given patient. Thus, Lex Artis is essentially everything contained in clinical practice guidelines. Judicially speaking, the practice of medicine in Mexico is an obligation of means, but not of results. Therefore, adherence to clinical practice guidelines recommendations is the most effective way to defend oneself against a malpractice lawsuit.
La responsabilidad médica profesional es el resultado de mala praxis médica, la cual puede deberse a negligencia, impericia o imprudencia. Se conoce como lex artis al conjunto de conocimientos y habilidades que han sido universalmente aceptados por los pares, los cuales deben ser diligentemente aplicados en la situación específica de un paciente determinado. Entonces, lex artis es fundamentalmente todo lo contenido en las guías para la práctica clínica. Judicialmente hablando, en México el ejercicio de la medicina es una obligación de medios, mas no de resultados. Por consiguiente, apegarse a las recomendaciones de las guías para la práctica clínica es más efectivo para defenderse de una demanda legal por mala praxis.

RESUMO
OBJECTIVE: To demonstrate that surgical removal of the left atrial appendage in patients with rheumatic mitral valve disease and long standing persistent atrial fibrillation decreases the possibility of stroke. This also removes the need for long-term oral anticoagulation after surgery. METHOD: A descriptive, prospective, observational study was conducted on 27 adult patients with rheumatic mitral valve disease and long standing persistent atrial fibrillation, who had undergone mitral valve surgery and surgical removal of the left atrial appendage. Oral anticoagulation was stopped in the third month after surgery. The end-point was the absence of embolic stroke. An assessment was also made of postoperative embolism formation in the left atrium using transthoracic echocardiography. RESULTS: None of the patients showed embolic stroke after the third post-operative month. Only one patient exhibited transient ischaemic attack on warfarin therapy within the three postoperative months. Left atrial thrombi were also found in 11 (40.7%) cases during surgery. Of these, 6 (54.5%) had had embolic stroke, with no statistical significance (P=.703). CONCLUSIONS: This study suggests there might be signs that the left atrial appendage may be the main source of emboli in rheumatic mitral valve disease, and its resection could eliminate the risk of stroke in patients with rheumatic mitral valve disease and long-standing persistent atrial fibrillation.
