RESUMEN
OBJECTIVE:To compare the 1-year outcomes of complete percutaneous approach versus surgical vascular approach for transfemoral transcatheter aortic valve implantation (TAVI), among "real-world" patients from the multi-center Brazilian TAVI registry.BACKGROUND:Vascular access still remains a major challenge for TAVI via transfemoral approach. Vascular accessthrough complete percutaneous approaches or through open surgical vascular techniques seems to be acutely similar. However, the long-term outcomes of both techniques remain poorly described.METHODS:The study population comprised all patients treated via transfemoral route in the Brazilian TAVI registry, a "real-world", nation-based, multi-center study. Patients were divided according to the initial vascular access approach (percutaneous vs. surgical) and clinically followed-up for 1 year. The primary endpoint was the incidence of combined adverse events all-cause mortality, life-threatening bleeding, and/or major vascular complication at 1 year.RESULTS:A total of 402 patients from 18 centers comprised the study population (percutaneous approach in 182 patients; surgical cutdown approach 220 patients). The incidence of combined adverse events was not different in thepercutaneous and the surgical groups at 30 days (17.6% vs. 16.3%; P = 0.8) and at 1 year (primary endpoint) (30.9% vs. 28.8%; P = 0.8). Also, the study groups overall were comparable regarding the incidence of each individual safety adverse events at 30 days and at 1 year.CONCLUSION:Total percutaneous techniques or surgical cutdown and closure may provide similar safety and effectiveness during the first year of follow-up in patients undergoing transfemoral TAVI.

During the performance of an angiotecnich in a human heart, to highlight the coronary circulation, weobserved the presence of myocardial bridges in the anterior and medial branches of the left coronary artery, inthis heart was also demonstrated the presence of an artery trifurcation left coronary branches that originatedthe anterior interventricular, circumflex and median. Myocardial bridges are intriguing entities that do notalways show signs and symptoms, the presence of the median artery in hearts with myocardial bridges, is oneof the factors that may explain the absence of signs and symptoms in some patients with this entity. Moreoverthe myocardial bridges can explain the signs and symptoms of ischemia on functional testing.

A 75-year old woman with obstructive hypertrophic cardiomyopathy and class IV dyspnea refractory to medical management had relative contraindications for both pacemaker implantation and surgical approach. Percutaneous intervention was devised to perform the selective injection of absolute alcohol in the first septal branch of the left anterior descending coronary artery. This led to a limited septal infarction documented by ST elevation, enzymatic elevation and the appearance of complete right bundle branch block on the electrocardiogram. A baseline left ventricular outflow tract pressure gradient of 66mmHg was immediately abolished and no unexpected complications supervened. Currently, two months after the procedure, marked symptomatic relief is present and associated with the absence of obstructive outflow gradient, as documented by echocardiography.

Mulher de 75 anos com cardiomiopatia hipertrófica obstrutiva, com dispnéia classe IV, refratária ao tratamento clínico, apresentava contra-indicaçöes relativas para abordagens cirúrgica e de implante de marcapasso. Realizou-se procedimento intervencionista para injeçäo seletiva de álcool absoluto no 1§ ramo septal da artéria interventricular anterior. O infarto septal provocado acompanhou-se de liberaçäo enzimática, elevaçäo de ST e bloqueio de ramo direito do feixe de His. Näo houve complicaçöes inesperadas, e o gradiente da via ejetiva de ventrículo esquerdo, de 66mmHg, foi imediatamente abolido. Controle ecocardiográfico evidencia manutençäo desse resultado, até o momento, dois meses após o procedimento, em correspodência a marcante alívio sintomático.
