ABSTRACT

Objective:

In this study, we aimed to compare clinical outcomes of superior transseptal approach with the conventional left atriotomy in patients undergoing mitral valve surgery.

Methods:

Between January 2010 and November 2012, a total of 91 consecutive adult patients (39 males, 52 females; mean age 54.0±15.4 years; range, 16 to 82 years) who underwent mitral valve surgery in the Division of Cardiovascular Surgery at Koşuyolu Training Hospital were included. The patients were randomized to either superior transseptal approach (n=47) or conventional left atriotomy (n=44). Demographic characteristics of the patients, comorbidities, additional interventions, intraoperational data, pre- and postoperative electrophysiological study findings, and postoperative complications were recorded.

Results:

Of all patients, 86.7% (n=79) were in New York Heart Association Class III, while 12 were in New York Heart Association Class IV. All patients underwent annuloplasty (42.9%) or valve replacement surgery (57.1%). There was no significant difference in pre- and postoperative electrocardiogram findings between the groups. Change from baseline in the cardiac rhythm was statistically significant in superior transseptal approach group alone (P<0.001). There was no statistically significant difference in mortality rate between the groups. Permanent pacemaker implantation was performed in 10.6% of the patients in superior transseptal approach group and 4.5% in the conventional left atriotomy group. No statistically significant difference in bleeding, total length of hospital and intensive care unit stay, the presence of low cardiac output syndrome was observed between the groups.

Conclusion:

Our study results suggest that superior transseptal approach does not lead to serious or fatal adverse effects on sinus node function or atrial vulnerability, compared to conventional approach. .
RESUMO

Objetivo:

O objetivo deste estudo é comparar os resultados clínicos da abordagem septal superior com a atriotomia esquerda convencional em pacientes submetidos à cirurgia valvar mitral.

Métodos:

Entre janeiro de 2010 e novembro de 2012, foi incluído um total de 91 pacientes adultos consecutivos (intervalo de 16 a 82 anos, média 54,0±15,4 anos; 39 homens, 52 mulheres) submetidos à cirurgia valvar mitral no Serviço de Cirurgia Cardiovascular no Hospital Training Koşuyolu. Os pacientes foram randomizados para abordagem septal superior (n=47) ou atriotomia esquerda convencional (n=44). Foram registradas características demográficas dos pacientes, comorbidades, intervenções adicionais, dados intraoperatórios, achados do estudo eletrofisiológico pré e pós-operatório e complicações pós-operatórias.

Resultados:

Do total de pacientes, 86,7% (n=79) estavam na Classe III e 12 na Classe IV da New York Heart Association. Todos os pacientes foram submetidos à anuloplastia (42,9%) ou cirurgia de troca valvar (57,1%). Não houve diferença significativa nos resultados do eletrocardiograma pré e pós-operatórios entre os grupos. Mudança da linha de base no ritmo cardíaco foi estatisticamente significativa apenas no grupo abordagem septal superior (P<0,001). Não houve diferença estatisticamente significativa na taxa de mortalidade entre os grupos. Marca-passo definitivo foi implantado em 10,6% dos pacientes no grupo abordagem septal superior e em 4,5% dos pacientes no grupo atriotomia esquerda convencional. Não houve diferença estatisticamente significativa no sangramento, tempo total de internação e de permanência na UTI, tendo sido observada síndrome de baixo débito cardíaco entre os grupos.

Conclusão:

Nossos resultados sugerem que a ...
