We studied the effectiveness of Radiofrequency (RF) modified maze in early and late restoration of sinus rhythm in patients with rheumatic heart disease (RHD). We studied 84 patients with RHD over 23.6±12.5 months after the RF modified maze and another group of 64 patients over six months after valvular surgery alone (the Non-Maze group). Any thromboembolic episodes and NYHA class of the patient were recorded. The short term survivors in sinus rhythm, underwent stress test and echocardiography for atrial transport function at 3–6 months after surgery. In the Maze group, sinus rhythm was restored in 60/70 patients (85.71%) immediately and sustained in 55/70 patients (78.57%) over the follow-up as against an immediate conversion rate of 5.3% (5/53 patients, p<0.001) in the Non-maze group. The additional Cardiopulmonary (CP) bypass time (p=0.13) and cross clamp time (p=0.511) needed for maze is not statistically significant. Left atrial (LA) transport function was preserved in 41/51 patients (80.4%) and Right atrial (RA) transport function in 51/51 patients (100%). Stress test showed good chronotropic response in all the 41 patients in whom it was performed. In the Maze group one patient presented with acute valve thrombosis and subsequently, succumbed to it. In the non maze group 3/55 patients (5.66%) were hospitalized for stroke. No patient needed permanent pacemaker nor was sinus node dysfunction seen. The immediate postoperative morbidity and mortality was comparable in the two groups. The RF modified maze is safe, effective and brief without any additional risk. It restores sinus rhythm in the majority, however there is an attrition in some. [ABSTRACT FROM AUTHOR] |
