Patient-prosthesis mismatch has no influence on in-hospital mortality after aortic valve replacement.

OBJECTIVE: To analyze the relationship between prosthetic aortic valve orifice and body surface area (Effective Orifice Area Index, EOAI) and in-hospital mortality after aortic valve replacement. MATERIAL AND METHOD: A prospective study was conducted between October 2007 to September 2010, 536 patients underwent isolated aortic valve replacement (AVR) was recorded on preoperative, operative and postoperative data. Patient Prosthesis Mismatch (PPM) was classified by Effective Orifice Area Indexed (EOAI) by prosthetic valve area divided by body surface area as mild or no significance if the EOAI is greater than 0.85 cm2/m2, moderate if between 0.65 cm2/m2 and 0.85 cm2/m2, and severe if less than 0.65 cm2/m2. Statistical differences were analyzed by Chi-square and student t-test with p-value less than 0.05 considered significant. RESULTS: There were 304 men, mean age was 60.98 years, mean valve orifice area 1.69 cm2, body surface area 1.60 m2, cross clamp time 1.13 hrs., bypass time 1.67 hrs. Mechanical valves were used in 274 patients (51.2%) and Bioprosthesis were used in 181 patients (48.8%). PPM was found in 33.7%, 6.7% was severe PPM, 27% was moderate PPM and 66.3% has no significant PPM Over all in-hospital mortality was 1.5%. There was no significant difference in hospital mortality between no PPM group, moderate PPM and severe PPM group (1.4% vs. 1.4% vs. 5.4%, p-value = 0.86). CONCLUSION: In a large aortic valve surgery population, moderate and severe patient prosthesis mismatch occurred in 35.6% of patients but had no influence on in-hospital mortality.

Current Perspectives on Contemporary Rheumatic Mitral Valve Repair.

The surgical management of rheumatic mitral valve disease remains a challenge for cardiac surgeons. Durability of mitral valve repair (MVr) is likely compromised not simply due to high technical demand, but surgeon reluctance, despite boasting copious advantages over MV replacement. This comprehensive review aims to evoke a deeper understanding of MVr concepts necessary to abate these limitations and shift mindset towards a more holistic approach to repair. Details of commonly utilized techniques in contemporary MVr for rheumatic heart disease will be discussed. Of importance, the reparative procedures will be mapped to an in-depth physiological exploration of the mitral complex-dynamism and rheumatic interplay. This is further emphasized by outlining the current "aggressive" resection strategy in contemporary rheumatic MVr.

Rheumatic mitral valve repair: a physiologic and dynamic approach.

Rheumatic valve repair although complex but with better understanding of mitral complex and dynamics, successful rate of mitral repair is enhanced and promising.

Rheumatic mitral valve repair: a personal perspective and results.

Rheumatic mitral valve disease remains a challenge for cardiac surgeons. Valve repair has several advantages over valve replacement but is technically demanding for good results. To improve rheumatic mitral valve repair, surgeons need to have a deep understand of the mitral valve complex and its dynamics. The goal of repair is to restore normal diastolic and systolic function. The current approach is to perform a holistic repair of the entire mitral complex. Each part of the complex is thoroughly explored to define the problem. Several innovative techniques have been introduced to correct valve dysfunction and provide gratifying results. The details of these techniques will be described, based on an understanding of the relationship of the mitral valve complex and dynamics. With this approach, rheumatic mitral valve repair is becoming more successful, reproducible, and safe. Long-term follow-up is mandatory.

Autologous pericardial valved conduit for the Ross operation.

The feasibility and function of autologous pericardial valved conduit for right ventricular outflow tract reconstruction in the Ross operation were assessed. Between June 1997 and April 2002, 31 patients underwent this procedure at our institution; one was lost to follow-up. The other 26 males and 4 females were aged 17 to 60 years (mean, 36.6 years). Causes of aortic valve disease were infective endocarditis in 26 and rheumatic valve disease in 4. Mean follow-up was 16.7 months (range, 1-58 months). Preoperatively, 9 patients were in functional class II, 19 in class III, and 2 in class IV. Concomitant procedures included coronary artery bypass (1), mitral valve replacement (6), tricuspid valve replacement (1), and ventricular septal defect closure (1). Mean aortic crossclamp time was 199.4 min. There were 4 (13.3%) hospital deaths and no late death. Mean postoperative functional class was 1.17 with +0.36 aortic regurgitation, a peak gradient of 21.9 mm Hg (range, 6-59 mm Hg) across the conduit, and grade +0.96 pulmonary regurgitation. No conduit-related complication was detected. Use of autologous valved conduit for the Ross operation is feasible. Long-term follow-up is mandatory to assess durability.

Left atrial reduction in modified maze procedure with concomitant mitral surgery.

BACKGROUND: An association between mitral valve disease and atrial fibrillation is common. Modifications of energy sources have simplified surgical ablation. Left atrial size reduction should improve outcomes of the maze operation. METHODS: Between 2004 and 2011, 236 patients with permanent atrial fibrillation and mitral valve disease underwent mitral valve surgery and modified biatrial radiofrequency ablation. The study evaluated cardiac rhythm, atrial size, atrial contractility, and survival. RESULTS: The mitral valve was repaired in 88 (37.3%) patients and replaced in 148 (62.7%). The left atrium was reduced in 192 (81.4%) patients: 31 (13.1%) had posterior wall reduction and 161 (68.2%) had right lateral and posterior wall resection. The 30-day mortality was 4.2% (10/236). The median follow-up was 41 months. Actuarial freedom from atrial fibrillation at 1 year and last follow-up was 87.7% and 84.9%, respectively. Predictors of recurrence were preoperative left atrial diameter >60 mm (p = 0.002), postoperative diameter >50 mm (p < 0.001), atrial fibrillation on day 7 (p < 0.001), and technique of reduction (posterolateral/posterior) in patients with atrial size >60 mm (p = 0.017). Atrial fibrillation during follow-up (p = 0.002) and age >60 years (p = 0.003) were significant predictors of poorer survival. During 5-year follow-up, non-atrial fibrillation patients survived significantly longer than atrial fibrillation patients (p = 0.002). CONCLUSIONS: Radiofrequency ablation is an effective option for treatment of permanent atrial fibrillation concomitant with mitral valve surgery. Atrial reduction to <50 mm improves success. Elimination of atrial fibrillation significantly prolongs patient survival.
