Valve Replacement Surgery

Objectives: To evaluate results of minimally invasive aortic valve replacement surgery through right thoracotomy with some techinque improvements in Hanoi Heart Hospital. Methods: Surgery was performed via a small right thoracotomy in the second intercostal space. The third rib was detached by a wedge-shaped way using sternum saw. Cannulation approaches were central or peripheral depended on patients’ condition. Preoperative, perioperative, early results and follow-up data was collected and analysed. Results: There was 48 patients in the research. Mean age was 60,94 ± 11,53 (25-82), and 52,1% was male. 29,2% of patients had peripheral vascular disease. 22,9% underwent central arterial cannulation. 3 patients (6,3%) had pericardial adhesion. There was no early mortality, 2 patients had redo surgery due to excess bleeding. 1 patients had intestinal infarction. Mean follow-up time was 13,4 months. 91,3% of patients had NYHA I. 1 patients was dead due to intracerebral hemorrhage. Conclusions: With some improvements in techniques, minimally invasive aortic valve replacement surgery through right thoracotomy gave good early and midterm results in our center.

ObjectiveMinimally invasive aortic valve replacementsurgery (MIAVR) is an alternative surgical technique to conventional aortic valve replacement surgery (AVR) in selected patients. The randomised study Cardiac Function after Minimally Invasive Aortic Valve Implantation (CMILE) showed that right ventricular (RV) longitudinal function was reduced after both MIAVR and AVR, but the reduction was more pronounced following AVR. However, postoperative global RV function was equally impaired in both groups. The purpose of this study was to explore alterations in RV mechanics and contractility following MIAVR as compared with AVR.MethodsA predefined post hoc analysis of CMILE consisting of 40 patients with severe aortic valve stenosis who were eligible for isolated surgical aortic valve replacement were randomised to MIAVR or AVR. RV function was assessed by echocardiography prior to surgery and 40 days post-surgery.ResultsComparing preoperative to postoperative values, RV longitudinal strain rate was preserved following MIAVR (−1.5±0.5 vs −1.5±0.4 1/s, p=0.84) but declined following AVR (−1.7±0.3 vs −1.4±0.3 1/s, p<0.01). RV longitudinal strain reduced following AVR (−27.4±2.9% vs −18.8%±4.7%, p<0.001) and MIAVR (−26.5±5.3% vs −20.7%±4.5%, p<0.01). Peak systolic velocity of the lateral tricuspid annulus reduced by 36.6% in the AVR group (9.3±2.1 vs 5.9±1.5 cm/s, p<0.01) and 18.8% in the MIAVR group (10.1±2.9 vs 8.2±1.4 cm/s, p<0.01) when comparing preoperative values with postoperative values.ConclusionsRV contractility was preserved following MIAVR but was deteriorated following AVR. RV longitudinal function reduced substantially following AVR. A decline in RV longitudinal function was also observed following MIAVR, however, to a much lesser extent.
