结论左肺动脉狭窄、肺动脉瓣反流和右心室扩大是TO F术后常见的并发症。
Conclusion Left pulmonary stenosis, pulmonary regurgitation and right ventricular enlargement are common complications after surgery for TOF.
但是在这个过程中，心脏出现了适应性改变：左、右心室扩大，从形态上开始与那些非运动员的心脏有了很大差异。
But in the process, the heart ADAPTS and changes. Its left and right ventricles enlarge. It begins to look quite different than a non-athlete's heart.
对25名产期服用可卡因的人士进行心脏扫描后发现，其中83%的人出现结构损伤现象，47%的人其处于较低位置的左心室出现扩大现象。
Scans of the hearts of 25 men with long-term history of cocaine use picked up structural damage in 83% of participants and swelling in the lower left ventricle in around 47%.
这种弱化导致左心室异常扩大至底部。
This weakening causes the left ventricle to expand abnormally at the bottom.
运动员的心脏形态是相对明确界定。那就是所有心室都扩大，尤其是那些练体育和耐力相结合的运动。
Morphology of the athlete's heart is relatively well defined. There is enlargement of all cardiac Chambers, which is greatest in those practising sports that combine endurance and power.
结果超声心动图可见多发突入心室肌内的肌小梁和与心室腔交通深陷的小梁间隙，左心室腔扩大。
ResultsNumerous ventricular trabeculae and deep intertrabecular recesses, as well as left ventricular dilatations were found under ultrasonic cardiography.
这些变化包括心室壁肥厚、心腔扩大，其程度与训练强度有关。
These changes may include ventricular wall hypertrophy, and chamber dilatation to varying degrees, often depending on the training regime.
对照组与治疗组同期对应比较，左心室形态逐渐扩大，6个月末最明显，且差异有显著性意义。 同时左心室射血分数同组和两组间对应比较，均有明显改善（P<0.05，P<0.01）。
Results The changes of left ventricular shape and geometry in control group were more obvious than those in treatment group from early phase to 6 months(P<0.05, P<0.01).
随着肺动脉压力的升高、右心室的扩大、心功能的恶化，患者临床不良事件发生率亦大大增加。
The clinical harmful events were higher in the patients with severe pulmonary pressure and dilated right ventriculus.
