Calcificantions make repeat pericardiectomy much more difficult and less successful. Unfortunately, this is the only option that he has at this point if the disease process is related to constriction. Sometimes that's difficult to prove. He should have a

Left heart ventricular angiography catheterization to look for pressure changes in both lower chambers of the heart to ensure that consitriction is the disease process at stake. Infrequently, advanced calcifications and inolvement of the ventricular wall may create a restrictive physiology that is very difficult to deal with surgically. Often times the surgeon won't even consider surgery in such a situation because of high risk. I am not aware of any new surgical techniques for pericardial disease.
