Also known as: High blood pressure in the lungs
Raymond presents with syncope, chest pain, and difficulty climbing stairs. He is diagnosed with pulmonary hypertension caused by blood clots in the pulmonary arteries. Sam performs surgery to remove clots and insert a vascular umbrella, but Raymond suffers cardiac arrest and hemorrhage during the procedure. He ultimately requires a lung transplant, and Sam is tested as a potential living donor.
Also known as: Blood clot in lung
Raymond has blood clots lodged in his pulmonary arteries causing his pulmonary hypertension and symptoms. Sam attempts surgical removal of the clots but Raymond bleeds excessively due to anticoagulants, nearly dying on the table.
Also known as: Lung failure
Following the surgical complications, Raymond's lung is so damaged that he requires a lung transplant to survive. Sam is tested as a potential living related donor and is found to be a match, though Raymond ultimately refuses the donation.
