We are stunned and very saddened by news of the untimely passing of Christopher Nicholson, founder of Deep Sea Systems International and a pioneer in the development of underwater remote operated vehicles (ROVs). Chris was also an ardent supporter or our MATE ROV programs. Here is a link to an interview with Chris:

Dear friends,

On December 22, 2015 I suffered a surprise, massive heart attack. I was given quintuple heart bypass surgery at  doctoBeth-Israel-Deaconess Hospital in Boston, MA. Thers say I am healing well. I am grateful to the many family, friends and neighbors who expressed their concern and offered encouragement. More details on the story Cardiac Saga below.

Feb. 17, 2016 - CARDIAC SAGA

On December 21, 2015 I experienced some indigestion and mild chest discomfort that lasted through the night. We had just eaten a lunch buffet at a local Indian restaurant. We have eaten at this restaurant many times and I have never had a problem, but I assumed the discomfort was caused by the spicy food.

The next morning I was doing some local errands. Apparently after getting in and starting my car I must have blacked out. I woke up in an ambulance on the way to Lawrence General Hospital. They told me I had been found slumped over the wheel of the car. At the hospital they did all sorts of tests including cardiac catherization. They determined that I had a massive heart attack and that I should have surgery in Boston. They put me in an ambulance that took me to Beth Israel Deaconess Medical Center where Dr. Senthilnathan and his team did a quintuple coronary artery bypass surgery (CABG - colloquially called a “cabbage”) the following day. They took veins from my both my legs to use for the surgery. After the operation I was taken to the cardiac ICU until December 27 when I was transferred to a regular hospital room at Beth Israel Deaconess Cardiac Vascular Institute.

On December 29 I was taken to the Meadows at Edgewood, a rehab facility in North Andover, Mass. The people at this facility were wonderful and I appreciate everything they did for me. On January 20, 2016 I was allowed to go home. A number of the staff came by to say goodbye and wish me well.

On January 28 I had some discomfort similar to the symptoms I had the day of the heart attack. It turns out that I had an appointment for a physical with a new primary care physician. When I arrived I told about my symptoms. The doctor called 911 and I found myself in an ambulance headed back to Lawrence General Hospital. They ran all sorts of tests and kept me there for the night. It was quite a scare, but in the end it turned out to be a false alarm and I was allowed to go home.

At home I had visiting nurses as well as a great physical therapist. There was also a machine that takes my oxygen levels, blood pressure and weight and transmits the data to a central office.

Except for the mild “indigestion”, this whole thing came completely by surprise. I always thought I had a reasonably healthy diet and maintained a fairly active lifestyle. I have never smoked and rarely drink (unless I am hanging out with archaeologists, divers, bonsai enthusiasts, model railroaders or Boston Red Sox fans :). I have had a lot of discussions with doctors about “how could this happen.”  It turns out there are a variety of possibilities. It could be too many chicken wings and spare ribs. It could be not enough cardiac exercise. It could be stress. The most likely is simply hereditary - there is a history of heart disease in my family.

Thank you everyone for your kindness.
