Hi:
Life expectancy is highly-variable, as one has to take into consideration various factors and conditions, such as possible complications (some unforeseen) and the progression of the disease, which can sometimes be accelerated.
"Is open heart surgery a good option for......"
Well it certainly may/can be for left main stenosis of 50% or greater, though with other coronary arteries, such as the right coronary artery, left anterior, or left circumflex, doctors typically consider/may perform bypass (or angioplasty with or without stents) on blockages that are 70%/75% or greater. Sometimes, customized drug-therapy is the chosen course of treatment for the patient initially.
About the Left Main (LM)
Noteworthy, an absolute worst case scenario would be a total (100%) occlusion/blockage, as the LM feeds a massive left ventricular area, and while
extremely rare, is
almost always invariably fatal.The LM arises from the aorta (the largest artery in the human body), typically 1 to 25 mm in length, with the diameter of a straw, and then splits (bifurcates) into the left anterior descending (LAD) and the left circumflex (LCX).
There is also coronary artery dominance, e.g., right-dominant, left-dominant and co-dominant, something that is seldom talked about, discussed, though
can be extremely important in certain cases (such as LM stenosis).
DominanceDepending on which coronary artery (left or right) crosses the midline of the heart posteriorly (back wall) i.e., the crux, dominance is determined. In most individuals (approximately 85%), it is the right coronary artery.

Angioplasty OK for Major Heart Artery
Study Shows Angioplasty May Offer Option to Open Blockages in Heart Artery That Supplies Most of Heart's Blood - April 1, 2008 Angioplasty may be a perfectly good option for opening up blockages in the major artery that provides most of the blood to the heart, South Korean researchers say.
They studied people with
blockages in the left main coronary artery. It supplies blood to the left side of the heart muscle, which is the side that pumps fresh blood to the rest of the body. Current guidelines call for these patients to undergo bypass surgery.

Experts Debate Stents vs. Bypass for Left Main Coronary Artery Disease - May 11, 2007
The Stakes Are High in Artery Supplying Blood to Two-Thirds of the Heart (Excerpt)
Coronary artery bypass surgery has been the preferred treatment for patients with a
blockage in the left main coronary artery, the conduit that supplies blood to about two-thirds of the heart.
HOWEVER, in recent years this has been challenged by stent placement in this critical artery. Trusting treatment of such a critical vessel to percutaneous coronary intervention (PCI) is anathema to some. To others, it is the
reasonable next step, given recent advances in stent technology.
