Salsa King Loses a Step

What is a burrito or taco without the special sauce? “What’s in a name? That which we call a rose, by any other word would smell as sweet.” Okay, so Shakespeare knew nothing about tacos, but could he dance? We will never know, but the same name we use to make a burrito special we use to shake things up with rhythm. Salsa is the special dance developed in Cuba to the Latin beat. And herein is the dilemma; they say that “it” is in the blood, but ultimately as one ages, things can and do wear out, especially if one eats too much “salsa”, without dancing “salsa”. And it so happened to Juan. In his youth he was the king of salsa, but he stopped exercising for years, continued to indulge in food and mojitos until tipping into obese territory. At his daughter’s wedding he decided to demonstrate his famous moves and immediately began to feel chest pains, palpitations cause by irregular heartbeats, fatigue, dizziness and the need to lie down. Our former salsa king was rushed to ED (while the wedding revelries continued, of course), where he was diagnosed with an aortic valve prolapse and right coronary artery occlusion. The decision was made to first place a stent into the right coronary artery before fixing the prolapse. Which indicated valve is associated with the right coronary artery ostium?

Ostium of right coronary artery is indicated by which numbered line?
