This study compares two ways of giving a heart imaging drug called **Lumason®**. The study is for people with heart images that aren't clear enough (this is called suboptimal LV EBD). LV EBD stands for left ventricular endocardial border detection, which helps doctors see the heart's inside edge. The study will use two methods: a *continuous infusion* (a slow, steady flow) of diluted Lumason® and a *bolus administration* (a quick, one-time dose) of undiluted Lumason®.

• The study will require your participation for a specific period, but the exact length is not mentioned.
• You must be at least 18 years old and have a specific heart condition to join.
• Certain health conditions, like severe heart failure or recent heart attack, may prevent you from joining.

Participants need to give written consent and follow the study rules. If you are pregnant or taking certain medications, you might not be eligible. Always talk to your doctor before joining a study to understand the risks and benefits.
