[Left-ventricular function before and after aneurysmectomy]

Area of Science:

• Cardiovascular Surgery
• Cardiac Physiology
• Medical Engineering

Background:

• Postinfarction heart aneurysm poses significant risks to cardiac function.
• Central hemodynamics are critically affected in patients with heart aneurysms.
• Surgical intervention is often necessary to manage these complications.

Purpose of the Study:

• To report clinical findings on central hemodynamics in patients with postinfarction heart aneurysm.
• To evaluate the impact of aneurysmectomy on myocardial contractility and cardiac volumes.
• To present a method for recording hemodynamic data during surgical treatment.

Main Methods:

• Examined central hemodynamics and myocardial contractility in 92 patients during surgery.
• Performed aneurysmectomy to address the postinfarction heart aneurysm.
• Recorded and analyzed hemodynamic information, including blood pressure and flow rate.

Main Results:

• Aneurysmectomy normalized residual volumes of heart cavities during surgery.
• Significant increase in myocardial performance was observed post-aneurysmectomy.
• Surgical treatment demonstrated positive effects on cardiac function.

Conclusions:

• Aneurysmectomy is an effective surgical treatment for postinfarction heart aneurysm.
• The procedure leads to improved cardiac volumes and enhanced myocardial performance.
• The discussed method for hemodynamic monitoring aids in evaluating surgical outcomes.
