Cardiac Structural Anomalies and Repair
Research Guide
What is Cardiac Structural Anomalies and Repair?
Cardiac Structural Anomalies and Repair refers to surgical ventricular reconstruction and repair techniques addressing ventricular complications following myocardial infarction, including postinfarction ventricular septal defect, ischemic and dilated cardiomyopathy, cardiac support devices, and coronary artery bypass.
This field encompasses 38,804 papers focused on risk factors, outcomes, and surgical methods for ventricular issues after myocardial infarction. Techniques target left ventricular dysfunction, postinfarction ventricular septal defects, and cardiomyopathies. Growth data over the past five years is not available.
Topic Hierarchy
Research Sub-Topics
Surgical Ventricular Reconstruction
This sub-topic covers techniques like the Surgical Anterior Ventricular Endocardial Restoration (SVR) for reshaping post-infarction left ventricles. Researchers compare outcomes, patient selection, and remodeling effects.
Postinfarction Ventricular Septal Defect
This sub-topic studies diagnosis, timing, and surgical/percutaneous repair of VSD ruptures after MI. Researchers analyze hemodynamic management and mortality predictors.
Ischemic Cardiomyopathy
This sub-topic examines ventricular dysfunction from coronary disease, viability assessment, and revascularization strategies. Researchers evaluate medical vs. surgical management in advanced stages.
Dilated Cardiomyopathy Surgical Management
This sub-topic investigates volume reduction surgeries, dynamic cardiomyoplasty, and device therapies for end-stage dilated hearts. Researchers assess long-term functional recovery and selection criteria.
Cardiac Support Devices
This sub-topic covers passive ventricular constraint devices and active assist systems like LVADs for remodeling prevention. Researchers study biocompatibility, reverse remodeling, and weaning protocols.
Why It Matters
Surgical ventricular reconstruction and repair improve survival and quality of life in patients with post-myocardial infarction complications. "Long-Term Use of a Left Ventricular Assist Device for End-Stage Heart Failure" by Rose et al. (2001) demonstrated a clinically meaningful survival benefit and improved quality of life using left ventricular assist devices in advanced heart failure patients ineligible for transplant, with 3933 citations reflecting its impact. "Effect of Captopril on Mortality and Morbidity in Patients with Left Ventricular Dysfunction after Myocardial Infarction" by Pfeffer et al. (1992) showed captopril reduced mortality and cardiovascular events in asymptomatic left ventricular dysfunction post-infarction, influencing medical management alongside surgery. Early revascularization in cardiogenic shock, as in "Early Revascularization in Acute Myocardial Infarction Complicated by Cardiogenic Shock" by Hochman et al. (1999), addresses acute structural failures, reducing death rates in hospitalized myocardial infarction cases.

Where to Start
"Effect of Captopril on Mortality and Morbidity in Patients with Left Ventricular Dysfunction after Myocardial Infarction" by Pfeffer et al. (1992) is the starting point for beginners, as it provides foundational evidence on managing left ventricular dysfunction post-myocardial infarction with medical therapy that complements surgical repair.
Key Papers Explained
"Effect of Captopril on Mortality and Morbidity in Patients with Left Ventricular Dysfunction after Myocardial Infarction" by Pfeffer et al. (1992, 5925 citations) establishes medical management benefits for left ventricular dysfunction post-infarction. "Long-Term Use of a Left Ventricular Assist Device for End-Stage Heart Failure" by Rose et al. (2001, 3933 citations) builds on this by introducing mechanical support as an alternative for advanced cases. "Early Revascularization in Acute Myocardial Infarction Complicated by Cardiogenic Shock" by Hochman et al. (1999, 3042 citations) connects acute interventions to prevent progression to structural failure needing repair.

Frequently Asked Questions
What are the main surgical techniques in cardiac structural anomalies repair?
Surgical techniques include ventricular reconstruction, coronary artery bypass, and use of cardiac support devices for post-myocardial infarction complications. These address left ventricular dysfunction, postinfarction ventricular septal defects, ischemic cardiomyopathy, and dilated cardiomyopathy. Outcomes focus on risk factors and long-term survival.
How do left ventricular assist devices function in repair?
"Long-Term Use of a Left Ventricular Assist Device for End-Stage Heart Failure" by Rose et al. (2001) showed left ventricular assist devices provide survival benefits and quality-of-life improvements in advanced heart failure patients. They serve as alternatives to cardiac transplantation in selected cases. The study reported clinically meaningful outcomes in end-stage cases.
What is the role of captopril in post-infarction ventricular repair?
"Effect of Captopril on Mortality and Morbidity in Patients with Left Ventricular Dysfunction after Myocardial Infarction" by Pfeffer et al. (1992) found long-term captopril administration improved survival and reduced morbidity in asymptomatic left ventricular dysfunction after infarction. Benefits included fewer major cardiovascular events. This supports adjunct medical therapy to surgical repair.
How does early revascularization impact cardiogenic shock?
"Early Revascularization in Acute Myocardial Infarction Complicated by Cardiogenic Shock" by Hochman et al. (1999) evaluated emergency revascularization in shock patients post-myocardial infarction. It targeted the leading cause of in-hospital death. The trial assessed outcomes in randomized patients.
What defines the current state of this field?
The field includes 38,804 works on surgical ventricular reconstruction and repair post-myocardial infarction. Key areas cover postinfarction ventricular septal defect, cardiomyopathies, and support devices. No recent preprints or news coverage from the last 12 months or six months is available.

Recent Trends
The field maintains 38,804 papers with no specified five-year growth rate.
High-citation works from 1992-2001, such as Pfeffer et al. (5925 citations) and Rose et al. (3933 citations), continue to define standards for left ventricular repair post-infarction.
Absence of recent preprints in the last six months and news in the last 12 months shows no documented shifts.
