The Board has ordered a remand to obtain an addendum opinion from the examiner who conducted the July 2021 VA examination. The examiner is asked to address whether the Veteran's benign heart murmur was a disease or defect, if it was aggravated by her active duty service, and if any superimposed disabilities were due to the heart murmur. Additionally, the examiner must provide opinions on direct service connection for all diagnosed heart disorders, as well as whether any heart disorder was caused or aggravated by her service-connected PTSD.

The Board has remanded the issues of service connection for atrial fibrillation, benign prostatic hypertrophy with outflow obstruction, congestive heart failure, and hypertension due to inadequate VA opinions. The Veteran's exposure during service is conceded to include asbestos and gas chamber exposures.

The Veteran's appeal for an initial rating higher than 30 percent for cardiomegaly with cardiac hypertrophy and valvular heart disease has been dismissed due to the appellant withdrawing the appeal.

The Board has decided to remand the case due to insufficient consideration of secondary service connection for coronary artery disease (CAD) related to the Veteran's service-connected foot disability and depression.

The Veteran's claims for hypertension, CHF and ventricular arrhythmia, atrial fibrillation, diabetic peripheral neuropathy of the right lower extremity affecting the femoral nerve, and diabetic peripheral neuropathy of the left lower extremity affecting the femoral nerve were denied as there is no evidence that these conditions arose prior to July 31, 2024.,The effective dates for service connection for CHF and ventricular arrhythmia, atrial fibrillation, diabetic peripheral neuropathy of the right lower extremity affecting the femoral nerve, and diabetic peripheral neuropathy of the left lower extremity affecting the femoral nerve were denied as there is no evidence that these conditions arose prior to July 31, 2024.
