153 Possible Causes for Left Bundle Branch Block, Mitral Valve Insufficiency

  • Acute Myocarditis

    […] of the mitral or tricuspid valve), a pericardial friction rub, and a displaced punctum maximum.[] One patient had left bundle-branch block. Peak serum creatine kinase levels were elevated in six of the eight patients (range, 150 to 1518 units per liter).[] bundle branch block (LBBB) are associated with higher rates of cardiac death or heart transplantation Radiology description Chest Xray: cardiomegaly due to chamber dilation[]

  • TTR Amyloidosis with Cardiomyopathy

    The electrocardiogram (ECG) showed sinus rhythm, HR 67 bpm, first-degree atrioventricular block, low voltage in the frontal leads and complete left bundle branch block ( Figure[] bundle-branch block.[] Half of the patients with SSA had right bundle branch block compared with only 1 of the 16 nonpaced patients with AL amyloidosis ( P .01).[]

  • Anomalies of Coronary Artery Origin

    […] stenosis insufficiency absence tricuspid valves stenosis atresia Ebstein's anomaly Hypoplastic right heart syndrome Uhl anomaly Left aortic valves stenosis insufficiency[] […] bicuspid mitral valves stenosis regurgitation Hypoplastic left heart syndrome Other Dextrocardia Levocardia Cor triatriatum Crisscross heart Brugada syndrome Coronary artery[] Eisenmenger's syndrome R L, with other conditions: Tetralogy of Fallot Atrioventricular septal defect L R: Ostium primum Valvular heart disease / heart chambers Right pulmonary valves[]

  • Hereditary ATTR Amyloidosis

    Other common ECG abnormalities include repolarization alterations; anterior, inferior, or lateral pseudoinfarct patterns; left anterior hemiblock; bundle branch block; ischemic-type[] The conduction system is commonly affected, leading to bundle branch block and, occasionally, atrioventricular (AV) and sinoatrial block.[] Myocardial infiltration progressively increases the thickness of the left and right ventricular walls and the interventricular septum.[]

  • Secondary Cardiomyopathy

    The ECG proved the left bundle branch block was gone and negative T-waves appeared in the antero-lateral face with late normalization.[] bundle-branch block I44.0 Atrioventricular block, first degree I44.1 Atrioventricular block, second degree I44.2 Atrioventricular block, complete I44.3 Other and unspecified[] The five most common abnormalities seen on the ECG are Q waves (from a previous MI), diffuse ST-segment abnormalities, left bundle branch block (or any intraventricular conduction[]

  • Acute Bacterial Endocarditis

    valve disorders I34.0 Nonrheumatic mitral (valve) insufficiency I34.1 Nonrheumatic mitral (valve) prolapse I34.2 Nonrheumatic mitral (valve) stenosis I34.8 Other nonrheumatic[] This is the first case found in which the partial left bundle branch block (LBBB) was of acute inflammatory origin.[] In 1 patient, only T-wave inversion was reported and 1 patient had a previously undocumented left bundle branch block and first-degree AVB that quickly progressed to complete[]

  • Dilated Cardiomyopathy

    […] and tricuspid valve insufficiency Complications Conduction defects–eg atrial & ventricular tachyarrhythmias and fibrillation Management Supportive–eg rest, weight control[] bundle branch block and/or ventricular pacemaker implantation.[] The valve leaflets become leaky, resulting in mitral regurgitation (or mitral insufficiency) whereby the blood moves backward from the left ventricle to the left atrium, rather[]

  • Endocardial Fibroelastosis

    Abstract Surgical treatment of mitral insufficiency and aortic valve stenosis associated with endocardial fibroelastosis has not been well documented.[] Two patients developed left bundle branch block and one developed right bundle branch block with left, but anterior-fascicular block.[] bundle-branch block I44.0 Atrioventricular block, first degree I44.1 Atrioventricular block, second degree I44.2 Atrioventricular block, complete Reimbursement claims with[]

  • Myocardial Infarction

    These include congestive heart failure, cardiogenic shock, acute mitral valve insufficiency (due to papillary muscle ischemia, infarction, or rupture), ventricular free wall[] bundle branch block (LBBB)) development of pathological Q wave changes in the ECG imaging evidence of new loss of viable myocardium or new regional wall motion abnormality[] Operation for acute postinfarction mitral insufficiency and cardiogenic shock. J Thorac Cardiovasc Surg. 1985 ; 89 :525–30. Google Scholar 473.[]

  • Mitral Valve Incompetence

    valve (disorder) Mitral valve incompetence congenital mitral insufficiency congenital mitral regurgitation mitral regurgitation MR Mitral insufficiency, MI Congenital insufficiency[] RV pacing simulates the effects of left bundle branch block, with dyssynchronous contraction of the left and right ventricles.[] Less commonly, signs of pulmonary hypertension, such as right ventricular hypertrophy or right bundle branch block, may be seen.[]
