    <p>AF  =  atrial fibrillation; ASH  =  asymmetrical septal hypertrophy; CLBBB  =  complete left bundle branch block; CRBBB  =  complete right bundle branch block; HCM  =  hypertrophic cardiomyopathy; IVST  =  intraventricular septal wall thickness; LAD  =  left atrial dimension; LVDD  =  left ventricular end-diastolic dimension; LVEF  =  left ventricular ejection fraction; MWT  =  maximal wall thickness; PWT  =  posterior wall thickness.</p

    Relationships between the microscopic fibrosis fraction and the LGE fraction in the HCM patients.

    <p>(<b>A</b>) A fair correlation was found between the LGE fraction and the total fibrosis fraction in biopsied specimens (N  =  21). (<b>B</b>) To examine whether the LGE fraction correlated with the microscopic collagen fraction in HCM with preserved LV systolic function, 5 end-stage HCM patients were excluded from analyses. In the remaining 16 HCM patients, a correlation between the LGE fraction in the whole heart and the microscopic collagen fraction in biopsied specimens was observed (r  =  0.62, p  =  0.011).

    <p>(<b>A</b>–<b>C</b>) Typical histology from endomyocardial biopsy. Upper panels; no pathological fibrosis (<b>A</b>), increased interstitial fibrosis (<b>B</b>), and severe myocardial scarring (<b>C</b>). Slides were stained with Azan dye. Interstitial fibrosis was defined as increased interstitial collagen without evidence of cardiomyocyte loss <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101465#pone.0101465-Seidman1" target="_blank">[9]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101465#pone.0101465-John1" target="_blank">[22]</a>. Lower panels: areas of fibrosis visualized by ImageJ software. Fibrosis volume fraction determined by digital planimetry was 2% (<b>A</b>), 15% (<b>B</b>) and 45% (<b>C</b>), respectively. Myocardial scarring was defined as increased interstitial collagen with evidence of cardiomyocyte loss <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101465#pone.0101465-Seidman1" target="_blank">[9]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101465#pone.0101465-John1" target="_blank">[22]</a>. The presence of islands of surviving cardiomyocyte among fibrotic tissues was considers as evidence of cardiomyocyte loss <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101465#pone.0101465-Basso1" target="_blank">[23]</a>. (<b>D</b>) Islands of surviving cardiomyocyte (arrows) among fibrotic tissues observed with high magnification of Image C. (<b>E and F</b>) Defining and quantifying LGE. Representative HCM patients with no LGE (<b>E</b>) and with positive LGE (<b>F</b>). Areas of LGE (traced by yellow lines) were quantified by manual planimetry and presented as percentage of left ventricular areas (traced by blue lines). Total of 6 short axes views were analyzed in each HCM patient. The LGE volume fraction was 0% in Case D, and 16% in Case E. Scale bars represent 200 µm. CMR  =  cardiac magnetic resonance imaging, HCM  =  hypertrophic cardiomyopathy, LGE  =  late gadolinium enhancement.</p

    <p>(<b>A</b>) Myocardial scarring was observed both in CMR and endomyocardial biopsy. (<b>B</b>) LGE was present in CMR, but there was no evidence of microscopic myocardial scarring. Scale bars represent 200 µm. Abbreviations as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101465#pone-0101465-g001" target="_blank">Figure 1</a>.</p
